Municipal solid waste (MSW) production continues to rise globally, especially in developing countries such as Indonesia, creating significant environmental challenges. This study investigates the impact of moisture content (MC) variation on ammonia (NH₃) and hydrogen sulfide (H₂S) emissions during the MSW drying process, and evaluates the effectiveness of a gas capture system using waste motor oil (WMO). Laboratory-scale experiments were conducted at Universitas Pendidikan Nasional in collaboration with Universitas Udayana, using MSW samples conditioned at five moisture levels: 50%, 40%, 30%, 20%, and 10%. Emissions were measured before and after treatment with the WMO-based interceptor system. The results showed that the highest gas emissions occurred at 50% MC, with corresponding reduction efficiencies of 73.9% (50% MC), 70.0% (40%), 72.1% (30%), 55.9% (20%), and 5.4% (10%). Higher MC was associated with increased anaerobic microbial activity and organic matter decomposition, leading to elevated NH₃ and H₂S generation. The WMO system demonstrated strong gas adsorption performance, particularly at moderate to high MC levels. These findings suggest that controlling MC and applying low-cost WMO-based gas interception can significantly reduce emissions in waste drying processes. This approach holds promise for improving air quality in urban waste management systems, especially in resource-limited settings.

The community service activity which was carried out in the Panjer Traditional Village, Denpasar aims to help overcome flooding in the Panjer Traditional Village area by installing hundreds of biopore holes. Biopores are small holes made at the surface of the soil with the aim of increasing the soil's absorption of rainwater. This method was first developed by Dr. Kamir R. Brata from the Bogor Agricultural University (IPB) as a solution to overcome the problem of waterlogging and urban flooding. Biopore holes are made using special tools to drill the soil to a certain depth, usually filled with organic matter such as leaves or food scraps. This organic matter will then be broken down by soil microorganisms, creating empty spaces that increase soil porosity. The activity was carried out simultaneously with hundreds of students and lecturers of the Faculty of Engineering and Informatics, Universitas Pendidikan Nasional. There are 14 groups divided into this biopore hole installation activity. The installation locations are spread across several points starting from the Waturenggong Street area to the end of Jalan Tukad Yeh Aya. The main function of biopores is to increase the absorption of groundwater, so that it can help reduce the risk of flooding and waterlogging. In addition, biopores also function to improve soil structure and increase soil fertility by adding organic matter. Another benefit of biopores is that it helps the process of recycling organic waste into compost that is beneficial to plants.
