The world is currently facing significant environmental challenges due to increasing urbanization and globalization. Human activities can produce greenhouse gases (GHGs) such as CO2 and CH4. One of the contributors to GHG generation is the open dumping of Municipal Solid Waste (MSW), particularly because much of the waste is organic. It undergoes anaerobic decomposition, leading to the formation of GHGs, particularly methane. However, CH4 has a high potential for energy generation, and if harnessed properly, it can be highly beneficial. This study aims to assess the total air pollutants emitted from the landfill gas (LFG), including methane (CH4), carbon dioxide (CO2), and nonmethane organic compounds (NMOC) at the Regional Piyungan landfill in D.I. Yogyakarta province. The study also projected the year when the production of these gaseous pollutants would peak and when they are expected to be exhausted. Additionally, the study aimed to identify the potential health problems and clinical codification caused by these gaseous pollutants. To achieve these objectives, the LandGEM 3.03 version of the model developed by USEPA was used for the period 2023-2071. Clinical coding used the 2019 version of the ICD-10 reference. The estimated values for total LFG were 1.648E+04 (2024) and 1.584E+04 (2025) Mg/year, while CH4 was estimated at 4.403E+03 (2024) and 4.230E+03 (2025) Mg/year. CO2 was estimated to be 1,208E+04 (2024) and 1,161E+04 (2025) Mg/year, and NMOC was projected at 2,839E+01 (2024) and 2,727E+01 (2025) Mg/year. Some of the toxic effects that can occur cause respiratory, visual, and mental disorders with a variety of clinical codes.

Introduction: This study reviewed the negative impacts of artisanal small-scale gold mining (ASGM). This paper presents an examination of ASGM’s impact on health, with the scope of discussion covering human diseases and disorders, toxic substances, public and miners’ safety, environmental damage, socioeconomic conditions. This study contributes mitigation recommendations for ASGM in Indonesia. This research subject is important because there has not been an ASGM study that has reviewed these aspects in Indonesia. Discussion: Chronic diseases, acute diseases, infectious diseases, and disabilities can threaten local communities’ health and survival. Toxic heavy metals such as mercury, cadmium, arsenic, and lead are difficult to avoid in ASGM, since they have a high level of use. Other pollutants generated by ASGM are noise and silicia dust. ASGM has caused accidents with a total of 36 minor injuries, an estimated 57 serious injuries, and 11 deaths. ASGM also causes water, soil, and air pollution; it is a threat to the geology of world heritage sites. ASGM has been proven to improve the community's economy in several parts of Indonesia. Conclusion: ASGM has proven to have a significant impact on public health, environmental sustainability, and the socioeconomic state of Indonesian society. In general, the lack of ASGM legitimization in Indonesia is an enabling factor for these impacts.

Urban planning management should consider wastewater as a challenge. Wastewater, in this case, grey water, is full of dangerous contaminants and, at specific concentrations, can turn into a substance that affects the en - vironment. The effluent of the released waste must therefore be managed to ensure that it complies with the government’s quality standard criteria. The membrane bioreactor (MBR) technology process produced waste effluents with low concentrations of biological oxygen demand (BOD 5 ), chemical oxygen demand (COD), and total organic carbon (TOC), proving its higher efficiency as a biological processing stage. Total coliforms and E. coli are not present in processed products, detergents and total suspended solid (TSS) are effectively degraded. This is made possible by the considerably lower organic load; as a result, biomass accumulation slows and mixed liquor suspended solids (MLSS), which have low value, are produced. With the assistance of continuous airflow, and without the use of chemicals or backwashing, an ultrafiltration module (UF) with a membrane cut-off size small enough to be able to create a constant permeate flux during the grey water treatment process is necessary. Although processed grey water does not pass denitrification, all parameters linked to the quality of the effluent water exceed environmental quality criteria.

