Abstract

Hidrologi merupakan salah satu faktor yang diperlukan untuk penyelesaian suatu permasalahan sumber daya air. Analisa curah hujan sangatlah diperlukan sebelum melakukan suatu prediksi. DAS Rongkong seluas 1728,034 Km²yang terletak di Kabupaten Luwu Utara mengalami permasalahan tentang peralihan tata guna lahan yang menyebabkan kemampuan infiltrasinya menjadi berkurang. Tujuan dari penelitian ini adalah untuk prediksi curah hujan di DAS Rongkong dan mengetahui perbandingan antara data lapangan dengan data hasil prediksi menggunakan Metode Jaringan Syaraf Tiruan (JST) Back Propagation. Berdasarkan hasil penelitian diperoleh hasil pada tahun 2022 bulan Januari: 66 mm, Februari : 25 mm, Maret : 22 mm, April : 19 mm, Mei : 22 mm, Juni : 40 mm, Juli : 18 mm, Agustus : 18 mm, September : 66 mm, Oktober : 18 mm, November : 30 mm, Desember : 67 mm. Berdasarkan Grafik data lapangan dengan data hasil prediksi Metode JST Pada bulan Januari, September dan Desember curah hujan wilayah yang dihasilkam mengalami kenaikan ,Sedangkan Pada bulan Februari, Maret, April, Mei, Juni, Juli, Agustus dan November curah hujan wilayah yang dihasuilkan mengalami penurunan. Sehingga Rata-rata selisih yang dihasilkan sebesar 13,83 mm.

Abstract

The Noling River plays an important role in the lives of the surrounding communities; however, it faces sedimentation problems that lead to riverbed aggradation, infrastructure disturbances, and reduced flow capacity. This study aims to determine the sediment characteristics and the rate of sedimentation in the Noling River, Luwu Regency. Sediment samples were collected from the midstream section of the river and analyzed in the laboratory to determine grain size distribution, specific gravity, and physical characteristics of the sediment. The results show that the Noling River sediment is dominated by sand (57.4%), gravel (31.8%), and silt/clay (10.9%), with a sediment classification of sandy clay. The sedimentation rate was calculated using both direct measurement and empirical approaches (Meyer-Peter and Duboys methods). The average suspended sediment load was found to be 5,251.97 tons/month, while the bed load reached 1,102.91 tons/month. The flow velocity, which exceeds the sediment fall velocity, indicates that sediment transport occurs actively. The findings of this study are expected to serve as a reference for better river management and future sedimentation mitigation efforts.
