Judul: Perubahan struktur agraria dan implikasinya terhadap gerakan petani Pedesaan (analisa karakter forum Paguyuban Petani jasinga Pasca Ppan)
Abstrak: Masyarakat Desa Curug dan Desa Tegal Wangi mengalami kerugian pasca hilangnya lahan garapan. Kerugian yang dialami berupa pengurangan luas penguasaan lahan dan perubahan tingkat pendapatan. Respon yang dilakukan oleh masyarakat di dua desa tersebut adalah dengan membentuk organisasi Forum Paguyuban Petani Jasinga. Tujuan penelitian ini adalah untuk menganalisis perubahan struktur agraria dan pengaruhnya terhadap karakter gerakan petani. Hasil penelitian menunjukkan tidak terdapat pengaruh antara perubahan status sosial ekonomi terhadap dimensi gerakan petani. Di sisi lain, dimensi gerakan petani memberikan pengaruh terhadap karakter gerakan petani., Curug and Tegal Wangi community are facing the problem related to the land occupation. Two aspects which changed after the decrease of land occupation are the decrease of land tenure and income level. The emerging of Forum Paguyuban Petani Jasinga is a part of their strategy to over come the problem above. This study aims to analyze the influence of agrarian structure change to the character of organization. Result of this study shows there is no influence of change of social economic status to dimensions movement of farmers. On the other side, the dimensions of movement of farmers had influence in the character of movement farmers.

Judul: Pemurnian Rekombinan Eritropoietin Manusia (rhEPO) Menggunakan Kromatografi Afinitas Ni-NTA dan Co-Talon
Abstrak: Suitable and efficient techniques for purification of recombinant human erythropoietin (rhEPO) are required to obtain pure rhEPO which can be continued to preclinical trials step. One of these techniques is immobilized metal affinity chromatography (IMAC), which has advantages such as high selectivity, easy to elute, and simple procedure for column regeneration. At least, there are 2 kinds of commercial IMAC resin using nitriloacetic acid (NTA) matrix as chelating agent, namely nickel-based (Ni-NTA) and cobalt-based IMAC resin (Co-NTA), the latter is well known as Talon. This research studied the influence of metal ions Ni2+ and Co2+ in rhEPO purification. The results indicated that Ni- NTA had higher affinity in binding rhEPO protein compared with Co-Talon. Average total protein by Ni-NTA was 226.72 μg/mL and Co-Talon was 60.52 μg/mL, but the protein purity with Co-Talon was better than Ni-NTA. Base on protein yield that can be separated, Ni-NTA is more suitable to obtain high yield of rhEPO protein.
