The Penujah landfill, serving as Tegal Regency’s primary waste disposal site, has exceeded its 4.1-hectare capacity and operational lifespan since 2018, leading to environmental and social problems such as odor nuisance, leachate leakage, and land-use conflicts. Therefore, this study aims to identify suitable alternative sites for a new landfill facility to replace the Penujah landfill, using a Geographic Information System (GIS) and criteria from the Indonesian National Standard (SNI) 19-3241-1994. The GIS analysis applies three stages—Regional, Exclusion, and Determination—while incorporating additional local factors such as flood vulnerability, cultural heritage buffers, and population density. Results identify three potential locations—Kedungbanteng, Pangkah, and Margasari—with Kedungbanteng emerging as the most suitable due to its large available area, good road access, and low settlement density. This study highlights the importance of systematic site selection in municipal solid waste management and demonstrates how GIS can support evidence-based decision-making for sustainable landfill development in developing countries, especially Indonesia.
