Abstract

A room can be categorised as comfortable or not depending on the temperature and humidity of the air in the room. In order for the room temperature to be maintained, an Air Conditioner (AC) is needed. In the AC there is refrigerant as the most important component that functions to provide cool and cold effects in the room. However, refrigerant leakage in AC is one of the causes of greenhouse emissions that have an impact on climate change. In order to reduce the emissions caused by AC usage, many researchers are utilising Peltier as a device designed to replace the AC cooling system. In order for TEC to work optimally when cooling the air in the room, it is necessary to design a combination system of Portable Air Conditioner (AC) cooling using TEC and Arduino Uno-based water cooler. The working principle of designing a portable Air Conditioner cooling combination system using TEC and water cooler requires a temperature set point value in the water cooler system, where the Arduino is given a set point temperature range on the heatsink. The temperature on the heatsink affects the pump speed. if the higher the temperature on the heatsink read by the DS18B20 temperature sensor, the pump will work quickly to cool the heatsink side. The temperature on the heatsink, pump speed, and the height of the water cooler in the tub are displayed on the LCD. Before assembling and arranging the components that will be used in the portable Air Conditioner cooling combination system using TEC and water cooler, the design flow of the working principle and tool design of the portable Air Conditioner cooling combination system is needed. After the components are assembled and arranged, the test results are obtained with the conclusion that the TEC with the water cooler method is better at cooling a room measuring 1x1 metre than the water cooler method.

Abstract

The sunlight absorption is the main technical factor of solar power plants performance because it affects to the amount of solar energy conversion. In order to optimize this absorption, the position of solar panel should be adapted to the direction of sunlight so it can improve the economic factor of solar power plants utilization. Furthermore, in this research, we have designed and tested three serial connection solar panels with single solar tracker (SST) to optimize the absorption of sunlight and its conversion to electricity, where the electrical current from panel with SST (1.41 – 2.52 A) is higher than panel without SST (0.89 – 1.59 A). Another parameter, namely electrical power of solar power plants, is proportional to electrical current and also higher than without SST (65.2 – 102.4 W), so the stored electrical energy in battery can be also increased. The utilization of Arduino Mega 2560, driver motor BTS7960, and linear actuator can optimize the solar panel absorption and finally this control circuit addition can increase the solar energy conversion to electricity. Besides that, this control circuit will reset the position of solar panel at 6.30 pm to the starting position. It means the solar energy conversion can be maximized by using SST and this advantage can increase the efficiency and support the transition to renewable energy.

Abstract

This research examines how load variations affect the performance of a pico-hydro power system, specifically focusing on voltage, current, frequency, and generator speed. Experiments were carried out through direct measurement under different load conditions. The findings reveal that as the load increases, the output voltage decreases due to higher circuit resistance, while the output current rises significantly. The generator frequency remains relatively stable under light loads but starts to fluctuate near full capacity, indicating the need for improved regulation. Similarly, the generator’s rotational speed declines with higher loads, signaling a performance limit. These results highlight the critical relationship between load changes and system performance, providing valuable insights to enhance the efficiency and stability of pico-hydro systems, especially for renewable energy applications in remote areas.

Abstract

Maize drying is a crucial procedure in the agricultural and food industries, aimed at decreasing the moisture content of maize kernels to prolong their shelf life, inhibit microbial growth and maintain their quality. Two common methods for drying corn include natural techniques, which involve drying the maize in the sun, and artificial techniques, where specialized equipment such as hot air dryers, drum dryers and microwaves are employed. The author constructed a corn dryer utilizing Arduino. This device employs heat elements and fans to expedite the corn drying process. The tool can significantly quicken the corn drying process. The author utilises a DHT22 sensor to gauge temperature and humidity levels of the corn. The device is capable of generating temperatures ranging from 20?C to 90?C, thanks to the assistance of the DHT22 sensor during the drying process.

Abstract

Kegiatan pengabdian kepada masyarakat dengan judul “Pemanfaatan Pembangkit Listrik Tenaga Pico Hydro (PLTPH) Turbin Cross-Flow pada Perkebunan Masyarakat Bukit Aur” ini bertujuan untuk mengadakan suplai listrik bagi petani durian yang berkebun di Bukit Aur. Dimana perkebunan durian ini dapat menjanjikan kontribusi signifikan terhadap ekonomi lokal. Namun, tantangan yang dihadapi berupa akses terhadap listrik yang terbatas. Dengan infrastruktur listrik yang terbatas menyebabkan sebagian besar masyarakat bergantung pada sumber energi konvensional yang mahal dan merugikan lingkungan. Sumber energi konvensional yang digunakan oleh masyaraka ialah penggunaan senter atau lampu lantera sebagai alat penerang ketika musim panen. Penggunaan sumber energi konvensional ini membutuhkan biaya yang mahal dan dapat merugikan lingkungan jika tidak bijak dalam penggunaannya. Oleh sebab itu, perlu adanya aliran listrij di Bukit Aur. Pada kegiatan pengabdian kepada masyarakat ini, pembangkit listrik yang dihasilkan oleh tenaga pico hydro ialah sebesar 300 Watt, sehingga masyarakat dapat memanfaatkan listrik yang tersedia untuk menghidupkan lampu, men-charge baterai handphone, dan menghidupkan alat elektronik yang dayanya dibawah 300 Watt atau total untuk keseluran daya pada alat elektronik yang hidup di bawah 300 Watt. Dalam kegiatan pengabdian ini, dengan daya yang dihasilkan oleh pembangkit dapat menghidupkan 3 buah lampu dengan daya 39 Watt dan sekaligus dapat men-charge baterai handphone sebanyak 5 buah.
