PT. FSI is a company engaged in the automotive sector. Increased demand and efforts to meet customer satisfaction, then encouraging companies to continue to make various improvements including the shipping department, which is to facilitate the delivery of products to customers. One of the causes of the delay in the delivery of products to customers (delay delivery) is that there is a problem in the pre-delivery process, namely the storage conveyor machine. A storage conveyor machine is a machine that connects from the results of the production process to the temporary storage of goods which are then put into trucks to be sent to consumers.<br />The objective achieved in this study was to analyze the causes of the delay delivery in the process of shipping car seats on conveyor storage machines and make improvements to reduce the jammed base pallet frequency on the storage conveyor machine using the six sigma method. Based on the results of the research and analysis that have been carried out, it turns out that the case of the jammed base pallet on the conveyor storage machine is the cause of delay delivery to the customer and then make improvement to overcome or reduce the frequency of jammed base pallet problems on the storage conveyor machine by adding sponges to the shaft roller conveyor. The addition of sponge rolls is intended to increase power when moving base pallet between stations.

The export demand for Electoric Control Unit (ECU) products, which continued to increase by approximately 25% in December 2014, made the company have to review its production capacity. Based on current production capacity data, it is known that the process cycle time is 64.9 seconds while the takt time needed to meet consumer demand is 39.4 seconds for the first production line. With working time included in working hours overtime, this first-line capacity cannot meet production demands. Work measurement is done to get actual time data for capacity calculation. Man machine chart is one of the tools used to determine the production line capacity with the current number of machines and workers. To be able to fulfill the production demand, a capacity design with 2 proposed improvements is carried out, namely: adding a working time of one shift for the first production line or balancing work time between lines. By calculating the results obtained and the costs incurred, the proposal for balancing work time between lines becomes more effective to do.

PT.S is a metal pressing company that produces spare parts for the automotive industry. The increasing number of new companies, encouraging the company to make improvements continously, one of which is by reducing the processing time. The problem that occurs is the frequent occurrence of late pulling stocks in the finished product inventory area. One of them occurs in the Cap product (C1805-009) within a period of 6 months (October 2017 to March 2018) 16 times the stockout in the finished product inventory area. In addition, an increase in demand requires companies to do various ways, including adding four inspectors on each shift. This study aims to analyze the flow of production processes and waste of time with a simulation approach. Based on the simulation results using the Promodel software, it is known that the work station that is the cause of flow congestion is the inspection work station. Proposed improvements in simulation results also showed improvements, namely the reduction of processing time by 330.66% and the reduction in the number of operators by 50%. The simulation results can be considered by PT. S to improve the flow of the Cap product manufacturing process (C1805-009).

In Malaysia, the Road Transport Department (RTD) is one of the public sectors facing the issue of having excessive waiting times at their service counter. Various alternatives have been proposed to address this problem, such as implementing an e-government service via the official RTD portal and creating other units so that the demand can be segregated, which also involves the creation of other agencies including myEG and UTC. However, the problem has persisted and has even become one of the most urgent policy issues that plague the RTD. Thus, this study aims to propose an online system that will help manage queue during the service and therefore optimise the waiting time. Several methods were employed to achieve the objectives, including conducting semi-structure interview, observation, and time study at RTD Bukit Katil, Melaka, developing the online system with Adobe Dream Weaver, Oracle SQL Developer software, and Adobe Cold Fusion, and validating and verifying the system using usability studies and questionnaires. The first online system involves an online queue number booking system. With this developed system, clients can use an online system to book their queue number. Furthermore, this system provides clients with the duration of the waiting time so that they can be present at the counter in time before their assigned service. The second proposal involves utilising an online queue booking system. With this system, clients can book their appointment according to the specific time with the RTD staff. This system also makes it possible for the client to come and to be serviced on time. This system aims to optimise the waiting time at the RTD, improve customer satisfaction, and serve as a reference for other government agencies so that their services can be improved

Food factory is a chemical trading and processing company for semi-finished food. One of the processed foods produced is jelly powder. The problems faced by food manufacturers are how to reduce the occurrence of product defects and the length of product mixing process that is 180 minutes for A-type 147 jelly. Proposed improvements are made by the Failure Mode and Effect Analysis (FMEA) method where defective products occur at most hardness and syneresis parameters and are caused by 4 elements namely method, environment, human, and material. In this proposed improvement, additional methods are carried out by reconsideration after the raw material is grinding (puree) because in this process additive raw materials which are free flowing will be reduced due to exposure to air, added temperature control devices in raw materials, training on raw materials, and search for new suppliers with the same specifications. At the reduction of processing time, the mixing time is 150 minutes, so the food factory can reduce the mixing time by 30 minutes.
