On Wednesday, December 21, 2022, the Faculty of Public Health (FPH) at the Universitas Indonesia (UI) held an open session for the promotion of the doctoral degree in Public Health Sciences (IKM) with promovendus Lelitasari. Acting as Chair of the Session as well as Chair of the Examining Team are Prof. dr. Fatma Lestari, M.Si., Ph.D., with Prof. Dr. dr. L. Meily Kurniawidjaja, M.Sc., Sp.Ok., as Promoter accompanied by Prof. Dr. dr. Sabarinah, M.Sc., and Dr. Robiana Modjo, S.K.M., M.Kes., as co-promoter. While the examiner team consisted of Prof. dr. Purnawan Junadi, Ph.D.; drg. Baiduri Widanarko, M.K.K.K., Ph.D .; Dr. Lana Saria, S.Si., M.Sc.; Dr. dr. Sudi Astono, M.S.; and Dr. Ronny Pardomoan Tambunan. At this virtual meeting Lelitasari defended her dissertation entitled “Study of the Development and Implementation of Fatigue Risk Management Performance Assessment Instruments in Coal Mining Companies in Indonesia in 2022”.
“Fatigue in mining operations is a serious issue and a significant contributor to accidents. By law, companies that operate coal mines must develop and implement strategies to control any safety and health risks associated with worker fatigue,” said Lelitasari in her dissertation presentation.
Her research aims to develop performance assessment instruments for fatigue risk management in coal mining companies in Indonesia. The study approach used is a combination of qualitative approaches to find performance indicators and quantitative to test the validity, reliability, and quality of fatigue risk management performance assessment instruments in coal mining companies. The samples taken were 90 coal mining companies in Indonesia. This study then produced a fatigue risk management performance assessment instrument in coal mining companies consisting of 31 indicators, with the validity and reliability of the instrument having met the requirements.
The results of the ROC curve analysis obtained a cut-off point of 73 and an AUC of 71.3%, which means that the Fatigue Risk Management (MRK) performance score has moderate predictive power for accidents due to fatigue. It was found that the performance of fatigue risk management in coal mining companies was 45.6% poor and 54.4% good. The fatigue risk management performance category with the poor category is most common in companies with <1,000 employees, namely 60.9%. From the type of company permits, the category of fatigue risk management performance in the good category was mostly found in companies with the IUJP permit type, namely 80% and the unfavorable category, the most in companies with the Production Operation IUP permit type, namely 73.7%. It was found that there is a relationship between fatigue risk management performance and the number of employees and the type of company permit.
Through the results of this research, it is hoped that the Ministry of Energy and Mineral Resources of the Republic of Indonesia and coal mining companies in Indonesia can use fatigue risk management performance assessment instruments to assess, monitor and evaluate fatigue risk management performance in coal mining companies.
Based on the results of her dissertation, Lelitasari was successfully declared a doctorate in the field of Public Health Sciences. Lelitasari is a graduate of the 276th Doctoral Study Program in Public Health Sciences and the 356th graduate of the Doctoral Study Program at FPH UI. (wrk)
