Judul: Studi Nilai dan Distribusi Biodiversitas di Daerah Aliran Sungai (DAS) Ciliwung Hulu
Abstrak: Watershed is one of the ecological boundary that has important role related to landscape sustainability. Ciliwung Watershed is categorized as super-priority watershed in Indonesia and provides landscape services particularly mentioned in this study is biodiversity value. The study sites were located in three sub-districts in the upper stream of Ciliwung Watershed (Ciawi, Megamendung, Cisarua), Bogor District of West Java. The main objectives of this study were to analyze value and distribution of biodiversity using six indicators of landscape sustainability. The six indicators (presence of threatened species, land use and land cover change, land use intensity of organic agricultural, population, occupation, and infrastructure) were analyzed using geographical information system (GIS). Based on the result, it can be shown that Cisarua and Megamendung sub-district are the first and second largest area with high biodiversity value (4 022 ha and 2 099 ha). Meanwhile, Ciawi sub-district has no area with high biodiversity value. Finally, we propose six recomendations of landscape management for biodiversity sustainability in the upper stream of Ciliwung Watershed.

Judul: Studi Karakteristik Permukiman di Daerah Aliran Sungai (DAS) Ciliwung Hilir
Abstrak: Ciliwung Watershed is one of watershed that across the Jakarta capital region. Ciliwung Watershed is categorized as super-priority watershed in Indonesia. The study was conducted in down stream of Ciliwung Watershed in Jakarta. The main objectives of this study were to analyze land cover changes, and to analyze characteristics of settlement in down stream of Ciliwung Watershed. Data were analyzed using Geographical Information System (GIS). Based in the result, it can be shown that land cover changes from green open space to built up area occured in down stream of Ciliwung watershed (70.07%). The settlement is dominated by the unplanned settlement (87.23%). The charactristics of the unplanned settlement are linier settlement patterns, very lage size of settlement, low to medium building density, and good condition of insfrastructure. Five recommendation have provided for landscape managing of settlement in down stream of Ciliwung Watershed.

Judul: Apatite Growth Optimation on Chicken Mucouse by Fourier Transform Infrared (FTIR) Characterization
Abstrak: Some experiment had been conducted to grow apatite from supersaturated solution of calcium phosphate ions on chicken mucouse. The calcium and phosphate ions were originated from Ca(NO3)2 and (NH4)2HPO4. Carbonate ions from (NH4)2CO3 was also used as starting solution. Experiment was carried out within about 5 hours at temperature 370 C and pH 7. Value of Ca+ : PO4 3- was 1.67, while molar ratio of CO3 2- : PO4 3- was 0.5 : 1. Molarity of molar ratio CO3 2- : PO4 3- variated approximately 0.15 : 0.30, 0.51 : 1.02, and 0.90 : 1.80. Mass of mucouse powder was constant 0.75 gram. The analysis result of Fourier Transform Infrared (FTIR) showed that the precipitation was apatite carbonate type A and B. In these experiment it was found out that the mucouse reduce the crystallinity of apatite precipitant, and the growth of apatite crystal was optimum at solution with molar ratio CO3 2- : PO4 3- about 0.15 : 0.30.
