Abstract

The need for electrical energy that continues to increase in line with economic growth and community welfare demands optimal electricity distribution system reliability. Disruptions to the distribution network are often the main cause of power outages, which impact the quality of service to customers. PT. PLN (Persero) ULP Sinabang seeks to improve the efficiency and effectiveness of the distribution system to minimize blackouts and improve service quality. The evaluation of network reliability was carried out by analyzing the System Average Interruption Duration Index (SAIDI) and System Average Interruption Frequency Index (SAIFI) as the main parameters in measuring the performance of electricity distribution. The higher the value of these two indices, the worse the performance of the distribution system in maintaining the continuity of electricity supply. Through the analysis of the SAIDI and SAIFI values in 2023, this study aims to provide recommendations to reduce the rate of blackouts and improve the reliability of the power grid in the PT. PLN (Persero) ULP Sinabang.

Abstract

Load balancing on distribution transformers is an important step to improve the efficiency of electricity distribution and reduce power losses. Load imbalance between phases can cause an increase in neutral current, contributing to conductor power loss and financial loss. This research was conducted on the BR 114 distribution transformer at PT PLN (Persero) ULP Lembayung, with the aim of analyzing the impact of load balancing on neutral current, conductor power loss, and financial loss. The calculation results show that load balancing can reduce the neutral current from 150 A to 97 A, thereby decreasing the neutral conductor power loss from 2.00797 kW to 0.37129 kW. Financially, the savings obtained from load balancing amount to Rp 80,460,399. Thus, load balancing has proven to be an effective solution in reducing power losses and improving the efficiency of electricity distribution.

Abstract

This study discusses the overcoming overload problem in the distribution transformer that occurred at the SM01 Tie Line Sinabang ULP Sinabang Feeder. Transformer overload can lead to decreased electrical system performance, equipment damage, and potential power outages. The method used in this study is uprating, which is increasing the capacity of the transformer to meet the increasing load needs. The study begins with the analysis of historical load data and the identification of the factors that cause overload. Furthermore, simulations were carried out to evaluate the performance of the transformer under different load conditions. The uprating method is applied by taking into account the applicable technical specifications and operational standards. The simulation results show that increasing the capacity of the transformer can reduce the frequency of overload events and improve the reliability of the power supply. From the results of the study, it was concluded that the uprating method was effective in handling the problem of overload of distribution transformers at SM01 Feeder. Recommendations for the implementation of uprating and periodic monitoring of transformer conditions are also prepared to ensure operational continuity and safety of the electricity distribution system.

Abstract

Accurate door status detection and notification are essential for guaranteeing passenger safety and mitigating operational risks. Traditional car indicators, such as dashboard lights and basic whistles, offer little contextual information and frequently do not specify which door is ajar. Such constraints diminish the user's situational awareness, particularly when the driver is external to the car or in a cacophonous setting. This study presents an economical, embedded audio notification system for multiple doors, utilizing five normally closed push-button switches, an Arduino Uno microcontroller, a DFPlayer Mini MP3 playback module, an audio amplifier, and an 8-ohm speaker to deliver distinct voice notifications. MP3 messages in the Indonesian language are assigned to each door, facilitating unambiguous and contextually relevant feedback. The experimental findings demonstrate complete detection accuracy across 200 activation cycles. The device exhibits exceptional dependability, minimal power consumption, and straightforward integration, making it suitable for safety upgrades in aftermarket automobiles
