Abstract

Along with the increasing use of electrical energy and air pollution, one of which is caused by fossil fuel resources, has encouraged an increase in the use of renewable energy, especially solar power. Solar Power Plants (PLTS) have become an attractive alternative, especially for industrial and residential needs because they can reduce the cost of conventional electricity bills. At the design stage of the Solar Power Plant on-grid and off-grid systems in buildings with a power of 60,500 Wp by going through the stages of calculating the required load according to the conditions in the building, to obtain the required PLTS component capacity. In the long term, there will be an understanding of the use of renewable energy sustainably. The comparison results show that the cost between installing on-grid PLTS and installing off-grid PLTS is actually greater for on-grid PLTS with a cost of Rp. 444,301,500 than for installing off-grid PLTS with a cost of Rp. 332,214,000. However, the on-grid PLTS system offers a better system because it does not require a large area for battery storage, lower maintenance costs and can remain connected to the main network so it is very suitable for industrial needs.

Abstract

The existence of batteries in the substation functions to maintain the stability and reliability of the DC electrical system, where the protection system on the control panel must not go out. Therefore, routine battery maintenance and testing are needed so that the battery can run properly and optimally. Battery testing is a routine agenda that is carried out every 6 months. For daily maintenance, a visual inspection (vision) can be carried out, while monthly maintenance is carried out in the form of a battery equalizing test which is carried out so that the 110V DC battery remains stable and can supply DC to auxiliary equipment when in an emergency. The test results obtained in this study were that the equalizing test on the 110V DC battery that was carried out obtained the battery results in normal conditions. This is explained, when the battery is connected to the load and the voltage per battery cell is measured in floating charging mode showing an average voltage of 1.34 V DC. When the battery is in equalizing charging mode, the voltage capacity on each battery cell can be said to be normal or stable with a total voltage value of 128.2 V DC and a temperature value of 27 ºC. For the measurement results of each battery cell after equalizing charging, the average voltage value per battery cell is 1.35 V DC with a total voltage of 116 V DC. It can be concluded that the equalizing test on the 110V battery unit 1 of the 150 KV Main Substation is fairly normal and the battery is ready when run in discharge mode

Abstract

Air temperature and humidity factors can affect the growth and development of oyster mushroom plants. Ideally, oyster mushroom cultivation in highland areas has a low temperature, ranging from 22-28 ° C and humidity> 70%, if the cultivator wants to develop oyster mushroom cultivation has land / location in the lowlands which tends to have high temperatures, the mushrooms will die easily. In lowland locations the average temperature is 33-37 ° C, so there is a need for a tool that can control and monitor the humidity and temperature of the mushroom cultivation room, so that the cultivation room gets the ideal temperature. In this research, the author makes a monitoring system for air temperature and humidity using a DHT-11 sensor in Internet of Things-based oyster mushroom cultivation in an oyster mushroom cultivation house, if the temperature in the room is detected> 28 ° C, the Raspberry Pi microcontroller will give orders to the relay to turn on the fan and water pump. Fans and water pumps function to increase humidity and reduce temperature. This tool can certainly make it easier for us to monitor and control the temperature in the room, so that the temperature in the room can be maintained, so that oyster mushrooms can grow well and have good quality too.

Abstract

The differential relay is one of the protection components used to detect internal faults in transformers by comparing the incoming and outgoing currents within the protection zone. This study aims to analyze the effect of short-circuit faults on the operation of the differential relay using Electrical Transient Analyzer Program (ETAP) software. The method used is descriptive quantitative with a simulation-based approach using ETAP and binary logistic regression analysis. The results of the binary logistic regression test indicate that fault location and fault type do not significantly affect the relay operation decision, with a significance value of 0.989 and a Nagelkerke R Square of 0.016. These findings are consistent with the fundamental principle of differential relays, which focus on the difference between incoming and outgoing currents, rather than the fault position or fault type.

