Sumberdaya Development is one of LPG agent partners of PT Pertamina. This company is assigned to distribute 3 kg LPG. The LPG shipment is carried out from Monday to Saturday. The shipment goes to 66 depots using agent vehicle which are registered in PT Pertamina. From the preliminary study, there were problems which related to the long-distance shipment, and the limitation of transportation and capacity.  In this research, the shipment routes of 3 kg LPG in PT IB is determined. Sumberdaya Development problems consist of the distance of the travel, the time of travel, and optimal transportation cost. Based on Clarke and Wright Savings Matrix algorithm, by considering the vehicle capacity, the distance can be minimized. The point of this algorithm is calculating the saving by measuring the available reduction of distance and time. It is done by linking the existing depots and making a route which is based on the largest saving value of the distance from the agent to the destination depot. Each route is optimized by WIN QSB software by using Branch and Bound method. A program to facilitate the determination of shipment routes by using PHP programming language is designed. The proposed route for the 3kg LPG shipment is 762.35km  with  33.58% saving, and the proposed time is 2929 minutes with 15.27% saving. The shipment schedule is designed from Monday to Saturday day to Saturday with each of 7 routes. This is better than the actual route used by the company.","PeriodicalId":30702,"journal":{"name":"Jurnal Optimasi Sistem Industri","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42273412","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

But if too much inventory, it will cause harm to the company because the company has issued a number of costs for treatment of the goods. In addition, the company's funds will be allocated to carry too much inventory purchases. Based on research that has been done, there are some problems faced by the Regional Water Company (PDAM) Tirta Sakti related to inventory management. The problem is the difficulty of PDAM Tirta Way office in determining whether certain types of goods are still available at eight branches or warehouses. This could be due to the unclear recording of goods in and out of the barn. In addition, other problems are frequent delays in the procurement process that resulted in running out of stock of goods in a warehouse in central and branch warehouses. This has happen because there is no clear safety stock that can be used as a basis when to re-order goods. The absence of a good coding system of goods also causes problems. This is due to the items contained in the warehouse is well organized neatly so many different kinds of goods are mixed with each other. As a result, the warehouse had difficulty in determining whether the item is still available in the warehouse or not. Therefore, inventory management information system design is to overcome the above problems. Inventory management information system design is done so that there is no shortage of goods in warehouse contained due to the existence of information system design is the central part can find out directly the number of stocks contained in each warehouse, when the goods are to be ordered, and how many number items to be ordered so that the ordering of goods can be directly carried out without waiting for the demand for goods by the branch warehouses. In addition, the information system is also equipped with a coding system so that goods are goods in the warehouse can be grouped according to the criteria, type and size specified.Keywords: information system, inventory, safety stock, reorder Point","PeriodicalId":30702,"journal":{"name":"Jurnal Optimasi Sistem Industri","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43166485","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It can only be realized if new technology is difussed and adopted. Adoption of technology in the processing of white pepper is still very low. It is therefore necessary to study with the aim to develop a model of agroindustry technology adoption process, and to formulate strategic policy for its acceleration. Model of measuring and predicting user acceptance of new technology is adopted from Unified Theory of Acceptance and Use of Technology (UTAUT) model. Mapping and prediction model technology adoption rates are expressed as a form of usage behavior. The model consists of two parts sub models namely intention to use sub models and support facilities sub model. To deal with vagueness in analysis of technology adoption, fuzzy inference system is used on mapping and level prediction of technology adoption.Keywords: technology, process, model, fuzzy inference system, agroindustry","PeriodicalId":30702,"journal":{"name":"Jurnal Optimasi Sistem Industri","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2011-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69209911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
