Abstract

This study aims to determine the effect of Colocasia esculenta L on the growth and motility of zebrafish (Danio rerio) larvae after induction of rotenone as a stunting model. The Zebrafish have divided 3 groups i.e Normal (embryonic medium without rotenone induction), Negative Control (embryonic medium with rotenone induction), and Treatment Groups (embryonic medium with rotenone induction and Colocasia esculenta extracts, dose 30-60-90 ppm). The stunting model is designed by induction of 12.5 ppb rotenone to Zebrafish larvae. The growth of the larvae was observed by using a microscope to measure the body and head length. Evaluation of motility was carried out by recording the movement of the fish for 1 minute, and the pace was analyzed by using Video Tracker. The evaluations were observed at 3, 6, 9 dpf (day post-fertilization). Colocasia Esculenta Extract (CEE) groups have higher body lengths compared to the Negative Control Group. The lengths were 125.4 µm for CEE30, 119.4 µm for CEE60, and 121.4 µm CEE90 while the length for the Negative Control Group was 118.3 µm at 9 dpf. However, there were no different values for the ratio of head length to body length of all groups. The ratio was 1:6 at 3 dpf, and 1:4 at 6 and 9 dpf. Moreover, the motility was higher in CEE groups compared to the Negative Control at 3, 6, 9 dpf. The body length and motility of Zebrafish larvae higher compare to the Negative Control Group showing the potential of Colocasia esculenta extract on growth and enhancement of motoric activity.

Abstract

The purpose of this study was to investigate the effect of project-based learning models on students' learning activities and outcomes. This research employed a quasi-experimental design with a pretest-posttest control group. The study was conducted from July to August 2022 at SMA Negeri 12 Makassar. The population consisted of 10th-grade students in the science program, totaling 7 classes. Random sampling selected X MIA 4 as the experimental group and X MIA 2 as the control group. Observational sheets were used to monitor student activities, while test instruments were used to assess student learning outcomes. Data collected were analyzed using descriptive statistics and inferential statistical analysis through Statistical Package for Social Science (SPSS) Version 23.0. Analysis of pretest and posttest scores from the experimental group, comprising 34 students, revealed that 5 students achieved a score in the 'very good' category and 9 students in the 'good' category. In contrast, the control group did not have any students in the 'very good' category; only 3 students were in the 'good' category. Observational results from three observers in the experimental group indicated that 96.73% of students were 'highly active', whereas in the control group, 67.07% were 'sufficiently active'. In conclusion, the research findings suggest that the project-based learning model influences students' learning activities and outcomes.

Abstract

The new policies included in the independent curriculum certainly have several different aspects. One of the differences here is in the teaching tools. In the independent curriculum, the Learning Implementation Plan (RPP) is referred to as a teaching module. Teachers can choose or even modify their own teaching modules that have been provided by the central government. Teachers need to develop teaching modules, but in reality there are still many teachers who experience difficulties in developing teaching modules. This research aims to determine the difficulties experienced by high school biology teachers in developing teaching modules. This study used qualitative research methods. The research subjects taken were the population of class X and XI Biology teachers at SMA Negeri 2 Temanggung, SMA Negeri 1 Candiroto, and SMA Negeri 1 Pringsurat. Data collection techniques used in research include observation, interviews and questionnaires. The research results show that the difficulty of Biology teachers in developing teaching modules is 45%. The level of difficulty is found in indicators of analysis and mapping of student needs, determining the dimensions of the Pancasila student profile, clarity of learning objectives, organizing teaching materials, determining learning models, determining and carrying out assessments, evaluating learning and following up on teaching modules, as well as difficulties in analyzing learning outcomes. will be reduced to a teaching module. The factors that make it difficult for Biology teachers to develop teaching modules are: 1) the number of students; 2) difficulty reading Learning Outcomes (CP); 3) the material is very short and unsystematic; 4) time constraints; 5) minimal reference for the implementation of the assessment; and 6) level of technological mastery. Thus, it can be concluded that the difficulties of high school biology teachers in developing teaching modules in the independent curriculum at Temanggung driving schools are in the "sufficient" category.

