Pengaruh perubahan penggunaan tanah terhadap luas Danau Rawapening = The effect of landuse change towards Rawapening Lake s width / Tri Selasa Pagianti

Tri Selasa Pagianti; (Universitas Indonesia, 2014)

 Abstrak

[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 bersifat
dinamis. Perubahan penggunaan tanah di DTA Rawapening mempengaruhi besar
kecilnya erosi yang terjadi. Semakin besar erosi yang terjadi maka semakin
banyak pula sedimen yang terbawa ke Danau Rawapening. Banyaknya sedimen
yang terbawa ke danau berdampak pada perubahan luas danau yang nantinya juga
berimbas kepada fungsi danau itu sendiri. Hasil penelitian menyimpulkan bahwa
luas danau meluas ke arah barat yaitu di Subdas Torong. Subdas Torong memiliki
konsentrasi sedimen tersuspensi yang cukup tinggi yaitu 142 mg/l. Perubahan
penggunaan tanah di Subdas Torongcukup signifikan, fungsi lahan sebagai hutan
semakin berkurang dan akhirnya habis sedangkan permukiman semakin
bertambah. Dapat disimpulkan bahwa sedimen yang masuk ke dalam danau
mempengaruhi jumlah air yang dapat di tampung danau yang berimbas pada luas
danau itu sendiri.;Rawapening Lake is a part of Rawapening Water Catchment Area, which
has nine subwatersheds streaming into the lake. Landuse is considered as one
determinant factor of erosion. Landuse change in the Rawapening Water
Catchment Area determines the amount of erosion occurrence; the more the
erosion occurs, the more sediment is transported into the lake. The amount of
sediment in the lake may impact the lake’s width, and affects the function of the
lake. The research concludes that the lake’s width expands to the west side of the
lake, Torong subwatershed. Torong subwatershed has the second highest
suspended 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 is
increasing. In conclusion, the sediment which is transported into the lake affects
lake capacity and also its width., Rawapening Lake is a part of Rawapening Water Catchment Area, which
