Orthosiphon aristatus is a medicinal plant that has the potential as a natural antibacterial agent. This study aims to evaluate the effect of cat's whiskers leaf extract on microbial growth using Nutrient Agar (NA) media with variations in extract concentrations of 100 gr, 50 gr, and 25 gr. Antibacterial activity tests were carried out using the well diffusion paper disk method, and observations of microbial growth inhibition zones were carried out after incubation for 24 hours at 37°C. The test results showed that there was inhibition of microbial growth that varied according to the concentration of the extract used; a concentration of 100 gr gave the largest inhibition zone compared to 50 gr and 25 gr. Data analysis showed that increasing extract concentration was directly proportional to increasing antibacterial effectiveness. These findings indicate that Orthosiphon aristatus leaf extract has the potential as a natural antibacterial that is effective in inhibiting microbial growth in NA media, so it has the potential to be developed as an active ingredient in pharmaceutical formulations.

This study uses a qualitative method with a literature review approach to examine the effectiveness of the two-phase method in solving linear programming problems. The two-phase method is one of the techniques in linear programming used when the objective function does not have a feasible initial solution directly. Through the exploration and analysis of various scientific literature sources from 2019 onwards, this study finds that the two-phase method can systematically provide optimal solutions, especially in complex problems with multiple constraints. Previous research has shown that this method is effective in accelerating the identification of basic feasible solutions and minimizing unnecessary iterations compared to the standard simplex method. Additionally, the two-phase method offers better numerical stability and high reliability in both industrial and educational applications. However, its effectiveness largely depends on the understanding of the algorithm and the ability to design an appropriate mathematical model. The results of this study are expected to contribute theoretically to the development of efficient solution techniques for linear optimization problems.

These results can also be seen from the pretest with an average value of 34 and posttest with an average value of 92, so the average N-Gain Score was 88.52%. So, it can be concluded that the development of animated video learning media can improve the Mathematical problem solving abilities of 6th Grade of Elementary School students.

Energy is the ability to do or change something. It can be found in various forms in everyday life, such as electrical energy flowing through cables, thermal energy produced by stoves, or kinetic energy generated by vehicles. Energy can also come from natural sources, such as the sun, wind, and water. This research aims to enhance students' ability to think critically in understanding the material on energy and its changes. This research uses a quantitative method; data were collected from 27 students through 10 questions discussing the concept of energy. Effective education not only helps students better understand what they are doing, but also prepares them to face environmental issues in the future. In addition, innovative learning methods such as project-based learning should be incorporated into the curriculum to build critical thinking skills. Therefore, it is expected that this research will help improve the energy education curriculum in elementary schools and encourage students to participate more actively in sustainability issues.

This article explores the nature of the philosophy of Islamic education and its integration with the philosophy of mathematics in the learning process. The philosophy of Islamic education is rooted in the Qur’an and As-Sunnah and is further reinforced by the thoughts of Muslim philosophers. It encompasses three main aspects: ontology (the nature of existence), epistemology (the sources and methods of acquiring knowledge), and axiology (values and purposes). Islamic education aims not only to shape individual character but also to build a holistic educational system based on Islamic values. In this context, education is not merely a process of knowledge transfer but a means of fostering moral and spiritual development in learners. On the other hand, the philosophy of mathematics from the perspective of Islamic education emphasizes that mathematics is not solely an exact science of arithmetic, but also a discipline closely related to ethical and moral values in Islam. Mathematics is viewed as part of the divine order of Allah’s creation, reflecting His greatness. Therefore, the integration of Islamic educational philosophy and mathematical philosophy in learning offers a deeper approach to mathematical concepts. This approach not only enhances students’ cognitive understanding of the material but also instills spiritual awareness and values of faith and piety. By combining scientific and religious aspects, the learning process becomes more systematic, meaningful, and aligned with the comprehensive goals of Islamic education.

Indonesia, a leading palm oil producer, generates 1,250 tons of Oil Palm Empty Fruit Bunches (OPEFB) waste daily, typically disposed of through polluting combustion. This study explores repurposing OPEFB as a substrate for erythritol production, a popular sweetener with minimal impact on blood sugar. The research utilized Moniliella pollinis mutant SP5, a yeast capable of producing erythritol from various substrates. The process involved acid hydrolysis of OPEFB followed by fermentation. When fortified with 15% v/v molasses, OPEFB successfully served as an optimal carbon source for erythritol production, achieving a mass yield of 0.2878 g/g. Further improvement came through the use of ethyl methane sulfonate (EMS) mutagenesis, with the best mutant (mutant 7) reaching a yield mass of 0.3298 g/g and volumetric productivity of 0.0534 g/L/h. This research aims to advance Indonesia's self-sufficiency in erythritol production while providing a sustainable solution for OPEFB waste reduction, simultaneously addressing economic and environmental concerns.

The study was conducted to evaluate the effects of microbial inoculants and nutrient levels on the agronomic performance of dry direct-seeded NSIC Rc192 rice under aerobic conditions. Six biofertilizer treatments (control, Bio-N, BioGroe, Mykovam, MykoPlus, and Avatar) were combined with four nutrient levels (0 %, 25 %, 50 %, and 75 % NP + full K). The study aimed to assess the impact of these treatments on root colonization, tiller production, and overall plant growth. Root and soil colonization at 60 days after sowing (DAS) revealed that MykoPlus facilitated more effective root colonization than other inoculants. However, unfavorable environmental conditions, including high temperatures and moisture deficits, negatively impacted tiller production and grain yield. Despite these challenges, BioGroe showed the most promise, significantly enhancing root development and tiller count, particularly when combined with 50 % NP + full K. The study concluded that microbial inoculants, especially BioGroe, can improve rice growth under aerobic conditions, but environmental factors are crucial in determining their effectiveness. Further research is needed to optimize these inoculants for varying environmental conditions to maximize their benefits in rice cultivation.
