Abstract

The purpose of this study was to: describe the level of application of office management and the level of performance of administrative staff at MTs Madani Alauddin, Gowa Regency. The type of research used is quantitative research with descriptive methods, and uses a management approach. The data collection method used a questionnaire distributed to 15 respondents. The data analysis technique used is descriptive statistical analysis. The results of this study indicate that the level of application of office management is in the medium category. Likewise, the performance level of administrative staff at MTs Madani is also in the medium category. The implications of this research are expected for madrasas so that in the future they can implement office management effectively and efficiently, in order to support the performance of administrative staff so that they have better performance than before. The implementation of office management in question includes planning for office work along with standard operating procedures, clear job descriptions contained in the organizational structure, providing training on office work procedures, as well as evaluating and evaluating work with rewards. As for administrative staff, in order to improve their competence, motivation and discipline so that they can achieve maximum performance.

Abstract

This study investigates the implementation of Extreme Value Theory (EVT) in modeling tail risk associated with employment injury insurance claims, addressing the critical need for robust risk estimation in the presence of rare, high-severity losses. The dataset consists of 1,177 historical claims from BPJS Ketenagakerjaan Makassar recorded between 2016 and 2023. Preliminary diagnostic procedures, including hill plots and mean excess function analysis, reveal heavy-tailed behaviour with a tail index greater than one, implying the possibility of infinite variance—a characteristic often underestimated by traditional actuarial models. Due to the limited number of extreme exceedances, the block maxima framework was adopted, and a Generalized Extreme Value (GEV) distribution was fitted to weekly maxima using L-moment estimation to ensure parameter convergence. The resulting GEV parameters (location = 50.27, scale = 67.19, shape = 0.443) confirm a Fréchet-type distribution, consistent with a heavy-tailed risk profile. Comparative analysis shows that the GEV-based 99.5% VaR (1,484.09 million IDR) is more than three times higher than the empirical estimate (450.56 million IDR). Return level analysis further contextualized the estimates, indicating a one-year return level of 768.51 million IDR. These findings demonstrate that empirical methods substantially underestimate extreme loss potential, potentially threatening insurer solvency. Overall, this study provides a statistically rigorous framework for capital reserve and reinsurance optimization, offering a more conservative and theoretically justified approach to managing catastrophic occupational risks.
