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

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.

Abstract

Along with the times and advances in science and technology, plastics are increasingly being used by people in various products because of their diverse interests. Many industries make plastic as the main raw material in the production process. Processing of plastic seeds until it became finished products can be done in many ways one of them is injection molding. But there are some obstacles when plastic products are made in large quantities, so they need to improve the quality of products they are produced.One way to improve the quality of products is by optimizing the parameters. Parameter optimization is a technique used in the manufacturing process to produce the best product. This study aims to optimize injection molding parameters such as injection time, injection pressure and holding time to optimize inner snap diameter and netto on pot cream products. Each parameter has 3 levels which are designed using Box-Behnken method. In this research using ANOVA method to analyze experimental data and the optimization of inner snap diameter and netto in injection molding process is done by using response surface method.Based on the results, it is known that the parameters of injection time, and holding time has an influence on the inner snap diameter. While for the netto all parameters have influence such as injection time, injection pressure, and holding time. For optimization, the configuration of injection time parameter is 3.74 seconds, injection pressure is 47%, and holding time is 1.5 seconds which produce 46.11 mm of inner snap diameter and netto 8.7 gram.
