Judul: Pengaruh Zeolit terhadap Kelangsungan Hidup dan Pertumbuhan Udang Windu (Penaeus monodon Fab.) di Tambak
Abstrak: Penelitian ini di1akukan dengan tujuan mengetahui pengaruh zeolit Bayah pada empat tinglcat dosis yang berbeda terhadap ke1angsungan hidup dan pertumbuhan udang Windu (nep~eus monodon Fab.) di tambak. Rancan§an percobaan yang digunakan adalah rancangan acak lengkap dengan empat per1akuan dan tiea u1angan. Perlakuan tersebut adalah: per1akuan A (tanpa zeolit atau kontro1), per1akuan B (pemberian zeolit dengan dosis 4 ppm per hari) , per1akuan C (pemberian zeolit dengan dosis 8 ppm per hari) , perlakuan D (lJembel'ian zeolit dengan dosis 12 ppm per hari).

Judul: Pengaruh penambahan zeolit kedalam makanan buatan terhadap pertumbuhan udang windu
Abstrak: Dalam menghadapi kendala pada teknik budidaya intensif, yaitu mahalnya harga makanan buatan, maka makanan buatan yang dapat meng- hasilkan peningkatan pertumbuhan dan efisiensi makanan dinilai dapat menguntungkan secara finansiil. Penambahan batuan mineral zeolit pada ransum ternak dapat menghasilkan peningkatan pertumbuhan, efisiensi makanan, kelangsungan hidup dan penurunan terjadinya ganggung pencernaan. Penelitian dengan tujuan melihat pengaruh penambahan zeolit bayah kedalam makanan buatan TIR-Feed terhadap pertumbuhan udang windu (P. monodon) telah dilakukan di Lab. Proyek Pandu Tambak Inti Rakyat Karawang dari tanggal 1 April 1988 sampai tanggal 10 Mei 1988. Konsentrasi zeolit yang dipakai adalah 0% (perlakuan A), 2% (perlakuan B), 4% (perlakuan C), dan 6% (perlakuan D). Formula makanan yang dipakai berdasarkan Formula TIR-Feed. Makanan dibuat dengan bentuk butiran (crumble) dan diberikan 4 kali sehari yaitu pk 06 11, 15, dan 20 sebesar 20% bobot biomassa/hari. Pemeliharaan dilakukan pada 12 buah akuarium kaca berukuran 80 x 40 x 60 cm dengan menggunakan media air laut bersalinitas 25 per mil dengan kedalaman 30 cm. Udang uji yang digunakan adalah udang windu (P. monodon) stadia post larva 30 yang ditebar dengan kepаdatan 45 ekor/m². Lama pengamatan yang dilakukan 40 hari dan penimbangan bobot biomassa dilakukan setiap 10 hari.

Judul: Development of Face Recognition Model using Bi-2DPCA and Support Vector Machine
Abstrak: The human face is always used in the application of access control systems, identity authentication systems, surveillance systems and security systems. Some researh on face recognition has been proposed with a variety of methods, such as Eigen Faces, Fisher’s Linear Discriminant, Bayesian Networks, Neural Networks,Hidden Markov Model, and so on. But all the above mentioned methods have limitations, such as dealing with the size of the image and lighting and learning time are too long. In a study to obtain an alternative method for face recognition, Le TH and Bui L (2011) conducted research model of face recognition with Two- DimensionalPrincipal Component Analysis (2DPCA) and Support Vector Machine (SVM) using AT&T face image data. The results of these studies that the accuracy of face recognition use 2DPCA and SVM was 97.3% and PCA-SVM was 95.2%. Then in 2010, Bi-2DPCA uses as alternative method of face recognition performed by Yang J et al. (2010). In a study comparing methods of Bi-2DPCA, 2DPCA and PCA. The conclusion that the use of Bi-2DPCA generating and computational accuracy was better than 2DPCA and PCA Based on research conducted by Le TH and Bui L (2011) and Yang J et al. (2010), conducted research for the development of models of face recognition using dimension reduction technique Bi-2DPCA and Support Vector Machine (SVM) as pattern recognition. 1DPCA and 2DPCA dimension reduction technique are used as comparison measure dimensions and computing time than using Bi-2DPCA technique. To help SVM in recognizing human faces, SVM use linear, polynomial and radial basis function (RBF) kernel function. When using RBF kernel, used for the RBF kernel, the parameter for sigma is 2-15 up to 23 and the value of C starting from 2-5 up to 214 which have been used in a study conducted by Le TH and Bui L (2011). Facial image data used are taken from the ORL Face Database AT&T Laboratory, which contain 40 faces, each face with 10 images, and total of image 400 pieces. Validation is done by Leave-One-Out (LOO) cross validation, so that for each pair of extraction and classifier method is 10 trials. One against all method used to help SVM in classifying the ORL face data consists of 40 classes, to reduce the computational time. From the results of tests on 36 models of face recognition , Bi-2DPCA85% with the help of a linear kernel generates the highest level of face recognition accuracy of 94.25 %, and the lowest accuracy rate of 24.50 % was obtained with 1DPCA-kernel polynomial ordo 3 . While the lowest computational time of 15.34 seconds when component is used by 85 % computation time and a maximum of 252.68 seconds when component is 95 %. There are several things that could be concluded that: pattern accuracy on each kernel feature extraction are the same. This means that there is no relationship between the feature extraction used by the kernel to the SVM. The second is, in this study SVM cannot classify large dimension data. From the results of tests on 36 models of face recognition, Bi2DPCA85% with the help
