Abstract

Bi-2212 superconductor has garnered significant interest in recent years due to its potential applications in the development of superconducting wires and tapes. The effect of introducing carbon nanotubes (CNT) into the Bi-2212 system was investigated in terms of superconducting and structural properties. The results of this study indicated that the addition of CNTs had a notable effect on the phase formation of Bi-2212,  with a substantial increase from 86.8% to 97.4% for the sample with a weight percentage of 0.8 wt.%.  This can be attributed to the improved particle orientation brought about by the introduction of CNTs.  The microstructure analysis displayed randomly distributed grains of irregular shapes, with a reduced average grain size of 1.018 μm upon the addition of 0.4 wt.% CNTs. Additionally, the inclusion of CNTs led to an increase in the Tc value, with the maximum Tc-onset recorded at 79 K for the sample containing 0.6 wt.% CNTs.  In summary CNT has enhanced the structural  and the superconducting properties of the Bi-2212 synthesised with thermal treatment method.

Abstract

This study aims to determine the effect of the project-based learning model on students' critical thinking skills on elasticity and Hooke's law. The population in this study was all class XI MIPA SMAN 1 Terara. Sampling was carried out using a purposive sampling technique, so that class XI MIPA 1 as many as 30 people as the experimental class and class XI MIPA 3 as many as 30 people as the control class. The type of research used was a quasi-experimental with a nonequivalent control group research design. The instrument used was a descriptive test of 5 questions. Post-test data were analyzed using a normality test using the chi-square formula and homogeneity test using a variance test, then hypothesis testing using a polled variance t-test, because the number of students in the experimental and control classes was the same and the data was distributed homogeneously. This test was conducted to determine whether or not there was an effect of the project-based learning model on students' critical thinking skills. Data analysis shows that the values are 5,90 and 2,00, so that  it means there is a positive influence of the project-based learning model on students' critical thinking skills in the material on elasticity and Hooke's law
