Judul: Modernitas Sikap Kewirausahaan Pengurus Koperasi (Studi Kasus pada Koperasi Karyawan di Kecamatan Cibinong, Kabupaten Bogor, Jawa Barat)
Abstrak: Cooperatives as a business entity, that given the image of a pillar of national economy, are challenged to be managed professionally. In general, the main problem still facing the cooperatives is the low professionalism of the managers. This study aims to explain the modernity of entrepreneurial attitude of cooperative managers, and to explain the relationship between modernity of entrepreneurial attitude of cooperative managers with the cooperative's success. This research was carried out in Cibinong district, Bogor regency, West Java by using the census method that takes the entire population with the sampling frame is cooperation employees. Respondents were selected randomly as many as 3 people from each cooperative employee. Data of characteristics respondents and modernity of entrepreneurial attitude presented in the form of frequency tabulation. Meanwhile, to know the relationship between modernity of entrepreneurial attitude of cooperative managers with the cooperative's success using Spearman Rank (rs or ρ ) Correlation Test. The modernity of entrepreneurial attitude is measured consists of 8 variables: (1) precede of priorities; (2) taking risks; (3) innovativeness; (4) hard work; (5) appreciation for the time; (6) achievement motivation; (7) selfconfidence; and (8) individual responsibility. Whereas, the variable of cooperative's success is measured over the two indicators, there are the number of cooperative's members and the rest of the business (“sisa hasil usaha/SHU”). This study found that respondents generally have a modern view of the eight themes of entrepreneurial attitude. When observed on each theme being, there is a tendency of respondents who have no modern attitudes, especially in the second theme ( "risk taking"). While the theme of most modern attitude of the respondents owned is on the first theme ( " achievement motivation "). Through using Spearman Rank Correlation Test is known that the variable of modernity of entrepreneurial attitude has no correlation with the cooperative's success. Compute rs values obtained are smaller than rs table, which means modernity of entrepreneurial attitude of cooperative managers is not related to the success of cooperative employees. With these test results indicate that the view of modernity can be owned by each board committee is no exception in the cooperative does not succeed. Thus, the cooperative's success is measured by the number of cooperative's members and the rest of the business (“sisa hasil usaha/SHU”), not entirely influenced by entrepreneurial attitude of managers. However, more determined by external factors such as mutation of employees, employee rotation, the period of retirement, the layoffs and other things that cause the cooperative does not succeed. In turn, these conditions would cause the cooperatives decreasing in the rest of the business (“sisa hasil usaha/SHU”). Keyword : Entrepreneurship, cooperative, and cooperative's success

Judul: Analisis Faktor-Faktor yang Berkorelasi dengan Sikap Kewirausahaan Peternak Kelinci (Kasus: Koperasi Peternak Kelinci Kabupaten Bogor, Jawa Barat)
Abstrak: Tujuan penelitian ini adalah (1) Menganalisis tingkat sikap kewirausahaan peternak kelinci Kabupaten Bogor, Jawa Barat. (2) Menganalisis faktor-faktor yang berkorelasi dengan sikap kewirausahaan peternak kelinci Kabupaten Bogor, Jawa Barat. Penelitian dilaksanakan di Kabupaten Bogor. Waktu penelitian dilaksanakan selama sebulan yaitu bulan Mei hingga bulan Juni 2012. Responden penelitian adalah para anggota koperasi yang aktif yaitu sebanyak 50 orang peternak. Penelitian ini menggunakan analisis korelasi Rank Spearman. Data yang digunkan pada penelitian ini adalah data primer dan data sekunder. Instrumen yang digunakan dalam penelitian ini adalah kuesioner, penyimpan data elektronik, dan alat pencatat. Untuk memastikan bahwa kuesioner yang digunakan dapat dipercaya dan valid, maka dilakukan uji reliabilitas dan uji validitas. Hasil uji reliabilitas menunjukkan Cronbach’s Alpha lebih besar dari 0,600, sedangkan untuk hasil uji validitas menunjukkan Cronbach’s Alpha lebih besar dari 0,500. Hal ini berarti semua pertanyaan yang diujikan sudah reliabel dan valid. Faktor-faktor yang diduga dapat mempengaruhi sikap kewirausahaan adalah faktor internal dan faktor eksternal. Faktor internal terdiri dari umur, pendidikan, minat berwirausaha, dan pengalaman beternak. Faktor eksternal terdiri dari ketersediaan input, pelatihan, dan ketersediaan media informasi. Sikap kewirausahaan diantaranya pemanfaatan peluang, berorientasi pada hasil, kemampuan berinteraksi, bekerja keras, pengambilan risiko, percaya diri, pengendalian diri, keinovatifan, dan kemandirian. Hasil Penelitian ini adalah secara umum responden anggota Koperasi Peternak Kelinci (KOPNAKCI) yang memiliki usaha ternak kelinci memiliki tingkat sikap kewirausahaan dalam taraf sedang. Hal ini berarti bahwa peternak kelinci anggota KOPNAKCI bersikap terhadap sembilan aspek pemanfaatn peluang, orientasi hasil, kemampuan berinteraksi, bekerja keras, pengambilan risiko, percaya diri, pengendalian diri, keinovatifan, dan kemandirian tergolong kategori sedang. Berdasarkan uji korelasi rank Spearman diketahui bahwa peubah-peubah pada faktor internal saling bebas (tidak ada hubungan) dengan sikap kewirausahaan secara keseluruhan dalam taraf kepercayaan 10 persen. Hal ini berarti bahwa semakin tinggi umur, motivasi, pendidikan, dan pengalaman beternak maka tidak akan selalu diikuti dengan semakin tinggi sikap kewirausahaan. Faktor eksternal memiliki hubungan dengan sikap kewirausahaan secara keseluruhan dalam taraf kepercayaan 10 persen, yaitu pada peubah pelatihan dan ketersediaan media informasi. Hal ini berarti bahwa semakin tinggi pelatihan dan ketersediaan media informasi, maka akan selalu diikuti dengan semakin tinggi sikap kewirausahaan.

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.
