Abstract

This study analyzes the implementation of a widening project on a road section in the Branjang-Lerep area, Semarang Regency, Central Java, with a focus on the flexible pavement sub-layer. This project was carried out by a contractor under the supervision of the project implementer. The scope of work included earthworks, channels and culverts, granular pavement, and flexible pavement. The research method used field observations, literature studies, and interviews. The observations revealed significant challenges related to extreme geographical conditions (slopes, sharp bends), weather, and social aspects (heavy traffic). Although material quality control demonstrated adequate results, the implementation of Occupational Health and Safety (OHS) still needed improvement. Implemented solutions included adapting the asphalting work schedule, using heavy equipment adapted to the terrain, and partial traffic management to maintain the smooth flow of community activities. This article provides a comprehensive overview of the challenges and adaptation strategies in road infrastructure projects in areas with difficult topography and heavy traffic.

Abstract

Penelitian ini memfokuskan pada desain teknis dinding penahan tanah sebagai solusi penanganan longsor di Ruas Jalan Patikraja – Rawalo KM. 16+900, Kabupaten Banyumas. Ruas jalan ini, yang merupakan bagian dari Jalur Lintas Selatan Pulau Jawa dengan fungsi Jalan Arteri Primer, berdekatan dengan Sungai Serayu yang berpotensi menyebabkan gerusan. Metodologi meliputi pengumpulan data, analisis hidrologi, hidrolika, sedimentasi, gerusan, serta perancangan awal struktur pelindung. Data penyelidikan tanah, beban lalu lintas, dan karakteristik material digunakan untuk menentukan dimensi, stabilitas, dan perancangan tulangan dinding penahan tanah (DPT) tipe beton bertulang dengan fondasi bored pile. Hasil analisis menunjukkan perlunya fondasi bored pile diameter 60 cm dengan panjang 10 m, disertai tulangan pokok D19-100 pada bagian bawah dinding dan D16-100 pada bagian atas, serta tulangan lentur D22-100 untuk pile cap. Kontrol stabilitas guling, geser, dan daya dukung menjadi krusial dalam memastikan keamanan struktur.

Abstract

This study analyzes the hydrological and hydraulic characteristics of the Patikraja-Rawalo road section in Banyumas Regency, which is adjacent to the Serayu River and is prone to landslides. The main focus is on watershed delineation (DAS), design rainfall determination, flood discharge calculation, floodwater elevation determination, and scour depth. Using historical rainfall data and hydrological modeling (Nakayasu and HEC-HMS) and hydraulic modeling (HEC-RAS 2D), the 50-year design flood discharge is 2,217.80 m³/s and a maximum scour depth of 2.51 m. These results provide a crucial basis for designing retaining walls to ensure road stability.
