Abstract

Isolation of entomopathogenic fungi and their extracellular enzyme activity from rhizosphere soil were carried out. Soil samples were collected from rhizosphere under Arecaceae plant collection and a shrub in Bogor Botanic Garden, West Java; and another samples were gathered from forest floor on peat land in Sebangau National Park, Central Kalimantan. Insect bait method was used to catch fungi from soil samples by using Coptotermes sp. termites and Xystrocera festiva larva in the laboratory. A total of 38 fungal isolates belonging to 18 species and 12 genera were successfully isolated and identified. Isolated fungi were dominated by Deuteromycotina; and Fusarium is the most common (5 species). Peat and Pinanga coronata rhizospheres; and termites bait gave the highest fungal diversity of 9 species respectively. All fungal isolates did not indicate chitinase activity, but 60.53 %, 10.53 % and 13.16 % had both of lipase and protease; lipase and protease activities, respectively. Only 15.79 % fungal isolates were negatively in lipase or protease activities.

Abstract

Due to the climate change and global warming, the biodiversity database has gained the attention of the government. In line with the Indonesian Biodiversity Strategy and Action Plan (IBSAP), we have collected plants with insecticidal activity based on the local wisdom. This program aimed to protect Indonesian biodiversity from deforestation along with the loss of the number of species. This research?s goal was to evaluate termiticidal and antifungal properties from some plant extracts collected from the Turgo forest area, Mt. Merapi National park, Java. Three potential plants were evaluated. Based on specimen identification, the three plant samples were Kina (Cinchona sp.), Kamadoh (Dendrocnide stimulans (L.f.) Chew), and Keremi (Homalanthus populneus (Geiseler) Pax). The phytochemical test showed that Kina contained alkoloid, falvonoid, saponin, and tannin, whereas Kamadoh and Keremi contained saponin and tanin, respectively. Overall, all plant extracts have the termiticidal activities and able to inhibit wood- decay fungi with the inhibition percentage around 60% - 100%. Leaf extracts of Kina (Cinchona sp) and Keremi (Homalanthus populneus (Geiseler) showed the highest activity as wood-decay fungi inhibitor. The disclosure of the potential of bioinsecticides from some plants originating from Mount Merapi is very important before being lost due to deforestation and the Mount Merapi disaster. Thus, the potential bioinsecticide in these plants can increase its economic value as a substitute for synthetic insecticides that are friendly to the environment.
