Abstract

Organic waste is the largest component of waste generation in Indonesia, with households as the main contributor. Data from the National Waste Management Information System (SIPSN) show that national waste generation reaches 30 million tons/year, of which 51.84% is organic waste. Sidoarjo Regency produces 320,690 tons/year, with an organic waste composition of 71.7%. The Integrated Waste Treatment Facility (TPST) in Tambakrejo Area, Waru District, serves 92,001 residents with a land area of 400 m² and an ideal capacity of 15 tons/day. The average incoming waste reaches 15,230 kg/day, causing overload conditions and indicating the absence of significant organic waste treatment. This study aims to determine the most effective household organic waste treatment scenario to minimize organic waste generation at TPST Tambakrejo Area. The study applies system dynamics modelling using Vensim PLE software through the development of a Causal Loop Diagram, Stock Flow Diagram, mathematical formulation, verification, and validation using the percent error in the means (E1) test. The model was declared valid, with an average error of 0.2%. Simulation results show that under Scenario 0, the Stock (Level) value increased from 3,311,100 kg in 2025 to 3,564,670 kg in 2030. Scenario 3, combining 20% composting and 35% Black Soldier Fly (BSF) treatment, resulted in a Stock (Level) value of 2,151,730 kg in 2030. Scenario 3 was selected as the most effective scenario, achieving a 39.64% red
