Performance Evaluation of Plastic Drum Septic Tanks Equipped with Recycled Nylon Net Biofilters for Domestic Wastewater Treatment in Riverbank Communities
type: item
description: Water pollution caused by the direct discharge of domestic wastewater from toilets into watercourses remains a serious environmental health issue, particularly in riverside settlements with limited access to adequate sanitation facilities. This study aims to evaluate the performance of septic tanks made from plastic drums fitted with biofilters made from used nylon netting in improving the quality of domestic wastewater based on the parameters of Biochemical Oxygen Demand (BOD) and Total Suspended Solids (TSS). The study employed a quasi-experimental design with a post-test only control group design, conducted in the villages of Ambawang Kuala and Kuala Mandor B, Kubu Raya Regency. A total of eight plastic drum septic tanks were used, comprising four treatment units fitted with biofilters made from used nylon netting and four control units without biofilters. Wastewater samples were collected from the septic tank outlets and analysed for BOD and TSS using standard laboratory methods. A total of 64 samples were analysed; the data were then processed descriptively and tested using an independent t-test after meeting the assumptions of normality and homogeneity. The results of the study showed that the mean BOD concentration in the treatment group (5.74 mg/L) was lower than that in the control group (7.79 mg/L), whilst the mean TSS concentration in the treatment group was 3.45 mg/L and in the control group 3.17 mg/L. However, there were no statistically significant differences for either the BOD (p=0.227) or TSS (p=0.883) parameters. These results indicate that the use of biofilters made from used nylon netting tends to enhance the reduction in BOD levels, but has not yet yielded a significant improvement in wastewater quality under the conditions of this study. Therefore, this technology has the potential to be developed as an alternative for a simple, low-cost and environmentally friendly sanitation system; however, it still requires design refinements, longer operat…

SEM-EDS Characterization of Metal-Bearing Particles in Kali Kabur River Sediments, Mimika, Central Papua, Indonesia: A Preeliminary Mineralogical Assessment
type: item
description: The Grasberg porphyry copper-gold mining district in Central Papua, Indonesia, has historically discharged tailings into the Ajkwa river system, raising concerns about downstream heavy-metal contamination in tributaries such as Kali Kabur, Mimika Regency. Because bulk geochemical techniques (e.g., XRD, XRF, ICP-MS) characterize average sediment composition but cannot resolve which specific mineral grains host which metals, this preliminary study applied Scanning Electron Microscopy with Energy Dispersive X-ray Spectroscopy (SEM-EDS) spot analysis to two grab sediment samples from Kali Kabur (TS1, Lab No. 3647.25; TS2, Lab No. 3648.25), examined at the accredited tekMIRA laboratory (Certificate of Analysis No. 1044/LFM/10/2025) following internal method PU-3002FM. Backscattered electron imaging guided selection of eight metal-bearing particles (four per sample) for quantitative elemental analysis in weight percent. Results identified a Cu-Fe-S particle consistent with a chalcopyrite-like phase (TS1, Spectrum 1: Cu 44.78 wt%, Fe 22.58 wt%, S 32.64 wt%), a near-stoichiometric pyrite grain (TS1, Spectrum 2: S 47.19 wt%, Fe 52.81 wt%), iron oxide particles in both samples, quartz/silicate particles in both samples, and, in TS2, a Ti-Fe-Al-Si-O particle consistent with altered ilmenite/titanomagnetite intergrown with aluminosilicates, together with an Mn-bearing aluminosilicate phase. These assemblages are mineralogically consistent with the known porphyry Cu-Au mineralization and associated alteration facies of the Grasberg district. However, because no upstream or background reference samples, bulk metal concentrations, or independent mineralogical confirmation (e.g., XRD) were obtained, the data cannot, by themselves, distinguish natural geogenic inputs from mining-derived material, nor support quantitative statements about bioavailability or ecological/human health risk. The findings are reported as a preliminary, particle-level screening that complements but does not…

Human Health Risk Assessment Based on Lead (Pb) Exposure from Drinking Water and Aquatic Food in Pontianak, Indonesia
type: item
description: Lead (Pb) exposure through drinking water and aquatic food remains a serious public health issue, particularly in tropical urban areas. This study aims to identify the main sources of Pb exposure in the community of Pontianak City through analysis of rainwater, refill water, tilapia, shrimp, shellfish, and fish-based processed foods. The study was conducted using a cross-sectional observational design, involving 37 rainwater samples, 23 refill water samples, and 60 food samples. Analysis using the AAS method showed that the average Pb level in rainwater reached 0.093 mg/L (0.040–0.160 mg/L) with 100% of samples exceeding the WHO threshold (0.01 mg/L), while in refilled water the average was 0.012 mg/L (0.009–0.020 mg/L) and 39.1% exceeded the standard. In food, shellfish had the highest Pb content at 0.42 mg/kg (0.20–0.68 mg/kg) with 42.9% exceeding the Codex standard (0.3 mg/kg), followed by shrimp at 0.35 mg/kg (36.7%), tilapia at 0.22 mg/kg (13.6%), and fish nuggets 0.05 mg/kg (0%). Daily intake estimates show that rainwater consumption contributes 0.186 mg/day, much higher than refill water (0.024 mg/day). The combination of rainwater and shellfish resulted in a total Pb intake of 0.228 mg/day (81.6% from water, 18.4% from food), while the combination of refilled water and shellfish was only 0.066 mg/day. The highest Estimated Weekly Intake (EWI) value reached 26.6 µg/kg bw/week, approaching the international reference threshold. The results of the study confirm that collected rainwater is the dominant route of exposure, while shellfish and shrimp are significant additional sources. These findings underscore the urgency of mitigation through improvements in rainwater harvesting quality, enhanced monitoring of refill depots, and control of consumption of certain aquatic foods.

