Diversity and Distribution of Myrmecophytes in Bengkulu Province

Abstract: Myrmecophyte is a common medicinal plant used by local people in Indonesia for treating various diseases especially in Papua. Bengkulu province is one of the Myrmecophyte habitats, but there has no report on its identity and distribution. The objectives of this research were to identify the diversity and analyze the Myrmecophytes distribution as well as factor affecting its presence. This study used purposive sampling method by exploring the area where Myrmecophytes commonly found. The Myrmecophyte distribution based on host tree was analyzed using Morishita index and the autecological analysis of abiotic factors was performed using Principal Component Analysis (PCA) generated from Minitab 16. The results of this research showed that there were two species of Myrmecophytes in Bengkulu province, namely Hydnophytum formicarum and Myrmecodia tuberosa , as well as two variants of M. tuberosa i.e. M. tuberosa ‘armata’ and M. tuberosa ‘siberutensis’. The distribution of Myrmecophytes based on host tree was mostly randomly scattered in Central Bengkulu regency, Seluma, North Bengkulu, South Bengkulu, and Kaur. Their distributions were affected by light intensity and temperature. The data of this research can be used as basic information for carried out conservation efforts in Bengkulu province. The abundance of Myrmecophytes is also used as a source of additional income for local people in Bengkulu province.

Species Richness and Habitat Suitability of Myrmecophytes in Bengkulu : Host Tree, Coexist Epiphytes and Animals

Abstract: Myrmecophytes or locally known as simbagh utak are common medicinal plants used by locals in Bengkulu, especially in South Bengkulu, for treating various diseases. Despite their potential as medicines, there is no report on biotic factors can be used to indicate of Myrmecophytes species’ richness and habitat suitability. The objectives of this research were to analyze the Myrmecophytes’ species richness and habitat suitability. This study used the purposive sampling method by exploring the area where Myrmecophytes were commonly found. The biotic factors of Myrmecophytes were analyzed by identifying the tree host, the other epiphyte plant grew around them, and animal occupants on the tuber of the Myrmecophytes. The Myrmecophytes distribution was analyzed by using ArcGIS10.1. The results showed that there were two species of Myrmecophytes, namely Hydnophytum formicarum and Myrmecodia tuberosa in the study area. The Myrmecophytes attached and hung in 9 species of host trees . The characteristics of host trees are high trees with large diameter, mostly rough-barked; some were cracked and mossy. The highest frequency of host trees included Hevea brasiliensis and Durio zibethinus . Myrmecophytes coexisted with 12 species of epiphytes. Epiphyte plants like Dendrobium sp. and Drymoglossum piloselloides can be used to indicate the presence of Myrmecophytes. Ants made up the most predominantly animal found living inside the tubers of Myrmecophytes, with some cockroaches and termites found at the tuber of Hydnophytum. Information on species' richness and habitat suitability of Myrmecophytes can serve as supporting data for conservation efforts in Bengkulu to prevent the extinction of this species.

Autekologi purnajiwa (euchresta horsfieldii (lesch.) benn. (fabaceae) di sebagian kawasan hutan bukit tapak cagar alam batukahu bali

Abstract: Purnajiwa, which lives in highland jungles in Bali, is a famous medicinal plant in Bali and its presence in the wild is now under threat due to over exploitation and the destruction of its habitat. Batukahu nature reserves are one of its remaining habitats. This preliminary study aimed to describe purnajiwa’s habitat in Batukahu nature reserves. Purnajiwa was found in shaded areas with light intensity range from 55-65%. It grows under the shading of Laportea sp., Ficus sp., Syzygium zollingerianum, and Sauraria sp. Purnajiwa grows on soil with 6,7-6,8 range of pH with litter thickness of 3-7 cm. Purnajiwa also associated with the surrounding understorey vegetation such as Diplazium proliferum (IVI = 54,6) and Oplismenus compositus L. (IVI = 40). Result from this study gave usefull information for the purpose of its acclimatization and propagation in ex-situ conservation for its sustainable resources.

Studi karakteristik pohon inang anggrek di kawasan cagar alam pangi binangga desa sakina jaya kabupaten parigi moutong

Abstract: Pangi Binangga Nature Reserve is one of the conservation sites geographically located at Parigi Moutong District Central Sulawesi Province. The reserve is known to be the host of many protected species of flora and fauna including orchids. However, species richness of orchids decreased over time due to habitat degradation as well collection for commercial purposes as ornamental type of vegetation to improve community’s income. This research was to endeavor characteristics of the host trees for the orchids living in the reserve. The research was conducted from November 2014 to January 2015 using line transect methods. Transects were placed on the line purposively. Observation transects form were Quadratic with size of 20 m x 20 m. The research (applying 5 observation plots) revealed that there were 12 tree species that function as host. In general, most orchids like to have host with thick bark, coarse and scratches as well as wide canopy to cover orchids reproduction. Interestingly, it was found that each host has different orchid species (12 species). Keywords: host tree characteristics, orchids, Pangi Binangga Nature Reserve

PENGARUH EKSTRAK UMBI “SIMBAGH UTAK” (Hydnophytum sp) TERHADAP KADAR ASAM URAT Mus musculus JANTAN DAN KARAKTERISASI HASIL ISOLASI MENGGUNAKAN FTIR

Abstract: Penelitian ini bertujuan untuk mengetahui pengaruh ekstrak umbi “simbagh utak” (Hydnophytum sp) terhadap kadar asam urat darah M. musculus jantan yang diberi pakan tinggi purin dan mengetahui gugus fungsional dalam umbi Hydnophytum sp menggunakan FTIR. Sebanyak 25 ekor M. musculus jantan dibagi menjadi 5 kelompok.Kelompok 1 (K1) sebagai kontrol normal diberi pakan standar yaitu pelet. Kelompok 2 (K2) sebagai kontrol negatif diberi pakan tinggi purin. Kelompok 3-5 (K3,K4,K5) masing-masing diberi perlakuan pakan tinggi purin dan ekstrak Hydnophytum sp dengan dosis berturut-turut 5,3mg/30 gBB, 10,2mg/30gBB dan 21,2mg/30gBB secara peroral. Pengukuran asam urat dilakukan dengan metode digital menggunakan easy touch/GCU.Proses ekstraksi dilakukan mengggunakan maserasi dan ekstraksi cair-cair. Pemilihan eluen dan pemisahan komponen yang diisolasi dilakukan menggunakan kromatografi lapis tipis dan kromatografi kolom.Hasil isolasi dikarakterisasi menggunakan spektroskopi FTIR. Hasil penelitian menunjukkan bahwa ekstrak umbi “simbagh utak” dosis 5,3mg/30gBB, 10,2mg/30gBB dan 21,2mg/30gBB dapat menurunkan kadar asam urat M. musculus jantan yang diberi pakan tinggi purin berturut-turut sebesar 34,1%, 48,0% dan 53,4%. Karakterisasi hasil isolasi menggunakan FTIR menunjukkan adanya gugus –OH, C=O, C-H alifatik, C=C aromatik, -CH2, C-H aromatik, dan C-O yang diduga merupakan gugus fungsi dari senyawa flavonoid.
