Judul: Pemodelan Support Vector Machhine Untuk Identifikasi Jenis Tanaman Paku Berdasarkan Citra Spora Dalam Ruang Eigen
Abstrak: Spores of is a breeding tool of ferns plant (Pteridophyta), which generally exist beneath the surface of each leaf. The research of Pteridophyta spores characteristic which commonly done is observing the size and shape to see what kind of spores. The method requires a lot of comprehension, experience, accuracy and time to achieve high accuracy in the determination of the type. Based on this reason, it is necessary to develop another technique by modeling to help identify the type Pteridophyta on the spore part. The purpose of this study is to make Support Vector Machine (SVM) modeling to identify the types of ferns by spore image in the eigen space. The data used was the image of the spores with four classes, each has 24 data per class. The method used in this study was the 2D-PCA for feature extraction and SVM for classification of data by using RBF and polynomial kernel functions. The result of this study is the accuracy of any extraction that has been attempted. The best result lies in the RBF kernel function with feature extraction of 70% and parameter 10 with an accuracy of 98.96%.

Judul: Analisis Kinerja Support Vector Machine (SVM) Dan Probabilistic Neural Network (PNN) Pada Sistem Identifikasi Tumbuhan Obat Dan Tanaman Hias Berbasis Citra
Abstrak: This research analyzed perfomance of clasification for plant identification using Support Vector Machine (SVM) and Probabilistic Neural Network (PNN). In this research we used kernel linear, polynomial and RBF for clasifier SVM. In thus research, we use 1.440 medicinal plant images and 300 house plant images belong to 30 are extracted using Fuzzy Local Binary Patern based on texture feature.The expermental result shows that SVM kernel polynomial is superior compare to PNN with accuracy 73.57% to medicinal plant identification and SVM kernel RBF is superior compare to PNN with accuracy 81.11% to house plant identification. The proposed system is promising to improve identification medicinal plant and house plant.

Judul: Enteric Collibacillosis Pada Anak Babi Baru Lahir: Patogenesa dan Perubahan-Perubahan Patologisnya
Abstrak: Diare disebabkan oleh infeksi bakteri Escherichia coli pada anak-anak babi baru lahir yang peka terhadap en terotoksin produk bakteri tersebut. Dikenal sebagai colibacillosis. Patogenesa dari colibacillosis anak babi baru lahir adalah (1) infeksi oleh E. coli patogen, (2) proliferasi E. coli di lumen usus halus, (3) produksi dan pelepasan enterotoksin, dan (4) aktifitas toksin pada usus halus. Dalam proses proliferasi, adanya antigen pili K88 sangat penting karena memungkinkan bakteri perlekatan dengan epitel mucosa usus halus. mengadakan Setelah ko lonisasi dan proliferasi segera toksin dilepaskan. Akti- fitas toksin menginduksi sekresi yang berlebihan dari u- sus sehingga banyak cairan yang dikeluarkan ke lumen usus. Hal ini mengakibatkan banyak cairan dan elektrolit hilang sehingga timbul diare, dehidrasi dan asidosis yang sering menyebabkan kematian. Perubahan-perubahan patologis yang umum adalah dis tensi usus halus, dilatasi lambung dan infark pada kurva- tura mayor. Perubahan-perubahan histologis yang terjadi adalah enteritis hemorrhagica acuta, oedem dan kongesti pembuluh darah di lamina propria, akumulassi leukosit inti polimorf, sel monosit, dan inti sel mengalami piknosis Thrombus pada vena dan degenerasi serta desquamasi sel epitel usus….
