Abstract

From 2017 to 2021, waste production in Ambon City increased from 200 tons/day to 297 tons/day, but the condition of the Toisapu landfill in Ambon did not support this. Toisapu landfill, which has been operating since 2007, is now in overload status and needs to be re-evaluated because it is on a slope of >20% and is located close to residential areas. This research aims to find an alternative replacement for the Toisapu landfill with the status of a Waste Processing and Final Processing Site that complies with Indonesian National Standards. This research uses an environmental geology approach based on Spatial Multi-Criteria Evaluation (SMCE), which combines geological and non-geological parameters. The analysis results for each parameter are overlaid, given a value, and then totaled to produce the most feasible land. The results of this research show that the most suitable land is in Wakal with an area of 126,668 ha. The permeability of this location is low, with the groundwater being quite deep (>80 meters), so there is little chance of leachate seepage contaminating the groundwater. In contrast to the Toisapu landfill, Wakal has a slope of <20%, far from protected forests and where residents live.

Abstract

The production of waste in Ambon City increased from 200 tons per day to 297 tons per day between 2017 and 2021, yet the state of the Toisapu landfill in Ambon did not keep up with this growth. The Toisapu landfill has been in operation since 2007, however, due to its proximity to residential areas and slope of more than 20 percent, it is currently in an overload state and requires a re-evaluation. The goal of this study is to identify a different landfill to replace the Toisapu landfill that fulfills the Indonesian National Standards and functions as a Waste Processing and Final Processing Site (TPPAS). This study combines an evaluation of the geological and non-geological parameters using an environmental geological technique called Spatial Multi-Criteria Evaluation (SMCE). In order to determine the most possible land, the study findings for each parameter are superimposed, assigned a value, and then added together. According to the research's findings, Wakal, which has 126,668 hectares of land is the best option. Since the groundwater in this area is quite deep (>80 meters) and has low permeability, there is minimal possibility of leachate seepage contaminating the groundwater. Wakal, unlike the Toisapu landfill, is located far from inhabited areas and protected forests, with a slope of less than 20%.
