Judul: Simulasi Formasi dan Dinamika Laju Aliran Hulu Sungai Cisadane Berdasarkan Prinsip Active-Walker
Abstrak: Active-walker is the principle of self-organization of agents involved in a system. If the agents move from one state to another then the landscape will change and these changes will determine the chosen next step. This principle is able to explain and model the formation and dynamics of the river flow speed. The calculation of the flow speed uses the basic principles of physics, namely the Newton's Law of mass-momentum conservation and the addition of velocity vectors under the influence of gravitational force. By means of the corresponding conservation of mass-momentum it can be obtained a result which is in a good agreement with the field survey data. Similar result is also found by using a model of the velocity vector addition. But the later model does not describes the real physical condition

Judul: Simulasi Dinamika Aliran Sungai Ciliwung Hulu Berdasarkan Prinsip Active-Walker
Abstrak: Active Walker ( AW ) is agent based modeling where walker as an agent change its environment when it runs , and the next step is influenced by the changing environment. In this study, modeled the dynamics of the Ciliwung River upstream based on active walker principle. This model use DEM SRTM data that has a spatial resolution of 90 m x 90 m and 15 m x 15 m. The data were processed using ArcGIS 9.3 software to view elevation data points of each river. The elevation data are used as landscape in Ciliwung river upstream model based on active walker principle. This model also uses a data of flow, width and depth of the river were obtained from field survey. From this research, we concluded that river of Gunung Mas has influence on the end speed of Katulampa’s dam than river of Katulampa. This simulation has similar characteristics of river flow with state of Upper Ciliwung so the AW principle can be used for modeling the Ciliwung river upstream .

Judul: Enrichment of organic selenium, inorganic selenium and  vitamin E in quail products through its supplementation in the diet and its potency  of quail eggs as an ingredient in selenium-rich egg juice
Abstrak: This study was aimed to achieve an optimum level of combine organic selenium, inorganic selenium and vitamin E in obtaining the best production and reproduction as well as the highest level of selenium in quail eggs. This study was conducted from January to August 2008. Numbers of observed quails were 720 (360 females and 360 males). The treatments were applied when the quails were six weeks old. Nine treatment diets were: To (commercial diet), T1(0.46 ppm inorganic Se + 43.50 ppm vitamin E), T2 (0.46 ppm inorganic Se + 87.00 ppm vitamin E), T3 (0.92 ppm inorganic Se + 43.50 ppm vitamin E), T4 (0.92 ppm inorganic Se +87.00 ppm vitamin E), T5 (0.46 ppm organic Se + 43.50 ppm vitamin E), T6 (0.46 ppm organic Se + 87.00 ppm vitamin E), T7(0.92 ppm organic Se + 43.50 vitamin E) and T8(0.92 ppm organic Se + 87.00 ppm vitamin E).
