Judul: Faktor-faktor yang mempengaruhi efektivitas komunikasi di dalam sekolah lapang padi
Abstrak: A study was carried out to analyze the relationships among influencing factors to communication effectiveness in socialization of technological innovation in conducting the program of Field School of Integrated Crop Management of Rice, in Cikarawang Village, Bogor Barat Sub-district, Bogor City. Data were collected using questionnaire method, and then analyzed using τ - Kendal descriptive method. The results of the study showed that the factor of field guide characteristic had a significant correlation with the communication participation of farmer. The field guide characteristics also had a significant correlation with the technological innovation characteristic (i.e. trialibility and observability). Some elements of farmer characteristics (i.e. age and experience) significantly correlated with the communication participation of farmer. However, all elements of communication channels (type of media and place and time suitability) were not correlated with the communication participation of farmer. This could be due to the absence of other type of media, other than the direct communication (meeting, discussion and field practice). Farmer participation to the main activities of the field school program (PRA, meeting, discussion and field practice) significantly correlated with the knowledge enhancement (cognitive) and with the attitude change tendency (affective) of program-involved farmers. However, the communication participation of farmer was not correlated with the action of program-involved farmers to apply technological innovation of the field school. In other words, although program-involved farmers had obtained enough knowledge and had tendency to choose technological components in the field school program, but in general they had not yet applied optimally the components.

Judul: Posisi Filogenetik Kura-Kura Carettochelys Insculpta  (Reptillia: Testudinata)
Abstrak: Carettochelys insculpta is an endemic freshwater turtle of southern Papua and northern Australia. Phylogenetic position of this turtle is remain unresolved until now. Most of the research conducted show close relationships of C. insculpta and members of Trionychidae family. However, some of the research show distance between C. insculpta and members of Trionychidae family. This research is conducted to analyze phylogenetic relationship between C. insculpta and other members of Testudinata using 12S rRNA, 16S rRNA, and both gene as markers. DNA samples were obtained from three different organisms of C. insculpta. Two species used as outgroups were Alligator mississippiensis and Iguana iguana. Phylogenetic analysis was carried out using Neighbor-Joining method with Felsenstein 1981 (F81) modeltest. A polytomy tree of Testudinata was produced by using 12S rRNA gene. However, analysis using 16S rRNA and both genes as markers confirmed that C. insculpta was located between the Chelonidae and the Trionychidae family.
