| Abstrak (Bhs. Indonesia) | Penelitian ini bertujuan untuk menguji keefektifan aplikasi P. fluorescens P60 yang diperkaya kitosan terhadap penyakit hawar pelepah daun pada tanaman jagung dan mengetahui pengaruh aplikasi P. fluorescens P60 yang diperkaya kitosan terhadap pertumbuhan tanaman jagung. Penelitian dilakukan di Laboratorium Perlindungan Tanaman dan lahan Percobaan Fakultas Pertanian Universitas Jenderal Soedirman, pada bulan Desember 2019 sampai Agustus 2020. Rancangan percobaan yang digunakan dalam penelitian yaitu Rancangan Acak Lengkap dan Rancangan Acak Kelompok yang terdiri atas empat perlakuan. Perlakuan yang dicoba yaitu kontrol, P. fluorescens P60 yang diperkaya kitosan 1, 2, dan 3%. Variabel yang diamati adalah zona hambatan, masa inkubasi, intensitas penyakit, laju infeksi, AUDPC, tinggi tanaman, bobot tanaman segar, dan bobot akar segar. Hasil penelitian menunjukkan P. fluorescens P60 yang diperkaya kitosan 3% efektif dalam menghambat pertumbuhan R. solani dengan tingkat penghambatan 63,3%, menghasilkan enzim kitinase dan protease, serta dapat mengendalikan penyakit hawar pelepah jagung dengan menunda masa inkubasi 79,05%, menurunkan intensitas penyakit 50%, menurunkan laju infeksi 33,3%, dan menurunkan AUDPC 83,32%. P. fluorescens P60 yang diperkaya kitosan 3% efektif dalam meningkatkan pertumbuhan tanaman dengan meningkatkan bobot tanaman segar 51,28% dan bobot akar segar 75,73% dibanding kontrol. |

| Abtrak (Bhs. Inggris) | This research aims to test the effectiveness of kitosan-enriched P. fluorescens P60 application to leaf-melting hawar disease in corn crops and to determine the effect of chitin-enriched P. fluorescens P60 applications on corn crop growth. The research was conducted at the Laboratory of Crop Protection and Experimental farm, Faculty of Agriculture of General Sudirman University, from December 2019 to August 2020. The experimental design used in the study was a Complete Randomized Design and a Randomized Group Design consisting of four treatments. The treatment tried is control, P. fluorescens P60 enriched with chiosan 1, 2, and 3%. The variables observed were inhibition zone, incubation period, disease intensity, infection rate, AUDPC, plant height, fresh plant weight, and fresh root weight. The results showed P. fluorescens P60 enriched with chitosan 3% was effective in inhibiting the growth of R. solani with an inhibition rate of 63.3%, produced chitinase and protease enzymes, delayed the incubation period by 79.05%, and reduced the disease intensity by 50%, the infection rate by 33.3%, and AUDPC by 83.32%. P. fluorescens P60 enriched with chitosan 3% was effective in improving plant growth by increasing fresh plant weight by 51.28% and fresh root weight 75.73% compared to control. |
