Abstract

Leachate pollution resulting from dissolution process organic and inorganic materials in open landfills is a serious environmental problem. Leachate contains various pollutants, such as heavy metals, organic compounds, and hazardous compounds that can damage water and soil quality not managed properly. This study aims assess the effectiveness activated carbon in reducing pollutants in leachate and factors that affect the performance of activated carbon in leachate treatment. The method used in study is leachate treatment using activated carbon as an adsorbent medium. Testing was carried out with variations in contact time and activated carbon concentration to determine the optimal conditions for pollutant absorption. Water quality parameters tested included COD, BOD, Fe and Zn. The results of  study showed that activated carbon is very effective in reducing pollutant content in leachate. This can be seen from results of the effectiveness calculation where it was found that activated carbon can reduce COD 63.96%, BOD 44.89%, Fe 83.33%, and Zn 83.33%.

Abstract

The problem of household organic waste remains an environmental issue that requires effective management in various regions, including Jelu Village. This community service activity aims to increase active community participation in organic waste management through the use of Black Soldier Fly (BSF) larvae. BSF cultivation technology was chosen because it can quickly decompose organic waste and produce by-products in the form of animal feed and organic fertilizer. This program was implemented through an educational approach, technical training, and direct mentoring for residents from several neighborhood units (RT) in Jelu Village. The results of the activity showed an increase in community knowledge and skills in BSF cultivation, with maggot production reaching 2 kg in three weeks and daily organic waste management of around 4–5 kg. Furthermore, the community was also able to independently build cultivation cages. This activity has succeeded in raising ecological awareness while providing economic benefits, and is expected to become a model for sustainable organic waste management at the village level.