Participation and Policy Support for a Campus-Based Community Recycling Initiative in Yogyakarta, Indonesia
type: item
description: A campus-based community recycling initiative was implemented in a higher health vocational education in Yogyakarta, Indonesia, through a mandatory institutional policy to promote sustainable monthly campus waste management. This study aimed to assess participation, routine waste management behavior, and support for the continuation of the policy. A cross-sectional online survey was conducted among campus community members, including students, lecturers, and administrative staff. A total of 607 respondents completed the questionnaire and were included in the analysis. Univariate and multivariate logistic regression analyses with 95% confidence intervals (CIs) were used to identify factors associated with routine monthly waste management and support for policy continuation. Overall, 91.4% of respondents were registered as member of this initiative, 88.5% were aware of the mandatory policy, and 96.5% reported sorting waste before disposal. However, only 46.1% reported routine monthly waste management. In the adjusted model, routine monthly waste management was associated with perceived availability of digital services (AOR 3.20; 95% CI 2.15–4.77) and waste reduction with family or close friends (AOR 1.99; 95% CI 1.28–3.08). Respondents with compliance-only motivation had lower odds of routine participation than those with a compliant-internalized profile (AOR 0.40; 95% CI 0.21–0.76). Support for policy continuation was associated with routine monthly waste management (AOR 3.09), perceived availability of digital services (AOR 2.57), perceived environmental cleanliness (AOR 3.90), perceived program effectiveness (AOR 4.47), and higher overall perception scores (AOR 2.92). The mandatory campus-based recycling policy achieved high formal participation, but routine monthly participation remained limited. Sustained participation depends not only on institutional enforcement but also on internalized motivation, access to digital services, social support, and perceived progr…

Waste Characterization and Integrated Management Strategy for Small-Island Tourism in Derawan, Indonesia
type: item
description: This study aims to evaluate the waste generation and composition characteristics as a technical basis for designing an Integrated Solid Waste Management (ISWM) strategy on Derawan Island, a small island tourism destination. By applying a quantitative method referring to the SNI 19-3964-1995 standard, data were collected over eight consecutive days from three different sources: households (stratified random sampling), the commercial sector (purposive sampling), and marine debris (transect method). The analysis results showed that total daily waste generation reached 2,810.05 kg/day. The specific generation rate of 1.652 kg/capita/day was far above the national average, indicating a "double burden" phenomenon due to high tourism activity. In terms of composition, the waste stream was dominated by organic material (53.99%), followed by inorganic waste (40.18%) and hazardous waste (5.83%). These findings prove that the conventional "collect-transport-dispose" model is highly vulnerable and uneconomical given the 1.5-hour sea transport distance to the final disposal site on the mainland. Therefore, this characterization data supports a decentralized ISWM framework that prioritizes on-site bioconversion of the organic fraction (e.g., composting and utilization of Local Microorganisms/MOL), complemented by high-value recycling recovery. This baseline data-driven approach can theoretically reduce the final residue that must be transported by sea to only 18.15% of its initial mass, thereby overcoming acute logistical constraints while ensuring environmental sustainability for coral reef-based ecotourism.

Ethanolic Peel Extract Attenuates Isonazid-induced Hepatic Injury in Rats via Reduced NF-kB, and Caspase 3 Expression
type: item
description: Isoniazid can induce hepatotoxicity and liver fibrosis via oxidative stress, NF-κB, and caspase-3 pathways. Garcinia mangostana L. (mangosteen) peel extract, rich in xanthones, offers anti-inflammatory and anti-apoptotic properties that may mitigate drug-induced liver injury. To evaluate the effects of mangosteen peel ethanol extract on NF-κB p65, caspase-3 expression, and hepatic fibrosis in isoniazid-treated Wistar rats. In this experimental study, 28 male Wistar rats were divided into four groups: negative control (NC), positive control (PC; isoniazid 50 mg/kg), and two treatment groups receiving isoniazid plus mangosteen extract at 250 mg/kg (I1) and 500 mg/kg (I2) for 30 days. Liver tissues were analyzed using immunohistochemistry (NF-κB, caspase-3) and Masson’s trichrome staining (fibrosis). The 500 mg/kg dose significantly reduced NF-κB p65 and caspase-3 expression and mitigated hepatic fibrosis compared to the PC group (p < 0.05). The 250 mg/kg dose showed less pronounced effects. Garcinia mangostana L. peel extract, especially at 500 mg/kg, effectively attenuates isoniazid-induced liver injury by downregulating NF-κB and caspase-3 in isoniazid-induced Wistar rats. These findings suggest its potential as an adjunct in preventing isoniazid-induced hepatic injury in a preclinical setting. Additional translational and clinical investigations are needed to determine its efficacy and safety as a potential hepatoprotective agent in humans.