Purpose: The purpose of this research is to analyze the drinking water needs and raw water availability of DKI Jakarta Province. Theoretical framework: The theoretical basis for the population projections uses mathematical modeling (arithmetic, logarithmic, exponential, and geometric) for the next 10 years. Drinking water demand projections are obtained by calculating the demand for drinking water and the results of the population projections. Then compared to raw water availability. Potable water demands are calculated based on design criteria Method/design/approach: The method used is research and development by projecting the population of the last 10 years to predict the population of the next 10 years. The total projected drinking water needs obtained were compared with the availability of raw water. Results and conclusion: The results show that the demand for drinking water in DKI Jakarta in 2023 will be 30,892 liters/second, while the raw water capacity will only be 16,850. This shows that the level of drinking water service in DKI Jakarta is only 54.54%. When compared to 2015, DKI Jakarta's drinking water access service decreased from 65.13% in 2015 to 54.54% in 2023. Research implications: If DKI Jakarta does not succeed in finding raw water sources, it is estimated that drinking water services will drop dramatically to 35.68% in 2033. Originality/value: Studies on the projection of drinking water in DKI Jakarta, Indonesia for the next 10 years have not been conducted. So this study has good originality and becomes a study with high novelty. This study can also be utilized by DKI Jakarta government authorities in formulating environmental and health management policies.

Introduction: Hypertension is a manifestation of hemodynamic imbalances resulting in various cardiovascular complications and others in the body systems. The prevalence of hypertension in Indonesian adults aged 18 years was 34.1%, and it increased by 8.3%. Globally, it accounts for about 60% of deaths. This study aimed to analyze risk factors for hypertension in industrial workers. Methods: This study used a meta-analysis, a statistical method that combines previous studies to find an effect size value or summary on JASP software. Data in this study came from database online and were sorted according to the inclusion-exclusion criteria following PRISMA. In the final step, 14 research articles were collected. Results and Discussion: Noise intensity had a 1.974 times greater risk on the prevalence of hypertension in industrial workers; work period had 2.316 times greater risk; duration of exposure gave a 1.716 times greater risk; and smoking had a 1.896 times greater risk. Conclusion: The highest risks for the incidence of hypertension in industrial workers come from period of work, noise intensity, and smoking habits; while, the lowest is in the length of exposure

Introduction: The Padang City Health Office reported 9,452 diarrhea cases in 2019, 2,248 in toddlers. The Pauh District reported 413 diarrhea cases, 110 of which occurred in toddlers. Spatial analysis was used to assess environmental sanitation as determinant of toddlers’ diarrhea incidence in Pauh District, Padang City. Methods: This observational study used a cross-sectional approach. The population was 4,653 toddlers, and the sample was 100 toddlers. The independent variables in this study include environmental sanitation factors such as the quality of clean water (presence of Escherichia coli), the condition and quality of the waste container, the quality and condition of sewerage, and the density of flies in the trash and household sewerage. The spatial analysis used was Moran Index I to examine the distribution pattern of variables. Results and Discussion: The incidence of diarrhea in toddlers, unstandardized household waste containers, unqualified waste sewerage, high fly density in household trash bins, and high fly density in sewerage was randomly distributed with a Moran index consecutively -0.130524; 0.315524; 0.153129; -0.174424; -0.025798. Then, clean water quality, waste management, and sewerage conditions that did not meet the requirements were randomly distributed with a Moran index of -0.158512; -0.160688; -0.117502. Conclusion: The spatial pattern of environmental sanitation factors as determinants of the incidence of diarrhea in toddlers was randomly distributed, and there was no autocorrelation found among the villages in Pauh District.

Abstract Pesticide residue in food has been investigated since the growing demand of food safe. The determination of pesticides residues in food is becomes an essential requirement for consumers, producers, and authorities responsible for food quality control. Pesticides can poison humans through the mouth, skin, and breathing. Often unwittingly these toxic chemicals enter a person’s body without causing sudden pain and causing chronic poisoning. This study aimed to investigate the impact of pesticides residue to health problems from meta-synthesize, sourced from the Scopus and Sinta indexed articles and obtained 12 indexed articles that were used as references. Meta-synthesize result showed that there are some type of pesticide who used by farmers such as chlorphenapir, emamctin benzoate, abamectin, chlorpyrifos, mankozeb, chlorotalonil, and propineb. Continous use of pesticides can cause such as fatigue, excessive saliva, hard breathing, frequent urination, blurred vision, dizzinesss, and fingerpain. At the end, pesticides residue is adverse effect on human health problems.
