Judul: Sistem Identifikasi Kayu Ramin Berbasis Citra Menggunakan Local Binary ------- Pattern dan Probabilistic Neural Network
Abstrak: The purpose of this research is to create dekstop application system in effective and efficient way to identify the ramin wood and similar ramin wood based on imagery by using LBPV and PNN methods. LBP variance (LBPV) is used to characterize the local contrast information into the one-dimensional LBP histogram. This research uses the Probabilistic Neural Network (PNN) technique to classify the LBPV. This research was carried out using 21 different types of similar ramin wood and one species of ramin wood. For each type of wood, 20 image were collected. The results of this research conclude that of the 3 operators used one operator was obtained that produce the highest accuracy, which is LPBV (24,3) with 79,77% accuracy. The result of this research indicate that LBPV (24,3) is more accurate to distinguish ramin wood texture and similar ramin wood. This research used only a small-size database, so for further research is needed to use more feature extract methods and types of ramin wood and similar ramin wood

Judul: Wood Type Identification Using Support Vector Machine Base on Image Data
Abstrak: The wood type identification can be studied as a science, but the ability to identify the type of wood can only be obtained through a long training process, repeatedly and continuously. The problems that appear when workers are not skilled enough to identify the type of wood are the longer time of business process, and thus certainly will added more cost. The wood type identification system is very necessary to provide an alternative solution for this problem. The wood samples had obtained from Balai Pemantauan Pemanfaatan Hutan Produksi Wilayah XII Palangka Raya, which is consists of 4 types of wood, namely: Johar, Jati, Rasamala and Sengon wood. The image of wood type data has obtained using a microscopic camera, and each type has 24 images. Total data in this study are 96 images with has an initial size 480 x 640 pixels and converted into 96 x 128 pixels size. This RGB sample data image is converted into a grayscale images. The image processing in this study using Two - Dimensional Principal Component Analysis (2D-PCA) feature extraction method, which is serves to reduce the images dimensions without removing the important information. The Support Vector Machine (SVM) with kernel function Radial Basis Function (RBF) and polynomial kernel method has been used for classification process. The highest accuracy results which obtained using the RBF kernel at sigma parameter ( ) 35, 40, 45 and 50, within 60% feature extraction are 94.79%. The highest accuracy level which obtained using the polynomial kernel within 1 parameter order and 60% to 75% feature extraction are 95.83%. The results showed that the feature extraction using polynomial kernel produces a higher accuracy than the RBF kernel method.

Judul: The Change of Family's Milk Consumption during Monetary Crisis
Abstrak: Krisis Moneter yang terjadi di negara kita sejak Juli 1997 lalu menyebabkan harga kebutuhan pokok yang melambung, salah satu diantaranya aclalah kenaikan harga susu. Dengan terjadiuya kenaikau harga susu ini maka terclapat keluarga-keluarga yaug melakukan perubahan kousumsi susu keluarganya. Merupakan ha! yang menarik untuk melihat perubahan pola konsumsi susu yang terjadi clan jenis susu yang seperti apa yang banyak mengalarni perubahan. Dengan melakukan smvei kepacla keluarga-keluarga yang banyak mengkonsumsi susu, yaitu keluarga yang mempunyai anak usia sekolah, clan keluarga yang berasal clari golongan penclapatan menengah, maka akan clapat memberikan gambaran perubahan konsumsi susu keluarga yang terjadi. Dalam masa krisis moneter, maka sebanyak 38.8 % clari 227 responden mengurangi konsumsi susunya dengan sebesar 8.4 % menghentikan konsumsi susunya. Terclapat sebanyak 6.6 % keluarga yang menukar jenis susu yang dikonsumsinya. Konsumsi susu lebih dipentingkan untuk golongan usia balita, dimaua pacla golongan usia ini persentase banyak balita yang tetap konsumsi susunya lebih bcsar dibaudingkan dengan golongan usia anak clan dewasa. Sebagian besar keluarga yang mengurangi konsumsi susunya merupakan keluarga yang mengalami penurunan penclapatan. Jenis susu yang paling peka terhaclap krisis moneter aclalah jenis susu cair dimana jenis susu ini paling banyak persentase keluarga yang mengurangi yaitu sebesar 45.8 %, dibandingkan dengan jenis susu bubuk, kental clan murni. Sedangkan jenis susu kental merupakan jenis susu yang tidak terlalu peka terhaclap krisis moneter dimana jenis susu ini persentase keluarga yang tetap clan naik konsumsi susu kentalnya paling besar, yaitu sebesar 67.1 %.
