Abstract
Abstract. Red ginger rhizome (Alpinia purpurata K Schum) is a plant of the zingeberales tribe used as a biopesticide for the control of plant disturbance organisms (OPT) because they contain essential oils that effective as anti-bacterial and anti- fungal. This study aims to Knowing the potential of rhizome extract, analyze the effective with Red ginger rhizome extracts and Counting disease intensity index (IIP) to growth Hemileia vastartix after a given treatment. The main material used in this study is simplicia red ginger rhizome extracted with 100 ml of distilled water using a solvent, in order to obtain a liquid extract. Liquid extract of the rhizome third in fungi tested as antifungal Hemileia vastartix B. et Br by using the leaf disc method and the concentrations used are red ginger rhizome (6 grams, 7 grams, and 8 grams) with positive control 0.3 % Comparative Nordox and negative control treatment provision Hemileia vastartix. The results showed that red ginger rhizome extract with a concentration of 8 grams have the highest degree of effective in inhibiting the growth of vastartix Hemileia equivalent to 0.3% Nordox comparison indicated from the calculation of IIP (Index Intensity Disease) is equal to 0.00% .
Key Words: red ginger rhizome, Hemileia vastartix B. et Br, the calculation of IIP (Index Intensity Diseases) analisis.
