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: Income Analysis and Factors Affecting Willingnes to Adopt for SRI Organic Method in Rice Farming (Case Study: Bumi Harapan Village, Wita Ponda Subdistrict, Morowali District, Provinsi Sulawesi Tengah)
Abstrak: Analisis Pendapatan dan Faktor-Faktor yang Memengaruhi Willingnes to Adopt Metode SRI Organik Pada Usahatani Padi (Studi Kasus : Desa Bumi Harapan, Kecamatan Wita Ponda, Kabupaten Morowali, Provinsi Sulawesi Tengah). Dibimbing oleh HASTUTI dan DEA AMANDA. Indonesia mencapai swasembada beras nasional tahun 1984 dengan sistem pertanian konvensional, prestasi tersebut tidak berkelanjutan karena dihadapkan berbagai masalah. Menyikapi permasalahan tersebut, inovasi pertanian padi organik dapat diterapkan. Pertanian Organik berbasis kearifan lokal diperkenalkan untuk pengembangan pertanian organik adalah System of Rice Intensification (SRI) Organik. Tujuan penelitian (1) menganalisis persepsi petani terhadap penggunaan metode SRI Organik, (2) menganalisis perbandingan pendapatan padi Organik dan padi konvensional, (3) menganalisis faktor yang memengaruhi kesediaan adopsi metode SRI Organik. Penelitian ini menggunakan analisis skala Likert untuk mengetahui persepsi petani, analisis pendapatan untuk mengetahui perbandingan pendapatan, dan analisis regresi logistik untuk mengetahui faktor yang memengaruhi kesediaan adopsi. Hasil persepsi penggunaan metode SRI Organik pada petani yang mengadopsi metode SRI Organik yang tertinggi yaitu produksi padi SRI Organik yang lebih tinggi dan sehat, persepsi terendah teknis budidaya SRI organik yang rumit. Persepsi terhadap penggunaan metode SRI Organik pada petani yang belum mengadopsi metode SRI Organik tertinggi yaitu SRI Organik menggunakan pupuk dan pestisida ramah lingkungan, persepsi terendah yaitu ketersediaan tenaga kerja pertanian produktif dan terampil terbatas. Analisis pendapatan menunjukan R/C ratio lebih dari satu artinya usahatani menguntungkan. Faktor yang signifikan memengaruhi petani mengadopsi padi metode SRI Organik yaitu pengalaman, pernah mendapat pelatihan dan status kepemilikan lahan.

(Case Study: Bumi Harapan Village, Wita Ponda Subdistrict, Morowali District, Provinsi Sulawesi Tengah). Supervized by HASTUTI and DEA AMANDA. Indonesia achieving national rice self-sufficiency in 1984 with a conventional farming system, this achievement is not sustainable because it is faced with various problems. In response to these problems, organic rice farming innovations can be applied. Organic agriculture based on local wisdom introduced for the development of organic agriculture is the Organic System of Rice Intensification (SRI). The objectives of the study (1) were to analyze farmers' perceptions of the use of the Organic SRI method, (2) to analyze the income comparison between Organic and conventional rice, (3) to analyze the factors that influenced the willingness to adopt the Organic SRI method. This study uses a Likert scale analysis to determine farmer perceptions, income analysis to determine income comparisons, and logistic regression analysis to determine factors that influence adoption willingness. The results of the perception of the use of the Organic SRI method on farmers who adopt the Organic SRI method are the highest, namely the production of organic SRI rice which is higher and healthier, the lowest perception of complicated organic SRI cultivation techniques. The highest perception of the use of the Organic SRI method in farmers who have not adopted the Organic SRI method is Organic SRI using environmentally friendly fertilizers and pesticides, the lowest perception is that the availability of productive and skilled agricultural labor is limited. Income analysis shows that the R/C ratio is more than one, meaning that

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.