Hospital Disaster Resilience in Indonesia: An Evidence-Based Synthesis of Flood and Earthquake Preparedness
type: item
description: Indonesia is one of the most disaster-prone countries in the world due to exposure to earthquakes, floods, tsunamis, volcanic eruptions, and climate-related hazards. Hospitals play a critical role in maintaining healthcare delivery during disasters, yet their resilience capacity varies. This study synthesized evidence on hospital disaster resilience in Indonesia, focusing on preparedness for flood and earthquake hazards. An evidence-based descriptive synthesis was conducted using peer-reviewed studies, national reports, policy documents, and international guidance. Findings were analyzed across four resilience domains the Hospital Safety Index: structural and non-structural safety, emergency management systems, continuity of essential services, and governance and policy integration. The review found that improvements in hospital resilience were most evident in governance, disaster management planning, and policy integration, largely driven by accreditation requirements and national disaster risk reduction initiatives. However, structural resilience remains insufficient in many facilities, particularly regarding seismic preparedness and non-structural mitigation measures. Flood preparedness is more advanced than earthquake preparedness because hydrometeorological hazards occur more frequently. Persistent vulnerabilities were identified in continuity of essential services, including electricity, water supply, sanitation systems, and healthcare waste management. Although disaster preparedness plans are increasingly available, operational readiness through emergency exercises remains inconsistent. Overall, hospital disaster resilience in Indonesia remains uneven, characterized by stronger administrative preparedness than infrastructural and functional resilience. Strengthening disaster-safe hospitals requires integrated resilience frameworks, climate-resilient health infrastructure, sustained investment in emergency preparedness, enhanced workforce capacity, and stronge…

The Hepatoprotective Role of Ethanolic Mangosteen Peel Extract (Garcinia mangostana L.) on MDA, TNF-α, E-Selectin, and SGPT Levels in Isoniazid-Induced Liver Fibrosis Wistar Rats
type: item
description: Isoniazid is a first-line anti-tuberculosis drug known to cause drug-induced liver injury (DILI) through oxidative stress and inflammatory mechanisms that contribute to the development of liver fibrosis. Mangosteen peel (Garcinia mangostana L.) contains xanthone compounds with antioxidant and anti-inflammatory properties, making it a potential hepatoprotective agent. This study aimed to determine the role of ethanol extract of mangosteen peel on malondialdehyde (MDA) levels, tumor necrosis factor-α (TNF-α) expression, E-selectin expression, and SGPT levels in the liver of isoniazid-induced fibrosis Wistar rats. This experimental study used a post-test only control group design. Twenty-eight male Wistar rats were randomly divided into four groups: negative control group, positive control group (isoniazid 50 mg/kgBW/day), treatment group 1 (isoniazid + mangosteen peel ethanol extract 250 mg/kgBW/day), and treatment group 2 (isoniazid + mangosteen peel ethanol extract 500 mg/kgBW/day) for 30 days. MDA and SGPT levels were measured using spectrophotometry, while TNF-α and E-selectin expression were assessed using immunohistochemistry. Administration of mangosteen peel ethanol extract significantly reduced MDA and SGPT levels and decreased TNF-α and E-selectin expression compared to the positive control group. The most significant reduction was observed in the group receiving the extract dose of 500 mg/kgBW. Mangosteen peel ethanol extract reduces MDA, TNF-α, E-selectin, and SGPT levels in isoniazid-induced Wistar rats. These findings demonstrate its hepatoprotective potential in a preclinical setting, further translational and clinical studies are warranted to evaluate its efficacy and safety in humans as potential hepatoprotective agent.

Spatiotemporal Water Quality Assessment of Lake Mahalona via Google Earth Engine
type: item
description: Freshwater lake ecosystems are increasingly recognized as sensitive indicators of environmental health, where shifts in physicochemical water quality parameters reflect broader ecological pressures from anthropogenic activities and climate variability This study aims to map the spatial distribution, analyze temporal trends, and evaluate the water quality status of Lake Mahalona in Towuti Subdistrict, East Luwu Regency, South Sulawesi, based on pH, TSS, BOD, COD, and ammonia parameters. The analysis was conducted using the GEE platform with Sentinel 2 Level-2A imagery data for pH, TSS, BOD, and COD parameters, as well as GEOS-CF data for ammonia, covering the period from January to November 2025. The methods applied included creating an Area of Interest (AOI), using the JRC Global Surface Water Mapping Layers, v1.4, utilizing Harmonized Sentinel-2 MSI Level-2A (SR), atmospheric correction, cloud and water body masking, outlier removal using the inter-quantile range, deriving functional equations for water quality parameters, and exporting the data. Satellite-derived estimates yielded pH values ranging from 6.587 to 7.154; TSS from 17.55 to 19.821 mg/L; BOD from 3.215 to 7.266 mg/L; COD from 2.857 to 6.116 mg/L; and atmospheric ammonia pressure indicators at 0.001 mg/L. Time-series analysis revealed fluctuations in all parameters, with increases in TSS, BOD, and COD from August to October, while ammonia remained stable at very low concentrations. Based on Government Regulation No. 22 of 2021, the pH, TSS, COD, and ammonia parameters still meet Class II and III water quality standards; however, the BOD value has exceeded the 2 mg/L threshold, indicating organic pollution pressure from anthropogenic activities in the watershed. The GEE-based approach demonstrates considerable potential for efficient spatial and temporal monitoring of lake water quality, providing important baseline information for the sustainable management and conservation of Lake Mahalona.

