Abstract

This study aimed to investigate the implementation of Webquest in a blended EFL (English as Foreign Language) learning context and the students’ speaking skills improvement dealing with it. A number of 21 students were involved in the classroom action research designed. This classroom action research focused on two pedagogical issues of the methodology as well as the students’ improvement of their speaking skills. The lesson plan including the test instruments was prepared in line with the proposed teaching model. To begin, the observation supported with field notes was executed to describe the teaching and learning process. We played the role of passive participant in this period. Subsequently, the students’ speaking skills were evaluated through oral test in which the results of pre-cycle test as well as after-cycles were analyzed using t-test. We found that there was a significant improvement on the students’ speaking skills in term of pronunciation, intonation, fluency, grammar and vocabulary within two cycles of action research. Thus, the implementation of Webquest as media in blended learning was successful to improve the students’ speaking skills.

Abstract

Minyak kayu manis diperoleh dengan cara distilasi dari kulit batang kayu manis. Komponen utama dalam minyak kayu manis adalah sinamaldehid (42-75%). Sinamaldehid merupakan senyawa yang memiliki gugus aldehid yang dapat dimodifikasi menjadi gugus ester yang dapat digunakan sebagai antidiabetes. Tujuan penelitian ini adalah mensintesis etil sinamat dari asam sinamat dan menguji aktivitas etil sinamat sebagai antidiabetes. Metode dari penelitian ini adalah oksidasi dan esterifikasi. Etil sinamat diperoleh dari hasil sintesis merupakan cairan berwarna kuning jernih dan berbau harum dengan rendemen sebesar 98,86%. Hasil dari FTIR menunjukkan terbentuknya etil sinamat dengan adanya gugus C-O ester, sedangkan dari hasil GC-MS diperoleh kelimpahan etil sinamat sebesar 99,01%. Hasil uji aktivitas antidiabetes menunjukkan bahwa, senyawa etil sinamat memiliki nilai IC50 sebesar 215,509 ppm.   Keywords: sintesis; oksidasi; esterifikasi; sinamaldehid; antidiabetes.

Abstract

Cinnamon oil is obtained by distillation from the bark of cinnamon. The main component in cinnamon oil is cynnamaldehyde (42-75%). Cynnamaldehyde is a compounds which has aldehyde group that can be modified into the ester group that can be used as an antidiabetic. The synthesis cinnamic esters was oxidation and esterification. This research aims to isolate cynnamaldehyde of cinnamon oil, synthesized cinnamic acid and activities test as antidiabetic. Ethyl cinnamic is obtained from the synthesis of a clear yellow liquid and fragrant with a yield 98.86%. The results of FTIR showed the formation of cinnamic ethyl ester in the presence of CO groups, where as the results obtained by GC-MS abudance of 99.01% ethyl cinnamate. From the antidiabetic test results, ethyl cinnamate coumpounds IC50 values of 215.509 ppm.

Abstract

This study aims to examine the effect of profitability, liquidity, and leverage on the disclosure of Islamic social reporting, with firm size as a moderating variable, in the pharmaceutical sub-sector companies listed on the Indonesian Sharia Stock Index (ISSI) for the 2017–2020 period. The analytical method used in this research is data regression analysis, which is then measured using the Eviews 12 test tool. Through the model feasibility test, this study uses the random effect model as the best model in the study. The results showed that before using the moderating variable, profitability had a negative influence on Islamic social reporting disclosure, and after using the moderating variable, profitability had a positive influence. Meanwhile, the liquidity variable had no effect on the disclosure of Islamic social reporting, either before or after using the moderating variable. Then the leverage variable, before using the moderating variable, had a positive effect on the disclosure of Islamic social reporting, and after using the moderating variable, it had a negative effect on the disclosure of Islamic social reporting.

Abstract

Setiap lima tahun sekali pemilik kendaraan bermotor yang disebut wajib pajak melakukan proses ganti NRKB (Nomor Registrasi Kendaraan Bermotor). Kurangnya pemahaman pengetahuan alur ganti NRKB membuat masyarakat kerap kali kebingungan. Banyak terjadi kesalahan alur prosedur dikarenakan jarangnya membaca petunjuk alur proses di ruang informasi sehingga proses yang dilakukan memakan waktu lebih lama. Tujuan pembuatan aplikasi Proses Ganti NRKB Kendaraan Bermotor berbasis Augmented Reality (AR) sebagai media informasi yang lebih menarik serta interaktif kepada wajib pajak untuk mengenali alur proses ganti NRKB di Samsat setempat. Augmented Reality  merupakan gabungan teknologi benda maya dua dan tiga dimensi untuk diproyeksikan ke dalam dunia nyata. Masyarakat dapat berinteraksi langsung dengan aplikasi AR, melalui media informasi ini alur ganti NRKB dikemas lebih menarik dan mudah dimengerti. Aplikasi yang dibangun menampilkan objek virtual 3D secara realtime pada perangkat mobile android. Metode yang digunakan dalam penelitian aplikasi ini ialah MDLC. Proses pembuatan aplikasi AR diawali dengan pengumpulkan data tentang alur proses ganti NRKB kendaraan bermotor yang selanjutnya dibuat sebagai model menggunakan software 3D Blender. Aplikasi Augmented Reality dirancangan menggunakan software Unity. Berdasarkan hasil pengujian aplikasi dengan metode black box aplikasi dinyatakan bekerja dengan baik pada mobile platform android 11, berdasarkan hasil kuesioner dengan metode skala likert sebanyak 30 responden diperoleh presentase 80% menyatakan AR yang dibangun masuk dalam interval score sangat baik. Menunjukkan AR yang dibangun memberikan kemudahan pada wajib pajak untuk mengetahui informasi tentang alur ganti NRKB. Maka disimpulkan aplikasi implementasi Augmented Reality untuk alur proses ganti NRKB kendaraan bermotor ini dapat berjalan dengan sangat baik.
