The goal of this study was to genetically link natural materials derived from Tinospora crispa L with Berberine to dihydrofolate reductase-thymidylate synthase (DHFR-TS). Method: The ligand berberine (CID: 2353) was obtained from Pubchem, while the protein DHFR-TS (PDB ID 2bl9) was obtained from Protein Data Bank. The ligands and proteins interacted with HEX 8.0.0.0 and were visualized with Discovery Studio. The researchers discovered a positive interaction between berberine and DHFR-TS, observed at four amino acid residues that bind to the protein TYR125, ILE121, LEU45, and MET54. Van der Waals interactions, hydrogen bonds, Pi-Sulfur, Pi-Alkyl, and Pi-Stalked interactions all contribute to strength and stability. In conclusion, berberine has the potential to act as a DHFR-TS inhibitor and thus prevent malaria.ABSTRAK: Tujuan penelitian ini adalah memanfaatkan bahan alam yang berasal dari Tinospora crispa L dengan kandungan utama Berberin dengan dihydrofolate reductase-thymidylate synthase (DHFR-TS) secara genetik.

This study aims to analyze the suitability of HOTS (Higher-order Thinking Skills) based on critical thinking on the Odd Semester Final Examination questions for high school biology lessons in the East Cirebon Region. The research subjects were schools in the Cirebon area, namely SMAN 1 Lemahabang, MAN 3 Buntet Pesantren Cirebon and MA NU Putri Buntet Pesantren Cirebon. Data analysis is presented in the form of percentages and then described based on critical thinking indicators (characteristic thinking) based on Facione, (2011) on the Biology Final Semester Exam (UAS). The odd semester final exam (UAS) for biology subjects already contains critical thinking skills, but the percentage is still low. The most dominating indicator is interpretation. Based on this research, it shows that the questions made by the teacher are not sufficient to cultivate students' critical thinking skillsABSTRAK: Penelitian ini bertujuan untuk menganalisis kesesuaian HOTS (Higher-order Thinking Skills) berdasarkan critical thinking pada soal Ujian Akhir Semester ganjil pelajaran biologi SMA se-Wilayah Cirebon Timur.

This research aimed to determine the effectiveness of Google Classroom learning on the learning outcomes of students of STKIP Pembangunan Indonesia at the Biology Study Program. The benefit of this research is that the results are expected to contribute to the teaching and learning process that lecturers will carry out, especially the application of the Google Classroom in improving students’ learning outcomes. The researchers employed the quantitative approach with a pre-experimental design of one group pretest-posttest, which provided a pretest before the treatment. After the treatment, the researchers administered a posttest on the Vertebrate Zoology course. The data collection technique applied in this research was a description test administered during the pretest and posttest. This research found that the students’ learning outcomes in the pretest were 36% in the completeness level. There was an increase in the posttest with a 72% completeness level. The results of hypothesis testing using an independent sample t-test obtained value of 3,149, which was higher than tobserved of 1.67. The results showed that students’ learning outcomes after using Google Classroom were significantly better than before the application of Google Classroom. This research proved that Google Classroom was an online learning method that can improve the quality of education, especially students’ learning outcomes, and could overcome the constricted learning process with the availability of actual classrooms.

This research aimed to determine the mitotic abnormalities, changes in the number of chromosomes, mitotic index, and the number and length of kepok abu banana plantlet roots due to administration of 0.1% colchicine in tissue culture media. This research was performed at the Botanical Laboratory of the Biology Department, Faculty of Mathematics and Natural Sciences, UNILA. This research compared the cytology by employing the Squash method between root tip cells of kepok abu banana plantlets after administering 0.1% colchicine and the control group. The researchers analyzed the data descriptively and presented them in tables and bar charts. The results showed that the administration of 0.1% colchicine resulted in mitotic abnormalities. It also increased the number of chromosomes in the controls 2n=3x and 2n=3x+4. The mitotic index decreased, and the average number of roots was lower. However, the size was longer compared to the control group.

This study aimed to determine the effect of Catharanthus roseus leaves extract on kidney histology of mice aspartame-induced. Mice were divided into 4 groups, namely the negative control group (K-) without treatment, the positive control (K+) given aspartame 0.02 mg/day, the dose group 1 (D1) was given aspartame 0.02 mg/day and continued with the C. roseus leaves extract at a dose of 0.42 mg/kg. Group 2 (D2) was given aspartame 0.02 mg/day followed by C. roseus leaf extract at a dose of 0.84 mg/kg BW. IP administered aspartame for 14 days, and C. roseus leaves extract was administered by gavage for 12 days. The data obtained were analyzed by One Way ANOVA and DMRT test with a significance level of 0.05. The results showed that the induction of aspartame at a dose of 0.02 mg/day in mice increased the average number of proximal tubular necrosis cells. Catharanthus roseus leaves extract administration at 0.42 mg/kg BW and 0.84 mg/kg BW for 12 days can reduce the number of proximal tubular necrosis cells in aspartame-induced mice. Thus it can be concluded that the administration of C. roseus leaves extract can reduce the proximal kidney tubules necrosis but has not been able to reach normal conditions yet.