Comparative Analysis of Aedes spp. Mosquito Oviposition Preferences for Various Natural Attractants in Ovitraps
type: item
description: Dengue fever remains a major public health problem in tropical countries, including Indonesia. Ovitraps are widely used as a simple and cost-effective tool for monitoring and controlling Aedes mosquito populations; however, their effectiveness depends on the type of attractant and trap material used. This study aims to evaluate various types of attractants for *Aedes* mosquito egg traps as part of surveillance efforts. The research method is a quasi-experimental study with a posttest-only control group design was conducted from August to October 2025 in Sokaraja Subdistrict, Banyumas Regency, Central Java, Indonesia. A total of 16 ovitraps consisting of different trap materials (glass, bamboo, coconut shell, and black plastic) and attractants (fermented palm sugar solution, fermented young coconut water, red chili infusion, and clean water as control) were deployed in 15 households. The attractants tested were fermented palm sugar solution (45%), fermented young coconut water (20%), and red chili infusion (15%), all prepared based on preliminary trials. Control treatments included egg traps filled with clean water and transparent glass egg traps to control for material-related effects. This study has received approval from the UNDIP ethics committee with NO. 280/EA/KEPK-FKM/2025. The results showed that egg counts were recorded from ovistrips after a five-day exposure period and analyzed using descriptive statistics and Mann–Whitney tests. Coconut shell ovitraps captured the highest mean number of eggs (67.58), followed by black plastic (26.07) and bamboo traps (20.83), while glass ovitraps showed the lowest mean (0.25). Among attractants, fermented young coconut water produced the highest mean egg count (70.05), followed by red chili infusion (24.38) and fermented palm sugar solution (14.35), whereas clean water showed the lowest value (5.95). Statistical analysis demonstrated significant differences among both ovitrap materials and attractant types (p < 0.05). The…

description: Access to safe drinking water remains a critical public health challenge in South Kalimantan, where peat-influenced water sources exhibit high turbidity, elevated iron concentrations, and acidic pH. This experimental study designed, fabricated, and evaluated a Circular Pipe–Synthetic Ultrafiltration (CP-SKU) device a hydraulic coagulation reactor requiring no mechanical energy input — for treatment of peat-influenced dug well water. Five sequential treatment configurations were tested in triplicate using PAC Powder (100 mg/L) as coagulant. The CP-SKU configuration achieved the best performance: turbidity reduction from 19.8 to 0.47 NTU (97.63%), iron below detection limit (<0.1 mg/L), and pH 6.72 — all compliant with Indonesian Ministry of Health Regulation No. 2 of 2023. Extended trials on high-turbidity raw water (83.67 NTU) confirmed 98% turbidity removal and 99.55% MPN Coliform reduction. However, effluent pH (6.39) fell marginally below the 6.5 regulatory threshold, and residual coliform indicators did not meet zero-tolerance standards, necessitating upstream pH correction and downstream disinfection prior to consumption.

The Green Hospital: A Hybrid Systematic Literature Review and Bibliometric Analysis
type: item
description: In recent decades, Green Hospitals have been the subject of numerous studies, yet conceptual fragmentation and ambiguity persist. Thus, the purpose of this study is to address the fragmentation and conceptual ambiguity in green hospital literature by a hybrid approach that integrates a systematic literature review (SLR) and bibliometric analysis. Unlike prior studies, which are predominantly descriptive, this study provides a structured synthesis, identifies theoretical gaps, and develops an integrative framework. A total of 169 Scopus-indexed articles between 2011 and 2025 were systematically identified using an expanded Boolean search strategy ("Green Hospital" OR “sustainable hospital” OR “green healthcare” OR “eco-friendly hospital”) and analyzed following PRISMA guidelines. Bibliometric analysis was conducted using VOSviewer to map intellectual structure, collaboration networks, and thematic evolution. The study findings indicate that the existing study is heavily concentrated on environmental and infrastructure dimensions, while behavioral, governance, and policy aspects remain underexplored. The study also identifies geographic concentration and potential database bias in the global distribution of the study. Importantly, the study develops an integrated Green Hospital Sustainability Framework (IGHSF) based on an inductive thematic approach. This study contributes to the literature by improving methodological rigor in green hospital studies through a hybrid SLR-bibliometric approach, advancing theoretical understanding of sustainability integration in healthcare systems, and providing actionable insights for policymakers and healthcare managers in implementing sustainable hospital practices.

Occupational Pesticide Exposure and Reduced eGFR in Farmers
type: item
description: Pesticides are frequently utilized in modern farming to sustain crop productivity. However, improper use may pose occupational health risks, including chronic renal toxicity. In Indonesia, evidence regarding long-term kidney effects among farmers remains limited. This study aimed to determine the prevalence of reduced estimated glomerular filtration rate (eGFR) and examine its association with pesticide exposure among horticultural farmers in Wanasari District, Brebes Regency. A cross-sectional analytical study was conducted among 367 farmers aged 18-63 years. Data on pesticide use, personal protective equipment (PPE), smoking habits, health complaints, and hypertension were collected through interviews. Serum creatinine levels were measured enzymatically and used to estimate eGFR. Multivariate logistic regression analysis was applied to identify factors associated with reduced renal function. Several variables showed a significant association with decreased renal function, namely smoking status (OR = 2.972; 95% CI: 1.299-6.001; p = 0.009), pesticide dosage (OR = 4.555; 95% CI: 2.415-8.291; p < 0.001), PPE use (OR = 0.383; 95% CI: 0.199-0.737; p = 0.004), health complaints (OR = 2.972; 95% CI: 1.567-5.636; p = 0.001), hypertension (OR = 2.367; 95% CI: 1.278-4.382; p = 0.006), working period (OR = 15.057; 95% CI: 3.510-64.591; p < 0.001). Working period was the dominant factor associated with decreased kidney function in farmers. This indicates the importance of chronic exposure duration in increasing the risk of pesticide-induced nephrotoxicity. Prevention efforts should focus on controlling exposure duration, improving adherence to PPE use, providing education on pesticide use, and regularly monitoring kidney function.

