Abstract

Background: Rousettus amplexicaudatus is widely distributed across Indonesia, including the Suruman Cave in South Bengkulu. Due to similarities in morphology within the Rousettus group, identification can be challenging. We conducted a molecular analysis using COI and Cytochrome b genes from mitochondrial DNA to explore its genetic traits. DNA was extracted from the blood tissue of seven individuals from the Suruman Cave population, and gene amplification was performed with 20 bp primers. Sequence data were analyzed using MEGA XI software. Results: As a result, characteristics of the COI gene, which is 897 bp in length, were characterized by a high frequency of base pairs Adenine-Thymine (55.5%) and Guanine-Cytosine (44.5%), with the majority of the DNA sequence exhibiting a high degree of conservation sites (97.8%). The average intrapopulation genetic distance based on the COI gene was 0.77%, with four specific sites for R. amplexicaudatus Suruman Cave. The Cytochrome b gene, which is 635 bp long, is characterized by Adenine-Thymine base pairs of 53.7% and Guanine-Cytosine of 46.3%. Cytochrome b is more conserved than the COI (99.1%). The average intrapopulation genetic distance based on the Cytochrome b gene is 0.3% and has no population-specific sites. Conclusions: Both sequences showed a consistent pattern in phylogenetic tree analysis, which suggests the Suruman population is the group of R. amplexicaudatus. Therefore, these sequences can be proposed as molecular markers for R. amplexicaudatus, particularly when compared to the whole sequences of the COI and cytochrome b.

Abstract

Test the effectiveness of electronic modules (e-Modules). The hope of this research is to test the effectiveness of Self Organized Learning Environment (SOLE) based e-Modules. This type of research is research and development which refers to the ADDIE type of development (Analysis, Design, Development, Implementation and Evaluation). The resulting product is an e-Module based on Self Organized Learning Environment (SOLE), which was carried out effectively by 34 students. The instrument used is an essay test. The instruments that have been developed are used for data collection. The resulting data was then analyzed quantitatively. Based on the research results, it shows that the level of effectiveness of SOLE-based e-Modules in terms of student learning outcomes is 0.7, which is in the effective category with a medium level. So the SOLE-based e-Module is effective at a moderate level. The suggestion in this research is that it is recommended for researchers who want to continue this research to conduct influence-based experimental research to find out more about how this e-Module will work if it is tested in several schools.

Abstract

Background: Background: Shallots are a horticultural product widely consumed in Indonesia. In 2021, shallot production will decline. This is due to pest and disease attacks on plants. Fusarium sp. is a pathogen that causes the primary disease in shallots, namely moler disease, which can cause losses of up to 50%, so control activities must be carried out. This research aims to determine the potential of Streptomyces sp. bacteria from exploring shallot planting areas in Bojonegoro against Fusarium sp. fungi in vitro. Methods: This study used 15 isolates of Streptomyces sp. from exploration results tested with Fusarium sp. using the dual culture method, and negative control (only Fusarium sp.) repeated 3 times for each treatment. Observations were carried out every day for 7 days by observing the growth of Fusarium sp. hyphae and their inhibitory power. Result: The research showed that isolate S8 had the highest inhibitory power, 49.5%. Meanwhile, the one with the lowest results was isolated S1, 34.5%. From the chitinase test results, the chitinocytic index of isolate S8 was 5.2, which is in the high category. Meanwhile, the isolate S8 cellulolytic index was 4.8 and was classified as high. Conclusions: All Streptomyces sp.p isolates inhibited the growth of Fusarium sp., which was characterized by an inhibition zone compared to the control treatment.

