Abstract

The Dharma Bakti Waste Bank in RT. 55, Muara Rapak Subdistrict, is one of the waste banks that remains active in managing community waste. However, the utilization of organic waste is still limited to compost production, while alternative management methods, such as Black Soldier Fly (BSF) maggot cultivation, have not been optimized. This community service program aims to enhance the utilization of organic waste through BSF maggot cultivation as an alternative feed for livestock, particularly catfish, which are already being farmed by residents. The method used in this program began with an awareness session on the benefits of maggot cultivation, followed by the construction of BSF fly cages, as well as hands-on training and practice on cultivation techniques for residents. The evaluation was conducted by measuring the increase in residents’ understanding before and after the training, along with a community satisfaction survey regarding the activities carried out. The results indicate a 17.98% increase in residents' understanding of BSF maggot cultivation, reflecting the effectiveness of the education and training provided. Additionally, the community satisfaction survey showed that 90% of residents were very satisfied, while the remaining 10% were satisfied. This initiative concludes that, in addition to providing valuable learning experiences for residents, it also empowers them in maggot cultivation through education and training, enabling better optimization of organic waste processing into economically valuable resources.

Abstract

Balikpapan City, as one of the supporting cities for the Nusantara Capital City (IKN) in East Kalimantan, faces significant challenges in meeting the demand for clean water. The increase in population due to migration and infrastructure development following the relocation of the IKN has led to a continuous rise in the demand for clean water. The rate of water loss, or Non-Revenue Water (NRW), is quite high, reaching 25.85%. This situation has resulted in low distribution efficiency and highlights a gap between the available clean water distribution system and the actual needs of the community. As a result, clean water service coverage reached only 80.07% in 2022. This study aims to identify the factors influencing clean water distribution, develop a dynamic system model, and formulate optimal scenarios. The research method used is a dynamic systems approach, which enables comprehensive analysis of the cause-and-effect relationships between variables in the clean water distribution system, as well as simulation of various policy scenarios to find the most effective and sustainable solutions. Simulation results show significant dynamics in clean water distribution. From 2023 to 2035, pipeline length increased from 1.4 million meters to 1.6 million meters, yet clean water consumption decreased to 23.67 million m³ in 2029 and 23.15 million m³ in 2035. Of the three designed scenarios, Scenario 3, which involves a 4.2% annual increase in pipeline repair rates and a 1.47% annual increase in the number of customers, proved to be the most effective. This scenario successfully reduces pipeline leakage rates and significantly improves distribution coverage.
