Judul: Pola komunikasi pada pengembangan kapasitas kewirausahaan petani sayuran (kasus pendampingan misi teknik taiwan di Kabupaten Boyolali dan Bogor)
Abstrak: The objectives of this research were: (1) to analyze effect of characteristic factors such as social dynamic, physical environment, farmers’ characteristics and socio-economic environment of entrepreneurship communication patterns; (2) to ensure important factors that will strongly influence the increasing of entrepreneurship capacity; (3) to formulate effective communication pattern for entrepreneurship capacity development efforts of vegetable farmer in the Taiwan’s technical mission in two districts in Indonesia. This research resulted several outputs, namely: (1) communication pattern of farmers’ entrepreneurship in Taiwan’s technical mission was categorized good enough and significantly influenced by group dimensions i.e membership and group climate on social dynamics; (2) the development of farmers’ entrepreneurship capacity in Taiwan’s technical mission was categorized good and it was directly influenced by education level characteristics and farmers’ business experiences, it was also influenced by physical environment on dimensions of communication infrastructure and technology characteristics, it was significantly influenced by socio-economic environment on dimension of support social system and mass media information, and also significantly affected by family support dimension, institutional support and local knowledge functioning of socio-economic environment and significantly influenced by dialogic dimension on farmers’ communication entrepreneurship pattern; (3) effective communication patterns regarding development of entrepreneurship capacity of farmers was dialogic communication patterns, and communication pattern itself were strengthened by these factors: social dynamic on group climate and group dimension of membership dimensions. (4) some of the forms of technical skill, social skill, and managerial skill that potentially can improve and compete towards farmers were entrepreneur technical skill, social skill, and managerial skill. By improving their technical skill, social skill, and managerial skill, it was expected farmers were able to improve their productivity, income, autonomy which at the end can develop farmers’ welfare in Indonesia.

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: Separation of Neodymium from U3Si2/Al Fuel Plate for Burn-Up Determination
Abstrak: Neodymium is a common fission product produced in nuclear fission reactions. Neodymium in this study was chosen as a burn-up indicator for U3Si2/Al fuel element plates because the neodymium isotope is a stable fission product with a fairly high yield. Some procedures were carried out to separate neodymium, starting with the separation of cesium isotopes (137Cs, 134Cs) through the precipitation method, then separation of uranium isotopes (235U, 238U) and plutonium isotopes (239Pu, 238Pu) with Dowex 1x8 ion exchange resin, and separation of neodymium (Nd), samarium (Sm), as well as cerium (Ce) with Dowex 1x4 ion exchange resin. The Cs recovery reached 99.95%. The U and Pu isotopes resulting from the separation are subjected to an electrodeposition process and the weight of each isotope can be measured with an alpha spectrometer. The separation results of Nd from Sm and Ce have been proven using an XRF spectrometer. The neodymium isotopes separation was corrected using the standard addition method, and an average total Nd content of 2.4 ppm was obtained in the PEB U3Si2/Al bottom solution. It is hoped that this separation method can be applied in determining burn-up of nuclear fuel.
