The current energy crisis requires us to look for sustainable solutions to meet energy needs. The Indonesian government has targeted renewable energy use of 23% by 2025, especially in remote areas. One solution to overcome this challenge is energy storage technology. Energy storage using floating technology is an innovative solution that is being developed. In this research, we analyze the design of a floating energy wheel with a capacity of 110 kW as an alternative source of electrical energy. Wheel energy is produced from a combination of buoyancy energy and energy originating from the weight of water which is produced by the difference in fluid density in the water and air environments. The research results show that this floating energy wheel can produce a torque of 7710,62 Nm and a power of 113,83 kW, showing great potential in renewable energy storage applications. Wheel-based floating energy generation technology has the potential to be an innovative solution in renewable energy storage. Further research needs to be carried out on a larger scale and field tests to validate the potential and efficiency of this technology in the real world</em></p> Yulikastomo Dan Mugisidi Fadhlurrahman Zaki Oktarina Heriyani Copyright (c) 2024 Yulikastomo - https://creativecommons.org/licenses/by/4.0 2024-02-19 2024-02-19 9 1 1 12 10.21070/r.e.m.v9i1.1690 https://rem.umsida.ac.id/index.php/rem/article/view/1688 <p><em>The need for energy every year both in the domestic and global increases. Indonesia's energy needs are predicted to increase by 5% each year. Indonesia has renewable energy potential from solar, hydropower, wind, and geothermal sources. The potential of new renewable energy amounted to 442 GW. Of the 442 GW, the greatest potential is owned by 207 GW of solar energy. The high potential of solar energy in Indonesia is because Indonesia is located in the tropics which experiences sunshine time of approximately 6-8 hours per day and the sun continues to shine throughout the year. However, the length of irradiation also has an impact on increasing the temperature of solar panels. The higher the temperature of the solar panel, the output power will decrease and the life of the solar panel is reduced. The use of passive cooling from reference has a lower efficiency increase than active cooling. However, its installation requires lower costs, minimal maintenance, and no additional power requirements. This research will use 20WP monocrystalline solar panels with three cooling variations, namely: 1) with the addition of a thin aluminum plate and Vortex generator 2) By giving a tub of water under the panel 3) the Addition of aluminum fin.&nbsp; The three variations are compared with solar panels without cooling.</em> <em>The results on the first day showed a decrease in temperature of 2.30C with aluminum fin and an increase in power of 6.97% when using a water container. On the second day, a temperature decrease of 2.90C and a power increase of 5.81% when using aluminum fin coolers were recorded.</em></p> Muhammad Trifiananto Intan Hardiatama Aris Zainul Muttaqin Mochamad Edoward Ramadhan Gaguk Jatisukamto Muhammad Dimyati Nashrullah Adib Al Wafi Copyright (c) 2024 Muhammad Trifiananto, Intan Hardiatama, Aris Zainul Muttaqin, Mochamad Edoward Ramadhan, Gaguk Jatisukamto, Muhammad Dimyati Nashrullah, Adib Al Wafi https://creativecommons.org/licenses/by/4.0 2024-03-05 2024-03-05 9 1 13 20 10.21070/r.e.m.v9i1.1688 https://rem.umsida.ac.id/index.php/rem/article/view/1689 <p><em>Dengan bertambahnya e-commerce maka bertambahnya juga kebutuhan warehouse sedangkan rate produktifitas warehouse selalu berubah yang mengkabitkan kebutuhan jenis rack. Olehkarena itu, diperlukannya jenis rack yang dapat diajutable sehingga penggunaan rack dapat diseuaikan dengan jenis rate produktifitas. Tujuan dari penelitian ini adalah untuk menyajikan rak yang dapat disesuaikan untuk gudang e-commerce dengan merancang dan mensimulasikan menggunakan perangkat lunak. Makalah ini melibatkan evaluasi berbagai metode dan desain rak. Proses perancangan desain menggunakan perangkat lunak Autodesk Inventor 2023 dan simulasi analisis menggunakan metode elemen tak hingga yang menganalisis von mises stress untuk horizontal dan vertical frame, displacement nilai factor kemanan. Kami mendapatkan nilai untuk von misses stress untuk frame rack sebesar 9990,69 MPa, sedangkan untuk nilai displacement 119,229 mm, dan untuk nilai factor kemanan adalah 0,00275.

Suatu desain mikrohidro membutuhkan dua hal, debit air serta ketinggian jatuh (head) berguna untuk menciptakan daya yang bisa digunakan. Pada riset ini memakai turbin air dengan jenis Pelton, diseleksi turbin itu sebab sesuai diaplikasikan pada head yang cukup tinggi. Saat sebelum diaplikasikan butuh terdapatnya pengetesan dengan prototipe agar mengenali seberapa besar jumlah putaran yang diperoleh. Tujuan dari riset itu digunakan untuk mengenali pengaruh variasi diameter nozzle dan tekanan air terhadap daya dan efesiensi turbin. Turbin yang diuji mempunyai nilai efisiensi sebesar 15,7%. Dan didapatkan bahwa semakin kecil diameter nosel maka&nbsp; tekanan air pada turbin akan semakin meningkat dan daya pada turbin akan semakin besar. Daya maksimum turbin&nbsp; dicapai pada 7,02 watt.</p> Arasy Fahruddin Vicky Iswidiyanto Iswanto Iswanto Copyright (c) 2024 Arasy Fahruddin, Vicky Iswidiyanto, Iswanto Iswanto https://creativecommons.org/licenses/by/4.0 2024-03-10 2024-03-10 9 1 29 34 10.21070/r.e.m.v9i1.1692 https://rem.umsida.ac.id/index.php/rem/article/view/1694 <p><em>Salah satu potensi energi terbarukan yang semakin populer penggunaanya adalah modul surya.
