Abstract

Soft coral Isis sp. is a type of soft coral that contains many chemical compounds with various benefits that have not been widely studied. This study aims to identify and isolate secondary metabolite compounds contained in the ethyl acetate extract fraction of Isis sp. soft coral, determine of antimicrobial activity, and molecular docking study. Compound separation was carried out by maceration followed by fractionation using Liquid Vacuum Chromatography (LVC). The fractions obtained were identified by Liquid Chromatography Tandem-Mass Spectrometry (LC-MS/MS) technique. Four compounds were successfully identified through LC-MS/MS analysis namely Deoxyadenosine (C10H13N5O3), Spinasterol (C29H48O), Pseudoionone (C11H16O) and Isosalsoline (C11H15NO2). Antimicrobial activity test was conducted against Staphylococcus aureus, and Escherichia coli. The results of the antimicrobial activity test showed strong activity against S.aureus bacteria and E. coli bacteria with the same MIC value of 2 µg/mL. Based on molecular docking analysis can be predicted that compounds isolated from soft coral Isis sp., namely pseudoinone compounds have a role as anti-bacterial S. aureus (PDB: 6KVS). This compound also shows a strong ability as an anti- gram positive bacteria than gram negative. Isosalsoline compounds have a role as anti-bacterial E. coli (PDB: 5BNM). This compound also shows a strong ability as an anti-gram negative bacteria rather than gram positive.

Abstract

This study presents a literature review on the use of the three-tier diagnostic test in identifying students’ misconceptions in chemistry and offers insights into its effectiveness in educational evaluation. A literature review of studies from 2019 to 2024 shows that 71.43% of these tests use close-ended questions due to their efficiency in terms of time, cost, and data analysis, compared to 28.57% that use open-ended questions. Research findings indicate that this test has successfully identified misconceptions in various chemistry topics, such as equilibrium, chemical bonding, ionization energy, and acids-bases. The ability of the three-tier diagnostic test to detect misconceptions makes it an effective tool for improving students’ conceptual understanding. The findings indicate that the three-tier diagnostic test has been widely used to uncover students’ conceptual difficulties across various chemistry topics. Its use has shown promise in supporting more accurate and in-depth assessments compared to traditional evaluation methods. The review suggests that this type of diagnostic testing can enhance the quality of formative assessments and contribute to improved instructional planning.

Abstract

Soy milk kefir offers a plant-based alternative to dairy probiotics. This study aimed to enhance both the chemical and functional characteristics of soy milk kefir by evaluating the effects of varying kefir grain starter doses and added Clitoria ternatea (telang) flower juice. A 3x4 factorial design was employed using three starter levels (40g, 50g, 60g per liter soy milk) and four telang juice concentrations (0ml, 10ml, 20ml, 30ml per liter). Key parameters analyzed post-fermentation included protein content (Kjeldahl), lactic acid (titration), pH, Water Holding Capacity (WHC, centrifugation), anthocyanin content (differential pH method), and Lactic Acid Bacteria (LAB) count (plate count). Results indicated significant (p<0.05) effects of both starter dose and telang juice concentration, and their interaction, on all measured characteristics. Specifically, the 40g starter + 30ml juice treatment yielded the highest protein (39.35%) and anthocyanin (18.42 mg/mL). The 50g starter + 20ml juice treatment showed the highest WHC (67.30%). The 60g starter + 30ml juice treatment produced the highest lactic acid (20.30%). Higher LAB counts were observed in several treatments including A0B0, A1B1, A2B2, and A2B3 compared to others. In conclusion, optimizing kefir grain dosage and adding telang flower juice significantly improves soy milk kefir's nutritional profile (protein) and functional attributes (anthocyanins, WHC, LAB), demonstrating its potential as an enhanced plant-based functional food.
