Abstract

Universitas Pembangunan Nasional “Veteran” Jawa Timur is one of the public facilities that produces solid waste, including organic waste, inorganic, and hazardous waste. Waste that can be immediately utilized is organic waste consisting of food waste and leaves and twigs. Therefore, appropriate technology is needed to process organic waste into more useful goods and as a better management alternative through community service. One of the alternatives for processing waste is recycling it into compost using Simultaneous Composting Technology with EM4 and MOL. The main target of this community service is to reduce waste and utilize university waste with appropriate technology for regional coverage and national coverage in the future. The method of this community service is to separate waste between organic and non-organic, selected organic waste is cut by a hammer mill, and then other waste from the canteen activity is made Local Microorganisms (MOLs) as the decaying medium in the composite production of the organic garbage processing device reactor. As a result, this community service has been running smoothly and well. The results of this community service have a positive impact through the use of organic waste into compost which can be utilized by the internal campus and generate economic value.

Abstract

Aluminum is an inorganic material that cannot be decomposed naturally in nature, while its presence in our lives is very abundant and quite crucial. One of its uses is as a raw material for food or drink cans. In the United States alone in 2012 around 38.2 billion cans of food or drink were produced. Therefore, efforts are needed to reduce aluminum waste. One use that can be made is by extracting the aluminum content in it to be used as raw material for alum coagulants and PAC. The aluminum that has been successfully extracted is then added with solutions that can cause polymerization and form alum and PAC coagulants. Next, the resulting synthetic coagulant was tested for its ability to reduce turbidity in laundry waste. Laundry waste itself was chosen because the waste processing is still simple, and generally, this type of waste contains suspended solids which can come from dirt attached to clothes or chemicals used in detergents. In this study, coagulation and flocculation were carried out with 500 mL of laundry waste sample taken and a synthetic coagulant dose of 100 PPM. After the coagulation-flocculation process was carried out, the sample was deposited with varying settling times of 30 minutes, 60 minutes, and 90 minutes. From the results of this research, it was found that synthetic PAC coagulant was more effective than alum in reducing turbidity in laundry waste. At the most effective deposition time, namely a deposition time variation of 30 minutes, the removal percentage was 57%.

Abstract

This study aims to analyze the influence of OHS knowledge, OHS attitude, workload, and work fatigue on the incidence of work accidents in Bogor Regency hospitals. The method used was multiple linear regression, with data collection through questionnaires distributed to doctors and nurses. The results of the analysis showed that OHS knowledge, workload, and work fatigue had a significant influence on occupational accidents, while OHS attitude did not show a significant impact. The significance value in the F test was recorded at 0.000, indicating a strong relationship between the independent variables and occupational accidents. The coefficient of determination (R²) of 0.864 indicates that 86.4% of the variation in work accidents can be explained by these variables. The findings suggest the importance of improving OHS knowledge and managing workload and fatigue to reduce the incidence of occupational accidents in hospitals. The implications of this study can serve as a basis for hospital management in designing more effective safety programs and encouraging a safety culture in the work environment. This study emphasizes the need for more attention to managing workload and fatigue to improve the occupational safety and health of medical personnel.

Abstract

Effective and efficient water treatment is needed to improve water quality. The content of iron (Fe) and manganese (Mn) compounds in water is a major problem that can affect health and interfere with human activities. One of the steps that can be taken to degrade manganese is oxidation using aeration. In this study, variations in the diameter of venturi aerators were used to determine the performance of venturi aeration in water treatment. The variation in diameter was set at 12mm, 10mm and 8mm sizes. Based on the results of the study, dissolved oxygen levels have increased over time. The highest increase in dissolved oxygen content was achieved with the 12 mm diameter variation with dissolved oxygen levels reaching 7.8 mg/litre within 60 minutes. a significant reduction in iron content of 92% with an iron content of less than 0.0567 mg/litre. The largest percentage decrease in manganese content occurred with the variation of the aerator vent hole diameter of 12 mm, which was 54% with an aeration time of 15 minutes. There is a fluctuation in the decrease in manganese content caused by the more difficult to oxidise properties of manganese.

Abstract

This study focuses on the pollution of the Gude Ploso River in Jombang Regency, East Java Province, Indonesia, mainly caused by household and tofu industry waste. To control pollution, it is crucial to identify pollution sources, predict changes in water quality, and test the effectiveness of mitigation strategies. Our results show that several parameters in the Gude Ploso River exceed permissible limits, including total suspended solids (TSS), phosphate, and chemical oxygen demand (COD). Pollutant carrying capacity calculations indicate that phosphate and COD levels exceed the maximum carrying capacity at all sampling sites. Analysis using the STORET method indicates moderate levels of pollution with values of -30, -20, -21, and -21. Proposed mitigation strategies include monthly or quarterly monitoring of factories near the Gude Ploso River, conducting outreach and workshops for local communities to raise awareness about the state of the river, implementing phytoremediation at various points along the river, establishing environmental NGOs in the area, and conducting water flushing during dry periods. These strategies aim to reduce pollution in the Gude Ploso River, ensure the sustainability of its ecosystem, and provide a decent quality of life for the communities that rely on the river as a water resource.

Abstract

Polluted groundwater can be treated using tray aerator technology, particularly to reduce the concentration of iron (Fe) and manganese (Mn) in well water, especially in the Jombang area. This technology uses oxidation by introducing air through a tray aerator, which has variations in hole diameter and distance between trays. The study focused on the effect of variations in tray hole diameter (0.4 cm, 0.5 cm, 0.6 cm) and contact time on improving water quality. Activated carbon was also added as a medium to help adsorb pollutants. The results showed that tray aerators with the right diameter and spacing can significantly reduce Fe and Mn levels to meet drinking water quality standards according to government regulations. Parameters such as dissolved oxygen (DO), pH, temperature and Fe and Mn concentrations were measured periodically to evaluate the effectiveness of the aerator. This study is an important contribution to the development of more efficient and environmentally friendly water treatment technology.

Abstract

In the well water of Sengon Village, the levels of Fe (iron) and Mn (manganese) exceed the established quality standards of 0.743 mg/L and 1.60 mg/L respectively. One of the treatment solutions to reduce these contaminant levels is the aeration method of the aeration tray with the addition of media. The aeration method works by bringing water into contact with oxygen. The aim of this study is to determine the optimum performance of tray aerators by comparing the addition of activated carbon, zeolite or mixed media. Each media has an influence on the measurement results of pollutant levels in units of percent removal. The parameter with the highest weight is the one that most influences the effectiveness in removing Fe and Mn. The values of the parameter variations were then analysed and Anova Two Way statistical test was performed. The results showed that the most optimal reduction of Fe levels was achieved by aeration with activated carbon media with an aeration time of 150 minutes with a percentage removal of 96.67% and a level of 0.0234 mg/L. To reduce Mn levels, the most optimal aeration with addition of zeolite media with an aeration time of 150 minutes with a percent removal of 99.08% and levels <0.0145 mg/L. And to increase DO levels, the most optimal is aeration with the addition of activated carbon media with an aeration time of 150 minutes and a final DO value of 6 mg/L.
