A FEASIBILITY STUDY TO BUY METAL PLATE PRESS MACHINE IN PT. X Budiharsono, William While automotive industry in SEA market are growing rapidly, manufacturer hardly keeps up with the demand. Therefore, capacity upgrade are necessary to satisfy the market. While current capacity has a limit, new equipment sourcing is inevitable. To source a new machine/ equipment requires a considerable amount of capital expense. Therefore, to decide whenever the project is feasible or not, a feasibility study need to be conducted. Feasibility study is one of the most used tools for decision making, not only to secure and being one of the requirement analysis in financing project, but it also necessary to analyze the benefit and disadvantage of the investment project. There are three different focus of study within this research, there are market, technical, and financial aspect. In the market feasibility study, historical demand and business trends analysis will determine future state of market. Technical aspect will focus on material availability and machine compatibility to the available space in facility, product specification, and production capacity. While financial aspect will focus on the cash flow and break-even analysis to further determine the internal rate of return of the investment. In the end, this research has successfully shown the feasibility of all three aspect (market, technical, and financial) and lead to a prospective break-even point of two years period with 28% rate of return. Thus, concludes feasibilities of the project.

THE APPLICATION OF LEAN PRINCIPLES IN A JOB SHOP SYSTEM TO REDUCE THE MANUFACTURING LEAD TIME (CASE STUDY: A PVD COATING SERVICE COMPANY) Grafita, Elizabeth Steffina For the last two decades, lean strategies and its implementations has placed itself as a powerful tool in delivering countless success, especially in mass production, assembly line, and other low variety, high volume environments. This lead to a doubt of whether such approach is applicable in the counterpart of the environment: job shop service industry with low volume, high variety situation. Through a case study conducted in PT.X that firstly introduced PVD (Physical Vapor Deposition) coating service in Indonesia, the answer to this question would soon be unearthed. Value Stream Mapping (VSM), Product Family Matrix, and other analytical tools were deployed to evaluate and progress the processes existed, in which manufacturing lead time serves as the primary measurement focus. From Flow Process Chart constructed, it turned out that waiting times and distance travelled are mostly responsible for undesirable extension of lead time. As such, simulation approach was used to deliver one major improvement in non-machine layout rearrangement by considering resource and time limitation of instant actual implementation. To be exact, the result targeted by this final project was to attain minimum ten percent reduction of lead time. Although in the end simulation output fell short to achieve this projected goal figure; lean principles were proved to be robust in job shop system, so that it was very promising to deliver extended reduction in manufacturing lead time.

REDUCING CHANGEOVER TIME ON INJECTION MOLDING MACHINE BY USING SINGLE MINUTE EXCHANGE OF DIES (SMED) METHOD Mendila, Adyanto This thesis is aimed to reduce the changeover time of machine in injection molding process of a toy manufacturing. High changeover time in injection molding machine could give impact to the machine efficiency and flexibility. In order to overcome the root cause, the Single Minute Exchange of Die (SMED) is the first and foremost method to be done. SMED is a concept and method was developed by Shigeo Shingo to reduce changeover time. Before SMED method is applied, the observation and time study of the current flow process in injection molding machine changeover is conducted. Furthermore, some lean tools like 5S implementation cause and effect diagram, value added and non-value added determination are considered in reducing injection molding machine changeover time. Those methods can increase the efficiency of internal and external operations. By implementing those methods, there are many improvements can be achieved. The injection molding machine changeover time is reduced by 37% from the previous changeover time (from 39.62 minutes to 24.88 minutes). Furthermore, the 5S score is increased by 0.94 points (from 2.09 points to 3.03 points). As a result, the problem of high changeover time in injection molding machine and having additional cost can be overcome.

DETERMINING THE IDEAL RATIO OF WORKER AND MACHINE TO INCREASE OPERATOR’S UTILIZATION Putri, Ayu Pangestuti Chasanah This thesis is mainly focused on determining the ideal ratio of worker and machine to increase operator’s utilization in auto rooting process area. Low operator’s utilization could give impact to operator productivity and cost of production. Therefore, the ideal ratio of worker and machine should be determined to avoid excess resource. In order to determine the ratio of worker and machine, a time study should be conducted. By using time study the standard time of operator could be established, and it will be used to create a simulation model of ideal worker and machine ratio. There are three scenarios of ideal worker and machine ratio that the author made. Those three scenarios are compared by using Bonferroni approach to get the best scenario of ideal worker and machine ratio. The result of Bonferroni approach shows that the ideal ratio of worker and machine is one operator for three machines. By implement this ideal ratio, the operator utilization can be increased up to 26% and the operator productivity can be increased up to 67%.
