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.

泗水市可生物降解河滩堆肥处理的多属性效用理论决策分析

泗水市的河流废物主要由可生物降解的废物组成，可以通过堆肥等生物过程进行处理。然而，有各种各样的堆肥应用技术。当然，这必须适应泗水市的条件。本研究旨在运用多属性效用理论(Multi-Attribute Utility Theory, MAUT)方法，对雅加达市垃圾处理技术进行决策分析。使用的标准是美观性、土地要求、易于操作、易于建造以及投资和运营成本。在堆肥中使用的替代品是竹制曝气系统，空心砖和高仓安排。MAUT最终评价结果表明，空心砖处理的垃圾重量最高(0.802)，竹材曝气系统次之(0.643)。takakura方法的最终得分仅为0.250，这是因为与其他两种替代方法相比，成本和土地需求的权重相当大。
