This study aims to develop a flash flipbook as learning media followed by testing its validity and reliability. The development model used is the ADDIE model (Analyze, Design, Development, Implementation, Evaluation) which is focused on the first 3 stages, namely Analyze, Design, and Development. Validation activities include instrument validation by 2 validators using the Guttman scale and media validation by 5 validators with 4 rating scales based on the Likert scale. Validation is done by filling out a closed questionnaire. Flash flipbook media validation assesses 3 aspects, namely aspects of format, content, and language. Analysis of the results of the flash flipbook validation using the Aiken's V method and the reliability test using the ICC (Intraclass Correlation Coefficient). This study shows that the validation results with the Aiken standard of 0.87 with 1 improvement and the ICC reliability results are 0.985 in the very good category. The addition of the literatures with the latest issue can increase the feasibility of this media. This flash flipbook can provide good visualization for students so as to provide variety in learning activities.

Bajakah Jie Xue Teng (Spatholobus suberectus) is an endemic plant from West Kalimantan which is the potential as a natural antimicrobial, but its antimicrobial ability has not been widely reported so that it can be tested on Micrococcus luteus bacteria which is the agent causing dandruff. The purpose of this study is to describe the phytochemical content of Jie Xue Teng (Spatholobus suberectus) bajakah ethanol extract and its potential to inhibit M. luteus in vitro. The phytochemical content of the extract was tested using the Thin Layer Chromatography (TLC) method. The type of research is a laboratory experiment using the Kirby Baeur disk diffusion method with swab technique with a series of extract concentrations of 1000 mg/ml, 500 mg/ml, 250 mg/ml, and 125 mg/ml, positive control (30% amoxilin), and negative control (DMSO 10%) with 4 repetitions. The phytochemical content of the ethanol extract of bajakah that was tested shows secondary metabolites of steroids, flavonoids, saponins, and alkaloids. Bajakah ethanol extract has the inhibitory potential against M. luteus for all test concentrations which fall under the moderate category. The diameter of the amoxicillin inhibition zone was still larger than the extract inhibition zone.
