Judul: Solusi Persamaan Schrodinger Nonlinier Kuintik dengan Koefisien Bergantung Variabel Berdasarkan Transformasi Similaritas.
Abstrak: Persamaan Schrodinger Nonlinier (NLS) merupakan salah satu persamaan yang paling banyak muncul dalam cabang-cabang fisika, diantaranya seperti Optik Nonlinier, Fisika Nuklir dan Bose-Einstein Kondensat (BECs). Maka dari itu, pengembangan persamaan ini akan sangat berguna untuk menambah pembendaharaan pengetahuan. Penelitian ini bertujuan untuk menemukan solusi persamaan NLS kuintik dengan menggunakan metode transformasi similaritas. Solusi yang didapat akan menambah pembendaharaan pengetahuan khususnya untuk menejemen soliton.

Judul: Interaksi 2-Soliton Pada Sistem Komunikasi Optik Nonlinier Dalam Orde Durasi Pikodetik dan Femtodetik
Abstrak: Tujuan Penelitian ini, lllltuk mengetahui interaksi 2-soliton pada sistem komunikasi optik nonlinier dalam orde durasi pikodetik dan femtodetik. Dimana dengan diketahni adanya interaksi 2-soliton dapat dikatakan bahwa persamaan tersebut memiliki solusi soliton (bukan hanya sekedar solusi gelombang solitair) dan kemllllgkinan memiliki solusi N-soliton. Tinjauan analitis dengan Metode Hirota digunakan lllltuk mengetahui pola interaksi 2- soliton, pada sistem komunikasi optik nonlinier dalarn orde durasi pikodetik dengan cara memecahkan persamaan Nonlinier Schrodinger (NLS), untuk orde dnrasi femtodetik dengan cara memecahkan persamaan NLS ditarnbah suku Self Steepening (SS) dan Stimulated Raman Scattering (SRS), sedangkan Third Order Dispersion (IVD) akan diabaikan.

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
