Environmental carrying capacity based on ecosystem services of Penajam Paser Utara Regency

Until 2017, the economy of Penajam Paser Utara Regency was still dominated by the primary sector of agriculture, plantations, and mining. The exploitation of this sector is oriented ateconomic growth resulting in environmental degradation and a decrease in ecosystem quality as indicated by the intensity of natural disasters. Notably, over the past eight years, there have been forty-six natural disasters. Therefore, the land use planning in Penajam Paser Utara Regency must be evaluated based on the carrying capacity of the environment. One possible approach is an ecosystem services assessment to ensurethat future land use planning can match its ecosystem carrying capacity. The purpose of this research is a three-stageevaluation of land use planning in Penajam Paser Utara Regency based on the characteristics of itsecosystem services. First, environmental support analysis based on ecosystem services uses the Analytical Hierarchy Process assessment to obtain the weight of each variety. Then, thecalculatedcurrent carrying capacity index is transformed into maps with five classifications namely very low, low, medium, high and very high. The study found twenty-two types of ecosystem services in Penajam Paser Utara Regency and the most dominant is the ecosystem service for energy provision with an area of 119.979 Ha.