Viral Load, CD4 Count, NLR, SGPT, and eGFR Levels as Factors Associated with Quality of Life in HIV Patients
type: item
description: Human Immunodeficiency Virus (HIV) infection remains a major global health problem and may affect the quality of life of people living with HIV. Quality of life can be assessed using the World Health Organization Quality of Life-Human Immunodeficiency Virus BREF (WHOQOL-HIV BREF) questionnaire. This study aimed to analyze the association of viral load, CD4 count, neutrophil-to-lymphocyte ratio (NLR), serum glutamic pyruvic transaminase (SGPT), and estimated glomerular filtration rate (eGFR) with quality of life among HIV patients. This observational analytic study used a cross-sectional design and was conducted at the Voluntary Counseling and Testing Clinic of Dr. Moewardi Hospital, Surakarta, Central Java, Indonesia. A total of 100 HIV patients undergoing antiretroviral therapy were included based on predefined inclusion and exclusion criteria. The independent variables were viral load, CD4 count, NLR, SGPT, and eGFR, while the dependent variable was quality of life assessed using the WHOQOL-HIV BREF questionnaire. Clinical and laboratory data were obtained from medical records. Data were analyzed using univariate analysis, Spearman correlation test, and ordinal logistic regression with SPSS version 29.0. Higher viral load, lower CD4 count, and elevated NLR were significantly associated with poorer quality of life. In contrast, SGPT and eGFR were not significantly associated with quality of life. In the multivariate analysis, CD4 count showed the strongest association with quality-of-life category. These findings suggest that viral load, CD4 count, and NLR are associated with quality of life among HIV patients. The integration of virological, immunological, and inflammatory markers may complement clinical assessment of quality of life in people living with HIV, particularly in the Indonesian clinical setting. Further longitudinal studies are needed to clarify their predictive value.

Association of Environmental Sanitation and Personal Hygiene with Skin Health Complaints among Residents in Ibul Besar II
type: item
description: Skin health problems remain a common public concern, influenced by poor environmental sanitation and inadequate personal hygiene practices. Ibul Besar II Village is a suburban locale traversed by a tributary of the Ogan River. Data from the Pegayut Public Health Center in 2022 shows only 991 residents had access to proper sanitation. Moreover, of the 748 houses surveyed, only 284 were classified as healthy housing. In 2023, skin diseases ranked among the top ten most common illnesses at the Pegayut Public Health Center, with 115 cases reported. This study aimed to examine the association between environmental sanitation, personal hygiene, and skin complaints among residents of Ibul Besar II Village. Using a cross-sectional design with 142 respondents meeting the inclusion criteria, data were analyzed through univariate, bivariate (chi-square test), and multivariate (multiple logistic regression) methods. The bivariate results showed significant associations between skin complaints and factors such as bathing habits (p = 0.001; OR = 3.402; 95% CI: 1.670–6.931), hand and nail hygiene (p = 0.012; OR = 2.532; 95% CI: 1.276–5.027), clothing hygiene (p = 0.021; OR = 3.000; 95% CI: 1.240–7.255), bedding and bed linen hygiene (p = 0.011; OR = 2.548; 95% CI: 1.286–5.047), faeces disposal facilities (p = 0.011; OR = 2.919; 95% CI: 1.331–6.402), and wastewater disposal systems (p = 0.001; OR = 4.067; 95% CI: 1.804–9.167). Multivariate analysis showed that inadequate wastewater disposal systems had the strongest association with skin health complaints (p = 0.003; OR = 3.959; 95% CI: 1.605–9.758). To prevent skin health issues, priorities should include improving wastewater disposal facilities and promoting better hygiene of bedding and linen. Additionally, community members are encouraged to improve personal hygiene and maintain environmental sanitation to reduce the risk of skin disorders.

Association between Stunting Prevention Behaviors and Quality of Life among Adolescent Girls: A Cross-Sectional Study in Lebak District, Indonesia
type: item
description: Adolescent girls constitute a strategic group in the prevention of intergenerational stunting through the establishment of healthy lifestyle behaviours from an early age. However, evidence regarding the relationship between stunting prevention behaviours and quality of life remains limited. This study aims to analyse the relationship between stunting prevention behaviours and quality of life among adolescent girls in Lebak Regency, Indonesia. The study employed an observational analytical design using a cross-sectional approach involving 113 adolescent girls selected at random from a senior secondary school. Stunting prevention behaviours were measured using a health behaviour questionnaire, whilst quality of life was assessed based on the dimensions of satisfaction, productivity, independence and social participation. Analysis was performed using Kendall’s tau correlation test. The results showed a statistically significant positive association between stunting prevention behaviour and overall quality of life (r=0.349; p<0.001), as well as across all dimensions of quality of life (r=0.181–0.268; p<0.05), although the strength of the association ranged from weak to moderate. These findings suggest that adolescents with better stunting prevention behaviours tend to have a better quality of life. However, as a cross-sectional design was used in a single school, the study results cannot be used to draw conclusions about a cause-and-effect relationship. A longitudinal study that accounts for confounding factors is required to confirm these findings.

