Pengembangan Media Video Animasi dengan Kinemaster untuk Pembelajaran Fisika pada Topik Gerak Parabola Kelas X SMA
Get PDFJenis penelitian ini menggunakan penelitian dan pengembangan (R & D). Objek penelitian ini adalah video animasi berbasis aplikasi kinemaster dalam pembelajaran fisika pada materi gerak parabola. Penelitian pengembangan media video animasi menggunakan aplikasi kinemaster ini bertujuan untuk mengetahui kelayakan dari media pembelajaran fisika pada topik gerak parabola di SMAN 2 Donggo. Intrumen pengumpulan data yang digunakan berupa validasi ahli materi, lembar validasi ahli media, dan angket resspon peserta didik. Teknik analisis data yang digunakan adalah dengan cara menganalisis skor persentase penilaian validasi. Hasil penelitian menunjukkan bahwa yang didapatkan dari validasi memenuhi kategori sangat layak dari ahli materi dengan rata-rata 9,75%, ahli media sebesar 90,22%. Adapun hasil angket respon peserta didik setelah dilakukan validasi terhadap video animasi oleh para ahli, hasil penilaian dari responden dengan rata-rata 79,5%. Berdasarkan hasil perolehan tersebut, dapat disimpulkan bahwa media pembelajaran video animasi dengan kinemaster sangat valid digunakan sebagai mediia pembelajaran fisika pada topik gerak parabola
Morphology and selected properties of cellulose acetate membranes for environmental applications
Get PDFMicroporous membranes were obtained by dry-wet phase inversion from a solution of cellulose acetate (CA) in acetone (13, 14 and 15 wt%). Polyethylene glycol was used as a blowing agent. The structure and mechanical properties were examined. FT-IR spectra show that the addition of polyethylene glycol improves the thermodynamics of the solution and increases the hydrophilicity of the membrane. The SEM method confirmed the microporous structure of membranes with an asymmetric structure and various pore sizes and porosities. Higher CA concentration resulted in better tensile properties
Human Behavior in Social Context
Get PDFHumans are complex social beings, and their behavior is influenced by interactions with their social environment. In this context, a deep understanding of the factors that shape human behavior is essential. This research aims to understand how cultural values, norms, and traditions influence human behavior in a particular social context. This research uses the case study method. Research subjects may include diverse groups of people involved in social interactions, such as individuals from different age groups, cultures, and socio-economic backgrounds. Data collection techniques include participant observation and case studies. The results show that human behavior in social contexts is strongly influenced by various factors, including culture, norms, and interactions between individuals. Data analysis confirmed that culture plays an important role in shaping behavior, with cultural values influencing individual decisions and actions
