Cinnamaldehyde is the main component of cinnamon oil (78 %) containing of aldehyde group which can be modified into the ester group is expected to be potentially as an antidiabetic. The purpose of this research was to isolate cinnamaldehyde from cinnamon oil, cinnamaldehyde oxidation became cinnamic acid, butyl cinnamate synthesis from cinnamic acid and activities test of butyl cinnamate as an antidiabetic. The method of this research was oxidation and esterification. Butyl cinnamate obtained from the synthesis is orange-yellowish liquid and fragrant smell with it’s yield as big as 97,79 %. The result of FTIR shows that it has been formed butyl cinnamate with absorption of ester (C-O), whereas the results obtained by GC-MS is an abundance of butyl cinnamate as big as 100 %. The result of the antidiabetic test, butyl cinnamate have IC50 value as big as 120,951 ppm.

Teknik pengumpulan data melalui angket, dokumentasi (media pembelajaran online), dan wawancara dianalisis menggunakan metode deskriptif kualitatif. Hasil penelitian menunjukkan bahwa kompetensi dan pemahaman guru muda lebih siap menghadapi tantangan pembelajaran daring dibandingkan dengan guru yang lebih senior. Media aplikasi daring pun bermacam-macam. Penelitian selanjutnya membutuhkan analisis mendalam tentang apakah interaksi akademik dapat mempengaruhi siswa dan guru secara psikologis dan membantu meningkatkan prestasi belajar siswa.

Abstract

The study was aimed to discover the form of comics used in language learning and the development process, as well as the style of the Comic suitable with the interest of Japanese language students used in the previous study, which is expected to elaborate types of necessary research in the future for Japanese language teaching material development. There were 20 articles reviewed related to comics development for language learning. Based on the review result, it was found that 1) There are two types of comics, namely 1-Panel Comic used to explain one specific material and 4-Panel Comic used for conversation materials. However, there has yet any research related to comics development in the form of comic books; 2) In terms of process, both types of comics are formulated and developed by referring to a curriculum and learning plan so that the comics may assist students in understanding learning material; 3) Comic styles discussed in previous researches refer to American comic style, and thus less suitable to be used as Japanese language learning materials. The style used in Japanese comics is predicted to be more attractive for Japanese language students. However, there has yet any scientific study on the development of Japanese style comics in Japanese language learning.

Abstract

Classroom Action Research (CAR) facilitates teachers to improve the quality of learning and teaching and works with them to develop and understand engaging context-specific research. In this study, 193 Japanese language teachers’ perceptions of CAR were qualitatively explored through Classroom Action Research’s survey to know the Japanese language teachers’ perceptions and abilities of research, especially at the high school level. A questionnaire consisting of open-ended questions was utilized to collect the data. The results revealed that most teachers don’t have sufficient capacity and ability to do the research, but they considered that research is a crucial skill. Participants who have done CAR mostly use it for getting promoted, and only a few of them use it to develop the quality of teaching. The survey results also showed that many teachers never did CAR based on the structured way or never done it at all. This study reveals that the ability of the teachers to do the research needs to be improved extensively.
