Abstract

This research have goals to determine the increase in student learning outcomes using STEAM learning is better than improving student learning outcomes using direct instructions in Electrochemistry Before treatment, 25 pretest questions were given . Then given a different treatment, the experimental class studied using STEAM learning and the control class studied with direct instructions. After the treatment given a post-test. In the pretest, the experimental class average was 40.11 and in the control class was 39.11. In the post-test, the experimental class was 83 and the control class was 75.40. The effectiveness of STEAM learning is 25% compared to Direct Instructions. The conclusion of this research is learning outcomes using STEAM learning are better than Direct Instructions. The difference in student learning outcomes using STEAM with student learning outcomes using the lecture method is 19%.

Abstract

Ulat sagu memiliki nama yang beragam dan paling sering ditemui di daerah Kalimantan, Sulawesi, Papua dan Sumatera yang diperoleh dari batang pohon sagu yang telah tumbang dan sudah membusuk. Tujuan penelitian untuk mengetahui protein ulat sagu dengan metode Kjedhal, Spektro fotometer dan SDS-PAGE. Jenis penelitian dengan melakukan kajian literature dari buku, artikel dan jurnal sepuluh tahun terakhir dari google scholer. Hasil analisis menggunakan metode Kjedhal pada batang berduri sebesar 11,8652% yang tidak berduri sebesar 10,06988%. Penelitian lainnya yang dilakukan di hal mehera maluku utara kadar protein total sebesar 4,0575%. Hasil analisis menggunakan metode spektro fotometri dan SDS dengan pengeringan garam dan tanpa garam menunjukkan ulat sagu control memiliki protein yang lebih besar (4,93 µg/µl) daripada yang diberi perlakukan dan penggaraman konsentrasi 10% (b/b) selama 1 jam tanpa panas pita-pita protein tidak terjadi penurunan atau penipisan secara signifikan. Analisis Pengasapan dengan garam dan tanpa garam menunjukan ulat sagu control lebihbesar (4,93 µg/µl) dibandingkan dengan yang diberi perlakuan dan semakin lama waktu pengasapan maka semakin banyak pita protein yang terdenaturasi dengan berat molekul yang semakin kecil. Pengaruh penggaraman konsentrasi 10 % b/b dan pengasapan terhadap jumlah profil protein ulat sagu cenderung lebih besar dibandingkan pegaruh pengasapan saja.

Abstract

This research is supposed to develop generic science skill-based student worksheets on chemistry learning materials acid and based. The method used in this research is the following ADDIE models (Analysis, Design, Develop, Implementation, and Evaluation). In the implementation step, the worksheet was used on 11th grade of South Tangerang Banten, Indonesia, general high school which was followed by 29 students. The instrument used is a questionnaire to measure the feasibility of the worksheet by experts (lecturer and teacher), and also student questionnaire response sheets. The findings of this research can conclude that the feasibility in terms of design component, appearance, content, language, and worksheet's appropriate with generic science skills. And the student responses, respectively for 84.13%; 92.26%; 92.41%; 95.95%; and 86.9%. This result shows that generic science skill-based worksheets can be used for the learning process. But still need to develop for bigger responders.

Abstract

This research is motivated by students' learning motivation which is still in the low category. Giving reward and punishment to students aims to motivate students so that they learn better. This study aims to determine whether there is an effect of reward and punishment on students' learning motivation in stoichiometry material. The subjects of this study were 10th grade students at public high school at Pekanbaru City, Indonesia. This study using a purposive sampling technique with consideration of classes having low learning motivation and obtained first class as an experimental class and second class as a control. Data collection techniques used are questionnaires, observation, and documentation. Final data analysis in this study using the t test. From the results obtained, the value of t-count = -3.720 and t-table = 2.04 at a significant level of 5% and Sig. (2-tailed) of 0.001. From this study it was concluded that t-count t-table and Sig. (2–tailed) 0.05. So the null hypothesis (H0) is rejected and Ha is accepted. This means that there is a significant effect of reward and punishment on student motivation in stoichiometric material with an effect coefficient of 10.12%.
