Nevertheless, in conducting their business, farmers face risks, including climate changes, livestock accidents, diseases, and emergency slaughtering that reduce their income. Due to farmers' enormous risks, Indonesia's government issued a law of protection and farmers' empowerment (Law No. 19 of 2013), stating that agricultural insurance is one of the seven farmer protections. Cattle Insurance Program is one of the agricultural insurance forms of protection for farmers who experience losses in their livestock cultivation business by receiving compensation to be used as capital. However, this program has not provided an economical business scale for the insurance company that the government appoints. It can be seen from the high loss ratio of more than 200% on average since the program was first implemented in 2016, and this can affect the sustainability of the cattle insurance program. This research aims to develop a conceptual model that can be used to understand the structure and the causality between elements using a system dynamics approach. This model shows that loss ratio influencing factors are premium tariff, sum insured, the number of cattle participating in the program, a claim ratio, compensation, and deductible. This study results can be used to develop financial strategies and scenarios to decrease the loss ratio.","PeriodicalId":129225,"journal":{"name":"Proceedings of the 4th Asia Pacific Conference on Research in Industrial and Systems Engineering","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128238101","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}

{"title":"Inventory Management Based on Component Reliability Toward Uncertainty of Demand in Aircraft Spare Parts","authors":"Fauzul Rezy Oenzil, D. Ishak","doi":"10.1145/3468013.3468375","DOIUrl":"https://doi.org/10.1145/3468013.3468375","url":null,"abstract":"For the purpose of reducing the inventory costs, aircraft spare parts must be handled within a short Turn Around Time (TAT) due to these parts have unique characteristic with expensive prices. And for efficiency purposes, it is possible to reduce the aircraft maintenance costs by preparing the optimal spare parts supplies, because the aircraft maintenance in aviation industry has costs around 13% of the total operational costs. In the event of component failure while an aircraft is operating, the reliable access to parts and components is essential for airlines to maintain consistency in operations. Instant part availability, however, is not always guaranteed due to various kinds of factors. How airline operators must explore to minimize the disruption via various approaches they can adopt to manage the inventory. An event that delays occurred in an airline's operation is a vital or ‘no-go’ aircraft component failing during flight is also essential. This can result in an aircraft-on-ground (AOG) situation, with the aircraft unable to operate until repaired. The knock-on effect can include penalties, lost revenue and shipping costs. Inability to operate an aircraft even for a half-day can have large cost implications. While it is not possible to predict and prevent all component faults and defects, the sophistication of data analysis today, alongside evolution of parts supply processes, has allowed a number of failure and AOG events to be mitigated. Therefore, to ensure the maintenance effectiveness and use of several profitable assets, controlling the aircraft inventory becomes an important activity. The excessive spare parts inventory will cause high inventory costs and make an influence to cash flow. Meanwhile, if spare parts insufficient, it can cause flight delays or flight cancellations with high cost and a negative impact to the image of the airline. The right inventory model to get a right balance is important, because the aviation industry requires a large number of spare parts and some of which have expensive prices. A reliable inventory management must have regular stock controls or routine cycle counts. In order to control the spare parts inventory in the aviation as well as the maintenance department, there are several requirements that must be met. And to meet these requirements, a software solution is needed to substitute manual input into the administrative system. The research in this paper is focus on studying the stochastic inventory management toward uncertainty of demand in aircraft spare parts based on component reliability analysis, so that we can give data input to purchasing department for procurement.","PeriodicalId":129225,"journal":{"name":"Proceedings of the 4th Asia Pacific Conference on Research in Industrial and Systems Engineering","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128371179","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}

Improvements in the warehouse can be made by reducing waste and defects in every process (inbound, storage handling, picking and shipping). The Lean Six Sigma approach has been widely used in various industries and can increase productivity. This study aims to present an analysis of the application of lean six sigma in finished product warehouse operations with a discrete event simulation approach in order to obtain suggestions for improvements to reduce waste during loading process. Lean Six Sigma provides a structured approach through the implementation of DMAIC (Define, Measure, Analyze, Improve and Control) for analyzing a warehouse operation problem, diagnose its cause and generate improvement plan. Discrete event simulation is used in the \"improve\" stage to provide an evaluation of loading process improvement in product warehouse. Simulations are carried out in case studies of steel plate warehouse products where there is some waste during the loading process, including inefficient storage location and reshuffling during delivery. Improvement scenarios based on lean six sigma are simulated so that they can be implemented, in order to obtain a more systematic warehouse operation improvement design.","PeriodicalId":129225,"journal":{"name":"Proceedings of the 4th Asia Pacific Conference on Research in Industrial and Systems Engineering","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114412565","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}

Indonesia is one of the developing countries that conduct waste management for becoming a country with a sustainable environment. Waste management is a very important implementation system for upcoming on the excess supply of waste. Population growth is one of the factors that cause an increased supply of waste in some cities in Indonesia. Therefore to give a good impact, waste management needs to be done by local government or municipal governments. In its implementation, the governor established a policy to select the technology to manage waste by appropriate methods to determine the technology. Waste projection of Pematangsiantar City about 42,608,487 kg per year is used as base data in case study management of waste that will be formulated on the biomass power generation.

A growing of international port standards recognizes the need to standardize sustainable port development. Indonesia's government proposed a green port policy to meet this requirement. However, different views and interests make it difficult for the government to coordinate private stakeholders and the various economic sectors to support the policy implementation. This paper analyzes different perspectives from different actors to find potential conflict as the basis for the government collaborates among actors to accelerate Indonesia's green port implementation. Dynamic Actor Network Analysis (DANA) is used to define each viewpoint in the perspective diagram systematically. Each perspective diagram generates one hypothesis, and we get which actors with the potential to cooperate and which actors are not by confirming all hypotheses. This paper concludes that DANA can develop and promote multi-actor system arrangements that address all port-related stakeholders’ interactions.","PeriodicalId":129225,"journal":{"name":"Proceedings of the 4th Asia Pacific Conference on Research in Industrial and Systems Engineering","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134579044","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}

This awareness links to the essential knowledge that natural recycling will take a long time for particular waste, and each one will damage the environment. In Indonesia, rubber waste is another thing to which we must pay attention besides plastic waste. This rubber waste is mostly contributed by tire product: the vital part of a vehicle to run its movement function. End-user customers or the industrial sector could produce this waste. According to BPS (Statistic Indonesia; locally known as Badan Pusat Statistik) data, the number of four-wheeled vehicles continues to increase every year. With more than 16 million units at the end of 2018, an annual growth rate has reached 6.9% since 2014, suggesting that rubber waste will be in a linear amount and needs to be reduced. Particularly for tires, reuse of unused in the downstream (end consumers) is an effort to reduce waste. In contrast, in the upstream (industrial sector), waste reduction can be done by improving production strategies. A case study conducted on a tire manufacturer in Indonesia shows a strong relationship between yield and scrap rate, which of course, will have an impact on waste products. This paper aims to understand and analyze manufacturing's role in controlling tire waste due to failing products using a conceptual model with a system dynamics approach. This conceptual model can be used to evaluate manufacturing activities in producing waste.","PeriodicalId":129225,"journal":{"name":"Proceedings of the 4th Asia Pacific Conference on Research in Industrial and Systems Engineering","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131234478","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}
