Abstract

This research aims to increase production efficiency at UD Cantenan, an aluminum metal manufacturing industry, through the application of the Systematic Layout Planning (SLP) method, the Kanban system, and Work Sampling productivity analysis. The initial layout shows the material movement distance between workstations is 41 m², with daily material handling costs reaching IDR 105,544. Through the SLP method, the layout was improved so that the moving distance was reduced to 37 m², and material handling costs fell to IDR 70,626 per day. The Kanban system was implemented to visually improve production flow, minimize waiting time, and reduce inventory buildup. Kanban implementation increased product delivery accuracy from 70% to 95%. Furthermore, productivity analysis using Work Sampling showed a non-productive activity ratio of 53% and productive activity reaching 65%. Normal production time measurements yield an average of 14 minutes per unit, indicating increased work efficiency. A total budget plan for implementing relayout of IDR 5,203,000 was also prepared as part of company resource management. The results of this research show that the combination of SLP, Kanban, and Work Sampling methods can significantly increase operational efficiency, optimize facility layout, and reduce production time and costs.

Abstract

The optimal implementation of Occupational Safety and Health (OSH) is a crucial aspect in ensuring worker safety and maintaining smooth production processes in the sugar processing industry. At PG Madukismo, there were 23 recorded work accidents during the 2022 milling season, which increased to 45 cases in 2023, with 7 incidents occurring in the milling station. The rise in accident rates is attributed to workers' non-compliance with safety procedures, such as the use of Personal Protective Equipment (PPE), and substandard working environment conditions. This study aims to identify potential hazards and analyze work risks at the milling station of PG Madukismo using the Job Safety Analysis (JSA) method. The method involves breaking down each work activity, identifying hazards, assessing risk levels based on likelihood and severity, and determining appropriate control measures. The results show that several work activities pose high-risk levels, primarily due to excessive noise, mechanical hazards from milling machines, and inadequate lighting. These findings underscore the need to enhance supervision, provide OSH training, and improve workplace conditions to establish a safer, healthier, and more productive work environment.

Abstract

CV Cahaya Setia Mulia Abadi is a manufacturing industry that produces sports gloves made of leather and synthetic materials. The golf glove product of the Brance brand studied from January 9-29, 2025 had a high defect rate of 1135 units so that improvements needed to be made to reduce defects in its production. Quality control is carried out through the Six Sigma approach using stages and a number of methods such as SIPOC, P Control Chart, Fishbone Diagram, and 5W + 1H. The purpose of this method is to identify the type of product defect, find out the cause of the defect, and formulate appropriate improvement efforts. FMEA analysis is also applied to identify potential failures based on the highest RPN value. At the define stage, 4 types of defects are known to be processed using the CTQ diagram, namely open stitches, holes, damaged variations, and asymmetrical. The next stage is measure which produces a CL value of 0.04668, UCL 0.051, and LCL 0.04262. The analysis of the analyze stage shows that the source of defects comes from human factors, machines, methods, materials and the environment. The potential causes of defects were further analyzed through FMEA with the highest RPN of 168, with the type of open stitch defect. In the improve stage, a proposal for corrective actions was prepared for all factors. In the control stage, efforts were made to ensure that corrective actions could be implemented consistently and effectively.

Abstract

Indonesia is the largest palm oil producing country in the world. Every ton of processed oil palm fruit yields approximately 230 kg of empty fruit bunches (EFB). Currently, only about 10% of the EFB generated by the palm oil industry is utilized, while the rest remains as waste. This has prompted researchers to explore ways to optimize its use, one of which is converting EFB into activated charcoal.. The aim of this study is to examine the effect of phosphoric acid concentration on the quality of activated charcoal made from EFB. The research consists of two main processes: the carbonization of EFB and the activation of the resulting charcoal using phosphoric acid as an activating agent. The concentrations of phosphoric acid used for activation were 6M, 7M, 8M, 9M, and 10M.. Based on the results, the activated charcoal produced at all acid concentrations met the Indonesian National Standard (SNI 06-3730-06). The best quality activated charcoal was obtained using 10M phosphoric acid, with quality parameters including a moisture content of 7.76%, ash content of 6.55%, and an iodine adsorption capacity of 1,011.60 mg/g.

Abstract

Data reveals that at UMKM Tahu Prapto, out of 9,450 tofu products produced, 1,016 products were defective, indicating quality control issues in August 2024. By implementing the six sigma method, it is expected to identify defects to determine the company's sigma value, so that the company can improve its sigma value to compete in the market and provide improvement recommendations aimed at reducing the existing product defects in Tahu. In its implementation, six sigma has 5 (five) steps to improve business performance, namely define, measure, analyze, improve, and control, so that problems or opportunities, processes, and customer requirements must be verified and updated at each step. Further analysis using the Pareto diagram identifies specific defects in the tofu product, such as dirty tofu, incorrect size, unpleasant texture, and bad odor. The proposed improvements include scheduling regular equipment cleaning, ensuring the maintenance and cleanliness of production machines, and maintaining a clean working environment to prevent contamination of tofu products

Abstract

This study aims to analyze the influence of the Work From Home (WFH) system and work motivation on the performance of internship students at the Bakti Milenial Foundation. The background of this research lies in the shift of work patterns during the pandemic era, where many organizations and institutions implemented remote work systems, including internship programs. This shift is expected to affect the way students carry out their tasks, adapt to technological facilities, and manage work discipline. In addition, motivation is considered an important internal factor that drives students to work more effectively and productively, regardless of the working system applied. This research adopts a quantitative approach with an explanatory research method to test the causal relationship between variables. The population of this study includes all internship students at the Bakti Milenial Foundation, while the sample was selected using a snowball sampling technique involving 30 respondents. Data collection was carried out using questionnaires distributed online through Google Forms. The collected data were then analyzed statistically to determine the extent of the effect of the independent variables, namely WFH and work motivation, on the dependent variable, namely student performance. The results of this study reveal two main findings: (1) The Work From Home system has no positive and significant effect on the performance of internship students at the Bakti Milenial Foundation. This finding suggests that the flexibility of remote work does not automatically improve student performance, possibly due to limitations in supervision, communication barriers, or challenges in maintaining focus. (2) Work motivation has a positive and significant effect on the performance of internship students. This indicates that intrinsic and extrinsic motivation play a crucial role in driving students to complete their tasks effectively and responsibly.

Abstract

The biomass-fueled Steam Power Plant (PLTU) at PT Pelindo Multi Terminal presents a relatively high potential risk of occupational accidents due to the use of flammable fuel, extreme pressure and temperature conditions, and the complexity of operational equipment. This study aims to identify potential hazards, assess risk levels, and provide mitigation recommendations using the Hazard and Operability Study (HAZOP) method. Data were collected through field observations, interviews with workers and supervisors, as well as a review of operational documents and accident reports. The analysis revealed several major risks, including fire, explosion, steam leakage, exposure to toxic gases, and accidents caused by equipment failure. Risk assessment using the HAZOP matrix identified several critical points, particularly during the biomass combustion process, high-pressure steam treatment, and turbine operation. The risk levels ranged from moderate to high, requiring planned and systematic mitigation measures. Recommended strategies include strengthening temperature and pressure control systems, implementing regular maintenance and inspection of equipment, ensuring proper provision and use of personal protective equipment (PPE), enhancing worker capacity through occupational safety training, and installing early detection systems for fire and gas leaks. The implementation of these recommendations is expected to minimize workplace accidents, improve worker safety awareness, and support the creation of a safer, more efficient, and sustainable working environment in the operation of the biomass steam power plant.
