Abstract

General Background: Islamic mutual funds in Indonesia have grown rapidly as ethical investment instruments aligned with sharia principles. Specific Background: Their performance, however, remains sensitive to macroeconomic dynamics such as inflation, BI Rate, and economic growth (GDP). Knowledge Gap: Previous studies often use Net Asset Value (NAV) as a proxy for performance and show inconsistent results, while limited attention is given to ROI as a direct measure of investor returns. Aims: This study aims to analyze the effect of inflation, BI Rate, and GDP on the Return on Investment (ROI) of Islamic mutual funds in Indonesia from 2020 to 2024. Results: Using monthly secondary data and multiple linear regression, the findings show that inflation and the BI Rate have a significant positive effect on ROI, while GDP has a significant negative effect. Novelty: This study differs from previous research by using ROI instead of NAV and includes the latest post-pandemic data, providing more relevant empirical insights. Implications: These results suggest that Islamic mutual funds are more responsive to inflation and monetary policy than to general economic growth, offering valuable considerations for sharia fund managers and policymakers in formulating adaptive investment strategies.Highlight : Inflation and BI Rate positively influence Islamic mutual fund performance. Economic growth shows a negative effect on ROI of Islamic mutual funds. ROI is used as the main metric to assess investment success Keywords: Inflation, BI Rate, Economic Growth, Islamic Mutual Funds, Return on Investment   Ask Chat

Abstract

Background (General): Reading comprehension is a fundamental skill in language learning, essential for academic success and lifelong learning. Background (Specific): In the Indonesian junior high school context, students often struggle with reading comprehension due to limited access to engaging and interactive learning tools. Knowledge Gap: Despite the increasing availability of digital media, empirical evidence on the effectiveness of mobile reading applications like Let’s Read in improving students' reading comprehension remains limited. Aims: This study aimed to examine the effectiveness of the Let’s Read application as a digital learning tool to enhance reading comprehension among eighth-grade students at SMP Muhammadiyah Pagar Alam. Results: Using a quasi-experimental design with pre-test and post-test assessments, findings revealed that students in the experimental group—who used Let’s Read—demonstrated significantly higher gains in identifying main ideas, understanding contextual vocabulary, and making inferences compared to those taught with conventional methods. Novelty: The study provides new evidence on how interactive digital applications can enhance specific reading sub-skills in a formal educational setting. Implications: These results underscore the potential of integrating digital reading platforms into English language instruction to foster more effective and engaging learning experiences for junior high school students. Highlights : Demonstrates the effectiveness of Let’s Read in enhancing reading sub-skills. Fills the gap in research on digital reading tools in Indonesian schools. Recommends integrating digital media to improve English learning outcomes. Keywords: Let’s Read, Reading Comprehension, Digital Media, Junior High School, English Learning

Abstract

General Background: Academic stress is common among university students and can impair concentration. Specific Background: Mindfulness is known to reduce stress but its specific component—acceptance without judgment—has been underexplored in academic contexts. Knowledge Gap: Few studies isolate this component's effect on stress and concentration. Aim: This study examines the impact of mindfulness on stress reduction and concentration improvement among students. Results: Based on a correlational study with 82 students, mindfulness significantly reduced stress (t = 3.913; p < 0.001) but had no significant effect on concentration (t = 0.935; p = 0.353). Novelty: The study isolates the role of acceptance without judgment in academic mindfulness. Implications: Mindfulness is effective for stress management but insufficient alone to enhance concentration, requiring integrated academic strategies.Highlight : Mindfulness is effective in reducing students' academic stress levels. It does not significantly improve students' concentration. A more comprehensive approach is needed to enhance academic focus. Keywords : Mindfulness, Academic Stress, Concentration, University Students, Economics Education

