Judul: Hubungan Karakteristik Inovasi Budidaya Padi Metode SRI (System Rice of Intensification) dengan Pengambilan Keputusan Adopsi oleh Petani
Abstrak: SRI (System Rice of Intensification) adalah suatu metode budidaya padi yang sedang digalakkan untuk meningkatkan produktivitas pertanian, namun masih menghadapi kendala dalam penerimaannya oleh masyarakat. Salah satu faktor yang berhubungan dengan pengambilan keputusan adopsi adalah karakteristik inovasi. Tujuan dari penelitian ini adalah menganalisis hubungan karakteristik inovasi dengan pengambilan keputusan adopsi dan menganalisis hubungan faktor internal dan eksternal dengan pengambilan keputusan adopsi. Metode penelitian menggunakan metode survey yang didukung dengan informasi kualitatif. Hasil dari penelitian ini adalah keuntungan relatif inovasi mendukung tahap konfirmasi; faktor kesesuaian inovasi mendukung tahap pengenalan; faktor kemudahan dicoba sangat mendukung tahap persuasi; faktor umur petani mendukung tahap pengenalan; dan dukungan ekonomi mendukung tahap pengenalan dan tahap konfirmasi.

Judul: Tingkat Persepsi dan Adopsi Petani Padi terhadap Penerapan System of Rice Intensification (SRI) di Desa Simarasok, Sumatera Barat
Abstrak: System of Rice Intensification or SRI is one of the methods in rice cultivation techniques. SRI is a rice cultivation practice that gives more attention to the conditions of better plant growth, especially in the root zone compared to traditional cultivation techniques. The aims of this study are to identify the perception and adoption level of farmers’ adoption in implementing SRI method and to analyze the factors that influence the adoption of SRI method. A questionnaire survey was conducted at Simarasok Village, Baso Sub-district, Agam District, West Sumatera to 35 farmers by purposive sampling. The data were processed by using logistic regression. The results showed that 57.1 percent of respondents had a good perception of the adoption of SRI while the remaining 42.9 percent had a bad perception. Meanwhile, the adoption rate of farmers was 51.4 percent of respondents have implemented the method in accordance with the guidelines of SRI and the remaining 48.6 percent have not yet. Logistic regression analysis showed that there were three variables that significantly affect the rate of SRI adoption which are farming experience, age and level of perception.

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.
