Multi-Attribute Utility Theory Decision Analysis for Biodegradable River Debris Composting Treatment in Surakarta City

Abstract

River waste in Surakarta City primarily consists of biodegradable waste that can be processed by biological processes such as composting. However, there are various kinds of composting application techniques. This, of course, must be adapted to the conditions in Surakarta City. This study aims to conduct a decision analysis on debris processing techniques in Surakarta City using the Multi-Attribute Utility Theory (MAUT) method. The criteria used are aesthetics, land requirements, ease of operation, ease of construction, and investment and operational costs. Alternatives used in composting are bamboo aerator system, hollow brick, and takakura arranges. The final assessment by MAUT showed that waste processing with hollow brick (0.802) had the highest weight and was followed by the bamboo aerator system (0.643). The final score for the takakura method is only 0.250, and this is because the weight on costs and land requirements is considerable compared to the other two alternatives.