Development and Preliminary Clinical Validation of the Vitaltrack Early Warning Score Prototype for Integrated Inpatient Monitoring
type: item
description: Early detection of changes in patients' clinical conditions is very important to prevent critical events. The Early Warning Score (EWS) assessment still relies on conventional tools that require multiple devices and time, which reduces efficiency and accuracy. Objective: To develop and evaluate a portable vital sign measurement tool based on EWS (Vitaltrack EWS) to improve the speed and accuracy of assessments compared to conventional methods. Methods: The study used a Research and Development (R&D) design involving 39 inpatients in the neurology and surgery wards of RSUD Dr. Soedarso Pontianak. Five physiological parameters blood pressure, pulse rate, body temperature, respiratory rate, and oxygen saturation were measured using two methods: conventional tools and Vitaltrack EWS. A t test was used to assess the equivalence or differences in results between the two measurement methods. Results: EWS score p = 0.932, systolic blood pressure p = 0.907, body temperature p = 0.584, heart rate p = 0.487, respiratory rate p = 0.083, oxygen saturation p = 0.487, measurement time p = 0.000. Vitaltrack EWS is assessed to be accurate and efficient in monitoring patients' vital signs, comparable to the standard tools that have been used in hospitals. Conclusion: Vitaltrack EWS is capable of improving the efficiency and accuracy of vital sign measurements and supports the effective implementation of EWS in inpatient settings. Optimization of sensors and applications through further research provides a scientific basis for the feasibility of commercializing the tool.

Effectiveness of Virtual Reality-Based Health Promotion and Safety Training in Schools
type: item
description: Health and safety within the school environment are essential to ensuring a secure and sustainable learning process. Data from the Ministry of Health (2022) indicate that only 45% of secondary schools have an established emergency preparedness programme. A preliminary assessment at SMK Atisa Dipamkara also revealed substantial gaps: 73% of students had never participated in a fire simulation, and existing training remained conventional without interactive media. Nutritional issues were similarly prominent, as 60% of students frequently skipped breakfast, potentially impairing concentration and physical endurance. This study examined the effectiveness of a virtual reality (VR)-based training model integrating fire emergency simulation and balanced nutrition education. The study was conducted at SMK Atisa Dipamkara, Tangerang, from May to July 2025. A quasi-experimental design was employed involving 100 respondents assigned to VR and conventional training groups. Data were collected through knowledge tests, skills assessments, and Likert-scale satisfaction questionnaires. The findings demonstrate significant improvements in knowledge and skills among participants receiving VR training (p < 0.001), with outcomes superior to the conventional group. High satisfaction scores (M = 4.36; SD = 0.53) reflected strong perceptions of realism, interactivity, engagement, and active participation. VR-based training effectively addresses critical gaps in school preparedness and represents a strategic approach for strengthening comprehensive safety and health promotion programmes in educational settings.

Determinants of Pneumonia in Toddlers: Multivariate Analysis
type: item
description: Pneumonia remains a leading cause of morbidity and mortality among toddlers aged 12-59 months at Cikande Health Center Serang Regency, with 89 cases reported from January to March 2025. This unmatched case-control study included 118 toddlers (59 pneumonia cases and 59 healthy controls from nearby households, 1:1 ratio, purposive sampling). Pneumonia was defined as cough ≥2 days with rapid breathing or chest indrawing. Data on toddler gender, maternal education/knowledge, bedroom ventilation (≥10% floor area), humidity (40-60% RH), occupancy density (≤2 persons/room) and cigarette smoke exposure were analyzed via Chi-Square (bivariate) and multiple logistic regression (multivariate, stepwise elimination, interaction tests) using SPSS. Bivariate analysis showed significant associations (p < 0.05) for all factors. Multivariate modelling retained maternal education (pv=0.041, OR=2.606, 95% CI: 1.042-6.518), maternal knowledge (pv=0.003, OR=3.916, 95% CI: 1.580-9.708), bedroom ventilation (pv=0.026, OR=2.771, 95% CI: 1.126-6.818), bedroom humidity (pv=0.001, OR=5.360, 95% CI: 2.077-13.835) and occupancy density (pv=0.006, OR=3.676, 95% CI: 1.464-9.228). Bedroom humidity was the most dominant factor. No significant interactions found. Modifiable environmental factors (humidity, density) and maternal factors are key pneumonia determinants. Interventions should target home environmental improvements and maternal education.

Estimated Health Risk of Cadmium and Chromium in Elderly Blood Cockle Consumers, Lantebung
type: item
description: This study assessed the non-carcinogenic health risks of Cadmium (Cd) and Chromium (Cr) exposure through blood cockle (Anadara granosa) consumption among elderly residents in Lantebung, Makassar Strait. Blood cockle samples were collected from six purposively selected points, and Cd and Cr concentrations were analyzed. Health risks were estimated using intake calculations and the Risk Quotient (RQ). Cd and Cr concentrations were generally below national and international food safety limits. However, some elderly individuals, particularly frequent consumers, exceeded the non-carcinogenic risk threshold (RQ > 1). The highest risks were associated with specific sampling points, reflecting localized contamination. Risk factors included high consumption rates, long exposure duration, and lower body weight. These findings suggest that compliance with contaminant limits alone may not ensure safety for vulnerable populations. Regular environmental monitoring, risk communication for high-risk groups, and strengthened pollution control measures are recommended. Public health interventions, including periodic health screening and guidance on safe seafood consumption, are needed to reduce long-term health impacts.

