Judul: Peranan Kelompok dalam Mengembangkan Kemandirian Petani dan Ketangguhan Berusahatani
Abstrak: Keterbukaan ekonomi sebagai konsekwensi diterapkannya kesepakatan General Agreement on Tariffs and Trade (GATT), diberlakukannya perdagangan bebas di kawasan Asia Pasifik melalui Asia Pacific Economic Cooperation (APEC) dan adanya kesepakatan negara-negara Asia-Tenggara dalam bentuk Asean Free Trade Area (AFTA), cepat ataupun lambat akan berakibat timbulnya persaingan yang ketat terhadap berbagai komoditas Indonesia di pasar dalam negeri maupun di pasar internasional.

Judul: Impact of the trade liberalization on the Indonesian economy performance: a macro-econometricsapproach
Abstrak: Perkembangan ekonomi dunia dewasa ini telah mengarah pada tatanan hubungan ekonomi secara global, dan lndonesia telah ikut serta dalam sistem tersebut setelah menanda tangani Kesepakatan Umum Tarif dan Perdagangan Multilateral GATT (General Agreement on Tariffs and Trade) melalui WTO yang akan mulai diimplementasi pada tahun 2005. Disamping itu lndonesia ikut pula dalam kesepakatan APEC (Asia Pacific Economic Cooperation) dan AFTA (ASEAN Free Trade Area). Walaupun saat ini Indonesia sedang dilanda krisis ekonomi namun perubahan lingkungan global yang mengarah pada diberlakukannya liberalisasi perdagangan merupakan tantangan eksternal yang makin serius dan pasti. Bagaimana dampak liberalisasi perdagangan khususnya terhadap negara berkembang masih terus diperdebatkan bahkan menimbulkan pendapat aliran optimistik maupun pesimistik. Studi-studi empirik yang telah dilakukan secara umum mendukung konsep bahwa perdagangan bebas akan meningkatkan kesejahteraan masyarakat secara agregat, namun diakui pula bahwa manfaat yang diterima setiap negara tidaklah sama, ada yang lebih diuntungkan atau sebaliknya., The world economy is currently developed toward the global economic relationship system. Indonesia has taken a part in the system as soon as it signed the commitment about General Agreement of Tariffs and Trade (GATT) of WTO. This agreement will be implemented in the year of 2005. Besides, Indonesia has also participated in other agreements like Asia Pasific Economic Cooperation (APEC) and Asean Free Trade Area (AFTA). Though nowadays Indonesia is facing economic and monetary crisis, changes in global environment directed to the implementation of trade liberalization are serious external coercion for Indonesian economy.

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.
