Abstract

Studi ini bertujuan untuk mengetahui potensi Sungai Rawa sebagai sumber energi bagi masyarakat lokal.Metode yang digunakan dalam studi ini adalah pengambilan data primer berupa data kedalaman sungai dari hulu(outlet) hingga 300 m ke arah terjunan, tinggi terjunan dan data sekunder yakni jumlah penduduk. Teknik pengolahandata meliputi pengukuran tinggi muka air, kecepatan dan luas penampang sungai juga menentukan letak/posisi intakesaluran pengambilan lengkap dengan dimensi saluran pengarah, bak penenang, bahan dan dimensi pipa serta tinggiterjunan yang akan dimanfaatkan sebagai pembangkit juga jarak lintasan dari bak penenang sampai ke rumah tenaga.Dari hasil analisis menunjukkan pembangkit yang dimungkinkan untuk memenuhi kebutuhan energi listrik masyarakatDesa Lindu adalah Pembangkit Listrik Tenaga Mikrohidro, dengan menggunakan 3 pipa pesat. Daya yang dapatdibangkitkan sebesar 503.04 kW sedangkan kebutuhan energi untuk Kecamatan Lindu sebesar 472.35 kW. Hasilpengukuran debit aktual sesaat sebesar 15 m3/dt.

Abstract

The Sulawesi River Basin Office 3 requires data on the characteristics of sediment grains to predict the frequency of sedimentation flushing. The Gumbasa Irrigation Area is located in the Palu valley area which extends from the headwaters of the Gumbasa River to the Kawatuna River in Palu City, namely: Gumbasa, Tanambulaya, Dolo, Sigi Biromaru and South Palu Districts. The Gumbasa Irrigation Area has an area of ​​1,737 Ha. This study aims to determine the amount of bedload sediment transport in the Sand Trap Channel of the Gumbasa Irrigation Area. In this research, bed load sampling, flow velocity and water depth in the channel were taken. Sampling was carried out in two seasons, namely at the beginning of the rainy season (February) and the end of the rainy season (March). The purpose of taking samples at two different times is to determine the difference in the amount of sediment transport at that time. The sediment samples are then tested in the laboratory to obtain grain diameter measurements with a passing percentage of 90% and 50% (D90 and D50). The data that has been obtained is then analyzed using the Meyer-Peter-Muller equation. The analysis results show that the amount of bedload sediment transport at the beginning of the rainy season using the Meyer-Peter-Muller equation is 184,966 m3/day, while at the end of the rainy season the amount of bedload sediment transport using the Meyer-Peter-Muller equation is 38,494 m3/day.
