Judul: Evaluasi Sistem Cyber Extension Dalam Perkembangan Informasi Agribisnis
Abstrak: Cyber Extension is one of agricultural innovation communication network development mechanism wich is programmed effectively to gather research, development, and assessment institution with instructors, preceptors, farmers, and other stakeholders wich every each one has different information requirement resulting synergistic and complementary act. The aim of this study is to formulate development system strategy so that it can enhance the existing system. Analysis Method used in this study was Force Field Analysis, the purpose of using this method was to identify driving forces and resisting forces factor to determine the strategy that strengthen the driving forces and weakend the resisting forces. Based on Force Field Analysis, the number of driving factor is determined to be bigger than resisting factor, wich equal to 5,07.

Judul: Efektivitas Cyber Extension Sebagai Media Komunikasi dalam Diseminasi Teknologi Pertanian
Abstrak: Cyber extension is a communication mechanism of agricultural innovation by using new communication media that integrate information and communication technology in agricultural development. The objectives of the research are: (1) to analyze individual characteristics correlation with effectiveness communication media cyber extension; (2) to analyze accessibility correlation with effectiveness communication media cyber extension; and (3) to analyze individual characteristics correlation with accessibility communication media cyber extension. This study was approached by using quantitative method supported by qualitative data. Result of research showed that not all individual characteristic variable correlation with effectiveness. That not all variables correlations accessibility with the effectiveness. Other results showed formal education level correlation with perception of relative advantage level communication media cyber extensions.

Judul: Sintesis dan Pencirian Natrium Titanat (Na2Ti2O4(OH)2) Berbahan Dasar Titanium Dioksida
Abstrak: TiO2 can be utilized as basic material for synthesis of sodium titanate (Na2Ti2O4(OH)2). This research was purposed to synthesize and characterize sodium titanate from TiO2 rutile powder as a basic material. Sodium titanate was synthesized by hydrothermal process at temperature 130 °C by mixing TiO2 rutile powder with 5 M and 10 M NaOH solution, then each was calcinated at temperature 700 °C. The energy dispersive X-ray analysis showed that sodium titanate has been successfully synthesized. This result was also supported by functional group analysis with Fourier transform infrared (FTIR) spectrofotometer showing the existence of Ti-O-Na vibration band at 989.42 cm-1. The formation of sodium titanate was depend on the reaction condition such as temperature, reaction time, and NaOH concentration. Scanning electron microscope image indicated that sodium titanate synthesized at 130 °C in 20 hours reaction time with 10 M NaOH had crystal size of 99.37 nm.
