Judul: Evaluation of healthy and environmentally sound housing in the upper stream of Ciliwung river basin, West Java
Abstrak: Penelitian ini dilaksanakan pada bulan Maret hingga September 2007 di Hulu Daerah aliran sungai (DAS) Ciliwung, berada di wilayah Kabupaten Bogor dan sebagian Kota Bogor di ketinggian 300 m sampai >1000 m dpl. DAS Ciliwung Hulu merupakan daerah konservasi dan hutan lindung yang harus tetap dijaga kelestariannya. Pertumbuhan jumlah penduduk di DAS Ciliwung Hulu di ikuti dengan kebutuhan akan lahan perumahan. Hal ini menyebabkan terjadinya alih fungsi lahan dari lahan pertanian ke lahan perumahan. Perumahan adalah kelompok rumah yang berfungsi sebagai lingkungan tempat tinggal atau hunian yang dilengkapi dengan sarana dan prasarana lingkungan untuk menunjang kehidupan. Perumahan sehat merupakan konsep dari perumahan sebagai faktor yang dapat meningkatkan standar kesehatan penghuninya yang pendekatannya berorientasi pada kualitas lahan, lokasi bangunan, dan kualitas lingkungan. Oleh karena itu, pengembangan lahan perumahan harus memperhatikan kesesuaian lahan agar fungsi DAS bagian hulu sebagai kawasan konservasi tanah dan air tetap terjaga.

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: Graphology Analysis Based on Letter a and t Using Perceptron.
Abstrak: Graphology or handwriting analysis is a method of identifying, analyzing, evaluating, and understanding personality through the strokes and patterns revealed by handwriting. A person who can analyze handwriting is called a graphologist. A graphologists can be subjective in their assesments different graphologist can have different analysis of the same handwriting. Therefore, a computer technology may help to minimize the subjectivity. This research used perceptron to analyze personality based on handwriting. Perceptron is one method of neural network. This research analyze two letters to letter a and t image. Letter a are represented by 135 images, consisting of 81 images as training data and 54 images as testing data. There are 150 images used for t images, consisting of 90 images as training data and 60 images as testing data.There are 5 experiments consisting of 2 experiments for letter a and 3 experiments for letter t. The result is the character of each class letter a and t where each parameters there are 3 classes. The accuracy of letter t and letter a was 55% and 88.89% respectively.
