Judul: Metode Alternatif dalam Pencarian Peringkat E-commerce di Indonesia Berdasarkan Penilaian Pelanggan.
Abstrak: Keberadaan internet memunculkan sistem perdagangan secara online menggunakan aplikasi. Maraknya sistem perdagangan secara online memicu muculnya berbagai e-commerce di Indonesia yang menyediakan berbagai macam kebutuhan pelanggan. Hal ini juga menimbulkan permasalahan bagi pelanggan yaitu kesulitan dalam memilih e-commerce yang berkualitas. Upaya yang dilakukan untuk mengatasi masalah ini adalah membuat peringkat e-commerce di Indonesia berdasarkan dari penilaian pelanggan. Metode yang umum digunakan untuk pemeringkatan adalah metode Analytical Hierarchy Process (AHP) tetapi dalam praktiknya terdapat beberapa peubah yang tidak terdapat di e-commerce sehingga metode AHP tidak bisa digunakan. Metode alternatif yang dipilih adalah metode optimasi Ant Colony Optimation (ACO). Pengujian kelayakan metode ACO dalam pencarian peringkat untuk data e-commerce perlu dilakukan karena tidak semua peubah terdapat di e-commerce. Simulasi untuk pencarian peringkat dilakukan menggunakan 2 skenario data bangkitan dengan metode AHP dan ACO. Hasil simulasi didapatkan kesimpulkan metode ACO layak digunakan untuk pemeringkatan yang terdapat data kosong sampai 15%, selanjutnya dilakukan penerapan metode ACO untuk data e-commerce di Indonesia dengan kondisi data kosong 6.25%. Hasil tabu terbaik berdasarkan nilai peluang tertinggi, feromon terendah, dan koefisien korelasi tertinggi yaitu pada tabu ke-2, dengan tiga peringkat teratas yaitu JD, SP, dan TP.

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
