Abstract

Hydraulic press tools are usually used in work in the pressing field. The compaction process is a process of forming a powder into a component by using a certain mold. During the compaction process, the metal powder is placed in the mold, then pressure is placed on the mold so that the powder in the mold will be formed following the shape of the mold cavity. The compaction process is carried out by the method of one action compaction pressure and two action compaction pressure method. In the one-action pressing process, the upper cylindrical shaft moves downward pressing the workpiece and for the two-action pressing process, the upper and lower cylindrical shafts move in opposite directions simultaneously pressing the workpiece from the two upper and lower sides. Therefore, in this final project a two-way hydraulic system press is designed which is expected to help the needs of the metal powder compaction process. This two-way hydraulic system press is designed using a bottle jack with a capacity of 10 tons with a large enough capacity. In the research method, the authors collect data, conceptualize, design, make components, assembly, testing and report generation. The results of trials that have been carried out with a two-way hydraulic system press are able to produce the highest pressure of 4000 PSI. These results have not reached the minimum pressure for compacting aluminum powder, which is 5000 PSI.

Abstract

Pineapple fruit is only used for its flesh to be eaten and used for various other forms of food processing. Pineapple skin is thrown away without being used. Traders sell pineapples with the number of pineapples being around 100-120 grains/day. One pineapple produces 0.35 kg of pineapple skin waste, so the pineapple skin waste produced can reach an average of 30-45 kg/day. Pineapple skin waste accumulates and becomes a problem for environmental hygiene. The purpose of this research is to make and build a manual pineapple peel press machine to obtain pineapple peel juice as a raw material for liquid fertilizer. Pineapple skin pulp can be used as animal feed. The stages in the manufacture of this press start from problem identification (field survey, literature study), data collection, design, tool making, assembly, testing, maintenance, conclusion. The capacity of the tool is able to press a maximum of 5 kg of pineapple skin in one process. Experiments were carried out on pineapple skins that were still fresh and which had been stored for 24 hours. Pineapple skin is divided into 2 parts, namely the chopped and non-chopped parts. From pineapple skin that is still fresh and has not been chopped, 1.4 liters of juice are obtained. While the fresh pineapple skin that has been chopped is obtained as much as 1.6 liters of juice. From pineapple skin that has been stored for 24 hours and has not been chopped, 1.5 liters of juice are obtained. While the pineapple skin which was stored for 24 hours and had been chopped obtained 1.7 liters of juice.

Abstract

The rate of transportation development in Indonesia faces a significant increase. However, the increase in transportation rates is not in line with the increase in residents, especially for people with disabilities. One form of discrimination against people with disabilities is the lack of accessible transportation equipment for wheelchair users. The lack of service facilities makes people with disabilities feel insecure. The lack of facilities provided makes people with disabilities choose to use individual vehicles to continue activities like normal people. The purpose of the research on providing transportation facilities for people with leg disabilities is very much needed in carrying out daily activities easily and without obstacles. The design of a wheelchair user disability vehicle uses the VDI 2222 design method with 4 stages, namely planning, conceptualizing, designing, and completing. From the conceptualization session, 3 design concept variations were generated which were then assessed based on technical and economical aspects. From the test results that were tested, the average speed that can be reached by this wheelchair user disability vehicle is 30 kilometers / hour.

Abstract

Welding is a very important process in the industrial world and is not left behind in today's developments. Friction welding techniques that rely on heat by friction of two materials, besides this friction welding without the use of filler metal or electrodes and the processing time is not long, this friction welding is very good for solid objects such as shafts. At this time, a test will be carried out on the effect of variations in rotational speed and friction time on the impact strength of joints in AISI 4340 steel. This study will use lathes with variations in rotational speed parameters of 720, 1000 and 1400 rpm with times of 50, 70 and 90 seconds. The material used is AISI 4340 steel in the form of a solid cylinder and impact strength testing will be carried out using the charpy method. From the research conducted, the highest average results were obtained, namely at 1400 Rpm and with a time of 90 seconds with an impact energy value of 31.93 J and an average impact price of 0.398 J/mm2. While the lowest average value is at 720 rpm variation and with a time of 50 seconds with an impact energy value of 6.43 J and an average impact price of 0.079 J/mm2. So variations in the parameters of rotational speed and friction time greatly affect the strength of the material to be impact tested.
