Abstract

Padang Sugihan Wildlife Reserve covering 86,932 hectares is the natural habitat of elephants in South Sumatra, both wild and managed elephants at Elephant Training Center, Sub Padang Sugihan. This area was used to be production forest. To support life of wild elephants, the vegetation quantity and diversity of vegetation types of feed must be known. This study aimed to analyze the vegetation feed elephants in Padang Sugihan Wildlife Reserve. The method used sampling plots with a size of 1m x 1m and 5m x 5m in five study sites. Data were analyzed using analysis of vegetation to get the importance value index. Species diversity was calculated using the Shannon Wienner Index formula. It was also calculated the value of uniformity of plant based on Simpson formula. The results of importance value index showed that location I was dominated by Echinochloa colonum (L.) Link (76.55%), location II Panicum astagninum R (132.48%), location III  Panicum repens L (107.14%), location IV Axonopus caompressus ( 79.48%), location of V Panicum repens L and Cynodon dactylon (L.) Pers. (21.28%), location VI Melaleuca cajuputi (80.77%), and location VII Melaleuca cajuputi (84.08%). The value of the highest species diversity in the location of V at 2.53. The lowest value was in location II at 0.66. The highest uniformity index was 0.92. While the lowest value was 0.37 in the location II. Based on the above results it is necessary to enrich the vegetation species of elephant grass and natural food, especially at locations II and III.   Keyword: Padang Sugihan Wildlife Reserve, vegetation analysis, Elephas maximus sumateranus Temminck

Abstract

The aim of this research to analyze the difference of apple farm quality the influence of  intensification of agriculture system with environmentally-friendly of agriculture system. A descriptive field research was conducted in June until August 2012. The soil samples were taken in each location by using disturb sample method. The Arthropods sample were taken every five days for five time by using pitfall trap method with five transek in each location.The research applied a  qualitative and quantitative-descriptive. The farm quality were comparison soil quality analyze and  compositions of ground Arthropods. The composition of ground Arthropods were analyzed using Important Value Index and the diversities were analyzed by using Shannon Wiener Index. The result showed that farm quality with environmentally-friendly of agriculture system was better than intensification of agriculture system. The ground Arthropods collected at 150 pitfall trap in environmentally-friendly of agriculture system were 15.079 individual while those in intensification of agriculture system were 9.461 individual. Based on Important Value Index (40,83-64,31), Collembolla ordo Entomobryidae family dominated in each location. Based on Shannon Wiener Index that diversity of ground Arthropods in intensification of agriculture system (H’= 1,58-2,04) was greater than environmentally-friendly of agriculture system (H’= 1,56- 1,99), but both of them at medium criteria.   Keywords : farm quality, agriculture system, Arthropods composition
