Arief Bagus Arjuna — 2026-07-13

Welding work in the workshop has potential hazards and high risks to occupational safety and health (OSH) such as sparks, exposure to ultraviolet radiation, toxic fumes, hand cuts, and electric shocks. One risk control effort is the use of personal protective equipment (PPE). Therefore, a job safety analysis (JSA) method is needed to identify hazards in a structured manner at each welding stage to determine the need for appropriate PPE. These potential hazards can trigger work accidents and occupational diseases such as eye injuries and respiratory disorders. This study aims to identify potential hazards at each stage of welding work using the JSA method. This study is a qualitative descriptive study with a JSA approach. Data collection was carried out through direct observation such as material preparation, pipe adjustment, welding process, and interviews with workers or welders. The analysis was carried out in several steps, namely identifying potential hazards at each step, and determining PPE recommendations that meet standards. Based on the JSA worksheet, several potential hazards include burns due to sparks during the welding stage and eye injuries due to pipe debris during the finishing stage. The results of the analysis show a gap between the PPE recommended by the JSA and that actually used in the field. Workers often neglect the use of PPE, such as respirators and leather aprons, due to discomfort and limited inventory in the workshop. The JSA method can map specific hazards and establish appropriate PPE requirements for each welding stage. Workshop management is advised to use the JSA sheet as a standard operational guide, provide PPE according to JSA recommendations, and conduct a safety briefing before work begins.

This research focuses on the analysis of the quality control system in the refining process of Crude Palm Oil (CPO) at PT XYZ, with the aim of minimizing the level of Free Fatty Acid (FFA) in Refined, Bleached, and Deodorized Palm Oil (RBDPO) products. The quantitative approach applied is based on the Six Sigma methodology through the DMAIC cycle (Define, Measure, Analyze, Improve, Control). The evaluation of the process is strengthened by triangulation of data sourced from field observations, structured interviews, internal documentation, and the company's historical track record. In the Define phase, process mapping is carried out through SIPOC diagrams and Critical to Quality (CTQ) determination. The Measure phase involves measuring stability through the P control map as well as calculating the values of DPU, DPO, DPMO, and sigma capabilities. Next, the Analyze phase utilizes Pareto and Fishbone diagrams to identify the root cause of the problem. Based on the findings, the average out-of-spec FFA product throughout 2025 will reach 2.9%, with a DPMO value of 9,752.3232 and a performance level of 3.87 sigma (equivalent to the national industry average). The main triggering factors for this failure come from human, machine, method, material, environmental, and measurement aspects. As a solution, in the Improve stage, recommendations based on 5W+1H were prepared which included tightening raw material supervision, maintenance of vacuum and steam spurging systems, updating SOPs, periodic instrument calibration, and operator training. Finally, the Control stage is designed to ensure the consistency and stability of the quality of RBDPO at PT. XYZ on an ongoing basis.
