ABSTRACT ? The aim of this research is improve biology learning quality for teacher performance, learning facilities, classroom climate, student?s science attitude in class, and student motivation of learning in student class XI Sains 5 SMA Negeri 7 Surakarta. The research is classroom action research. The steps of research include planning, acting, observing, and reflecting. The collecting data of research uses questionnaire, observation, and interview. The research uses triangulation as validation data. The research uses descriptive as analytic data. The acts of research contain three cycles. The result in cycles I, II and III describes that mean of observation data in the classroom for aspect teacher performance, classroom climate, student?s science attitude and students motivation in learning have been increase for every cycles and achieve of target ? 75% in cycles III, the utility of learning facilities in the classroom as well have been optimal. In addition, this research also uses interview and the result of interview shows that student motivation can improve after acts of research end, attitude of students can improve after act of research end, and conditioning of class can more interesting after acts of research end. The conclusion of research describes that the implementation of learning model cooperative type two stay two stray with media audio-visual can improve biology learning quality for teacher performance, learning facilities, classroom climate, student?s science attitude, and motivation of learning in student class XI Sains 5 SMA Negeri 7 Surakarta. Keywords: learning model cooperative type two stay two stray, media audio-visual, biology learning quality

The purpose of science learning is to master knowledge, understand and apply the concept of science, apply the skills of the science process and develop the attitude of science. Biology is a part of science, so to achieve the goal in the learning must be in accordance with the nature of science, namely science as a process, product, attitude, and application. Assessment of the achievement of knowledge competence is an assessment of students' intellectual/cognitive potential in biology learning, for which a valid and reliable assessment instrument is required. The assessment instrument reviewed here is a written test instrument. Written tests for measuring cognitive abilities can be distinguished into tests for measuring low-level cognitive abilities and measuring high-level cognitive abilities including analytical thinking skills. Analytical thinking skills is very important as a basis in solving problems faced by students especially in Biology learning. Therefore, teachers need to train students with problem-based learning solving and practice questions in the form of higher order thinking test. The form of higher order thinking test can be a choice test (chosen response test) that can measure analytical thinking skills in high school biology learning with respect to substantial aspects, constructs and language.

This research aims to develop a virtual laboratory Android application entitled "Bacterial Culture" as an innovative learning media in Microbiology courses. This application simulates the bacterial culture process, including media preparation, sterilization techniques, inoculation, and analysis of results. This research is a Research and Development (R&D) study using the Borg and Gall model which was adapted into six stages. The design validation stage includes validation of media and material experts, namely microbiology lecturers and small group trials involving third semester Biology Education students at IAIN Kudus. The results of expert validation by microbiology course lecturers show that this media obtained a validity score of 91.6% (very valid), and practicality testing by 3rd semester students obtained a score of 61.6% (Special). These findings indicate that the virtual laboratory "Bacterial Culture" is a learning medium that can support students' understanding of bacterial culture practicum before carrying out practicum in the laboratory. This study contributes to the progress of technology-based education which is aligned with the Independent Campus Learning Curriculum (MBKM).

Clitoria ternatea L. or telang flower is widely used as a natural food coloring, herbal tea and also as an additional active ingredient in pharmacological products. C. ternatea contains antioxidants are good for protecting cells from free radicals, maintaining the immune system, anti-aging and good for skin health. The aim of this research was to determine the gel formulation of C. ternatea flower extract regarding its total flavonoid content. The formulation results have gone through physical quality tests and total flavonoid tests. Physical quality test parameters include organoleptic test, homogeneity test, pH test, spreadability test, hedonic test, moisture test, and irritation test. The high extract content will increase the flavonoid content in the gel formulation, and it also make the color of the preparation more intense (purplish blue), making it less preferred by users. Therefore, from the hedonic test results, it is known that is preferred by users is with a concentration of C. ternatea condensed extract of 1%. The last formulation showed that the total flavonoid content of C. ternatea gel formulation had a total flavonoid content of 63.21 ug/g using UV-Vis spectrophotometry. This flavonoid content indicates that the gel formulation contains antioxidants are good for skin health.
