Uji Kemampuan Ekstrak Daun Beberapa Jenis Sirih (Piper sp.) Untuk Mengendalikan Jamur Aspergillus sp. Pada Benih Kacang Tanah Secara In Vitro

Abstract

Vegetable fungicides are fungicides made from natural ingredients that are widely available in nature. One of the plants that can be used as a vegetable fungicide include several species of betel plants such as forest betel (Piper aduncum L.), red betel (Piper crocatum L.) and green betel (Piper betle L.). The use of several betel extracts can be used as an effective and efficient alternative control. This study aims to obtain the type of betel extract which has the potential as a vegetable fungicide that is able to control the fungus Aspergillus sp. The stages of this study consisted of the isolation of Aspergillus sp., Extraction and inhibition test of several betel extracts against the fungus Aspergillus sp., Seed treatment test with extracts of several types of betel. Based on research results giving green betel leaf extract, forest betel and red betel can inhibit the growth of the fungus Aspergillus sp. With the percentage of inhibition of 32.08%, 37.53% and 33.03% respectively. Giving betel leaf extract green, betel forest and red betel also can reduce the percentage of Aspergillus sp. amounted to 19.60%, 19.20% and 18.80% when compared to controls without administration of betel leaf extract. Application of several types of betel leaf extract and without betel leaf extract both produce a high percentage of normal sprouts (> 80%).
