Penyakit yang menyerang buah jeruk dapat disebabkan oleh serangan mikroorganisme berupa bakteri atau cendawan. Tujuan penelitian ini adalah mengisolasi, mengidentifikasi, dan mengkarakterisasi serta mengetahui insidensi dan keparahan penyakit dari mikroorganisme penyebab nekrosis pada jeruk siam (Citrus nobilis Lour.). Metode yang digunakan adalah deskriptif kualitatif. Hasil penelitian menunjukkan bahwa isolat mikroorganisme yang diperoleh dari buah jeruk siam (Citrus nobilis Lour.) bergejala nekrosis adalah bakteri isolat CBN-1 dengan bentuk bacil berlendir, circular, berwarna putih, tepi entire, elevasi low convex, dan struktur dalam smooth. CBN-1 dapat menginfeksi buah jeruk siam (Citrus nobilis Lour.) dengan patogenitas berupa insidensi penyakit 100%, keparahan penyakit 50%, laju infeksi 9%, dan AUPDC 1,75.

Abstract

This study aims to develop video-based Arabic reading learning media at Al-Azhar Islamic High School Kelapa Gading Jakarta. The research method used is development research with the ADDIE model. The subject of the study was a grade XI student of Al-Azhar Islamic High School Kelapa Gading Jakarta. Development research with the ADDIE model has five stages of research, namely: Analyze, researchers analyze student needs for the development of video-based learning media; Design, researchers collect material and design media to be developed; Development, researchers carry out the process of developing video-based learning media; Implementation, testing products that have been developed; and Evaluation, evaluating activities to determine the quality of media products that have been developed. The results of the material expert assessment get a percentage of 86.67% with the very decent category and the results of the media expert assessment get a percentage of 90.58% with the very decent category and the results of student assessment and evaluation get a percentage of 85.12% with the very decent category.  Based on the assessment above, video-based learning media is suitable to be used as an Arabic learning medium, especially in reading Arabic.
