Analisis Penyebab Cacat Produk Keramik Tableware Yang Dihasilkan Mesin Dustpress Di PT. Sango Ceramics Indonesia Menggunakan Statistical Process Control (Spc)

PT. Sango Ceramics Indonesia produce ceramics type tableware (such a glass, bowl, mug, plate and others) using four different types of molding machines namely dustpress machine, roller, high casting presurre (HPC) and machine casting. PT. Sango Ceramics Indonesia suffered a decline in the quality of the product is shown by an decrease in yield number . on all a kind of machine . Dustpress machine decreased yield of 12,98 % , casting machine of 0.7 % , HPC machine of 12,39 % , and roller machine of 11,13 % .Reduction in the value of yield shown increase of a defective product resulted in the process of rework rise so that led to increase in the production cost . This research aims to identify the most amount of defective product based on engines and defective product types to get an alternative solution to reduce the number of defect ceramic. This research use method Statistical Process Control (SPC) with tools that use the pareto diagrams, fishbone diagrams, control chart and proposal of improvement 5W+1H. The highest number of defects occurred in the product is produced by machine dust press. Most defect prodct is a type of defect tobi (pinhole on the surface of the glaze penetrate into the body) with a percentage of 82,19%. The proposed improvements are given based on the analysis of the cause use cause and effect diagram by 5W+1H. There are six repair proposal for a cause deformed by humans , environment , machine , methods and material

Joint Economic Lot Sizing Optimization in a Supplier-Buyer Inventory System When the Supplier Offers Decremental Temporary Discounts

This research discusses mathematical models of joint economic lot size optimization in a supplier-buyer inventory system in a situation when the supplier offers decremental temporary discounts during a sale period. Here, the sale period consists of n phases and the phases of discounts offered descend as much as the number of phases. The highest discount will be given when orders are placed in the first phase while the lowest one will be given when they are placed in the last phase. In this situation, the supplier attempts to attract the buyer to place orders as early as possible during the sale period. The buyers will respon these offers by ordering a special quantity in one of the phase. In this paper, we propose such a forward buying model with discount-proportionally-distributed time phases. To examine the behaviour of the proposed model, we conducted numerical experiments. We assumed that there are three phases of discounts during the sale period. We then compared the total joint costs of special order placed in each phase for two scenarios. The first scenario is the case of independent situation – there is no coordination between the buyer and the supplie-, while the second scenario is the opposite one, the coordinated model. Our results showed the coordinated model outperform the independent model in terms of producing total joint costs. We finally conducted a sensitivity analyzis to examine the other behaviour of the proposed model

Manajemen Risiko Bagian Airside Menggunakan The Structured What-if Technique dan House Of Risk (Studi Kasus di PT Angkasa Pura 1 Cabang Bandar Udara Adi Sumarmo Surakarta)

Angkasa Pura Inc. is one company that is engaged in the management and operation of airport services and flight navigation. Angkasa Pura Inc. provides aeronautical and non-aeronautical services. Aeronautical services are services provided to aircraft and passenger .Each flight accident may causes fatal and unexpected losses. Statistically, nearly 80% of aviation accidents occurred at the airport. On November 30th, 2004 Lion Air Airlines with flight number JT 538 from Soekarno Hatta - Adi Soemarmo with 146 passengers crashed during landing at Adi Soemarmo Airport. This accident resulted in 26 victims died, 55 were seriously injured and 63 suffered minor injuries. Angkasa Pura I Inc. which branch at Adi Soemarmo Airport has not completed the project in 2014 amounted to 87% of the planned project on the work plan. If the project is delayed this may result in risks that can not be eliminated in the company. One of the causes of delayed projects can be caused by the shifting of the budget. This study uses the application of risk management phase of flight at airside at Angkasa Pura I Airports Adi Soemarmo. The method used are HOR (House of Risk), a combination of HOQ (House of Quality), FMEA (Failure Mode and Effect Analysis) and SWIFT (The Structured What-If Technique). At the risk of flight phase found 23 of risk event, 23 of risk agent and 19 proposed strategy to mitigate the risk. At the risk of work found 13 of risk event, 13 of risk agent and 8 proposed strategy to mitigate the risk The first priority of the strategy is the installation of CCTV at the airside

Penerapan Lean Manufacturing pada Industri Proses dengan Fokus pada Pengolahan Tepung Ikan

Opportunities of local fishmeal raw material derived from fish waste is enormous. Besides will not reduce the quality of fish meal, fish waste utilization will reduce the impact of fish waste which is currently not managed properly. In CV Pendawa Kencana Multi Farm, low production of fish meal is caused there are a variety of waste in the production of fish meal. In an effort to increase productivity, activities that could increase the value-added of products (goods and / services) and eliminating waste is need to know. The appropriate method to analyze the activities efficiency and waste and also optimize productivity of fishmeal processing is Lean Manufacturing.Lean Manufacturing approach is done by analyzing the waste with value stream mapping, determine the wastes and cause of wastes that have the greatest influence on the productivity of the fishbone diagram and suggest proposals to overcome such wastes.Results from this study show that the fishmeal processing efficiency of 11.63%. From these results was found waste in the form of waiting waste, excessive inventory waste, inappropriate process waste and defect waste. The proposed recommendations to reduce waste is by applying 5S, production level, and developing of standardized work
