Abstract

Honda Sales Operation Mataram is a company engaged in distribution, retail and vehicle maintenance workshops. Existing workshops become a job for some communities and help improve the economy of the community. It is an important concern considering that it is the mechanics who are the main spears in service. From this, a company needs human resources that are able to work effectively and efficiently. To produce human resources that work effectively and efficiently, proper human resource planning and management is needed to encourage the achievement of the company's vision and mission. In planning and managing time it is necessary to take measurements of working time and update existing resources or the need for a tool to accelerate the pace of productivity in the company. One of them is in the oil shock and seal shock changes, and made TsA-1 (shock absorber tool) to make it easier for mechanics to work and know the comparison of time in completing a job, where the normal time obtained by using ordinary tools in oil shock changes is 39.38 minutes and the normal time obtained using TsA-1 (shock absorber tool) in shock oil change is 33.52 minutes. So the mechanic is faster to do his job using TsA-1 (Tool shock absorber), where the time difference is 5.86 minutes. The standard time obtained using a regular tool is 41.45 minutes and the standard time using TsA-1 (tool shock absorber) is 35.28 minutes. Mechanics using the TsA-1 (shock absorber) tool are 6.17 minutes faster than regular tools. And for the replacement of seal shock obtained a normal time of 53.36 minutes with a regular tool, 51.70 minutes using TsA-1 (Tool shock absorber). Mechanics are faster to do their work in 1.66 minutes using TsA-1 (Tool shock absorber). The standard time of seal shock replacement with a regular tool is 56.16 minutes, and 54.42 minutes using TsA-1 (Tool shock absorber). Mechanics using TsA-1 (shock absorber) are 1.74 minutes faster than regular tools.

Abstract

The minimum thickness of vertical type pressure vessel of column type distillation, must be planned in accordance with the recommended code of ASME (The American Society of Mechanical Engineering) VIII Div 1. Based on this code, the study aims to determine the feasibility of a pressure vessel that used by PT Pertamina (Persero). For this reason, and to be able to use this ASME code, various data was needed, especially the data sheets and some required data from the field. Based on the data that has been collected, it is then processed and was made a 3D modeling and was simulated using Autodesk Inventor software to test its feasibility. Based on the results of the study, the minimum thickness was obtained, namely head 13.66 mm, shell 13.69 mm, and skirt 3.47 mm, respectively. Taking into account the availability of materials on the market, namely SA-516 Grade 70, the recommended thickness of the head and shell sections was 14 and 5 mm, respectively. From the results of the safety analysis, it was found that at the stress of 0.217, 0.197, 0.196, and 0.195 MPa, the Von Mises stress that occurred ware 0.249; 0.226, 0.225 and 0.224 MPa. From these data, based on the distortion energy failure theory, the head and shell materials which have yield strength of 260 MPa can be categorized as very safe because it does not exceed the yield strength of the material used.
