Abstract

Risk management at CV Budidaya Jamur Sejati is very important to avoid defects in mushroom cultivation caused by failures in the cultivation system. Risk analysis is also important to avoid failures that may occur in the oyster mushroom cultivation system. In this study, the integrated FMEA method was used to analyze the oyster mushroom cultivation process at CV Budidaya Jamur Sejati During the period from December to January 2025, CV Budidaya Jamur Sejati experienced cultivation failure at the maintenance stage, producing 5kg to 7kg of mushrooms. CV Budidaya Jamur Sejati does not yet know the types of risks faced in the mushroom maintenance process. FMEA is applied to the mushroom process to identify the main failure risks and sort all risks related to potential cultivation failures. There are 7 root causes of failure identified in the cultivation process. The results obtained from the application of the FMEA method indicate that this information can be used as a preventive and corrective step to minimize the failure of the mushroom cultivation process.

Abstract

PT. Dalwa Anugrah Hasaniyah's water production still relies on human power to carry out its production activities. At PT. Dalwa Anugrah Hasaniyah has a section for producing mineral water which is processed manually in a bending and standing position. Activities in the bottle washing section to the machine are (1) inserting labels into bottles, (2) lifting bottles containing water into cartons, and (3) moving cartons containing mineral water to pallets. The activities carried out by workers have a high risk and cause complaints of pain. To overcome this problem, it is necessary to carry out work posture analysis to assess and evaluate worker posture. Based on the results of the Nordic Body Map questionnaire, workers experienced complaints in the waist, spine and secondary areas. The REBA assessment results show the first activity with a score of 6, meaning the activity has a moderate risk of musculoskeletal disorders so improvements need to be made as soon as possible. Meanwhile, the second and third activities have scores of 10 and 11 respectively, which means that these two activities have risks that need immediate action for further investigation and changes.
