Abstract

This research succeeded in creating a thin layer of SnO2 and SnO2: In+Al through a synthesis process with the sol-gel spin-coating technique on a glass substrate. The manufacture of this thin layer uses the basic material SnCl2.2H2O, and the doping material InCl3.4H2O and AlCl3. This thin layer is made with variations in doping concentration, number of layers, and heating temperature. The results of the synthesis of SnO2: In+Al films show that the thin film formed is more transparent when the doping concentration and the number of layers is increased. Meanwhile, the thin layer that forms is increasingly not transparent when heated at higher temperatures

Abstract

High-Temperature Gas Reactor (HTGR) is a type of reactor that continues to be developed because of its advantages in terms of economic aspects, proliferation resistance, and safety aspects. One of the safety aspect improvements is due to the use of the Coated Fuel Particle (CFP). A coated fuel particle is a fuel with a diameter smaller than 1 mm and is protected by several carbon layers. In the Pebble Bed Reactor (PBR) type of HTGR design, the CFP is placed in a 6 cm fuel ball. How much CFP is put into the fuel ball will determine the neutronic characteristics of the reactor. In this study, the effect of the amount of CFP in the fuel ball on the 25 MWt PBR design using Thorium fuel and its impact on several important neutronic aspects, such as the effective multiplication factor, the amount of fuel enrichment, the utilization of fissile material, and the density of the fissile material formed. The calculation was performed by the Monte Carlo MVP / MVP-BURN code. This study found that the coated fuel particle fraction of 15% was the optimum value for the studied neutronic parameters.

Abstract

This study aims to develop scientific science attitudes assessment instruments that can be used in elementary school-based values of character education. This research is a research development (R & D) conducted for one year with preliminary study stage, product development, product trial and product dissemination developed. A preliminary study was conducted by surveying the implementation of the science assessment in primary school. The preliminary study results show that teachers in 10 surveyed schools have never implemented a scientific attitude assessment in science learning. At the stage of product development, has developed a scientific attitude assessment instrument that has been validated by experts. The product trials were conducted in three stages: initial field test, main field test and field operational test. In the initial field test, it was conducted in two schools with 20 respondents in each class. Initial field test results show that the instrument reliability level is good, but there are still some invalid items that are 11 items in class IV, 8 items in class V and 7 items in class VI. This is because there are still some respondents who have not read smoothly so that they have difficulty in answering questions. In the main field test, it was conducted in 8 schools with 91 respondents. The main field test result is that there are 5 invalid questions, both in class IV, V and VI. Operational field tests were carried out with the number of respondents each 13 students from 10 schools. Field operational test results are all items declared valid and reliable. The last stage is to disseminate products through scientific forums such as seminars and socialization to schools. The scientific attitude instruments developed in this study can be used by elementary teachers to assess the scientific attitudes of elementary students.
