Abstract

The rapid development of the industrial world has made it a necessity for companies to compete with their competitors. Therefore, companies must control the quality of their products well, one of which is by analyzing defective products. The purpose of this research is to analyze the level of defects in Toolbox products produced by PT KSKB and provide improvement suggestions to reduce the level of defects in PT KSKB Toolbox products. This research uses data on the number of productions and the number of defective products obtained through field observations and interview processes. The method used in this research is the Seven Tools and Kaizen Five-M Checklist method of improvement analysis. Based on the data processing results, there are three types of defects in Toolbox products: burrs, materials with holes, and cutting with no precision. The most frequent type of defect is burrs (an uneven surface of the object due to the working process), with a value of 52.12%. Meanwhile, from the analysis of the Kaizen Five-M Checklist, periodic training (training and OJT) needs to be conducted for employees, routine machine maintenance needs to be carried out, standard operating procedures need to be evaluated, and work areas need to be evaluated to create a safe and comfortable working environment so that the level of product defects can be reduced.

Abstract

In the increasingly competitive automotive industry, effective raw material control is essential to achieve cost efficiency, maintain production continuity, and ensure accurate distribution. PT XYZ, an automotive manufacturing company located in Karawang, faces several challenges, including high demand fluctuations, dependence on imported raw materials, and the absence of safety stock calculations, which increase the risk of inventory shortages. This study aims to determine the optimal raw material planning method by integrating demand forecasting and Material Requirement Planning (MRP) using the Lot for Lot (LFL) technique in the production of the KWU-type Timing Chain Cover (TCC). This research employs a quantitative case study approach, with data collected through observation, interviews, documentation, and literature review. Demand forecasting is conducted using Double Exponential Smoothing, Moving Average, and Linear Regression methods. The most accurate forecasting method is then used as an input for preparing the Master Production Schedule (MPS) and MRP. The results indicate that the Linear Regression method provides the highest forecasting accuracy, as indicated by the lowest Mean Squared Error (MSE) value of 2,075,786,061. Furthermore, the implementation of MRP using the Lot for Lot technique combined with safety stock calculations proves effective in reducing the risk of stockouts. This improvement is reflected in the stabilization of inventory levels, such as the water pump bearing component, which previously experienced zero stock conditions and is now maintained at a safety stock level of 37,770 units. In conclusion, the integration of Linear Regression forecasting and Lot for Lot-based MRP enhances planning accuracy, ensures raw material availability, and supports long-term operational efficiency at PT XYZ.

Abstract

Improving teacher quality is a strategic element in improving the quality of national education. However, various structural and systemic challenges still hinder the optimization of teachers' roles in Indonesia. This study aims to identify the main challenges in improving teacher quality and analyze the efforts made through government policies to address these challenges. The research method used is library research, involving the review of various academic literature, policy documents, and relevant research reports. The results of the study show that the main challenges include disparities in teacher competencies and qualifications, uneven distribution of teachers, especially in 3T (frontier, outermost, and disadvantaged) areas, lack of continuous professional training and development, high administrative burdens, and low teacher welfare and motivation. Analysis of government policies indicates that despite the existence of various programs such as teacher certification, the Teacher Development Program, and the digitization of training, their implementation still faces numerous obstacles. In conclusion, improving teacher quality requires more holistic, integrated, and sustainability-oriented policies, as well as equitable access to professional development.

Abstract

PT XYZ is a manufacturing company in the paper industry with a continuous production system, making machine reliability a critical factor in maintaining smooth processes and high product quality. A vital system within the Cutter Strachain Henshain Machine (SHM) is the tension measurement system, which regulates paper web tension during the handling process. Field observations at PT XYZ revealed recurring disturbances caused by tension reading failure, which created significant discrepancies between Human Machine Interface (HMI) readouts and actual paper web conditions. While Reliability Centered Maintenance (RCM) is widely studied, its application to vintage, highly sensitive paper-tension control loops operating continuously for over two decades represents a distinct socio-technical operational gap. This study aims to analyze the maintenance strategy of the SHM tension measurement system using the RCM method to address this critical gap. Using a descriptive empirical approach incorporating structured observation, historical maintenance logging, and technical interviews, the system's operational functions, functional failure, and failure modes were systematically mapped. The analytical findings demonstrate that the primary point of failure stems from localized sensor contamination and localized degradation, severely compromising tension reading accuracy. Implementing an RCM-guided maintenance strategy, specifically through scheduled condition-directed maintenance and structured functional testing, is recommended. Quantitative projections indicate that these interventions can reduce total machine downtime by up to 15.4%, optimizing continuous production stability and mitigating cascading cutting defects.