Preliminary Study of Life Cycle Assessment on Food Surplus Redistribution Compared to Food Waste Management in Surabaya
type: item
description: Food waste accounts for approximately 40% of total waste generation in Indonesia and contributes significantly to national greenhouse gas (GHG) emissions. While most food waste is still disposed of in landfills, food surplus redistribution through food banks has emerged as a potential mitigation strategy. This study evaluates the environmental performance of food surplus redistribution compared to conventional food waste management options using a life cycle assessment (LCA) approach. The analysis was conducted at Garda Pangan, Surabaya, with a functional unit of 1 ton of food surplus and assessed three scenarios: (1) landfill disposal, (2) composting and anaerobic digestion, and (3) food surplus redistribution. The assessment applied the CML IA Baseline method and focused on Global Warming Potential (GWP), using SimaPro 9.0 and the Ecoinvent 3 database. The results show that landfill disposal has the highest GWP at 1,920 kg CO₂-eq per ton of food waste, driven primarily by methane emissions from anaerobic decomposition. Composting and anaerobic digestion result in lower impacts, at 1,503 and 1,730 kg CO₂-eq per ton, respectively. In contrast, food surplus redistribution shows a markedly lower GWP of 1.24 kg CO₂-eq per ton of food surplus, as emissions are dominated by transportation activities within a simplified gate-to-gate system boundary. This preliminary analysis relied on secondary inventory data and excluded potential avoided food production impacts; therefore, the estimated GWP for redistribution may underestimate or overestimate actual emissions. These findings highlight the importance of prioritizing food waste prevention and the benefits of food surplus redistribution within integrated waste management strategies to reduce GHG emissions while delivering social co-benefits.

Association Between Menopausal Status and Serum Uric Acid Levels Among Women in Southeast Pontianak
type: item
description: Serum uric acid levels are influenced by multiple factors, including hormonal status in women. Menopause, defined as the absence of menstruation for at least 12 consecutive months, is associated with decreased estrogen levels that may reduce renal uric acid excretion. However, local epidemiological data regarding uric acid profiles among menopausal women in Southeast Pontianak remain limited. This study aimed to analyze serum uric acid levels based on menopausal status among women in the working area of Puskesmas Kampung Bangka, Southeast Pontianak. A cross-sectional study was conducted using a purposive sampling technique. From a population of 230 women, 76 respondents met the inclusion criteria. Premenopausal women were defined as those with regular menstruation, while postmenopausal women were defined as those with amenorrhea ≥12 months based on interview data. Serum uric acid levels were measured using a spectrophotometric enzymatic colorimetric method and analyzed descriptively. The results showed that among 43 premenopausal women (56.6%), 97.7% had normal uric acid levels and 2.3% were below normal. Among 33 postmenopausal women, 75.8% had normal levels, 18.2% had elevated levels, and 6.0% were below normal. Elevated uric acid levels were more frequently observed in postmenopausal women compared to premenopausal women. In conclusion, although most respondents had normal serum uric acid levels, postmenopausal women showed a higher proportion of hyperuricemia, suggesting a potential influence of hormonal changes. This study provides important local evidence to support early metabolic risk screening among menopausal women in Southeast Pontianak.

This study aims to test the efficacy of Red Ginger Extract Nanoemulgel (RGE Nanoemulgel) as a new topical agent in controlling bacterial infections and accelerating the healing of experimentally induced infected incision wounds in a preclinical mouse model. The study comprised in vitro antibacterial and anti-biofilm activity assays comparing RGE Nanoemulsion against Gentamicin, followed by in vivo efficacy testing in an animal model comparing RGE Nanoemulgel, RGE, and Mupirocin in terms of bacterial abundance (log CFU/gram) and wound contraction percentage. Results indicated that RGE Nanoemulsion demonstrated promising in vitro antimicrobial activity; at a concentration of 25%, antibacterial inhibition reached 75.11% (exceeding Gentamicin at 51.18%), and anti-biofilm inhibition reached 90.79% at 50% concentration. In vivo, RGE Nanoemulgel suppressed bacterial abundance to 3.96 log CFU/gram, comparable to Mupirocin, and achieved a wound contraction rate of 93.50% on Day 12, exceeding Mupirocin (63.16%). These preclinical findings suggest that RGE Nanoemulgel may represent a promising non-antibiotic topical candidate, combining antibacterial, anti-biofilm, and wound-supportive properties. Further toxicity, stability, and clinical validation studies are warranted before therapeutic claims can be established.

Mosquito Larvae Identification in Water Storage and Assesment of Worker’s Knowledege, Attitudes, and Practices
type: item
description: Vector-borne diseases remain a major public health concern in tropical regions, with dengue fever continuing to be the predominant vector-borne disease in urban Indonesia. Public tourist areas with high human activity may provide favorable breeding sites, making sanitation workers’ roles crucial. This study aimed to identify mosquito breeding characteristics and larval presence in water-holding containers (WHCs) and to describe the knowledge, attitudes, and practices (KAP) of sanitation workers in a historic public open space in an urban setting. A descriptive cross-sectional study using a mixed-methods approach was conducted, combining quantitative entomological surveys with qualitative in-depth interviews. All accessible WHCs at the study site were inspected for larvae, which were collected and morphologically identified, and Aedes larval indices (ABJ/Angka Bebas Jentik, HI, CI) were calculated. Sanitation workers were selected purposively as qualitative informants, and KAP data were analyzed thematically. Seven WHCs were identified, of which two outdoor natural pools (28.57%) were positive for larvae, yielding 13 larvae, all identified as Culex spp., with no Aedes spp. detected. Consequently, Aedes-specific indices showed an ABJ of 100%, HI of 0%, and CI of 0%, indicating a low risk of dengue transmission according to WHO criteria (HI <4% and CI <3%). Sanitation workers demonstrated generally good knowledge, positive attitudes, and routine preventive practices, although understanding of the full 3M Plus concept varied. In conclusion, despite the presence of non-Aedes larvae in outdoor natural containers, the absence of Aedes breeding sites suggests effective dengue vector control supported by routine sanitation practices in the study area.

