Abstract— Technological developments have continued to
develop until now and the community has even made it a necessity,
one of which is the motorized vehicle tax payment processing
service, where payments can be made via e-banking or a
predetermined Bank ATM. Because of this, users believe that

there is little to no difference between traditional Samsat and E-
Samsat, the user returns to the Samsat Office to obtain validation

of vehicle registration certificates (STNK). User satisfaction is
formulating user satisfaction and comparing expectations and
reality as follows: if expectations < reality then very satisfied, if
expectations = reality then satisfied and If expectations > reality
then not satisfied. The purpose of this study is to find out what
factors influence user satisfaction in the North Sumatra E-Samsat
application and recommendations to application developers so
that user satisfaction does not decrease. This study uses
quantitative methodology. Quantitative is a research method in
which data collection techniques are carried out through surveys
and questionnaire instruments and data analysis is carried out
statistically. This study will use the End User Computing
Satisfaction method, the EUCS method was chosen because it has
5 variables of content, accuracy, format, ease of use, and timeliness
to measure factors that influence user satisfaction from
information systems. The results of the discussion from this study
using the EUCS method each variable get a score of 4 (satisfied)
out of 5 total scores. But it's not perfect yet, so some improvements
are needed to further increase user satisfaction.
