Abstract

PT. Dewata Cipta Semesta is a company which focused in sawmills, wood products produced in the form of cut (sawn timber) for building’s materials or furniture’s raw materials. The Warehouse system at the company is still very simple and has many weakness that cause some problems in the company such as the difference between the stock and the physical stock in the warehouse as well as the lenght of the process of unloading. Based on observations and data analysis on company, there are some problems that result in differences in stock and phusical as well as the duration of the process of unloading are: the arrangement of goods in the warehouse are not grouped in detail, two warehouses head leads, and grading process is carried out when loading. Warehouse management system improvement is done to minimize the  difference between the stock and the physical stock in the warehouse as well as accelerate the process of unloading the goods. Warehouse management system improvements made are arrange of the raw material warehouse are grouped by type and diameter of the timber , the warehouse material classified by type , grade and size of the timber , making the Standard Operating Procedure for the warehouse staff. For make the system running properly also proposed to appoint only one head of the warehouse so that there is clarity on the duties and responsibilities of the warehouse.

Abstract

PT. X is a company that processed log wood into timber products with size, type of wood, and the shape of the profile are produced depends on the buyer’s order. The company needs the process with a machine that can work continuously without any obstacle in order to meet the demand. Moulding machine in PT. X has downtime with an average 13,22% which the company want to reduce it. The main cause of downtime on the moulding machine is the changeover and breakdown. How to reduce changeover time is by using the method of Single Minute Exchange of Dies (SMED) and reduce frequency and time of the breakdown by making preventive maintenance schedule based on the MTTF value. The proposed improvements to reduce changeover time is doing some activities before the machine stops, making a new storage for tools and ring, and do the parallel changeover. The proposed improvements using the method SMED when applied can reduce changeover time with an average decrease in time estimation of 33,26%. Preventive maintenance schedule on the moulding machines based on the simulation results within a year can reduce downtime due to breakdown with an average of 57,55%.

Abstract

PT Schneider Electric Manufacturing Batam-Plant Electro Mechanic is a company that produce electrical parts. Changeover time on some bench in production floor are very high, That’s why it needs to be reduced and improved. The method that will be used are Single Minutes Exchange of Dies (SMED) This project started with observing all machine on production floor, and after that some machine will be chosen to be improved. Changeover time data will be taken from this chosen machine, and this data will be analyzed with SMED. The result from SMED data will become suggested improvement for each machine. Suggested improvement that able to straightly be done will be directly implemented to target machine.Improvement on bench Auto Tampo Print was able to reduce the changeover time by 47%. Estimate improvement on bench Printing Body XB7-2nd Life should be able to reduce the changeover time by 75%. Estimate improvement on bench Manual Checker should be able to reduce the changeover time by 44%. Estimate improvement on bench Coil Winding and Testing MARSILI should be able to reduce changeover time by 18%. Estimate improvement on bench Coil Winding DETZO should be able to reduce changeover time by 7.4%.

Abstract

PT.Lima Jaya is a company that engaged in the field of steel and metalworks. Currently, this company wants to build a new company that specialized in wiremesh production. Therefore, this research tries to design their facility layout for minimizing moment. Three algorithms are applied in order to get the best result. The algorithms are corelap algorithm, aldep algorithm, and blocplan algorithm. The result shows that the blocplan algorithm gives the best result with the moment 13579,4.

Abstract

PT ASKI is motorcycle component manucaturer. The average of total NG products for 2015 is 23,64%, while for dirty spots is 11,4%. The company’s NG targets for 2015 are only 12% for total NG and 6% for dirty spots. Therefore Quality Control Circle (QCC) methods will be applied to reduce NG products. The root cause for dirty spots are dirty environment in painting line facilities and tools. Operators dicipline to keep the environments clean also contributes to this problem. Therefore this research suggest to change sprayman’s gloves and masking tape paper. Dirty spots reduced by 1% from sprayman’s gloves changing, and 4% from masking tape -changing. Both result are not significant reduction to reach company NG targets. Other improvement sugesstion to be implemented are standarization on facilities and production equipments.

Abstract

PT. X is a industrial machinery company who supply their products to other companies of PT. X parent company. PT. X is currently experiencing major problems in terms of overload capacity and loading estimates are less accurate. This study aims to resolve both of these issues, which can lower the actual loading and improve the accuracy of loading estimation. Repairs carried out by estimating the reduction in loading by reducing the categories of working hours of others. A decrease in working hours of others are able to lower the actual loading is estimated at 24.23% in 2014 and 19.64% in 2015. The real proposal given itself are focus on improvement in the design department. Estimates loading then also carried out after fixing the actual loading conditions. Estimates loading at PT. X itself are having a great error when compared with the actual loading of existing, which amounted to 62.84% in 2014. Improvements loading estimation is done by using optimized manhour quota where uncertainty weight is the most important thing to its result. The resulting error rate amounted to 32.23% for the project loading, 9:48% for the total loading, and 6.78% for the total loading with repairs.
