Abstract

Uncontrolled raw material inventory can lead to either excess or shortage of stock, thereby hampering the production process. This condition is also experienced by CV. Arafah Jaya, a manufacturer of window and door frames, where frequent stockpiling of raw materials results in high inventory costs. This study aims to systematically plan raw material requirements using the Material Requirement Planning (MRP) method. Demand forecasting was carried out using the Moving Average and Exponential Smoothing methods, with the evaluation showing that Exponential Smoothing produced more accurate results. The forecasting data were then used to develop the Master Production Schedule (MPS) as the basis for calculations in the MRP system. The analysis continued with the application of three lot-sizing techniques, namely Lot for Lot (LFL), Economic Order Quantity (EOQ), and Period Order Quantity (POQ). The comparison results indicate that the LFL technique yields the lowest total procurement cost of raw materials, amounting to IDR 7,290,380. Thus, the LFL technique is considered the most efficient method for controlling raw material procurement at CV. Arafah Jaya.

Abstract

A safe and comfortable work environment plays a crucial role in maintaining employee health and productivity, especially in the textile industry, which is characterized by repetitive and physically demanding tasks. This study aims to identify the Critical Control Points (CCPs) of physical environmental factors—namely temperature, lighting, and noise—and analyze their effects on work-related stress. The research employed direct measurements of environmental conditions and distributed questionnaires to 68 respondents selected through random sampling. Data adequacy tests confirmed that the sample size was representative. CCP analysis revealed that temperature and noise levels in several work areas, particularly in the Extruder and Dryer sections, exceeded regulatory thresholds and were thus classified as critical control points. In contrast, lighting levels remained within acceptable limits. ANOVA testing produced a significance value of 0.000 and an F-value of 13.181, indicating a significant influence of physical environmental factors on work stress. Therefore, it can be concluded that controlling temperature and noise is essential to reducing stress risks, improving workplace comfort, and supporting worker productivity in the textile industry.

Abstract

Increasingly competitive industrial conditions necessitate that companies maintain high product quality to remain competitive. One of the challenges frequently faced by the manufacturing industry is high levels of product productivity, which can impact customer satisfaction and operational efficiency. This study specifically examines the issue of product defects in the car seat production process at PT. ABC. Despite implementing a quality control system, a significant number of product defects were still found. The study used a quantitative approach using Statistical Quality Control (SQC) methods, specifically p-charts, to analyze production and defect data over 16 days. The analysis showed that the proportion of defects varied significantly, with the highest value reaching 55.17% and the lowest at 5.13%. The control chart showed data points approaching the upper control limit, indicating the process was not yet fully stable. Fishbone analysis identified the main causes of defects, including human factors, work methods, raw materials, and machines. Comprehensive improvements to the work system and joint control are needed to increase production process stability and sustainably reduce defect rates.

Abstract

The fierce competition of the global industry, operational efficiency is crucial for a company's competitiveness, and optimal facility layout can reduce production costs and accelerate cycle times. From-to charts are used to evaluate and optimise material or product flow. The From-To-Chart method is a traditional way to review and improve material or product flow. Its primary focus is to identify and measure material movement within the factory work area. Based on an initial analysis of the radiator seal production flow at PT. XYZ, efficiency remains low. Initial forward efficiency stands at 74.25%, below the optimal target of 75%. Meanwhile, backward efficiency reaches 25.75%, indicating significant unnecessary and repetitive material movement. This situation arises because certain areas, such as the laboratory and NMI zone, are visited more than once during a single production cycle. The analysis results show an improvement from 74.25% to 98.01%. Its primary function is to identify and calculate material movement moments within the industrial layout, thereby enhancing efficiency and effectiveness during operational time.

Abstract

Dalwa Anugrah Hasaniyah, a manufacturing company, produces bottled drinking water (AMDK). One of the main machines used in the production process is the 600 ml bottle filling machine, which plays a crucial role in ensuring smooth production. However, in actual use, this machine often experiences problems that reduce production efficiency. The most common problems include delays in raw material deliveries, which cause downtime or interruptions in the production process, as well as breakdowns of certain machine components. Decreased productivity and increased production costs are the consequences of this scenario. Using the Overall Equipment Effectiveness (OEE) method, which consists of three main indicators—availability, performance, and quality—this study aims to measure and evaluate the effectiveness of the 600 ml bottle filling machine. Research data was obtained over a period of six consecutive weeks through direct recording of machine operating hours, the number of products produced, defective products, and downtime. The results of data processing indicate that the average OEE value of the filling machine is 78%. This value is still below the world-class OEE standard of 85%. The main factor influencing the low OEE value is the high level of downtime, which significantly impacts the decline in availability, where the average availability value obtained is only 80%. This study concludes that the company needs to implement a scheduled preventive maintenance strategy, increase the reliability of raw material supplies, and optimize operator skills to improve machine effectiveness and approach world-class standards.

Abstract

The furniture industry is one of the manufacturing sectors that makes a significant contribution to the economy. However, the complexity of the production process, ranging from raw material procurement to product distribution, makes this industry vulnerable to various internal and external risks. If not properly managed, these risks may hinder production targets, reduce product quality, and weaken the company’s competitiveness. This study aims to identify and design risk mitigation strategies in a furniture business in Yogyakarta using the House of Risk (HoR) method. Data were collected through observation and questionnaires to assess risk events and risk agents. The HoR phase 1 analysis identified nine risk events and twenty-two risk agents, with five priority risk agents, namely raw material shortages due to poor planning, suboptimal maintenance, limited raw material stock from suppliers, delays in machine spare parts procurement, and lack of worker skills. Subsequently, HoR phase 2 produced five main mitigation strategies, including improving raw material requirement calculations, establishing clear maintenance schedules, expanding supplier networks, enhancing interdepartmental coordination, and providing worker training and certification. The findings indicate that the application of the HoR method can assist furniture companies in prioritizing risk sources and formulating more systematic and targeted mitigation strategies.

Abstract

The growing demand for housing in Palembang has encouraged people to purchase homes through the Mortgage Ownership Program (Kredit Pemilikan Rumah/KPR). The complexity of the purchasing decision arises from the many factors that must be considered, such as building type and quality, location, price, and environmental conditions. This study aims to identify the main criteria in selecting KPR housing in Palembang and to determine the priority of each criterion. The method employed is the Analytical Hierarchy Process (AHP), with a case study conducted at PT. Rama Trimitra Development Group. Research data were collected through questionnaires distributed to expert respondents consisting of developers, architects, and banking representatives. The results show that the environmental criterion is the top priority with an average weight of 0.2962, followed by location, price, and building type and quality, which ranked the lowest. These findings are expected to assist prospective homeowners in making better purchasing decisions and to serve as a reference for developers in designing KPR housing products that align with consumer expectations.
