Abstract

PT.X is a company that working on Fast Moving Consumer Goods (FMCG) section. This company has more than 100 selling area that located in all over Indonesia. There are various selling system or distribution system in this company and one of them is Pre Order system (PO). The vehicle types that used for delivery on this system are blind van, Colt Diesel Engkel (CDE), and Cold Diesel Double (CDD). The purpose of this research is to discovered route optimitation so it can shows how many vehicles are needed for the delivery. It also can decrease the operational cost for the delivery. This route optimitation simulation is based on the existing route but it had been optimized with arranging the delivery using the Nearest Neighbor Insertion (NNI) concept where the delivery route will be using the shortest route. This PO delivery system also using the combination of Vehicle Routing Problem with Time Windows (VRPTW), Vehicle Routing Problem with Heterogenouse Fleet of Vehicle (VRPHFV), and Vehicle Routing Problme with Multiple Trips (VRPMT).The result of this simulation is the total number of vehicles that can be decreased in one week are 34 unit. In Bogor, Ciracas and Pulo Gadung, 1 unit of vehicle can be removed for Senin until Thursday (1*4*3=12). In Sunter, there are 3 unit of vehicles that can be removed for Monday until Thursday (3*4) and lastly in Tangerang there are 2 unit of vehicles that can be removed for Monday untul Friday (2*5=10). The distances that should be taken are decreased from 9,604 km to 8,028 km with total duration 1372,01 hours when it actually should be taking 1484,3 hours. The reducing of distance and time become a great additional benefit for the company because the company can save more fuel that can also reduce the polution of CO2. For the saving of the cost in this simulation is from Rp. 948,017,052.66 become Rp.797,589,503.62.

Abstract

Inventory is the thing to consider in ordering. Inventories have a variety of properties, one of which is a level of decline. Many researchers have done research on multi-item inventory but not with inventory are deteriorating and assume constant demand. The real condition that occurs today is that the company sells multi-item inventory in the presence of stochastic deterioration and demand. The situation is approached by building a model of inventory simulation using real data in Pin'kan Bakery. The simulation model is done with the help of monte carlod simulation and evolutionary algorithm. This study will compare two ordering modes, namely continuous review and periodic review. The results show that the continuous review method is an appropriate ordering method for multi-item inventory ordering with stochastic degrees and demand.

Abstract

PT Toyota Motor Manufacturing Indonesia (TMMIN) is an automotive company in Indonesia that operates as a manufacturer and exporter of Toyota products and spare parts. One of TMMIN’s export activity is Component Part Order (CPO). CPO handling is done using the help of the system, but the current system has problems, which is the occurrence of system errors. The current system is also not able to display tracking order visualization so there is often a process delay occurs in handling CPO. Analysis of the cause of process delay is done using Toyota Business Practice (TBP) and Ishikawa Diagram. Improvements made is to design a new system so that system error problems that occur in the old system can be eliminated. The system is also designed to have an order tracking function so that every process of CPO handling can be recorded in the system. Improvements to deal with CPO operational issues are also designed in the system. Goals of this improvement is to achieve a smooth and on time CPO handling. Another expected advantage of this improvement is the saving of 2244 hours / year of work time required to solve the problem.

Abstract

This research was conducted to find the root of problem by using CP8211 natural color product as research object. The problem was identified with using lean manufacturing philosophy concept. The 5 Whys Analysis technique is used to identify existing problems. An outline lateness can occur due to two things, namely problems in scheduling and problems in the stamping process itself. Scheduling problems, whether errors in the determination of dates or errors in determining the length of processing time, can occur due to inaccuracy of operator scheduling PT. X itself. Processing problems can occur because the machine's working efficiency does not match the minimum engine capacity of 80%. Inefficient (under 80%) machines can occur due to several factors. The inefficient causes of the engine are identified by using the Cause and Effect Diagram. The results of this study indicate that the factors causing lateness that occur due to scheduling errors in the process of up-down stamping and engine damage are suspected due to engine age of more than 10 years. The solution provided for the scheduling problem is the scheduling operator of PT. X must be more careful in recording data that has been scheduled in order to avoid misunderstandings. The solution for machine efficiency is PT. X can replace parts of the machine that often damage with a new or replace the old machine with a new one. The new machine still uses the same workings as the old machine, which involves human labor to operate it.
