THE IMPACT OF OVERALL EQUIPMENT EFFECTIVENESS ON PT FRAMAS INDONESIA PRODUCTION LOSSES ANALYSIS Yuli Suryandari 21 Desember 2016

Abstract: OEE is one of the most popular method in evaluate production performance to have a knowledge how much production losses caused by machine and production equipment. For this purpose, PT Framas Indonesia was selected as a case study. PT Framas Indonesia produces shoes outsoles which have several components. The components depend on shoes model. Main component produced by injection machine. Injection machine effectiveness measured with OEE ratio (Overall Equipment Effectiveness). OEE ratio considers available rate, performance rate, and quality rate. PT Framas Indonesia sets different OEE target for each project, the average is 80%. After collect all information related with machine and production equipment. All data will be processed by system which provides Availability, Performance, Quality, and OEE. System also presents information about type of downtime, time wasted caused of downtime, and then a conclusion about which factor most has contribution in not effective machine and production equipment. By this OEE data, also can get information about problem that happened in production process. So, the problem can be studied then management will take an action to find the bottle neck and solve the problem. The result of this study showed that Overall Equipment Effectiveness has significant impact on the reduction of production losses.

1.

Introduction Effectiveness is very important point in business. Production process which not effective will impact to quality, price, and delivery. A not optimal machine will produce low quality product. That low quality product will make cost of wasted material and other wasted processing cost, and in the end it will delay delivery to customer. By knowing effectiveness level, corporate can analyze how the production process run. The bottle neck of machine and equipment problem also can be known. Effectiveness measurement usually used by manufacturing company is OEE (Overall Equipment Effectiveness). Machine and Equipment ability measurement with OEE method, introduced by Seiichi Nakajima a spare part industry practitioners from Japan. In production process, not optimal production machine and equipment caused by 6 factors: 1. Breakdown, is production loses caused by stopped machine that impact to output. 2. Setup/Adjustment, is production losses caused by setup or adjustment machine and equipment setting when in case of product model change. 3. Small stop, is production loses caused by machine error or machine idle time. 4. Slow running, is production losses caused by machine and equipment run slower. 5. Production defect, is production losses because of product defect and rework. 6. Startup defect, is production losses because of product defect in startup machine. These factors classified to 3 categories of OEE measurement: Availability (Breakdown & Setup/Adjustment), Performance (Small Stop & Slow Running), Quality ( Production & Startup defect).

2. Literature Review Overall Equipment Effectiveness (OEE) is measurement tools of performance related with availability, production process, and quality. OEE Formula: Availability x Performance x Quality Availability=( (Machine Hours-Down Time)/Machine Hours) x 100% Performance = ((Cycle time x Output) / Machine Hours) x 100 % Quality = (Good Product/Output) X 100%

Note: Cycle time is time needed to produce one item. Pomorski (1997) said, available rate measure machine and equipment maintenance in running condition. Performance rate measure how effective production machine and equipment. And quality rate measured production process effectiveness to minimize scrap, rework and yield loss A study titled “ OEE and equipment effectiveness: an evaluation” authored by A.J. de Ron and J.E. Rooda, purposed to evaluate OEE and the difference with E (Equipment). The result of study is OEE is machine and equipment effectiveness measurement together with effect of before and after machine run. It means OEE not only oversee the status of machine but also the impact of before and after when machine and other equipment run or used. Instead of E only measure the machine effectiveness. (A.J. de Ron and J.E. Rooda, 2005). In another study analyze more general topic that is TPM titled ““Improving Overall Equipment Effectiveness by Implementing Total Productive Maintenance in Auto Industry” written by Prof. A. Bangar, Hemlata Sahu, and Jagmohan Batham. The conclusion is TPM can solve 80% production issues and increase OEE. TPM not only increases production effectiveness but also organization effectiveness related with productivity, quality, cost, delivery, safety and ethics. (Prof. A. Bangar, Hemlata sahu, Jagmohan batham, 2013).

This study is conducted to learn how much loses caused by not effectiveness production machine and equipment, and which activity has the most impact with production machine and equipment effectiveness in PT Framas Indonesia. This study purposed to explain hypothesis “Overall Equipment Effectiveness has a significant influence on production losses.” 3. Research Method Population in this study contains of all item produced in Fall Winter 2016 and Spring Summer 2017 seasons PT Framas Indonesia, start from August 2016 until November 2016. There are 29 item products in that seasons. Contains of 13 types Heelcounter (3 different machine used), 9 types of outsole, and 7 types of accessories. For each item will be calculated how many output, defect, machine hour, down time, availability, performance, quality, and other factors related with production machine and equipment effectiveness. After all data collected and examined. The next step, calculate whole OEE data. In this step we can make a conclusion how much production losses caused by not effective production machine and equipment and what is the bottle neck. 4. Result and Discussion Based on production data from Augustus 2016 until November 2016 we can get information to calculate Availability below: No

5. Conclussion Based on data shown in this study which related with Overall Equipment Effectiveness and production loses in PT Framas Indonesia. Hypothesis “Overall Equipment Effectiveness has a significant influence on production losses.” accepted. This statement based on data that shown low OEE ratio impact to material losses caused of defect. By OEE system we can know what the problem that make production machine and equipment not effective. The big five problem of not effective production machine and equipment are: break , mold change, shortage component, setting, and color change. In my point of view to reduce not effective production machine and equipment production, factory better make an investment of automatic machine and equipment to make a shorter mold application time. And another suggestion is maintenance department must always do a periodical maintain to optimize machine and equipment.
