Abstract

This study aims to analyze the implementation of Material Requirement Planning (MRP) method in controlling raw material inventory for aluminum wardrobe production in Amal Jaya SME. The inability to accurately predict the average number of customer orders each month indicates unfulfilled consumer demand. Therefore, effective raw material control becomes crucial to ensure availability in accordance with demand. The objectives of this research are to evaluate the management of raw materials using the MRP method and identify its impact on cost efficiency of raw materials in the production process. Additionally, this study aims to optimize raw material inventory to maximize customer demand fulfillment. The MRP method was chosen as the primary approach in this research. The results of the analysis indicate that the implementation of MRP method with Lot for Lot (LFL) lot sizing is the most efficient choice in controlling raw material inventory. Based on calculations using lot-for-lot and Economic Order Quantity (EOQ) methods, the most efficient inventory expenditure incurred by the company amounts to Rp. 26,274,840. Thus, ordering raw materials with Lot for Lot lot sizing can be used as a solution to optimize the control of aluminum wardrobe inventory in Amal Jaya SME.

Abstract

PDAM Gowa, a local government-owned company, plays a vital role in supplying clean water to the Tompobulu community in Gowa District. However, ensuring efficient and reliable water distribution poses challenges at the local and regional levels. This research focuses on enhancing the resilience of the water distribution system to mitigate various risks. The study utilizes the House of Risk (HOR) method for effective risk management and developing suitable mitigation strategies within PDAM's framework. The research identifies 10 risk events and 17 risk factors that affect water distribution in PDAM. Key risks include pipe leakage and supply disruptions. To mitigate these risks, the study proposes nine actionable recommendations for PDAM Gowa Unit Tompobulu. These recommendations involve regular maintenance of distribution infrastructure and equipment to ensure system quality and reliability. Additionally, improving pipe network condition monitoring, implementing leakage control policies, and fostering collaboration with stakeholders to address water supply disruptions are crucial mitigation measures. This research significantly contributes to understanding the risk management associated with water distribution in PDAM. By implementing the recommended mitigation strategies, PDAM Gowa Unit Tompobulu can reduce water distribution risks, enhance system efficiency, and provide improved clean water services to consumers. Moreover, the study has the potential to drive scientific progress and promote the development of best practices and technologies in the drinking water industry.

Abstract

This study evaluates the performance of human resources at PT. Wanxiang Nickel Indonesia (WNI), is influenced by a lack of responsibility, low awareness of work risks, and insufficient employee skills. The research method employed is the Human Resources Scorecard (HRS), involving a Likert scale for Key Performance Indicators (KPI) and Pairwise Comparison in the Analytical Hierarchy Process (AHP). The results of the study indicate the highest weight is found in the perspective of employees' intellectual competence (1.079) and work competence (0.981), followed by emotional competence (0.303) and personality competence (0.246). This research aims to improve human resource (HR) performance and productivity within the company. The intellectual and work perspectives play a significant role in the evaluation, while emotional and personality perspectives also contribute meaningfully. Recommendations: the company needs to develop these perspectives in a balanced manner to enhance overall human resource performance and productivity at PT. WNI.
