Abstract

The rapid adoption of QRIS (Quick Response Code Indonesian Standard) in Indonesia has transformed consumer payment behavior, particularly among Generation Z. However, empirical studies exploring its influence on merchant adoption in the street food sector remain limited. Previous literature has predominantly examined QRIS usage from the perspective of financial inclusion, with minimal attention to the intergenerational dynamics between digital-native consumers and small-scale vendors. This study employed a descriptive qualitative approach with thematic analysis to investigate Generation Z’s usage patterns of QRIS and merchant responses to its implementation. Primary data were collected through semi-structured interviews with ten Generation Z consumers, selected purposively based on their high frequency of QRIS use in food purchases. Two street food vendors were chosen to represent differing age groups and digital literacy levels. Findings indicate that most Generation Z participants consistently preferred QRIS over cash, citing transaction speed, ease of use, and perceived security as key factors. Several respondents stated they would avoid purchasing from vendors without QRIS availability, indicating a demand-driven influence on merchant practices. Merchant responses varied: younger, digitally literate vendors readily adopted QRIS, while older vendors encountered barriers such as limited device access and low digital literacy. The small number of merchant participants reflects the study’s focus on depth of insight rather than breadth of sampling. These results suggest that Generation Z’s payment preferences are accelerating the integration of digital payments in micro and small enterprises, though intergenerational disparities in adoption remain a challenge for broader financial technology inclusion.

Abstract

Phnom Penh is experiencing rapid urbanization, which has led to a proliferation of real estate development projects. However, at the same time, problems facing this market include both overproduction and desperate marketing attempts, as well as the continued mismatch between supply and demand in housing for local residents. Empirical evidence for Cambodia’s capital is scarce, although the influences of property features, marketing strategies, and economic conditions on buyer behavior have been addressed in earlier studies published from Southeast Asia. Drawing on responses from 410 Phnom Penh residents with stable monthly incomes who were diverse in terms of age, gender, education, occupation, and marital status. Both English and Khmer versions of a structured questionnaire were used to collect responses, followed by descriptive statistical analysis of the data to identify the factors that play a dominant role in influencing home purchase intentions and decisions among Phnom Penh residents from different backgrounds. Results indicate that property characteristics (M = 4.03, SD = 0.76) and financial and access factors (M = 3.95, SD = 0.74) were rated highest, while buyer perception and marketing influence (M = 3.72, SD = 0.79) also played a significant role. Among these domains, importance was placed on legal ownership paperwork (M = 4.38, SD = 0.74), safety and security (M = 4.30, SD = 0.71), and affordability and financing options (M = 3.87–4.06), which were revealed to be the key decision-making elements. The research aims to provide contextually relevant recommendations for developers, marketers, financial institutions, and policymakers in Cambodia. Its originality lies in being one of the first Phnom Penh–specific, factor-based empirical studies on homebuyer attitudes, and in contributing to the regional literature on urban housing processes in Southeast Asia, while confirming the main hypothesis that microeconomic and perceptual factors play a significant role in shaping real estate behavior among Generation Z homebuyers.

Abstract

Bruner's theory is particularly notable for its application in mathematics, as it outlines three steps in the teaching process: enactive, iconic, and symbolic. This research aims to implement Bruner's theory in teaching Angles on circles to improve problem-solving skills. The research method is a quasi-experiment with a posttest-only control group design. Using cluster random sampling, two classes from one of the junior high schools in Jakarta were selected as samples: the first as an experimental class of 30 students, who learned using Bruner's theory, and the second as a control class of 31 students, who learned with a conventional approach. The instrument is a mathematical problem-solving test in the form of an essay test of four questions. The questions are given at the end of the lesson, and the instruments have been validated through content validity and empirical validity. The results show that, through t-test analyses, it was found that students’ problem-solving skills, who learn using Bruner's theory, are higher than those of students who learn using conventional methods. It demonstrates that teaching using Bruner’s theory is effective in improving students’ problem-solving skills, particularly in the Area of Angles on circles.

Abstract

It is widely considered that students of English as a Foreign Language get a significant advantage by employing metacognitive tactics. Research that has been conducted in the past has led to a greater knowledge of metacognitive reading methods in the English as a Foreign Language environment. Nevertheless, only a small number of studies have found statistically significant effects on students' reading abilities. As a result, this study anticipated an opportunity to clarify this topic by focusing on the proficiency of high school students in Cambodia who are learning English as a foreign language. The purpose of this study is to investigate the effects of metacognitive strategy instruction on students’ knowledge of these strategies and on their reading performance on standardised tests. The study was attended by 55 English as a Foreign Language high school students enrolled in a public school in Phnom Penh, Cambodia. The students participated for a total of eight weeks. The instruments used for the research were the SORS, the English proficiency reading test, and the lesson plans. In comparison to before the instruction, the students in the Cambodian EFL high school employed the PRS the most after the SORS instruction, followed by the GRS and then the SRS. Additionally, it demonstrated significant gains in both approach awareness (p < 0.01) and International English Language Testing System reading scores (M = 6.65 to 8.13, p < 0.01). The usefulness of specific strategy training in improving the reading performance of students studying English as a foreign language is underscored by these findings. In addition, these results will guide educational methods in Cambodia in the future.

Abstract

This study examines the role of cross-cultural intelligence in the acquisition of keigo (a variety of Japanese polite language) by Indonesian students participating in internship programs in Japan. With a qualitative approach, 9 participants from Institut Prima Bangsa and STBA Yapri were involved through questionnaires and interviews. The results show that students have high motivation to learn keigo, both for professional purposes and to maintain social relationships. Students' cross-cultural awareness can be seen from the understanding that keigo is a language skill as well as a cultural competence. The independent learning strategies used include memorizing, imitating supervisors, and utilizing digital media. The findings confirm that real interactions more influence the acquisition of skills in the workplace than learning in the classroom. This research emphasizes the importance of integrating cross-cultural intelligence in Japanese language learning and recommends the development of curriculum and internship programs based on real practices and digital technology.

