This study aims to develop and obtain eligible online learning media by using moodle for general chemistry subjects by using moodle. In this study, flash animation and simulation were integrated as online media in moodle to attract students’ motivation. The topic in this moodle was a colloidal solution. The method of this study was the research and development method by using ADDIE model. Online learning media was validated by media and chemistry material experts, then the valid media presented to the 24 chemistry education students in Universitas Islam Riau to acquire responses toward online learning media. The results showed that online learning media is eligible and can be used as online learning media in which the average number of expert assessment reached higher than 80% with valid criteria. In addition, students’ responses toward online learning media by using moodle is positive in all aspects (interesting design; color, picture, and video preference; creativity and innovation; communication) with the average number of percentage more than 84% (good criteria). Overall, based on the results of online learning media by using moodle for general chemistry subject can be used as learning media to give students experience in online learning
Penelitian ini bertujuan untuk mengembangkan instrumen literasi digital sekolah, guru dan siswa yang berfungsiuntuk mengukur sejauh mana tingkat literasi digital sekolah, guru, dan siswa. Tidak mungkin suatu sekolah dapat mengikuti perkembangan IPTEK jika potensi sekolah tidak memadai dan sumber daya manusianya belum siap. Oleh karena itu, pengembangan instrument literasi digital perlu dibuat agar dapat mengidentifikasi tingkat kesiapan sekolah, guru dan siswa dalam menghadapi era digital di revolusi industri 4.0. Subjek penelitian yaitu 120 responden yang terdiri dari 30 orang pimpinan beserta guru dan 60 orang siswa yang terdiri 30 laki-laki dan perempuan di SMA Negeri 14 Pekanbaru. Angket yang telah dibuat terlebih dahulu divalidasi oleh 2 validator ahli, setelah dinyatakan valid oleh validator ahli selanjutnya angket dilakukan uji terbatas untuk menghitung tingkat validitas dan realiabilitas masing-masing item pertanyaan. Angket menggunakan skala likert dengan 3 kategori pilihan jawaban (sering, jarang, tidak pernah atau ada, sedang direncanakan, tidak, dsb). Berdasarkan hasil dan kesimpulan dapat ditarik kesimpulan yaitu: butir soal yang dapat dijadikan sebagai alat pengumpul data pada instrumen angket literasi digital sekolah yaitu sebanyak 23 butir pertanyaan, sedangkan butir soal yang dapat dijadikan sebagai alat pengumpul data pada instrumen angket literasi digital guru 52 butir pertanyaan dan instrumen angket literasi digital siswa sebanyak 31 butir pertanyaan. Berdasarkan kriteria reliabilitas, ketiga angket literasi digital menunjukkan kriteria reliabilitas tinggi dan sangat tinggi dengan tingkat reliabilitas lebih besar dari 0,684.
This research examined the quality of edible oil from Crude Coconut Oil (CCO) and Palm Coconut Oil (PCO) and their blends with CCO : PCO proportional was about 40:60 and 60:40, respectively. The quality of these samples was based on water proportion, free fatty acid (FFA) and peroxide value (PV) contained. This study was conducted to improve the quality of edible oil. SNI 3741-2013 was used as method of this research, which the result compared with the SNI standard for edible oil. Results of this research for water proportion in oil samples PCO, CCO, CCO (40) : PCO (60) and CCO (60):PCO (40) in order were 0.000122; 0.010905; 0.001878; 0.030996. The FFA proportions for them were 0.02; 0.01; 0.02; 0.02 and PV values were 7.10; 3.00; 6.10; 5.10, respectively. From this result, we can conclude that all samples had good quality for water proportion and FFA, except for peroxide value (PV) mark which had the higher mark compared to the SNI standard. We also concluded that CCO became the best quality of edible oil compared to others.
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.
