Electrical energy continues to grow over time, power plants with large capacities are the main sources of electricity in Indonesia, one of which is the Steam Power Plant (PLTU). In the field of power plants that use coal always need air during the electricity production process. This study aims 1) to determine the protection management system on the Forced Draft fan motor using GE Multilin 269 Plus, 2) Setting GE Multilin 269 Plus as protection, 3) The results of the protection in the form of Normal Motor, Alarm, and Trip conditions in the accumulation of imbalance (Unbalance) ). The method used is a quantitative research method based on analysis, taking data and then analyzing the data obtained. The results of this quantitative study regarding the Unbalance value or imbalance of the electric motor analyzed resulted in a value of 5.8% for normal conditions, 10.86% for alarm conditions on multilin and 15.50% in trip conditions or the motor had stopped. These values ​​are obtained from the results of calculations comparing negative sequence currents and positive sequence currents (In/Ip). The conclusion obtained is that the GE Multilin 269 Plus protects the electric motor from system damage by using a current sensor and through a setting point that is adjusted to the provisions of NEMA (National Electrical Manufacturers Association) with an unbalance value of more than 15% for trips, more than 10% for alarm conditions and less than 10% under normal conditions

Abstract

The advancement of digital technology has had a significant impact on broadcasting production systems, including at Radio Republik Indonesia (RRI) Banten. This study aims to examine the performance of the vMix Pro application in improving production efficiency and the quality of digital broadcast programs at RRI Banten. The research employed a descriptive qualitative method, with data collected through field observations, interviews with broadcast technicians, and literature studies. The results indicate that the implementation of vMix Pro increased production time efficiency by 50%, reduced operational costs by 40%, and decreased the number of required technical operators from five to three. In terms of quality, both video and audio outputs showed improvement, achieving an average score above 4.6 on a 5-point scale, reflecting more stable, clear, and professional broadcasts. With its user-friendly interface and high device integration capability, vMix Pro has proven effective in streamlining workflows, optimizing resource utilization, and enhancing the overall production quality of broadcasts at RRI Banten

Abstract

This research discusses the design and construction of an automatic mineral water refilling system using fuzzy logic based on the ESP32 microcontroller. The background of this research is the increasing environmental pollution due to the use of disposable plastic mineral water bottles in the campus environment. The system is designed to be able to fill water containers automatically with IR sensor-based control and ultrasonic sensors to detect the presence of containers and water levels. The research method used is the Waterfall method which includes the planning, design, implementation, and system testing stages. The test results show that the system is able to fill water with an average effective volume of 83.2 % of the container capacity, with a safe limit for automatic stopping at a distance of less than 2 cm from the rim of the container. The implementation of Mamdani fuzzy logic allows the system to make filling decisions based on sensor conditions adaptively, resulting in efficient and accurate pump control. Thus, this system can be an innovative solution to reduce plastic waste while supporting efficient water use in the campus environment.

Abstract

The research aimed to evaluate the accuracy of control system simulations using MATLAB Simulink by comparing the results with those from reference journals. This study employed simulations and comparative analysis without any hardware testing. The system model and control parameters were derived from the reference journal, and simulations were conducted to obtain the system response in the form of time-domain waveforms. The analysis focused on comparing key system response characteristics, including target point attainment speed, overshoot, and steady-state stability. The results revealed that the waveform of the simulation response closely matched the patterns observed in the reference journal, with a high degree of agreement in terms of response characteristics. MATLAB Simulink simulations were validated as a reliable tool for system response analysis, as the small differences observed did not significantly impact the overall conformity of the response characteristics. This study confirms that MATLAB Simulink is effective for validating control system performance based on reference journal simulations.

Abstract

The Low Voltage Main Distribution Panel (LVMDP) is a critical component in industrial power distribution systems, functioning to regulate, control, and distribute electrical energy to various production equipment. During operation, LVMDP panels often operate under high electrical loads, which may lead to temperature increases in their components. Undetected temperature rise can result in performance degradation, equipment failure, and even fire hazards. Therefore, an effective monitoring method is required to detect the condition of electrical components at an early stage. This study aims to analyze the temperature difference (ΔT) of LVMDP components using the Infrared Thermography method as part of predictive maintenance. The research employs a quantitative descriptive approach with data collected through direct observation from July 1 to July 31 at PT. Dongjin Indonesia. The data consist of hotspot and ambient temperatures measured from several panel components, which are then analyzed to calculate the temperature difference (ΔT) as an indicator of component operating conditions. The results indicate that the highest temperature difference is 26.5 °C in the capacitor bank, while the lowest is 4 °C in other components. All ΔT values are below the threshold limit of 50 °C, indicating that the LVMDP components are in safe operating conditions and do not require corrective actions. Thus, Infrared Thermography is proven to be an effective method for early detection of component conditions and can enhance the reliability and safety of industrial power distribution systems.

Abstract

This study designs and implements an up-down counter system based on an AT89C2051 microcontroller programmed in assembly using the MC-51 application. The system modifies an existing digital clock board by mapping the display selector pins, seven-segment segment pins, pushbuttons, and buzzer to the microcontroller ports. The research method consists of literature review, hardware identification, algorithm design, assembly programming, program downloading, and functional testing using a 5 V DC supply. The implementation uses a four-digit common-cathode seven-segment display and a multiplexing routine to show the counter value in real time. The functional test shows that the system can display the initial value, increase the value through the up button, and decrease the value through the down button. The display is readable during operation, and the program can run on the target circuit after being downloaded to the AT89C2051. This study confirms that assembly programming on MC-51 can be applied to implement a simple counter system on a reused digital clock circuit. The main limitations are the absence of explicit button debouncing, overflow and underflow protection, quantitative response-time measurement, and non-volatile data retention.
