Judul: Search engine pada dokumen online shop menggunakan metode berbasis konsep
Abstrak: Ecommerce atau online shop telah banyak menawarkan kemudahan, salah satunya berupa fitur mesin pencari. Mesin pencari yang digunakan online shop pada saat ini masih menggunakan sistem pencarian berbasis keyword dan menimbulkan beberapa masalah seperti efek kata polisemi dan homonim. Hal ini menyebabkan kinerja mesin pencari menjadi tidak optimal. Oleh karena itu, diperlukan model mesin pencari berbasis konsep untuk mengatasi masalah tersebut. Teknik temu kembali berbasis konsep mengurutkan dokumen berdasarkan kombinasi kemiripan kata dan konsep, sehingga mesin pencari dapat melakukan interpretasi lebih jauh terhadap kueri pengguna. Struktur konsep yang baik diperlukan untuk meningkatkan kinerja pencarian berbasis konsep, terutama situs online shop yang memiliki banyak data produk. Cara terbaik untuk mendapatkan struktur konsep terbaik adalah dengan melalukan percobaan.

Judul: Pengembangan mesin pencari pada online shop menggunakan pemodelan dokumen ontologi produk
Abstrak: Mesin pencari pada online shop memegang peranan penting sebagai fasilitas untuk menemukan produk yang dibutuhkan oleh konsumen. Relevansi antara query masukan dengan hasil yang ditampilkan oleh sistem terkadang menjadi permasalahan disaat mesin pencari tidak dapat merepresentasikan pengetahuan dari data pada dokumen. Penelitian ini mengajukan sebuah model ontologi untuk mesin pencari. Fokus dari penelitian ini adalah melakukan pemodelan ontologi pada data produk milik e-commerce dan menerapkannya untuk modifikasi pada query. Penelitian ini mengukur performa mesin pencari dengan membandingkan pencarian menggunakan model ontologi dan model relasional database. Pada penelitian ini diujikan 20 query menggunakan Solr pada 76,518 data produk milik e-comerce Blibli.com. Hasil evaluasi menunjukan bahwa mesin pencari menggunakan model ontologi lebih baik dibandingkan dengan tanpa ontologi. MAP (mean average precision) search engine menggunakan model ontologi sebesar 0.94.

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
