OPTIMASI PENJADWALAN DAN ANALISIS BEBAN KERJA PADA PROYEK PEMBANGUNAN KAPAL IKAN FIBERGLASS 1 GT

Abstract

This study aims to analyze project scheduling using Work Breakdown Structure (WBS) and Critical Path
Method (CPM) to determine the sequence and duration of activities in the construction of a 1 GT fiberglass
trimaran fishing boat, as well as to evaluate the workload of workers through Workload Analysis (WLA).
The study was conducted at the non-metal workshop of the Shipbuilding Institute of Polytechhnic Surabay
using direct observation and interviews with workers involved in the production process. The results of the
CPM application show that the critical path is in the A-B-C-D-K-L series of activities with an estimated
project completion time of 28 days. The WLA analysis showed a labor productivity rate of 90.48% for Non
Metal Workshop PLPs and 85.71% for Non-Metal Workshop Technicians, but both were in a state of
overload, at 133.27 and 156.98, respectively. These findings confirm that although schedule planning and
work allocation can be effective, adjustments to the number of workers are needed to maintain long-term
productivity. In general, the research results can be used as a reference in planning future fiberglass
trimaran shipbuilding projects.
