Abstract

The electricity supply crisis is still a major problem in various remote areas in Indonesia, which has a negative impact on economic growth, education, and community welfare. To overcome this problem, the use of renewable energy such as Microhydro Power Plants (PLTMH) is one of the relevant and sustainable solutions. This study aims to analyze the role of microhydro in overcoming the electricity supply crisis, as well as identifying supporting and inhibiting factors in its implementation. The research method used is a qualitative-descriptive approach with data collection techniques through literature studies, interviews, and field observations in areas that have developed PLTMH. The results of the study show that microhydro is able to make a significant contribution to the provision of electricity independently in areas that have not been reached by the PLN network. In addition, active community involvement in the management and maintenance of PLTMH is a key factor in the success of this program. However, challenges such as limited funds, lack of technical support, and operational sustainability issues are still major obstacles. Therefore, synergy between the government, community, and private sector is needed to encourage the development of microhydro as a long-term solution to overcome the electricity supply crisis in remote areas.

Abstract

The rising cost of electricity due to the dependence on fossil fuels has become a significant burden for households in Indonesia. Rooftop Solar Power Systems (PLTS Atap) emerge as a potential clean energy solution to address this problem. This study aims to analyze the effectiveness and economic feasibility of implementing Rooftop Solar as an effort to reduce household electricity bills. This study applies a mixed-method (quantitative-qualitative) approach through surveys and interviews with 25 households with 1300 VA or higher electricity service. The quantitative analysis results show that for an average monthly consumption of 329.1 kWh, a 3 kWp solar power system is highly recommended. This system has the potential to cut monthly bills by up to 95.7% with a payback period of approximately 8.5 years, although it requires an initial investment of around IDR 46,250,000. However, the qualitative findings reveal that the majority of respondents (56%) are hesitant due to this initial investment cost. Meanwhile, another 20% of respondents were neutral, indicating a need for more information and accessible financing schemes. This study concludes that although Rooftop Solar is highly feasible from a technical and economic standpoint, its main barriers are socio-economic. The success of future adoption heavily depends on the availability of accessible financing models to overcome the initial capital challenge.

Abstract

The demand for renewable energy in Indonesia continues to increase in line with the government's efforts to promote a sustainable energy transition. One of the rapidly growing technologies is On-Grid Solar Power Plants (PLTS), which rely on solar energy as their primary source. However, variations in solar irradiation and environmental factors cause fluctuations in the system's performance, potentially affecting its efficiency and reliability. Therefore, a robust method is needed to accurately predict system performance, supporting maintenance and operational optimization. This study applies the Seasonal Autoregressive Integrated Moving Average (SARIMA) method as a time series analysis approach to predict the Performance Ratio (PR) of PLTS based on historical data and solar irradiation variables. SARIMA was chosen because stationarity tests revealed a significant seasonal pattern that conventional ARIMA models cannot effectively handle. By considering seasonal factors, SARIMA provides a more accurate estimation of PR trends and fluctuations. This research aims to detect potential anomalies early, identify recurring operational patterns, and improve PLTS system monitoring efficiency. Model evaluation results show that SARIMA has higher accuracy than ARIMA in capturing seasonal patterns in PR data. Implementing this model can assist PLTS operators in making more data-driven decisions, optimizing maintenance strategies, and ensuring the reliability of renewable energy systems. These findings contribute to the development of more efficient energy management strategies and support the sustainability of solar energy utilization in Indonesia.

Abstract

Maha Vihara Duta Maitreya Monastery, Bukit Beruntung, Sungai Panas, Batam Kota is one of the places of worship for Buddhists that has a large number of visitors, especially during Vesak. The increase in visitor frequency also consistent with an increase in candle sales, especially lotus candles. Lotus candles be used as a symbol of illumination, purity, life, inner cleanliness, or a sacrifice. The use of large lotus candles results in an increase in the volume of wax waste. Used wax waste can have a negative impact on the environment if not processed properly. Because of the potential negative impacts caused by piles of wax waste, researchers are processing the available waste to be able to reuse wax waste. Through the processing of waste candles, recycled functional candles were obtained with various variations such as almond, brick, brick & brick pink and others that allow lighting within ± two hours. Thus, this research has contributed to efforts to increase public awareness through the action of reducing the volume of waste through reprocessing into recycled products that have a selling value in the community according to the principles of circular economy.

