Abstract

While the use of mobile wallets in Indonesia has increased, the country remains behind other ASEAN nations, notably Thailand and Vietnam. This study seeks to investigate the factors influencing Indonesians’ intention to continue using mobile wallets by incorporating the Technology Acceptance Model with social interactions, particularly social connectedness and social influence. This study aims to offer a theoretical contribution by exploring the role of the social interactions, specifically social connectedness, which has not been previously investigated in mobile wallets adoption research. The data collection process involved surveying mobile wallet users in key urban areas in Indonesia, yielding a total of 228 data. The research model underwent testing through the PLS-SEM methodology, revealing that the intention of Indonesians to continue utilizing mobile wallets is influenced by ease of use, benefits, and social connectedness. This study also presents recommendations for relevant stakeholders to persuade users to maintain their use of mobile wallets.

Abstract

A country's export level contributes greatly to its economy. Despite accounting for 99% of all companies, the contribution of small and medium-sized enterprises (SMEs) to national export in Indonesia is quite low, at 15.6%. The relatively low contribution of SMEs to export encourages scholars to look at the factors that impact or discourage SMEs from exporting their products. This study aims to build a model of internationalization adoption, i.e. export to foreign markets, based on the concept of innovation diffusion, with five dimensions: relative benefits, compatibility, complexity, trialability, and observability, in order to gain a better understanding of how internationalization as an innovation spreads in SMEs. The survey approach is employed, with questionnaires sent to SMEs in Bandung, and the data obtained is used to evaluate the model. According to the findings of the data analysis, relative benefits complexity, trialability, and observability all have a substantial impact on SMEs' intentions to export.

Abstract

PT X is a multinational B2B automotive company that provides large trucks. Based on truck sales data from 2019 to 2021, PT X has experienced a decrease in truck sales. In July 2021, 2 out of 6 transactions failed because customers preferred to buy trucks from other companies. PT X suspects issues with customer loyalty. This study aims to evaluate customer loyalty levels based on factors influencing them. The research phase begins with the construction of research models and questionnaires containing rating questions on perceived value, product quality, service quality, corporate image, customer satisfaction, and customer loyalty. Questionnaires were distributed to customers who had purchased trucks from PT X between October 2021 and November 2021. Data processing is conducted using the PLS-SEM method to derive research conclusions. Based on the results of data processing, it was found that the factors affecting customer loyalty are product quality, corporate image, and customer satisfaction. Suggestions include a focus on these three factors and improvement in the spare part procurement system, with the hope that customer loyalty levels and truck sales will increase.

There are many food businesses spread across Indonesia, one of which is Restaurant X. The problem found was that there was a decrease in revenue at Restaurant X’s income starting from 2020 to 2023, causing difficulty in achieving targets every month. The purpose of this research is to identify and analyze the key factors that influence customer repurchase intentions at Restaurant X. The decrease in revenue occurred due to a decrease in the number of customers. Therefore, the purpose of this study is to determine the factors that can influence customer repurchase intentions at Restaurant X. In the research there are several variables, namely service quality, food quality, sacrifice, and customer satisfaction. Data collection was carried out using a questionnaire with a sampling technique in the form of convenience sampling. Data processing was carried out using the PLS-SEM (Partial Least Square-Structural Equation Model) method. This research succeeded in proving that service quality, food quality, and sacrifice influence customer satisfaction which then influences repurchase intention.

Abstract

As a way to achieve sustainable development, it is important to develop a tool for assessing sustainability of Indonesian universities. There is one tool created by an Indonesian university, which have been utilized by 1,183 universities worldwide. However, the participation of Indonesian universities in sustainability assessment using this tool is considered very low, only 3.12% or about 145 universities in Indonesia. This statistic calls for an effort to develop a new assessment tool that accommodates the context of Indonesian universities. The objective of this research is to develop a sustainability assessment tool that is effective, relevant with the context of Indonesian universities and includes a data input system that is simple to use. The research involves identifying relevant sustainability dimensions, determining indicator criteria suitable for Indonesian context, designing easy data input, and evaluating the validity and reliability of the tool. This study uses a literature review of 29 current measuring tools used globally, which revealed four primary areas (i.e. environment, economics, education, and social). According to this preliminary study, the typical measurement tool averagely has forty indicators. Moreover, it is observed that current tools have some unsuitable indicators to Indonesian context (i.e. infrastructure, environment, and information). This study has streamlined the tool to three primary areas (i.e. environment, social, and education) and 18 assessment indicators. As a follow up study, expert talks, pairwise comparison analysis, and the design and testing of the sustainability assessment tool will be carried out.

Abstract

Active involvement of all sectors of society is essential for effective waste management, particularly in addressing non biodegradable waste. Although the 3R (Reduce, Reuse, and Recycle) framework has been widely promoted and supported by the establishment of community-based waste banks to facilitate recycling activities, public participation in utilizing these facilities remains limited. This study aims to investigate the determinants of waste bank utilization intention by extending the Theory of Planned Behavior (TPB) with stimulus-based factors derived from the Stimulus Organism–Response (SOR) framework. Data were collected through a structured questionnaire survey involving 175 respondents. The variables examined include attitude, subjective norms, perceived behavioral control, environmental knowledge, and waste bank knowledge. Data analysis was conducted using Partial Least Squares Structural Equation Modeling (PLS-SEM). The results show that attitude, subjective norms, and perceived behavioral control have a significant positive effect on waste bank utilization intention, with attitude being the most influential determinant (β = 0.353). In addition, environmental knowledge (β = 0.426) and waste bank knowledge (β = 0.392) significantly influence attitudes toward waste bank utilization. The proposed model demonstrates moderate explanatory power, explaining 64.3% of the variance in waste bank utilization intention and 50.1% of the variance in attitude. Overall, these findings indicate that the extended TPB effectively explains waste bank utilization intention in the Pantai Indah Kapuk area, with knowledge serving as a key antecedent of attitude, which in turn contributes to waste bank utilization intention.
