Abstract

Black rice is an alternative staple food better than white rice. It has lower carbs, but higher antocyanin compared to white rice. Nowadays, black rice consumption has increased, production needs to be increased to accomodate the demand. But, to our knowledge, there is lack of information about black rice resistance against biotic stresses, one of black rice cultivar is Cempo Ireng. This information needed for optimal Cempo Ireng cultivation. In this research, we determined chlorophyl content and analyzed OsNPR1 expression of three cultivars: Java14 (resistant control), Cempo Ireng, and IR64 (susceptible control), against Xanthomonas oryzae (Xoo). All of them were sprayed with salicylic acid (SA) before inoculated with Xoo. IR64 24h had the lowest chlorophyll content (0,576 ± 0,066 mg/g), meanwhile Java14 72h had the highest content (2,358 ± 1,301 mg/g). However, all the cultivars did not show any correlation between them and time after Xoo inoculation. OsNPR1 expression did not show any significant change in Java14 and Cempo Ireng after being inoculation. However, IR64 showed increasing OsNPR1 in 72h and did not change in 96h after inoculation. It indicated that OsNPR1 played important role in IR64 resistance against Xoo, but not in Cempo Ireng and Java14.

Abstract

Kegiatan Pendampingan Pengembangan Media Pembelajaran Inovatif berbasis AI bagi mahasiswa calon guru di STKIP Kumala Lampung Metro bertujuan membekali mahasiswa dengan keterampilan merancang media pembelajaran kreatif dan efektif yang relevan di era digital. Program ini mendukung kesiapan mahasiswa menghadapi tantangan pendidikan modern serta sebagai bekal kegiatan PPLT. Metode pelaksanaan meliputi observasi awal, pemaparan materi, sesi praktik langsung menggunakan aplikasi berbasis AI seperti Canva, ChatGPT, Kahoot, dan Quizizz, serta evaluasi melalui angket kepuasan peserta. Hasil kegiatan menunjukkan peningkatan pemahaman mahasiswa dalam memanfaatkan teknologi AI untuk pengembangan media pembelajaran interaktif. Berdasarkan umpan balik, 85% peserta menilai materi sangat relevan dan aplikatif, sedangkan 90% menyatakan puas dengan keseluruhan kegiatan. Diskusi dan simulasi pembelajaran membantu peserta memperbaiki media yang mereka kembangkan. Program ini berhasil meningkatkan keterampilan mahasiswa dalam memadukan teknologi dan kreativitas, dengan harapan mampu mendukung pembelajaran yang lebih inovatif dan bermakna.
