Abstract

To control the production quality in terms of product weight, PT. X needs a standardization in production process. The weight standardization will help ease stocking process for both the company and the distributor. This research is used on the hollow product with chain type A with gold levels of 70%. Some of the products weight are not constant due to the variation of shrinkage percentage in every production process. The solution for this problem is to reduce the variation of shrinkage percentage levels in every production process using PDCA method. The improvement results obtained from PDCA method is shown on hammering, hollowing, and bombing process. On hammering process, a decrease in the shrinkage percentage variation is done by controlling the wire’s thick shrinkage percentage 15%-20% for a 5% shrinkage percentage. The percentage of necklace on hollowing process can’t be controlled, as a result an improvement is needed by giving an accurate range percentage standard, 49%-52% for chain A with gold levels of 70%. The weight shrinkage percentage in bombing process is depending on the size of small, medium, and large chain respectively 4%-5%, 5%-6%, 6%-7%.

Abstract

This research is originated from the current efficiency level of product distribution in PT. X which is considered low. This motivates the company to consider other transportation to distribute their products, which is train. PT. X sees train as a new opportunity as now there is double track in the system. On the other hand, train tends to have cheaper delivery costs than truck as the delivery distance increase. Method used to analyze the efficiency of both transportations is simulation. Observation has been made and the results shows that 50,55% of delivery route in Java and 77,97% of delivery route from Java to Sumatera can be replaced by train. Improvement and solution has also been proposed as a support for train distribution system so that the increase of overall efficiency can be achieved. The analyze of the system improvement shows result that the use of two point railway stations will reduce overall cost by 4,70%, while the use of three point railway stations will save overall costs by 5,02%.

Abstract

PT. X hasn’t yet measured output rate in production process, so company would like to measure the actual output rate. The measurement and effort to increase the output rate is performed for Merbau, Bangkirai, and Torem wood species on Line Preparation that consists of Planer, Crosscut, and Ripsaw process. Actual output rate in Planer for each wood species are respectively 0,0676, 0,0510, dan 0,0565 m3/menit. Actual output rate in Crosscut for each wood species are respectively 0,0260, 0,0298, dan 0,0257 m3/menit. Actual output rate in Ripsaw for each wood species are respectively 0,0305, 0,0315, dan 0,0318 m3/menit. This actual output rate is not optimal yet, could be seen from the Availability Ratio on Line Preparation that’s below World Class Company’s Availability Ratio (90 %). Availability Ratio in Planer for each wood species are respectively 72.60%, 81.91%, and 82.96%. Availability Ratio in Crosscut for each wood species are respectively 62.89%, 67.93%, and 64.08%. Availability Ratio in Ripsaw for each wood species are respectively 73.99%, 74.34%, and 74.33%. The effort to increase the output rate is then compiled such as design of additional tools for production machines, Work Instruction arrangement, and layout change in Line Preparation.

Abstract

This paper discusses about the change of yoke line system production. Yoke line production uses push system, which is DPS (Daily Production Schedule) and assembling line process uses pull system, which is kanban. Pull system and push system in one flow process can cause problem in inventory fluctuation. The goal of this research is to change the production system yoke machining at PT Inti Ganda Perdana from current sistem DPS into kanban system. This change is done by using Part Information Flow Chart (PIFC) to illustrate the production flow and the formulation to compute the circulation of kanban population each month. The use of kanban cards will make yoke line production  become pull system
