Judul: Karakteristik Wirausaha dan Praktek Manajemen Berperspektif Islam serta Hubunganya terhadap Kesuksesan Agribisnis (Kasus Tiga Wirausaha di Kabupaten Bogor dan Sukabumi)
Abstrak: Indonesia is the country with the largest Moslems population in the world with 205 million of Moslems. United Nation said that the country will be able to build its economy if it has the amount of entrepreneurs as much as 2% of the population. But, unfortunately Indonesia still has not reached the number. On the other hand, the agribusiness sector in Indonesia has a great potential and plays an important role in the development of the national economy. However, this sector still has not been much developed. This problem may be caused by many entrepreneurs who do activities in agribusiness is not halal, might include criminality and not blessed by Allah SWT. The objectives of this research are to analyze the entrepreneur’s characteristic and management practice in Islamic perspective also its relationships to success of agribusiness. Phenomenology is a method which tries to capture the Muslim entrepreneur activities and their management practice. There were three entrepreneurs selected for the case studies. The results of the study showed that they have Islamic characteristics, such as siddiq, amanah, fatanah and talbligh. They have implemented Islamic management of agribusiness in their enterprises. They also have got success of agribusiness based on Islamic value and agribusiness development. There are positive relationships between Islamic entrepreneur characteristics and management practices and their success of agribusiness.

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.
