Judul: Perubahan Sosial Budaya Masyarakat Desa Lingkar Kampus sebagai Dampak Keberadaan Institut Pertanian Bogor
Abstrak: The objectives of this research is to analyze the waves of social change that occurred in Babakan Village since the presence campus of IPB. The result showed that the impact that caused is impact on community life aspects that is structural aspects and cultural aspects of Babakan village community. The changes on structural aspects are the increase of livelihoods diversity, the patterns of stratification changes, the establishment of new social groups, increasingly fading of social interaction and demographic pattern changes. Besides that, the changes on cultural aspects of community are the elements of rural culture changes, the shift of values and norms that exist in the society and also life style change of the rural community. Public attitudes towards the existence of campus of IPB mostly positive value. Public attitudes towards the presence of IPB’s campus has a negative relationship with society characteristics including age, income level and period of resided in Babakan village. Education level have positive relationship with public attitudes. There is also no significant differences in gender characteristic in the formation of attitudes towards the existence campus of IPB.

Judul: Pengaruh Jenis Perubahan Fungsi Rumah Terhadap Taraf Hidup dan Kondisi Sosial Budaya Masyarakat
Abstrak: Perkembangan kampus Institut Pertanian Bogor yang ditandai pertambahan jumlah mahasiswa berdampak pada meningkatnya jumlah permukiman mahasiswa. Hal ini membuat masyarakat sekitar kampus mengubah fungsi rumah dari hunian pribadi menjadi hunian mahasiswa. Tujuan penelitian ini adalah untuk: (1) menganalisis perubahan wilayah yang terjadi akibat berkembangnya permukiman mahasiswa, (2) menganalisis pengaruh jenis perubahan fungsi rumah terhadap perubahan taraf hidup masyarakat; dan (3) menganalisis pengaruh jenis perubahan fungsi rumah terhadap perubahan kondisi sosial-budaya dalam masyarakat. Penelitian ini menggunakan pendekatan kuantitatif dengan metode survei didukung dengan data kualitatif. Lokasi penelitian dilaksanakan di Kelurahan Balumbang Jaya dengan sempel berjumlah 30 masyarakat asli pemilik permukiman mahasiswa. Hasil penelitian menunjukkan bahwa perubahan wilayah di Kelurahan Balumbang Jaya akibat pertumbuhan permukiman mahasiswa membuat semakin sempitnya wilayah persawahan dan tegalan. Jenis perubahan fungsi rumah yang berbeda membuat perbedaan perubahan taraf hidup masyarakat. Selain itu masuknya pendatang membawa perubahan pada kehidupan sosial-budaya dalam hal peningkatan kejadian kriminalitas, persaingan ekonomi, perubahan tradisi serta perubahan gaya hidup.

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.
