Abstract

Kawasan suksesi alami pada area pengendapan tailing Tanggul Ganda berpotensi besarsebagai sumber cadangan karbon. Estimasi stok karbon biomassa vegetasi hutan suksesi alami TanggulGanda telah dilakukan selama Pebruari-Mei 2010.Sampel tumbuhan bawah dan serasah diambil dari 7blok yang masing-masing terdiri atas 6 sub plot. Hasil analisis memperlihatkan bahwa stok karbon dikawasan suksesi alami blok B4BL dan B5BL adalah 38,84 ton/ha berasal dari 23,87 ton/ha tumbuhanbawah dan 5,9 ton/ha serasah. Stok karbon di blok B1BB, B4BB, B9BB, B10BB, dan B12BB adalah112,4 ton/ha berasal dari 98,6 ton/ha tumbuhan bawah 13,81 ton/ha serasah. Nilai biomassa dan stokkarbon serasah yang lebih rendah dari tumbuhan bawah diduga berkaitan dengan proses dekomposisibahan organik yang berlangsung lebih cepat pada serasah. Setiap vegetasi menghasilkan kualitasbiomassa yang berbeda. dan sisa biomassa menjadi sumber bahan organik yang dapat dimanfaatkanuntuk memperbaiki kualitas tanah.

Abstract

The fragmentation of forest vegetation cover can be measured quantitatively, using tools that can characterize the geometry and spatial properties of the patch or patches of mosaic, which depicts the forest loss and the changes in the temporal pattern.   The aims of this paper are to observe the process of the forest fragmentation, to find out the changes of spatial patterns of habitat continuum by applying the spatial dynamics change analysis of the forest fragmentation phases, and to provide the comprehensive approach in determining the rapid change of the forest landscape structure in the spatial transformation process, based on the decision tree models.  We find three phases of the forest fragmentation were identified, namely dissection, dissipation, and attrition.  This study shows that the production forest area and a wildlife conservation area that contiguous or borders, has the same phases in the process of fragmentation of the forest, but both have a difference of the magnitude of forest loss.  We find there are at least five effects of forest fragmentation to the landscape structure, those are  increasing in a number of habitat patches, decreasing in a size of habitat patches, reduction in a habitat amount, increasing in a dispersion and interspersion of patch types, and reduction in a size of spatial connectedness between patches.Keywords: fragmentation, landscape metrics, spatial transformation.

Abstract

The research on the utilization of solid waste (fly ash) has been conducted to avoid the further effect of microbial and of the municipality solid waste in the wetland ecosystem. The purpose of this research is to utilize the fly ash, the solid waste of the PLTU industry, as protective layer (geosynthetic liners/GCLs) at waste disposal areas in order to avoid microbial and chemical pollution to the environment. During the research, ponds with 6x6x4 m in size was added with GCLs (layer of 30 sacs of fly ash 25 kg/sac at each 2 meters of pile waste) and a control pond. The result shows that fly ash with the composition of SiO2 (42,92 %) and AlO2  (29,45%) can be utilized as a protective layer (geosynthetic liners), because after 3 weeks it can minimize the contamination of bacteria (total decrease of coliform bacteria > 50%) to the environment, and also reduce some toxic compound, especially heavy metal such as Pb (30,1%) and Cu (43,54%), and the content of nitrate (32,1%). Hence fly ash has economic and ecological values as a protection layer at the solid waste disposal area to avoid the environmental contamination of bacteria’s and chemicals.

Abstract

Phytoplankton have important as food-chain major component and primary production of marine environment. However, high abundance of phytoplankton could give harmful effects toward water ecosystem. Moreover, they could produce toxic substances that will be accumulated within their consumer. This accumulation could be dangerous for human or animals.This research were aimed to determine and calculatespecies of harmful algae in Banyuasin coastal waters. The study was conducted on April, June, August, October and December of 2013, and in February 2014, at ten stations. Phytoplankton samples were taken vertically using plankton nets. In the form of cone-shaped with a diameter of 30 cm, length 100 cm and mesh size 30 ?m.The result showed that there are 35 genera of phytoplankton. That have been found and consisted of four groups; Bacillariophyceae, Dinophyceae, Cyanophyceae and Chlorophyceae. 13 species were identified as Harmful Algal (Chaetoceros, Coscinodiscus, Nitzschia, Skeletonema, Thalassiosira, Alexandrium, Ceratium, Dinophysis, Noctiluca, Protoperidinium, Prorocentrum, Anabaena dan Oscillatoria), with seven of them were known for having toxin (Nitzschia, Alexandrium, Dinophysis, Protoperidinium Prorocentrum, Anabaena and Oscillatoria). Monitoring result showed that the highest number of species of potential harmful algal blooms (HABs) occured in June and the highest abundance occured in August, especially Chaetoceros and Skeletonema.How to CiteAryawati, R., Bengen, D.