Abstract

Background: S. litura has a wide host range, so it has the potential to become a pest on various types of plants, including food crops, horticulture, and plantations. The quality and quantity of food determine the nutritional needs of insects, so they greatly influence their growth and length of development. This research aimed to determine the life cycle length, body length, pupa weight, fecundity, and prevalence of S. litura in several natural foods from the same plant family. Method: This study used non-factorial RAL with five treatment levels and was repeated 7 times. Results: The feed that survived to the imago stage was cauliflower, green and white mustard greens, and produced eggs. The fastest life cycle for cauliflower feed is 24 days, green mustard greens are 30 days, and white mustard greens are 25 days. The eggs that successfully hatched were in the Sh and Sp treatments, with Sh with 12% egg fertility and Sp 74%. Conclusion: The different types of 5 different feeds show different growth and development results for S. litura depending on the amount and content of the feed itself.

Abstract

Background: This research is motivated by students' systems thinking competence and digital literacy, which are still very low. This is due to the delivery of biodiversity material, which is still very conventional, and learning that is still teacher-centred. Therefore, this research will use the application of Lumi-based ESD learning. This research aims to determine the effect of implementing Lumi-based ESD learning to train systems thinking and digital literacy in the context of SDGs 15. Method: The type of research used in this research is Quasi Experiment with a Non-Equivalent Control Group Design research design. The sampling technique uses purposive sampling, namely class X1 as the experimental class and X5 as the control class. The instruments used were systems thinking competency tests, digital literacy questionnaires, attitude scale sheets, and student response questionnaires. Results: The research results stated that the N-Gain Value of systems thinking competency in the experimental class was outstanding, with a value of 0.65 in the medium category compared to the control class, with a value of 0.29 in the low category. Meanwhile, the N-Gain digital literacy value of students in the experimental class, with a value of 0.45 in the medium category, was compared with the control class, with a value of 0.18 in the low category. Judging from the hypothesis test, systems thinking, and digital literacy show significant differences with both values at sig (2-tailed) 0.00. Conclusion: From this research, it can be concluded that applying Lumibased ESD learning affects practicing systems thinking and digital literacy in SDGs 15. The findings in this research are that applying Lumi-based ESD learning is much better for practicing systems thinking competencies than digital literacy.

Abstract

Background: The decrease in the output and quality of pomelo oranges due to improper growing methods and fruit fly pests poses a challenging control problem. The objective of this study is to ascertain the impact of abiotic influences on the variations in the population of fruit flies. Method: Observations were conducted to determine the correlation between the emergence of adult fruit flies from contaminated fruit and the population of fruit flies in the field. The study was conducted in Sukomoro District, Magetan Regency, from January - May 2024. This study integrates two techniques, explicitly using traps (Steiner traps) and host rearing. Secondary data collection encompasses gathering information on rainfall, temperature, humidity, and agriculture patterns. Results: The research findings identified two species of fruit flies in pomelo orange plantations, specifically Bactrocera carambolae and B. dorsalis. The rate of imago emergence ranges from 86% - 92%. Conclusion: each emergence is accompanied by a substantial rise in the fly population. There is no association between abiotic elements like rainfall and humidity and the changes in the fruit fly population. A statistically significant moderate correlation exists between the emergence of imago and trapped fruit flies, namely (r) of 0.616 (p) of 0.001.

Abstract

Background: Pekasam, or Bekasam, is a fermented fish product that can potentially produce lactic acid bacteria (LAB). This study aims to isolate and characterize LAB from Pekasam from Sambas Regency. TPC results on MRS media showed that Pekasam from Sambas Regency can potentially contain LAB with a total colony of 107 CFU/g. The isolates were identified for their colony and cell shape so that three selected isolates were obtained, namely SB1(1), SB3(1), and SB3. Methods: Isolates were characterized for proteolytic activity, hemolytic activity, low pH tolerance, tolerance to the presence of bile salts, carbohydrate metabolism, and potential antimicrobial activity. All isolates had round colonies, convex or raised surfaces, flat edges, milky white, rod-shaped cells, and were classified as gram-positive bacteria. Results: All isolates showed proteolytic activity, ɤ-hemolysis, had low pH tolerance with viability <60% at pH 2 and 3, were resistant to bile salts with viability <73% at NaDC concentrations of 0.2 and 0.4 mmol, were able to metabolize carbohydrates and had antimicrobial activity. The selected isolates were identified as Lactobacillus species and were homofermentative. Conclusion: The three selected isolates can potentially be homofermentative LAB of Lactobacillus species.

