EDUCATION ZEROS OUT SOD: UTILIZATION OF STACKED BUCKETS FOR ORGANIC WASTEPROCESSING BY P4S BIROWO ORGANIK

Abstract

Indonesia is the 10th largest contributor of waste in the world (Ahdiat, 2023). Population growth is one of the causes of the increasing volume of waste. In addition, people's consumptive lifestyles to meet daily needs also result in high volumes of waste produced, especially organic waste. In Indonesia, the potential for additional organic waste is around 175 tons per day (Anonymous, 2022). Various efforts to deal with waste have been made, including the construction of TPS 3R (Reduce Reuse, Recycle Waste Management Site) and Waste Bank. However, in reality, efforts so far have only moved the problem.
Ngawi as one of the regencies in Indonesia also experienced the same thing. Organic Waste Piles, especially from the kitchen 2.16 kg/day (Djiha et al., 2021). The waste management units built in Ngawi Regency are 82 Waste Banks and 12 TPS 3R (Anonymous, 2024). However, these units have not been able to handle waste in Ngawi because it is not balanced with the volume of waste produced by the community. Therefore, various efforts have been made by all levels to overcome this problem, including those carried out by P4S Birowo Organik, namely by educating ZERO Kitchen Organic Waste (SOD) with the Stacked Bucket method in Ngawi Regency. The stacked bucket method is a technology created by Prof. Nasih Widya Yuwono, SP, MP (2018) by utilizing Black Soldier Fly (BSF) larvae (maggots). The Stacked Bucket method has been widely used on a household scale because it is easy to make, cheap, and easy to use.
