Abstract

This study investigates the performance and energy efficiency of a three-phase induction motor controlled by a Variable Speed Drive (VSD) in a fatty acid pump system at the Permata Group processing plant. The research is motivated by the increasing need for energy savings and operational reliability in continuous industrial processes where pump load profiles are highly dynamic. The objective of this study is to evaluate the effectiveness of VSD implementation in reducing energy consumption and improving motor operating characteristics under real plant conditions. Data were collected during actual production cycles through direct measurement of electrical and mechanical parameters, including current, voltage, frequency, torque, flow rate, and power consumption. The analysis compares the performance of the pump system before and after the application of VSD, using descriptive statistical analysis and graphical evaluation of motor behavior under various load conditions. The results demonstrate that the application of VSD significantly reduces energy consumption at partial loads while maintaining stable pump output and minimizing mechanical stress. The motor also shows improved operating efficiency and lower thermal loading compared to constant-speed operation. These findings indicate that VSD-based control offers a practical and cost-effective solution for industrial pump systems, especially in fatty acid processing operations where flow demand fluctuates during production. The practical implications are substantial, highlighting opportunities for energy conservation, equipment longevity, and process optimization without compromising product quality or throughput, making the system suitable for broader adoption in similar industrial environments.

Abstract

Driving safety has become a crucial issue in Indonesia due to the high number of traffic accidents caused by driver fatigue, particularly drowsiness that triggers microsleep and temporary loss of consciousness. This study aims to develop a driver drowsiness detection system based on Arduino Nano and infrared eye blink sensor that detects drowsiness indicators through blink frequency and duration, evaluates the effectiveness of early warnings via buzzer, and identifies technical constraints to enhance reliability in driving simulations. The research method employs a research and development approach with an experimental design, involving 15 participants aged 19-25 years tested in normal conditions and drowsiness simulations for 30 minutes per session, with data collection through eye blink sensor, Arduino Nano, and subjective validation using the Karolinska Sleepiness Scale. Testing shows the system achieves a microsleep detection accuracy of 98% based on eye closure duration exceeding 500 ms and 96% accuracy based on blink frequency below 12 times per minute, with an average response time of 178 ms until buzzer activation, thus capable of providing early warnings before full microsleep occurs. The implications of this research offer a portable, low-cost solution without reliance on complex infrastructure for mitigating accident risks in developing countries, although it still requires optimization against environmental variations such as lighting and head movements for real-world applications on the road.

Abstract

The use of rooftop solar power plants is one of the strategic solutions to support the energy transition and increase use of renewable energy in the industrial sector. This study aims to analyze the potential and performance of rooftop solar power plants at PT. Waruna Nusa Sentana building located in Medan City, North Sumatra, using a simulation approach based on HelioScope software. The analysis was carried out by utilizing Typical Meteorological Year weather data and technical parameters of the Photovoltaic (PV) system designed according geographical conditions and tropical climate of the study location. simulation results show that rooftop solar power system with an installed capacity of 47.36 kWp is capable of producing 66,699 kWh of annual electrical energy with a specific yield of 1,408.3 kWh/kWp/year. The system performance evaluation resulted in a performance ratio of 80.2%, indicating that the rooftop solar power system works efficiently and is in the good performance category for tropical regions. Loss analysis indicates that the largest energy losses come from the effects of cell temperature, followed by losses due to module mismatch, reflection, and losses in the inverter and AC system. Manual calculations performed as analytical verification demonstrated consistency with the simulation results, thus strengthening the validity of the approach used. This study demonstrates that the implementation of rooftop solar power plants in industrial buildings in Medan City is technically feasible and can be used as a reference in the planning and development of rooftop solar power plants in tropical regions with similar climate characteristics

Abstract

Hydropower plants (PLTA) remain the largest contributor to renewable energy generation capacity in Indonesia. As of October 2025, renewable energy generation capacity was recorded at 15,446.85 MW, with hydro contributing 6,539.17 MW and micro-hydro contributing 976.18 MW. Many micro-hydro locations operate in areas with limited access, so routine generator output checks are still often carried out through periodic visits to the location. Field observations reported in previous studies show that output conditions can fluctuate widely when there are load changes, including voltages from 160 V to 235 V and frequencies from 44 Hz to 51 Hz, which can potentially affect service quality and equipment operation. This study designed and implemented an Internet of Things (IoT)-based monitoring system to measure and report generator output voltage, load current, and frequency in real-time. The prototype integrates an ESP32 microcontroller, an AC energy measurement module, a local LCD display, and a cloud dashboard for remote visualization and time-stamped logging. The polling and transmission processes in the firmware are configured with a 5-second sampling interval to capture the dynamics caused by load changes while maintaining stable data delivery. Performance evaluation includes calibration against reference instruments, measurement of data update latency from acquisition to display on the dashboard, and tracking of transmission reliability through upload outcomes. The results of the study demonstrate a practical monitoring architecture, improve data availability for operators, and support operational decision-making without relying on frequent site visits.
