Judul: Penerapan K-Nearest Neighbour untuk Pengenalan Aksara Sunda mMenggunakan Ekstraksi ciri Zoning
Abstrak: Penelitian mengenai pengenalan aksara tradisional sudah banyak dilakukan dengan menggunakan berbagai metode. Salah satu contohnya adalah pengenalan aksara Sunda dengan data tulisan tangan. Penelitian ini dilakukan untuk menentukan akurasi dengan metode ekstraksi ciri Zoning dan Klasifikasi K-Nearest Neighbour. Data yang digunakan pada penelitian ini adalah aksara Sunda tulisan tangan dari 20 responden. Setiap citra dari karakter yang ditulis dirubah menjadi ukuran 120 x 120 pixel. Penelitian ini menggunakan ekstraksi ciri Zoning gabungan ICZ-ZCZ dengan jumlah zona 4, 6, 8, 9, 10, 12, 15, 16, 18, 20 dan 24. Metode klasifikasi yang digunakan adalah K-Nearest Neighbour dengan nilai k meliputi 1, 3, 5 dan 7. Nilai akurasi tertinggi diperoleh dari ekstraksi ciri zoning 9 zona dan KNearest Neighbour dengan nilai k = 1, yaitu sebesar 79%.

Judul: Pengenalan Aksara Jawa Tulisan Tangan dengan Menggunakan Ekstraksi Fitur Zoning dan Klasifikasi K-Nearest Neighbour
Abstrak: Various studies on traditional script recognition continued to be developed using various methods. One of them is handwritten Javanese script recognition. This research aims to determine the accuracy of the Zoning Feature Extraction and K-Nearest Neighbour Classification method. The data used in this this research are handwritten Javanese script from 20 different peoples. Each of character images will be transformed into 120 x 120 pixels dimension and will undergo the thinning method. The feature extraction method used is the combination of the zoning method ICZ-ZCZ with the number of zones are 4, 6, 8, 9, 10, 12, 15, 16, 18, 20 and 24. K-Nearest Neighbour is used as the classifier with k values are 1, 3, 5 and 7. The highest accuracy was obtained on 12 zones with k = 1 on K-Nearest Neighbour with a value of 71.5%.

Judul: Biology and ecology of the buffalo fly, haematobia exigua de meijere (diptera:muscidae)
Abstrak: The life history of the buffalo fly was observed at room temperature of 27°-29.5°C and at a relative humidity of 48-68 percent. The eggs hatched after 17-22 hours, with an average of 18 hours. First instar larvae measured 1.25 + 0.16 mm long and 0.27 + 0.037 mm wide. reach the second larval stage. It took 6-12 hours to the second instar larvae measured 2.676 +0.187 mm long and 0.353 +0.028 mm wide. The second instar took about 12-24 hours to reach the third larval stage. The third instar measured 6.833 + 0.189 mm long and 0.919 + 0.051 mm wide. It took about 2-3 days for the third instar to become pupae. Duration of the pupal stage was about 5-7 days before the adults emerged. Under laboratory condition, the buffalo fly completed its life cycle in 9.5 to 10.5 days, whereas under field condition it took 9-14 days with an average of 10.5 days. The growth ratio which was based on the measurements of the cephalo-pharyngeal skeleton of each instar was 1.797. The preoviposition period was 8-12 days and mating usually occurred on the 6th or 7th day. The longevity of the male was 29 days, whereas it was 32 days in the female. The range of egg production under laboratory condition was between 20-139 per female fly. The belly and hind legs of the carabao were the most preferred habitat either during cloudy and cool dry or shiny and warm day. When the weather was clear and the carabao was in the shade, the flies tended to be more distributed particularly on the shoulder, dewlap, back and horns. The carabaos had relatively fewer Musca sp. and Stomoxys calcitrans than cattle; never the less carabaos had a higher infestation of buffalo fly than cattle. Oviposition occured either during the day or night but the buffalo flies were more active during the night than in the day time. The effect of various lengths of exposure time of manure in relation to the oviposition was profound. observed, the maximum number of the buffalo flies was occurred when the dung was exposed for 30 minutes. With increasing time of exposure the number and variety of insects also increase. It was evident that Sepsidae and psychodidae were the most dominant insects emerging from the dung. The number of buffalo flies also increased with increasing
