Abstract

NURCAHAYA PURBA. Efficacy of Formulations Containing Ginger, Temulawak, Turmeric Extracts Against Ganoderma boninense Causes Basal Stem Rot in Oil Palm Seedlings (Supervised by SUWANDI). Oil palm (Elaeis guineensis Jacq.) is a very important commodity in plantations. Palm oil produces the most vegetable oil compared to other perennial crops. Disease has always been an obstacle in the growth of oil palm and can even have an impact on crop yields. One of the diseases that pose a threat to the palm oil industry in Southeast Asian countries, especially Indonesia, is basal stem rot caused by a soil pathogenic fungus that is very difficult to control, namely Ganoderma boninense. The disease also affects the seedling phase (vegetative). Therefore, the use of rhizome plant extract from ginger, temulawak, turmeric as a biopesticide that is antifungi. The purpose of this study was to determine the extent of effectiveness in inhibiting G.boninense from the formulation of ginger, temulawak, turmeric (JTmK) extract in vitro to determine the effect of the application of various concentrations on the suppression of the fungus G.boninense in planta early infection and advanced infection. This research method uses a Complete Randomized Design in vitro at a concentration of 0%, fungicide, 0.25%, 2.5%, JTmK extract mixed with tannins. Concentrations of 0%, 1.25%, 2.5%, 5% crude extract without tannins, each treatment 5 repeats. The initial infection in the greenhouse used a 2x3 factorial completely randomized design (RALF) with 8 treatments and 7 tests. The first factor is 0.25% (month 1-3, month 2-4 and month 1-2-3-4), the second factor is 2.5% (month 1-3, month 2-4, and month 1-2-3-4). Separate treatments are water control and Hexaconazole fungicide. Further infection trials used a randomized group design (RAK) of 0%, fungicides, 0.25%, 2.5%, each of the treatment concentrations of 5 repeats. The results showed that the treatment mixed with tannins concentration was 2.5% more inhibiting than other concentrations. As for crude extract, JTmK concentration is 5% more inhibiting than all crude concentrations. All concentrations of treatment did not differ markedly. Initial infection tests showed that concentrations of K1T1 (0.25% months 1-3) and K2T2 (2.5% months 2-4) tended to be higher in growth than controls. Further infection tests showed that the concentration of 2.5% tended to be higher than the control although for all treatments there was no noticeable difference. This study shows that all concentrations applied every month do not show any real inhibition of BPB. The results showed that the treatment given could not treat Ganoderma infection in oil palm seedlings. Keywords: Oil palm seeds, Ganoderma boninense, Ginger extract, Temulawak, turmeric
