Abstract

Risks are present in every activity and could cause damage if not properly addressed. This research discusses how to identify risks that occur in the production process of the food industry. The characteristics of the goods, such as flavor, price, appearance, and availability, are met through the production process by transforming raw materials into products. The XX Bakery business experiences several risks at the production stage that reduce the quality of the product which potentially causes financial losses. Failure Mode and Effect Analysis (FMEA) is used to identify and assess the risks and their level of importance. There were 20 risks that occurred in the production process obtained through observation and interviews. The risks were then assessed based on severity, occurrence, and detection through a questionnaire to determine the Risk Priority Number (RPN) value. The Pareto chart shows which risks would result in a significant impact if given treatment. There were top 5 risks in which RPN values resulted in 80% of the total score. The risks are broken mixer with a score of 360, fluctuation of raw material prices with a score of 320, power outages with a score of 240, workers experiencing fatigue with a score of 144, and water supply stopped with a score of 60. The risks were then further analyzed using Fault Tree Analysis (FTA) to find their root causes. The results of the risk management processes serve as a base for consideration in forming proposals for corrective actions that improve risks—the implementation of the proposed improvements is expected to reduce losses that potentially be experienced by the business.

Abstract

PT. XYZ is a company that produces plywood. The issue faced by this company is the increasing risk of defective plywood products resulting from the production process. This research conducts a risk analysis of rejected defective products using the Statistical Process Control (SPC) method to identify the types of defects and their causes, as well as the Failure Mode and Effect Analysis (FMEA). Based on production data from January 2022 to April 2023, PT. XYZ Samarinda has produced 6,629,815 plywood pieces, with 356,137 rejected defective products. There are 10 types of defects, namely delamination defects, blisters, 2x process fractures, impacts, cores that are too narrow, patches, defective sander F/B, F/B too narrow, defective press F/B, and uneven cores. The results obtained from the SPC method indicate that there are four priority defect types: delamination defects, blisters, 2x process fractures, and impacts. According to the FMEA method, the most risky cause for delamination defects is applying a layer of adhesive that is too thin, with an RPN value of 280. The most risky cause for blister defects is an excessively high adhesive dose, with an RPN value of 180. The most risky cause for 2x process fractures is excessive pressure during the core scratching process that penetrates the F/B, with an RPN value of 210. The most risky cause for impact defects is careless workers when moving plywood lots using a cart, with an RPN value of 144. Subsequently, improvement proposals are made using the 5W+1H method to determine the causes of defects and the necessary improvements that the company should undertake.

Abstract

PT Bustani Bersaudara is an LPG gas distribution agent company. Gas distribution activities are carried out by a driver who delivers gas to the delivery destination. However, after conducting interviews with drivers, some drivers felt some problems such as feeling a little tired from driving for a long period of time, and the type of work that is monotonous and requires high concentration during work makes drivers feel mental workload. Based on these problems, will calculate the mental workload, work fatigue, and sleep quality of drivers and analyze the influence between mental workload and sleep quality on work fatigue in drivers. The methods used in this study include NASA-TLX to measure mental workload, PSQI (Pittsburgh Sleep Quality Index) method to measure sleep quality level, and IFRC (Industrial Fatigue Research Committee) method to measure work fatigue level. The measurement results of the NASA-TLX method obtained an average mental load of 74.956 which is classified as a moderate mental workload category. The PSQI method obtained the average result of sleep quality level of 9.9 which is classified as a low sleep quality category. The IFRC method obtained the average result of work fatigue level of 57.4 which is classified as mild work fatigue category. The effect of mental workload on work fatigue obtained a significance value of 0.251, which means that mental workload has no effect on work fatigue because the significance value is > 0.05. The effect of sleep quality on work fatigue obtained a significance value of 0.345, which means that sleep quality has no effect on work fatigue because the significance value is > 0.05. Simultaneously, the effect of mental workload and sleep quality on work fatigue produces a significance value of 0.145, which means they simultaneously have no influence.