Abstract

Electronic devices are generally powered by a power source such as an AC socket or a DC power source such as a battery. Batteries have a limited lifespan, so it is necessary to recharge the battery if the battery is rechargeable. In this paper we present a design for an independent power system where the power does not come from an AC voltage socket, but the power is obtained from the results of radio frequency energy harvesting. The selected frequency is the frequency for cellular that emitted from the Cell Phone Operator's Base Transfer System. The Radio Frequency Energy Harvesting system catch RF signal use monopole antenna receiver, then the RF signal converted into DC voltage (RF to DC converter) by a series of charge pump that also serves as amplifier which designed to 5-stage villiard multiplier. This system integrated by boost regulator to raise the level of voltage and regulate constant voltage. The voltage result from system is 300 mV at 100 m from BTS and 3,9 V at 30 cm from mobile phone. Another test with a LED indicator and suplying a power for charging process to battery AAA rechargeable Ni-MH.

Abstract

The increasing demand for reliable long-distance electricity transmission has elevated the importance of understanding corona discharge phenomena in high-voltage AC (HVAC) and DC (HVDC) transmission lines. Corona discharge, caused by local electric fields exceeding air breakdown strength, contributes to power losses, audible noise, and electromagnetic interference, which collectively reduce system efficiency and operational reliability. This study investigates the behavior of corona under varying environmental and conductor conditions, focusing on pressure, humidity, and surface roughness, which are known to influence onset voltage, power loss, and noise emissions. A combination of empirical modeling and regression-based analysis was employed, incorporating effective breakdown field estimations, geometric voltage scaling, AC/DC mode corrections, and power-law relationships for corona current and power loss. Experimental and simulation results demonstrate that the breakdown field is maximized at 3.0 MV/m under high pressure (105 kPa) and low humidity (10%), while decreasing to 1.9 MV/m at 80 kPa and 95% humidity. Corona onset voltage decreases with surface roughness, with AC voltage dropping from 72.0 kV to 56.4 kV and DC voltage from 78.0 kV to 61.2 kV over roughness ranges of 0.5–50 ?m. Power losses scale with excess voltage, with AC losses following and DC losses . Audible noise increases from 24 dB(A) to 71 dB(A) as power loss rises, with surface roughness and humidity amplifying the effect. Sensitivity analysis identifies surface roughness and humidity as dominant factors, while AC lines exhibit 14% higher power losses and 13% higher noise levels than DC lines. The findings provide quantitative insights for transmission line design and operational policies, emphasizing the need for surface maintenance and humidity mitigation strategies to enhance efficiency, reduce energy losses, and comply with environmental noise standards.

Abstract

Transformers are one of the most important equipment in electrical power systems. Transformer failure at power plants can interrupt the continuity of electricity supply. Therefore, monitoring the condition and early detection of transformer damage is important to ensure that transformers can work properly until their maximum service life. One type of damage that can occur is a change in the mechanical structure of the transformer's internal components. This damage can be detected using the Sweep Frequency Response Analysis (SFRA) method, which is a non-invasive testing technique that analyzes changes in frequency response due to internal mechanical disturbances. This study conducted an SFRA analysis on power transformers at the Tenayan Raya Power Plant by comparing the conditions before and after repairs. Comparisons across three test periods showed that the most notable variations occurred between 2020 and 2022, mainly at high frequencies, indicating winding deformation due to operational stress. In contrast, the pre- and post-maintenance comparison revealed stable responses, confirming that maintenance activities did not cause significant deformation.
