Penerapan Model Pembelajaran Problem Solving Untuk Meningkatkan Penguasaan Materi Kalor Dan Perpindahan Pada Peserta Didik Kelas VII SMP 6 Inamosol Kabupaten Seram Bagian Barat
Get PDFThis study aims to determine how applying problem-solving-based learning models improves the understanding of mastery of heat and its transfer material in 7th-grade students of SMP 6 Inamosol, West Seram Regency. This type of research is quantitative descriptive research with a one-group pretest-posttest design. This research data was analyzed based on acquiring initial and final test scores and increasing mastery of material using the average normalized gain. The data analysis showed that all students' initial material mastery ability was in the failed qualification (100%), with an average score of 21,19. This situation shows the low ability of students' initial knowledge of heat and transfer material. After applying the problem-solving learning model, students obtained an average final test score of 85.08 with good qualifications. The average value of the N-Gain test results obtained 0,82 is in high qualification. Thus, applying the problem-solving learning model can improve the knowledge of 7th-grade students of SMP Negeri 6 Inamosol, West Seram Regency, on the material of heat and its transfer

Get PDFTiO2/CuO nanocomposite has been successfully synthesized using Wedelia trilobata (L.) leaf extract with TiCl3 and Cu(NO3)2 3H2O as precursors. The material formed was then characterized by scanning electron microscopy (SEM) to determine the shape and size and then energy dispersive X-ray (EDX) characterization to determine the atomic composition contained in this nanocomposite material. The results of SEM and EDX show that the material is spherical in shape and has an average size of 42 nm. The composition of TiO2 is 73.38% and CuO is 4.32%. Furthermore, the sample is characterized by X-ray diffraction (XRD) in which the diffraction peaks are at angles of 2 theta, 25.646° and 47.511° indicating TiO2 nanoparticle. Meanwhile, peaks are at 38.367° and 74.379° indicate CuO nanoparticle. Determination of the energy band gap of the material using the results of ultraviolet visible (UV-Vis) is 3.5 eV. Measurement of magnetic properties using VSM equipment. Based on the hysteresis curve, the TiO2/CuO nanocomposite material has diamagnetic properties and is a soft magnet material
