This study aims to determine the effect of sodium sulfate (Na2SO4) addition on the reduction proses of tiania iron sand. The sample that used in this research are the iron sand that taken from Sukabumi, West Java, coal as reductor, sodium carbonate (Na2CO3), and sodium sulfate (Na2SO4) as additive and primary parameter. From the result of XRD characterization and semi-quantitative analysis the addition of sodium carbonate (Na2CO3) on roasting process remove the impurities like alumuniom oxide (Al2O3). In the other hand, the content of titano-magnetite (Fe2TiO4-Fe3O4) in the iron sand increase with addition of sodium sulfate (Na2SO4). Meanwhile, from semi-quantitative analysis result with the variation of sodium sulfate (Na2SO4) in 5%, 15%, and 25% have an optimum point on the addition of 15% sodium sulfate (Na2SO4) with 46,9% of titano-magnetite (Fe2TiO4-Fe3O4) content.
Cybersecurity is currently being used by government organizations in protecting their resources such as data and assets as well as avoiding catastrophic pollution and the failure of key infrastructure that can harm human health and environment. The increasingly modus operandi of modern drug crime syndicates which utilizing technology to attack the network of the National Narcotics Board (NNB) is a threat and vulnerability for NNB, so NNB must make efforts to mitigate the risk. Research on the implementation of cybersecurity projects at the National Narcotics Board aims to explore information related to the implementation of cybersecurity projects in securing and defending data and information networks at NNB. The research method used is a descriptive approach with qualitative methods through semi-structured interviews and observation. This cybersecurity project provides benefits for data and information protection at NNB, through a cybersecurity monitoring system assisting NNB in monitoring cyber traffic conditions in real-time. From this study, it was found that the factors influencing the implementation of cybersecurity projects that were mapped to critical success factors for information technology projects, namely involvement and effective communication, capability and motivation of the team, capability, and leadership of the project manager, requirements management, clear project objectives, and top-level management support levels.
Indonesia has rich deposit of Iron Sand that can be found along of the Java southern part island. Iron sand contains some Ti-Rich minerals such as ilmenite, titanomagnetite dan rutile. This study aims to determine the effect of time variation on the results of Increasing titanomagnetite in iron sand and addition of 15% Na2SO4 as a catalyst. Variation of this reasearch was respectively 10 minutes, 20 minutes and 30 minutes with reduction temperature at 800 O C. It takes the stage of roasting to condition the ore to be more easily reduced and increase the metal content so that it can maximize the iron sand purity with addition of Na2CO3 additive with mass ratio 1:0.4 . Based on the XRD and Semi-Quant equation using Software HighScore Plus, optimal time for reducing iron sand with coal at 800 O C is 30 minutes, which produce content of titanomagnetite as much as 36%.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
