Application of the Spatial Multi Criteria Evaluation (SMCE) Method for Planning the Location of Waste Final Processing Sites (TPA) in Kotabaru District

Abstract

Kotabaru Regency consists of 22 sub-districts with an area of 9,442.46 km2 and a population of 325,622 people in
2020. Kotabaru Regency has one TPA with an open dumping processing system, but these efforts are also not
optimal due to the condition of open dumping waste storage holes. it is almost full and the population is increasing
every year so that land suitability information is needed to develop a landfill site in Kotabaru District. Because of
this, this plan was carried out to analyze suitable locations for landfill planning in Kotabaru district in eight subdistricts. This planning uses Geographic Information System (GIS) technology in the GIS there is a Spatial Multi
Criteria Evaluation (SMCE) method. This planning refers to SNI 19-3241-1994 as a standard in determining the
location of TPA. Analysis of the feasibility of the TPA location begins with an analysis of regional criteria with the
principle of the regional binary method that matches the parameter with a value of 1 while those that are not
suitable are given a value of 0, the result is 1,170.356 km2 and the results of the exclusion criteria are divided into
4 classes where class IV is stated as land suitability is very suitable with an area of 9,574 km2 which is spread over
eight sub-districts in Kotabaru Regency. After the analysis was carried out, the location with the highest score was
obtained in the pulau laut selatan in the village of Tanjung Seloka. However, this location is very far from the
service area which will make it difficult to transport waste to the final waste processing location, so two alternative
locations are recommended for the final waste processing site which are close to the service area, Sebelimbingan
Village on the pulau laut utara and Selaru Village on the pulau laut tengah
