Pengembangan Model Pembentukan Sel dengan Kriteria Majemuk

Stages of designing the layout of the manufacturing cell involves three steps: (1) the cells formation, (2) designing the layout of the intracellular and (3) designing the layout of intercellular. This study made a model of cell formation. At this stage of cell formation, the criteria to be considered are the cost of an additional investment of machinery, material handling costs intracellular, intercellular material handling costs, cost of work in process and penalty fees under the machine utilization. Intracellular layout design stage, the criteria to be considered is the cost of work-in-process. While the design stage layout intercellular consider the cost of work-in-process. The performance of the layout of the cells was evaluated using a numerical example

Usulan Penentuan Strategi Pendistribusian yang Optimal (Studi Kasus : PT. X)

The purposes of this research is to analyze the optimal distribution system at PT. X. There are three alternatifs given. The method used is saving matrix method and Knapsack using distance and time data. This research is considered the traffic conditions so the distance matrix is transformed into time matrix. The result show the distribution route and sequence of optimal methods. Distribution route is obtained using Farthest Insert, Nearest Insert and Nearest Neighbor. The sequence of methods is placed saving matrix method at first and then Knapsack or vice versa. After this, the distribution cost is calculated for three alternatifs given. This cost calculation is considered pinalty cost which is the value of opportunity cost when truck is not fully used. The results of cost calcutation show, when considered penalty cost, the best alternatif is alternatifs three that deliveries all consumer demand with freight forwarding services. However, this penalty charge is not real value (not spending money) so the company does not consider the cost of this penalty. When calculating cost without penalty cost, the best alternatif is alternatif one that deliveries all consumer demand with the company’s truck. In the first alternatif, the best method is saving matrix distance – knapsack. This method aims to select nearby consumers then optimize the distribution fleet

Analisis Performansi Sistem Produksi Genteng (Studi Kasus: PT. XYZ , Cikokol)

This research discusses the proposed implementation of lean manufacturing system at PT. MONIER. PT.MONIER is a manufacturing company engaged in the production of tiles with 3 types of product that is Exeltile, Centurion tile and Elabana tile. PT. MONIER is using push system as their production system methodat the moment. Current state value stream mapping is made to see shop floor as a big picture. Calculationshows that current state Process Cycle Efficiency (PCE) is very low with only 4,51%. The company still farfrom “lean” because minimum requirement of a company called lean when the value of PCE more than30%. Meanwhile, current state Overall Equipment Effectiveness (OEE) is 79,98%. From the observation, itcan be found that there are many non-value added activity (waste) at PT. MONIER factory. From theidentification of waste using check sheet and cost calculation resulted by wastes, it was found that inventorywaste post the biggest cost with 92,8% of the total cost of existing waste. With further analyze, it is knownthat the root cause from inventory waste is due to the company allow overproduction and there is wrongphilosophy against inventory. Those root causes which has found before is to be eliminated with leanmanufacturing system approach. There are several methods that will be applied in PT. MONIER such as 5Simplementation and standarized work, then future state value stream mapping is made to see all proposedmethods in a big picture. In addition, this future state condition will be simulated to give a betterperspective. With the implementation of lean manufacturing system, future condition is as same as currentstate value condition. Future state Process Cycle Efficiency (PCE) is 4,51% and future state OverallEquipment Effectiveness (OEE) is 79,98%. This happens because the theory and methods of lean from leanmanufacturing system can only be applied on the assembly line and one piece flow

PT. XYZ is a company engaged in the field of packaging tissue with make- to-order system with four types ofproducts , namely toilet roll , napkin , handkerchief and facial tissue. On each work station of the fourthproduction line, occuring inefficiencies between workstations using a machine with manual work stations .Therefore, it is necessary to equity workload of each workstation and redesign of work stations that areexpected to minimize the amount of work in process . In this study, allocation of workstasion are made as aimprovement recommendation. Performance analysis conducted to see the efficiency of each of theseconditions . An increase in line efficiency of each production line. In this study, also conducted the analysisand design of work stations using software MannequinPro .

PT. XYZ uses a decentralises system for the delivery of products, where the delivery of products to consumers done by the dealer. PT. XYZ uses expedition logistics to deliver products to dealers. It is expected to make the shipping cost is high. This study changed the pattern of delivery of products directly carried out by PT. XYZ without going through dealers (centralises system). Then compare the lowest shipping cost of both systems. These results indicate that the system centralises can save shipping costs by 77% compared to a decentralises system
