Reliable public transportation services are a key
prerequisite for urban mobility and quality of life. In Surabaya, the City
Government through the Transportation Agency has developed the Suroboyo Bus and
Trans Semanggi programs to address congestion, the limited availability of
public transport, and the need for safe, comfortable, and environmentally
friendly mobility. However, complaints still arise regarding inadequate
facilities, irregular schedules, and suboptimal service communication,
indicating the need for a service performance evaluation from the users’
perspective. This study aims to analyze the service performance of Suroboyo Bus
and Trans Semanggi at the Surabaya City Transportation Agency using the five
public service performance indicators proposed by Dwiyanto, namely
productivity, service quality, responsiveness, responsibility, and
accountability. The study employs a quantitative approach with the Importance
Performance Analysis (IPA) method. Data were collected through a 1–5 Likert
scale questionnaire administered to 151 users of Suroboyo Bus and Trans
Semanggi selected randomly. The analysis was carried out by calculating the
level of conformity, the gap between expectation scores and performance scores,
and mapping service attributes using a Cartesian diagram.
The results show that the average expectation (importance)
score is 4.18 and the average performance score is 3.86, with an overall gap of
–0.32, indicating that the service performance of Suroboyo Bus and Trans
Semanggi has not yet fully met public expectations. The service quality and
accountability indicators display the largest gaps and therefore need to be
prioritized for improvement, while responsibility emerges as the
best-performing indicator. Based on the IPA mapping, three attributes fall into
Quadrant I (top priority), namely the friendliness and professionalism of
staff, the adequacy of on-board facilities, and the transparency of official
information related to schedules and service changes. A total of 13 attributes
are located in Quadrant II (to be maintained), 13 attributes in Quadrant III
(low priority), and one attribute in Quadrant IV (excessive). Overall, Suroboyo
Bus and Trans Semanggi have provided services that are reasonably productive,
responsive, and relatively equitable, but still require strengthening in
service quality, accountability, and supporting infrastructure in order to more
effectively encourage a shift towards public transport use in Surabaya.Top of Form
