Abstract

Sajen Village, in Pacet District, Mojokerto, already has a Village-Owned Enterprise (BUMDes) that is primarily involved in the management of livestock and agricultural products because has village treasury land. Farms with cows and goats are administered by cooperatives of farmers. Even though there is always a livestock supervisor on guard, one of the farm locations closest to the village hall uses makeshift lighting and has a low level of security. This is due to the limited electrical energy which is still sourced from the village hall. In addition, human resources in Sajen village also need to improve their soft skills and hard skills to develop the village and keep abreast of current issues. This initiated the idea of building an independent power plant in the livestock area as a useful energy source for village lighting and security. Off-grid system was built in the livestock area and has been successfully utilized to supply energy for the lighting and security sector in the livestock area. Off-grid systems refer to energy sources that are different from those used by the state power utility. Solar power plant also contributes a percentage of clean energy use in village areas and can be a pilot for further development.

Abstract

Electrical system power supplies always require a completely sinusoidal voltage signal. But for a variety of reasons, utilities often struggle to maintain these desired conditions. Deviations of voltage and current waveforms from a sinusoidal form are called harmonic distortions. Harmonic distortions in power networks are increasing due to the widespread use of non-linear loads. In this article we will analysis at a single-tuned passive filter and optimization using a capacitor bank. Load-current analysis determines the efficiency of the filter application by calculating the load bus voltage and total harmonic distortion (THD). To simulate the work, the Electrical Transient Analyzer Program (ETAP) software was used. This system was created specifically for this simulation and does not represent a real system. This model tests the effects of injecting harmonic currents into a power grid through a variable speed drive (VFD). The filter is attenuated with a capacitor bank.

Abstract

Electrical conditions in the operations building and substation of the regional general hospital Dr. Saiful Anwarexperienced a power cut at optimum load, resulting in the power supply being solely obtained from the generator. The aim of the assessment carried out was to delve deeper into power quality, electrical performance, and other supporting equipment to maximize service to patients based on the assessment findings. The assessment stages utilized were the initial assessment stage and the detailed assessment stage. The analysis stages were conducted under steady-state load conditions. The assessment process involved field measurements, observations, and interviews with technical staff at the general hospital Dr. Saiful Anwar. Field measurements utilized Ammeters, Voltmeters, and Harmonic Analyzers to ascertain voltage imbalances, current imbalances, and harmonic content in SDP panels on each floor of the operations building, as well as to evaluate UPS components as backup power and stabilizers for electrical equipment. The results of observations and direct measurements in the field revealed several issues, including a current harmonic content of up to 50% on the 6th floor of the operations building (OK6) and in the Linac room, along with various other findings related to voltage and current imbalances in the secondary substation and certain components. The UPS, alike to the battery and filter capacitor inside, requires replacement. Additionally, regarding the grounding value, which currently stands at 3 Ohms, it is imperative to incorporate a parallel grounding system to bring the value below 1 Ohm to mitigate the risk of leakage current occurrences.

Abstract

Tower 1 at Institut Teknologi Sepuluh Nopember Surabaya is a high-rise building (High Risk Building) in the education and office sectors, experiencing an annual increase in energy consumption. Therefore, regular and thorough energy audits are necessary to save electricity consumption and ensure that usage aligns with the Indonesian Ministry of Energy and Mineral Resources Regulation No. 13 of 2012. An energy audit is a method to calculate the energy consumption level of a building and determine potential energy savings through energy conservation. The Electrical Energy Consumption Intensity (IKE) is used as a parameter to determine whether the building's energy consumption is efficient or wasteful. The initial energy audit of Tower 1 was conducted quantitatively with on-site measurements over one year, covering the building's electrical system and area. The measurements indicated that the IKE of Tower 1 is 50.86 kWh/m²/year. Subsequently, the total installed electrical energy consumption load was calculated, yielding an IKE of 166.15 kWh/m²/year. Based on the initial energy audit results, energy conservation measures were recommended, including upgrading the lighting system with higher lumen lamps and adjusting air conditioning (AC) to the established standards. Implementing these recommendations resulted in an increased IKE of 176.04 kWh/m²/year, which is still considered efficient compared to the ASEAN-USAID standard of 240 kWh/m²/year.
