Abstract

Green Village (KRL) is one of the programs to realize Bogor Green and Clean Regency. KRL Berani Asri RW 15 Cileungsi Kidul was formed to carry out the production, management and utilization independently. Has several problems such as environmentally friendly awareness, not yet optimal waste management, the economic potential of organic and non-organic waste. P2M Mechanical Engineering Study Program IT PLN aims to provide alternative solutions so that KRL Berani Asri is independent in waste management. The method of implementation is socialization, training on waste management, composting, and making plastic chopper machines. The results of the P2M are 67.8% of resident have knowledge about waste management, 61.7% have good waste management behaviour, and 53.8% of residents say that KRL Berani Asri does not yet have waste management infrastructure. The use of appropriate technology has an impact on increasing compost production from 50 bags to 200 bags per week, and the production of plastic that has been sold from 10 kg to 100 kg per week

Abstract

Incineration is a key waste treatment technology in the pursuit of sustainable solutions, and the use of biomass as an alternative fuel either alone or mixed offers a pathway to improve combustion efficiency. This study explores how woodchips and municipal solid waste (MSW) behave during combustion when used individually and in mixed-fuel configuration laboratory scale conditions. Fuel characteristics were determined through proximate and ultimate analyses following ASTM standards. Combustion performance was assessed using temperature profiles, burning rates, the amounts of char and ash produced. The results show combustion behavior among the tested fuels. Woodchips demonstrated the most stable combustion, with the highest heating value 4,134 kcal/ kg, the lowest ash content of 0.91%, and peak temperatures reaching 1,095 °C. In contrast, MSW burned less consistently, producing lower peak temperatures between 913 °C and 992 °C, higher char yields of up to 3%, and ash contents exceeding 13%. When woodchips were mixed with MSW, combustion performance improved noticeably. Among the tested mixtures, the 75:25 woodchips:MSW ratio provided the most balanced results, achieving a peak temperature of 1,069.2 °C, char yields of 1.7–1.8%, and ash content of ash yield below ~6.5%, while maintaining stable combustion conditions. Elemental analysis further indicated that woodchips contained very low sulfur 0.06% and also nitrogen 0.05%, suggesting lower potential for emission formation. Mixed woodchips:MSW at a 75:25 ratio substantially reduced sulfur and nitrogen contents compared to pure MSW. Overall, these findings indicate that a 75:25 woodchip:MSW mixture offers a practical balance between combustion stability, residue reduction, and emission formation potential for small scale waste to energy applications.
