Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan Microbacter Alfaafa–11 (MA-11) dan pupuk organik terhadap karakteristik agronomi dan kualitas padi hasil persilangan Sigupai dengan IRBB27. Penelitian dilaksanakan di lahan SMK-PP Negeri Saree Jalan Banda Aceh-Medan KM. 69, Kecamatan Lembah Seulawah, Kabupaten Aceh Besar dan analisis sifat fisika dan kimia beras dilakukan di Laboratorium Ilmu dan Teknologi Benih dan Laboratorium Fisiologi Tumbuhan Fakultas Pertanian Universitas Syiah Kuala yang dilaksanakan pada bulan Februari 2023 sampai dengan Agustus 2023 menggunakan Rancangan Acak Kelompok (RAK) pola faktorial yang terdiri dari dua faktor. Parameter pengamatan yaitu karakteristik Agronomi yang terdiri dari tinggi tanaman, jumlah anakan, jumlah anakan produktif, umur mulai berbunga, panjang malai, jumlah malai, berat malai per rumpun, berat gabah per rumpun, persentase gabah berisi per rumpun, persentase gabah hampa per rumpun, berat 1000 butir, potensi hasil dan umur panen sedangkan uji kualitas beras terdiri dari sifat fisik yaitu rendemen beras giling, dimensi beras dan sifat kimia beras yaitu kadar air dan kadar protein. Hasil penelitian menunjukkan bahwa Microbacter Alfaafa–11 (MA-11) berpengaruh sangat nyata terhadap jumlah anakan pada umur 40 HST, rendemen beras, kadar protein dan berpengaruh nyata pada umur berbunga, dimensi beras padi hasil persilangan sigupai dengan IRBB27. Pupuk organik berpengaruh sangat nyata terhadap rendemen beras, dan berpengaruh nyata pada jumlah anakan umur 40 HST dan dimensi beras padi hasil persilangan sigupai dengan IRBB27. Tidak terdapat interaksi pada pemberian Microbacter Alfaafa–11 (MA-11) dan pupuk organik terhadap semua parameter pengamatan.

SUMMARY This research aims to determine the effect of using Microbacter Alfaafa-11 (MA-11) and organic fertilizer on the agronomic characteristics and quality of rice resulting from crossing Sigupai with IRBB27. The research was carried out on the land of the Saree State Vocational School-PP Jalan Banda Aceh-Medan KM. 69, Lembah Seulawah District, Aceh Besar Regency and analysis of the physical and chemical properties of rice was carried out at the Seed Science and Technology Laboratory and Plant Physiology Laboratory, Faculty of Agriculture, Syiah Kuala University which was carried out from February 2023 to August 2023 using a Randomized Block Design (RAK) pattern. factorial consisting of two factors. Observation parameters are agronomic characteristics consisting of plant height, number of tillers, number of productive tillers, age at which flowering begins, panicle length, number of panicles, panicle weight per hill, weight of grain per hill, percentage of filled grain per hill, percentage of empty grain per hill, weight of 1000 grains, yield potential and harvest age, while the rice quality test consists of physical characteristics, namely the yield of milled rice, dimensions of rice and chemical properties of rice, namely water content and protein content. The results of the research showed that Microbacter Alfaafa-11 (MA-11) had a very significant effect on the number of tillers at 40 DAP, rice yield, protein content and had a significant effect on flowering age and dimensions of rice resulting from crossing sigupai with IRBB27. Organic fertilizer had a very significant effect on the yield of rice, and had a significant effect on the number of tillers aged 40 DAP and the rice dimensions of the rice resulting from crossing sigupai with IRBB27. There was no interaction between the administration of Microbacter Alfaafa-11 (MA-11) and organic fertilizer on all observed parameters.
