Study of Capacity and Technical Design for the Arrangement of Sungai Dua Landfill in Tanah Bumbu Regency South Kalimantan Indonesia

Waste management is a significant challenge faced by cities worldwide. With the increasing population and economic activities, the volume of generated waste also rises significantly. To address this issue, landfills have become crucial facilities in waste management systems. This research aims to analyze the existing condition and capacity of Sungai Dua Landfill in facing the increasing waste volume. The research methodology includes field observation and data analysis through calculations of waste generation and composition, population projection, and land requirements at Sungai Dua Landfill. The research found that the waste generation entering Sungai Dua Landfill is 0.50 kg/person/day with a waste volume of 2.33 liters/person/day. The total area of Sungai Dua Landfill is approximately 2.163 hectares, with ± 0.8 hectares (or 8,000 m²) designated as the active area for accommodating waste generated by residents within the service area and transported to the landfill. The solid waste management system at Sungai Dua Landfill uses the controlled landfill method. If a waste reduction of 70% is implemented, the remaining land and service life of Sungai Dua Landfill can still accommodate the incoming waste until 2035. With a 70% reduction, only residual waste enters the landfill, thus the required land in 2035 is estimated to be 0.7 hectares. Keywords: capacity, existing conditions, Sungai Dua Landfill
