Penelitian didesain sebagai penelitian survei yang bersifat deskriptif korelasional yang dilaksanakan di Desa Tugu Selatan, Kecamatan Cisarua, Kabupaten Bogor. Menggunakan teknik random sampling. diperoleh 50 petani. Analisis data untuk mengetahui hubungan antar peubah menggunakan rank spearman (rs). Hasil penelitian menunjukkan bahwa Petani dalam mengakses sumber informasi rata-rata 2 kali dalam satu bulan. Petani dalam mengakses informasi yang tertinggi kelompok tani dan penyuluh. Petani banyak memperoleh ragam materi dari penyuluh dan kelompok tani. Pemanfaatan informasi yang terbanyak adalah motivasi dan pemecahan masalah yang bersumber dari kelompok tani dan penyuluh. Umur berhubungan nyata dengan frekuensi mengakses informasi dari penyuluh, pengalaman berhubungan nyata dengan frekuensi dan durasi mengakses informasi yang bersumber dari penyuluh, pengalaman berhubungan sangat nyata dengan peubah mengakses informasi yang bersumber dari kelompok tani, pengalaman berhubungan nyata dengan durasi mengakses informasi yang bersumber dari kelompok tani. Frekuensi, durasi dan jenis ragam materi yang bersumber dari penyuluh dan kelompok tani berhubungan sangat nyata dengan pemanfaatan informasi oleh petani. frekuensi mengakses informasi dari surat kabar berhubungan nyata dengan pencerahan. Frekuensi mengakses informasi dari majalah dan brosur berhubungan nyata dengan pencerahan, pemecahan masalah, konfirmasi, proyektif dan motivasi. Durasi mengakses informasi yang bersumber dari surat kabar berhubungan positif dengan pencerahan., The concept of agricultural development towards modern agriculture keeps growing along with the development of science and technology in the field of farming technology and management, supported by the fast development of communication technology. In the current agricultural community, information becomes a significant part since it plays a vital role in supporting farmers to improve the effectiveness and efficiency of farming processes, decision making, and innovation to flourish. The aims of this study were (1) to describe vegetable farmers exposure to information sources, (2) to analyze the relationship between the characteristics of farmers and exposure to information sources, and (3) to analyze the relationship between exposure to information sources and the utilization of information sources.

Judul: Electrophoretic Coating of Apatite Compouds on Stainless Steel 316L.
Abstrak: Stainless steel (SS) 316L is a metal which is used to bone plate. However, this metal still has low biocompatibility in a human body. The metal is coated by HAp in order to increase its biocompatibility. HAp on SS 316L is coated by electrophoretic deposition (EPD) method. We used two variables in EPD process, such as voltage and coating time to obtain the best coating. The XRD difractogram showed that SS 316L has been coated by HAp. Physical observation used by microscope optics showed that the best coating is achieved on 120V during 2 minutes.
