Judul: Prototipe Program Komputer untuk Menganalisis Sistem Penanganan Pasca Panen Padi
Abstrak: Peralatan dan sistem penanganan pasca panen padi perlu tens dikembangkan dan diperbaiki agar menghasilkan beras dengan mutu yang baik dan jumlah susut yang minimum sehingga usaha-usaha peningkatan produksi padi yang telah dilakukan selama ini menjadi lebih berarti. Secara teknis ada beberapa cara dalam penanganan pasca panen padi yang meliputi pemanenan, perontokan, pembersihan, pengeringan, pengangkutan, penyimpanan, dan penggilingan. Penanganan pasca panen yang dicakup dalam penelitian ini adalah proses pemanenan, perontokan dan pengeringan. Tujuan dari penelitian ini adalah membangun suatu program komputer sebagai alat bantu untuk memilih alternatif cara penanganan pasca panen padi bagi petani. Alternatif cara penanganan dipilih berdasarkan biaya minimum sesuai dengan jenis varietas, jumlah tenaga kerja yang tersedia, luas panen, peralatan yang tersedia, dan waktu panen.

Judul: Distribution and Diversity of Ectoparasite Mites on Geckos in Indonesia
Abstrak: Data on the diversity and dispersal of parasitic mites on house geckos in Indonesia are very scarce. In this work, the distribution and diversity of mites living on three species of house geckos, namely Cosymbotus platyurus, Hemidactylus frenatus, and H. garnotii collected throughout Indonesia, has been elaborated. Geckos and mites were captured and immediately preserved in 70% ethanol. Whole mount of the mites was prepared by clearing in lactophenol followed by mounting on polyvinyl lactophenol solutions. The SEM preparation was conducted to examine the detail morphological characters of the mites. The results showed that among 448 individuals of geckos, 221 geckos were infected by Geckobia mites. Prevalences of C. platyurus, H. frenatus, and H. garnotii infested by mites were 14.8%, 50.69%, and 79.6%, respectively. Three different spesies of Geckobia (G1, G2, and G3) could be differentiated; and based on similarities of their morphological characters to ones described in published literatures, Geckobia G2 is Geckobia glebosum and Geckobia G3 is Geckobia bataviensis while G1 could not be identified to the species level. The highest mean intensity of Geckobia G1 infestation was found on H. garnotii (I=7.0), G. glebosum infestation on H. frenatus (I=3.5), and G. bataviensis infestation on H. garnotii (I=11.8). In general, C. platyurus was infested by the least number of mites. Geckobia G1 were found living on the skin folds on the claws, G. glebosum were found mainly on the body and thigh, and G. bataviensis were found on almost all parts of the host’s body. Geckobia mites are distributed randomly throughout Indonesian Archipelago, following the pattern of distribution of their hosts. So it is concluded that Geckobia G1, G. glebosum, and G. bataviensis are sympatric.
