Authors:Farihatun Nafi'ah, Muhammad Iqbal Filayani Pages: 1 - 14 Abstract: Creating students who are superior in spiritual and scientific terms can be done through learning activities that integrate Islamic science. The integration of Islamic science in science-biology learning can be done using the Al-Qur'an integration model as a source of inspiration and confirmation. The aim of this research is to describe the planning, implementation and evaluation of the implementation of the integration of science and the Koran in science-biology learning on respiratory system material for class VIII students at MTs Negeri 3 Blitar. The type of research used is descriptive qualitative research with data collection techniques using interview, observation and documentation methods. The results of the research show that of the two class VIII teachers, namely SA1 and SA2, one of them (SA2) implemented the integration of Al-Qur'an science into the respiratory system material which can be seen from the planning, implementation and evaluation stages of the learning carried out. SA1 has not implemented the integration of Al-Qur'an science at the planning and evaluation stages. SA1 has implemented Al-Qur'an science at the implementation stage, but not in the respiratory system material. Therefore, this integration is a form of development carried out by teachers personally so that not all teachers have the ability to implement it.

Recently, it is getting wide attention due to its important use as biofuel in industrial scale. The massive propagation is needed to meet industrial needs. Beside the use of conventional seedling production technique, the use of tissue culture for mass propagation is one of the alternatives to address this problem. This research was conducted to develop standard protocol for micropropagation of red calliandra through tissue culture. Here, the first step for that purpose was reported. The MS medium was used for basal media treatment. The seed source was stored for eight months under 5oC. This research was carried out in two stages i.e. 1) seed germination test and 2) shoot initiation and multiplication treatment. Each stage was arranged in experimental method. The result showed that seed were pre-treated with warm water (40oC) gave 62.5% germination under red light when compared to control (37.5%, pre-treated with water at 25oC under white light) three days after planting. Conversely, there is no striking differences of germinated seed percentages between light treatment at 25oC. Furthermore, it was found that addition of 2 mg/L BAP gave better result in shoot initiation and number of shoots formed from nodal explants after four weeks in treatment media. These results indicated that mass propagation of red calliandra can be done through tissue culture where multiplication stage is one of the important steps to produce multiple shoots only from single nodal explant.

Authors:Hartati Wulandari, Zulfarina Zulfarina, Evi Suryawati Pages: 65 - 76 Abstract: Based on the results of observations that have been carried out in several high schools in Pekanbaru, it can be concluded that it is very necessary to develop teaching materials in the form of E-modules because teachers only use textbooks and LKPD during the teaching and learning process, teachers have never used E-modules during learning. And teachers do not use learning resources that can support students' critical thinking skills. Students experience difficulty in providing arguments when asked for written explanations to solve problems, and students are unable to analyze and synthesize problems. The aim of this study was to determine the effectiveness and efficiency of the electronic components of the immune system of PBMP. It is hoped that this study can help teachers to choose new learning materials as an alternative to support learning during the 4.0 revolution, and to provide learning experiences using electronic components. PBMP (problem-based empowerment) and encourage learning. Students will study the resources of the immune system so that students can think critically to develop. The efficiency test results are classified as very efficient which can be seen in the average relevance of 96.08% in the most effective category.

Authors:Cornelia Dolfina Maatoke, Zahriska Dewani, Fuzi Suciati Pages: 113 - 121 Abstract: This study aims to determine the morphological and physiological properties of Phosphate Solubilizing Microbes (MPF) and Azotobacter. The method used was to test morphological properties using gram staining and physiological properties tests using biochemical tests based on cell activity by looking at the interaction of bacterial metabolism with the test reagent media. Data analysis examined the reaction to the isolated morphological and physiological test media. The results showed that based on the morphological observations of the MPF, the colonies showed a slightly milky white color, round, convex, slimy shape, 1-2 mm in diameter and flattened, and Gram-positive. Azotobacter shows the characteristics of transparent color, convex, flat edges, slightly slimy, an average diameter of 1 mm, and is Gram-negative; whereas based on the results of physiological test observations for catalase and oxidation tests, the characteristic of MPF and Azotobacter, each showed a positive (+) effect, as seen from the formation of bubbles in the test results. Tests for motility and O2 requirements show that both bacteria are motile, mobile and aerobic or require oxygen for growth. The observations of resistance in the pH range showed that Azotobacter was more resistant to extreme acid-base pH with a pH range of 3-9, while MPF could only survive in a pH range of 5-9. Tests of glucose and sucrose fermentation showed that MPF did not form gas bubbles (-) and no color change(-). At the same time, Azotobacter showed the formation of gas bubbles (+) but no color change (-). PubDate: 2024-04-18 DOI: 10.31849/bl.v11i1.19518 Issue No:Vol. 11, No. 1 (2024)
