Abstract

Feasibility analysis is carried out in order to ascertain whether a business activity is feasible based on several aspects. In general, the aspects analyzed are technical feasibility, market feasibility, management feasibility, financial feasibility, legal feasibility and social feasibility. The financial analysis is carried out with several criteria in the form of Net Present Value (NPV), Break Even Point (BEP) and Payback Period (PP) and risk analysis. The total value of income earned per month is Rp. 80,228,000. The value of the investment interest rate is 11.4%. The analysis is carried out based on the calculation of NPV, BEP and Pacback Period so that the data knows whether this industry can be declared feasible or not. After calculating the tofu industry, the NPV value of Rp. 217,587,161. Based on this, it can be seen that this industry can provide a net income in 10 years of Rp. 217,587,161. Because the NPV value is greater than zero, this industry is declared feasible to run because it is positive. the total cost of production is Rp. 53,934,985 per month and the principal return for the selling price is Rp. 2020 per unit. Meanwhile, from the calculation of the Payback Period value in the tofu industry, it was obtained for 3.87 years, this value indicates that the business can return capital before the age of the project is over and this makes this industry also feasible to run. In risk analysis, the highest risk is on equipment and business permits. there is not any yet. Risk parameters, the equipment used is still traditional, if you want to improve, you can replace some equipment using a more automatic machine because the work process is carried out without using a division of tasks and it is better to immediately arrange for a business license

Abstract

PT XYZ is a company engaged in the wiring harness assembly industry that supplies products to automotive companies in Indonesia. The product of this company is a variant of the part number wiring harness, each of which has a different processing time and employee needs in the assembly process. In the production process for Part No 22-66779-00, PT XYZ divides the work line into three parts, namely the head assembly process (assembly of the product head), the body (assembly of the product body), and the end (assembly of the product tail). The work is conducted based on these parts by many manpower. The problem is that because social distancing is applied, work efficiency in each production line becomes less than optimal. Work productivity decreases and the finished product is past its delivery deadline. In this study, we analyze two scenarios of assembly work on wire harness products. The first scenario is to assemble the head, body, and end separately as PT XYZ has done in the field. While the second scenario is to assemble the heads separately and then carry out the assembly process with the assembly results from the body and end lines (mix body and end). It is resulting in a more efficient assembly process with a lack of time used. The transformation makes improved total time in all the activity processes faster in 2756.38 seconds. The productivity has an increase of 10% than using scenario 1.

Abstract

PT ABC is a company that produces various types of wire harnesses to produce cable assemblies. Wire harnesses are used in a wide variety of electronic products, such as motor vehicles, airplanes, industrial machines and household appliances. In this study the product that will be the object of this research is the wire harness assembly PN 03230462-0101 which is included in the ASM-AS cable project which has a long assembling lead time, this is because this PN is composed of several small PNs, namely PN 03218291- 01, 03218572- 01, 03218569-01, 03222900-01, 03218576-01, 03218574-01, 03223128-01, 03230390-01, 03230391-01. Small PN must be assembled first, so the time required will be longer and the process is quite complicated, there is still no clear work instruction in the cable assembly process, another problem is production efficiency which is still lacking based on company data from each each operator's actual production line that works is greater than the allocation of operators that should be. So that conditions like this cause a decrease in productivity and profits earned by the company. Project cable ASM-AS PN 03230462-0101 is one of the processes that will be improved using a manufacturing cycle efficiency approach. The number of value-added activities is 2,384 seconds, while non-value-added activities are 2,565 seconds, impacting productivity and MCE by 48%. The act of reducing non-value added activities to 987.30 seconds increases MCE to 68% with production flow optimization, automation and stock management
