Xylanase is an important enzyme for xylan degradation into xylan derivative compounds such as xylose, xylobiose, xylotriose and other oligoxylan. Xylan derivatives can be bioconverted into bioenergy (ethanol), food ingredients as well as pharmaceutical or nutraceutical goods. Some bacteria have been reported to produce xylanases using defferent kinds of agricultural wastes as a substrate. The objective of this experiment was to optimize the concentration of corn cobs as a carbon source and liquid tofu waste as nitrogen source on xylanase production by Bacillus subtilis AQ-1. A 22 central composite experimental design was performed to optimize the corn cobs and liquid tofu waste concentration. A second order quadratic model and a response surface method showed that the optimum condition for xylanase production was 1.1 % (w/v) corn cobs and 0.00198 % (v/v) total N of liquid tofu waste with the highest xylanase production of 122.99 U/ml.Key words: bacillus subtilis AQ-1, xylanase, corn cob, liquid tofu waste

Learning models that develop students' argumentation and critical thinking skills are widely applied in senior high school. The purpose of this study was to verify the correlation between argumentation skills and scientific literacy skills of high school students on cell matter as the smallest structural and functional unit of life and cell bioprocesses. This research uses a correlational method. The sample of this research was the students of class XI MIPA SMAN 1 Batusangkar, numbering 34 people. Data on argumentation skill and scientific literacy skill were obtained from the test results in the form of an essay test using socio-scientific issues. Descriptive statistics, Pearson product moment correlation analysis techniques, and path analysis were used for data analysis. The results showed that there was a significant and positive relationship between argumentation skills and scientific literacy skills. In addition, argumentation skills have a statistically positive predictive effect on scientific literacy skills. It was revealed that argumentation skills acted as a partial mediating variable, so as stated in the theory, argumentation skills and scientific literacy skills were found to be very closely related. Thus, students' argumentation skills can be used to predict students' scientific literacy skills.

The study aims to produce feasible a contemplation-based learning model based on the aspect of validity and practicality for Biology prospective teachers. Research and development (RD) using ADDIE model was used where the participants in this study were three Biology Education lecturers, three experts, and 35 students who enroll at first semester at Biology Education department in Batusangkar State Islamic Institute (IAIN) as experimental subjects. The instruments used is observation, interview and questionnaire. Means and standard deviations were calculated for finding the level of validity and practicality of the prototype. The results showed that contemplation-based biology learning model meet the characteristics of the learning model and characteristic of contemplation. The contemplative approaches used through deep reading essays and paid attention to figures related to the subject matter of General Biology courses. The values cultivated are values contained in the subject matter. The values that contained in the material are islamic values, it is alasmaâ€™ ul husna. The contemplation-based learning model developed is feasible to be applied in the biology classroom with the most valid and very practical category. Thus, the contemplation-based learning model is a solution for overcoming the gap of serving science with self-knowledge and is an alternative learning model to integrate science and religion at Biology Education Department.

Learning media is one component of learning that is very important in achieving learningobjectives. Along with the development of the times, teachers must also be able to adjust theircompetence in creating technology-based media. One of the technology-based media is digital learningmedia. Through applications such as Canva, Flip Pdf Professional and Augmented Reality, teachers cancreate interesting learning media that can help achieve learning goals effectively. The method used inthe training in designing digital learning media for MGMP Biology teachers at SMA/MA Dharmasrayaconsists of the preliminary stage, namely analyzing problems and preparing training materials, theimplementation stage, by guiding teachers in designing digital media, and evaluation throughobservation and distributing questionnaires.

This research is motivated by the low ability of students to understand learning material even though at Raudatul Jannah Islamic Junior High School has used quite good technology which can be proven by the opening of digital classes, where students every day bring laptops and supporting facilities such as wifi, air conditioning, infocus, and comfortable classroom. With such facilities, the learning process should be more effective than other classes. However, what is found in the field is that students still do not understand learning. This can be seen from the learning outcomes of students who apply the digital learning process to the classification of living things in class VII.6 of Raudhatul Jannah Islamic Junior High School. Student learning outcomes show that cognitive abilities are still relatively low. Where the percentage of students' completeness is below 50%. The learning media used by the teacher are only in the form of power points, videos and textbooks without any new innovations so that students are less motivated to learn. Based on the above background, the author conducted a study to find a solution to this problem, namely by developing a Biology E-Module Based on Kvisoft Flipbook Maker on Classification of Living Creatures Class VII Islamic Junior High School Raudhatul Jannah Payakumbuh. This research is a development research using a 4-D development model. The development stage using the 4-D model has four stages, namely the definition stage, the design stage, the development stage, and the dissemination stage. However, in this study, the authors carried out to the development stage (develop). The instrument used in this study was a validation test sheet. Data analysis used descriptive analysis.Based on the research that has been done, a product is produced in the form of a Kvisoft FlipbookMaker-Based Learning E-Module. The E-Modul validation results obtained an average value of 85.69% which is categorized as very valid from the aspects of Guides and Information, Multimedia Content or Materials, Evaluation, Program Performance, Systematics and Aesthetics . And the Kvisoft FlipbookMaker Based Learning Module can already be used for learning

Farmers' knowledge about soil ecology, which is a key factor in increasing the productivity of agricultural products, needs to be evaluated considering that various counseling efforts to increase agricultural yields have not shown satisfactory results. Farmers still unequally manage farmland, providing excessive chemical fertilizers without regard to soil ecology. The purpose of this education is to evaluate the knowledge of the Women's Farmers Group (WFG) before and after conducting soil ecology education based on Islamic science. The subjects of this education were 15 members of WFG Bunga Padi, Jorong Kawai, Nagari Batu Bulek, Lintau Buo Utara, Tanah Datar, West Sumatra, Indonesia. The community-based research (CBR) approach is used in this educational activity. The stages of educational activities start from socialization, laying the basis of the research and the research design, providing pretests and materials, gathering information and analyzing data on biological factors, capillarity of groundwater, water holding capacity, soil aeration, soil fertility, and soil pH, and the evaluation (post-test). The results show an increase in knowledge and understanding among WFG Bunga Padi members after Islamic science-based soil ecology education. It is hoped that, over time, their mindset in managing farmland will be balanced, with less reliance on chemical fertilizers and more emphasis on soil ecology. As a result, Islamic science-based soil ecology education could have a role in improving farmland and laying the foundation for organic farming.
