Online learning during the Covid-19 pandemic is an alternative even though it runs with limitations. Collaboration skills in online learning have not been optimally empowered, which is an urgency to be developed in order to prevent individualistic life and train social character. This research is a quantitative descriptive study aimed at analyzing differences in student collaboration skills before and after learning using the Problem-based Learning model through Lesson Study activities. The research population is Biology Department students who program the Plant Physiology course in the odd semester of the 2021/2022 academic year with a sample size of 32 students. Collaboration skills are measured through observation by paying attention to the assessment rubric adapted from Greenstein including indicators of working productively, showing respect, compromising, and being responsible for contributing. Data analysis used paired sample t-test. A significance value was obtained of 0.000 <0.05, which means that there was a significant difference between the initial collaboration and the final collaboration of students. The Problem-based Learning learning model through Lesson Study activities effectively improves student collaboration skills.

“…Kandungan fruktosa dan glukosa mencapai 85% hingga 90% berasal dari karbohidrat yang terkandung dalam madu serta hanya sebagian kecil dalam bentuk oligosakarida dan polisakarida (Feronica, 2012). Kandungan madu lain diantaranya adalah berupa berbagai enzim yaitu enzim invertase, enzim glukosa oksidase, peroksidase, dan lipase (Ariandi & Khaerati, 2017).…”

UJI DAYA HAMBAT MADU HUTAN BADUY SEBAGAI SUBSTRAT PADA BUNGA TELANG (Clitoria ternatea L) MELALUI METODE BIOTEKNOLOGI FERMENTASI KOMBUCHA DALAM MENGHAMBAT PERTUMBUHAN BAKTERI PATOGEN

Telang flower (Clitoria ternatea L) fermented by kombucha is a probiotic drink produced by a consortium of bacteria and yeast. The raw material in this kombucha fermentation is in the form of telang flowers that have been cold from the previous boiling process. This study aims to determine the antibacterial activity of telang flower kombucha with different concentrations of Baduy forest honey. The concentration of Baduy forest honey consisted of 20%, 30%, and 40% (w/v) where each treatment was repeated 3 times. The positive control used in this study was kombucha made from green tea. Sterile aquadest is a treatment positioned as a negative control. The disc diffusion method is one of the methods used in antibacterial testing by measuring the diameter of the inhibition zone. Telang flower kombucha fermentation has activity as a broad-spectrum antibacterial source. This can be indicated by the potential to prevent the growth of Staphylococcus aureus, Staphylococcus epidermidis, Pseudomnonas aeruginosa, and Escherichia coli bacteria. Baduy forest honey concentration of 40% is the best concentration in fermented kombucha flower telang as an antibacterial and has the potential as the latest functional drink from fermented biotechnology products.

This study aimed to determine the quality of defective honey, bitter honey, and sweet honey produced by the Baduy community. The bitter honey was collected from locations where nectar was sourced from calliandra, mahogany, sengon, and kamboja trees. The sweet honey was collected from locations where nectar was sourced from fruit trees such as bananas, sugar palm, durian, jackfruit, and rambutan. The defective honey is sweet honey that produces gas and therefore it is bubbly and considered to be damaged by the Baduy community. The research applied the criteria of the Indonesian National Standard SNI 8664 (2018) to test the quality of honey. The results showed that defective honey fulfills five criteria, i.e.: HMF testing, ash content, insoluble solids in water, acidity, smell, and taste. Bitter honey fulfilled four criteria, i.e., testing of ash content, water-insoluble solids, acidity, and moisture content. Sweet honey fulfilled seven criteria, i.e., the testing of ash content, sucrose, water-insoluble solids, acidity, moisture content, odor, and taste. All types of honey did not meet the criteria of diastase enzyme activity and reducing sugar levels. This could be due to conditions and storage time of honey before testing.
