ABSTRAK Daun tapak liman (Elephantopus scaber L) dapat menghambat pertumbuhan bakteri karena mengandung senyawa metabolit sekunder seperti flavonoid, fenol, tannin, saponin, dan alkaloid, sehingga dapat mengobati penyakit diantaranya demam, malaria, batuk, disentri, dan diare. Pemberian antibakteri ekstrak methanol daun tapak liman merupakan salah satu cara untuk menghambat pertumbuhan bakteri Escherichia coli. Penelitian bertujuan untuk mengetahui diameter zona hambat (sekeliling daerah tersebut tidak ditumbuhi bakteri) dari ekstrak methanol antibakteri daun tapak liman (Elephantopus scaber L) terhadap pertumbuhan bakteri Escherichia coli dengan konsentrasi 25%, 50%, 75%, dan 100%. Metode yang digunakan yaitu eksperimental secara Difusi disk. Hasil penelitian menunjukkan bahwa diameter zona hambat ekstrak methanol daun tapak liman (Elephantopus scaber L) terhadap pertumbuhan bakteri Escherichia coli pada konsentrasi 25% dengan rata-rata zona hambat yaitu 10,6 mm, 50% (15,6mm), 75% (20,3 mm), dan 100% (22,6 mm). Berdasarkan hasil, maka dapat disimpulkan bahwa ekstrak methanol daun tapak liman dapat menghambat pertumbuhan bakteri Escheria coli yang ditandai dengan adanya zona bening disekitar paper disk. Kata Kunci: difusi disk, daun tapak liman, antibakteri,Escherichia coli ABSTRACT (Elephantopus scaber L) leaves can inhibit the growth of bacteria because they contain secondary metabolite compounds such as flavonoids, phenols, tannins, saponins and alkaloids, so they can treat diseases including fever, malaria, cough, dysentery and diarrhea. Providing antibacterial methanol extract from Tapak Liman leaves is one way to inhibit the growth of Escherichia coli bacteria. The research aims to determine the diameter of the inhibition zone (the area around which bacteria do not grow) of the antibacterial methanol extract of tapak Liman (Elephantopus scaber L) leaves on the growth of Escherichia coli bacteria with concentrations of 25%, 50%, 75% and 100%. The method used is experimental disk diffusion. The results showed that the diameter of the inhibitory zone of the methanol extract of tapak Liman (Elephantopus scaber L) leaves on the growth of Escherichia coli bacteria at a concentration of 25% with an average inhibitory zone of 10.6 mm, 50% (15.6 mm), 75% (20 .3 mm), and 100% (22.6 mm). Based on the results, it can be concluded that the methanol extract of tapak Liman leaves can inhibit the growth of Escherichia coli bacteria which is indicated by the presence of a clear zone around the paper disk.

The utilization of plants as traditional cosmetics has been used by Gayo women in Bener Meriah Regency for generations. The use aims to maintain natural beauty to minimize the use of chemicals that often cause many side effects. Information related to the species of plants used has not been recorded properly, so it is feared that the information will be degraded over time. This study aims to find out about the species of plants used as natural beauty care ingredients by Gayo women in Bener Meriah. This research used an exploratory survey method. Sampling was conducted by snaw ball sampling. Samples included housewives from the Gayo tribe, teenagers, and people who use plants as hair care. Data were analyzed descriptively qualitatively and data were displayed in the form of tables and figures. The results showed that there are 45 species of plants used in the beauty care of Gayo women spread in diverse families. Rutaceae and Poaceae are the families with the most species, totaling 6 species.

This study aims to describe the role of accompanying teachers in improving students’ learning achievement on the topic of Growth and Development at SMP Negeri 6 Banda Aceh. The research employed a quantitative approach using a quasi-experimental method. The subjects consisted of 32 students of Grade VII-8 in the 2025/2026 academic year. Data were collected through learning achievement tests (pre-test and post-test), observation of learning activities, and interviews with the accompanying and biology teachers. Data analysis was conducted descriptively and inferentially using the Normalized Gain (N-Gain) formula to determine the improvement in students’ learning outcomes. The results showed a significant improvement in student achievement, with the average pre-test score of 60 increasing to 88–90 on the post-test. The presence of an accompanying teacher played an important role in creating an active and structured learning atmosphere, supporting students who experienced learning difficulties. Collaboration between the accompanying teacher and the biology teacher in planning, implementing, and evaluating the learning process proved effective in enhancing students’ conceptual understanding, motivation, and learning outcomes on the topic of growth and development. Therefore, it can be concluded that accompanying teachers play a strategic role in improving students’ learning achievement through academic, motivational, and collaborative assistance in the classroom. The application of this mentoring model can serve as an effective alternative to enhance the quality of science learning at the junior high school level.

Mathematics is the main subject. Mathematics solves many problems in many fields, namely biology, physics, chemistry, astronomy, calculus, statistics, computer programming, and others. However, many students often consider mathematics as a complex subject. One of the reasons is that students are not trained to include mathematics the problem-solving process. Mathematical, logical intelligence is the ability to solve aproblem by mathematics. Living in the 21st century demands the use of technology in almost all aspects of life. This study aims to determine the effectiveness of animation media in improving the mathematical logic intelligence of fifth-grade students at an elementary school with 37 students. The research method is a quasi-experiment with a control-group pretest-posttest design. Research instruments in the form of tests and documents. Data analysis techniques using t-test and N-Gain calculation. The results showed that using animation media to learn mathematics effectively improves mathematical logic intelligence. It is evidenced by the experimental class N-Gain score of 69% with a reasonably practical category, which is higher than the control class N-Gain score of 52% with a less effective category. The t-test results show a difference in mathematical logic intelligence between students who learn using animation media and those who do not, with a significance value smaller than 0.050, namely 0.036. This research will inform that mathematical logic intelligence can be carried out using animation media. The other researcher can continue the research by finding the mathematical logic intelligence indicator that contributed the most to mathematics learning activity.
