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: Faktor-faktor yang Berhubungan dengan Pemanfaatan Cyber Extension
Abstrak: Cyber extension generally aims to develop agricultural information system based on integrated web; efficient; and beneficial to the agricultural extension, the extension institutional, and also agribusiness actors or society in general. The aims of this study were to determine the relationships of agricultural extension counselor characteristic, the counselor perceptions of cyber extension characteristics, and associated external factors of the intensity use of cyber extension and level of perceived usefulness. This study used survey method with a a sample of 36 agricultural extension counselors that used cyber extension. Results of statistical analysis of Spearman Rank test and Chi-Square showed that only age, the modern mass media possession, the experience of using the internet, and the level of motivation which had associated with the intensity use of cyber extension and level of perceived usefulness. While for the perceptions of the characteristics of cyber extension showed that only one perception variable had related with the extension and intensity use of cyber extension and level of perceived, which is perceived level of probability attempt of cyber extension. The result showed that no relation of external factors with intensity of use of cyber extension and level of perceived usefulness.

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.
