PT. X is a company that has long been engaged in the glass manufacturing business and has several production plants. One of the plants of PT. X., which produces industrial glass have been had delivery lateness around 57% of all orders that have been received during January to May 2021. One of the factors that made lateness in delivery was came from the lack ability from Production Department to fulfil orders because the schedule for each machine did not made regularly. This research wishes to be able to give a scheduling improvement that can lower the rate of delivery lateness. The actual scheduling condition in that plant is done by manually moving the prioritized items  with Microsoft Excel program. This research will discuss the proposed Flexible Flowshop scheduling using Microsoft Excel VBA program with the objective function of minimizing the total weighted number of tardy jobs. The results of the proposed scheduling with the Microsoft Excel VBA program have a 25% better solution than the actual method. In addition, this method can shorten the working time of PPIC staff in generating scheduling for each machine.

Abstract

PT Anugerah Rimba Raya is a wood processing company that doesn’t have work hazard identification document. The company’s previous accidents report showed that there were 19 accidents that occurred from 2018 to 2020. The design of the HIRARC document aims to identify the types of hazards that can occur in the work environment, to evaluate the magnitude of the risks and its impacts, and to document the efforts of hazard control in order to minimize hazard potential.  The source of data collected during hazard identification stage will be carried out by direct observation, crew interviews, and company’s previous accident record. Futhermore, at the risk assessment stage, 2 parameters will be used, probability and severity. The assessment stage will divide hazard risk into different levels which is extreme risk, high risk, medium risk, low risk. After that, the risk control will be carried out based on the control hierarchy which is divided into elimination, substitution, technical design, administrative control, personal protective equipment. The prediction result of reduction risk levels after proposed controls showed a decrease in the level of risk that existed before.
