Kualitas dan Efektivitas Sistem Informasi Berbasis Komputer

Information system refers to a highly valuable resource for an organization because the organization really needs this kind of resources to ascertain the perfection, effectiveness and efficiency.  To avoid from rejection to the developed information system needs to improve information system quality because it affects the user satisfaction rate for the development system. Research aims at observing whether three dimensions of quality, such as information quality, system quality, and service quality affect the effectiveness of information system.  This effectiveness relies on the user satisfaction rate.  Pursuing this research objective, the used analysis to examine Hypothesis  1  (H I),  Hypothesis  2  (H2),  and  Hypothesis  3  (H3) constitutes  multiple-regression statistic  test. Research  sample  includes  the  employee  or  the  user o f information  system  in  9 types  o f company  or  institution  located  at  East  Java,  with  total  reaching  126 participants. Results of classic assumption fesf indicate that multicolinearity, autocorrelation, and heteroscedasticity don't develop in the regression model.  F test shows that Information Quality, System Quality, and Service Quality simultaneously affect the Computer based Information System Effectiveness. Results of research determine that system quality and service quality have significant effect on system effectiveness, while information quality doesn’t significantly affect system effectiveness.  This becomes evident due to lack of employee's knowledge about the system and shorter work incumbent among the employee. Key words: Information Quality.  System Quality, Service Quality,  System  Effectiveness,  Computer-based Information System
