Abstract

Improving information systems is essential to increase user satisfaction which then has a positive impact on the institution. This study aims to measure the importance and performance of website service quality attributes on the i-Gracias ITTP using Importance Performance Analysis. This study integrate e-ServQual and WebQual to measure the level of student satisfaction with i-Gracias as a web-based information system service comprehensively. Generally, the satisfaction score shows that the performance of quality attributes does not meet the expectations of students as users. Of the 30 quality attributes measured, there is one attribute in quadrant I, 12 in quadrant II, 13 in quadrant III, and 3 in quadrant IV. The attributes that describe the fundamental functions of i-Gracias as an online service system are efficiency, security, fulfillment, information quality, and accessibility. The next priority for improvement for i-Gracias is efficiency improvement and process simplification.

Abstract

Household dependency on Liquified Petroleum Gas (LPG) gas increased Indonesian LPG imports. Therefore, the government encourages the conversion of LPG to induction stoves. However, induction stove users are less than LPG users. LPG stoves, electric stoves, and induction have their advantages and disadvantages. Consumers have different behaviours/responses to each change because each consumer has a diverse/heterogeneous character. This study analyzes the factors influencing consumer intentions to adopt an induction stove. The method used in determining factor analysis is the Structure Equation Model (SEM). The SEM method can model a causal relationship with a complex problem and determine the percentage of influence. The analysis found that the intention to adopt an induction stove was significantly influenced by subjective norm (SN), perceived behaviour control (PBC), and attitude toward behaviour (ATT). PBC is affected considerably by Speed, Maintenance, Cost, and Product Safety. ATT is significantly affected by Speed, Cost, Maintenance, and Security. Alternative penetration policy can be carried out on product heating speed, cost, and product maintenance, which are the variables that most significantly influence the adoption of induction stoves.
