“…Selain itu, pertumbuhan penduduk yang tidak terkendali, hilangnya hutan, peningkatan erosi tanah, ketimpangan dari pola distribusi hujan, dan sering terjadinya banjir merupakan beberapa penyebab terjadinya kerusakan dan penurunan kualitas DAS di Indonesia (Jefrizon, 2021;Karamma, 2018;Riswal dan Sukri, 2020;Pambudi, 2019). Dampak lanjutan dari kerusakan DAS ini adalah nilai ekonomi lahan berkurang, pendapatan dan ekonomi masyarakat menurun (Arfan et al, 2021;Herrawan et al, 2022;Hidayat et al, 2020) sehingga daya dukung DAS terhadap lingkungan menurun bahkan sampai pada level kritis.…”

“…Penurunan ketersediaan air tersebut sangat dipengaruhi oleh terganggunya kinerja ekosistem DAS karena penurunan fungsi lahan (Ilva et al, 2020). Penurunan fungsi lahan yang dimaksud dapat terjadi karena pola penggunaan/tutupan lahan berubah tidak sesuai yang diharapkan, terjadinya degradasi tanah dan kehilangan unsur hara, serta rendahnya cadangan air (storage) (Hidayat et al, 2020;Murtiyah et al, 2019;Rosmaladewi et al, 2019). Kondisi tersebut diatas juga banyak terjadi pada DAS-DAS di wilayah Provinsi Sulawesi Tenggara.…”

One of the priority watersheds in Southeast Sulawesi is the Poleang watershed. It is necessary to assess management performance to remain sustainable in its implementation. This research aims to determine the performance of poleang watershed management based on indicators of land conditions and determine recommendations for the direction of sustainable land management policies. The survey methods used in the research and analysis include land criticality, land cover and erosion in calculating carrying capacity. This research resulted in the fact that the land support in the Polean g watershed had a high class with a score of 1.25 based on the critical land sub-criteria. Sub-land cover criteria have an excellent category with a score of 0.5, and the erosion index sub-criterion has a very high category with a score of 1.5. Overall, the carrying capacity of the Poleang watershed is in the moderate category, so it is necessary to maintain land or increase the area of vegetation cover of the Poleang watershed through the application of vegetation conservation methods, technical conservation methods and mechanical conservation methods.
