Abstract

The background of this research is because the Prezi application-based KOH Link learning media has not yet been developed in science learning. In the learning process, the teacher already uses learning media but is less creative, while at school the facilities and infrastructure are adequate, such as LCD projectors. This study aims to determine the process of developing prezi-based KOH Link learning media products, to determine the level of effectiveness of learning media. This type of research is research and development (research and development) of the Four-D model which consists of defining, designing, developing, and disseminating. Data collection techniques are carried out by carrying out effectiveness. Data analysis techniques are performed by calculating the average value of the results of effectiveness. The results showed that classical completeness was 81.48% with very good criteria and student responses obtained an average of 3.7 with very positive criteria. Thus, it can be concluded that the Prezi-based KOH Link learning media in classifying animals based on the type of food is very effective as one of the media in science subjects.

Abstract

The development of teaching materials such as digital-based supplementary books really needs to be done considering that COVID-19 has not yet been integrated with biology subjects. Students need to dig up information about COVID-19 through scientific literacy and solve problems through critical thinking. This study aims to determine the effectiveness of digital-based supplement books through quasi-experiments by looking at the comparison of pre-test and post-test results. The data were analyzed quantitatively to determine the category of effectiveness and deepened by a qualitative analysis of the influencing factors. Sig. The value of (2-tailed) Paired T-test is 0.000. which shows that there is a difference in the average learning outcomes before and after using the supplement book. This means that the COVID-19 prevention supplement books greatly affect students' scientific literacy skills and critical thinking skills. Scientific literacy is enhanced because the content in the book explores COVID-19 information and is integrated into the material. Meanwhile, critical thinking is empowered with direction analysis and decision making in books. The book developed is predicted to be very useful and supportive in learning biology, especially relevant material such as material about viruses, the respiratory system, and the immune system

Abstract

Biofuel is an alternative energy to replace fossil fuels. The most popular form of biofuel today is bioethanol. Biofuels are considered as a suitable alternative to fossil fuels because they are more environmentally friendly. Production of bioethanol utilizing thermophilic microorganisms is more profitable because thermophilic microbes generally have the characteristics of being able to use a variety of substrates, low contamination, and resistance to high temperatures. The use of microbial consortia tends to give better results than the use of monoculture isolates to optimize bioethanol yields. The aim of this study was to determine the compatibility and ability of the best thermophilic bacterial triculture consortium from the Mudiak Sapan hot springs in producing biofuel. This research is a descriptive research, to test isolates of a consortium of thermophilic bacteria that produce bioethanol. The results of this study showed that consortium isolates tended to give better results than monoculture isolates. The best thermophilic bacterial triculture consortium from the Mudiak Sapan hot springs in producing biofuels namely MS 12, 17, 18 produced a bioethanol content of 0.863%.
