Pendingin ruang muat kapal ikan merupakan sebuah ruangan yang dirancang khusus dengan kondisi suhu tertentu yang mempunyai fungsi utama untuk mempertahankan mutu ikan hasil tangkapan nelayan dengan cara membekukan ikan hasil tangkapan dan menyimpan ikan yang telah dibekukan selain itu bertujuan untuk menghambat berkembangnya bakteri pada ikan sehingga dapat menjaga kesegarannya dan berkualitas. Perencanaan sistem pendingin box / Palka Kapal Ikan menggunakan Tenaga Surya melalui Panel Surya. Pada penelitian sebelumnya, belum dilakukan perancangan tata letak komponen-komponen Panel Surya dan belum dilakukan perancangan instalasi kelistrikan Panel Surya pada kapal ikan. Oleh karena itu perlu diadakannya Penelitian mengenai Perancangan Tata Letak Mesin Pendingin Dan Instalasi Panel Surya Sebagai Supply Daya Sistem Pendingin Ruang Muat KM. JAYA PUTRA. Manfaat pada penelitian yang akan dilakukan yaitu dapat menghasilkan perancangan tata letak komponen-komponen Panel Surya serta merancangan instalasi kelistrikan pada panel surya yang terpasang pada KM. JAYA PUTRA. Selain itu pihak pemilik kapal dapat mengaplikasikan hasil dari penelitian tersebut. Dengan studi kasus tersebut, perlu dilakukan perancangan menggunakan software AutoCAD sebagai desain 2 dimensi, kemudian diterapkan desain 3 dimensi menggunakan software Rhinoceros agar dapat memberikan gambaran visual secara nyata pada penelitian tata letak yang akan dilakukan. Hasil yang diharapkan dari penelitian ini yaitu mengetahui hasil pembuatan tata letak komponen serta instalasi instalasi kelistrikan Panel Surya. Performance yang dihasilkan dari daya kelistrikan Panel surya ini selain sebagai tenaga penggerak sistem pendingin Palka Ikan, juga mampu menghasilkan komoditi berupa tangkapan ikan dengan kondisinya tetap dalam keadaan segar sehingga membuat harga ikan bernilai tinggi dan memberikan metode alternatif terhadap penghematan eneergi bahan bakar.

“…The thrust on the nozzle was found to be greater than that of the other types of impulses. Moreover, the position of the falling water was found to affect the efficiency of the mill [23][24][25][26][27][28][29][30][31][32]. Efficiency is an important determiner of the effectiveness of waterwheel performance and the development of waterwheel research [33].…”

Water flow in irrigation is a means of obtaining electric power, which is commonly called microhydro. The waterwheel is the main component of the microhydro energy conversion process. The amount of energy converted by a waterwheel depends on the shape of its model, blade shape and the location of the installer. This study aimed to identify the characteristics of optimally efficient waterwheels. In addition to the energy of the place (i.e., the head), the influence of the weight of the water flowing into the blades of the waterwheel must be considered. This study also aimed to determine the effectiveness of mill performance by comparing waterways that use nozzles with those that use open canals. An experimental method was used to design a waterwheel system by testing the efficiency ratio between the nozzle line and the open canal. This test used the following variable water discharge rates: 12 m 3 /hr, 14 m 3 /hr, 16 m 3 /hr, 18 m 3 /hr and 20 m 3 /hr. Using the nozzle line with the largest discharge rate of 20 m 3 /hr, an rpm of 192.7 is produced with a torque of 0.7 Nm. The waterwheel produced 14.13 Watts, with an efficiency of 64.75%. A line that used an open channel at the highest discharge rate of 20 m 3 /hr produced 61.7 rpm with 0.7 Nm of torque and 4.52 Watts with an efficiency of 20.71%. The speed of water flow in the nozzle line was faster than in the open canal path, causing the tangential force on the waterwheel to be greater than on the open canal path. Based on these results, it was concluded that the path was the most efficient when using a nozzle.

This research discusses developing an Euler turbine-based hybrid mesh turbomachinery. Within the framework of mechanical engineering science, turbomachinery classification and a novel method for mesh turbomachinery design were considered. In such a turbomachine, large blades are replaced by a set of smaller blades, which are interconnected to form flow channels in a mesh structure. Previous studies (and reasoning within the framework of inductive and deductive logic) showed that the jet mesh control system allows for operation with several flows simultaneously and provides a pulsed flow regime in flow channels. This provides new opportunities for expanding the control range and reducing the thermal load on the turbomachine blades. The novel method for performance evaluation was confirmed by the calculation: the possibility of implementing pulsed cooling of blades periodically washed by a hot working gas flow (at a temperature of 1000°C) and a cold gas flow (at a temperature of 20°C) was shown. The temperature of the blade walls remained 490–525°C. New results of ongoing research are focused on creating multi-mode turbomachinery that operates in complicated conditions, e.g., in offshore gas fields. Gas energy is lost and dissipated in the throttle at the mouth of each high-pressure well. Within the framework of ongoing research, the environmentally friendly net reservoir energy of high-pressure well gas should be rationally used for operating a booster compressor station. Here, the energy consumption from an external power source can be reduced by 50%, according to preliminary estimates. Doi: 10.28991/CEJ-2022-08-11-017 Full Text: PDF
