چکیده

Abstrak. Gulma yaitu tumbuhan yang hidup di sekitar tanaman budidaya keberadaannya tidak diinginkan, seringkali merugikan karena dapat menghambat pertumbuhan sehingga menyebab kan penurunan kuantitas dan kualitas produksi pertanian. Tujuan penelitian ini adalah untuk mengetahui aktivitas ekstrak etil asetat babadotan (Subfraksi B) terhadap gulma bayam duri. Penelitian dilakukan Laboratorium Ilmu Jurusan Agroteknologi Fakultas Pertanian, Herbarium Biologi Matematika Pengetahuan USK, Kimia Organik Alam (FMIPA) Kebun Percobaan Pertanian Banda Aceh mulai Januari - Juli 2022. Bahan dasar digunakan dalam (Ageratum conyzoides L.) dengan pelarut indikator duri (Amaranthus spinosus L.).
