Abstract

PT. X is a company engaged in the production of paper pallet packaging for exports. In the production process, PT. X implements Make-To-Order production strategies which would begin to manufacture if the company has received orders from customers. Recently the problems facing by company are the uncertainty lead-time delivery and uncertainty of demand from customer. Both of these issues resulted the ordering of raw materials were unplanned and further caused in delayed delivery of finished products to customers. Furthermore the use of conventional display board currently leads to human error either recording the customer orders or calculating the availability of raw materials.The objective of this research, to solve the problem, proposed decision support system or DSS which will helps the company to schedule procurement of raw material and helps to control raw material availability. Stage of designing the DSS is using the waterfall system development so that the process is done by sequentially developed for each phase of development.The system development process is starting from the system initiation, analysis, design system and implementation. To analyze process, used object-oriented approach which point in the making of models to help analyze and understanding the problem. Results from the study showed that the problems faced by company solved by implementing the safety stock and the procurement scheduling which integrates with early warning sub model, Material Requirement Planning (MRP) sub model and inventory sub model, into a web-based decision support system that can be accessed anywhere, anytime and accurately by authorized user. Safety stocks are used as a backup supply which will be used when the uncertainties of demand occurred. MRP sub model schedules the procurement and calculate raw material requirements based on Bill of Material. Inventory sub model with early warnings system will provide a reminder to the user if the amounts of raw materials available have reached a certain condition so that users can perform further actions to maintain the availability of raw materials.

Abstract

The painting process is one of the very important processes in the automotive motorcycle industry. One of the problems in the painting process is the occurrence of waste in the use of paint materials or ussualy referred as overquota, which is caused by the presence of waste in the painting process. The VSM (Value Stream Mapping) method was used to reduce the waste that occurs, identifying waste begins using the Waste Assessment model (WAM) to determine the percentage of waste. The identified wastes are 3 types of waste with the greatest weight, namely defect (30.1%), motion (16.1%), and waiting (13.1%). Next is the selection of detailed mapping tools using VALSAT (Value Stream Analysis Tools). The tools chosen are 2 tools with the greatest value. Analysis of waste defect using Pareto diagram shows the most dominant rejects are dirty, saggy, and thin, so further analysis is focused on the three rejects using p chart, fishbone diagram, and FMEA (Failure Method Effect Analysis) . The proposals given to reduce waste are replacing SOPs, repairing work station, and making checksheets and material collection forms. After the proposal is applied, it is found that PCE increases by 17% and the reduction in Manufacturing Lead Time value by 26.15%

Abstract

In the process of transportation it is very in accordance with the route, the route the mode / vehicle goes to the destination. Route about the number of vehicles and which locations are passed. PT XYZ is a company engaged in the fast moving consumer goods (FMCG), with fields that make the flow of goods going higher so that the distribution of goods becomes fast and frequent. The distribution process is carried out using 1 fleet in each customer. Currently in the process of distributing goods, companies still use utilities that are used, so that the availability of empty space in capacity still occurs and this makes transportation costs high. Combining (considering) some customers is possible, while considering the time window, capacity and some products. This study discusses the route by considering various constraints to get the route, the number of vehicles, increasing the utility of each vehicle and the optimal distance so as to minimize transportation costs. Using a genetic algorithm that is preceded by the nearest neighbour algorithm is used to resolve this complication. Later the route will be formed and get the number of vehicles, increase the number of vehicles and the optimal distance. These results make an increase in vehicle utility by an average of 35.317%, an increase in the number of vehicles by 34.05%, and a distance of 10.075% thus saving transportation costs by 26.56% from the initial conditions.

Abstract

Uneven workloads that occur in every process or every work station, impact on outcomes that are difficult to achieve and even fail. Or even if accomplished but by adding more effort, it creates new problems. This does not happen only in mechanical systems such as car engines or generators, but also occurs in human body systems. It can even impact psychological aspects that are difficult to measure such as jealousy among workers. This study consists of two topics that carry out simultaneously with the topic of workload and product design topics. The workload study, attempts to improve the uneven workload of cleaning service on the auditorium floor with the help of a self-sustaining floor cleaning tool. Begin by measuring the workload of cleaning service before this research implementation. Then ended with a measure again with staffing methodologies after research implementation. The product design topics attempts to reduce the amount of sensors which other previous research using 3 or 5 sensors to only 2 sensors that is LIDAR and Compass. This topics is using mechanum wheel straight on a NEMA 17 stepper as a simple drives system. The system can clean up to 252 m2 in 20 minute. It is expected that automatic floor cleaners can help smooth the workload of cleaning service so they don’t need to work very early long before office hour and no need to home long after office hour. Its expected to be applied to similar cases in other buildings.

Abstract

In providing high quality products requires a quality control planning so that the output can be good. Quality control in the production line is based on an inspection by a qualified acceptance of the product. This quality control method is done by flexibly placing the quality control station to separate products in the form of rework to be reworked and scrap to be discarded. Research discussing the quality control station allocation taking into account the inventory of work in process and product rework and scrap not exist, therefore the researcher intends to do so. The development of this model is done by developing the objective function to minimize the total cost of production. Total expenses consist of process cost, inspection cost, waiting cost, quality control station installation costs, rework cost and scrap costs. The goal is to find a configuration allocation quality control stations in the production line at minimum cost. From the results obtained inspection station allocation model that is able to minimize the cost of the assembly and the flexibly to changes in demand parameters, costs, probability of conforming and nonconforming proportions.
