Abstract

Land use change from agricultural land into non-agricultural land such as for industries, streets, and others has increased erosion impact, nutrient and sediment in a watershed. That process had caused land degradation in a watershed, therefore, land productivity will decrease and even will cause flood during rainy season and drought during dry season. In order to find out what will happen if land use change takes part, a software using BASIC language was arranged. This software is aimed to simulate erosion process easier. This software uses USLE and Snyder in predicting erosion. Additionally, this software is also able to predict sediment delivery.Keywords : Software conservation, language BASIC.

Abstract

Kondisi Sungai Batanghari saat ini telah banyak mengalami deformasi morfologi sungai akibat banyaknya praktek galian C dan penambangan ilagal di sepanjang tubuh sungai. Deformasi morfologi Sungai Batanghari diprediksi dapat menyebabkan kerusakan pada tubuh sungai Batanghari dan mengakibatkan penurunan potensi sumber daya air. Penelitian ini bertujuan untk mengetahui perubahan morfologi Sungai Batanghari akibat kegiatan penambangan emas ilegal disepanjang sungai dan anak-anak sungainya. Pendekatan penelitian ini menggunakan model “stratified purpose sampling“ melalui teknik penginderaan jauh dengan wahana citra satelit Landsat-7 ETM.Berdasarkan hasil analisis, Sungai Batanghari mengalami perubahan fisik baik menyangkut badan sungai, lingkungan sungai maupun kualitas air. Perubahan badan sungai terkait kegiatan penambangan tanpa Ijin (PETI) terjadi di beberapa lokasi baik pada sungai utama maupun pada anak-anak sungai Batanghari seperti di Dharmasyraya, Bungo, Batanghari dan Solok Selatan. Kata Kunci: Penambangan ilegal, Kerusakan Morfologi, Citra landsat-7 ETM, Sungai Batanghari
