Background: One of the important nickel extraction processes is mixing nickel ore into Dry Ore Storage (DOS) material as the main intake of Kiln Reduction. To ensure mixed material quality, DOS Sample House operators regularly takes sample and test the homogeneity of samples manually. Material handled by lifting some buckets moved to be mixed, then 1/8 of mixed sample tested and 7/8 disposed. This test activity takes 15 minutes each for 35 samples in one shift. The aim of this study was to evaluate posture, determine the prevalence of work-related musculoskeletal disorder and fatigue of DOS Sample House II workers. Method: A random sampling method according to mining work activity type was used to obtain the sample. Total of seven workers data was collected by using Nordic Body Map for symptoms and subjective workload using Rating of Perceived Exertion (RPE) questionnaire; after they finished all tasks of their shift. Four out of 25 tasks in one test were selected (reject sample removal tasks) and assessed using Rapid Entire Body Assessment (REBA). Results: The mean age of seven workers was 37,4 years, all men, and they worked for 4,2 years on average. In one sample test, material needed to be lift were average 28,81 kg which above the recommended weight. The highest prevalence of work-related musculoskeletal disorder symptoms were lower back, right forearm, buttock, right shoulder and hip. RPE scored range was 4 to 7 that their work makes them sweat a lot and REBA scored range 8 to 10, which the risk is high, need investigation and immediately implement changes. Conclusion: The overall finding indicated that the process of selected tasks, reject sample removal task, will contribute to musculoskeletal disorder either for a short or long time exposure.

ISO 21001:2018 is an international standard for the management system of educational organizations that formal education organizations can apply to achieve their goals and functions to provide quality educational services. Currently, there are study programs with C accreditation and 2 study programs accredited B at Faculty of X under The University of Y. Hence, quality assurance at Faculty X still needs to be improved to achieve the highest accreditation. It is hoped that an education management system that refers to the ISO 21001:2018 standard can assist organizations in meeting these goals and targets. Faculty X has not implemented the ISO 21001:2018 quality assurance system but has implemented a quality assurance system through an internal academic quality audit process known as AIMA. This study aims to determine the GAP between the current higher education quality assurance system and the educational organization management system ISO 21001:2018 and determine the level of readiness obtained by Faculty X to meet the requirements of ISO 21001:2018. The results show that 59% of the ISO 21001:2018 clauses have been completed in the higher education quality assurance standard based on AIMA (Academic Quality Internal Audit Instrument), and 41% of the requirements still do not meet the AIMA standard. The percentage of readiness obtained by Faculty X in implementing the management system of educational organizations ISO 21001:2018 is 73%, which means that Faculty X still has to improve the quality system in preparation for ISO 2100:2018 quality assurance. Improvements in meeting the ISO 21001:2018 educational organization management system are plans for consistent improvement, monitoring, and evaluation.
