Abstrak: This research was aimed to determine total gas production and dry matter degradation of fermented tropical browse plants in sheep rumen fluid containing tannins as in vitro and in sacco methods. There were nine types of tropical browse plants, such as Pennisetum purpureum, Brachiaria decumbens, Ciiperus kyllinga, Leucaena leucocephala, Artocarpus heterophyllus , Musa sapientum, Dilenia suffruticosa, Melastoma malabathricum, Sapium baccatum. This research was design using Randomized Completely Block Design Factorial. In vitro experiment and total gas production with 3 factors (9 x 3 x 2) treatment 9 type of tropical browse plants (A), three source of rumen fluids medium (B) such as B1 was control feed, B2 was condenseed tannin treatment and B3 was hydrolizable tannin treatment and with and without Polyethilene Glycol (PEG). In sacco experiment, the design was same with in vitro experiment. Data were analized by analysis of variance (ANOVA) and the differences among treatments were tested by Duncan multiple range test. The parameters observed were total gas production and dry matter degradation. Result showed that Artocarpus heterophyllus has the highest total gas production and dry matter degradation, rumen fluid with contained hydrolizable tannin has the highest total gas production and rumen fluid control has the highest dry matter degradation through in vitro technique and in sacco. There was interaction between rumen fluid with contained hydrolizable tannin with Artocarpus heterophyllus in total gas production and dry matter degradation through in vitro technique and in sacco. Polyethilene Glycol addition caused increasing of total gas production and dry matter degradation through in vitro technique.

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.

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.
