Abstract
Abstrak. Gulma adalah tumbuhan yang hidup di sekitar tanaman yang dibudidayakan yang keberadaannya tak diharapkan serta sangat merugikan bagi tanaman yang di budidayakan dan mempengaruhi hasil pertanian yang diusahakan manusia. Teki adalah gulma yang mempunyai potensi untuk dimanfaatkan sebagai bioherbisida, dengan adanya senyawa kimia yang dikandung oleh teki yang dapat mengendalikan tumbuhan gulma lainnya. Penelitian ini diharapkan mampu mengetahui pengaruh ekstrak n-heksana teki pada berbagai konsentrasi bagi pertumbuhan bayam duri. Penelitian ini dilangsungkan di Laboratorium Ilmu Gulma Jurusan Agroteknologi Fakultas Pertanian, Laboratorium Analisis Kimia Fakultas Matematika dan Ilmu Pengetahuan Alam (FMIPA) serta Kebun Percobaan Fakultas Pertanian Universitas Syiah Kuala Banda Aceh, dari Desember 2021 sampai Maret 2022. Penelitian ini memakai Rancangan Acak Lengkap pola non faktorial dengan 6 perlakuan yaitu 2,4 D 0,686 kg b.a ha -1 (kontrol positif); aquades (kontrol negatif); ekstrak etil asetat teki 5%; 10%; 15%; 20%, dengan 3 kali ulangan, total terdapat 18 satuan percobaan. Hasil penelitian memperlihatkan bahwasanya aplikasi ekstrak n-heksana teki menghasilkan pengaruh yang sangat nyata bagi tinggi gulma, diameter batang, jumlah daun, serta persentase pengendalian gulma. Ekstrak n-heksana teki 20% mempunyai nilai persentase pengendalian gulma sebesar 53,33% dengan memberikan efek sedang terhadap pertumbuhan gulma bayam duri, namun berbeda dengan aplikasi herbisida sintesis (2-4D) yang memberikan nilai sebesar 100%.