Abstract

The way of life back to nature, including in the field of health, forms the habit of using plants as traditional medicine. Traditional medicine is indicated to be able to cure a variety of diseases. As with the leaves of Ciplukan (Physalis peruviana L.) by the people of Desa Wanasuka Kecamatan Pangalengan Kabupaten Bandung is considered to be used as a traditional medicine for inflammatory diseases such as rheumatism, asthma, and gastritis (maag) due to side effects and toxicity produced relatively small when compared with modern medicine. The aim of this study is to identify the potential of the secondary metabolite compound found in the leaves of the Ciplulan (Physalis peruviana L.) as a candidate for anti-inflammatory drugs. These research methods are molecular methods of docking through physical chemical properties testing, pharmacokinetic profiles of test compounds through site Pre-ADMET (Absorption, distribution, metabolism, excretion, and toxicity) and Lipinski Rule of Five. The results of this study showed that the binding affinity of caffeic acid compounds with PTGS2 receptors (PDB ID: 5F19) showed a more negative result compared to the comparative drugs Aspirin and Ibuprofen -7.4. There was a molecular interaction similar to Aspirin, in which the addition of amino acid residues from ASN 382 and TYR 385 produces a strong irreversible inhibition of PTGS2 (PDB ID: 5F19) and is predicted to inhibit prostaglandin H synthase and indicate that caffeic acid is capable of producing irreverible inactivation of PTGS2 (PDB ID:5F19). So potentially a candidate for a safer anti inflammatory drug for the body. Because it has almost the same or close potential as Aspirin against inflammatory diseases.

Abstract

Staphylococcus epidermidis is a gram-positive bacterium that can cause acne. It is part of the normal flora found on the skin and is non-pathogenic. Metabolite compounds such as tannins, saponins, triterpenoids, and flavonoids present in starfruit leaves and castor leaves have antibiotic properties. The aim of this study was to determine the effectiveness of the combination of starfruit leaf extract and castor leaf extract, and to identify the most effective concentration ratio of these extracts in inhibiting Staphylococcus epidermidis bacteria. The research method used was experimental, conducting in-vitro antibacterial activity tests against Staphylococcus epidermidis. The results of the antibacterial test using a combination of starfruit leaf extract and castor leaf extract showed that at the highest ratio of 1:3, it produced an average inhibition zone of 15.73 mm against Staphylococcus epidermidis bacteria. This result was higher compared to the positive control Clindamycin HCl.

Abstract

Teluk Nibung River in Batu Ampar District, Kubu Raya Regency is a transportation route for Mangrove Production Forests and a traditional fishing area for local communities. The community structure of phytoplankton in the Teluk Nibung River has never been reported. As the main producer in the waters food chain, the structure community of phytoplankton indicates the quality of the fertility of the waters. The community structure of phytoplankton can be identified by measuring the index of abundance, diversity, evenness and dominance. The survey method was used at three stations in dry and rainy seasons. Sample collection is using net plankton (30 µm) and preserved in 4% formalin. The physico-chemical factors measured included temperature, pH, brightness, current velocity, salinity, dissolved oxygen and CO2, phosphate and nitrate. Once identified, phytoplankton calculations are performed to obtain abundance, diversity, evenness, and dominance values. The species number of phytoplankton found was 56 classified into 6 classes, namely Bacillariophyceae (34 species), Dinophyceae (12 species), Chlorophyceae (4 species), Cyanophyceae (3 species), Xantophyceae (1 species), and Euglenophyceae (2 species). The highest abundance of phytoplankton was in the Bacillariophyceae class with a range of 583 Ind./L at Station 2 in the rainy season to 3.922 Ind./L at Station 3 in the dry season. The diversity index at the three stations and both seasons is in the moderate category with a range of 2.31-2.46. The evenness index at the three stations and both seasons is in the high category with a range of 0.67-0.73. Low dominance level was found at the three stations and both seasons with values ranging from 0.14 to 0.19. Overall, the community structure of the phytoplankton in the Teluk Nibung River is in relatively good condition and can support the life of the aquatic biota in it.

Abstract

Indonesia continues to be committed to improving the quality of human resources. This is realized through the Ministry of Education and Culture, which promotes and implements a curriculum that supports learning freedom. The application of this curriculum requires not only theoretical support but also more practical technical support, which cannot be ignored. In this regard, the Mandalika University of Education, especially the biology education department, has held workshops related to technical guidance for implementing the freedom to learn curriculum. However, it is essential to understand that there needs to be more information regarding the readiness of prospective biology teacher students to implement this curriculum. Therefore, this research was conducted to describe the level of readiness of prospective biology teacher students for independent learning. In this research, 53 prospective teacher students were involved voluntarily as respondents, including 42 women and 11 men, consisting of 12 (semester 1), 15 (semester 3), 17 (semester 5), and 9 (semester 7). The instrument used to measure the level of readiness for independent learning was adapted from the self-rating scale of self-directed learning (SRSSDL) questionnaire. Next, data regarding readiness for independent learning was analyzed descriptively and quantitatively. Based on the results of the analysis, it was found that 16.98% were not very ready (low or unprepared), 73.58% were not ready (moderate), and 9.43% were ready (high). These results also show that prospective biology teacher students have the same level of readiness for independent learning or that there is no significant difference in readiness for independent learning based on semester differences. Apart from that, of the SRSSDL components, self-awareness and learning activities have the lowest averages (32.51 and 32.09). Thus, our respondents (in this case, prospective biology teacher students) are not ready for independent learning. Regarding what will be done next, can be seen in the conclusions and recommendations section.
