Researches on the spatial distribution of sediment characteristics and community structure of macrozoobenthos have been executed on November 17th to 20th 2009 in Kuala Sugihan estuaries. The purpose of this study is, to measure water quality, study the spatial distribution of sediment characteristics, knowing the structure of macrozoobenthos communities and study the spatial distribution of macrozoobenthos in estuaries Kuala Sugihan. Data analysis was done of macrozoobenthos community structure analysis performed by determining the value of diversity index (H'), uniformity index (E) and dominance index (C) species. The research that physical-chemical water parameters measured showed values that are still at the threshold quality standard that allowed for marine life (KLH Ministerial Decree No. 51 of 2004). Caracteristics (physics-chemistry) in estuarine sediments Kuala Sugihan showed that sediment texture of clay to the clay berliat and dusty clay is a suitable habitat for life and affect the density of macrozoobenthos and species composition of each observation station. Macrozoobenthos found in estuarine waters of Kuala Sugihan as many as 21 species included in four classes Polychaeta (nine species), gastropods (nine species), Bivalvia (2 species) and crustaceans (one species). Diversity index (H') at the study sites were the highest 3.238. Station 1 is located on the inside of the mouth is found only one type of spatial Polychaeta.

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.

The analysis relationship of Spirulina sp medium with chemical composition has been conducted. Chemical analysis was performed using X-Ray Fluorescence analysis. Furthermore, potention of Spirulina sp as adsorbent of metal ions was analyzed using FTIR spectroscopy. The results showed that metals such as Zn, Fe, Mn, Ca, Cu, and Mo were mainly metals in Spirulina sp. These metals were not correlated with cultivated medium of Spirulina sp. Analysis of potention Spirulina sp as metal ions adsorbent showed that Spirulina sp has functional groups –C=O and –OH as ligand. Intercation of metal ions Cu(II) and Cr(III) with Spirulina sp indicated that metal ions bond to –C=O functional group.Keywords: Spirulina sp, media composition, chemical content, metal ion, adsorptionAbstrak (Indonesian): Telah dilakukan analisis hubungan komposisi media Spirulina sp dengan kandungan kimia yang dimilikinya.

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.
