Abstract

Service quality is the comprehensive support provided by system developers to users to ensure safety, comfort, empathy and responsiveness in meeting user expectations. There are still complaints about the Maxim application in the Google Playstore review from January 16 to February 12, 2024, inaccurate pick-up or destination, inconsistent prices, slow service response so that users have difficulty getting solutions to problems. Supported by the INDEF (Institute for Development of Economics and Finance) survey on DataIndonesia.id that the popularity of Maxim's services is lower than Gojek and Grab. Thus, it is essential to employ the E-Servqual approach to perform research to determine whether the services have satisfied users. Because its dimensions are pertinent and completely satisfy the requirements of assessing the quality of electronic services, E-Service Quality is the most thorough and integrative online service quality model. Efficiency, fulfillment, system availability, privacy, responsiveness, compensation, and interaction are the seven factors used, while user satisfaction is the dependent variable. This kind of study collects data using nonprobability sampling approaches in conjunction with quantitative methods. wherein demographic components are chosen according to specific standards that are pertinent to the study's goals. Considering the findings of the analysis, the 7 proposed hypotheses consisted of 3 accepted hypotheses and 4 rejected hypotheses because the significance value < alpha (? = 0.05) and 4 hypotheses rejected because the significance value > alpha (? = 0.05. Overall, the quality of Maxim's service towards user satisfaction is not good in terms of the variables of efficiency, system availability, responsiveness, and contact. It is hoped that there will be improvements in the Maxim application such as application usage, application functions on the displayed page, application response, and contact services for communication

Abstract

The village information system has experienced significant growth, but research focusing on user adoption behavior in the Kalurahan Murtigading government area remains limited. Additionally, most studies use a single theoretical framework to explore this behavior. Addressing this gap, this study applies the UTAUT-2 framework to analyze the key factors influencing behavioral intention to use the village information system among the Kalurahan Murtigading government, with the addition of perceived security and epistemic value as other influencing factors. The study employs a survey approach with a cross-sectional design, and the proposed conceptual model was tested using partial least squares-structural equation modeling (PLS-SEM) analysis on 38 samples, with no issues of non-response bias (NRB) and common method bias (CMB). The results indicate that the UTAUT-2 constructs, along with the additional factors, significantly influence behavioral intention, with social influence, effort expectancy, and epistemic value being the top three factors affecting behavioral intention. These findings can also assist stakeholders in developing effective strategies to encourage more individuals, especially in the Kalurahan Murtigading government area, to adopt the village information system.

Abstract

Micro, Small, and Medium Enterprises (MSMEs) are the backbone of Indonesia’s economy, contributing significantly by absorbing 96.92% of the workforce. MSMEs must adapt to technological advancements, particularly in digital payment systems. The Quick Response Code (QR Code) has been introduced as a payment innovation in Indonesia, with the implementation of the Quick Response Code Indonesian Standard (QRIS) mandated by Bank Indonesia for all payment system providers starting January 1, 2020, under PADG No. 24/1/PADG/2022. Data from ASPI shows a 62.95% increase in QRIS adoption by merchants in 2022 compared to the end of 2021. The Special Region of Yogyakarta, particularly Bantul Regency, contributes significantly to the region's GDP, accounting for 15.18%. It is crucial to encourage MSMEs in Yogyakarta to embrace economic digitalization through the use of QRIS in sales transactions. This study analyzes the push-pull-mooring (PPM) factors that influence MSMEs' switching intentions to adopt QRIS. Push factors refer to negative aspects of the old service, pull factors represent positive attributes of the new service, and mooring factors are barriers to switching intention. The research employs the PPM framework and analyzes data using the SEM-PLS method through SmartPLS 4.1. The sample consists of 100 respondents who meet the criteria of MSMEs that have never used QRIS and do not keep sales transaction records in their business. The results indicate that three hypotheses show significant influence, while four are not significant. The latent variables that significantly affect switching intention are saving time, perceived lack of transaction records, and perceived trouble. The analysis reveals that pull factors have a relatively higher impact on switching intention compared to push factors. Mooring factors, represented by the latent variable of habit, show no significant effect on switching intention.
