The Effect of Perceived Usefulness on Health Information System Application (ASIK) Use Behavior for Immunization Activities in Makassar City

Abstract

Introduction: One of the important areas of research is evaluating the

effectiveness of the Health Information System Application (ASIK) for

immunization activities in Makassar City. This study applied the Technology

Acceptance Model (TAM) to assess the level of acceptance of the ASIK

application in immunization services. The objective of this study was to analyze

the effect of perceived usefulness on use behavior, or actual usage, of the ASIK

application in immunization activities in Makassar City. A quantitative

analytical study with a cross-sectional design was conducted. The study

population consisted of 61 immunization officers who used the ASIK

application during immunization activities in Makassar City throughout the

study period. All eligible immunization officers were included as research

participants using a purposive sampling technique based on predefined

inclusion and exclusion criteria, resulting in a total sample of 61 respondents.

Data were analyzed using the chi-square test with SPSS software to examine

the association between variables. The results showed that perceived usefulness

of the ASIK application was predominantly positive (95.1%), and use behavior

or actual usage of the application was also categorized as positive (96.7%).

However, the chi-square analysis indicated no significant association between

perceived usefulness and use behavior of the ASIK immunization application

(p = 0.903). In conclusion, perceived usefulness did not significantly influence

the actual usage behavior of the ASIK application in immunization activities in

Makassar City.
