Abstract

composition of plant species and the amount of carbon stocks stored in Nature Reserve Forest Lembah Harau at tree level and the level of the pole. The sampling intensity is 5 % of the total area of 270.5 ha. So that the total area of observation is 13.525 ha with a plot measuring 20 m x 100 m were 68 plots. In each plot were made sub-sub plot measuring 20 m x 20 m for tree and 10 m x 10 m for pole. Vegetation analysis use a combination of track method and swath line method, while the biomass estimation use non destructive sampling method. The results showed that 80 kinds of plants with a number of individuals as much as 246 individuals/ha. The highest important value indeks of tree species is Rhodelia teysmani with the value 53.33 %, while in the pole species is Nephelium mutabile with the value 46.30 %. The amount of carbon stocks stored in trees and poles are 62.57 ton/ha.Keywords : vegetation , carbon stock , nature reserve lembah harau

Abstract

This research aimed to estimate the carbon stocks in Casuarina equisetifolia L according to the habitat and to compare the carbon stocks of Casuarina equisetifolia L on two different  locations. The method used to calculate carbon stocks is non-destructive method. The result showed that the amount of carbon stocks in Sri Mersing Beach is 18,524 ton/ha while in  the Gudang SCM PT.Pertamina Beach is  11,45 ton/ha. The average of carbon stocks in Sri Mersing Beach is 154,36 kg/tree while in the Gudang SCM PT. Pertamina Beach is 69,57 kg/tree . The differences between the amount of carbon stocks in this two research areas are caused by the density of trees and silviculture factor.Key words : Carbon stock, Casuarina equisetifolia L, Sri Mersing Beach, Gudang SCM PT.                     Pertamina Beach.

Abstract

Daun Sang is an endemic species that can be found in Gunung Leuser National Park and Bukit Tiga Puluh National Park. This palm is thought to have associations with other palm. Where around Daun Sang grow there are palm types Lipai (Licuala spinosa), but not always around Lipai grow Daun Sang are. Daun Sang need shade to grow because these palm is sensitive to the sunlight. This study  aimed to analyze the association  of daun sang by some kind of palm that grows around in order to conservation and optimize the cultivation of the daun sang. The method used is a descriptive method with observation of the Daun Sang number and some kind of of palms around it done intentionally (purposive sampling). The method is performed by making 2 plot observations, each size is 100m × 100m,  then divided by making the sample plots of 20m × 20m. Observed data were processed using 2 x 2 contingency table, and then calculated by the chi-square test formulations and Jaccard index to calculate the extent of the association. three species of palm found in the study site there are pinanga speciosa, tetradactylus and Plectomiopsis Calamus sp. The results showed that daun sang are not associated with Pinanga speciosa. Association occurs between daun sang with the Calamus tetradactylus and daun sang with Plectomiopsis sp. The highest level of association occurs in Daun Sang and Calamus tetradactylus with maximum association index value of 1. The level of association between Daun Sang with Plectomiopsis sp. approaching the maximum value of the association index in 0.84.Key word : Daun Sang (Johannesteijsmania altifrons), Association Analysis, Ressort Sei Betung

Abstract

Mangrove forest area is currently very vulnerable to environmental changes such as ecological pressures that come from nature and people. Preservation of mangrove area is very necessary, however the need of people’s livelihood around the mangrove areas can not be ignored as well. Accordingly, a business pattern which combines mangrove area and community pond system is developed, It is well known as silvofishery. This study aims to assess the financial analysis of silvofishery system and non silvofishery system and analyze the contribution of the pond business to the total income of household. This research was conducted in October - December 2014 and was held in Paluh Manan Village, Hamparan Perak Sub-District, Deli Serdang District, North Sumatra Province. This research used census method which the informants were interviewed directly. Comparative result of the financial analysis pond system shows the NPV and BCR of silvofishery is higher than the NPV and BCR of non silvofishery, which means silvofishery is more profitable than non silvofishery. Silvofishery and non silvofishery pond sufficiently provide high annual revenue for domestic fish farmer/tenants. The amount of the revenue is 65.83% for silvofishery and 55.44 % for non silvofishery. Key words : financial analysis, silvofishery, non silvofishery, household income