Abstract

Electricity has become a primary necessity in modern life, and the substation functions as a pivotal hub for its distribution from the source to the customer. This critical infrastructure is equipped with vital equipment such as PMT (Power Breakers), which play a crucial role in ensuring system reliability. The PMT serves dual functions as both a breaker and a connecting switch, handling anomalies or network repairs efficiently. However, PMT operations frequently involve arcs, which have the potential to damage equipment. To mitigate this risk, SF6 insulating gas is employed to effectively extinguish arcs, ensuring the safety and reliability of the electrical network. Routine testing is imperative to ensure the efficacy of SF6 gas, encompassing assessments of purity, dew point, and decomposition products. The present study was conducted over a period of two months at the 150kV Kalibakal Substation. The research method incorporated field observation, a comprehensive review of existing literature, and rigorous SF6 gas testing procedures.The study's findings revealed that the average purity of SF6 gas exceeded 97%, the presence of decomposition products of SO2 was absent, and the dew point was recorded to be less than -5°C. Additionally, the SF6 gas pressure at Bay bumiayu 1 and bumiayu 2 remained within safe limits, exceeding 6.4 bar.A significant decrease in pressure could potentially compromise the functionality of the PMT, as it was observed that the PMT operates optimally at pressures above the nominal value. However, at pressures below the nominal value, the performance of the PMT is compromised, leading to malfunctions in the arc fire extinguisher and potentially causing equipment damage and endangering human safety. The findings indicate that the condition of SF6 gas is stable and safe for substation operations.

Abstract

Cardamom is a high-value spice commodity with significant potential as a raw material for essential oil production; however, its utilization at the village-farmer level remains dominated by the sale of raw materials due to limited postharvest technology. This study aims to experimentally evaluate the performance and Technology Readiness Level (TRL) of DryStilla, an integrated steam distillation and drying system specifically designed for small-scale, village-based cardamom processing. The research employs an engineering-based experimental method through field testing in a real operational environment at the Cardamom Berkarya Farmer Group in Karangkemiri Village. The evaluation focuses on technical performance, operational efficiency, essential oil yield, system stability, and initial economic impacts. The experimental results indicate that DryStilla reduces drying time from 2–3 days to 6–8 hours, increases essential oil yield by more than 50% (approximately 3.0–3.5%), and significantly reduces the loss of volatile compounds compared to conventional methods. The integrated drying and steam distillation system also improves energy efficiency, operational simplicity, and suitability for village-scale production. TRL assessment shows that DryStilla has achieved TRL levels 7–8, indicating that the system has been successfully demonstrated and operates stably in a real operational environment. These findings demonstrate that DryStilla has strong potential as an appropriate postharvest technology to support cardamom downstream processing, enhance product value, and strengthen the economic independence of rural farmers

Abstract

The Effect Of Loading On The Power Capacity Of A 1-Phase 50 Kva Distribution Transformer. The 50 kVA distribution transformer at the SNT04-109 substation plays an important role in distributing electrical energy to customers. However, increasing loads can accelerate the decline in transformer performance and lifespan. This study aims to analyze the effect of loading on transformer power capacity using a descriptive quantitative approach based on load current data from 2019 to 2023. The results show that the average nighttime load current increased from 96 A in 2019 to 131 A in 2023. Based on calculations, the actual power carried has reached 28.9 kVA or 72.2% of the maximum capacity. With an annual load growth trend of around 8.7%, it is estimated that transformers will experience overloading in the coming years. If load management or uprating is not carried out, the risk of damage and decreased operational efficiency will increase. Therefore, routine monitoring and capacity planning are essential to maintain the reliability of electricity distribution.

Abstract

This Study Aims To Analyze The Effect Of Loading On The Life-Time Of A 50 Kv Distribution Transformer at Penyulang LMS01, Tambakreja Village, ULP Cilacap Kota. Distribution transformers are critical components in power systems, and overloading can accelerate performance degradation and reduce their lifespan. The research method involves measuring current, voltage, and load power of a B&D transformer from 2019 to 2023. The analysis reveals that excessive loading, especially during nighttime, reduces the transformer's lifespan by 8 years and 9 months from the standard 20 years, with an error value of 44,25%. The remaining lifespan is estimated at only 11 years and 3 months. This study recommends regular monitoring and limiting loads to below 80% capacity to extend the transformer's operational life.
