Judul: Participatory Communication and Collective Action to Farmers Groups in the Bogor Regency (Case: Farmer Groups in the Ciawi Region, Bogor Regency)
Abstrak: Komunikasi partisipatif merupakan kunci dalam sebuah proses komunikasi yang melibatkan masyarakat khususnya di bidang pertanian dalam upaya penyampaian aspirasi dan pendapat. Pertanian yang berdaulat menjadi tujuan utama dalam peningkatan petani lokal dalam pemanfaatan lahan pertanian melalui aksi kolektif. Tujuan dari penelitian ini adalah mengidentifikasi komunikasi partisipatif pada kelompok tani dan hubungannya dengan karakteristik kelompok tani, mengidentifikasi aksi kolektif pada kelompok tani dan hubungannya dengan komunikasi partisipatif. Metode penelitian yang digunakan adalah metode kuantitatif melalui metode survey dan didukung oleh data kualitatif dengan responden sebanyak 30 orang yang berlokasi di Wilayah Ciawi, Kabupaten Bogor. Hasil penelitian menunjukkan tingkat komunikasi partisipatif dan aksi kolektif pada kelompok tani berada pada tingkat tinggi. Terdapat hubungan yang nyata antara dukungan penyuluh dengan komunikasi partisipatif, namun terdapat hubungan tidak nyata pada indikator lainnya, yaitu usia kelompok, besaran kelompok, rata-rata pendidikan, rata-rata luas kepemilikan lahan, rata-rata status kepemilikan lahan, dan rata-rata status bekerja anggota dengan komunikasi partisipatif. Kemudian terdapat hubungan yang tidak nyata antara indikator aksi kolektif dengan komunikasi partisipatif.

Judul: Efektivitas Komunikasi pada Kegiatan Pendampingan Program “Jati Unggul Nusantara” di Desa Ciaruteun Ilir, Cibungbulang, Kabupaten Bogor
Abstrak: The teak business of Usaha Bagi Hasil Koperasi Perumahan Wanabakti Nusantara (UBH-KPWN) unit conducted by a partnerships with farmers. The effective communication between field guides and farmer is important to improve the productivity. The method used in the study is a survey method supported by quantitative and qualitative data. The results showed the characteristics of farmers dominated adulthood, moderate education level, experience in farming classified as moderate, low income, limited arable land, and the farmers' participation in extension activities classified as moderate.Field guides have a close relationship with farmers, very good credibility and attitude,and frequency to visits the farmer group is also quite high,as well as excellent communication field guides. The communication efficacy between farmers and field guides been effective. It is related to the frequency of participation of farmers, proximity, credibility, mastery of the material program, and the appropriateness of extension methods.

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.
