The rapid growth of digital marketplaces has fundamentally transformed consumer decision-making processes by intensifying price transparency, product comparability, and information exposure. In highly competitive marketplace environments, consumers are frequently confronted with numerous product alternatives and dynamic pricing structures, which shape how they evaluate options and ultimately decide to purchase. This study examines the effects of product variety and price perception on consumers’ purchase decisions in the context of ROSCA tumbler products sold on the Shopee marketplace. Using a quantitative explanatory approach, this research employs a survey-based design to analyze the relationships among variables and to estimate their relative effects through multiple linear regression analysis. Data were collected from 100 respondents who had previously purchased ROSCA tumblers on Shopee, selected using purposive sampling based on predefined criteria. The research instrument consisted of 15 Likert-scale items measuring product variety, price perception, and purchase decision. Data analysis included descriptive statistics, instrument validity and reliability testing, regression assumption diagnostics, and hypothesis testing using both partial (t-test) and simultaneous (F-test) procedures. The findings reveal that product variety has a positive and significant effect on purchase decisions, indicating that consumers are more likely to finalize purchases when they perceive product options as sufficiently diverse, relevant, and comparable. Price perception also exerts a positive and significant influence and demonstrates a stronger relative effect compared to product variety. This result underscores the central role of perceived price fairness, competitiveness, and value-for-money in shaping purchase decisions within transparent and highly competitive marketplace settings. Simultaneously, product variety and price perception explain a substantial proportion of variance in purchase decisions, highlighting their combined importance as key marketing stimuli. These findings contribute to the literature on digital consumer behavior by providing empirical evidence from a specific marketplace–product context and offer practical implications for sellers and brand managers in optimizing assortment design and pricing strategies to enhance conversion rates in online marketplaces

The increasing integration of Cyber physical Systems (CPS) into industrial environments has highlighted the need for secure, scalable, and efficient cryptographic key management systems. Traditional centralized key management protocols are often limited by vulnerabilities such as single points of failure, scalability issues, and significant overhead. Blockchain technology presents a promising solution to these challenges by leveraging decentralization, immutability, and transparency to enhance security and efficiency in CPS. This study investigates the use of blockchain based cryptographic key management systems, focusing on smart contracts for automated key distribution and rotation. Experimental results demonstrate that blockchain based systems significantly improve system integrity, auditability, and resilience, offering enhanced protection against cyber-attacks and reducing the risks associated with centralized systems. Blockchain’s decentralized architecture eliminates the need for a central authority, making it more resistant to tampering and operational failures.

Blockchain based solutions have the potential to transform the security landscape of industrial environments, offering greater robustness, reliability, and trust.

This study analyzes the juridical implications of delegated authority in the context of business license signing by heads of regional offices acting on behalf of regents. Using a qualitative approach with library research, the paper explores the legal foundation, validity, and administrative consequences of delegation within local governance. The findings indicate that delegation of authority is a legitimate administrative mechanism recognized under Indonesian law, particularly within Law No. 23 of 2014 concerning Regional Government. However, its implementation frequently lacks procedural clarity, leading to potential legal defects (ultra vires) in administrative decisions. The study emphasizes that the validity of business permits depends on both formal and substantive fulfillment of delegation requirements through explicit legal instruments such as regional head decrees. Improper delegation not only invalidates administrative acts but also undermines legal certainty and public trust in local governance. Theoretically, this research contributes to strengthening the doctrine of state administrative legality, while practically, it provides recommendations for standardizing delegation mechanisms to enhance transparency, accountability, and legal compliance in regional public service delivery.

Explainable Artificial Intelligence (XAI) has become a critical area of research within artificial intelligence, focusing on improving the transparency and interpretability of machine learning (ML) models, often referred to as "black-box" models. The need for XAI techniques arises from the inherent complexity of ML models, which can make their decision-making processes difficult for users to understand. This study investigates various XAI techniques, including LIME (Local Interpretable Model-agnostic Explanations) and SHAP (SHapley Additive exPlanations), to assess their impact on model interpretability without significantly compromising predictive performance. A comparative experimental design was used, applying these XAI methods to different ML models, including deep neural networks and ensemble methods, within large-scale enterprise data analytics systems. The results indicate that XAI methods significantly enhance model transparency and decision traceability, allowing users to understand the influence of individual features on predictions. While a slight reduction in predictive accuracy was observed, especially with simpler models, the trade-off between interpretability and performance was deemed acceptable, particularly in fields requiring transparency, such as healthcare, finance, and autonomous systems. The use of XAI in enterprise data systems has practical implications for fostering trust and enabling informed decision-making among stakeholders. Furthermore, the study discusses the challenges and limitations of applying XAI techniques, such as complexity, scalability, and model-specific limitations. Future research is suggested to focus on developing more scalable and efficient XAI methods, enhancing their applicability across various model types, and addressing the challenges of real-time applications. This will be crucial in ensuring the widespread adoption of XAI in critical domains, promoting the ethical use of AI while maintaining predictive accuracy.

This study discusses the legal problems faced by tobacco farmers in Sukorejo Village, Kotaanyar District, Probolinggo Regency due to the closure of large tobacco warehouses that force them to depend on middlemen. This condition causes legal uncertainty, an imbalance in the bargaining position, and alleged violations of the principle of healthy business competition, thus having a direct impact on the economic sustainability of farmers. The focus of this research is to describe the practice of business competition and its impact on tobacco farmers and explain the form of legal protection from the perspective of business competition law and sharia economic law. The research method used is empirical law with a sociology approach to law and legislation, through observations, interviews, and documentation from farmers, middlemen, and factories. The results of the study show that there is dominance of middlemen in cooperation with large factories so that farmers lose freedom in determining prices. This condition does not reflect the principles of fairness and transparency in business competition. Legal protection is still weak because there is no regulation of the basic price or a definite buying and selling mechanism. In the perspective of sharia economic law, the practice violates the principles of al-adl (justice) and al-amanah (honesty). In conclusion, preventive legal protection is needed in the form of price regulation and the establishment of marketing cooperatives, as well as repressive protection through law enforcement against unfair business competition practices.

Corruption is an extraordinary crime that has multidimensional impacts on a country’s social, economic, and political life. In Indonesia, corruption cases not only cause financial losses to the state but also undermine public trust in the government and weaken the rule of law. This study examines the case of social assistance (bansos) corruption during the Covid-19 pandemic involving former Minister of Social Affairs, Juliari P. Batubara, who was proven to receive bribes from vendors providing social assistance amounting to tens of billions of rupiah. The study aims to understand the regulation of corruption under Indonesian law, the chronology of the bansos corruption case, and the criminal liability of the former Minister of Social Affairs. The analysis shows that this case not only caused financial losses to the state but also inflicted social suffering on the poor affected by the pandemic and reduced the government’s legitimacy. The prison sentence, fines, and obligation to pay state compensation imposed on Juliari affirm the principle of criminal accountability, while digital-based reform in social assistance distribution and multi-layered supervision serve as preventive measures to curb future corruption. This study emphasizes the importance of transparency, accountability, and strict law enforcement in combating corruption in Indonesia.
