Abstract

Regional Minimum Wage (RMW) enhancement in Kab. Bogor is adequately high which in 2013, the RMW increasing 61% from 2012. RMW enhancement which not followed with manpower (MP) efficiency could became a disadvantage for company. The initial condition evaluation indicate the MP efficiency value is 45% and the line efficiency value is 70,5%. Total initial manpower allocation is 8 MP. Improvement executed which consider to customer demand and production capability. Evaluation result indicates there’s unbalance work load distribution of each MP. Improvement planned such as balancing the work load of each MP, machine modification, and re-layout the production area. The implementation based on shoujin principle’s resulted manpower saving from 8 MP to 6 MP, which the MP efficiency value is 53% and the line efficiency value is 85,8%. Standardized work did as well as the control item in order to stabilize the improvement process. The next step is the analysis of production capability to face the increasing of customer demand. This analysis concluded that production needed additional overtime and additional work shift (for November only) in order to fulfill the customer demand.

The percentage of unaccountable in the Secondary Processing Department during 2013 (early 2014) is 0.66%. There are three factors that affect that percentage. Those are processed tobacco spillage, tobacco stem, and another factor that has not been identified. The reduction of processed tobacco spillage and tobacco stem will reduce the percentage of unaccountable. Improvements that implemented are providing tools and modify some machines at Feeding to SKM Area, changing Stem Box’s setting, replacing broken parts from Stem Box, and providing sieving tools. Other improvement is implementing work instruction to prevent the clean processed tobacco spillage become waste. Improvements that implemented had reduced the percentage of unaccountable and had increased the Yield Secondary Processing by 0.13%.

Abstract

PT. X measures internal customer satisfaction using an index called Internal Supplier Service Rate (ISSR) monthly. One of the order intake in PT. X is material that called as material shipment. Currently, Order intake for material shipment was increasing, but the increasing not in line with the ISSR. PT. X only achieved ISSR as 89,5% in 2013 which target is 95%. This final assignment attempts to increase ISSR in material shipment activity. The proposed improvements are standar work flow, material forecast for Supplier, coordination between company and Supplier, and an additional staff for material shipment. The proposed improvements are implemented and the ISSR increases to 97,5%.

Abstract

This study discuss about XCSPA product’s work cell with lean problem WIP after curing process with the maximum location capacity 2640 pieces. Quality issue with main problem contact resistance has resistance value above 25 mΩ, will impact to product function. This study objective is doing improvement to work cell with Lean Six Sigma Method, for improve lean problem and quality issue. In this research, DMAIC is used to solve the problem, however we did not discuss the Improve step. Value Stream Mapping tool used for knowing value added and non-value added process with improvement opportunity. Quality tool using Process Failure Mode & Effect Analysis (PFMEA) for finding cause of problem and potential problem can be happened in XCSPA Work Cell. Reduction of WIP by rearrange WIP quantity between process that will reducing about 85.49% WIP quantity from VSM current state WIP quantity. Quality issue eliminated by change and modify production process. Eliminate quality issue will impact to CNQ reduction for the reject product. Target achievement stated has accomplish that was reduction of PLT from contribution of WIP reducing, otherwise MDR, PRR still can’t be monitored. There’s 26 improvement suggestion, with 11 suggestion done, 7 suggestion in progress, 5 suggestion not yet implemented, 3 suggestion aborted.

Abstract

PT. Surya Putra Barutama is a company that produces trucks and the others heavy equipment which Dump Truck as their main product. In order to maintain the customer’s satisfaction on supplying a good quality product, the company has obtained ISO 9001:2008 in 2009. It shows the company has implemented a good quality management in accordance to the guidelines of quality standards. During the production, the company has the objective to produce a good product and having less number of defects to the product. However, the fact shows that the defect rate is still relatively high and even exceeds the standards and tolerances specified. This study aims to determine the quality plan  for each processes by using statistical tools that are useful to control the level of defective products. The results of the Pareto diagram analysis shows that the priority defect are Over Painting (63%), Dirty Painting (60%), Uneven Paint (51%), Rough Paint (43%), Less Paint (29%), Power Take Over (53%), Porous Welding (45%), SpakBoard (39%), Less Welding (26%). The next step is to find the cause of the above defects with cause and effect diagram. It results that the cause are derived from human factors/worker, working methods, materials/raw materials and work environment. The company can take these causes into consideration on applying the Quality Plan. Quality Plan describes the quality characteristics of each process and department have standards and tolerance limits. Quality Plan also describes how the inspection and work procedures. Tub Assembly Quality Plan, SubFrame Assembly Quality Plan, Component Assembly Quality Plan, Painting Quality Plan and Finishing Quality Plan has been prepared to improve the quality planning systems and reduce the amount of re-work at the finishing stage. Preparation of Painting Quality Plan is included with the Painting Work Instructions.
