The Study of Effectiveness of Chitosan from Pearl Oyster (Pinctada maxima) Shell as Antibacterial in Bone Scaffold Application
Get PDFChitosan is a functional material with potential for bone scaffolds due to its antibacterial properties, biocompatibility, biodegradability, low toxicity, and ability to support tissue regeneration and prevent infections in graft implantation.This study aims to identify changes in functional groups in each isolation process and identify the effect of chitosan concentration on the activity of Straphylococcus aureus and Escherichia coli bacteria. Chitosan isolation methods are demineralization, deproteination, decolorization, and deacetylation by microwave irradiation. Analysis of chitosan functional groups using FTIR, while antibacterial activity test using diffusion method. Isolation of chitosan from pearl oyster shells (Pinctada maxima sp.) obtained a degree of deacetylation of chitosan of 95.37%. Pearl oyster shell powder identified typical peaks of calcium carbonate (CaCO₃). The demineralized powder sample had calcium carbonate (CO₃²⁻) peaks that disappeared. Furthermore, the deproteinated powder sample produced peaks with amide groups (C=O dan N-H) of reduced protein. Decolorized powder samples did not show drastic changes in the bands of the deproteinated powder spectra, but the spectra could show cleaner and clearer peaks without any interference from pigments. The last, deacetylated powder sample showed a decrease in peak intensity in the 1650 cm⁻¹ (C=O amide). The analysis of the ability of chitosan to inhibit the growth of E. Coli and S. Aureus bacteria was effective at a minimum chitosan concentration of 20%. In comparison, antibacterial activity in S. aureus is better than in E. coli. Chitosan from this shell can serve as an antibacterial, but its manufacturing techniques need optimization for better efficacy

Development of Learner Activity Sheets Based on Guided Inquiry to Improve Student Learning Outcomes on Chemical Equilibrium Material
Get PDFEducation plays an important role in improving the quality of human resources. In the context of implementing the Merdeka Curriculum, teachers are given the freedom to design adaptive and contextual learning processes. Based on preliminary research findings, 50% of students reported difficulties in understanding chemical equilibrium material, with the main obstacles being unfamiliar terminology, excessive memorization, and complex calculations. To address these issues, this study aims to develop guided inquiry-based Learner Activity Sheets on chemical equilibrium material to improve the learning outcomes of class XI high school students. Chemistry learning, especially on the topic of chemical equilibrium, sub-material factors that affect the direction of chemical equilibrium shifts, is often considered abstract and difficult for students to understand, so learning media is needed that can facilitate critical thinking processes and conceptual understanding. Guided inquiry was chosen as a learning approach because it provides a balance between teacher direction and independent exploration by students. The research method used is Research and Development (R&D) with reference to the 4-D development model (Define, Design, Develop, and Disseminate) and limited to the Develop stage only. The population in this study was class XI of IPIEMS Surabaya High School. The results of Learner Activity Sheets validation from the three validators obtained a mode score of 5, which means that Learner Activity Sheets is feasible with very valid categories. The percentage of students' responses obtained was 96% which was declared practical. The learning outcomes of students are declared complete if they reach a score of ≥ 80. Based on the posttest results, the percentage of completeness is 88.5%. This percentage shows that classical completeness has been achieved, so it can be concluded that guided inquiry-based learning is effective in improving student learning outcomes

Antibacterial Activity of Probiotics from Naniura Made with Nile Tilapia (Oreochromis niloticus) against Salmonella typhi
Get PDFMicrobial contamination in foodstuffs, particularly by pathogenic bacteria such as Salmonella typhi, is one of the leading causes of foodborne diseases, posing a serious threat to public health. The use of antibiotics to control infections has led to an increase in antibiotic resistance cases, thereby necessitating safer and more sustainable alternatives for controlling pathogenic bacteria. One potential approach is the utilization of natural probiotics derived from traditional fermented foods. Naniura, a traditional dish from North Sumatra made from raw freshwater fish without any heating process, is believed to contain lactic acid bacteria (LAB) that function as probiotics. This study aims to evaluate the antibacterial activity of probiotics derived from naniura made with Nile tilapia (Oreochromis niloticus) against Salmonella typhi. Nile tilapia was selected due to its high protein content and meat structure with fewer bones compared to common carp. The fermentation of naniura was carried out for 10 hours to optimize the growth of probiotic microorganisms. Probiotic isolation was followed by macroscopic, microscopic, and biochemical characterizations using TSIA, citrate, motility, indole, ornithine, MRVP, catalase, amylolytic, and proteolytic activity tests. The antibacterial activity was evaluated using the disk diffusion method against Salmonella typhi. The results showed that the isolated probiotics exhibited morphological and physiological characteristics indicative of the genus Enterococcus, and the diameter of the inhibition zone produced is categorised as strong, with an average inhibition zone of 12.8 mm ± 0.36 against Salmonella typhi. This study demonstrates that naniura made from Nile tilapia has the potential to serve as a natural source of effective antibacterial probiotics
The Effectiveness of Guided Inquiry-Based Worksheet on Synthetic and Natural Food Colorant Thin Layer Chromatography Practicum in Developing Scientific Explanation Skills
Get PDFScientific explanation is an essential skill in chemistry learning because it connects scientific principles and objective evidence. This study aims to describe the application of guided inquiry-based learning in thin-layer chromatography experiments of synthetic and natural food coloring to develop students' scientific explanations in learning applications. This study used a pre-experimental method with a post-test only one-shot case study design. In the implementation of learning, the implementation rate reached 87%. The average scores for worksheets and scientific explanation tests were 78 and 79, respectively. This indicates that the application of guided inquiry-based worksheets through TLC experiments is practical in developing students' scientific explanation skills. This experiment can be adopted in broader chemistry learning contexts by integrating guided inquiry with thin-layer chromatography using real food colorants, thereby fostering scientific thinking and providing students with hands-on experience that emphasizes the relevance of chemistry in everyday life
Fauna Diversity and Bird Community Structure in the Bissoloro Educational Forest, South Sulawesi
Get PDFThe Bissoloro Educational Forest, covering an area of 75.12 hectares in Gowa Regency, South Sulawesi, serves as a natural research site under the stewardship of Muhammadiyah University of Makassar. Although the forest holds considerable ecological value, comprehensive and systematic data on its faunal diversity are still limited. This study was conducted to explore and evaluate the composition, richness, and community structure of fauna within the area, focusing on three major groups: mammals, reptiles, and birds. Data collection for mammals and reptiles was conducted through both direct sightings and indirect indicators, while avian data were obtained using a 1,700-meter line transect with 17 observation points over a three-day survey period. A total of 39 faunal species were recorded, comprising 4 mammal species, 10 reptile species, and 25 bird species. Among the bird species, Pycnonotus aurigaster was identified as the most dominant, with the highest Importance Value Index (INP) of 38.19%, supported by a relative frequency of 19.61% and relative dominance of 18.58%. The overall bird community diversity, as measured by the Shannon-Wiener index (H'), was 2.59, reflecting a moderate level of biodiversity. The occurrence of endemic and protected species, including top predators and nectar-feeding birds, indicates that essential ecological functions such as pollination and food web dynamics are still maintained. These results highlight the ecological importance of the Bissoloro Educational Forest and its role as a vital site for biodiversity conservation, environmental education, and long-term ecological monitoring in alignment with the Merdeka Belajar Kampus Merdeka (MBKM) framework
