Abstract

Alat penukar kalor merupakan alat yang digunakan untuk pertukaran kalor antara dua fluida yang memiliki temperatur berbeda. Jenis alat penukar kalor ang digunakan pada penelitian ini adalah double pipe (pipa ganda). Jenis ini dipilih karena mempunyai desain yang cukup simple dan perhitungan analisis termal yang cukup mudah. Jenis aliran fluida yang digunakan adalah aliran searah (cocurrent flow) dan aliran berlawanan arah (counter flow). Tujuan yang ingin dicapai pada penelitian ini adalah mengetahui karakteristik perpindahan kalor jenis aliran fluida searah (concurrent flow) dan aliran berlawanan arah (counter flow). Metode perhitungan yang digunakan menggunakan perhitungan LMTD (Log Mean Temperatur Difference) yaitu rata rata logaritmik dari perbedaan temperature aliran fluida panas dan aliran fluida dingin. Hail yang diperoleh dari perhitungan LMTD kedua jenis aliran fluida yaitu, aliran searah (concurrent flow) sebesar sebesar 173,056 °K dan untuk aliran berlawanan arah (counter flow) diperoleh nilai sebesar 173,057 °K. Selisih yang diperoleh dari perhitungan LMTD kedua jenis fluida mempunyai nilai yang tidak signifikan, hal ini dikarenakan temperatur masuk dan temperature keluar dari alat penukar kalor mempunyai selisih yang relative kecil, sehingga memengaruhi terhadap perhitungan LMTD. Beban kalor yang diperoleh dari kedua jenis aliran fluida yaitu aliran searah (concurrent) sebesar 11,512. 58 W dan untuk jenis aliran berlawanan arah (counter flow) sebesar 11,512. 59 W.

Abstract

Eggs and quail meat are in great demand by the public because they have high nutritional value and affordable prices. Consumption of eggs and quail in Ciamis Regency continues to increase. increased consumption should be followed by egg and quail production. To meet these needs, it is necessary to manufacture a quail egg incubator (incubator) so that the egg hatching process is relatively easier and more practical with better hatching results. This service aims to provide training for the manufacture of demonstration plots for the heating system of the quail broodstock cage by utilizing the wasted heat from the incubator. In addition, it can also provide training and skills for making quail egg incubators with a capacity of 50 eggs so that hatching eggs is relatively easier and more practical with better hatching results. The service activity was carried out by providing counseling about raising quail eggs, then continued by providing training and skills in making an egg incubator (incubator) then the next stage providing skills in making demonstration plots of the heating system for quail egg brooders by utilizing the wasted heat from the incubator. The results of the service that have been carried out are as follows quail farmers in Sandingtaman Village have skills in making egg incubators (incubators) and making quail egg cages by utilizing wasted heat from the incubator. The results of the activity of one quail egg incubator that can be used by farmers

Abstract

Specifically used to connect plates. A high electric current is applied to the material that is squeezed through the electrodes during the pressing process by the two electrodes. Spot Welding is widely used in the industrial world both large and small scale. In large industries, spot welding has a solid and fixed design, meaning that the method of placement has been determined in a special place and if you want to move it, you have to use heavy equipment. Whereas for small-scale spot welding it is urgently needed for thin plate processing, but the price and shape which are difficult to move certainly require innovation so that the needs of small industries can be fulfilled. In the manufacturing process course in the Mechanical Engineering Study Program, Faculty of Engineering, Galuh University, there is welding material and practice, of course, to achieve maximum learningoutcomes in welding practice, it is necessary to make a portable spot welding equipment. From the discussion above, the authors are interested and inspired to design a portable spot weld machine for the laboratory scale, starting with drawing, planning, sketching or assembling several separate elements into a single unit that is used to describe tools using solidwork applications and the Finite Element Method (FEM) or commonly called Finite Element Analysis (FEA) as an analysis tool. The method used in the design process for portable spot welding machines is made using Solidwork software. The design dimensions of the spot welding machine are 63 cm long, 14 cm wide, 14 cm high. The dimensions of the pedal that has been made are 10 cm long, 38 cm wide and 98 cm high. Electrical specifications require 700-800 watts of power, 220 volts, 5 amperes electric current. The design analysis that has been carried out is divided into stress analysis which has a value of 2,476,233N/m2, while the yield stress of the ASTM A36 material is 250 MPa so that the frame is declared safe. Displacement and strain analysis produces a value of 0 and safety of factor analysis produces a value of 101.
