Analysis of safety cost structure for electrical work in rental apartements projects in special capital district of Jakarta based on Work Breakdown Structure (WBS)

With the lack of rental housing needs still very large, the need for building rental apartments in the future is still very high. In the implementation of construction projects in Indonesia in general the number of work accidents also increased. The construction industry is a dangerous industry that often takes its toll. Referring to the Manpower Social Service Provider (BPJS) data, nationally the number of occupational accidents in the construction sector is recorded as the highest national sector work accident rate. Especially in electrical work, there are many work accidents during electrical work that endanger electrical workers. For this reason, it is necessary to make a simulation of SMK3 cost modeling in order to estimate the costs needed with minimum project information at an early stage. Activity-based cost calculation has emerged as a new approach that connects costs directly related to business activities with manufactured products. To make activity-based cost calculations, making WBS and determining work items appropriately is a useful effort and is needed for effective activity-based risk assessment. So based on the above findings, given the high plan of building rental flats, the high number of occupational accidents and the lack of comprehensive OSH funding, this study focuses on developing OSH costs for the electrical component work in rental flats in DKI Province. Jakarta-based WBS.
