Penelitian tentang Pengaruh Media Pembelajaran Berbasis Teknologi Informasi dan Komunikasi Terhadap Motivasi Belajar. Penelitian ini dilakukan terhadap peserta didik kelas sepuluh pada mata pelajaran ekonomi. Penelitian ini dilakukan untuk mengetahui pengaruh penggunaan media pembelajaran berbasis Teknologi Informasi dan Komunikasi terhadap motivasi belajar peserta didik. Penelitian ini adalah kuasi eksperimen dengan bentuk nonequivalent control group design. Berdasarkan uji normalitas, homogenitas, dan uji t dari data pretes-postes motivasi belajar peserta didik kelas eksperimen dapat disimpulkan bahwapertamaterdapat perbedaan motivasi belajar peserta didik antara sebelum dan sesudah perlakuan pada kelas eksperimen yang menggunakan media pembelajaran berbasis TIK. Kedua, terdapat perbedaan motivasi belajar peserta didik antara sebelum dan sesudah perlakuan pada kelas kontrol yang menggunakan media grafis. Ketiga, tidak terdapat perbedaan peningkatan motivasi belajar peserta didik antara kelas eksperimen yang menggunakan media pembelajaran berbasis TIK dengan kelas kontrol yang menggunakan media grafis.
School Physics Laboratory Management is one of the subjects in Physics Education Study Program on FMIPA UNJ which aims to build the competence of school laboratory management for physics education students. It have been developed integrated teaching materials consisting of syllabus, One Semester (RPS) Plan, hand out, Student Activity Sheet, and Student Performance Appraisal Sheet for Laboratory Administration Competence. The development model referred to is ADDIE. Has been validation with college Lecturer Physics Education Studies Program FMIPA UNJ, with the focus of validation of syllabus and OneSemester Lecture Plan (RPS). The recommendation of peers is the use of the tools developed in the lecture process. One Semester (RPS), hand out, Student Activity Sheet, and Student Performance Appraisal Sheet have been tested against the students. Student responses to lectures were collected using a questionnaire consisting of four pieces of grain. Students appreciate 84,59, meaning very good. The effectiveness of the use of lecture tools in building student competence is very high, which obtained an average score of 91.65 very good category. The results of the experiments show that the lecture tools developed are suitable for use as teaching materials.Keywords: integrated lecturing tools, student competence, laboratory management. AbstrakManajemen Laboratorium Fisika Sekolah merupakan salah satu mata kuliah pada Program Studi Pendidikan Fisika FMIPA UNJ yang bertujuan membangun kompetensi pengelolaan laboratorium sekolah bagi mahasiswa pendidikan fisika. Telah dikembangkan bahan ajar terpadu yang terdiri dari silabus, Rencana Perkuliahan Satu Semester (RPS), hand out,Lembar kegiatan Mahasiswa, dan Lembar Penilaian Kinerja Mahasiswa untuk kompetensi Administrasi Laboratorium. Model pengembangan yang diacu adalah ADDIE. Telah dilakukan validasi sejawat dengan Dosen Program Studi Pendidikan Fisika FMIPA UNJ, dengan focus validasi silabus dan Rencana Perkuliahan Satu Semester (RPS). Rekomendaso teman sejawat adalah penggunaan perangkat yang dikembangkan dalam proses perkuliahan. Rencana Perkuliahan Satu Semester (RPS), hand out,Lembar kegiatan Mahasiswa, dan Lembar Penilaian Kinerja Mahasiswa telah diujicoba terhadap mahasiswa. Respon mahasiswa terhadap perangkat perkuliahan dikumpulkan menggunakan angket yang terdiri dari empatbelah butir. Mahasiswa memberikan apresiasi 84,59, artinya sangat baik. Efektivitas penggunaan perangkat perkuliahan dalam membangun kompetensi mahasiswa sangat tinggi, dimana diperoleh skor rerata sebesar 91,65 kategori sangat baik. Hasil ujicoba menunjukan bahwa perangkat perkuliahan yang dikembangkan layak digunakan sebagai bahan ajar.Kata-kata Kunci: perangkat perkuliahan terpadu, kompetensi mahasiswa, pengelolaan laboratorium.
High-temperature oxidation is a serious problem for several materials during their application in aggressive environments, such as high temperatures, high-speed machining, and corrosive environments. This research was conducted to analyze the effect of high-temperature oxidation on the surface morphology of the Ni-AlN-TiN/Si3N4 composite coating. The coatings were electrodeposited at a current of 5 me for 15 minutes and various electrodeposition temperatures of 35°C, 40°C, and 45°C. This composite coating was formed on tungsten carbide substrates with the electrolyte solution consisting of 6 g/L AlN, 6 g/L TiN, 40 g/L H3BO3, 0.6 g/L Si3N4, 0.17 M NiCl2.6H2O, 0.38 M NiSO4.6H2O, and 0.6 g/L Sodium Dodecyl Sulfate. The high-temperature oxidation process was carried out at a temperature of 700°C for 2 hours in the furnace. The surface morphology was characterized by using Scanning Electron Microscopy (SEM). The results showed that the surface morphology of the Ni-AlN-TiN/Si3N4 composite coating deposited at a temperature of 40°C had a scaled growth, reduced cracks, and reduced pore. It was due to the effect of high-temperature treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
