Abstract

Gelatin gel merupakan turunan dari protein yang diperoleh dari proses hidrolisis kolagen pada tulang dan kulit hewan vetebrata. Penelitian ini bertujuan untuk menentukan differensiasi dari gelatin kulit babi dan sapi. Penelitian ini menggunakan metode perendaman dengan larutan asam yaitu CH3COOH sebagai pembutan gelatin dari kulit babi dan sapi kemudian dikarakterisasi menggunakan Fourier Transform Infrared (FTIR) pada gugus Amida A, Amida I, Amida II dan Amida III selanjutnya daerah dari puncak spektrum dari hasil FTIR dianalisis menggunakan Principal Component Analysis (PCA) yang berupa pengelompokan pada kuadran I,II,III dan IV. Hasil PCA yang diperoleh yaitu dalam bentuk score plot menunjukkan bahwa gelatin dari kulit sapi terletak pada kuadran III sedangkan gelatin dari kulit babi terletak pada kuadran I. Kesimpulan penelitian ini ialah dari metode FTIR perbedaan dari gelatin kulit babi dan sapi ditunjukkan melalui dearah puncak spektra sedangkan dari metode PCA perbedaan antara kedua jenis gelatin dibedakan dari letak kuadran pada score plot.

Abstract

Penelitian ini mengeksplorasi peran analisis flash point dalam menilai kualitas Oil Turbolube. Flash point, sebagai indikator penting, digunakan untuk menentukan tingkat kestabilan dan kemampuan oli dalam menahan suhu tinggi sebelum terjadi penguapan cepat. Studi ini menguraikan pentingnya flash point dalam menilai performa dan keandalan Oil Turbolube dalam lingkungan suhu tinggi, mempertimbangkan dampaknya terhadap kinerja mesin dan sistem yang menggunakan oli ini. Metode analisis flash point sebagai alat evaluasi kualitas oli diperinci untuk mendukung pemahaman tentang cara optimal untuk menilai dan mempertahankan kinerja oli dalam aplikasi Turbolube. Dengan mendasarkan fokus pada parameter flash point, artikel ini memberikan wawasan yang berguna bagi industri dan pemeliharaan mesin terkait penggunaan Oil Turbolube yang efektif dan efisien. Kualitas dari oil Turbolube Pertamina XT 32 yang telah dianalisa memiliki range 241 sampai 249 dengan rata-rata 245,85. Dimana hasil ini memenuhi spesifikasi.

Abstract

Physics learning is a complex subject that required an extraordinary understanding. Based on the results of interviews at SMAN 4 DKI Jakarta, in Banda Aceh, critical thinking skill tests have not been carried out and student responsibility in following lessons.  This research aims to optimize physics learning through the PjBL-STEM model, in order to improve students' critical thinking skills and lack of sense responsible attitudes. The research design that used in this research was a one group Pretest and Post-Test Design, it was involving 120 students in grade XI. The data collection techniques are carried out through observation, interviews, questionnaires and tests that are prepared based on indicators of critical thinking skills. This research data was analyzed using the average test, N-gain and paired sample t-test. The instruments used critical thinking skills tests and responsibility attitude questionnaires. The research results show that the average N-gain 0,67 is categorized as currently. The results of the responsible attitude questionnaire are in the effective category with an average of 367.2, From the findings of this research it can be concluded that the PjBL-STEM model can optimize physics learning in improving critical thinking skills and attitudes of responsibility.

Abstract

Apart from the blessing of parents, there are some restrictions that couples who are about to get married should not do. One of them is the ban on marriage, namely from the Javanese community the prohibition on the marriage of the first child with the first child. The film Katresnan tells the story of the main character who experiences many problems in his life after getting married. Hayatri is a child of Hastomo, a person who is guided by primbon books which contain customs and habits that exist in Javanese society. Hayatri's expressions are emphasized in the direction of the fiction film Katresnan which aims to present Hayatri's emotions. The object of the creation of the film Katresnan is a scenario that tells of a girl named Hayatri who wants to marry a man of her choice, but her father doesn't approve because there are several things that become problems in the primbon book. Likewise, after getting married, Hayatri wanted to move house, but her father didn't approve because the house didn't suit their weton either.The aesthetic concept for the creation of the Katresnan film is in the emphasis on expression, presenting Hayatri's emotions by depicting facial expressions, voice, attitudes and gestures. The Katresnan film is embodied in a 23-minute film with a rich family drama genre with expressions to add to the attractiveness of the scene. Key words: Fiction film, directing, expression, emotion
