Development of Animation Video Media based on Inquiry Strategy for Mathematics Learning
No full textThis research is motivated by the low understanding of students in learning mathematics, especially in abstract material. This affects student learning outcomes which are still relatively low and have not reached the specified minimum completeness criteria (KKM). This study aims to produce instructional media in the form of inquiry strategy-based animated videos for mathematics learning in Senior High Schools (SMA) that are valid, practical, and effective so that they can assist teachers/educators in conveying material so that it is easier for students to understand. This research includes research and development (Research and Development). This study used the ADDIE development model with 5 stages, namely analysis, design, development, implementation, and evaluation. The instrument in this study used a questionnaire to test validity and practicality, and student learning outcomes of testing the effectiveness of the animated video media developed. The results of this research and development indicate that the validity test based on the media expert questionnaire validation for the first stage obtained an average value of 2.84 with good/quite valid criteria and the second stage obtained an average value of 3.92 with very good/valid criteria. While the validation of material experts for the first stage obtained an average value of 2.725 with good/quite valid criteria and the second stage obtained an average value of 3.78 with very good/valid criteria. The results of the practicality test based on the analysis of the mathematics teacher's response questionnaire for the first validator obtained an average value of 4.138 with good/practical enough criteria, while for the second validator an average value of 4.19 was obtained with good/quite valid criteria. The results of the practicality test based on the analysis of the response questionnaire from students of class XI MIA-1 SMA 1 Barumun Tengah obtained an average value of 4.48 with very good/practical criteria. In contrast, the questionnaire analysis of students' responses to class XI MIA-3 MAN 2 Padang Lawas obtained an average value -average 4.26 with very good/practical criteria. Whereas the results of the effectiveness test based on the percentage of classical learning completeness of students in class XI MIA-1 SMA 1 Barumun Tengah obtained an average value of 86% in the very good category, while the percentage of classical learning completeness of students in class XI MIA-3 MAN 2 Padang Lawas was obtained an average value of 88% with very good category

Role of Biotechnology in the Conservation of Plant Biodiversity
No full textBiological diversity provides the variety of life on the Earth and can be defined as the variability among and between the living organisms and species of surrounding ecosystems and ecological complexes of their life support. It has been estimated that one third of the global plant species are threatened in different level according to the International Union of Conservation of Nature (IUCN).The major threat to rapid loss and extinction of genetic diversity due to habitat destruction, pollution, climate change, invasion of exotic species, human population pressure, ever increasing agricultural pressure and practices, life style change etc. are well-known. Biodiversity conservation is a global concern. All member states of the Convention on Biological Diversity (CBD) took measure to preserve both native and agricultural biodiversity. The global concern of biodiversity conservation initiated either by in situ or ex situ methods. In situ methods protect both plants and their natural habitat. On the other hand, ex situ methods involves preservation and maintenance of plant species or plant parts (such as seeds, cuttings, rhizomes, tubers etc.) outside their natural habitat for the purpose of developing seed banks or more preciously gene banks following classical / advanced methods of plant propagation. Classical methods of plant propagations have certain limitations in terms of rapid production of plants or plant propagules and their long term conservation. So, the biotechnological methods such as plant tissue culture, plant cell culture, anther culture, embryo culture etc. are quite applicable and useful techniques for ex situ conservation. On the other hand, the production of superior quality seeds has enhanced by the application of plant biotechnology. So, plant biotechnology offers new means of improving biodiversity conservation rather than threatening biodiversity in various ways
