Abstract

Tanaman paku kijang (Blechnopsis orientalis L) dikenal memiliki berbagai khasiat pengobatan alternatif, antara lain untuk mengatasi bisul, cacingan, diare, gangguan saluran kemih, kebingungan akut (igauan), sebagai kontrasepsi alami, mengatasi kulit gatal dan luka, serta membantu meringankan leukemia, maag, sakit kepala, sakit telinga, sakit perut, dan tifus. Penelitian ini bertujuan untuk mengetahui efek ekstrak batang paku kijang (Blechnopsis orientalis L) dalam menghambat pertumbuhan bakteri Escherichia coli. Ekstrak batang paku kijang diperoleh dari hasil maserasi meggunakan pelarut etanol 70% dan menghasilkan ekstrak kental dengan rendemen 12,27%. Pengujian aktivitas antibakteri dilakukan dengan menggunakan metode difusi cakram. Penelitian ini menggunakan tiga perlakuan, yaitu sampel 2%, kontrol positif (kloromfenikol) dan kontrol negatif (aquades). Hasil pengujian aktivitas antibakteri menunjukkan bahwa ekstrak batang paku kijang pada konsentrasi 2% memiliki aktivitas antibakteri terhadap bakteri Escherichia coli dengan daya hambat yaitu 8,816 mm yang digolongkan sebagai antibakteri dengan daya hambat sedang.

Abstract (English)

The deer fern plant (Blechnopsis orientalis L) is known to have various alternative medicine properties, including to treat ulcers, worms, diarrhea, urinary tract disorders, acute confusion (delirium), as a natural contraceptive, overcome itchy skin and wounds, and help relieve leukemia, ulcers, headaches, earaches, stomachaches, and typhus. This study aims to determine the effect of deer spike stem extract (Blechnopsis orientalis L) in inhibiting the growth of Escherichia coli bacteria. The extract was obtained from maceration using 70% ethanol solvent and produced a thick extract with a yield of 12,27%. Antibacterial activity testing was carried out using the disc diffusion method. This study used three treatments, namely 2% sample, positive control (chloromfenikol) and negative control (distilled water). The results of antibacterial activity testing showed that the extract of deer spike stems at a concentration of 2% has antibacterial activity against Escherichia coli bacteria with an inhibition of 8.816 mm which is classified as an antibacterial with moderate inhibition.
