The Evaluation of Nutrition Information System Using Combined Method of Unified Theory of Acceptance and Usage of Technology (UTAUT) and Task Technology Fit (TTF)

Abstract

After more than five years of SIGIZI application implementation, problems arise from hardware, software, brainware to sociotechnical components. Evaluation is needed to find out if the information system remains reasonable to be used, requires improvement or update. This research aims at evaluating the information system SIGIZI based on combined method of UTAUT and TTF. This is a quantitative research with a survey approach, located at all Public Health Centers that implement SIGIZI in the working areas of Banyumas health office. The object is SIGIZI application and the subject is nutrition officers who use SIGIZI. It uses purposive sampling technique. The data are collected using questionnaire. The analysis results indicate that there is relationship of task characteristic and technology characteristic with task-technology fit; there is performance relationship expected from SIGIZI with user acceptance; task-technology fit, ease level of SIGIZI, social influence and condition of SIGIZI facility are not related to user acceptance; there is relationship of task-technology fit with performance expected from SIGIZI; ease level of SIGIZI is not related to performance expected from SIGIZI; there is relationship of technology characteristic and performance expected from SIGIZI.
