Abstract

This study aims to develop snakes and ladders media, which is integrated in English to determine the level of attractiveness and feasibility of using it, and to find out the response of students after using the snake and ladder media integrated with English. The research method adapts to the development model developed by (Borg and Gall, 1989). The study used the following seven steps: (1) potential problems, (2) data collection, (3) product design, (4) product validation, (5) product revision, (6) product trial, (7) product revision. The data collection tools used are: material expert questionnaires and media expert questionnaires as well as educator response questionnaires to determine product feasibility, student response questionnaires are used to determine product attractiveness. The results of the research that have been developed obtained a design in the form of a snake and ladder media integrated with English in classroom learning, obtaining a feasibility percentage of 4.2 by material experts, 3.9 by media experts, and 4.4 by educators. The percentage of participants' responses to the attractiveness of the product obtained 6.6. Based on the results of the description above, the product developed by the researcher is feasible to be used as a learning medium.

Abstract

Validasi perhitungan kekritisan pada Gas Cooled Fast Reactor (GFR) menggunakan kode OpenMC dan SRAC telah dilakukan. OpenMC merupakan kode analisis neutronik yang bersifat open source dan probabilistik yang sedang dikembangkan oleh MIT hingga sekarang. Validasi kode OpenMC perlu dilakukan untuk menunjukkan hasil validitas perhitungan OpenMC dibandingkan dengan kode lainnya. OpenMC yang bersifat probabilistik, mensimulasikan random sampling partikel yang berjumlah besar. Hal terseut bertujuan untuk menunjukkan akurasi perhitungan OpenMC dengan menggunakan partikel yang berjumlah kecil. Validasi dilakukan dengan melihat selisih perhitungan nilai  dari kode OpenMC dan SRAC. Nilai konvergensi yang dihasilkan dari kode OpenMC dan SRAC dikatakan tervalidasi dengan memiliki nilai error <1%. Pada penelitian ini menggunakan 50.000 partikel dengan total pengulangan 100 batch aktif dan 30 batch tidak aktif yang disimulasikan. Hasil perbandingan menunjukkan bahwa OpenMC memiliki error maksimal 0,06% terhadap hasil perhitungan kode SRAC

Abstract

Comprehensive information about nuclear reactor coolant materials for application in heat-transfer systems is very important. One important physical property that needs to be known is the thermal conductivity. The goal of this work is to predict the thermal conductivity value of the liquid lead, which is one of the important candidates for cooling materials for Gen-IV fast nuclear reactor designs. The thermal conductivity of liquid lead in this study was predicted using the Green-Kubo scheme and the molecular dynamics (MD) computational method to collect the simulation data. The MD simulation was done in the NVT ensemble, using the Lennard-Jones interaction potential. We observe the thermal conductivity of the liquid lead can be studied based on the diffusion physical process. The thermal conductivity of the liquid lead obtained from this research is λ = 0.0113T + 8.8539 [W/mK]. As a conclusion, this result is very suitable, compared with the available experimental data, then the Green-Kubo method can be used to calculate the thermal conductivity of liquid metal as lead.
