Abstract

Insect-borne diseases remain a serious health problem in Indonesia, especially Dengue Hemorrhagic Fever (DHF), which can cause mass mortality in developing countries. Biological control, such as using chitinolytic bacteria, is needed to contain the spread of this disease. The methods used include sampling and preparation of shrimp waste, manufacture of chitin agar media, isolation of chitinolytic bacteria, macroscopic and biochemical characterization, maintenance of Aedes aegypti larvae, observation of effects on mosquito larvae, and data analysis. The results obtained there are six isolates that have different morphological characteristics: IS1 to IS6 isolates have a round shape and milky white color, with wavy edges on IS1, IS2, and IS4, and flattened on other isolates. At elevation, IS1 and IS5 are flat, while the other four isolates are convex. Microscopic tests found 2 isolates contained Gram-negative and 4 isolates Gram-positive. The biochemical test of all six isolates was positive. Effect of administration of the concentration that caused the highest time of death of larvae on the fourth day, with a concentration of 15% and an average number of deaths of 4.66. Based on the results of the study, it can be concluded that six isolates of chitinolytic bacteria were successfully isolated, with diverse morphological characteristics, including differences in shape and color. Microscopic tests identified two isolates as Gram-negative and four isolates as Gram-positive. The biochemical test results showed that the six isolates were positive in the catalase, Simmons Citrate Agar (SCA), and Triple Sugar Iron Agar (TSIA) tests. Concentration administration affected the time of larval death, with a concentration of 15% showing the highest mortality rate on the fourth day, with an average death toll of 4.66

Abstract

Jamblang fruit (Syzygium cumini) is used to treat diabetes mellitus, pain, inflammation, ulcers, and diarrhea, and in recent research, it has been proven to be used as a chemopreventive, radioprotective, and antineoplastic. Jamblang fruit contains several ingredients, namely: alkaloids, saponins, tannins, triterpenoids, flavonoids, polyphenols, and buchard. However, it is necessary to ensure whether jamun is safe for consumption by pregnant women, and a teratogenic test is needed. This research aims to determine the effect of jamblang fruit extract on maternal weight, number of fetuses, fetal length, fetal weight, hemorrhage, and morphological abnormalities in the fetus. This research is included in quantitative research using experimental methods with a Completely Randomized Design (CRD), which consists of 4 treatments and 5 replications. The experimental animals used were 20 female mice (Mus musculus) of the Balb/C strain, healthy mice aged 2 months, weighing 27-30 grams, and the mice were mature and ready to mate. Mice were divided into 4 treatment groups, namely the control group, the 100 mg/kgBB dose group, the 200 mg/kgBB dose group, and the 300 mg/kgBB dose group. Treatment doses of jamun fruit extract 70% ethanol are given on days 6 to 17 of pregnancy. Data analysis using SPSS showed that ethanol 70 % extract of jamblang fruit had no effect on maternal weight and fetal weight in mice (>0.05), but did affect fetal length, number of fetuses, hemorrhage, and morphological abnormalities in the form of open eyelids (p<0.05). Based on the research results, it can be concluded that administration of jamblang fruit ethanol extract can reduce fetal length and the number of fetuses. The 200 mg/kgBB and 300 mg/kgBB dose groups are doses that can cause teratogenic effects such as hemorrhage and open eyelids.

Abstract

Kuala Langsa is one of the coastal areas in Aceh known for its high biodiversity, including animals from the phylum Echinodermata. This study aims to identify Echinodermata species and analyze their populations about the physical and chemical environmental factors of the coastal waters. The research was conducted using a quantitative descriptive method in December 2024 along the coast of Kuala Langsa, Langsa City, with sampling carried out at three transects during low tide. The results showed that five species of Echinodermata from three classes were found. The diversity index was 2.190, indicating a moderate category; the evenness index was 0.830, classified as stable; and the dominance index was 0.358, indicating a low level of dominance. The highest abundance was recorded for Holothuria scabra, while Astropecten cingulatus had the lowest abundance and frequency of occurrence (66.7%). The other four species had a frequency of 100%. The highest similarity index (1) was found between Station II and Station III, while the lowest (0.88) was found between Station I and II and between Station I and Station III. Environmental parameters at the study site showed a temperature range of 29–33°C, pH ranging from 7.2 to 8.5, and salinity ranging from 20–27%. These findings provide important baseline data to support future biodiversity monitoring and highlight the ecological significance of the Kuala Langsa coastal ecosystem.

