Bioscientist : Jurnal Ilmiah Biologi (BJIB), receiving and publishing article in the form of research (scientific article) in the field of biology education and utilization of biological research in learning. Moreover, this journal bridges the gap between research and practice, providing information, ideas and opinion, in addition to critical examinations of biology research and teaching. Through the coverage of policy and curriculum developments, the latest results of research into the teaching, learning and assessment of biology are brought to the fore. Special emphasize are as follow: 1. Research on Learning Biology (Biology Learning Materials at All Education Levels). 2. Pure Research of Biology Developed or Studied to the Sources, Materials, or Instructional Media Biology (Biology Learning Materials at All Education Levels and Application in Society). 3. Curriculum of Biology Education at all Education Levels. 4. Class Action Research (CAR) and Lesson Study in Biology. 5. Other Qualitative Research of Biology Education. 6. The School Management and Biology/Science Laboratory Management. 7. Biology Learning Evaluation. 8. Teacher Professional Issues/Trends in Biology Education. 9. Another Study for the Scope of Biology Education. 10. Research on Environmental Education.

Abstract

This study aims to examine the effectiveness of G. parviflora extract in reducing fasting blood glucose (FBS) levels and improving lipid profiles. The research design used was a laboratory experiment with a Completely Randomized Design (CRD). This study was conducted from June 2024 to January 2025 in the Laboratory of Biology Study Program and Integrated Mathematics and Natural Sciences Laboratory. Rats were divided into five groups, namely negative control, positive control (glibenclamide 5 mg/kgBB), and three treatment groups of bribil extract with doses of 400 mg/kgBB, 600 mg/kgBB, and 800 mg/kgBB. Parameters measured included GDP levels and lipid profiles (total cholesterol, triglyceride, HDL, and LDL levels). Data analysis was performed using one-way ANOVA test and Tukey's Post Hoc further test. The results showed that the ethanol extract of bribil (Galinsoga parviflora) doses of 600 and 800 mg/kgBB effectively reduced GDP levels, total cholesterol levels, triglyceride levels, LDL levels, and HDL levels of rats (Rattus norvegicus) T2DM model. These results indicate that bribil extract has potential as a therapeutic agent for T2DM. These findings suggested the possibility of Galinsoga parviflora extract as a DMT2 therapeutic agent.

Abstract

This study aims to determine the effect of rosella flower extract on reducing blood glucose levels in alloxan-induced white rats. The research method used is an experiment conducted in the laboratory with a complete randomized design (RAL) pattern. The number of samples used was 24 white rats consisting of 6 treatment groups and 4 replicates. Normal control group (Kn) is a group that is only given food and drink, negative control group      (K-) is a group given alloxan induction, positive control group (K+) is a group given alloxan induction and metformin synthesized drug, treatment groups I, II, and III are groups given alloxan induction and rosella flower extract at a dose of 50 mg/kg BB, 100 mg/kg BB and 150 mg/kg BB. The data obtained were analyzed by ANOVA statistical test. The results showed that rosella flower extract had an effect on reducing blood glucose levels in white rats induced by alloxan. The most effective dose in reducing blood glucose levels in white rats is a dose of 150 mg/kg.

Abstract

This study aims to analyze the relationship between diet and physical activity with the nutritional status of students of SMP Negeri 19 Palu. This study used a cross sectional design with a quantitative approach and analytic observational type. The subjects were 77 students of class VIII (aged 13-15 years) who were selected using simple random sampling technique. Data were collected using FFQ (Food frequency Questionnaire) to assess diet and APARQ (Adolescent physical Activity Recall Questionnaire) for physical activity, both validated instruments from previous studies. As well as anthropometric measurements (height and weight) using the Body Mass Index (BMI) to determine nutritional status. The results of the analysis using the chi-square test showed that there was a significant relationship between diet and nutritional status (χ²(3) = 8.772; p = 0.032), and between physical activity and nutritional status (χ²(4) = 9.919; p = 0.042) Respondents with a good diet and moderate to vigorous physical activity tended to have normal nutritional status, while poor diet and light physical activity were more common among students with abnormal nutritional status. These findings suggest that diet and physical activity play an important role in determining the nutritional status of adolescents. The implications of this study emphasize the importance of educational intervention programs in the school environment to support healthy lifestyles and prevent nutritional problems among students.

Abstract

This research aims to describe the level of diversity of insect species in various agricultural lands in Basidondo District, Tolitoli Regency, Central Sulawesi. The research was conducted in January-March 2025 using descriptive methods and quantitative approaches that aim to make a description or descriptive of a situation objectively using numbers. Insect sampling techniques were carried out with four types, namely pitfall trap, light trap, sweeping net, and hand collection. The insects obtained were then identified according to the taxonomic order with the help of insect determination key book, and analyzed using Shannon-Wiener diversity index (H'). The results showed that there were 24 types of insect families that were successfully identified. The value of the diversity index (H') was 3.13, which was classified as high diversity. These results indicate that agricultural land in Basidondo District has environmental conditions that support the diversity of insect communities, which can contribute to the stability of agricultural ecosystems. High diversity indicates a balance between insect pests and natural enemies, as well as the role of insects as pollinators and decomposers.
