The energy density of nearly three times that the gasoline will become alternative energy for the future, especially for large-scale needs. Indonesia is an archipelago country where 2/3 of it is water. Water can separate the H2 and O2 elements through an electrolysis process with a purity level above 99%. Indonesia is also awarded as a tropical country where the sun shines all year round. And the electrolysis process can use this free energy to separate the Hydrogen and Oxygen. This paper will inform the results of a combination model research between photovoltaic and Hydrogen production systems to produce Hydrogen gas in a pressure cylinder every 10 m3 with the pressure is 30 bar. Simulate each model in certain areas on Java Island. Then calculate the photovoltaic models based on the hourly irradiation rate throughout 2019. The average electricity consumption required for the calculation of H2/kg production is 49 kWh. While the measures for the LCOH sensitivity analysis use 4.1-4.75 kWh/Nm3 or 46.3-52.8 kWh/kg. The Hydrogen economy is the ultimate goal from this research that the optimal model design selection with a discount rate of 10% and a lifetime of 25 years is the primary consideration. The modeling results show that the fourth model (RPV 10 MW Banjaratma) is the most optimal in producing Hydrogen in terms of CAPEX/kW, Opex/kW/year, Power Consumption, LCOH, Income, and Residual Value/kW after 25 years running.","PeriodicalId":129225,"journal":{"name":"Proceedings of the 4th Asia Pacific Conference on Research in Industrial and Systems Engineering","volume":"25 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":"123344179","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}

Piping is an important piece of equipment in the oil and gas production facilities; therefore, the piping inspection plan should be well prepared. An integral part of inspection plan development is a piping circuit; it allows an inspector to manage the necessary inspections, calculations, and better recordkeeping. A problem faced in piping circuit development is the need for relatively many working hours and variability results. Although this problem is often encountered, piping circuit development generated by manual work is still common in practice. To overcome the issues in the piping circuit development, therefore a k-prototype algorithm was introduced. A k-prototype algorithm was used to accommodate the shortcomings in grouping objects with features comprised of mixed categorical and numerical data. This study concludes that the k-prototype algorithm is a promising clustering technique that can reduce the time spent developing the piping circuit and eliminating the resulting variability.","PeriodicalId":129225,"journal":{"name":"Proceedings of the 4th Asia Pacific Conference on Research in Industrial and Systems Engineering","volume":"92 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":"121329370","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}

Carbon capture and storage (CCS) technology is a promising alternative to reduce CO2 emission by capturing and storing the CO2 underground. However, the carbon market has undergone insignificant development as the CCS development level remains low. Acceleration of CCS development through better policies and regulation is critical to help achieving Indonesia's target to reduce GHG emission by 29% in 2030. Enhancing CCS development becomes one of the government goals. However, this goal is still arduous to achieve due to the complexity that arises in CCS development. CCS development is a complex system; uncovering such complexity could provide insights into factors that play significant roles and shed light on the possible policy options for better CCS development. Nevertheless, it is still less studied holistically from a systems perspective. This paper aims to analyze CCS development's complexity by developing a conceptual system dynamics model of CCS development in West Java as a case study. The conceptual model developed in this study has captured essential aspects of CCS development and identified three possible policy interventions to enhance the CCS development in terms of incentive, local site regulation, and environmental regulation.","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":"121473958","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 research will focus on eliminating waste to improve liquid soap line's OEE performance by analyzing waste using lean manufacturing tools. The methodology that used to solve this problem is by using WAM and VALSAT method combined with Six Sigma with DMAIC concept. In define phase, Value Stream Mapping was carried out to analyze the current condition in liquid soap line. Hereinafter, in measure and analyze phase, WAM and VALSAT was carried out to obtain the identification of waste and analyze the waste which causes low OEE in liquid soap line. This happens because of frequency of change over. Frequently changeover can lead low OEE due to production without output. The queuing of materials at the freight elevator is also the cause of low productivity. In the improvement phase, the author implement remapping product and production process redesign. After implementation, OEE increased from 47.7% to 55.5% and productivity increased from 96.7% to 97.9%. In control phase, the author suggests new total productive maintenance (TPM) as the control phase.

This paper proposes an integrated production and distribution planning in a multi-site plants model, in order to obtain optimal profit from production in each plant in a different location. This model uses a raw material fulfillment multi-suppliers scheme through a mixture of internal and external sources. Mixed-integer linear programming method is used for model optimization by considering production capacity constraints, demand constraints, supply constraints, production costs, logistics costs, and product revenue.

There are four types of users in this system: administrator, owner, marketing, and customers.

The decision-making process mainly influences the designed financial model. Hence, several famous MCDM methods have been used, but most of them still based on subjective decisions rather than objective decisions. The SIMUS is a MCDM method which produce a strongly objective decision rather than subjective.
