[Danau Rawapening merupakan bagian dari Daerah Tangkapan Air (DTA)Rawapening yang memiliki sembilan subdas yang mengalir menuju danau ini.Penggunaan tanah merupakan salah satu faktor penentu erosi yang bersifatdinamis. Perubahan penggunaan tanah di DTA Rawapening mempengaruhi besarkecilnya erosi yang terjadi. Semakin besar erosi yang terjadi maka semakinbanyak pula sedimen yang terbawa ke Danau Rawapening. Banyaknya sedimenyang terbawa ke danau berdampak pada perubahan luas danau yang nantinya jugaberimbas kepada fungsi danau itu sendiri. Hasil penelitian menyimpulkan bahwaluas danau meluas ke arah barat yaitu di Subdas Torong. Subdas Torong memilikikonsentrasi sedimen tersuspensi yang cukup tinggi yaitu 142 mg/l. Perubahanpenggunaan tanah di Subdas Torongcukup signifikan, fungsi lahan sebagai hutansemakin berkurang dan akhirnya habis sedangkan permukiman semakinbertambah. Dapat disimpulkan bahwa sedimen yang masuk ke dalam danaumempengaruhi jumlah air yang dapat di tampung danau yang berimbas pada luasdanau itu sendiri.;Rawapening Lake is a part of Rawapening Water Catchment Area, whichhas nine subwatersheds streaming into the lake. Landuse is considered as onedeterminant factor of erosion. Landuse change in the Rawapening WaterCatchment Area determines the amount of erosion occurrence; the more theerosion occurs, the more sediment is transported into the lake. The amount ofsediment in the lake may impact the lake’s width, and affects the function of thelake. The research concludes that the lake’s width expands to the west side of thelake, Torong subwatershed. Torong subwatershed has the second highestsuspended sediment concentration among the nine subwatersheds, 142 mg/l.Landuse change in Torong subwatershed is quite significant from time to time,forest was decreasing and eventually vanished, on the other hand, building isincreasing. In conclusion, the sediment which is transported into the lake affectslake capacity and also its width., Rawapening Lake is a part of Rawapening Water Catchment Area, whichhas nine subwatersheds streaming into the lake.
