academic English literacy among Indonesian undergraduates. Using a quantitative quasi-experimental design with a pre-test and post-test control group, 60 students were divided into experimental and control groups. Instruments included comprehension tests, learner autonomy questionnaires, and rubric-based writing assessments. Results showed significant improvements in the experimental group. Academic text comprehension increased, particularly in vocabulary mastery (+12%), rhetorical structures (+15%), and recognition of formal registers (+10%). Copilot usage positively predicted learner autonomy, with gains in goal-setting (+14%), strategy selection (+11%), and self-evaluation (+13%). Writing performance also improved, especially in coherence (+13%), argumentation (+16%), and adherence to conventions (+12%). The findings confirm Copilot’s role as both corrective aid and developmental partner, fostering academic literacy and learner autonomy. Implications suggest integrating AI tools into EFL curricula to strengthen academic discourse and independent learning.

the process of discovering their identity, are highly vulnerable to environmental and social influences that can lead to drug abuse. This study aims to determine the efforts made by the National Narcotics Agency (BNNK) of South Tapanuli Regency in preventing and handling drug abuse among adolescents in the South Tapanuli area. This study used a qualitative approach with field research methods. Data were obtained through observation, interviews, and documentation. Informants in this study were employees of the BNNK of South Tapanuli, specifically the Prevention and Community Empowerment (P2M) team and the rehabilitation team. The results of the study indicate that prevention efforts are carried out through socialization, counseling, education, and collaboration with various parties in supporting the Prevention, Eradication of Drug Abuse and Illicit Trafficking (P4GN) program. Meanwhile, handling efforts are carried out through assessment, counseling, rehabilitation, and post-rehabilitation monitoring for drug abusers. The obstacles faced include low awareness in some communities, the influence of social circles, stigma against former drug users, and developments in technology and social media. Therefore, collaboration between families, schools, communities, and the government is necessary to support successful efforts to prevent and address drug abuse in teenagers.
Abstract:The rapid development of digital financial technology has significantly transformed investment activities by providing easier access to financial markets through digital investment applications. This study aims to explore…
e the perceptions and experiences of beginner investors in making investment decisions in the digital era. Using a qualitative research approach with a phenomenological perspective, data were collected through semi-structured interviews with beginner investors who actively use digital investment applications. The collected data were analyzed using thematic analysis to identify patterns and themes related to investors’ experiences and decision-making processes. The findings reveal that investment decision-making among beginner investors is influenced by several interconnected factors, including the accessibility and usability of digital investment platforms, the influence of social media and online communities, the development of financial literacy, and psychological experiences related to investment gains and losses. Digital investment applications play a crucial role in lowering barriers to market participation by providing user-friendly interfaces and accessible financial information. However, reliance on social media as a source of investment information may also expose investors to misinformation and speculative investment behavior. In addition, emotional responses such as confidence, fear, and uncertainty often influence investment decisions among beginner investors. Overall, the study highlights that investment decision-making in the digital era is a multidimensional process shaped by technological accessibility, social influence, financial knowledge, and psychological factors. These findings contribute to a deeper understanding of investor behavior in digital financial environments and emphasize the importance of financial education and responsible investment practices.

