Abstract

Telah dilakukan penelitian tentang Evaluasi Perubahan Perilaku Erosi Daerah Aliran Sungai Rammang-Rammang dengan Pemodelan Spasial. Tujuan penelitian adalah untuk mengevaluasi perubahan perilaku erosi daerah aliran sungai Rammang-Rammang dari tahun 2003 sampai tahun 2012 dengan pemodelan spasial. Metode yang digunakan  adalah USLE (Universal Soil Loss Equation) dengan pendekatan Sistem Informasi Geografis. Proses dimulai dengan pengumpulan data sekunder berupa data curah hujan yang diperoleh dari Badan Meteorologi, Klimatologi dan Geofisika (BMKG) Kabupaten Maros. Data peta, yakni peta jenis tanah, peta kemiringan lereng dan peta penggunaan lahan yang diperoleh melalui software ArcGIS. Hasil penelitian ini menunjukkan bahwa dari seluruh area Daerah Aliran Sungai Rammang-Rammang, nilai laju erosi sangat berat terjadi pada area dengan luas wilayah 106,4663 Ha, dengan satuan lahan Rawa Lahan Terbuka (R-L/T) dengan nilai laju erosi 112,4021 ton/ha/tahun atau sebesar 280,89296 ton/tahun dan berada pada tingkat kelerengan >40% (sangat curam). Sedangkan laju erosi ringan terjadi pada area terbesar dengan luas wilayah 1.920,198 Ha. Dan nilai laju erosi ringan terjadi pada satuan lahan Hutan (H) dengan nilai laju erosi 0,003295 ton/ha/tahun atau sebesar 0,10450 ton/tahun. Kata kunci : Erosi, USLE dan Sisten Informasi Geografis (SIG)

Abstract

This research aims to explore the role of local governments in providing education to the community to prevent human trafficking through offers to work abroad, with a focus on the situation in Tanjung Morawa. The research method used is a qualitative approach with case studies as the focus, which makes it possible to gain an in-depth understanding of the role of local government and the level of community understanding regarding the risk of human trafficking. Through interviews, data was collected to find out the prevention efforts carried out by the local government. The research results show that although public understanding of the risks of human trafficking is still low, preventive measures taken by village governments, such as educational programs through various platforms, can be an effective means of increasing awareness and reducing the potential for human trafficking to occur. This research highlights the important role of local governments in efforts to prevent human trafficking and emphasizes the need to continue monitoring and increasing outreach and education efforts to the community.

Abstract

This study aimed to determine the effect of biofertilizer containing endophytic bacteria from the roots of Indian almond trees (Terminalia catappa) on the growth and yield of lowland rice (Oryza sativa). The experiment used a completely randomized design (CRD) with three treatments: NPK fertilizer, endophytic bacterial biofertilizer, and a combination of both, each with three replications. Observed parameters included root dry weight, dry grain weight, and dry rice weight. The results showed that the endophytic bacterial treatment significantly increased all measured parameters compared to NPK and the combination treatments. Treatment A2 (endophytic bacteria) produced the highest values across all variables. These findings indicate that endophytic bacteria from the roots of Terminalia catappa have great potential as a biofertilizer to support sustainable and environmentally friendly rice cultivation.
