Optimalisasi Bank Sampah menuju Zero Waste dengan Prinsip Ekonomi Sirkular (Studi Kasus: Bank Sampah Induk di Provinsi Riau)

Abstract

Waste bank is a community-based waste management with the 3R principle and one of the applications of circular economy. However, there are still waste banks that have not optimally helped in reducing waste due to various factors. The purpose of this research is to analyze the material balance and recovery factor of waste banks, to determine the development strategy of waste banks with SWOT analysis, to determine the application of circular economy in waste banks, and to plan recommendations and strategies for optimizing waste bank management. The objects of this research are Dalang Collection Waste Bank and Inspirasi Madani Waste Bank, which were selected based on the criteria for determining the research location. Data processing is done quantitatively descriptively with SWOT analysis (weight and rating). Based on the calculation results, Dalang Collection Waste Bank receives an average of 298.6 kg/month of waste which 95.8% of waste can be processed while Inspirasi Madani Waste Bank receives an average of 9,740 kg/month of waste which 97.76% of waste can be processed. Based on the identification of internal and external factors of waste banks using SWOT analysis, Dalang Collection Waste Bank obtained IFAS and EFAS scores of (0.81; 0.72) and IFAS and EFAS scores of (0.91; 0.81) for Inspirasi Madani Waste Bank. The development strategy obtained from the SWOT matrix diagram by plotting the IFAS and EFAS values to the two waste banks is the strength-opportunity (SO) strategy, namely increasing the internal activities of waste banks and increasing cooperation with the government and stakeholders. Both waste banks have a positive impact on sustainable development and help in implementing a circular economy through waste utilization. Based on the total waste reduction analysis of their customers, Dalang Collection Waste Bank and Inspirasi Madani Waste Bank are able to process 0.5% and 10.5% of their customers' waste, respectively. Meanwhile, based on the analysis of waste reduction potential with the theoretical recovery factor, both waste banks can process up to 59.3% of their customers' total waste. Therefore, to maximize the utilization of waste through waste banks, it is necessary to optimize the two waste banks, namely from the technical (waste processing) and non-technical aspects (selling price and community participation). In addition, the residual waste generated by both waste banks can still be processed by several processes, namely composting, black soldier fly (BSF), incineration, and refuse derived fuel (RDF)
