Abstract

Penelitian ini bertujuan untuk mengisolasi bakteri endofit dari daun dan kulit batang tanaman Laban (Vitex pubescens Vahl) dan uji antibakteri . Bakteri di isolasi menggunakan media HVA. Karakteristik bakteri endofit  diamati secara makroskopis, mikroskopis dan melakukan uji katalase serta untuk uji antibakteri menggunakan bakteri patogen Erwinia carotrova. Jumlah isolat endofit yang berhasil diisolasi berjumlah 8 isolat (4 isolat dari daun Laban dan 4 isolat dari kulit batang Laban). Karakterisasi dilakukan pada 8 isolat endofit yang dihasilkan bahwa isolat memiliki ciri-ciri yang berbeda baik secara makroskopis, mikroskopis, dan semua isolat endofit dari tanaman Laban menghasilkan enzim katalase (uji +). Uji Bakteri endofit  terhadap bakteri patogen diperoleh 7 isolat memiliki daya hambat terhadap bakteri Erwinia carotrova.

Abstract

The study of genetics and evolution emphasizes the problem solving and processes that require critical thinking skills. For this reason, a college student experimental worksheet (CSEW) based on critical thinking skills is needed, so that students can be more active and have a meaningful learning experience. The purpose of this research is to develop the CSEW based on critical thinking skills which will be used at the Course Genetics and Evolution. This research was conducted at the Biology Education Campus, Faculty of Teacher Training and Education (FTTE), Universitas Riau. The research starts in the odd semester 2020-2021 from September 2020 to January 2021. The process of development referred to the ADDIE model. The results showed that the overall validation of the CSEW is 3.52 or very valid categories and based on the limited scale trials is 3.50 or very good categories. While the average student critical thinking is 79.00 or in a good category. Thus, it can be concluded that the CSEW is possible to be applied in genetics and evolution courses.

Abstract

Writing this article aims to improve students' digital literacy by using interactive multimedia in science learning, focusing on the structure and function of plant tissue at MTsN 3 Rokan Hulu. This study consisted of two meetings using innovative technology in the form of interactive multimedia with different sub-materials, namely (1) the structure and function of plant tissues in roots, stems and leaves, (2) the structure and function of plant tissues in flowers, fruits and seeds. Aspects of digital literacy that will be assessed in this study include: accessing, analyzing and evaluating, creating, reflecting, and communicating. This research is a qualitative research with descriptive method. Samples were taken by simple random sampling technique. The sample is class VIII students at MTsN 3 Rokan Hulu as many as 32 students. The results showed that learning science on the structure and function of plant tissue by using interactive multimedia could improve the digital literacy of junior high school students with an overall percentage difference of 4.00% from meeting 1 (70.33%) to meeting 2 (74.33%). . Thus, it can be concluded that the use of interactive multimedia can improve the digital literacy of students at MTsN 3 Rokan Hulu in terms of the structure and function of plant tissues. In the end, it is hoped that similar research can be carried out related to efforts to increase digital literacy with other materials.

Abstract

The purpose of this study was to determine the effectiveness of using macromedia flash in the distance lectures for students of the Biology Education Study Program, FKIP University of Riau in 2021. This media application was applied to learning low-level plant systematics (STR) courses. The research was conducted at the Biology Education Study Program, FKIP Riau University, in the even semester of 2021. The object of the research was 35 students of Class A lectures on low-level plant systematics. The research was conducted using the classroom action method, namely applying macromedia flash learning media. The lecture period is divided into 2 rounds where the first round is learning without using macromedia flash media and the second round using macromedia flash. The indicators set in the form of student learning outcomes during lectures and student responses to the use of macromedia flash. The conclusion of the study is that the use of macromedia flash can improve student learning outcomes with an effectiveness ratio of 83% and is considered effective in terms of learning outcomes. Student responses to the application of macromedia flash media are classified as good with a percentage of 79.91%. Key words: Macromedia flash, Low Plant Systematics, Effectiveness   Abstrak. Tujuan dari penelitian ini adalah untuk mengetahui efektivitas Penggunaan macromedia flash pada perkuliahan jarak jauh mahasiswa Program Studi Pendidikan biologi FKIP Univeristas Riau tahun 2021. Aplikasi media ini diterapkan pada pembelajaran mata kuliah sistematika tumbuhan tingkat rendah (STR). Penelitian dilakukan di program studi pendidikan biologi FKIP Universitas Riau pada semester genap tahun 2021. Objek penelitian adalah mahasiswa Kelas A oerkuliahan sistematika tumbuhan tingkat rendah sebanyak 35 orang.
