Analisis Potensi Implementasi Bank Sampah sebagai Upaya Optimalisasi Pengelolaan Sampah di Universitas Sumatera Utara

Abstract

Medan City is targeting a 30% reduction in waste and 70% waste management by 2025. However, in 2023, waste generation reached 645,661.28 tons with a sorting rate of only 13%, requiring a strategy to increase sorting through active community participation, one of which is through waste banks. The University of North Sumatra (USU) has great potential for sustainable waste management due to its strategic location and the presence of an Integrated Waste Processing Facility (TPST). This study analyzes the potential for establishing a waste bank at USU from the perspective of prospective customers, prospective managers, the economic value of waste and the purchase price of waste, as well as indicators of PermenLHK No. 14/2021 using a quantitative and qualitative approach through a questionnaire of 100 respondents, interviews, observations, and analysis of the economic value of waste. The results show that 88% of potential customers are willing to participate, the majority of whom are students, employees, and the surrounding community, with good knowledge and attitudes towards waste management (63%–77% and 71%–77%), although waste management behavior is still low (20% 52%). The potential waste that can be collected reaches 402.6 kg/week (15%) from households and 2,320 kg/week (85%) from outside households, predominantly organic, paper, and plastic bottles, with high interest in the savings system and an 85:15 profit sharing scheme. The operation of the waste bank requires 7–8 managers for 6 positions, with some core positions being open to students. The purchase price of waste under various schemes is able to cover operational costs and provide the highest profit under the BSI Sicanang Scenario II strategy, with profits reaching IDR 537,132. The TPST capacity is only 4.2% and 7.2% of the total TPST capacity, and an investment of IDR 154–171 million is required. Based on Permen LHK No. 14/2021, the potential for establishing a waste bank is classified as good (score of 26.6), although participation in sorting five types of waste is still low. Therefore, the implementation of a waste bank at the University of North Sumatra has great potential in terms of customer availability, waste bank managers, economic value, and is in line with the assessment of Ministry of Environment and Forestry Regulation No. 14/2021.
