Abstract

A solar panel will be exposed to sunlight when in use, which causes its temperature to increase. The performance of power production will be impacted if the solar panel's temperature conditions are too hot. High-temperature solar panels can reduce the amount of electrical energy generated. To prevent the temperature of the solar panels from rising too much, a cooling system is required. The proposed solution of this research is a cooling system for solar panels that makes use of heat transfer through water. The solar panels tested in this study have a tilt angle of 20 degrees. The cooling device has dimensions of 400 mm length, 278 mm width, and 20 mm height, with a wavy-type vortex generator positioned in the cooling device mounted on the underside of the solar panel. As a result of the heat flux applied to the top surface of the solar panel, it causes an increase in temperature. The resulting voltage and electric current are reduced. Computational simulations were carried out to determine the performance of the type of vortex generator used. At a cooling water flow rate of 200–600 ml/min, heat transfer with a vortex generator type B works optimally.

Abstract

Based on its geographical location, Indonesia has the potential to use solar energy as a future energy source, considering that Indonesia is located on the equator, which means that Indonesia is always exposed to the sun throughout the year. One of the obstacles in the application of solar power plants is the low efficiency of solar panels and constraints in their storage so that they can be used at night. Seeing the effectiveness of a solar panel working at a temperature of approximately 25˚ C, the solar panel requires cooling by flowing water on the bottom surface to be more efficient. In this study, a solar panel cooling system was made by providing variations in the flow direction of the water medium used. So that it will be known the effect of the cooling system that has been made, starting with the design and installation scheme until testing is carried out to obtain the required variable data. The results obtained in this study were tested for 40 minutes with a time span of every 2 minutes, the temperature of the fluid used in the cooling system was stable, the temperature test increased. In the solar control test, the electricity produced always decreases, in the volt meter test the voltage produced has decreased and the electric current has decreased significantly, the temperature of the solar panel has increased quite high. Therefore, the results of using a device in the form of a solar panel cooling system can be concluded that it is able to slightly reduce the heat on the solar panel but still requires further study.

Abstract

Pada saat ini UAV (Unmanned Aerial Vehicle) sedang mengalami perkembangan yang begitu pesat di dalam maupun luar negeri, terdapat berbagai macam jenis UAV, namun pada artikel ini penulis membahas UAV untuk misi trainer bagi para pengguna pemula, karena untuk keperluan misi trainer maka analisis kestabilan statik perlu dilakukan agar ketika UAV saat sedang terbang kemudian mendapat gangguan luar berupa angin dan sebagainya, maka UAV tersebut dapat kembali ke posisi kesetimbangan awal setelah gangguan tersebut hilang, sehingga meringankan beban pilot untuk mengandalikan kemudi melalui remote control, pada penelitian ini menggunakan metode reverse engineering yaitu pemodelan ulang UAV meniru Cessna 172 yang sudah ada untuk dimodelkan pada perangkat lunak XFLR5 kemudian dilakukan analisis kestabilan statik, didapatkan hasil grafik sebesar -0,0157 pada matra longitudinal, -0,001 pada matra lateral dan 0,0017 pada matra directional, sedangkan jika dibandingkan dengan menerapkan konsep sayap morphing yaitu jenis sayap yang elastis pada bagian trailing edgenya, diperoleh hasil yang sangat signifikan pada matra longitudinal yaitu sebesar -0,0136 sedangkan pada matra lateral dan directional cenderung saling berhimpit, perbedaan yang sangat signifikan yang terjadi pada matra longitudinal tersebut dipengaruhi berat UAV dengan konsep sayap morphing yang memiliki massa yang lebih berat 422 gram sehingga mempengaruhi posisi center of gravity yang akan bergeser kebelang sebesar 3,4 mm, sehingga sehingga dapat mempengaruhi kestabilan UAV tersebut pada matra longitudinal, dengan hasil tersebut maka dapat disimpulkan bahwa UAV tanpa menggunakan konsep sayap morphing lebih stabil statik setelah dilakukan analisis pada perangkat lunak Xflr5.

Abstract

Aluminum alloy 7075 series is one that is widely used in the aviation industry. More than 73% of aircraft components are aluminum alloy 7075 series because the properties of this aluminum can still be improved by giving it a treatment. The purpose of this study was to determine the effect of differences in nickel coating types on 7075-T6 aluminum plates on the level of hardness.aluminum plates with a length of 2 cm and a width of 2 cm as many as each variation of 4 specimens. temperature variations of 30 °C, 35 °C, 40 °C, 45 °C and time of 5, 10, 15, 20 minutes. The hardness value is obtained using a brinell test device, using a diamond pyramid indenter used for vickers hardness tests. The test object is pressed for 5 seconds with a load of 31.25 kgf and a magnification of 5 times. Hardness testing is carried out at 1 point of the surface of the specimen. Based on the results of research and calculations and discussions about the effect of temperature variations on the strength of mechanics by the electroplating method, it is known that the difference in time and temperature variations on the hardness of aluminum 7075-T6 shows an influence on the value of significant hardness. And the optimal variation value was obtained, namely the highest hardness value at a temperature of 45 ° C at a time of 5 minutes, namely 483.63 kgf / mm² and the lowest average hardness value at a temperature of 30 ° C at a 15-minute immersion time of 292.33 kgf / mm².

Abstract

The simple simulation tool of the heat exchanger has a limitation, that is, when the heat transfer process cannot be analyzed directly, and the flow motion cannot be observed. Therefore it can be solved by the CFD method. The purpose of this study is to provide observable visual images. In this simulation, it uses a tube given a vortex generator with delta variations adding angles, each of which is given a constant inlet velocity, inlet temperature, and heatflux input values. Each angle is given a value of 200, 400, 600. This study aims to obtain a vortex generator with the best angular variation. From the research that has been carried out, it shows that the addition of delta provides a difference in the results of each specimen tested, the addition of a delta winglet with the addition of an angle of 400 is produced to have the best heat transfer coefficient, it is shown at a low temperature difference (ΔT). Analysis of the results of a low temperature difference (ΔT) means that the specimen performed good heat transfer performance.

Abstract

The application of solar power plant technology as a backup power source at Hidayatullah Islamic Boarding School, Yogyakarta, aims to address the challenges caused by disrupted electricity supply. This Islamic boarding school has a strategic location due to its close access to the city center of Yogyakarta. The school relies on electricity for its educational and worship activities. A study was conducted to assess the potential of solar energy, geographical conditions, and the readiness of Hidayatullah Islamic Boarding School to adopt renewable energy technology. After the assessment, structured implementation activities, such as awareness socialization, training, and direct assistance, were carried out to ensure the management of the solar power system by the school administration. The results of the Community Service program showed that a solar power system had successfully been implemented to address disruptions during power outages, thereby improving worship and educational activities. This program encourages partner involvement and environmental awareness among the school management and students. Recommendations for ensuring the program’s sustainability include training, routine performance evaluations, and potential partnerships with government and private organizations to promote the use of renewable energy. This successful program is expected to serve as a model for other educational institutions seeking to implement renewable energy technology.
