Abstrak: The degradation of tropical browse plants in different fermented media rumen fluid had been determined in this experiment. The fermented media was collected from sheep which was obtained feed containing saponin and mix between saponin and tannin. The experimental design for in vitro was Factorial Randomized Block Design 9x3x2 with 3 replications. The first factor was nine kinds of tropical browse plant. The second factor was rumen fluid from sheep which fed with mixed grass (MG) (B1) , MG + saponin (B2) and MG + saponin + tannin (B3) and the third factor was with and without polyethylene glycol (PEG). The experimental design for in sacco was Factorial Randomized Block Design 9x3 with 2 replications. The first and second factors were similar to in vitro experiment. Variables observed were in vitro gas production, in vitro and in sacco dry matter degradation. The data were analyzed by Analysis of Variance, and differences among treatments were examined by Duncan Multiple Range Test. Results showed that difference of rumen fluid had no significant effect on in vitro gas production. In vitro gas production of Pennisetum purpureum and Artocarpus heterophyllus were significantly higher than other tropical browse plants. Rumen fluid containing saponin (P<0.05) significantly increased in sacco dry matter degradation, but there was no significant effect of all treatments on in vitro dry matter degradation. In sacco dry matter degradation of A. heterophyllus was significantly higher than other tropical browse plants but on in vitro, dry matter degradation of A. heterophyllus was similar to P. purpureum. Addition of PEG significantly increased in vitro gas production on B1 and B3, but decreased on B2. Addition of PEG had no effect on in vitro dry matter degradability of nine tropical browse plants.

Judul: Total Produksi Gas dan Degradasi Bahan Kering Hijauan Tropis Pada Media Cairan Rumen Domba yang Diberi Pakan Mengandung Tanin Kajian: In Vitro dan In Sacco.
Abstrak: Hijauan tropis merupakan salah satu bahan yang banyak dimanfaatkan sebagai pakan ternak. Kendala yang dimiliki hijauan tropis sebagai bahan pakan yaitu terkait dengan kadar serat dan anti nutrisi yang cukup tinggi. Salah satu anti nutrisi yang dapat mengikat protein dan mineral adalah tanin. Oleh sebab itu, perlu dilakukan evaluasi nilai degradasi bahan pakan asal hijauan tropis pada media cairan rumen yang hewannya diberi pakan mengandung tanin secara in vitro dan in sacco.

Judul: Identifikasi Karakter Pada Plat Nomor Kendaraan Menggunakan Ekstraksi Fitur ICZ dan ZCZ dengan Metode Klasifikasi K-NN
Abstrak: License plate is a unique code consisting of letters and numbers arrangement. Each vehicle has a license plate that serve as the identity code of the vehicle itself. Since license plates are unique, it often used for recording, such as in the parking area. The character identification characters on the license plates are made automatically using the input in the form of license plate images to facilitate the recording process. K-NN classification and feature extraction ICZ and ZCZ used in the identification of character identification. ICZ and ZCZ feature extraction obtain features by computing the character centroids and divide the image into n equal zones then computing the average distance from the character centroid to every pixel in the image. The character identification accuracy using 14 zones and ICZ are 97.00% while using ICZ+ZCZ feature extraction are 98.17%. The license plate identification accuracy using feature extraction plates ICZ+ZCZ are 72.31% for zero tolerance and 89.23% for one fault tolerance.
