Judul: Kemunduran mutu ikan nila (Oreochromis niloticus) pada penyimpanan suhu rendah dengan perlakuan cara kematian dan penyiangan
Abstrak: Perkembangan industri hasil perikanan yang semakin maju menharuskan bahan bakunya mempunyai mutu yang baik dengan kandungan gizi yang tinggi. Bahan baku hasil perikanan dengan mutu baik dapat diperoleh jika penanganan dilakukan dengan baik. Penanganan yang dilakukan oleh nelayan dan penjual pada kenyataannya masih belum sesuai standar penanganan nasional (SNI). Para penjual ikan masih mengabaikan aspek sanitasi dan higien yang dapat menyebabkan kontaminasi pada ikan. Oleh karena itu dilakukan kajian tingkat kesegaran ikan dengan perlakuan cara mati adn pembuangan isi perut pada penyimpanan suhu chilling (0-5 derajat celcius). penelitian ini bertujuan untuk mengetahui rendemen, kandungan gizi, serta tingkat kesegaran ikan nia melalui uji subyektif dan obyekyif (TPC, pH dan TVB)

Judul: Kemunduran Mutu Ikan Nila (Oreochromis niloticus) dengan Perlakuan Cara Mati dan Penyiangan selama Penyimpanan
Abstrak: Kemunduran mutu ikan dapat dihambat dengan memberikan beberapa teknik penanganan, di antaranya adalah penanganan dengan perlakuan cara mati dan penyiangan dengan penyimpanan suhu rendah. Penelitian ini bertujuan mengevaluasi kemunduran mutu ikan nila dengan perlakuan cara mati dan penyiangan melalui uji organoleptik, TVB, dan pH selama penyimpanan dingin. Hasil analisis asam amino terdapat 16 asam amino yang terdiri dari 9 asam amino esensial dengan total 34.9% dan 7 asam amino non esensial dengan total 28.68%. Hasil uji organoleptik menunjukkan perlakuan mati cepat disiangi adalah perlakuan yang paling baik karena memiliki penurunan mutu yang paling rendah. Hasil uji TVB juga menunjukkan perlakuan mati cepat disiangi merupakan perlakuan yang paling baik karena memiliki kenaikan nilai paling sedikit. Ikan nila masih dalam batas kesegaran pada hari ke-8 dan perlakuan penyiangan adalah perlakuan yang paling optimal dalam menghambat kemunduran mutu ikan nila pada penyimpanan dingin.

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
