Vegetation analysis used combination method between strip and line compartment method. Result showed that no one of dominan species have association with Gonystylus bancanus in tree and pole level at IUPHHK-HA PT DRT.

Analisis Penggunaan Metode Barcode Printing dalam Pembuatan Papan Nama Koleksi di Kebun Raya Purwodadi

Plant record has been maintained by Purwodadi Botanical Garden since it was established in 1941. The plant label played an important role to locate the species maintained in the garden, and help to educate visitor through information hold by them. The plant labels in Purwodadi Botanic Garden are produced by plant registration department. To 2007, metal plate with handwriting were used for all types of collection. Although metal plate is proven to be durable and poses more artistic value, the label considered expensive and time consuming in the making. Later to this days, printed banner and sticker are employed for its economical and practical use. However this method has short-live compare to the former one. Considering more plants hold in collection, more efficient method is required. Recent innovation on barcode printing application appear to be more prospective and today being developed in Purwodadi Botanic Garden.The botanical garden is an ex-situ conservation area that has documented plant collections.  Each collection of plants has a label as an identity and as a differentiator from other conservation areas. Purwodadi Botanical Garden uses some methods to produce plant labels, namely handwritten method, banner printing method, and sticker printing method. Purwodadi Botanical Garden continues to innovate to find more effective and efficient methods. The barcode printing method is an innovation in plant label making which has some advantages, there are low prices, fast time, and load more information. This method is still under testing to see durability
