Identifikasi Kerusakan Jalan dengan Metode Surface Distress Index (SDI) pada Ruas Jalan Menuju Kawasan Wisata Rinjani Via Torean

Abstract

Abstract: The Loloan–Torean Road is a major access route to the Mount Rinjani tourism area and plays an important role in supporting tourism activities, economic development, and community mobility in Bayan District, North Lombok Regency. Increasing traffic activity, hilly topographic conditions, and high rainfall have contributed to the deterioration of pavement conditions, necessitating periodic road condition evaluations to ensure road performance and user safety. This study aims to identify pavement distress types and assess road conditions using the Surface Distress Index (SDI) method. Data were obtained through a visual survey of a 6,500 m-long road section with a width of 3.5 m, which was divided into 100 m observation segments. The analysis was conducted based on the guidelines issued by the Directorate General of Highways and Bridges (DJBM) to determine SDI values, road condition categories, and appropriate maintenance recommendations. The findings indicate that the identified pavement distresses included cracks, potholes, patches, rutting, and raveling. The SDI values ranged from 40, categorized as good, to 67.5, categorized as moderately damaged, and 172.5, categorized as severely damaged, while the average SDI value was 28.923, indicating that the overall condition of the road section was categorized as good. These findings can serve as a basis for establishing road maintenance priorities and supporting decision-making to improve road performance, user safety, and the sustainability of access to the Mount Rinjani tourism area.

Abstrak: Ruas Jalan Loloan–Torean ialah akses utama menuju kawasan wisata Gunung Rinjani yang berperan penting dalam mendukung aktivitas pariwisata, perekonomian, dan mobilitas masyarakat di Kecamatan Bayan, Kabupaten Lombok Utara. Peningkatan aktifitas lalu lintas, keadaan topografi perbukitan, serta tingginya curah hujan sebabkan penurunan keadaan perkerasan sehingga diperlukan evaluasi keadaan jalan secara berkala untuk menjamin kinerja jalan dan keselamatan pengguna. Studi ini bertujuan mengidentifikasi jenis kerusakan perkerasan serta menilai kondisi jalan dengan metode surface distress index (SDI). Data didapat pada survei visual ruas jalan 6.500 m beserta lebar 3,5 m yang dibagi menjadi segmen pengamatan tiap 100 m. Analisis dilaksanakan berlandaskan pedoman DJBM untuk menetapkan nilai SDI, kategori keadaan jalan, dan rekomendasi penanganan. Temuan studi memperlihatkan kerusakan yang ditemukan seperti retak, lubang, tambalan, alur, dan pelepasan butir. Nilai SDI berkisar 40 (baik), 67,5 (rusak sedang), hingga 172,5 (rusak berat), sedangkan nilai SDI rerata senilai 28,923 yang memperlihatkan keadaan ruas jalan secara umum tergolong baik.Temuan studi ini bisa menjadi dasar dalam menetapkan prioritas pemeliharaan jalan serta mendukung pengambilan keputusan untuk meningkatkan kinerja jalan, keselamatan pengguna, dan keberlanjutan akses menuju kawasan wisata Gunung Rinjani.