Abstract

Background: Innovation in learning methods is essential to improve students' creativity and entrepreneurial competence. The STEAM learning model with ecoprint-based Student Worksheets (LKPD) is one method that can be used. This study aims to determine the effect of the STEAM learning model through eco print-based Student Worksheets (LKPD) on students' creativity and entrepreneurial competence with students whose learning uses conventional learning models (discovery learning). Method: This study used a quasi-experimental method with a Non-equivalent control group design. The research sample selection technique used purposive sampling of class X students at a high school in Sukabumi City for the 2023/2024 academic year. Results: The study showed that students' creativity in the experimental class obtained an average value of 82±0.24 percent and entrepreneurial competence of 86±0.38 percent, both in the outstanding category. The hypothesis test results obtained a significance value of Sig (2-tailed) 0.000 for both variables, so H0 was rejected and H1 was accepted. Conclusion: This study implies that using the STEAM model through Ecoprint-based LKPD can be an alternative effective learning model in improving students' creativity and entrepreneurial competence. The implications of this study indicate the need for broader development of the Ecoprint project-based STEAM model to support practical and innovative learning.

Abstract

Background: Seaweed cultivation in marine environments offers ecological and economic benefits, but the increasing presence of microplastics poses risks. This review explores cultivation techniques and the impact of microplastic pollution on seaweed growth, nutrient absorption, and health. Methods: Literature was sourced from Google Scholar and academic databases using keywords related to seaweed cultivation and microplastic pollution, focusing on peer-reviewed articles, books, and credible reports from the past decade. Studies were selected based on methodological rigor, relevance, and source credibility. The literature was synthesized to highlight key patterns, trends, and knowledge gaps on the impact of microplastic pollution on seaweed farming. Results:  Seaweed aquaculture provides food, biofuel, pharmaceuticals, and environmental benefits, varying cultivation methods by species, environment, and product. Despite growing demand, microplastic pollution threatens seaweed farming and marine ecosystems. This study explores seaweed’s role in microplastic retention, its potential as a bioindicator, and its broader impact on marine health. Urgent action is needed to address plastic and microplastic emissions and mitigate long-term environmental and health risks. Conclusions: Seaweed aquaculture provides food, biofuel, and ecological benefits. However, microplastic pollution threatens its sustainability. Immediate action is required to address plastic pollution, as it poses long-term risks to marine ecosystems and human health. Governments are increasingly focusing on mitigation measures to address these pressing issues.

Abstract

Background: Science Process Skills (SPS) are vital in science learning but often underdeveloped. This study examines how the Discovery Learning (DL) model improves SPS and identifies which SPS aspects are developed in class VIII of SMP Islam Sudirman Suruh during 2023/2024. Methods: This study uses a qualitative descriptive method with triangulation (observation, interviews, documentation), involving one class of 13 grade VIII students at SMP Islam Sudirman Suruh (2023/2024) selected purposively based on teacher recommendations. The researcher serves as the primary instrument, supported by observation sheets and interview guidelines, with data analyzed through reduction, presentation, and verification. Results: The average percentage of total KPS in the Work and Energy material reached 83.2% (Good category), and increased in the Simple Machine material to 87.4% (excellent category). KPS aspects, including the use of instruments/materials and conducting experiments, demonstrated high achievement (excellent category). In contrast, the aspect of implementing concepts showed the lowest achievement, despite an increase (from Fair to Good). Interview data confirmed the positive role of DL in stimulating students' activeness and KPS. Conclusions: The implementation of the Discovery Learning model has a positive and significant impact on improving the Science Process Skills of eighth-grade students at SMP Islam Sudirman Suruh in science classes, with an overall average reaching the "Good" category. This model is effective in training various aspects of KPS, although the implementation of the concept requires further attention.
