Abstract

Financial inclusion played an essential role in increasing the nation's welfare. Therefore, it is crucial to increase financial literacy since the literacy index in Indonesia is still 38,03%. Stock market investment had the lowest contribution toward the level of literacy index. The advancement of ICT and the penetration of internet users support the spreading of financial information among the young generation. Due to its low literacy rate, Indonesians are still vulnerable to false financial information, leading to investment fraud. Gamification is chosen as an alternative method in taking advantage of interactive game development that can easily download via smartphone. The gamification system design, which is named GASING, gives the younger generation adequate information related to secure financial investment. The target game user of GASING is high-school students. The feature of the GASING that offer attractive UI/UX design was expected to increase the knowledge of high-school students in learning stock investment. The usage of GASING gamification was also expected to increase more young generation participation in the Indonesian capital market while simultaneously increasing their knowledge, skills, and confidence in the stock market.

Abstract

This article aims to assess the design, development, and User Experience (UX) of GEJUR, a web-based interactive Learning Management System (LMS) designed to foster green entrepreneurship among youth in Nusa Tenggara Timur (NTT), Indonesia. This study defines green entrepreneurship as entrepreneurial activities that combine economic value creation with environmentally responsible practices that promote sustainability in business. This research enhances the domains of Human–Computer Interaction (HCI) and entrepreneurship education by illustrating how user-centered digital platforms may cultivate youth business competencies while promoting the Sustainable Development Goals (SDGs). GEJUR incorporates interactive learning modules, e-mentoring, and specific cultural features like weaved motifs (pola tenun), providing contextual relevance alongside essential LMS functions. A mixed-methods approach was employed, integrating surveys, Focus Group Discussions (FGDs), semi-structured interviews, and usability testing. Quantitative data were gathered via the System Usability Scale (SUS), whilst qualitative data documented user impressions of obstacles and anticipations. The usability evaluation, conducted with 33 individuals, resulted in a mean SUS score of 48.9, which corresponds to approximately 71.9% of the benchmark score of 68. This positions GEJUR beneath the established threshold, classified as having “poor” usability, although it remains functionally workable. Participants effectively accomplished critical tasks including authentication, course access, and quizzes, and offered favorable feedback regarding the system’s cultural integration. The results highlighted critical areas for enhancement, such as interface uniformity, minimization of response times, and more explicit user feedback. The study finds that GEJUR offers a viable yet improvable foundation for digital entrepreneurship training platforms in underprivileged areas. Subsequent study ought to broaden testing to encompass bigger and more heterogeneous user populations and implement sophisticated UX evaluation criteria beyond the SUS. Through iterative refinement, GEJUR can develop into a scalable platform that facilitates youth empowerment, sustainable business practices, and extensive socio-economic advancement.

Abstract

Amidst the massive growth of online lending and the prevalence of loan default in Indonesia, this research tests an integrated behavioral model to identify its determinants, employing a quantitative PLS-SEM method on 213 online loan users in the Jabodetabek area. Key findings reveal that financial literacy consistently emerges as a significant protective factor. Conversely, the role of personal traits is more nuanced: self-control and materialism primarily influence risk perception rather than directly impacting default behavior. The study also confirms a perception-behavior gap, wherein risk awareness is insufficient to prevent default, while default intention, consistent with the Theory of Planned Behavior, proved to be the strongest proximal predictor of actual default. This study contributes by clarifying these complex behavioral roles and offers actionable implications for regulators and the fintech industry to design more effective risk mitigation strategies.

Abstract

The waste problem requires a multidimensional approach, especially in processing and sorting at the source, in line with the Sustainable Development Goals of achieving zero waste in the future. The waste bank program has been introduced to support waste reduction and the circular economy, but public interest in recycled products remains low. Banten Province, one of the five provinces with the highest waste tonnage in Indonesia in 2022, showed interest of only 19.3%. This study aims to identify the factors influencing public purchase intention of recycled products, with product trust as a mediating variable. Through online questionnaires and data analysis using SEM PLS, involving 158 respondents in Banten Province, it was found that environmental consciousness, environmental concern, perceived value, and perceived risk significantly influence the purchase intention of recycled products. Additionally, these factors also significantly affect product trust. Mediation analysis shows that product trust can mediate the relationship between environmental consciousness and environmental concern with purchase intention, but it is not optimal in mediating the impact of perceived value and perceived risk. Recommendations for environmental activists in Banten Province include increasing the credibility and clarity of information regarding recycled products, as well as ensuring the cleanliness and safety of these products to directly enhance public purchase intention and support the circular economy in Banten Province.

