Abstract

Workers in the rigid foam block weighing area at PT IIA are exposed to ergonomic risks due to repetitive manual tasks and non-ideal working postures. These conditions can lead to musculoskeletal complaints and increase the risk of Musculoskeletal Disorders (MSDs). This study aims to design and develop an ergonomic digital weighing device using a load cell sensor to reduce occupational risks and improve production process efficiency. Postural analysis using the Rapid Entire Body Assessment (REBA) method was conducted to evaluate ergonomic risks prior to equipment design. The weighing tool was designed based on workers' anthropometric dimensions and tested to ensure weight measurement accuracy through calibration and sensor linearity testing. The test results show an average error rate of only 0.024%, which falls within the acceptable tolerance limits of the sensor. Therefore, the digital weighing device is considered ergonomic, accurate, and feasible for use in the production process.

Abstract

The manual process of submitting Work Order Forms (FPK) in the Engineering Section causes various obstacles such as late delivery, difficulty in recording, and low efficiency and data accuracy. This study aims to design and build a digital system in the form of a Kodular-based Android Application to make it easier for tenants to make work order requests to Engineering. The user interface is designed using the draw.io tool and the backend system uses PHP and MYSQL. This application allows users to access information and submit work requests practically through mobile devices. Test results show an increase in time efficiency of 70.36% and cost efficiency reaching 82.43% compared to the manual system. In addition, features such as the Complaint Form, Dashboard, Satisfaction Survey, Instructions and Profiles help speed up the user flow and minimize the risk of data loss. This system has also been tested using the black box method and shows good results. Thus, this digital system effectively supports digital transformation in engineering work processes.

Abstract

This research aims to design and develop a web-based material supply information system to address delays in material delivery at the PPC Plant D Department of PT PCR. The previous system relied on Microsoft Excel with macros, which was considered inefficient due to its lack of real-time data updates. The new system was developed using PHP Native with a MySQL database and tested using the blackbox method. The results showed that the system could automatically display real-time material delivery data through features such as auto-refresh, auto- scroll, and search functionality. Additionally, the responsive interface allows for easier monitoring of delivery schedules between production departments. The implementation of this web-based system has proven to increase efficiency and effectiveness in material delivery to the Building process, reducing the average delay caused by material factors from 6.276% to 2.27%. Therefore, the web-based information system effectively improves the distribution process of materials in a manufacturing environment.
