Abstract

Inventory of raw materials is very important for the smooth production of the company and meet consumer demand for the company in market demand. The demand for tire production fluctuates and causes the demand for products not to need to be met to order, due to the shortage of raw materials. To solve the shortage of raw materials, the company holds special orders in consideration of savings in ordering the cost of ordering messages. To overcome the shortage of raw materials, the company holds special orders or sudden orders which will increase the cost of the message. The purpose of this study is to determine the optimum ordering of raw materials to minimize total inventory costs by using a probability model of raw material inventory control with a fixed order quantity system (Q method). From the results of research using the probabilistic model of inventory control method Q method, obtained the optimal order quantity (q*), reorder point (rop), and safety stock (ss) with total inventory costs more efficient compared to the total inventory costs of the company's current policies. what is to be achieved in inventory control is to minimize the cost of ordering, and the cost of savings to the company.

Abstract

Balanced Scorecard (BSC) is an organizational performance appraisal model that emphasizes the measurement of financial and non-financial aspects as well as the result of a top-down process based on the mission and strategy of an organization. Performance appraisals with the Balanced Scorecard are translated into four perspectives: (1) Financial Perspective, (2) Customer Perspective, (3) Internal Business Perspective, and (4) Learning and Growth Perspective. The research method is identification of objective strategy and Key Performance Indicator (KPI), structuring KPI, weighting KPI using Analytical Hierarchy Process (AHP) method. The AHP method is the ability to accommodate interconnectedness between criteria or alternatives. Where there are 7 Objective Strategies and 10 KPIs translated within the framework of the AHP Strategy. This study discusses the measurement of corporate performance with the aim to improve performance (performance) by knowing the weight of each perspective, objective strategy and KPI. Based on the results of data processing obtained weight of each perspective are: Financial Perspectives 0.26, Customer Perspective 0.29, Internal Business Perspective 0.20, and Growing Perspective 0.26. From the results of the research shows that the weight of the Perspective of the Customer is greater than the other three perspectives.

Abstract

Automation is increasingly applied in food-processing industries to enhance production efficiency. However, in onion-processing operations, peeling machines often fail to completely remove the outer skin, requiring workers to perform manual re-peeling to ensure raw-material quality. This task involves repetitive hand motions and forward-leaning postures, which may contribute to musculoskeletal strain. This study aims to evaluate the work posture of manual onion re-peeling workers using the Nordic Body Map (NBM) and Rapid Upper Limb Assessment (RULA) methods. Four workers participated in the study through direct observation, photo documentation, and questionnaire administration. NBM results indicated that the most frequent complaints occurred in the the shoulders, upper arms, elbows, forearms, wrists, and lower back. The average RULA score of 6 indicates a high-risk posture requiring prompt ergonomic intervention. The strong alignment between NBM and RULA findings reinforces the accuracy of the ergonomic diagnosis. This study highlights the need for ergonomic improvements such as workstation height adjustment, provision of lumbar-supported seating, micro-break scheduling, and simple tool redesign to reduce MSD risks and improve productivity in food-processing operations.

Abstract

The production facility layout plays a vital role in enhancing the operational performance of Small and Medium Enterprises (SMEs). An SME in the Virgin Coconut Oil sector currently faces efficiency constraints due to an unorganized production flow. This Community Service Program (PKM) aims to redesign the SME's production facility layout to make it more effective, efficient, and compliant with sanitation standards. The implementation method consisted of three integrated stages: (1) field observation and problem identification, (2) designing a proposed layout using From-To Chart, Activity Relationship Chart and Activity Relationship Diagram instruments, and (3) socialization, design handover, and program evaluation. The result of this program is a new layout design featuring a U-shaped flow that minimizes material movement time while integrating ergonomic principles and work environment sanitation. Evaluation and feedback from the partner indicated a high level of acceptance, as the design successfully addressed the SME's operational needs. This redesigned layout is expected to serve as a strategic reference for related SMEs in optimizing production space and improving productivity sustainable.
