Abstract

AbstractThis research was applied research that aim to apply flipped learning of Microbiology material integrated with the Learning Management System in online lectures during the Covid 19 Pandemic. This research is applied to the Human Health Science course, both class A and class B, which is attended by 80 Biology Education Study Program students. 2019 and held from August to October 2020 in the Biology Education Study Program at Sanata Dharma University. The step of implementing flipped learning begins with preparing RPS, video explanation of lecture material using o-matic screencast, journal, virtual lab, practicum simulation video using filmix, quiz using quizizz, and assessment rubric. Furthermore, the material and media are linked to Moodle (belajar.usd.ac.id). The data analyzed in this study included assignment scores, quizzes, and online lecture evaluation results. The results of the research obtained were the value of the assignment in the form of analysis of 3 microbiology journals, the mean score for class A was 81.4 and class B was 71.7, while the average quiz score for class A was 79.2 and class B was 76.6. The results of the overall learning evaluation class A 3,4, while class B 3.5. The application of flipped learning on the integrated Microbiology Learning Management System material based on the results of the evaluation of learning is categorized as very good.Keywords: flipped learning, microbiology, learning management system

Abstract

One alternative biofuel to substitute fossil fuels is bioethanol. Microalgae Spirulina sp. contains high carbohydrates, which has 17-25% potential to produce bioethanol. Urea and NaHCO3 can be used as additional nutrients sources of nitrogen and carbon to Spirulina sp. cultivation. Deficiency of nitrogen causing the cell’s enzymes change that shown through decreased lipid and chlorophyll synthesis. While deficiency of carbon can affect the growth rate. In this research, the growth rate of Spirulina sp. is analyzed using Optical Density (OD) method. The growth rate calculation is used to measure the growth of microalgae cells shown in the growth curve. This was a laboratory-scale method using CRD with 4 treatments and 5 replications namely treatment A addition of 0.36 g/500 ml urea without addition of NaHCO3, treatment B addition of 0.043 g/500 ml NaHCO3 without addition of urea, treatment C addition of 0.36 g/500 ml urea and 0.043 g/500 ml NaHCO3, and control without addition of urea or NaHCO3. The results indicated that addition of urea and NaHCO3 didn’t affect to OD and Spirulina sp. growth rate. The highest growth rate was treatment A with 0.00906/day of growth rate followed by treatment C which has 0.00865/day of growth rate. Treatment B and control treatment (K) showed a low growth rate. The maximum OD value obtained in treatment C was 0.674 cells/ml on the 10th day. This research can be used as the reference to larger scale of Spirulina sp. cultivation in the field of bioethanol production.
