Abstract

Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan pengetahuan dan keterampilan warga Desa Perumnas Simalingkar, Kecamatan Pancur Batu, Kabupaten Deli Serdang, dalam hal pemeliharaan tanaman bunga hias sebagai upaya pemberdayaan ekonomi berbasis rumah tangga sekaligus pelestarian lingkungan. Latar belakang kegiatan ini berangkat dari potensi besar yang dimiliki oleh desa tersebut, yaitu kondisi iklim dan geografis yang mendukung pertumbuhan tanaman hias, namun belum dimanfaatkan secara optimal oleh masyarakat karena keterbatasan informasi dan keterampilan teknis. Kegiatan ini diikuti oleh Ibu PKK yang merupakan warga desa perumnas simalingkar kecamatan pancur batu kabupaten deli serdang. Hasil dari kegiatan ini menunjukkan bahwa peserta mengalami peningkatan pemahaman yang signifikan terhadap aspek teknis pemeliharaan bunga hias, yang diukur melalui pre-test dan post-test sederhana. Selain itu, peserta menunjukkan antusiasme untuk mulai menanam dan merawat bunga hias di pekarangan rumah masing-masing sebagai langkah awal menuju kegiatan usaha mikro berbasis tanaman hias. Kegiatan ini memberikan kontribusi nyata dalam membangun kesadaran masyarakat terhadap nilai estetika dan ekonomi dari tanaman hias serta mendorong inovasi pemanfaatan lahan pekarangan secara produktif. Dengan memanfaatkan teknologi digital dalam pelaksanaan sosialisasi, kegiatan ini membuktikan bahwa pengabdian kepada masyarakat tetap dapat dilakukan secara efektif dan efisien, meskipun dalam keterbatasan mobilitas. Keberlanjutan program ini diharapkan terjaga melalui pendampingan lanjutan dan pengembangan kelompok tani bunga hias secara swadaya masyarakat.

Abstract

Endophytic bacteria have the potential as environmentally friendly biocontrol agents in controlling bacterial leaf blight (BLB) in rice caused by Xanthomonas oryzae pv. oryzae (Xoo). This study aims to isolate, characterize morphology and biochemical tests, and test the antagonistic activity of endophytic bacteria from rice against Xoo. Isolation was carried out from healthy rice root tissue using a surface sterilization method. Morphological characterization included colony shape, color, edge, elevation, and Gram properties, while biochemical characterization included catalase, oxidase, motility, starch hydrolysis, and sugar fermentation tests. The antagonistic test used a dual culture assay method on NA (nutrient agar) media. The isolation results obtained six endophytic bacterial isolates (BETP 01–06) identified as the genus Pseudomonas and Bacillus with varying colony morphological characters. Antimicrobial activity test showed two potential isolates, BETP 03 (Pseudomonas) and BETP 05 (Bacillus), with an average inhibitory diameter of 16.3 mm and 16.5 mm against Xoo, respectively. Biochemical characterization showed that BETP 03 was bacillus, Gram-negative, citrate-negative, motile, gelatin hydrolysis positive, starch hydrolysis positive, and catalase positive; while BETP 05 was bacillus, Gram-positive, citrate-positive, motile, gelatin hydrolysis negative, starch hydrolysis positive, and catalase positive. These results indicate that both isolates have high potential as biological biocontrol agents in controlling bacterial leaf blight disease in rice.
