Judul: Dampak Perkembangan Toko Modern Terhadap Kinerja Pedagang Produk Pertanian Pada Pasar Tradisional di Kota Bekasi
Abstrak: Modern stores have been present in major cities in Indonesia since last three decades. With the rapid growth of the ritail sector, in 1998, Indonesia made a deal with the IMF that foreign ritelers can freely invest in Indonesia. This has led to the perception that traditional markets are the real victims of the ritail sector competition which leads to reduced consumer due to modern shops can provide advantages that can not be provided by traditional markets such as convenience, product quality and safety. Traditional market traders who sell the majority of agricultural products are in danger because these commodities are also a large part of product line supermarkets and hipermarkets. This study aimed to analyze changes of agricultural products trader performance in traditional markets as the growing number of modern stores in Bekasi and the factors that influence changes of revenue and profits traders of agricultural products. Results of paired t-test showed that there are a change in their respective markets of the variables revenue, profit, operating hours, circulation of goods, number of buyers, the number of customers and the number of employees experiencing. At the revenue variable, real influential factors are a gender dummy, education level, number of kiosk, spacious kiosk, main commodity is rice dummy and main commodity is fresh fruits and vegetables dummy. At the profit variable, real influential factors are a gender dummy, level of education, trading experience, number of kiosk, spacious kiosk and location dummy.

Judul: Dampak Kehadiran Ritel Modern terhadap Profitabilitas Pedagang Pasar Tradisional di Kota Bekasi
Abstrak: The aims of this research are to analyze the impact of modern retail on the profitability level of traditional market traders in Bekasi. The market selection is done by purposive sampling method. Jatiasih Market and Family Mart Market are selected as treatment group and Bantargebang Market is selected as control group. The methods using in this study are t-test, chi-square test, and ordinal logistic regression. Factors influencing changes of profit are the number of buyers, the distance between the traditional market with the modern retail, the main commodity of fresh products and processed products. The closer distance the traditional market to the modern retail, the more chance of traditional market traders to increase their profits.

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.