Abstract

General Background: The rise of digital platforms and social media has led to the rapid growth of social commerce (s-commerce), reshaping consumer behavior in emerging markets like Indonesia. Specific Background: While many users engage with platforms like TikTok Shop and Instagram Shopping, sustained intention to use such systems remains varied. Knowledge Gap: Prior research on the Technology Acceptance Model (TAM) often overlooks how Perceived Usefulness (PU) mediates the relationship between Perceived Ease of Use (PEOU) and Intention to Use (IU) in s-commerce contexts, particularly in regions with high digital engagement. Aims: This study investigates whether PU mediates the effect of PEOU on IU among university students with experience using s-commerce platforms. Results: Using SEM-PLS on data from 100 respondents, findings reveal that PEOU has no significant direct effect on IU but significantly affects PU, which in turn significantly influences IU. An indirect path from PEOU to IU via PU is statistically significant. Novelty: The study emphasizes that ease of use alone is insufficient; perceived benefit is critical in motivating continued use in socially driven e-commerce environments. Implications: These findings guide platform developers to prioritize usefulness-oriented features, suggesting that perceived functionality is more influential than interface simplicity in fostering user loyalty.Highlight : Perceived Ease of Use does not directly affect Intention to Use but influences it indirectly. Perceived Usefulness significantly mediates the relationship between ease of use and intention. User intention in social commerce is shaped more by usefulness than technical simplicity. Keywords : Perceived Ease of Use, Perceived Usefulness, Intention to Use, Social Commerce, Mediation Model

Abstract

General Background: Literacy is vital in shaping students' competencies in the information era. Specific Background: SMAN 5 Padang has implemented a literacy program aligned with the Merdeka Curriculum but faces challenges in integration and teacher involvement. Knowledge Gap: Few studies evaluate literacy programs comprehensively using the CIPP model at the high school level. Aims: This study evaluates the school’s literacy program using the CIPP model to analyze its relevance, resources, implementation, and outcomes. Results: The program improved reading interest by 26% and daily reading time by 20 minutes, with 78% of students actively using the literacy corner. However, teacher participation is low, reading materials are less varied, and program integration into learning remains limited. Novelty: The use of the CIPP model provides a structured evaluation rarely applied in literacy programs at this level. Implications: The findings offer strategic input for strengthening literacy programs through teacher engagement, material enrichment, innovation, and digital integration for sustainable impact.Highlight : The CIPP model helps evaluate the literacy program’s planning, implementation, and outcomes comprehensively. The program boosted reading interest but showed weak teacher involvement and limited reading material variety. Strengthening integration into classroom learning and fostering innovation are essential for sustainability. Keywords : School Literacy, CIPP Evaluation, Reading Culture, Teacher Roles, Literacy Innovation

Abstract

General Background: Credit sales are a key strategy in the automotive industry to boost sales volume, yet they pose significant challenges in transaction recording and receivables management. Specific Background: PT. Aksara Motor Medan still relies on a semi-manual accounting information system (AIS) for credit sales, leading to delays in reporting and increased credit risk. Knowledge Gap: Few studies have comprehensively examined the link between semi-manual systems and the rise of bad debts in mid-sized automotive companies. Aims: This study aims to analyze the effectiveness of AIS in supporting accurate recording, reporting, and control of credit sales at PT. Aksara Motor Medan. Results: Findings show that the system is suboptimal, with delayed data updates, weak internal controls, and the absence of an automated reminder system for delinquent customers. Novelty: The study proposes the integration of AIS with a risk-based assessment model using the 5C approach and the COSO framework to strengthen control and risk management. Implications: Full digitalization, structured staff training, automated notifications, and data-driven credit evaluation are recommended to improve operational efficiency and minimize bad debt risks.Highlight : The system is semi-manual, causing reporting delays and credit risk. Arrears rose from 15% to 23.8% in six months. Full digitalization and 5C-based risk analysis are recommended. Keywords : Accounting System, Credit Sales, Bad Debts, Internal Control, Aksara Motor