igital competencies function as a critical mechanism shaping labor productivity, innovation capacity, and economic performance. Using cross-sectoral data and workforce survey evidence, the study analyzes the extent to which digital skills contribute to workforce adaptability and organizational efficiency. The findings reveal that higher levels of digital literacy significantly enhance workforce development by improving skill alignment, fostering innovation, and increasing competitiveness across industries. At the macro level, these improvements translate into measurable contributions to economic growth through productivity gains and structural transformation. Furthermore, the study underscores the importance of multi-stakeholder collaboration among educational institutions, industry, and government in designing integrated digital literacy programs. Such coordinated efforts are essential to ensure sustainable skill development and long-term economic resilience. This research contributes to the literature by providing an integrated perspective that explicitly links digital literacy to both workforce development and macroeconomic outcomes, offering practical implications for policymakers and stakeholders in shaping inclusive and sustainable growth strategies.
Abstract:This study aims to analyze the interpretations, behaviors, and preferences of gold investment among civil servants (PNS) of the South Sulawesi Provincial Government in facing economic volatility and inflation. Using a descriptive…
scriptive qualitative method with a case study approach, this study collected data through in-depth interviews with 13 informants consisting of active civil servants, retirees, and financial practitioners, supported by secondary data analysis. The results show that PNS interpretations of gold are multidimensional, namely as an effective life buffer and hedge against inflation, as well as an instrument for fulfilling cultural obligations (uang panai' and siri'). This study found a transformation in investment behavior from gold jewelry to gold bars and digital savings, driven by mental accounting mechanisms through payroll deduction systems to discipline spending. In conclusion, the local culture of Bugis-Makassar interacts dynamically with modern financial literacy, creating a hybrid investment pattern supported by sharia compliance and the integration of regional banking technology.
Abstract:A mid-sized school district could achieve annual savings of $2.3 million—sufficient to support significant teacher salary increases—by streamlining procurement processes and reducing the number of suppliers from 87 to 12.…
o 12. This practical success reflects the operational rigor of enterprise models, exemplified by Walmart Business, which has been successfully tailored for K-12 education. The study indicates a systemic crisis. Sixty-eight percent of U.S. districts experience a 19% loss of their non-payroll budgets due to procurement inefficiencies, resulting in significant financial losses for classrooms attributed to fragmented purchasing and compliance deficiencies. The study employs a rigorous mixed-methods analysis, incorporating in-depth case studies from 35 districts, a national survey of 300 procurement officers, and comprehensive spend analytics, to illustrate the transformative outcomes associated with enhanced procurement maturity. Consolidated purchasing platforms reduce processing costs by 53% and capture 92% of rebates. Additionally, the new Procurement Simplicity Scorecard predicts 79% efficiency gains, offering leaders a practical diagnostic tool. This study presents two validated innovations: the K-12 Procurement Maturity Model, which delineates a phased progression from fragmentation to strategic excellence, and the Zero-Waste Playbook, which details tactical measures for waste elimination. The evidence indicates that reengineering procurement is not merely an administrative concern; it represents a significant, frequently neglected mechanism for generating billions in savings by 2025. These funds have the potential to enhance arts programs, update outdated STEM laboratories, and recruit and retain high-quality educators. This research offers a definitive framework for districts aiming to transform waste into opportunities for equity.
Abstract:The increased integration of operational technology (OT), Internet of Things (IoT), and business IT systems has allowed sophisticated attackers to circumvent isolated security features and launch cross-platform assaults.…
Current fragmented techniques, with discrete detectors monitoring Modbus, Kubernetes, MQTT, or other domain-specific protocols, cannot handle cross-system risks. These methodologies overlook 68% of multi-vector marketing that uses both physical and digital channels. This study introduces a transfer learning architecture to integrate detection capabilities by correlating threats across protocols, devices, and settings. The architecture generates a unified feature space that extracts behavioral semantics from industrial control system logs, cloud telemetry, network traffic, and device-level signals to produce protocol-agnostic threat representations. Adversarial domain adaptation and semantic graph embeddings enable cross-domain knowledge transfer with minimum retraining. Security teams may now discover kill chains like infected cloud containers preceding illegal PLC command execution every 23 minutes. Validated against real-world attack datasets from water treatment facilities (OT) and cloud infrastructure (IT), the system achieved 93.4% cross-platform attack recall, a 41.3 percentage point improvement over prior methodologies. It reduced OT data labeling by 89% and false positives by 93.5%. This paradigm shift transforms threat correlation from a reactive, domain-specific process to adaptive intelligence, boosting resilience for critical infrastructure, industrial ecosystems, and smart environments facing cyber-physical hazards. The framework's practical validation in energy, industry, and vital infrastructure shows its importance in protecting an increasingly linked world.
Abstract:This study examines the factors that affect the exchange rate of the rupiah against the US dollar in Indonesia between 2013-2022. The observed factors include interest rates, inflation, and money supply. Annual data was…
used from legitimate sources such as Bank Indonesia and the Central Bureau of Statistics. The results show that interest rates have a significant influence on the rupiah exchange rate, with an increase in interest rates causing a depreciation of the rupiah against the US dollar. Inflation has no significant effect on the exchange rate, although high inflation can affect purchasing power and confidence in the local currency. Money supply also has a significant effect, where an increase tends to cause rupiah depreciation. An increase in money supply causes inflation and decreases purchasing power, thus decreasing the exchange rate of the rupiah against the US dollar

he provision of compensation. So against this, this study aims to show the significance of the effect of compensation on employee work motivation. The population in this study were all employees of PT Bumi Karsa Makassar who received compensation in the form of salary, bonuses, and health benefits, totaling 60 people. The number of samples used was 60 people using saturated sampling theory. Data collection was carried out using questionnaire and documentation methods. The data analysis technique used is multiple linear regression analysis using Statistical Product and Service Solution (SPSS). The multiple linear regression equation produces the equation Y = 0.165 + 0.032X1 + 0.961X2. The results of this study found that compensation variables (financial and non-financial compensation) simultaneously affect work motivation and the F-Count value (4566,330) > F-Table (3.16). The results of the correlation analysis of determination (R Square) of 0.994 which shows that the compensation variable is able to contribute 99.4%. 0.6% is influenced by other variables not examined. The most dominant variable affecting motivation is the non-financial compensation variable among the two compensation variables with a t-count value (48.056) > t-table (1.672). While the financial compensation variable is influential but not significant with a t-count value (1.205) < t-table (1.672).

ot been empirically tested. This study examines whether a flat 3 percent quarterly bonus, applied uniformly across a portfolio of more than three hundred products spanning a 600-fold price range, produces unintended consequences beyond its stated goal of volume growth. A sequential explanatory mixed-methods design is used. The quantitative phase analyses 781 product-quarter observations covering 326 products over eleven quarters from mid-2023 through end-2025. The qualitative phase uses confirmatory interviews with seventeen informants from distributor management and sales teams. The incentive program successfully drives all four sales performance dimensions measured in the study, covering volume growth, revenue share, transaction frequency, and a cumulative growth index, all of which are statistically significant. However, higher-priced products attract significantly fewer transactions per quarter and grow more slowly over time. Seven of eight hypotheses are supported. Qualitative findings confirm that the incentive effect adds to total selling activity rather than redirecting it, but transaction attention consistently concentrates on lower-priced products across the eleven-quarter period. The study extends agency theory to a three-party setting and provides the first panel-level evidence of composition effects from a uniform sales incentive in Indonesian B2B distribution.
