Abstrak

Penanggulangan erosi di kawasan Danau Batur berbasis masyarakat diarahkan untuk mempertahankan keseimbangan Danau Batur. Erosi dipicu oleh pola pengelolaan lahan-lahan pertanian kurang memperhatikan aspek-aspek konservasi tanah dan air. Tujuan penelitian ini adalah ; (1) untuk memperoleh model penanggulangan erosi yang berbasis masyarakat, (2) Pemetaan Pengelolaan lahan di pinggir danau, (3) Stategi pengendalian erosi di tepian danau. Penelitian ini field experiment dan surpei, pengambilan sampel dilakukan secara purposive sampling dengan jumlah 64 sampel. Data dukungan sosial ekonomi masyarakat ditentukan sebanyak 180 responden secara cluster sampling. Wawancara dan kuesioner berupa pertanyaan tertutup dalam skala konvensional. Karakteristik danau dianalisis statistik deskriptif menggunakan alat SPSS. Pemetaan lahan dilakukan dengan metode GPS dengan perangkat GIS. Memprediksi erosi menggunakan Model The Universal Soil Loss Equation (USLE), untuk sedimentasi menggunakan model Sediment Stanford. Analisis laju akibat erosi, dilakukan dengan cara analisis regreresi non linear. Hasil analisis menunjukan pemukiman bertambah rata-rata 115,85 %, perkebunan 245,50 % dan tingkat sedimentasi 1.017,93 m3/tahun. Sedimentasi diuji dua sisi dengan tingkat kepercayaan 95% terhadap data sedimen yang dimodelkan. Simpulan untuk menanggulangi erosi mempergunakan model penataan lahan Terasering Mekar berbasis masyarakat yang berklaborasi dengan tumbuhan rumput gajah dan vetiveria.
