Abstrak. Penelitian ini bertujuan untuk mengetahui perubahan komposisi gulma akibat campuran herbisida oksifluorfen, pendimethalin, dan sulfentrazone pada tanaman kedelai. Penelitian ini dilaksanakan di Desa Rumpeet, Aceh Besar pada ketinggian 6 meter diatas permukaan laut (dpl) dan Laboratorium Pengelolaan Gulma, Fakultas Pertanian, Universitas Syiah Kuala, Banda Aceh dari bulan September-Desember 2020. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) pola non faktorial dengan kombinasi 10 perlakuan. Peubah yang diamati adalah persentase pengendalian gulma, persentase penutupan gulma, spesies gulma, populasi gulma, dan bobot kering gulma. Hasil penelitian menunjukkan bahwa campuran herbisida berpengaruh terhadap persentase pengendalian gulma, persentase penutupan gulma, jumlah spesies gulma, jumlah populasi gulma dan bobot kering gulma. Herbisida sulfentrazone dosis 1 kg b.a ha-1 mampu meningkatkan persentase pengendalian gulma, menurunkan persentase penutupan gulma, spesies gulma, populasi gulma dan bobot kering gulma.

Abstract. This study aims to determine changes in weed composition due to tank mixture of herbicide oxyfluorphen, pendimethalin, and sulfentrazone in soybean plants. This study was conducted in Rumpeet Village, Aceh Besar at an altitude of 6 meters above sea level (asl) and the Weed Management Laboratory, Faculty of Agriculture, Syiah Kuala University, Banda Aceh during September-December 2020. The study using a non-factorial randomized block design with a combination of 10 treatments. The variables observed were percentage of controlled weed, percentage of weed coverage, weed species, weed population, dry weight of weed, and community coefficient. The results showed that tank mixture of herbicide affected percentage of controlled weed, the percentage of weed coverage, weed species, weed populations and the dry weight of weed. Sulfentrazone herbicide dosage of 1 kg a.i. ha-1 was able to increase the percentage of controlled weed, reduce the percentage of weed coverage, weed species, weed population and weed dry weight
