Abstract

Taxonomic study on Pandanus (Pandanaceae) in swamp area, Singkil had been conducted from November 2012 until June 2013. Based on morphological characters,  5 species of Pandanus have been identified in the area  as  Pandanus atrocarpus, Pandanus labyrinthicus, Pandanus militaris, Pandanus odoratissimus and Pandanus tectorius. The morphology and life cycle of species were categorized into two types, and they are medium arborescent pandan  (Pandanus labyrinthicus and Pandanus militaris) and large arborescent pandan (Pandanus atrocarpus, Pandanus odoratissimus and Pandanus tectorius).  Anatomical characters of Pandanus such as stomata (type, size, papilla) and epidermal cells supported the morphological features.

Abstract

GRADSTEIN, R. et al. 2010. Bryophytes of Mount Patuha, West Java, Indonesia. Reinwardtia 13(2): 107-123. - This paper presents the results of a two-day survey of the bryophyte flora of Mt. Patuha and its surroundings near Bandung, West Java, carried out in the framework of the 5th regional training course on bryophyte and lichen diversity and conservation organized by SEAMEO BIOTROP, Bogor, in July 2009. A total of 159 bryophyte species were identified, including 98 mosses, 60 liverworts, and 1 hornwort, representing almost 1/6 of the total bryophyte flora of Java. Three moss species, Bryohumbertia subcomosa (Dix.) J.-P. Frahm, Fissidens gymnogynus Besch. and F. polypodioides Hedw., and one liverwort, Lejeunea pectinella Mizut., are new additions to the Javanese flora. The bryophyte diversity of Mt. Patuha is well representative of the Malesian flora and is rich in uncommon species. However, the relatively poor representation of shade epiphytes and commonness of sun epiphytes and generalists reflect disturbance of the forest by anthropogenic activities. Careful attention should be given to conservation of the remaining natural forest in order to prevent further losses of the rich bryophyte diversity of the area.

Abstract

The jamblang distribution has been studied in the southern part of  Aceh Besara, which is in the South of Jhanto district, Northern Krueng Raya, Southern Masjid Raya and Ujung Pancu district. The aims ofthis study was to determine the distribution area of jamblang based on rainfall, soil type, and lands cover . The data were collectedby observation. Distribution data are presented in the  form of map using ArcView 3.3 Software. The results of the analysis showed that the common jamblang was distributedin the rainfall region of 1500-2500 mm/year in dryland farming and the chromic luvisols, humic acricols, dystric fluvisols, dan rendzinas.

Abstract

The diversity of tree, pole and potential of carbon stored in 30 years secondary forest and coffee field at Telagah District of Langkat was investigated from February to June 2012. The  study site was determined by purposive sampling method with total area 40 x 200 meters. The study site is divided into 20 plots and sub plots. Result found that 15 families and 23 species for tree phase and 16 families and 26 species of pole phase. The area were dominated by Macaranga tanaria with important value 57.11% for tree, and followed by Ficus aurantiacea with important value 54. 472% for pole. The diversity index of tree is 2.650 and 2.715 for pole. Equitability index of tree is 0.520 and 0.586 for pole. The potential of carbon stored in tree is 146.519 ton/ha, 3.933 ton/ha for pole, and 0.0489 ton/ha for coffee plantation.   Keywords: Carbon, Coffee Plantation, Diversity, Important value index, pole, purposive sampling

Abstract

The composition and structure of Grasses in Haranggaol Village Haranggaol Horison Subdistrict Simalungun Regency North Sumatra has been studied from April to July 2012. The objective of the study was to determine the composition and structure of grasses at different altitudes. Sampling area was defined by purposive sampling method  and divided into three locations based on altitude with 20 plots of 1 x 1 m size for each area. From the study it was found 24 species of grasses that belong to two families. The first location was dominated by Microstegium ciliatum (81.095%), the second was dominated by Deyeuxia brachyathera (68.504%) and the third was dominated by Leersia hexandra (79.158%). The diversity index  (H')  of grasses are 1.557, 1.790 and 1.414 in the location I, II and III, respectively and equitability index (E) of grasses are 0.607, 0.661, 0.726 in the location I, II and III, respectively. The similarity index ranges from 30 to 50%, with the highest similarity index is 50% that was found between location I and II.   Keyword: composition, grass, Haranggaol, structure
