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

The increasing demand for sustainable energy sources has encouraged the application of renewable technologies in rural infrastructure, particularly in public lighting systems. This study focuses on the implementation of solar cell and photocell-based street lighting in Gaprang Village, Blitar Regency, as a solution to reduce dependency on conventional electricity and to enhance energy efficiency. The system utilizes photovoltaic modules as the primary energy source to convert solar radiation into electrical power, which is stored in batteries and subsequently used to supply street lamps during nighttime. In addition, the integration of photocell sensors enables automatic control of the lighting system by detecting environmental illumination levels, ensuring that the lamps operate only when required. The design and installation process involved site surveying, load estimation, solar panel configuration, and the application of photocell-based automation. The results demonstrated that the system provided reliable illumination for rural roads, significantly lowering operational costs and minimizing environmental impact compared to traditional grid-powered lighting. Furthermore, the use of photocells improved energy management by preventing unnecessary power consumption during daylight. The activity will take place in August 2025, with a focus on installation in Gaprang Village. The results of the activity include community understanding of the benefits and maintenance of street lights, as well as the implementation of solar cell-based technology. The conclusion states that this project can provide a positive and sustainable impact, empowering communities and creating efficient infrastructure that aligns with renewable energy initiatives.
