Belitung is known as the biggest tin mining in Indonesia. Besides that, Belitung also has a lot of biological resources, that is Odonata (dragonfly). The research was conducted in June 2018 by exploration in Belitung, particularly in Punai beach and Kerangas forest (ex-tin mining) area. There is found 17 type of dragonfly such as Ichtinogomphus decoratus., Macrogomphus sp., Orthetrum sabina., Nannophya pygmaea., Neurothemis fluctuans., Rhodothemis rufa., Rhyothemis phyllis., Urothnemis signata., Pseudagrion coomansi., Ceriagrion cerinorubellum., Acisoma panorpoides., Brachydiplax chalybea., Diplacodes nebulosa., Orthetrum pruinosum., Agriocnemis femina., Agriocnemis pygmaea., and Ischnura senegalensis. All species were conducted to find out the diversity using Shannon-Wiener index and resulting 2,77 index.

We grew cucumber in pots in greenhouse for 9-successive cropping cycles and analyzed the rhizosphere Pseudomonas spp. community structure and abundance by PCR-denaturing gradient gel electrophoresis and quantitative PCR. Results showed that continuous monocropping changed the cucumber rhizosphere Pseudomonas spp. community. The number of DGGE bands, Shannon-Wiener index and Evenness index decreased during the 3rd cropping and thereafter, increased up to the 7th cropping, however, however, afterwards they decreased again. The abundance of Pseudomonas spp. increased up to the 5th successive cropping and then decreased gradually. These findings indicated that the structure and abundance of Pseudomonas spp. community changed with long-term cucumber monocropping, which might be linked to soil sickness caused by its continuous monocropping.
