Abstract

Turbin air savonius adalah jenis turbin sumbu vertikal yang mempunyai torsi awal yang tinggi dan dapat berputar pada kecepatan aliran fluida yang rendah, sehingga dapat diterapkan pada perairan di Indonesia. Turbin tersebut dapat digunakan pada aliran air untuk mengubah energi kinetik menjadi energi mekanik. Potensi tersebut akan dapat meningkatkan performa turbin. Penelitian ini akan menggunakan metode simulasi CFD (ComputationalFluid Diagram) dengan software Ansys Fluent dan mengkombinasikan dua sudu berbeda yang merupakan hasil variasi nilai (n) pada persamaan Myring n=1 dan n=2. Turbin yang akan disimulasikan memiliki ukuran tinggi 40 cm dan diameter 40 cm. Selain kecepatan arus yang digunakan sebesar 0,22 m/s. Di depan sisi returning blade, silinder sirkular dipasang sebagai pengganggu dengan variasi diameter 8 cm, 12cm, dan 16 cm yang berfungsi untuk meningkatkan performa turbin. Stagger divariasikan pada sudut 0º, 30?, 60º. Hasil yang diperoleh pada simulasi ini menunjukkan bahwa diameter stagger 16 cm dengan sudut 60? memiliki peningkatan performa tertinggi, yakni sebesar 19,9007%. Sedangkan variasi diameter stagger 16 cm dengan sudut 0? menurun sebesar 30,1087% dari turbin air savonius tanpa stagger.

Abstract

Energy is a need that must be met in human life, if the population increases, the need for energywill also increase. A technology is needed to support human energy needs. Therefore, low temperature heatutilization is carried out using the Organic Rankine Cycle as an energy take off from a grid-scale thermalenergy storage in the form of sand media where the heat stored is heat wasted from the heat pump. After theprocess simulation is carried out, the best and feasible fluid to run the system from an ammonia heat pumpis N-Pentane with an efficiency of 7.074%. The storage medium is silica sand. The heat exchanger design onthe tube has an outer diameter of 60.3 mm for the ORC and 42.2 mm for the heat pump with an inner diameterof 54.8 mm for the ORC tube and 32.5 mm for the heat pump. The length of the heat exchanger design pipeis 165,57 m for the ORC and 479,23 m for the heat pump.

Abstract

Indonesia has a lot of livelihoods, especially in industry. Because the Indonesian people are very numerous, the production each year will increase, therefore every producer must be able to overcome every need that consumers want. The manufacturing field is most needed in every industry because every product manufacture must not be separated from the manufacturing process. In a worksheet there must be a hand work tool to facilitate or tidy up a final process. In this case the viscera function as a tool for clamping workpieces is very important. Ragum is a clamping device to clamp the workpiece that will be carried out by the milling process. With the vise, the workpiece can be tightly clamped so as to facilitate the processing process and the results of a process will be maximized. In this Final Project, a maximum stress strength analysis will be carried out on one of the Hydraulic Rigs with the aim that the Raft can be more efficient and operate optimally. The study conducted on this hydraulic formula is expected to be able to overcome problems that often occur in the manufacturing process in the field of production. So that the operator knows more about the work of the hydraulic vise and can operate optimally, and the production work is not hampered due to damage to the vise. In the end, the hydraulic vise will be able to be used longer than the vise that is used carelessly and quickly damaged.

Abstract

Loudspeaker Manufacturing Company is one of the companies engaged in the manufacture of loudspeakers that make components and assemblies for loudspeakers. One part of the loudspeaker is the front plate with tool number 03TP038 which is produced with a press system through two separate procedures and is carried out with two separate tools and work stations. This causes the production process to be less efficient. Press tool design and analysis using CAD / CAE software is an effort made to optimize the production process by designing the press tool into a progressive tool. As well as the strength analysis in the design is used as a determination of feasibility, as well as improvements to the press tool. The results of the study that the Front Plate 3TP038 Press Tool design can be made into a progressive tool by performing the required calculations.

Abstract

One of the uses of steel is as a basic material for making helical gear. Helical gear is made of medium carbon steel S45C which is carbon steel for the use of machine structure. Sometimes in the production process of helical gear has a hardness values that are not in accordance with the standards of hardness that have been determined by the customer. One way to improve the nature of hardness is the hardening process. The hardening process can be done by considering the factors that affected the hardness of a material, such as heating temperature, holding time, cooling medium, and coolant media temperature. In this research, the method of analysis used is Taguchi with signal to noise ratio (RSN) nominal the best to determine the effect of factors and determine the optimal parameter combination in order for knowing the appropriate of hardness value. From the results of research, it is found the factors that influence the hardness of S45C steel in the hardening process of helical gear are the temperature of cooling medium. As for the optimum parameter combination is heating temperature 740oC, holding time 20 minutes, oil cooling medium and coolant temperature 35oC.

Abstract

One of the supporting factors in making noodles is the milling machine. The most modern grinding machine is a motorized noodle grinding machine. But the working process is not optimal because the process of piping and cutting the dough goes apart. Therefore, the automatic noodle grinder dough grinding press press machine (MRPCOPAM) was made. MRPCOPAM has an automatic work process, where the flattened mixture will run directly into the cutting roll. The motor used is a single phase AC motor with a rotating speed of 2800 rpm, which is then reduced to 35 rpm with the help of a 1:80 gear box. The piping roll used is Ø25 mm and the cutting roll is Ø17 mm. The main gear pitch pitch is 18.75. Rear gears for the piping roll have a pitch of 27mm. Rear gears for cutting roll pitch 15mm in diameter.
