Abstract

Kondisi jalan merupakan komponen vital dalam sistem transportasi darat yang menjadi tulang punggung pembangunan ekonomi dan sosial. Tujuan penelitiaan ini yaitu, Mengetahui jenis kerusakan ruas Jalan Pahlawan Kecamatan Enrekang Kabupaten Enrekang dengan metode SDI dan Mengetahui cara menentukan jenis penanganan kerusakan jalan berdasarkan hasil analisis metode SDI ruas Jalan Pahlawan Kecamatan Enrekang Kabupaten Enrekang. Penelitian ini dilakukan di Jalan Pahlawan yang memiliki panjang sekitar 0,640Km, dari titik awal yaitu di Bambu Runcing (STA 0+00) berakhir di Simpang Empat Jl. Pangeran Hidayat, Jl. Mata Dewa dan Jl. Penja (STA 0+640) menggunakan metode Surface Distress Index (SDI) dengan interval pengamatan setiap 50 meter. Berdasarkan hasil perhitungan Lalu Lintas Harian Rata-rata (LHR), diperoleh volume lalu lintas sebesar 750,9 smp/hari. Nilai rata-rata SDI pada ruas Jalan Pahlawan dari STA 0+000 sampai STA 0+640 adalah sebesar 51,54%, yang menunjukkan bahwa kondisi jalan berada dalam kategori sedang. Oleh karena itu, jenis penanganan yang direkomendasikan adalah pemeliharaan berkala.

Abstract

The availability of irrigation water is an essential factor in increasing agricultural productivity and supporting sustainable farming activities. Garutu Hamlet, Buttu Batu Village, Enrekang District, Enrekang Regency has an agricultural area of 22.08 hectares; however, the distribution of irrigation water has not been optimal. Therefore, the planning of a primary irrigation canal is required to ensure an effective and equitable water supply.The data consisted of primary data obtained from field surveys and existing canal measurements, as well as secondary data including rainfall records from 2015–2024, climatological data, topographic maps, and agricultural land area. The analyses included the determination of design rainfall (R80), dependable discharge (Q80), Net Field Requirement (NFR), and the design of the primary irrigation canal using the Manning equation.The results indicate that the design rainfall (R80) is 312.48 mm, the average dependable discharge (Q80) is 0.469 m³/s, and the maximum irrigation water requirement is 0.138 m³/s with an irrigation efficiency of 61.2%. Based on the hydraulic analysis, the proposed trapezoidal primary irrigation canal has a bottom width of 0.80 m, a flow depth of 0.55 m, a freeboard height of 0.60 m, a total canal depth of 1.15 m, a side slope of 1:1, and a longitudinal bed slope of 0.021. The designed canal has a discharge capacity of 0.543 m³/s with a flow velocity of 0.73 m/s, indicating that it is capable of safely conveying the required irrigation discharge throughout the year. Therefore, the proposed canal dimensions satisfy the technical design requirements and are expected to improve water distribution efficiency and support increased agricultural productivity in Garutu Hamlet.
