Judul: Efikasi Antibiotik Berbahan Aktif Enrofloxacin terhadap Escherichia coli dan Mycoplasma gallinarum pada Ayam Pedaging
Abstrak: Broiler is a superior breed which has high productivity and shortly in productive period. The productivity of broiler may decline caused by diseases, such as colibacillosis and mycoplasmosis. Antibiotic treatment is one of the choise which can be done to prevent and treat the diseases. This research aims to know the efficacy of antibiotic containing Enrofloxacin against Escherichia coli and Mycoplasma gallinarum. This research was conducted on 1st August, 2012 until 24th August, 2012. The observation included morbidity, mortality, and body weight. The result of this research showed that this antibiotic is effective against Escherichia coli and Mycoplasma gallinarium. The appropriate time antibiotics application to the infected chickens is about six hours untill seven days post infection which has been proven to prevent the diseases effectively.

Judul: Efektivitas antibiotik Enrofloxacin terhadap ayam pedaging yang diinfeksi bakteri Escherichia coli dan Mycoplasma gallinarum
Abstrak: The aim of this study is to determine the most effective time to administer Enrofloxacin to broiler infected with Escherichia coli (colibacillosis) and Mycoplasma gallinarum (mycoplasmosis), in terms of body weight, morbidity, and mortality. This research was held from August 2nd until 24th 2012 in Laboratory Animal Management Unit’s (UPHL) Henhouse, Faculty of Veterinary Medicine, Bogor Agricultural University. The broilers were divided into 2 major groups, the first was infected with Escherichia coli and the second was infected with Mycoplasma gallinarum. Each group were divided into 5 small groups, namely group A (Treatment 6 hours post-infection), Group B (Treatment 3 days post-infection), Group C (Treatment 7 days post-infection), Group positive control (untreated), and Group negative control (not infected, untreated). The treatment is a dose of Enrofloxacin as much as 1 gram in 6 litre of broiler’s drinking water. The parameters observed are bodyweight, morbidity, and mortality. The bodyweight were calculated with Analysis of Variance (ANOVA) method. The results obtained showed that Enrofloxacin is effective if given 3 days post-infection and not effective against colibacillosis.

Judul: Perbandingan SOM dan LVQ pada Identifikasi Citra Wajah dengan Wavelet sebagai Ekstraksi Ciri
Abstrak: Face recognition is one of challenging research topics in computer science because human face is difficult to be modelled. In this research, SOM and LVQ are proposed for frontal face recognition. The purpose is to compare LVQ and SOM based on identification accuracy. Training uses 400 images from 20 different individuals, and the dimension is 180 x 200 pixels. The data are retrieved from University of Essex, UK. Coefficient approximation at Haar wavelet level 6 is used as feature for classification and clustering process. K-fold cross validation with 10-fold is used to divide training and testing data. The experiment is divided into 3 sets, i.e., the experiment using SOM, LVQ, and LVQ initialized by SOM. The highest accuracy achieved by SOM is 97.8974%, while both LVQ and LVQ initialized by SOM achieve 100% accuracy. Based on the accuracy, LVQ proves to be better than SOM for frontal face recognition. This research needs to be improved in order to recognize various poses and changing expressions.
