Abstract

Imperata cylindrica is a narrow-leaved weed that contains phenol compounds in the form of flavonoids and tannins that can inhibit the growth of other plants, so it has the potential as a bioherbicide. The purpose of this study was to determine the effect of methanol extract of rhizom I. cylindrica on the germination and growth of Mikania micrantha weed and to determine the concentration of methanol extract of rhizom I. cylindrica that well inhibits the germination and growth of  M. micrantha weed. This research started from March to December 2023 and was carried out at the Forest Products Chemistry Laboratory Faculty of Forestry, Laboratory and Cassa House Department of Biology, Faculty of Mathematics and Natural Sciences, Tanjungpura University, Pontianak. The method used in this research is Completely Randomized Design (CRD) with 5 concentration treatments of 0 g/ml (control); 0.1 g/ml; 0.2 g/ml; 0.3 g/ml and 0.4 g/ml, each treatment consists of 5 replicates. The results showed that methanol extract of rhizom I. cylindrica gave a significant effect on the germination and growth of M. micrantha weed. The methanol extract of rhizom I. cylindrica that best inhibits the germination of M. micrantha weed is a concentration of 0.2 g/ml and best inhibits the growth of M. micrantha weed is a concentration of 0.4 g/ml. Methanol extract of rhizom I. cylindrica has the potential as a bioherbicide to inhibit the growth of M. micrantha weed.

Abstract

Lemidi (Stenochlaena palustris) adalah gulma paku-pakuan yang mengandung senyawa alelokimia golongan alkaloid, tanin dan fenolik yang dapat menghambat pertumbuhan tanaman lain, sehingga berpotensi dimanfaatkan sebagai pengendali gulma. Tujuan penelitian ini adalah untuk mengetahui pengaruh ekstrak daun lemidi terhadap perkecambahan dan pertumbuhan rumput grintingan (Cynodon dactylon). Penelitian dilakukan pada bulan Oktober 2022 – Maret 2023 di Rumah Kasa Biologi dan Laboratorium Kimia Fakultas Matematika dan Ilmu pengetahuan Alam. Penelitian ini menggunakan Rancangan Acak Lengkap yang terdiri atas 5 perlakuan dengan 5 ulangan. Perlakuan terdiri dari ekstrak daun lemidi konsentrasi 0% sebagai kontrol, 7,5%, 10%, 12,5% dan 15%. Hasil penelitian menunjukkan ekstrak daun lemidi dapat menghambat perkecambahan dan pertumbuhan rumput grintingan. Konsentrasi 7,5% daun lemidi sudah menunjukkan penghambatan terhadap parameter pengamatan persentase perkecambahan, panjang kecambah, tinggi tanaman, jumlah daun, panjang akar, berat basah, dan berat kering rumput grintingan.
