ANALISIS PRODUKTIVITAS EXCAVATOR DAN DUMP TRUCK BERDASARKAN PENDEKATAN PERMEN PUPR NO 28 TAHUN 2016 PADA PROYEK JALAN TOL (Studi Kasus Pembangunan Jalan Tol Jakarta - Cikampek Seksi II B)

This study aims to analyze the productivity of excavators and dump trucks in earthmoving work in Section II B Ram 4 (STA. 0+00 – STA. 1+025) with an earthmoving work volume of 1,215 m³. The results of the analysis show that the productivity of one excavator unit is 643.76 m³/day, while two units reach 1,287.53 m³/day so that the work volume of 1,215 m³ can be completed in one day. Meanwhile, a dump truck with a productivity of 78.38 m³/day is able to reach 1,254.19 m³/day using 16 units and can complete the work in one working day. Heavy equipment productivity is influenced by several factors, namely the age of the equipment, operator skills, soil material, and weather conditions. Older equipment age reduces efficiency, where the old category excavator only produces 1,158.77 m³/day. Operator factors have a direct impact, with the highest productivity achieved by expert operators, while intermediate and amateur operators experience significant declines. Red soil, with a coefficient of 0.80, also reduces excavator and dump truck productivity. Furthermore, weather factors, particularly rain with a coefficient of 0.4, can reduce productivity by more than 50%. Therefore, optimizing excavators and dump trucks is crucial. Excavators require bucket cleaning and lubrication/oiling during breaks to prevent material from sticking during excavation. For dump trucks, the equipment requires cleaning the bed to prevent soil from sticking during dumping. Furthermore, clear weather conditions are crucial to ensure the productivity of both machines is not hampered.
