Judul: Sistem penunjang keputusan untuk perencanaan investasi pada proyek industri pulp dan kertas dengan pendekatan portofolio
Abstrak: Penanaman modal merupakan suatu keputusan yang memerlukan pertimbangan mendalam, yang mencakup seluruh informasi yang dibutuhkan, sehingga mampu memberikan gambaran atau proyeksi yang tepat mengenai proyek atau usaha yang dibiayai dan perkembangan dana yang ditanamkan. Salah satu kriteria yang penting adalah resiko yang timbul dari kondisi ketidak pastian di masa datang. Resiko tidak dapat dihindarkan karena setiap keputusan investasi pasti mengandung resiko. Meskipun demikian, penanam modal dapat mengurangi resiko dengan melakukan analisis komparatif sehingga dapat membandingkan resiko atas investasi satu dengan lainnya, yang dapat digunakan sebagai acuan dalam mengambil keputusan. Sebagian besar aktiva keuangan penanam modal merupakan bagian dari portofolio dan bukannya aktiva yang berdiri sendiri. Pada keadaan ini, fokus perhatian dari penanam modal adalah resiko dan tingkat pengembalian satu portofolio sebagai suatu kesatuan. Dengan demikian, penanam modal akan memilih proyek atau aktiva yang menyebabkan suatu diversifikasi yang dapat mengeliminasi resiko portofolio secara keseluruhan. ..

Judul: Sistem Penunjang Keputusan Penanaman Modal Pada Proyek Agroindustri dengan Kriteria Resiko Finansial
Abstrak: Penan,an~an modal pada suatu proyek tidak terlepas dari faktor resiko kegagalan, karena keadaan di masa datang dilingkupi kondisi ketidakpastian. Pada proyek agroindustri kondisi ketidakpastian bersifat spesifik, dipengaruhi oleh sifat produk yang dihasilkan dan cara serta proses produksi yang dapat dipengaruhi oleh alam. Tujuan penelitian ini antara lain untuk membentuk dan mengembangkan sistem penunjang keputusan penanaman modal dalam ruang lingkup probabilistik, menganalisis resiko finansial dan menlpelajari perubahan resiko atas perubahan struktur pembiayaan suatu investasi proyek.

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
