    Analysis of Technical Anomalies in Power Supply AMR Using FMEA at PT. PLN Batam
    (2025-08-06) Perdana, Ikhsan; Octowinandi, Vivin
    — The Automatic Meter Reading (AMR) system plays a crucial role in the efficient collection of electricity consumption data at PT. PLN Batam. However, the reliability of this system is frequently disrupted by recurring damage to the AMR device's power supply, leading to failures in accurate and real-time data transmission. This study aims to identify the primary failure modes, analyze their root causes, and formulate mitigation strategies to enhance the reliability of the AMR power supply. Through a combination of fishbone analysis, Failure Mode and Effect Analysis (FMEA), visual inspection, and component measurements, it was found that the two most significant failure modes are the continuous operation (24 hours) of the power supply and exposure to high ambient temperatures. The FMEA results showed Risk Priority Numbers (RPN) of 175 for frequency of use and 245 for temperature, highlighting the urgency of addressing both factors. Specifically, visual inspection and capacitance measurements confirmed that the 220uF electrolytic capacitor is the most vulnerable component, exhibiting significant capacitance degradation due to high temperatures and non-stop operation, which leads to unstable output voltage and frequent modem restarts. Based on these findings, the study recommends power supply PCBA rework, specifically replacing the faulty capacitors, as a cost-effective repair solution. Furthermore, as a preventive measure, the implementation of an active cooling system within the PLN APP box and the use of an external timer to regulate the operational cycle of the power supply and modem are proposed. Although the preventive recommendations have not yet been implemented due to cost and time constraints, this research provides a deep understanding of the root causes of AMR power supply issues and offers practical solutions to improve system performance and customer satisfaction at PT. PLN Batam.

    Failure Analysis of Econo Dual Module Frame Installation in The Automatic Frame Assembly Process
    (2025) Stifen Tama Tamba Stifen Tama Tamba; Nakul,Fitriyanti
    In the modern manufacturing era, process automation plays an important role in increasing efficiency and product quality. One of the main components in automation is the Automatic Frame Assembly Process which has a crucial role in installing the frame on the Econo Dual module because it uses robot power to carry out this process, and this certainly follows existing parameter provisions and uses certain programs on the machine. Econo Dual Module is a product resulting from the production of this machine which is used as the object of this research. This research aims to identify the main cause of the high failure rate of frame installation on the Econo Dual module using the Root Cause Analysis (RCA) method and find the solutions to handling the problems. By using a fishbone diagram and 5 Whys analysis, several causes of failure to install the frame on the module were found, including there is no NTC components on the module (which is the main cause and problems that often occur), the presence of bubbles and discontinuity gluing on the module, damaged frame, and solder spatter on the module. After knowing the several causes of the failure, the author found various solutions to minimize the problem according to the provisions of how the problem occurred individually
