| dc.description.abstract | Perubahan penggunaan lahan di Daerah Aliran Sungai Ciliwung Hulu
menimbulkan gangguan pada fungsi hidrologi Daerah Aliran Sungai. Penelitian ini bertujuan untuk menganalisis pola dan pengaruh perubahan penggunaan lahan
terhadap laju sedimentasi di Bendung Katulampa. Metode penelitian menggunakan
pemodelan hidrologi Soil and Water Assessment Tool. Data yang dianalisis meliputi
tutupan lahan dan data iklim tahun 2017 dan 2024, jenis tanah, dan kemiringan
lereng. Hasil penelitian menunjukkan bahwa di Daerah Aliran Sungai Ciliwung
Hulu terjadi peningkatan luas lahan terbangun sebesar 1040,7 ha dan penurunan
signifikan pada lahan perkebunan dan semak belukar dalam periode 2017 dan 2024.
Dampak dari perubahan penggunaan lahan tersebut mengakibatkan total laju
sedimentasi meningkat sebesar 18,6 juta ton/tahun. Input data global curah hujan
harian dan bulanan (Nasa Power) dan jenis tanah global (DSMW) memberikan nilai
Nash-Sutcliffe Efficiency (NSE) yang belum memuaskan yaitu sebesar -0,05
(harian) dan 0,32 (bulanan). | |
| dc.description.abstract | Land use changes in the Upper Ciliwung Watershed have disrupted the
watershed’s hydrological functions. This study aims to analyze the patterns and
impacts of land use changes on sedimentation rates at the Katulampa Weir. The
research method employed the Soil and Water Assessment Tool (SWAT)
hydrological modeling. The data analyzed included land cover and climate data
from 2017 and 2024, soil type, and slope gradient. The results show that in the
Upper Ciliwung Watershed there was an increase in built-up land area by 1040,7
ha and a significant decrease in plantation and shrubland areas during the 2017–
2024 period. The impact of these land use changes resulted in an increase in the
total sedimentation rate by 18,6 million tons/year. Global input data on daily and
monthly rainfall (NASA POWER) and global soil type (DSMW) produced
unsatisfactory Nash–Sutcliffe Efficiency (NSE) values of -0,05 (daily) and 0,32
(monthly). | |
