Rapid population growth and the development of new settlements have led to significant and uncontrolled land use change, particularly the conversion of agricultural land to residential areas. This study explores the socioeconomic impacts of such changes in Pattalassang District, South Sulawesi, Indonesia, a newly established satellite city. Using qualitative descriptive analysis, spatial analysis, and quantitative analysis, as well as SWOT analysis, we found that the conversion of agricultural land into settlements has led to an increase in population, changes in social activities, a decline in traditional harvesting culture, and a decrease in crime rates. Economically, these changes have opened up new employment sectors, created side jobs, reduced unemployment, and increased incomes and land prices. However, our analysis also revealed that 5.46% of residential land in 2011 and 30% in 2021 did not improve. Comply with spatial plans. Our findings underscore the need for coordination of spatial planning policies at the provincial, district, and metropolitan levels and emphasize the importance of consistent and transparent policy implementation, particularly in relation to protected paddy fields.
