Abstract

Tujuan penelitian adalah untuk mengetahui bagaimana Model Pembelajaran Kooperatif Tipe Scramble di SMA Negeri 1 Tondano mempengaruhi hasil belajar biologi siswa. Penelitian ini dilaksanakan di kelas X SMA Negeri 1 Tondano pada tahun ajaran 2023–2024. Sampel penelitian terdiri dari 26 siswa kelas X-4 dan 25 siswa kelas X-3. Dengan nilai t tabel sebesar 1,676 maka nilai t hitung sebesar 4,847 sesuai dengan data pengujian hipotesis uji t. Selanjutnya, n1+n2-2 (25+26–2) = 49 derajat kebebasan digunakan, dan ambang batas signifikansi ditetapkan sebesar 0,05. Hal ini dapat ditentukan dengan membandingkan nilai thitung dan ttabel yaitu thitung > ttabel, maka H0 ditolak dan H1 disetujui. Oleh karena itu, dapat dikatakan bahwa model pembelajaran koperatif tipe scrambel berpengaruh terhadap hasil belajar siswa pada pembelajaran biologi.

Abstract

Tilapia is a freshwater animal that is always in contact with the aquatic environment so that it is easily infected by bacteria through water. This study aims to identify the types of bacteria that cause diseases that attack Tilapia (Oreochromis niloticus) kept in Dimembe District, North Minahasa Regency. This study uses a descriptive exploratory research method. The results of the study found sixteen isolates and identified them as bacteria that cause Tilapia disease in North Minahasa Regency, including Aeromonas sp. (4 isolates), Plesiomonas sp. (5 isolates), and Enterobacter sp. (1 isolate). based on morphological characteristics (colonies and bacterial cells) and biochemical (catalase, oxidase and motility tests). It was found that periodic and continuous fish disease surveillance is needed to monitor the spread of fish diseases, especially Tilapia disease in North Minahasa

Abstract

The Pancasila Student Profile Strengthening Project or often referred to as the P5 Project is an effort to support the realization of student figures based on the Pancasila foundation through the process of reviewing student learning materials based on projects. One of the topics of the P5 activities carried out at SMA N 2 Ratahan is entrepreneurship, and coconut oil processing is the theme raised. The implementation method of community service activities consists of dissemination, training/technology transfer, as well as monitoring and evaluation at the final stage. Through this community service activity, there is an increase in the level of community empowerment in this case students and teachers, namely increasing student knowledge and skills about processing coconuts into coconut oil and blondo using more modern tools. The activities include production and packaging. This activity has also been able to improve students' life skills to be able to become entrepreneurs later.

Abstract

This study used catfish Clarias gariepinus as an experimental animal, which given supplementation of curcumin and thyroxine hormone. The results showed that during the reproductive period there was an increase in body weight of female catfish in line with the development of the gonads. Through the histology of the gonads, it appeared that oocyte development occurs over time.  The results of liver histology showed a high activity of hepatocyte cells as indicated by the formation of vacuoles, as the storage site for vitellogenin, in their cytoplasm. Supplementation of curcumin and thyroxine was able to increase the specific growth rate of catfish, and the catfish group that given the combination treatment of curcumin supplementation (5 g.kg-1 of feed) with thyroxine hormone (0.1 mg.kg-1 of feed) showed the more optimal results.

Abstract

This research is motivated by the occurrence of various difficulties in the learning process, namely teachers have not used a variety of learning methods according to students' learning styles so that students' interest in learning is still lacking. This research is a qualitative descriptive study. Data collection techniques using questionnaires, interviews and documentation. The data sources in the study were outstanding biology students in class XI. The sources in the study were 3 outstanding students who obtained the highest scores in Biology subjects in Class XI A-XI G of SMA Negeri 3 Manado. Based on the data obtained through research and data validity tests using data triangulation, it can be concluded from the results of the study which show that outstanding students in Biology subjects in Class XI A-XI G of SMA Negeri 3 Manado have a combined learning style of visual, auditory and kinesthetic (VAK). However, among these learning styles, the most dominant is the kinesthetic learning style, from 21 students it was found that 3 students had a tendency towards a visual learning style, 5 students had a tendency towards an auditory learning style, 10 students had a tendency towards a kinesthetic learning style and 3 students had a combination of learning styles, namely: 1 student had a visual kinesthetic learning style, 1 student had an auditory kinesthetic learning style, and 1 student had a visual, auditory and kinesthetic learning style.