Abstract

Technological advancements have brought innovation in the financial industry with various platforms. Although these platforms are easily accessible, some Indonesians are still reluctant to use them, hence the need for proper introduction and information delivery. Peer-to-peer (P2P) lending platforms need to develop and implement applications that can monitor the activities and increase the productivity of direct sales agents (DSAs) to gain the trust of potential borrowers. This study analyses the influence of perceived usefulness, ease of use, risk, and information quality on the actual behaviour of DSAs when using sales productivity applications with behavioural intention as an intervening variable to be statistically processed using the Structural Equation Method. The questionnaire was distributed to DSAs of Modalku platform. The results showed that DSA's actual behaviour in using the application was significantly influenced by intention to use, perceived usefulness, ease of use, risk, and information quality. Perceived risk has the highest influence.

Abstract

This study addresses a practical decision problem within the melamine industry. Production managers are tasked with determining whether a new Melamine Moulding Compound (MMC) dye is suitable for use, based on testing parameters such as boiling point, processing time, and pressure. Given that these values frequently fall between established expert categories, manual decision-making can be challenging to justify and replicate. Accordingly, this research develops a web-based Fuzzy Sugeno expert system to assess the feasibility of MMC dye. The model incorporates three input variables, each characterized by low, medium, and high fuzzy sets. Expert knowledge is formalized into 27 rules employing zero-order Sugeno consequents for three classes: not feasible, conditionally feasible, and feasible. The system has been implemented as a PHP and MySQL application and is accessible via a publicly available login page. An illustrative example involving MMC103—boiling point of 165 °C, processing time of 65 seconds, and pressure of 55 bar—indicated medium and high membership values across all three parameters, activating eight rules. The aggregate firing strength was calculated as 3.00, the weighted consequent sum amounted to 80.00, and the final Sugeno score was 26.67. This score categorizes MMC103 as feasible. The results demonstrate that the model not only provides a classification label but also displays memberships, active rules, rule consequents, and the final computation, thereby enabling verification by the production manager. Furthermore, the study includes an English version of the application interface with privacy masking features for user data.

Abstract

This study aims to develop and evaluate the GEJUR electronic catalog as a continuation of a digital entrepreneurship learning platform that supports market access for young entrepreneurs in East Nusa Tenggara, Indonesia. The research contributes a user-data-informed approach to extending entrepreneurship education into a practical digital marketplace by integrating local cultural identity, product promotion, and business support within a single web-based platform. A descriptive quantitative design combined with information system development was employed, consisting of requirement analysis, platform design and implementation, and user evaluation. The platform was developed using modern web technologies and incorporates seller and buyer registration, product management, tutorial materials, local cultural design elements, and communication-based transaction support. The study involved forty-one young entrepreneurs selected through purposive sampling. Data were collected using questionnaires that measured usability, user experience, digital literacy, and perceived business impact, supported by qualitative user feedback. The research presents a methodology framework, system architecture, database design, user interface illustrations, descriptive respondent profiles, reliability and validity assessment, usability evaluation, and thematic analysis. The findings indicate that the platform achieved an average usability score of 64.8, demonstrating that it is functional and approaching an acceptable level of usability while highlighting the need for improvements in user onboarding, interface consistency, navigation, and transaction guidance. Participants also perceived the platform as beneficial for increasing product visibility, expanding market access, and promoting local cultural products. These findings demonstrate the potential of integrating digital learning and electronic commerce within a single ecosystem to strengthen youth entrepreneurship and regional economic development while providing a foundation for future enhancements, including secure digital payment integration, logistics support, and broader implementation.
