Judul: Faktor yang Mempengaruhi Penerapan Usahatani Padi Organik di Kabupaten Tasikmalaya
Abstrak: The economics and enviromental justification for organic farming could be considered strong enough to promote its adoption. Specially in the developing countries. Due the problems that are facing in conventional farmers,and reported benefits and opportunities derived from organic farming, questions may be asked about why organic rice farming is not adopted by most of the farmers. This research aims to analyze organic rice farming profit compare to conventional rice farming, and to analyze determinant factor in adopting of organic farming in Tasikmalaya. By using R:C ratio it can be proved that organic rice farming is more beneficial than conventional rice farming. Beside that, the result from using logit regression showed that the important factors in adopting organic farming is the training and farming profit.

Judul: Pendapatan Usahatani dan Faktor yang Mempengaruhi Pemilihan Usahatani Padi Organik di Desa Sundawenang Kabupaten Tasimalaya.
Abstrak: Desa Sundawenang merupakan wilayah pengembangan padi organik di Kabupaten Tasikmalaya. Jumlah petani padi organik cenderung menurun. Adapun tujuan dari penelitian ini ialah membandingkan pendapatan usahatani dan mengidentifikasi faktor-faktor yang mempengaruhi pemilihan usahatani padi organik di Desa Subdawenang. Analisis pendapatan dilakukan dengan melihat selisih penerimaan dan biaya. Kemudian Perbandingan pendapatan dilakukan dengan menggunakan alat uji-t. Analisis faktor dilakukan dengan menggunakan alat analisis regresi logistik. Hasil perbandingan pendapatan menunjukan bahwa rata-rata pendapatan usahatani padi organik tidak berbeda secara stastistik. Ratarata pendapatan padi organik yang diperoleh petani ialah Rp11 379 544.12/ha dan rata-rata pendapatan yang diperoleh pada usahatani padi non organik ialah Rp10 920 168.44/ha. Adapun faktor-faktor yang mempengaruhi pemilihan usahatani padi organik di Desa Sundawenang ialah produktivitas, pendapatan, umur serta pengalaman usahatani.

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.