Abstract

The use of endophytic fungi as producers of bioactive compounds is popular among researchers today. One example of endophytic fungi that is currently widely studied regarding its role is DSE fungi. Determining the morphological structure and identification of DSE fungus as well as its function as a sustainable agricultural agent, are the goals of this study. Several scientific papers that are pertinent to the subject matter are gathered, chosen, and reviewed as part of the systematic literature review research methodology. Developing a research question, looking through pertinent literature, choosing studies with eligibility requirements and quality evaluation, and extracting data were the first stages of the study. Based on the data analysis, DSE fungi have the ability to increase plant productivity and resistance to biotic and abiotic stress, as well as their contribution to phytostabilization and nutrient accumulation. In addition, DSE fungi can produce beneficial secondary metabolites, such as growth hormones and bioactive compounds, which support plant health. The use of DSE fungi also has the potential to support plant growth in sustainable agriculture

Abstract

This study aims to determine the argumentation skills of grade 10th students towards socio-scientific issues at one of the senior high schools in Cileungsi, Bogor. This study was conducted using test and documentation techniques. The research method used is quantitative descriptive. Sampling was carried out using a purposive sampling technique; there are 128 students from 4 classes. The instruments used in this study were 5 standpoint questions related to the phenomenon of the spread of monkey pox and the test scores for virus material. The results of the study revealed that the quality of the written argumentation skills of class X students was mostly at levels 2 and 3, with an average percentage of 30.30% and 45.62% respectively. The findings imply that students are still in the process of developing higher-order thinking and scientific reasoning skills when engaging with socio-scientific issues. Therefore, science educators are encouraged to incorporate explicit argumentation-based learning strategies to promote deeper analysis, evidence-based reasoning, and the ability to construct coherent scientific arguments in response to real-world problems.

Abstract

Data literacy is an essential aspect in science and education, yet its integration in biology education remains underexplored. Competence in data literacy is essential for biology education students to conduct learning evaluation analyses that increase student learning performance. Grounded in Bandura’s social cognitive theory, this study investigates biology education undergraduates’ self-efficacy in data literacy during a statistics course. A convenience sample of 70 students completed a questionnaire assessing confidence (7 items), experience (4 items), and attitude (4 items) of data on a 5-point Likert scale. Additionally, students completed a data interpretation test (with biology-based data scenarios), rated their confidence on a 4-point Likert scale, and provided reasoning. Result revealed high levels of self-efficacy across all domains, consistent confidence during data interpretation tasks, and positive attitudes towards learning with data. The study contributes conceptually by linking perceived confidence and performance-based evidence of data literacy, highlighting implications for improving quantitative reasoning in biology education

Abstract

The global environmental crisis is not just a warning, but a call to action, and education is key. NSA Surabaya High School addresses this challenge through the unique learning innovation of kokedama, a Japanese art of farming that combines aesthetics and sustainability. More than just the practice of planting, kokedama is a powerful medium to instill ecological awareness in the younger generation. With a hands-on method combined with affective reflection, students not only learn farming skills, but also develop a deep empathy for nature and a real sense of ecological responsibility. This finding proves that contextual education can be a concrete solution to instill environmental awareness, solution to instill environmental awareness from an early age. We recommend this activity as a revolutionary strategy to create a generation of high school students who not only care but are also ready to lead the change for the sustainability of our planet.
