Abstract

This study investigated the potential of anaerobic digestion sludge derived from palm oil mill effluent (POME) to enhance the structure of sandy soils in the Samas Coastal Area, Bantul Regency, Yogyakarta. Sandy soils, having low water retention and nutrient-holding capacity, present significant challenges for sustainable agriculture. By applying different volumes of digestate (0 ml, 50 ml, 100 ml, 200 ml, 400 ml, and 800 ml per kilogram of soil) in a 30-day greenhouse experiment, this research assessed the impact of POME sludge on soil structure improvements, particularly focusing on aggregation, porosity, and bulk density. Treatments with higher digestate volumes, especially 800 ml/kg, yielded substantial improvements in soil aggregation, contributing to better moisture retention. Enhanced aggregation facilitated improved water retention and root penetration, indicating that anaerobic digestion sludge could effectively amend sandy soil limitations. These findings underscore the potential of POME-derived organic amendments as sustainable soil conditioners, offering a dual benefit of waste valorization and enhanced agricultural productivity for marginal soils in coastal areas.

Abstract

Cutting slopes and backfilling land to make land plots for housing is a common practice in Indonesia.This study aims to identify the impact of cutting slopes and backfilling for the construction of residential plots in Imogiri Subdistrict, Bantul Regency, Yogyakarta Special Province. The study employed a field survey at the study site determined by purposive sampling method to find and evaluate the existing condition. Data was also obtained from literature studies and interviews with local communities. Data analysis was carried out in a spatial qualitative descriptive manner, using a geographic information system approach, with the help of ArcGIS 10.8 Software. The results showed that cutting slopes and backfilling have negatively impacted the environment and local communities. In the backfill process, it is necessary to strengthen the supporting slopes of the piled-up soil, control the water content and compact the soil properly to maintain slope stability and prevent a decrease in soil volume. In addition, it is necessary to periodically monitor the condition of the slopes and the surrounding environment to avoid the possibility of other negative impacts.
