Muhammad Natsir — 2023-03-31

This research aims to determine the factors that cause erosion, measure the level and how to overcome the dangers of erosion in the Bolapapu watershed. This research was conducted in the Bolapapu watershed which is located in the middle of the Miu sub-watershed and is located in Kulawi District, Sigi Regency, Central Sulawesi Province. The results of the research show that in various forms of land use using plant management methods (C) and conservation techniques, namely soil management (P), there are several things that can be concluded: (1) changes in plant management factors on each land unit can prevent the level of danger of erosion and can increase land productivity; (2) conservation measures, namely soil management (P), can change the physical shape of the length and slope of the slope and inhibit the rate of runoff; (3) in land rehabilitation efforts using plant and soil management methods in relation to erosivity which can change the physical form of erodibility; (4) land rehabilitation planning in the Bolapapu watershed can not only reduce the level of erosion hazard or increase land productivity, but can improve the economic conditions of the community through plant management. economically valuable actions through conservation techniques.

Yusuf Sulo — 2023-03-31

Kerusakan habitat dan perburuan anoa menyebabkan penurunan populasi yang akan berdampak pada penurunan populasi anoa yang berujung pada kepunahan satwa ini. Penelitian ini bertujuan untuk mengetahui tingkat okupansi habitat anoa dan faktor-faktor lingkungan yang mempengaruhinya di Cagar Alam Gunung Dako Kabupaten Tolitoli. Penelitian ini menggunakan metode survei pemodelan okupansi spesies yang kemudian dianalisis untuk mengetahui okupansi anoa dan faktor-faktor yang mempengaruhinya dengan menggunakan aplikasi PRESENCE (MacKenzie et al. 2002; MacKenzie et al. 2006). Teknik pembuatan unit sampel/grid dilakukan dengan membagi peta peruntukan Cagar Alam Gunung Dako menjadi 62 grid dengan ukuran 2.000 m x 2.000 m (400 ha). Hasil penelitian menunjukkan bahwa anoa menempati sekitar 67,59% hingga 85% habitat di Cagar Alam Gunung Dako, Kabupaten Tolitoli. Tiga model kovariat lingkungan yang terbaik dan berkorelasi positif menunjukkan bahwa anoa lebih menyukai daerah yang jauh dari kawasan budidaya dan juga jauh dari jalan dan tutupan hutan primer yang luas.
