Abstract

Penelitian ini bertujuan untuk mengetahui kemampuan rizobakteri yang diberikan melalui perlakuan benih mempengaruhi induksi ketahanan bibit kakao terhadap penyakit busuk buah (Phytophthora palmivora Butl.). Penelitian ini dilaksanakan di Laboratorium Ilmu dan Teknologi Benih, Jurusan Agroteknologi, Fakultas Pertanian Universitas Syiah Kuala, Darussalam Banda Aceh sejak September 2020 sampai Februari 2021. Rancangan yang digunakan ialah Rancangan Acak Lengkap (RAL) non faktorial dengan 7 perlakuan yang diulang sebanyak 3 kali sehingga diperoleh 21 unit perlakuan. Peubah yang diamati ialah persentase penghambatan pertumbuhan koloni patogen, laju penghambatan pertumbuhan koloni patogen, pengukuran aktivitas peroksidase, potensi tumbuh maksimum, daya berkecambah, keserempakan tumbuh, kecepatan tumbuh relatif, waktu yang dibutuhkan untuk mencapai 50% perkecambahan total relatif, tinggi tanaman, diameter batang dan jumlah daun. Hasil penelitian ini menunjukkan bahwa rizobakteri berpengaruh sangat nyata terhadap persentase penghambatan pertumbuhan koloni patogen, laju penghambatan pertumbuhan koloni patogen, pengukuran aktivitas peroksidase, daya berkecambah, kecepatan tumbuh relatif , tinggi tanaman bibit kakao umur 28 HST, tinggi tanaman bibit kakao umur 35 HST, diameter batang bibit kakao umur 28 HST, diameter batang bibit kakao umur 35 HST dan jumlah daun bibit kakao umur 28. HST. Resistance Induction of Cocoa Seeds Against Fruit Rot Disease (Phytophthora palmivora Butl.) Using Rhizobacteria-Threated Seed This study aimed to determine the ability of rhizobacteria given through seed treatment to influence the induction of resistance of cocoa seedlings to fruit rot disease (Phytophthora palmivora Butl. ). This research was conducted at the Seed Science and Technology Laboratory, Department of Agrotechnology, Faculty of Agriculture, Syiah Kuala University, Darussalam Banda Aceh from September 2020 to February 2021. The design used was a non-factorial Completely Randomized Design (CRD) with 7 treatments and 3 times replications for experiments, so there were 21 experimental units. The variables observed were the percentage of inhibition of pathogenic colony growth, rate of inhibition of pathogenic colony growth, measurement of peroxidase activity, maximum growth potential, germination, growth simultaneity, relative growth rate, the required time to reach 50% of relative germination, plant height, stem diameter and number of leaves. The results of this study showed that rhizobacteria had a very significant effect on the percentage of inhibition of pathogenic colony growth, rate of inhibition of pathogenic colony growth, measurement of peroxidase activity, germination, relative growth rate, height of cacao seedlings 28 DAP, height of cacao seedlings 35 DAP, stem diameter of cacao seedlings 28 DAP, stem diameter of cacao seedlings 35 DAP and numer of leaves of cacao seedlings 28 DAP.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh perlakuan benih menggunakan rizobakteri pemacu pertumbuhan tanaman dan jenis rizobakteri yang tepat terhadap peningkatan pertumbuhan dan produksi tanaman okra. Penelitian ini dilaksanakan di Kebun Percobaan 1 dan Laboratorium Ilmu dan Teknologi Benih Fakultas Pertanian Universitas Syiah Kuala yang berlangsung pada bulan Oktober sampai Desember 2020. Percobaan disusun berdasarkan rancangan acak kelompok (RAK) non faktorial dengan 16 perlakuan yang terdiri atas 15 perlakuan isolat rizobakteri dan perlakuan kontrol. Setiap perlakuan diulang sebanyak 3 kali. Hasil penelitian menunjukkan bahwa perlakuan terbaik terdapat pada jenis rizobakteri Bacillus badius yang mampu meningkatkan parameter tinggi tanaman okra 15, 30, 45 dan 60 HST dan jenis rizobakteri Bacillus larvae yang mampu meningkatkan diameter batang 60 HST, jumlah daun 45 dan 60 HST serta berat buah pertanaman. The Effect of Seed Treatment Using Plant Growth Promoting Rhizobacteria on Growth and Production of Okra (Abelmoschus esculentus L. Moench) This study aims to determine the effect of seed treatment using plant growth promoting rhizobacteria and the right types of rhizobacteria on increasing growth and production of okra. This research was conducted at Experimental Garden 1 and Seed Science and Technology Laboratory, Faculty of Agriculture, Syiah Kuala University from October up to December 2020. Randomized Block Design (RBD) non factorial that consisted 16 treatments was used in the research. The treatments were control and 15 rhizobacteria isolates, every treatment was replicated 3 times. The results showed that the best seed treatment using rhizobacterial isolates Bacillus badius was able to increase the height parameters of okra plants 15, 30, 45 and 60 DAP, and rhizobacteria of Bacillus larvae were able to increase stem diameter 60 DAP, number of leaves 45 and 60 DAP and weight of fruit in a plant.
