Judul: Precision farming of rice cultivation to increase rice productivity
Abstrak: Salah satu usaha untuk meningkatkan produktivitas padi sawah yaitu dengan pengelolaan pertanian secara cermat (precision farming), yang salah satunya yaitu dengan Perlekatan Pengelolaan Tanaman Terpadu (PTT). Penelitian ini bertujuan untuk melihat perbedaan budidaya antara cara petani, PTT pemerinatah, dan PTT cermat; melihat kualitas hasil panen dariketiga pengelolaan petani, PTT pemerintah dan PTT cermat; dan menigkatkan nilai ekonomi / keuntungan usaha tani padi sawah dengan membandingkan efisiensi input dari ketiga budidaya padi sawah.

Judul: Respon Petani terhadap Metode Pengelolaan Tanaman Terpadu (PTT) Padi di Desa Pancawati Caringin Bogor
Abstrak: Riceis a commodity that has been still the staple food of Indonesia so far. Riceis also acommodity that canaffect thesocio-economic conditions, andstate politics. However,related to the currentrice commodities in Indonesia, rice store that has suffered the drawback. Farmer sare required to participatein building the strength of the national food through increased productivity. The claimis often hampered by the powerlessness of farmers in the ability to apply (adoption) the technology. Integrated Crop Management (ICM) is one of the government's efforts to realize the successful achievement of sustainable self-sufficiency through increased productivity. ICM is a participatory holistic approach tailored to site-specific conditions. Therefore, it is not a technology package that must be applied by farmers in all locations. ICM goal is to improve the livelihoods of farmers through the application of appropriate technology to local conditions. The success of a program is influenced by knowledge, skills, and attitudes of actors/doers (farmers) in the field. Research to be conducted is expected to provide feedback information to the farmers' understanding towards this methods asthe efforts to increase rice productivity. This study took place in Pancawati village Caringin bogor. Research subjects in this study are all members of farmer groups in the Pancawati village Caringin bogor. The sampling technique used is using census technique, so the respondents in this study are the entire population of the 125 farmers. Data analysis in this study uses descriptive analysis and SEM (Structural Equation Model) by using PLS program. The analysisconducted inthis study, it can be concluded thatthe responsesof farmers towards this method in improvingrice productivityare good. This can be indicated byrespondents perceptions ofthe knowledge, skillsandgood attitude. Based on the SEM PLS,the knowledge and skills affect productivity but higher skills than the loading factor productivity of knowledge that is more influenced by the skills of farmers but farmers have not been able to make modifications because of conceptual knowledge or lack of knowledge that needed assistance because it involves the application of field and field of technical skills to be successful applying the method of PTT. In the long term knowledge is also needed so that farmers can provide innovation input, modify the method of PTT, PTT method helps application problems. It is shown by the different manner in which the attitude variable does not affect productivity.

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.
