Judul: Analisis perdagangan benang sutera alam Indonesia dan biaya sumberdaya domestikpengusahaan kokon sebagai bahan baku benang sutera alam
Abstrak: Persuteraan Alam merupakan jegiatan agroindustri yang memiliki rangkaian Kegiatan yang panjang dengan produk yang beragam. Permintaan benang sutera Homestik hingga saat ini belum dapat dipenuhi oleh produksinya sehingga untuk memenuhu kebutuhan industri sandang, Indonesia harus mengimpor benang sutera dari luar. Indonesia sendiri memiliki potensi yang cukup baik untuk mengembangkan persuteraan alamnya dalam rangka memenuhi permintaan pasar domestik komoditas Sutera dan megurangi impor serta memanfaatkan peluang pasar dunia. Pencapaian ke arah tujuan tersebut harus memperhatikan kondisi perdagangan komoditas sutera dalam negeri dan kelayakan untuk pengembangan persuteraan alam dengan mamanfaatkan sumberdaya domestik yang dimiliki. Tujuan dari penelitian ini adalah (1) Menganalisis faktor-faktor yang mempengaruhi permintaan dan penawaran kokon dan respon luas penanaman murbei sebagai komoditas hulu sutera alam, (2) Menganalisis faktor-faktor yang mempengaruhi permintaan, penawaran, impor dan harga domestik benang sutera alam, dan (3) Menganalisis keunggulan komparatif dan kompetitif pengusahaan kokon sebagai bahan baku benang sutera alam sebagai acuan dalam pengembangan persuteraan alam. Penelitian ini dilakukan pada lingkup nasional dengan data sekunder dengan rentang waktu 20 tahun untuk analisis perdagangan benang sutera alam. Sedangkan untuk analisis keunggulan komparatif dan kompetitif pengusahaan kokon mengambil kasus pada enam desa di Kabupaten Sukabumi dengan menggunakan data sekunder…dst

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
