Abstract

Streptococcus mutans is a major species that causes dental caries due to its acidogenic and aciduric properties. Coffee beans contain several compounds, such as caffeine, phenols, tannins, trigonelline, chlorogenic acid, and caffeic acid, which are known for their antibacterial properties. Robusta instant coffee powder is a stable product that is not easily contaminated with bacteria, fungi, and yeast. It is a zero-waste and soluble material. This study aimed to analyze the antibacterial activity of robusta instant coffee powder (RICP) against S. mutans. The antibacterial activity of RICP against S. mutans was tested using three antimicrobial susceptibility tests: 1) disk diffusion method, 2) minimum inhibitory concentrations (MIC), and 3) minimum bactericidal concentration (MBC). The results of the disk diffusion method test showed that the RICP concentration of 0.2 g/mL to 0.8 g/mL against S. mutans had an inhibition zone of 31.14 mm to 42.01 mm. MIC and MBC values of RICP against S. mutans were both 0.0313 g/mL. In conclusion, robusta instant coffee powder (RICP) demonstrates antibacterial activity against the acidogenic and aciduric S. mutans bacteria.

Abstract

Yogurt is one of the fermented dairy products produced by lactic acid bacteria from milk, which contains beneficial nutritional components for human health. The innovation of yogurt production with the addition of probiotic cultures and food ingredients containing bioactive compounds can enhance its quality. This research aims to investigate the effect of adding purple sweet potato extract and storage treatment at 4℃ on yogurt's antioxidant and antibacterial activities. Four treatments were conducted in yogurt production, namely without adding purple sweet potato extract and adding 5%, 10%, and 15% (v/v) extract. All treatments were fermented using Lactobacillus bulgaricus, Streptococcus thermophilus, and Lactobacillus plantarum S1K2T1 as starter cultures. Subsequently, the yogurt was stored at 4℃ for 6 days, and chemical parameters, antioxidant, and antibacterial activities were examined. The highest result was observed in the treatment with 15% addition, showing a total antioxidant activity of 70.98% and an IC50 value of 13.96 ppm, which is equivalent to 2.06 times that of 200 ppm ascorbic acid. The six days storage affected antioxidant activity, but it was not significantly different. The antibacterial test showed indications of inhibition against Staphylococcus aureus ATCC 25923, Salmonella typhi NCTC 786, and Escherichia coli ATCC 25922, although the effect was very weak.

Abstract

One of the global problems that often occurs in society is environmental pollution, one of which is water pollution. The impact of water pollution is in the form of ecosystem damage and decreased water quality. One of nature's efforts to prevent environmental pollution in waters is by having bioindicators in waters, one of which is microalgae. However, if the community is less sensitive to environmental sustainability, environmental pollution will continue to occur. Therefore, public awareness is needed to protect the environment, one way is to foster an attitude of environmental concern among high school students by creating teaching materials related to the environment. To make it easier for students to understand and use the teaching materials, teaching materials were made in the form of PBL-based electronic modules that integrate materials related to microalgae and water quality to improve the environmental concern of class X high school students in a valid, practical and effective manner. The subjects used in this study were four classes of class X students of SMAN 12 Makassar. The instrument used in this study was an environmental concern attitude questionnaire that had been validated by experts. The results of this study can be categorized as valid, practical and effective because the validity results obtained 100% from the material expert validator, 92.2% from media and teaching materials experts, and 89.3 from biology education practitioners. While for the practicality test, there are 3 categories, namely, for individual tests the results were 86.58%, small group tests of 87.42%, and field tests of 87.44%. The effectiveness test is divided into 5 tests, namely, normality test, homogeneity test, N gain test, T test and ANCOVA test, where all tests obtained the results of the electronic module effectively used as teaching materials for class X of high school. This shows that the electronic module has an influence on the environmental care attitude of high school students in class X.

Abstract

The 21st century is recognized as the age of knowledge, marked by technological advancements, where students are expected to possess strong critical thinking skills. However, in the realm of science education, students' attitudes towards critical thinking remain relatively low. This is primarily due to the passive reception of information, with students merely memorizing it for examinations or tests. Thus, there is a pressing need for solutions to address these challenges. This research aims to determine the effectiveness of the Cloud-assisted PjBL model on students' critical thinking skills on the topic of Environmental Pollution. The method used was a quasi-experimental. The research instruments were a test for critical thinking skills, a questionnaire for environmental care attitudes, and for the Cloud-assisted PjBL learning response questionnaire. The outcomes indicated that the N-Gain data for the experimental class yielded a value of 0.75, indicating a high category, while the control class obtained a value of 0.49, indicating a medium category. The average result for environmental care attitudes among students in the experimental and control class is good. The conclusion in this research is that the Cloud-assisted PjBL model is effective on students' critical thinking skills and can improve students' environmental care attitudes.
