Abstract

Solar energy is one type of energy utilized, especially for solar panels. Solar panels can convert solar energy into electrical energy. Solar panels, as an alternative source of electrical energy, can be utilized by people who need electrical energy. This research aims to determine the output power produced by solar panels that have not been cleaned and have been cleaned using an automatic solar panel cleaning tool from the difference in motor rotation variations, namely 11 rpm, 27 rpm, and 330 rpm. This research shows that the output power of solar panels that have yet to be cleaned on the first day produces a power of 56.3. In contrast, the output power of solar panels that have been cleaned produces a power of 103.1, and on the second day, the output power produced by solar panels that have not been cleaned. Cleaned was 71.3, and the power of solar panels that had been cleaned produced a power of 97.1. Then, on the third day, the power produced by solar panels that had not been cleaned was 65.5, and the power of solar panels that had been cleaned produced power of 78,6.

Abstract

Clean water is a vital resource that is increasingly difficult to obtain in many regions of the world, including Indonesia, which faces significant challenges in providing clean water. Passive solar desalination is an efficient alternative method to convert seawater into fresh water by utilizing solar energy. This study aims to analyze the effect of varying cover collector heights on distillate productivity in passive solar desalination, using charcoal as an energy-absorbing material. The varied cover collector heights used were 30 cm, 45 cm, and 55 cm. The results of the study show that the smaller the distance between the seawater surface and the cover collector, the higher the distillate productivity. Basin 1 (30 cm) produced the highest distillate (120 ml), followed by Basin 2 (45 cm) with 94 ml, and Basin 3 (55 cm) with 60 ml. This indicates that a smaller gap between the cover collector and the seawater surface increases the evaporation and condensation rates, contributing to higher distillate productivity.

Abstract

In the development of fisheries, especially in tilapia cultivation, promising prospects have emerged with high market demand. However, fish farming still tends to use conventional methods that pay little attention to water quality. This deficiency can cause serious problems for fish health and quality, potentially detrimental to cultivation activities. To optimize fish growth, pH and dissolved oxygen control are necessary. This study created a microcontroller-based automation system to control pH (5-8.5) and dissolved oxygen (> 5 mg/L) in tilapia ponds. Field testing showed that the pH and dissolved oxygen sensors have low error rates of 5.07% and 4.80%, respectively. Laboratory testing showed that the system worked successfully with relative error percentage values of pH and DO testing of 5.71% and 20% of the setpoint.

Abstract

Clean water needed by the entire community is not evenly distributed across various regions in NTT, especially in Enoraen Village, East Amarasi District, Kupang Regency, which is a coastal area. Clean water can be provided in this area through solar thermal desalination. This community service aims to improve the congregation's ability to recognize clean water that is suitable for drinking, as well as to train the congregation to use and maintain desalination equipment to produce clean water. The methods used are lectures and training, as well as periodic guidance. This community service activity consists of education related to clean water and drinking water, training in the use and maintenance of desalination equipment, and assistance for approximately 6 months. The results of the activity showed an increase in the congregation's knowledge in recognizing the quality of clean water suitable for drinking. In addition, the congregation was able to use the desalination equipment, as demonstrated by an increase in the amount of water produced by the equipment after 7 days of use. Assistance in the use of solar thermal desalination equipment is still being provided, particularly to assess the congregation's ability to maintain the desalination equipment so that its use can help in the provision of clean water in the congregation.
