<![CDATA[The transformer is a crucial component in the electrical energy distribution system. Therefore, strict supervision is necessary to ensure that the electricity supply network is maintained and safe during operational processes. This research aims to measure the transformer load installed at PT. Sunrise Steel to determine the values of loading, imbalance, power losses, and efficiency of the loaded transformers. This measurement is important to ensure that the values resulting from operational processes do not exceed predetermined limits. Observations over 10 days show that the peak load value during operational time is 66.08%, which can still be categorized as quite good. The load imbalance reached a maximum value of 10.13%, which is categorized as poor since SPLN regulations state that a good imbalance should be below 10%. The percentage of power loss has a maximum value of 0.33%, and the best transformer efficiency reaches 97.17%, which is the highest efficiency value considering several other loss parameters.]]>

<![CDATA[This study aims to comprehensively evaluate the potential, technical, and economic feasibility of implementing a hybrid solar-wind power generation system as a sustainable energy solution to support the operation of Electric Vehicle Charging Stations (EVCS) in Pangandaran Regency, Indonesia. Through simulations using HOMER Energy software, this research analyzes the renewable energy resource potential in the region, with an average solar radiation of 5.03 kWh/m² and an annual wind speed of 5.03 m/s. The simulation results show that the optimal system configuration consists of 335 solar panels (113.9 kWp) and 6 wind turbines (9 kW), capable of generating 177,791 kWh of annual electricity, which is sufficient to meet the energy needs of the EVCS with a reasonable margin. The economic analysis conducted indicates that although there is a significant initial investment cost, the hybrid system has a Net Present Cost (NPC) of IDR 5,825,862,785 with a Cost of Energy (COE) of IDR 2,245/kWh, demonstrating that this investment offers long-term economic benefits. Furthermore, the sensitivity study performed shows that the system is relatively robust to changes in environmental conditions and other system parameters. The results of this research provide strong evidence that the hybrid solar-wind power generation system is technically, economically, and environmentally viable for supporting the development of electric vehicle charging infrastructure in areas with high renewable resource potential, such as Pangandaran. The implementation of this system is expected to reduce dependence on fossil fuels, lower greenhouse gas emissions, and promote the transition towards clean and sustainable energy in Indonesia]]>

<![CDATA[Global environmental issues are becoming more pressing with the increasing volume of plastic waste and the decline in fossil fuel resources. According to a report from the United Nations Environment Programme (UNEP), more than 300 million tons of plastic are produced annually, and around 50% of it is single-use plastic. This study aims to evaluate the effect of adding methanol to biogasoline from pyrolysis of plastic waste on an Otto engine, in this case a carburetor motorcycle. Plastic waste processed through pyrolysis produces biogasoline, which is then mixed with methanol in concentrations of 20% (BM20) and 30% (BM30). This test was carried out using a dynotest machine to measure power, torque, and air fuel ratio (AFR) in the engine speed range of 1000 to 7500 rpm. The results showed that the addition of methanol had an effect on increasing engine performance, especially on the power and torque produced. At 20% methanol concentration, engine power increased up to 5500 rpm before decreasing at 7500 rpm, while at 30% concentration, power increased from 200 rpm and began to decrease at 6700 rpm. Meanwhile, AFR showed a stable tendency at the beginning of engine speed with a significant decrease at high speed, especially in BM30. For AFR, BM30 produced more stable combustion at low speed but experienced a drastic decrease at high speed, with the air-fuel ratio reaching an imbalance above 7000 rpm. This study contributes to the development of alternative fuels based on plastic waste that are more efficient and environmentally friendly. The addition of methanol has been shown to improve the combustion quality of biogasoline, although further optimization is needed to achieve consistent performance across all engine speed ranges.]]>

<![CDATA[The electrical power system requires reliability to provide good and stable services. Each area has a variety of load characteristics related to the energy patterns of users in that region. As the solution, optimizing power flow in the interconnected system is necessary to improve reliability, quality, and system stability. This study aims to determine the impact of load variations on system stability. The simulation results indicated that the power flow at bus 1 and bus 2, directly connected to the generator, got stable balance. Specifically, bus 1 had an active power of 144 kW and a reactive power of 102 kVAr, while bus 2 had an active power of 54 kW and a reactive power of 54 kVAr. The comparison of active power with the motor constant of 100%-0% static showed that the highest value at load 1 reached 37.12 kW. Similarly, the comparison of reactive power with a motor constant of 80%–20% for the static constant showed that the highest value, achieved at load 6, was 19.2 kVAr. Thus, the simulation is beneficial to analyze the sensitivity in optimizing power flow within the electrical power system and can serve as a reference for future research.]]>
