Abstract

Archive management is very important for an institution. Archive management at Panca Marga University has not been done computerized. Manual management raises several problems, including slow search, need for extensive mail storage and rather slow distribution. These problems can be solved by building an information system for filing and distributing mail. System development use the waterfall method. In this study, a system can be built to be able to manage incoming letters, outgoing letters, decision letters, letter dispositions along with the distribution of the letters. Based on the results of black box testing, the system that was built was running according to its functionality.

Abstract

This research aims to design and develop an advanced monitoring system for solar cells, incorporating solar tracking technology and equipped with an energy storage protection system. In Indonesia, the substantial potential of solar energy remains underutilized, despite the country's advantageous equatorial location, which provides a solar radiation intensity averaging 4.5 kWh/m² per day. The proposed system in this study seeks to maximize solar energy capture by employing a tracking mechanism that aligns the solar cells with the direction of sunlight throughout the day. Additionally, the system is designed with an integrated protection feature to prevent battery overuse, thereby extending the battery's lifespan and ensuring efficient energy storage. The research utilizes an Arduino Uno microcontroller, Light Dependent Resistor (LDR) sensors, and an INA219 sensor module as the primary components for accurate measurement and real-time monitoring. The system's effectiveness is evaluated based on its ability to optimize solar energy reception and maintain the longevity and efficiency of the energy storage system. Experimental results demonstrate that the developed system significantly improves the efficiency of solar energy capture by the solar cells and provides robust protection for the energy storage mechanism. This study contributes to the field of renewable energy by offering a practical solution for enhancing solar energy utilization in regions with high solar irradiance, thus promoting sustainable energy practices and reducing dependence on non-renewable energy sources.

Abstract

This study aims to evaluate the impact of RLC loading on the power stability and power quality in Wind Power Plant (PLTB) systems. The RLC is applied to stabilize the power generated by the PLTB system, which tends to fluctuate due to wind speed variability. The testing was conducted by measuring the output power of the PLTB system loaded with various RLC configurations. The results show that RLC loading can enhance the apparent power stability and efficiency of the PLTB system. The resistive load (R) yielded the best performance, improving the power factor to 0.95 and maintaining relatively stable output voltage. Meanwhile, the LC loads exhibited lower efficiency with a reduced power factor, but still played a role in balancing reactive power. The reduction in reactive power for inductive and capacitive loads indicates that RLC loading can help reduce power waste and improve power quality. This research makes a significant contribution to the development of more efficient and stable PLTB systems and more reliable renewable energy-based power plants, particularly in managing power stability in the face of fluctuations caused by wind variability.
