Abstract

The biodiversity conservation areas of Cirebon quarry, in this case Blindis and Sari mountains is a limestone ecosystem.Limestone ecosystems play an important role in climate regulation. Quantifying the organic carbon storage of limestoneecosystems in this area definitely helps to evaluate the roles of these ecosystems in both global and regional carbon cyclesand also their impact on climate. This research was carried out to know the complete data of carbon storage in Cirebonquarry on each ecosystem types. In deep, it will give information which ecosystem and carbon pool that contributes thehighest carbon stock. The carbon stock calculating methods in above-ground was based on RaCSA (Rapid Carbon StockAppraisal) methods. Based on the observation, there are three ecosystem types in Cirebon Quarry i.e. Opened Area, ThickBushes and Secondary Forest. The result showed that Secondary forest had the highest total C-stock which was 87.18 t Cha-1, while the C-stock on Thick Bushes and Opened Area were 42.95 and 17.92 respectively. The total C stock inbiodiversity conservation area of Cirebon Quarry was 148.05 t C ha-1 comprises 48% of C plant biomass and 52% of Csoil.Key words: carbon stock, Cirebon quarry, limestone area

Abstract

East Nusa Tenggara located in the Wallacea area that has many endemic species. However, the existence of germplasm diversity in this area has been threatened due to landscape changes and deforestation. The research was conducted to identify floristic composition in Sikka forest area. This research also aimed to compare that plant composition in Sikka forest area on each of the different altitudes, including their diversity richness and environmental factors. Two sampling methods were used, which are Point-Centered Quarter (PCQ) method that applied for trees and nested sampling method 5x5 m2 for sapling and 2x2 m2 for ground cover. Measured parameters were Relative Density (RD), Relative Frequency (RF), Relative Coverage/dominance (RC), Important Value Index (IVI), Diversity Index (H'), and Jaccard Similarity Index (J’). Research results showed that the diversity index of each region was relatively low. Plant composition of tree, sapling, and groundcover in three different altitudes was quite different. This result indicates that the plant composition in the Sikka, East Nusa Tenggara is very diverse. The temperature and relative humidity in each altitude area observed was significantly different. One of the endemic species of Flores Island, Eucalyptus urophylla, was only found at 500-700 m asl. There are very limited research on the vegetation diversity held in Flores, East Nusa Tenggara. This research can be the basic for further research in order to explore the potential diversity of flora in this area.

Abstract

The hydrological performance of individual tree can be estimated by measuring the stem flow, throughfall and rainfall interception. Water distribution through tree canopy is affected by tree architectural model and another tree’s morphology. This research was done in order to predict the most appropriate tree species that is suitable on soil and water conservation. This research was conducted in Purwodadi Botanic Garden during the rainy season on January 2014 to March 2015, in order to examine the interception rate, throughfall and stemflow on some selected local plants i.e Syzygium polyanthum, Diospyros blancoi, Schleichera oleosa, Madhuca longifolia, and Canarium vulgare. Other observation that support the data, was also measured i.e. Leaf Area Index (LAI), crown depth, leaf size, Diameter of Breast Height (DBH), and height of tree on each species. Results showed that Diospyros blancoi has the highest interception value, which is 53 %, followed by C. vulgare 47.4%, S. oleosa 46.9 %, M. longifolia 38.6%, and S. polyanthum 35.6% respectively. Under the heavy rain, D. blancoi, which has the highest LAI value, also showed the best performance in the rainfall interception value and showed significantly different among others. Canopy interception and stem flow is related to rainfall, the higher the rainfall, the higher the throughfall and the stemflow among species. Morphology on each species, gives the different effect on their partitioning rainfall value.
