Abstract

PT. XYZ is a company that produces palm oil (CPO). In order to maintain the quality of sales, PT XYZ must be able to maintain the quality of what is stored in a storage tank called the Oil Storage Tank (OST). The aim of this research is to identify and analyze the factors that cause mutual problems in the quality of the bottom of the Oil Storage Tank (OST) and the most important thing is to reduce the pile of sludge that occurs due to the deposition process which cannot be recycled, thus causing a loss in the amount recorded in actually in the field when the Oil Storage Tank (OST) is washed. The more sludge deposits at the bottom of the tank, the higher the potential loss for the company. This research uses the PDCA (Plan, Do, Check, Action) method which based on the results of this research can reveal the impact of modifying the inlet pipe on the Oil Storage Tank (OST) on reducing the accumulation of sludge at the bottom of the Oil Storage Tank (OST) tank. The modification involves moving the pipe outlet to the middle of the bottom of the tank so that the sludge is distributed more evenly and makes it easier to suction when recycling it back to the processing process. As a result, the accumulation of sludge was reduced quite significantly from data from washing results in March 2023 of 23,430 kg and washing in January 2024 to 7,300 kg with a shelf life and total production of CPO (crude palm oil) stored in the Oil Storage Tank of around 20 thousand tons. over a period of 9 months.

Abstract

Small and medium-scale manufacturing industries generally face difficulties in minimizing their operational costs. The company's Make-to-Order strategy causes fluctuations in the number of jobs received, so it minimizes fixed costs such as labor wages. This phenomenon occurs in rectifier panel manufacturing companies and various other companies. Companies minimize the number of permanent employees and recruit daily contract employees. Unfortunately, daily contract employees are recruited when orders are received (t=0) so that employees are still paid even though work is not yet available. This study attempts to determine the timing of recruiting daily contract employees that is adjusted to the scheduled work. The method used is a combination of project management with the theory of constraints. The study focuses on three things, namely: (1) Determining the number of workers based on the workload in each position. (2) Conducting project scheduling using the PDM (Precedence Diagram Method) project scheduling method. (3) Applying the Theory of Constraint (TOC) method at problematic workstations so that product flow is balanced. The results of the study show efficient performance, namely: the number of workers decreased from 24 people to 17 people, and the duration of the project decreased from 171 working days to 94 working days
