This study aims to determine the quality of the substrate soil on the Tamarupa Coast in Pangkep Regency. This study is a survey, involving sampling of substrate soil based on its characteristics and research objectives, followed by laboratory analysis. The collected data included ammonia, nitrate, pH, nitrogen, phosphate, and soil texture. The data were then analyzed using descriptive analysis. The results of the study showed that the ammonia content of the substrate soil at the research location was still relatively high because it was greater than 1 ppm, the nitrate content of the substrate soil at the research location was relatively low. The pH value of the substrate soil was in the normal range, namely 7.31 to 7.66. The nitrogen content of the substrate soil at the research location was still relatively low. The highest phosphate content was at ST 3, which is a location close to residential areas and fish farms, namely 0.006 ppm. The phosphate value for all research locations was still relatively low. Furthermore, the texture of the substrate soil at the research location had a dusty texture.
