Judul: Sistem Identifikasi Penyakit Akasia Menggunakan Ontologi dengan SQWRL dan Temu Kembali Informasi dengan DFRSimilarity
Abstrak: Akasia merupakan bahan baku industri pulp and paper. Permasalahan pada tanaman akasia adalah adanya ancaman hama dan penyakit yang menyerang tanaman tersebut. Saat ini identifikasi masih dilakukan secara manual karena tidak adanya ahli untuk penyakit akasia. Identifikasi menggunakan sistem komputer dapat memberikan akurasi dan konsistensi yang cukup tinggi. Tujuan dari penelitian ini adalah membuat sistem identifikasi penyakit akasia menggunakan ontologi dengan SQWRL dan temu kembali informasi dengan DFRSimilarity, sehingga dapat membantu mendiagnosa penyakit akasia. Evaluasi OntoQA menunjukkan bahwa struktur ontologi yang dibuat membawa informasi yang sedikit, tetapi pengetahuannya cukup mendalam, dengan rata-rata jumlah atribut pada setiap class adalah 1. Berdasarkan hasil evaluasi, kinerja DFRSimilarity sebesar 0.8861 sedangkan kinerja TFIDFSimilarity sebesar 0.92445.

Judul: Temu Kembali Penyakit Akasia menggunakan Ukuran Kemiripan Cosine Similarity.
Abstrak: Akasia merupakan salah satu tanaman kayu untuk bahan baku industri hasil hutan. Namun, meningkatnya jumlah penyakit menjadi suatu masalah yang dapat menurunkan produktivitas akasia. Saat ini, informasi penyakit akasia sukar diperoleh karena masih tersedia dalam dokumen tertulis. Oleh karena itu, dibutuhkan suatu temu kembali informasi penyakit akasia dengan menggunakan ukuran kemiripan cosine similarity. Temu kembali Informasi penyakit ini mengembalikan informasi yang relevan dari query yang diberikan. Hasil ini diperoleh dari hasil pencarian keterhubungan kemiripan dokumen secara keseluruhan terhadap query. Pada penelitian ini menggunakan 14 dokumen penyakit dan 20 query yang dievaluasi dengan normalized discounted commulative gain (NDCG). Percobaan ini menghasilkan nilai rata-rata NDCG tertinggi sebesar 93.1%.

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
