Abstract

Initial survey results on Towua Road (Sta. Km 0+000–Km 1+000) indicate that the flexible pavement has experienced various forms of damage, including surface layer stripping, aggregate loss, split damage, and cracking. These conditions not only reduce driving comfort but also have the potential to compromise road user safety if not handled properly. This study aims to evaluate the types and levels of flexible pavement damage, determine the priority value for damage handling based on the Bina Marga method, and identify the factors causing the damage as a basis for formulating maintenance recommendations for Towua Road. The research method was conducted through a visual field survey on observation segments according to stationing (Sta.), after which the damage data were analyzed using the Bina Marga assessment procedure to obtain the percentage of pavement damage and the Priority Order (PO) for maintenance handling. Based on the analysis results, the total percentage of pavement damage was recorded at 45.84 percent, equivalent to 4,125.88 m² of the total observed road area. The obtained priority value was PO = 3, indicating that the road condition is classified as severely damaged and therefore requires pavement improvement treatment. Accordingly, the recommended action for Towua Road is overlay resurfacing (additional pavement layer) to restore road service performance and improve user comfort and safety.

Abstract

Sedimentasi di wilayah hulu sungai dapat menurunkan efektivitas fungsi bendung. Penelitian ini bertujuan untuk memodelkan angkutan sedimen dasar di hulu Bendung Sekka-Sekka, Kabupaten Polewali Mandar, menggunakan perangkat lunak HEC-RAS versi 6.6.1. Pendekatan yang digunakan adalah kuantitatif melalui simulasi numerik. Data diperoleh melalui survei lapangan, pengambilan sampel sedimen dasar, serta uji laboratorium berupa analisis saringan dan pengujian berat jenis. Data tersebut digunakan sebagai input pemodelan untuk mensimulasikan proses transportasi sedimen. Hasil simulasi menunjukkan bahwa titik RS 115.00 mengalami lonjakan kecepatan aliran dan tegangan geser pada awal Agustus 2024, yang menyebabkan peningkatan akumulasi sedimen secara signifikan. Temuan ini menunjukkan bahwa wilayah hulu memberi kontribusi besar terhadap sedimentasi di bendung. Pemodelan ini memberikan gambaran kondisi nyata transportasi sedimen dan menjadi dasar dalam merancang strategi pengendalian. Rekomendasi strategi pengelolaan meliputi pengerukan berkala dan pembangunan bangunan pengendali sedimen di hulu. Hasil penelitian ini diharapkan dapat menjadi acuan dalam pengelolaan daerah aliran sungai secara berkelanjutan untuk menjaga fungsi bendung dan mendukung sistem irigasi yang efisien di wilayah sekitarnya
