Judul: Metode hough transform untuk ekstraksi ciri bentuk pada citra bunga
Abstrak: Ekstraksi ciri merupakan suatu proses yang sangat penting dalam proses temu kembali citra berbasis informasi seperti warna, bentuk dan tekstur. Penelitian ini mengimplementasikan metode Hough transform untuk mengekstraksi ciri bentuk citra bunga melalui dua pendekatan yaitu lingkaran dan elips. Penelitian ini juga menggabungkan ciri bentuk hasil dari Hough transform dengan ciri warna pada citra menggunakan metode fuzzy color histogram (FCH) di dalam proses temu kembali. Penelitian membandingkan hasil temu kembali metode Hough transform dengan penambahan ciri warna dari FCH. Evaluasi terhadap hasil temu kembali dilakukan menggunakan rataan precision untuk setiap tingkat recall. Berdasarkan penelitian ini, metode Hough transform menggunakan pendekatan lingkaran memiliki hasil temu kembali dengan rataan precision mencapai 26%. Metode Hough transform menggunakan pendekatan elips memiliki rataan precision mencapai 23%. Penambahan ciri warna FCH 25 bin dapat meningkatkan rataan precision hingga dua kali lipat. Metode Hough transform lingkaran dengan FCH memiliki rataan precision mencapai 44% dan untuk Hough transform ellipse mencapai 46%.

Judul: Ekstraksi ciri morfologi (panjang dan lebar fisiologis) dan tekstur untuk temu kembali citra helai daun
Abstrak: In recent time, the ability to identify and classify leaves becomes a great need for taxonomist to know the diversity of plants (Hickey et al 1999). Identification can be done by identifying features of morphology and texture of the leaves or also with a combination of both. Annisa (2009) implemented the feature extraction approach to obtain the basic characteristic morphological image derived from the leaf blade and the co-occurrence matrix for texture feature extraction. Morphological features that obtained were diameter, leaf area, leaf perimeter, smoothing factor, form factor and perimeter ratio of diameter. Texture features were obtained energy, inverse difference moment, entropy, maximum probability, contrast, correlation, and homogeneity. This study used morphological features approach to obtain morphological features and co-occurrence matrix for texture features. Therefore, the evaluation of image retrieval was done by using more complete morphological features with additional morphological features of physiological length and physiological width. Both morphological features are very useful to help identify the characteristics of a leaf blade. This research approach has been successfully implemented morphological features. Value of image retrieval evaluation leaves increased with the addition of two morphological characters. In this research, with additional morphological features and physiological length and physiological width resulted in morphological traits 0.2083, the texture feature values 0.1864 and character of Bayesian Network 0.2055. So that the average value of precision increased by 0.0137 for morphological features and by 0.0069 for combined value of morphological and textural characteristics (Bayesian Network).

Judul: Sarcosporidiasis in slaughter animals
Abstrak: Sarcocystis which belong to the generally occuring parasites for they are found almost all over the countries of the world. Infection of Sarcocystis usually throught inges- tion of feces or flesh of infected animals. The pathogenesis of Sarcosporidiasis is considered as benign but when the Sarcocystis die in a host, sarcocystin or sarcosporidin is liberated thereby which lead to condemnation of meat in the abattoir. Besides condemnation of meat, Sarcocystis also causes: loss of appetite, anemia, lameness, weakness in the lion, diarrhea, fever, pyrexia, paralysis, emaciation, neuro logical disturbances, etc. " Amprolium "at the rate of 100 mg/Kg body weight per day has been practiced for prevention or to minimize Sarco- sporidiasis. Treatment must be started during incubation period. Shedding of Sarcocystis sporocysts in the feces of carnivores is the key factor in the spread of Sarcocystis infection. Therefore, control efforts must be based primarily on measures designed to break the cycle of Sarcocystis.
