A System Dynamics Approach for Organic Waste Management in Traditional Market

Abstract

Waste that is not appropriately managed becomes worthless and hurts the surrounding environment. The Tempel market in Selman became a waste collection point for markets around Selman when the Piyungan landfill was closed. Waste management helps reduce waste accumulation and turn worthless waste into more valuable. A waste management design proposal to mitigate negative impacts and maximize land utilization was made in this study. A dynamic system approach was taken to assist decision-making. Many factors make waste generation dynamic and complex, so a dynamic system approach can make it easier to help make better decisions. Waste reduction focuses on organic waste. BSF larvae can reduce organic waste by 320,000 kg over the next five years. Waste reduction using BSF larvae also allows worthless waste to be converted into something new and valuable. The BSF larvae can be sold for animal feed, and the compost fertilizer from the larval bed can also be sold. Calculating the payback period for implementing waste management improvements using BSF larvae takes 11 months to pay back. In less than a year, this waste management project can return the capital spent for the first time by the manager, so the business implementation for this management is feasible.
