Abstrak: Leadership style and the effectiveness of communication within organization which build in student organization will determine attainment aims organization. BEM KM IPB (Badan Eksekutif Kemahasiswaan Keluarga Mahasiswa Institut Pertanian Bogor) is a formal student organization in level university education. The purpose of this research was to identification the leadership style, to describe the process of communication, to know the effectiveness of communication, and to measure the correlate between leadership style and communication’s process with the effectiveness of communication in BEM KM IPB. The number of respondents in this research were 76 people, with 21 people in levels an ministry and 55 people in levels staff. In general, the leadership style in BEM KM IPB is participative. Although, the members still needs initiative from leader. Communication process in BEM KM IPB enough active based on the direction, media, and the subject of communication. Communication within organization was effective, because the five commponent of effectiveness communication was effective. Leadership style and communication process proven correlate with the effectiveness of communication, and based on media, communication directive, and matter of communication proven corelate with effectiveness of communication.

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.
