Abstract

The increasing adoption of artificial intelligence (AI)–based information systems in service sector organizations in Indonesia raises challenges related to user trust in organizational decision-making. This study analyzes the factors influencing user trust in AI-based information systems and examines the role of trust in enhancing decision-making quality and users’ intention to rely on AI. Using a mixed-methods explanatory sequential design, quantitative data were collected through a survey of 60 AI system users in service organizations, complemented by in-depth interviews with six key informants. Quantitative analysis employed linear regression and mediation analysis, while qualitative data were thematically analyzed. The results indicate that AI transparency, system explainability, and perceived reliability positively affect user trust, whereas perceived risk has a negative effect. User trust significantly improves decision-making quality and intention to rely on AI and mediates the relationship between AI system characteristics and decision-making outcomes. This study contributes to the literature on trust in AI-based information systems and offers practical insights for service organizations in designing and managing AI implementations that foster user trust.

Abstract

Effective mine production planning is critical for improving operational performance in open-pit mining, particularly amid challenges related to heavy equipment management, limited working time, and rising operational costs. This study aims to optimize mine production planning to enhance operational efficiency through the application of quantitative optimization models. Using an applied quantitative approach within an operations research framework, the research is based on a case study of an open-pit coal mine in East Kalimantan, Indonesia. Secondary production data, including equipment capacity, effective working time, operational costs, and production targets, were analyzed. A linear programming model was developed to minimize production costs and maximize equipment utilization under operational constraints. The results demonstrate that the proposed optimization model yields more efficient production planning than existing practices, as reflected in reduced operational costs and improved equipment utilization without compromising production targets. This study provides practical recommendations for mine managers and contributes theoretically to the application of operations research in mining production management.

Abstract

The growing demand for sustainable banking operations requires strong internal risk governance as a foundation for long-term sustainability. This study analyzes the influence of risk awareness and risk management culture on sustainable banking operations in conventional commercial banks. Using a quantitative explanatory approach, data were collected through structured questionnaires distributed to 80 employees of conventional commercial banks in Palembang and analyzed using multiple linear regression. The results indicate that risk awareness has a positive and significant effect on sustainable banking operations, while risk management culture exerts a stronger and more consistent influence. Simultaneously, both variables significantly support banking sustainability. These findings confirm that sustainable banking is shaped not only by regulatory compliance but also by the internalization of risk management values, behaviors, and culture within organizations. This study contributes to the banking risk management literature and provides practical insights for bank managers in developing sustainability strategies through the strengthening of risk culture.

Abstract

The adoption of sustainable land management (SLM) practices by smallholders is a critical issue in agricultural environmental economics, given land degradation pressures and limited household economic capacity. This study analyzes smallholders’ economic behavior in adopting SLM and identifies key economic factors influencing their decisions. Using a mixed-methods approach, data were collected from a structured survey of 60 smallholders in Malang Regency, East Java, and in-depth interviews with five key informants. Quantitative data were analyzed with descriptive statistics and logit regression, while qualitative data were thematically analyzed. Results show that farming income, adoption costs, access to agricultural information, and risk perception significantly affect adoption decisions. These findings indicate that smallholders act economically rationally, weighing trade-offs between short-term profits and long-term sustainability. The study contributes to environmental economics literature by highlighting the need for incentive policies aligned with smallholders’ economic realities to promote effective adoption of sustainable agricultural practices.

Abstract

Financial fraud remains a significant issue in Indonesia’s MSME ecosystem, generally driven by weak financial governance and low internalization of ethical values in accounting practices. This study examines the influence of accounting ethics on fraud prevention in MSMEs by analyzing the relationship between ethically based accounting practices and fraud prevention mechanisms. Using a quantitative explanatory research design, data were collected through structured questionnaires from 150 MSME financial owners and managers selected via purposive sampling and analyzed using multiple linear regression. The results show that accounting ethics—reflected in integrity, objectivity, transparency, and accountability—have a positive and significant effect on fraud prevention. These findings confirm that accounting ethics function not only as a normative framework but also as a practical mechanism to strengthen fraud prevention efforts, providing practical implications for policies and programs promoting integrity-based financial governance in MSME development.

Abstract

Sedentary lifestyle among students is increasingly prevalent and is associated with decreased physical fitness and a higher risk of early non-communicable diseases (NCDs). This study used a systematic literature review following PRISMA guidelines by analyzing observational and experimental studies from reputable databases. The results indicate that sedentary behavior significantly reduces cardiorespiratory fitness and muscular strength and increases the risk of obesity, metabolic disorders, and cardiovascular diseases, while higher physical fitness levels act as a protective factor. Therefore, reducing sedentary lifestyle through increased physical activity from an early age is an important preventive strategy to lower the long-term risk of NCDs.
