This reactor uses Thorium main fuel which is enriched with Uranium 233 so that the reactor can operate, and SCO2 (supercritical carbon dioxide) as cooled. The fuel combustion strategy uses the modified CANDLE principle. The composition of the fuel in the modified CANDLE method is divided into 10 fuel regions and 10 years of combustion cycle. After 10 years the burn-up process of fuel in the first region is transferred to the second region, the fuel in the second region is transferred to the third region, the fuel in the third region is transferred to the fourth region, and so on. Fuel in region 10 is then ejected. The first region is filled with new natural Thorium fuel. The process is repeated until equilibrium conditions are reached. From the simulation results of the calculations on the core design, the multiplication factor (K eff ) and the most optimal burn-up level are obtained.","PeriodicalId":210626,"journal":{"name":"Jurnal Penelitian Sains","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133639827","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 aims to design automatic pencil sharpener hardware and software based on the length of time needed to knit pencils according to pencil diameters based on ATmega 328 microcontrollers. The timing is based on the pencil brand and the thickness level of the pencil graphite which is 6H, 2H, F, 2B and 6B for a diameter of 1 mm to 7 mm. The larger the diameter of the pencil, the greater the time it takes to knit.

World researchers are actively seeking innovative solutions to tackle this issue. This article presents an overview of various synthesis methods for materials such as Fe 3 O 4 , SiO 2 , and TiO 2 , with the aim of addressing water pollution. By implementing strategies like coprecipitation, sol-gel, and hydrothermal techniques, these materials have successfully formed high-quality nanoparticles with controllable sizes and distributions. Several studies and characterizations demonstrate that the combination of Fe 3 O 4 /SiO 2 /TiO 2 can be used as a catalyst for degrading pollutants in water. Key factors, such as the appropriate choice of solvents, precise regulation of temperature, pressure, and careful time intervals, are crucial in making significant strides towards overcoming water pollution.","PeriodicalId":210626,"journal":{"name":"Jurnal Penelitian Sains","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126569731","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}
