This can be a non-military threat in the dimension of public safety because if it occurs, the resulting loss could be very large in terms of material or life. This study aims to determine the risk of fire and explosion at Indonesian gas station. Methods: The risk assessment method used is the Dow's Fire and Explosion Index in a simulated case. Results: The potential for fire and explosion or the value of the Fire Explosion Index (F&EI) in the simulated case is 110,828. The exposure radius is 28,39 m and the damage factor to the Pertamax storage tank is 63%. The large area of the Exposure is 24 m2 with an area of 96 m3 of the bunker building volume. The value of the loss suffered by the company in the event of a fire and explosion in the Pertamax tank is Rp. 403.908.076,97. Conclusion: The results of the study have a risk level that is classified as Intermediate, so it is necessary to control risks such as increasing active protection and is expected to be an input in efforts to safeguard against non-military threats so as to reduce the impact of risks and losses that occur in the Pertamax storage tank.","PeriodicalId":31435,"journal":{"name":"International Journal of Innovation in Mechanical Engineering and Advanced Materials","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42209608","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}

However, because one ton of Portland cement produces about one ton of CO2, the Portland cement manufacturing process has considerable disadvantages. As a result, an alternative to Portland cement appears to be required. Geopolymer is a new and environmentally friendly cementitious material that can be used in place of Portland cement. Chemically and mechanically, geopolymer concrete outperforms traditional concrete. The weight ratio of water to dry matter used in polymerization, as well as the weight ratio of sodium silicate to NaOH solution, have an impact on the compressive strength of geopolymer concrete. As a result, additional research into these variables appeared to be necessary. This paper specifically looked at how nanosilica and zeolite affected the mechanical strength of metakaolin-based geopolymer concrete. Nanosilica was added to metakaolin-based geopolymer concrete to improve mechanical characteristics. Furthermore, using zeolite in a metakaolin-based aluminosilicate source lowers the mechanical strength of geopolymer concrete while also lowering the cost. The optimal weight ratios for polymerization water to dry matter and sodium silicate solution to NaOH solution were 0.4741 and 1.5, respectively, resulting in maximum compressive pressures of 3, 7, and 28 days.","PeriodicalId":31435,"journal":{"name":"International Journal of Innovation in Mechanical Engineering and Advanced Materials","volume":"27 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73981756","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}

In this study, we sought to investigate the upstream documents and statements of the Supreme Leader to enumerate the dimensions and components of National Powerness. The method used was based on documentary study and to analyze the findings, the Content Analysis method was used. In the policy section, upstream documents such as the constitution, the vision of the I.R. Iran on the horizon of 1404, the declaration of the second step of the Islamic Revolution of Iran and other documents were examined. In the speeches section, statements of the Supreme Leader among scientific experts, university professors, industry, and technology activists, etc. were reviewed and analyzed. The themes extracted from these documents were classified into six dimensions: political, defense-security, environmental, economic, scientific, technological, and cultural discourse. Below these dimensions, 75 components were extracted.

The age of the students ranged between 25 and 34 years. 55.2% were female and 54% were economically active. 40.9% had a work experience of less than a year. The academic degree of the majority of participants was master’s degree. 93.9% of the participants believed that big data analysis was essential for the country. 43.2% maintained that big data mostly belonged to the communication industry. 28.1% perceived MATLAB useful software for analysis. 40.9% were familiar with the benefits of analysis. Engage in economic activities, less than 1 year of experience and studies for a Master’s degree showed to be significantly correlated with familiarity with the benefits of big data (p≤0.01).
