Abstract

In the modern industrial world, conveyor systems are important components that support the efficiency and sustainability of the production process. The use of induction motors as conveyor drives has become the main choice because of its durability, energy efficiency, and relatively low operational costs. This study aims to analyze the performance of induction motors, especially three-phase induction motors, in belt conveyor systems in industrial environments. The method used is a quantitative descriptive approach by analyzing technical parameters such as motor power, efficiency, power factor, torque, and operational and maintenance data. The results of the study show that a three-phase induction motor with a power of 1.5 kW provides more stable and efficient performance than a single-phase motor of 0.75 kW, both in terms of energy consumption, torque efficiency, and operational efficiency. The efficiency of the three-phase motor is recorded at 88% with energy consumption of ±85 kWh per month in a work cycle of ±200 hours. With a maximum torque of 6.0 Nm, the motor is able to overcome inertia loads optimally. It is concluded that the selection of three-phase induction motors that are in accordance with the needs of the conveyor system can improve energy efficiency and extend the operational life of industrial equipment.

Abstract

Public Street Lighting (PJU) based on Solar Power Plants (PLTS) is one of the renewable energy solutions that is starting to be widely applied in Indonesia, especially in areas that have not been reached by conventional electricity networks. This study aims to examine the environmental and social impact of the implementation of PJU PLTS in two regions with different characteristics. The method used is qualitative descriptive with the support of quantitative data, through interviews, observations, and questionnaire dissemination. The results of the study show that PJU PLTS is able to reduce carbon emissions, improve the visual quality of the night environment, and create a safe and productive space for the community. Social impacts include increasing a sense of security, growing night-time economic activities, and strengthening the social cohesion of citizens. However, challenges such as lack of technical education and community participation are still to be found. This study recommends increasing citizen involvement, battery waste management, and strengthening project sustainability monitoring. These findings reinforce the importance of a sustainable and inclusive approach in renewable energy projects at the local level.

Abstract

The problem of limited energy and high household electricity consumption in Indonesia encourages the importance of implementing energy-efficient lighting technology. The still high use of energy-wasting incandescent lamps indicates the low energy literacy of the community in choosing efficient types of lamps. This study aims to analyze and compare the energy efficiency of three generations of lamp technology, namely incandescent lamps, compact fluorescent lamps (CFLs), and LED lamps, with an experimental approach. Testing was carried out using a wattmeter, lux meter, and infrared thermometer in a closed room with controlled conditions. Each type of lamp was tested with a light output equivalent to ±800 lumens. The test results showed that LED lamps had the lowest power consumption of 10 watts with the highest efficiency of 80 lumens per watt and a surface temperature of 45°C. CFLs have a power consumption of 15 watts with an efficiency of 53.3 lumens per watt and a temperature of 70°C. Meanwhile, incandescent lamps consume 60 watts with an efficiency of only 13.3 lumens per watt and a surface temperature of 120°C. Simulation of household use shows that the use of LEDs can save electricity costs of up to 112,500 rupiah per month compared to incandescent lamps. The results of this study provide empirical evidence that LEDs are the most efficient lighting solution in terms of energy, cost, and safety of use for the household sector.

Abstract

Biannual preventive-maintenance results (2022 & 2024) for the 150 kV Tanjung Pura line bay circuit breaker at Pangkalan Brandan Substation confirm reliable performance. Offline tests with Kyoritsu 3125 (5 kV) and ISA CBA-2000/Megger evaluated insulation resistance, contact resistance, operating time and contact synchronization against SPLN 52-1:1984, KEPDIR 0520-2.K/DIR/2014 and OEM limits (≤120 % FAT, ≤120 ms for 150 kV). Insulation far exceeded 1 MΩ/kV: 315–428 GΩ (62 600–85 600 MΩ/kV) in 2022 and 181–190 GΩ (36 200–38 000 MΩ/kV) in 2024; the drop is within safe bounds and linked to instrument variance and insulator surface condition. Contact resistance stayed low at 36.0–38.7 µΩ (<40 µΩ), although resistive loss rose from 0.13–0.139 W to 0.435–0.468 W due to higher load current. Opening time was 37.3–38.9 ms and closing time 68.2–72.6 ms, both compliant. Contact synchronization measured 0.3–0.8 ms open and 3–3.4 ms close, well below the 10 ms limit. The breaker is operationally healthy. Recommendations: periodic instrument calibration, pre-test insulator cleaning, strict adherence to SOPs and safety standards, and improved crew coordination for future consistency and safety.

Abstract

The three-phase induction motor stands as the predominant choice in industrial applications due to its numerous benefits. To optimize its performance, maintaining the integrity of the motor's power supply is essential. A significant factor influencing power quality is the load applied to the motor. This research focuses on analyzing and calculating the power consumption of a three-phase induction motor under varying control valve opening conditions, ranging from 10% to 100%. The motor under study operates as a pump driver, facilitating the transfer of sweet water in the fatty acid production facility at PT Unilever Oleochemical Indonesia. Key parameters examined include variations in current, power factor, and input power. Findings indicate that when the valve opening varies from 10% to 100%, the motor’s power output reaches up to 106% of its rated capacity at full valve opening. Conversely, at the minimum valve opening, the motor’s efficiency drops to 67.9% relative to its nominal power.
