Analisa Produktivitas Penggunaan Alat Berat Gali�Muat (Excavator) dan Alat Angkut (Dump truck) Terhadap Efisiensi Biaya Dan Waktu Pada Pekerjaan Spillway STA 1+25 S/D 6+50 Proyek Bendungan Bagong Tahap II Kabupaten Trenggalek

Dam construction is an infrastructure project that has a central role in meeting
water, energy and flood control needs in an area. In this context, heavy equipment
such as Excavators and Dump Trucks are the backbone in supporting the smooth
running of construction projects. The Bagong Dam Phas e II project in Trenggalek
Regency is an important example in this regard, because it shows the complexity
faced by digging-loading heavy equipment such as Excavators and transportation
equipment such as Dump Trucks in optimizing time and costs. The objectives of this
research are: 1) Find the right combination for the number and cost of Excavator
and Dump heavy equipment on the Bagong Dam Project Phase II in Trenggalek
Regency, 2) Analyze the impact of the combination of Excavator and Dump Truck
on costs and time for the Phase II Bagong Dam Project Spillway work in
Trenggalek Regency. This research uses a descriptive qualitative approach. With a
case study type of research. The calculation results in this study show that for each
segment, several combination calculations were obtained where the recommended
alternative combination was most effective in terms of cost and work time. In the
calculation or selection of alternatives, it is determined by analyzing the capacity,
productivity and capabilities of the heavy equipment, which is then adjusted to suit
the needs of the Spillway work.
