Judul: Analisis dayasaing dan dampak kebijakan pemerintah terhadap komoditas kakao (Kasus : PTPN VIII Kebun Cikumpay Afdeling Rajamandala Bandung)
Abstrak: This study identifies competitiveness of cacao. The objectives of this study are to analyze competitiveness of cacao in PTPN VIII Cikumpay Rajamandala, to analyze government policy effect in competitiveness of cacao in PTPN VIII Cikumpay Rajamandala, and to analyze the change effect of productivity, cacao price, and exchange rate of rupiah to competitiveness of cacao in PTPN VIII Cikumpay Rajamandala. This research uses Policy Analysis Matrix (PAM) to analyze the data. The results suggest that cacao from PTPN VIII Rajamandala have competitiveness. Value of PCR (0.92) and DRC (0.95) reveal that cacao have comparative and competitive advantages. The value of NPCO indicates that government policy (basic price for PTPN) is support competitiveness of cacao, but the value of NPCI shows that governnment policy (removal of fertilizer subsidies for PTPN) is not support competitiveness of cacao. Sensitivity analysis indicates that productivity, price of cacao and exchange rate of rupiah influence the competitiveness of cacao in PTPN VIII Cikumpay Rajamandala West Java. Key word: Cacao, Competitiveness, Policy Analysis Matrix, government policy effect, sensitivity analysis.

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.
