Development of a solid waste service level index

Abstract

The performance of municipal solid waste management (MSWM) system can be determined by assessing its level of services. In Bandung City, the level of solid waste service was determined based on the amount of solid waste being transported to the final disposal site. According to the data from Cleaning state Company of Bandung City in 2017, the percentage of solid waste service level was 98.14%. However, it is visible that a large amount of solid waste at some of the temporary collection sites, riverbanks and runnels remains un-transported. This, and other evidences, indicated that the existing service level performance value was not representative for the overall solid waste service. Thus, this study aims to develop a solid waste service level index which can be used to assess performance of the MSWM Level of Service (LoS). This study was undertaken by selecting components, indicators and sub-indicators which are related to MSWM services, determining the weights for the components, indicators and sub-indicators, as well as defining the aggregation and interpretation of the final index. During the selection of components, indicators and sub-indicators, main literatures used were the Indonesian Government Regulation Number 81 of 2012, the Ministry of Environment Regulation Number 6 of 2014, Integrated Waste Management Scoreboard (IWMS) and Key Performance Index (KPIs) for MSWM. Through this study, 5 components, 26 indicators and 21 sub-indicators were identified and were rigorously analysed. The components were Technical Operation, Institution, Regulation, Finance and Public Participation. Weighting technique used for the index was the subjective weighting. Aggregation index using arithmetic method with the interpretation of the final index was made based on 5 categories and resulted is 76% LoS of Bandung City. In the near future, the developed index can be used to assess better the LoS of the MSWM of Bandung City.