Abstract

Reversible thinking is the ability to reverse the order of thinking, understand two-way relationships, and logically and reflectively retrace initial information. This study aimed to describe students’ reversible thinking abilities in mathematical problem solving based on adversity (AQ). The research was conducted using a qualitative descriptive design with 21 eighth-grade students of MTs Annajah Sungai Luar. From these, five subjects were selected purposively to represent the AQ types: quitter, camper, and climber. Data were collected through AQ questionnaires, Test of Reversible Thinking (TTR) essay tasks, and interviews. The results indicated that students with the quitter type were unable to fulfill all aspects of reversible thinking. Camper-type students could fulfill two aspects, namely negation and reciprocity, while climber-type students were able to fulfill all three aspects: negation, reciprocity, and returning to the initial condition. The findings suggest that students with higher AQ demonstrate stronger reversible thinking skills in mathematical problem solving. This contributes to mathematics education by emphasizing the importance of fostering reflective thinking and resilience in the learning process.

Abstract

This study aims to explore the role of insurance agents in increasing microinsurance penetration at PT. Asuransi BRI Life Medan, within the context of the VUCA (Volatility, Uncertainty, Complexity, Ambiguity) era. Although microinsurance, introduced in Indonesia since 2013, has great potential to provide financial protection for low-income communities, public understanding and awareness of the importance of insurance remain relatively low. This condition creates challenges for insurance companies in expanding the reach of microinsurance products. Insurance agents play a crucial role as intermediaries between companies and customers, with responsibilities that include providing education, building trust, and attracting potential customers to microinsurance products. This study employs a qualitative method with a case study approach, conducted through in-depth interviews with insurance agents, marketing managers, and customers of PT. Asuransi BRI Life Medan. The findings reveal that insurance agents utilize various communication channels, both digital and conventional, to introduce and promote microinsurance products to the public. However, agents still face challenges in improving financial literacy and building trust in the benefits of insurance products. These findings underscore the importance of strengthening agents’ capacity and developing innovative communication strategies that are adaptable to the dynamics of the VUCA era, thereby enhancing microinsurance penetration in Indonesia.

Abstract

This study examines the historical and cultural importance of the Talang Tuo Inscription and its potential as a heritage tourism resource in South Sumatra. Prior studies have predominantly concentrated on its philological and religious dimensions, resulting in a deficiency in comprehending its significance for cultural heritage management and sustainable tourism development. Commissioned by Dapunta Hyang Sri Jayanasa in 684 AD, the inscription encapsulates Sriwijaya’s ethical, spiritual, ecological, and humanitarian perspective, highlighting welfare, social cohesion, and equilibrium with nature. This study utilizes the historical method, incorporating heuristics, source criticism, interpretation, and historiography, and is based on inscription analysis, literature review, and field observations conducted at the Balaputera Dewa Museum. The findings indicate that the inscription served not only as an administrative record but also as a political and cultural manifesto that defined Sriwijaya’s identity as an ethical and ecological civilization. Currently, it has significant potential to advance heritage tourism through digital integration (AR/VR), site collaboration, and community-based management. This study emphasizes the need to convert the Talang Tuo Inscription into dynamic heritage, to enhance cultural diplomacy and sustainable heritage tourism, and to present a novel framework that amalgamates historical analysis with cultural tourism planning.

Abstract

This study examines the involvement of Cambodian EFL teachers in decision-making related to professional development in lower secondary schools in Phnom Penh. Using an exploratory research design, data were collected through questionnaires from 40 teachers and semi-structured interviews with six participants. The study examines how Cambodian EFL teachers perceive their role in shaping professional growth activities, including training and workshops. Findings reveal that teachers’ participation is minimal, unstructured, and largely directed by top-down decisions. Five major themes emerged: lack of professional development opportunities, limited systematic and customized involvement, inadequate professional tools, insufficient institutional support, and teachers’ discontent with their growth prospects. These issues contribute to a weak professional learning culture and a sense of exclusion. This study contributes to understanding teacher agency and professional growth in developing contexts. It emphasizes the need for systemic reform in educational policy and school leadership to foster more inclusive, collaborative, and teacher-centered professional development systems that enhance motivation, agency, and educational outcomes. Future research should include focus groups to gain deeper insights and expand across different regions and types of schools, thereby providing a more comprehensive understanding of teacher involvement in decision-making.

Abstract

The rattan industry in Cirebon, Indonesia, is a significant part of the country's creative economy, but it faces several major challenges, including unstable production, fluctuating prices for raw materials, and uncertain demand, which make it difficult to predict income. The goal of this research is to create a quantitative model that can accurately forecast business income and help entrepreneurs make better financial decisions. The study employs the Monte Carlo simulation method to examine the impact of production levels, raw material costs, and demand on the revenue of rattan businesses. The simulation was run 10,000 times using probability distributions based on historical data. The results indicate that market demand and selling prices have the most significant positive impact on profits, while raw material costs have the most substantial negative effect on profits. The model illustrates the uncertainty of business conditions, with profit varying between IDR 19.5 billion and IDR 76.1 billion, averaging IDR 50.2 billion. The findings underscore the need to strike a balance between meeting growing demand and managing costs to achieve long-term profitability. This Monte Carlo-based model can be a valuable tool for rattan business owners and policymakers to support informed planning and mitigate risks.
