Abstract

The development of the use of renewable energy that is environmentally friendly has been widely carried out, one of which is the use of energy as a turbine drive in the Pico Hydro Power Plant. The main problem in using energy, especially water energy, is the flow of water which can affect the flow of water used to rotate the turbine, so that the voltage on the DC link cannot be kept constant. Therefore, in this paper, we will design and simulate the charging process for a lead acid battery with a DC-DC converter and a Pico Hydro Power Plant as the main source. The type of generator used in the Pico Hydro Power Plant is a DC generator. The output voltage of the DC generator is still fluctuating, so to keep the output voltage constant, a DC-DC converter is needed, namely the ZETA Converter, so that its efficiency will be better when compared to using other types of converters. The ZETA converter with a DC generator as a source will be used for the battery charging process using the Fuzzy Logic Controller so that the output voltage of the ZETA converter can be kept stable or constant. The results obtained in the close loop simulation test are that the output voltage is constant at 14.4 V and the output current is 6.64 A so that it can be used for the battery charging process that will be used for household lighting.

Abstract

The electricity production generated by solar panels is not stable due to variations in the intensity of sunlight caused by fluctuating weather conditions, which results in the battery not being fully charged. To ensure a constant output voltage, a PI control method was developed in this study to regulate the duty cycle of the SEPIC converter from the solar panel. The modeling of the PI controller involved determining the P and I gains using analytical methods to obtain optimal system characteristics. The results showed that during closed-loop system testing with solar panel conditions of 1000W/m2 and a temperature of 25°C, the output voltage reached the set point value of 14 V with a response time of 0.6 s.

Abstract

Air cooler has an evaporative mode that is used to get a cooler temperature output than without using evaporative mode. The evaporative cooling process involves water that is cooled with an ice cube placed in a water tank on the air cooler, where the outside air entering the air cooler will be cooler when exposed to honeycomb that has been submerged in cold water from the water tank so that the air temperature released by the air cooler will be cooler. The process of cooling the air temperature of the air cooler uses an ice cube which when used for a long time, the temperature will start to rise again so that the air coming out of the air cooler will rise again and become less cold than before. The purpose of this research is to create a system to keep the water temperature in the air cooler tank stable so that the temperature of the air released will also be cooler. This research was conducted using simulations with MATLAB software. Based on the simulation data that has been obtained, it is found that the temperature can be stabilized at 25 ℃ by using the fuzzy logic control method. By using the 5x5 fuzzy control method, the temperature can reach 25℃ with a time of 0.389ms while with 7x7 fuzzy the temperature can stabilize at 25℃ with a time of 0.407ms. Based on the results of open loop test, the temperature will continue to decrease in the range of 21 ℃, this is because this test does not use fuzzy logic control so that the temperature can't be stable at 25 ℃.

Abstract

Indonesia ranks as the third largest coffee bean producer globally due to its favorable climate for coffee cultivation and production. The drying process is one of the crucial stages in coffee bean processing as it significantly impacts the bean's quality. This study focuses on optimizing the drying process through the implementation of a sun tracking system mechanism. In essence, a sun tracking system is employed to maximize sunlight exposure by controlling the tray's position to constantly align with the sun's movement. The constructed system comprises both mechanical and electrical components. The control methods utilized in this system involve LQR and PID control. Experimental results will be analyzed to determine which controller yields the best performance.

Abstract

Program pengabdian masyarakat ini dilaksanakan di Desa Wisata Kembangbelor, Kecamatan Pacet, Kabupaten Mojokerto, yang memiliki potensi besar sebagai destinasi wisata unggulan. Permasalahan utama yang dihadapi adalah pengelolaan sampah di area parkir yang mengurangi kenyamanan pengunjung dan citra kebersihan desa. Kegiatan dilakukan dengan pendekatan Participatory Action Research (PAR) melalui edukasi pengelolaan sampah, pemasangan poster edukatif, penyediaan tempat sampah organik dan anorganik, serta pelaksanaan forum group discussion bersama masyarakat dan pengelola wisata. Hasil kegiatan menunjukkan peningkatan kesadaran masyarakat terhadap pengelolaan sampah dan berkurangnya sampah tercampur di area wisata. Keterlibatan aktif masyarakat dalam setiap tahap kegiatan menunjukkan efektivitas pendekatan partisipatif dalam menciptakan perilaku ramah lingkungan. Program ini berkontribusi terhadap penguatan citra Desa Kembangbelor sebagai destinasi wisata yang bersih, edukatif, dan berkelanjutan