Abstract

General background: The rapid evolution of digital technology and shifting consumer lifestyles due to globalization have intensified competition among businesses, especially in the food sector. Specific background: Bolu Amor, a local bakery brand in Sukabumi, faces fluctuating sales potentially influenced by the quality of its social media content, brand image, and price perception. Knowledge gap: Previous studies on purchase decisions often examined these variables in isolation or outside the food industry context, leaving a gap in integrated analyses within local bakery businesses. Aims: This study aims to analyze the simultaneous and partial effects of social media content, brand image, and price on consumer purchase decisions for Bolu Amor. Results: Based on a survey of 400 respondents and multiple linear regression analysis, all three variables significantly influenced purchase decisions, with price having the strongest effect. The model explains 8.4% of the variance in consumer decisions (R² = 0.084). Novelty: This research offers a comprehensive integration of digital and perceptual factors affecting purchase decisions in a local food brand, which remains underexplored in current literature. Implications: The findings provide strategic insights for improving digital marketing effectiveness and pricing strategies, guiding local businesses like Bolu Amor to align better with modern consumer behavior.Highlight : Price is the most dominant variable influencing consumer purchase decisions. Social media content, brand image, and price have a significant simultaneous effect. The three variables explain only 8.4% of the variation in purchase decisions. Keywords : Social Media Content, Brand Image, Price, Purchase Decision, Consumer

Abstract

General Background: Culinary tourism plays a crucial role in promoting local culture and supporting the economy in Indonesia. Specific Background: Solo, a city rich in cultural heritage, offers a wide array of traditional souvenirs, making the souvenir business highly competitive. Knowledge Gap: Previous studies mainly focus on the 4P marketing mix, leaving a gap in understanding the broader and more current 9P approach in sustaining small businesses. Aims: This study aims to analyze the implementation of the 9P marketing mix strategy by Toko Oleh-Oleh Era Jaya in Solo in maintaining its business continuity. Results: The findings indicate that all nine elements—Product, Price, Place, Promotion, People, Process, Physical Evidence, Payment, and Packaging—are applied. However, promotion and physical evidence remain under-optimized. Novelty: Unlike earlier research, this study adopts the expanded 9P marketing mix, offering a more comprehensive and adaptive strategy model for small businesses in the digital era. Implications: The study highlights that integrating traditional values with modern marketing strategies enables local souvenir shops to remain competitive and relevant in an evolving marketplace. This research provides valuable insights for other SMEs in similar cultural and economic settings.Highlight : The research analyzes the use of the 9P marketing mix to sustain a local souvenir shop’s business.

Abstract

General Background: In the era of globalization, the culinary industry faces intense competition, requiring companies to implement effective human resource strategies. Specific Background: PT. Younghyun Star in Sukabumi has adopted a reward and punishment system to align employee behavior with organizational goals. Knowledge Gap: However, inconsistencies in reward distribution and ineffectiveness of punishment measures have raised concerns about their actual influence on employee performance. Aims: This study aims to evaluate how the implementation of reward and punishment systems affects employee performance. Results: Using a quantitative, descriptive design and data from 88 employees analyzed with SPSS v26, the findings reveal that both reward and punishment systems have a positive and significant effect on performance, with punishment showing a stronger influence (t = 5.938) than rewards (t = 2.687). Novelty: This research highlights the imbalance between perceived fairness in incentive allocation and the motivational impact of disciplinary actions, offering a contextual insight into behavioral outcomes in a culinary-sector enterprise. Implications: The study suggests that for such systems to be more effective, companies must ensure transparency and consistency, thereby enhancing employee motivation and operational productivity.Highlight : Reward and punishment systems both significantly improve employee performance. Monetary and non-monetary rewards increase motivation, though rule compliance remains low. Strict punishment enhances work discipline, but overuse may hurt emotional stability. Keywords : Reward System, Punishment System, Employee Performance, Human Resource Management, Motivation Tanya ChatG
