<![CDATA[Abstract: PT Y is one of the companies in Surabaya engaged in manufacturing cigarattes. PT Y want to identify the waste so that it can be improved continuously. PT Y believed that the process has the potential to improve intra transportation process. Identification of waste to the process intra transportation especially performed on process delivery of PPIC TAC and PMD. The method used to identify the waste is value stream mapping. Value stream mapping that aimed to describe the process as a whole and reduce the lead time of a process. Waste that was found in the process of intra transportation is waiting, transportation and overprocessing. Proposals made reduce the lead time of each process. Lead time delivery of tobacco and clove from PPIC TAC to PMD successfully reduce by 2.56%. Lead time delivery of sliced tobacco from PMD to SKM successfully reduced by 46.73%. Lead time delivery of sliced tobacco from PMD to SKT successfully reduced by 2.59%.]]>

<![CDATA[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%. ]]>

<![CDATA[This research is a case study conducted at PT. Bondi Syad Mulia, which is a galvanishing services company. Production planning at PT. Bondi Syad Mulia combined with production department, so that the work does not focus and cause some problems in production planning. The proposed planning system is set up the PPIC department, so that production planning does not interfere with affairs that must be done by the production department. Another issue that arises is the production delays because there is do not have a good system of production scheduling. Determine the right scheduling for a company is very important, but not easy, especially for a service company that manufactures a wide range of products. This thesis aims to get the system scheduling to minimize makespan, thus increasing the amount of output produced. The method used to achieve these criteria is Algorithm Campbell, Dudek, and Smith (CDS) and Shortest Processing Time method (SPT). CDS scheduling algorithm results provide several alternative job sequences that generate makespan value is almost the same, but there is a job sequence that produces the smallest makespan value compared to other alternative job sequences.]]>

<![CDATA[PT. XYZ is a company that produces shoe. This study is subjected to reduce expired chemicals because it was keep too long in finishing line and to design a safer and ergonomic trolley. The amount of expired chemical due to there is no standard scheduled for distributors to distribute chemical in the finishing line so that many chemicals are stored in line and finally expired. The trolley is now considered less secure because there is no buffer on the front of the trolley thus allowing the jerry can to fall. Chemical distribution schedule will be made based on work measurement method. The result of this work measurement is that chemicals will be distributed for an hour so that distributors will distribute chemicals seven times in one work shift. The number of chemicals allowed to be in the finishing line is also limited by the need for chemical for one hour so that no chemical is wasted due to expired. The new trolley will be made based on anthropometry data to make it more comfortable and safe to use.]]>

<![CDATA[Currently, PT. Adicitra Bhirawa wants to increase their production capacity from 120 truck boxes per month into 250 truck boxes per month. The increasing of production capacity is applied by changing their production system from the piecework production system into line production system. The line production system is more efficient than the piecework production system in terms of the worker productivity. Line production system is designed using two heuristic methods of line balancing, Kilbridge-Wester and Helgeson-Birnie. The result shows Kilbridge-Wester gives the better result with 15 workstations. The proposed line production system can achieve the production target and increase the monthly worker productivity from 5.7 truck boxes/worker to 11.9 truck boxes/worker. A proposed plant layout is applied in order to support the new line production system.]]>

<![CDATA[PT XYZ is having difficulty in giving the exact completion time. Sales department always says that the order will be finished in eleven working days. Because the promised processing time always constant, 22.27% of the orders between June 2014 and November 2014 are late. Therefore, the aim of this research is to produce a system for production planning and inventory control, so that the company can estimate completion time accurately. The improvement is the company must estimating completion time before determining processing time in the sales order. Therefore, a detailed production schedule that can be accessed by sales department is needed. Scheduling is created by using the first come first served method, and paying attention to the raw materials availability. The lot size for ordering raw materials is determined by using fixed order quantity method. Production report is created more detail by reporting the actual production daily. The implementation of the improvements can reduce order fulfillment delays, because the processing time in sales order is determined by considering the remaining capacity. The scheduling is made based on the actual condition, therefore can be used to estimate the remaining capacity. The production report can also be used to check whether an order is produced according to the schedule or not.]]>