The Effectiveness of Rice Straw and Cogongrass Straw Soaked Water Attractants on the Number of Aedes spp. Mosquitoes
type: item
description: Aedes spp. mosquitoes are the main vectors of Dengue Hemorrhagic Fever (DHF), which remains a public health problem in Indonesia. Chemical insecticide-based mosquito control has the potential to cause environmental pollution and vector resistance, so safer and more environmentally friendly control alternatives are needed. This study aimed to analyze the effectiveness of rice straw and cogongrass straw-soaked water attractants in attracting Aedes spp. mosquitoes. Method this study used a pure experimental design with a post-test only control group design. The study was conducted at Muhammadiyah Ahmad Dahlan University, Palembang. Traps were placed purposively with a total of 27 observation units consisting of three treatment groups, namely control (water without attractant), rice straw-soaked water attractant, and cogongrass straw-soaked water attractant, each with nine replications. Traps were set for 5–7 days. Data were analyzed using the Shapiro–Wilk normality test, homogeneity test, One Way ANOVA, and the Least Significant Difference (LSD) test with a significance level of 0.05. The results showed the total number of mosquitoes trapped in the control group was 16, in the rice straw attractant group was 31, and in the cogongrass straw attractant group was 32. The average number of mosquitoes in the control group was 2.00 ± 0.67, in the rice straw group was 3.00 ± 1.13, and in the cogongrass straw group was 4.00 ± 1.13. The results of the One- Way ANOVAanalysis showed a significant difference between the treatment groups (p = 0.01). Further LSD tests showed that both attractant groups were significantly different from the control, but there was no significant difference between the rice straw and cogongrass straw attractants. These findings indicate soaked water from rice straw and cogongrass straw was effective in increasing the number of trapped mosquitoes compared to the controlas a natural attractant to catch Aedes spp. mosquitoes and has the potential to be an…

Predictive Value of Neutrophil-to-Limphocyte Ratio for Detecting Nonalcoholic Fatty Liver Disease in Type 2 Diabetes Mellitus Patients
type: item
description: Type 2 diabetes mellitus (T2DM) is a chronic metabolic condition characterized by insulin resistance, leading to increased blood glucose levels (hyperglycemia). Insulin resistance is a key factor in the development of nonalcoholic fatty liver disease (NAFLD), a condition defined by excessive hepatic fat accumulation that is not caused by alcohol consumption. NAFLD can progress from simple steatosis to hepatic inflammation and fibrosis. The neutrophil-to-lymphocyte ratio (NLR) is a simple biomarker for systemic inflammation. Elevated NLR values may indicate increased inflammation, such as that observed in NAFLD. This study aimed to determine differences in NLR values in T2DM patients with NAFLD and without NAFLD. This cross-sectional study used secondary data from the medical records of 88 T2DM patients from 2022 to 2024, divided into groups without NAFLD (n=45) and with NAFLD (n=43) based on ultrasonographic liver findings. The Welch t-test was applied to compare NLR values, and receiver operating characteristic (ROC) analysis was used to identify the optimal cut-off value for NLR. The NAFLD group had significantly higher NLR values (mean difference = 3.80; 95% CI: 2.75–5.24; p<0.001), with an AUC of 0.962 (95% CI: 0.915–1.000; p<0.001) and an optimal cut-off value of ≥3.1964 (sensitivity 90.7%; specificity 100%). In conclusion, NLR is significantly elevated in T2DM patients with NAFLD and demonstrates strong discriminatory ability, indicating its potential use as a simple inflammatory biomarker in T2DM managements.

Correlation Between TNF-α Levels and APRI Score with Ejection in Hepatic Cirrhosis
type: item
description: Cirrhotic cardiomyopathy is a condition of heart dysfunction characterized by impaired myocardial contractility, left ventricular hypertrophy, diastolic dysfunction, chronotropic dysfunction, and electrophysiological disturbances of the heart. One of the complications in patients with hepatic cirrhosis is influenced by several factors, particularly TNF-α levels and the APRI score. This study aimed to analyze the effect of TNF-α and APRI score on ejection fraction in Child-Pugh C hepatic cirrhosis. Methods: This study employed an analytical observational design with a cross-sectional approach. The sample consisted of 40 inpatients with Child-Pugh C hepatic cirrhosis at the dr. Moewardi Surakarta Regional General Hospital. Samples were selected using consecutive sampling. Data analysis was performed using Spearman’s correlation test and linear regression. Results: The correlation between TNF-α levels and ejection fraction in Child-Pugh C hepatic cirrhosis is r = -0.559, p<0.001 (moderate correlation). The correlation between APRI score and ejection fraction in Child-Pugh C hepatic cirrhosis is r = -0.445, p<0.001 (moderate correlation). There is a significant correlation between TNF-α levels and APRI score with ejection fraction in Child-Pugh C hepatic cirrhosis. The implication is that clinicians may incorporate TNF-α levels and the APRI score into clinical algorithms to monitor cirrhotic patients who are at high risk of developing cardiovascular complications.
