Abstract

Delays in detecting damage and potential theft of public street lighting remain a common problem in several areas due to reliance on manual reporting systems. Therefore, this study aimed to design and develop an Internet of Things (IoT)-based system for security monitoring and early detection of damage in public street lighting. The proposed system employed an ESP8266 microcontroller, a Light Dependent Resistor (LDR) sensor to detect lamp operating conditions (on/off), and an E18-D80NK infrared proximity sensor to detect object presence as an indication of theft. Monitoring data were transmitted in real time and displayed through the Blynk application as the user interface. The research method included hardware and software design, system implementation, and functional testing, including LDR sensor testing, infrared proximity sensor testing, and system delay evaluation. The experimental results showed that the system accurately detected lamp operating conditions during testing on a 22-watt street lamp and successfully detected objects with a 100% detection rate. Delay testing indicated that the system response time increased with object distance but remained within acceptable limits for monitoring applications. Overall, the developed system was effective in supporting monitoring, early damage detection, and improving the security of public street lighting.

Abstract

This research was conducted during an Industrial Internship at PT Sumarah Energi with the objective of analyzing power losses in a 1.5 megawatt synchronous generator Unit 1 at the Logawa Baseh 1 Mini Hydropower Plant. The generator functioned to convert mechanical energy from the turbine into electrical energy; however, power losses occurred during operation, reducing the effective output power. The analysis was carried out by collecting generator specification data, stator current, excitation current, and daily load data during August 2025. The data were quantitatively analyzed through calculations of copper losses, core losses, mechanical losses, and stray load losses. The results showed that copper losses were the largest component of power losses, ranging from 15.12 to 21.25 kilowatts and increasing with higher stator current. Core losses of 9.19 kilowatts and mechanical losses of 6.12 kilowatts remained constant, while stray load losses contributed the smallest portion, ranging from 0.15 to 0.21 kilowatts. The total power losses ranged from 30.58 to 36.77 kilowatts and were mainly influenced by load variations caused by fluctuations in river water discharge. This research demonstrated that daily load variations significantly affected total power losses, particularly copper losses, while core and mechanical losses remained stable in synchronous generators used in mini hydropower plants.

Abstract

As A Tropical Country, Indonesia Frequently Experiences Extreme Weather, One Of Which Is Lightning, Which Has The Potential To Harm Humans And Electrical Infrastructure, Particularly On High Voltage Overhead Lines (Sutt). Sutt Play A Crucial Role In The Distribution Of Electrical Energy, But Are Vulnerable To Natural Disturbances That Are Difficult To Control. Lightning Strikes Can Damage Equipment And Reduce System Reliability, Necessitating Effective Protection, Such As Grounding Towers, To Channel Lightning Currents To The Ground. The Research Phase Began With A Literature Review, Examining Theories, Standards, And Previous Research Related To Grounding Systems And Lightning Protection On Transmission Lines. Next, Field Data Was Collected, Including Data On Lightning Disturbances On Sutts, The Existing Condition Of Tower Grounding Systems, And The Types Of Protection Installed. Afterward, Grounding Resistance Measurements Were Conducted On Several Towers To Determine The Quality Of The Existing Grounding System. The Results Showed That The Multi-Direct Grounding Method, With An Average Resistance Value Of 2.89 Ω On The 150 Kv Star-Rawalo-Majenang Sutt, Met Standards And Was Proven Effective In Protecting Towers From Lightning Disturbances, Minimizing The Risk Of Damage Due To Back Flashover, And Improving Transmission System Reliability

Abstract

Circuit Breaker (PMT) is an important equipment in the electric power system that functions to break and connect the current both under normal conditions and when a disturbance occurs, so that the reliability and safety of the system are highly dependent on the quality of the operation of this device. One of the critical parameters that must be met is the simultaneity of inter-phase contacts so that transient conditions, overvoltages, and unbalances can be minimized. This study aims to determine the results of the simultaneity test on the 150 kV PMT Bay Transformer 3 Lomanis Substation to assess the reliability of its operation and its compliance with technical standards. The test method is carried out through simultaneity analysis based on the results of measurements of inter-phase contact operation time in open trip and close conditions, as well as statistical analysis using the One-Sample T-Test test through SPSS software. The measurement results show that the highest inter-phase time difference only reaches 0.90 ms, far below the SKDIR 0520 standard limit of 10 ms. Statistical test results support these findings, with the Time Open Trip parameter having an average of 27.9833 ms with a significance level of 0.910 (p > 0.05) and the Time Close Trip having an average of 65.8000 ms with a significance level of 0.094 (p > 0.05). Both values ​​indicate no significant difference from the standard. Therefore, the PMT in Transformer Bay 3 of the Lomanis Substation is declared to be operating synchronously, reliably, within the required tolerance limits, and suitable for supporting power system reliability.
