This study compared the performance of SARIMA and Prophet models in forecasting daily close prices of three major Indonesian banking stocks: BBCA, BBRI, and BMRI, using data from January 2020 to March 2026. Data were retrieved via the yfinance library, preprocessed, and split into 80% training and 20% testing sets. SARIMA modeling followed the Box-Jenkins procedure, while Prophet was configured with a Lag-1 regressor, weekly and monthly seasonality, Indonesian public holidays, and log transformation. Model performance was evaluated using MAPE, MSE, and Dstat metrics. Results showed that SARIMA outperformed Prophet in MAPE and MSE across all six stock-variable combinations, with MAPE values ranging from 1.3368% to 1.9386% for SARIMA and 1.5992% to 2.2300% for Prophet. However, Prophet demonstrated marginally higher Dstat values in several series. Both models achieved "Very Good" forecasting accuracy. A web-based forecasting system was also developed using Streamlit to make the models accessible to investors.

Earnings management remains a major concern in the banking industry because it may reduce the credibility and reliability of financial reporting. At the same time, Corporate Social Responsibility (CSR) has increasingly been recognized as an important governance mechanism that enhances corporate transparency, accountability, and stakeholder trust. However, previous studies have reported inconsistent findings regarding the role of firm size in the relationship between CSR and earnings management. Therefore, this study aims to examine the effect of CSR on earnings management and investigate whether firm size acts as a mediating variable in Indonesian banking companies. This research employed a quantitative explanatory approach using panel data from 22 banking companies listed on the Indonesia Stock Exchange during the 2022–2024 period, resulting in 66 observations. Data were analyzed using panel data regression with the Fixed Effect Model and mediation analysis through the Sobel test using EViews 12. The findings indicate that CSR has a significant negative effect on earnings management and a significant positive effect on firm size. Furthermore, firm size partially mediates the relationship between CSR and earnings management, indicating that CSR reduces earnings management both directly and indirectly through organizational scale. These findings provide theoretical support for stakeholder and legitimacy theories and offer practical insights for managers and regulators in strengthening CSR implementation to improve financial reporting quality and corporate transparency.

Bilingual instruction is a learning strategy that can help students understand learning materials while bridging the gap between the language used at school and the language spoken in daily life. This study aims to analyze the effect of bilingual instruction on students' understanding of the Ecosystem topic at SDK Gusung Karang, Koja Gete Village. The study was motivated by the fact that students predominantly use the Sikka language in their daily communication, making it difficult for them to understand lessons delivered solely in Indonesian. This study employed a qualitative approach with a descriptive method. The research participants consisted of the fourth-grade homeroom teacher and fourth-grade students at SDK Gusung Karang. Data were collected through observations, interviews, and documentation and analyzed using data reduction, data display, and conclusion drawing techniques. The findings indicate that bilingual instruction has a positive impact on students' understanding of the Ecosystem topic. The use of the Sikka language helps students comprehend basic concepts, increases classroom participation, and enhances their confidence during the learning process. Meanwhile, Indonesian strengthens students' mastery of scientific terminology and academic language skills. Although students still experience difficulties in consistently using scientific terms in Indonesian, bilingual instruction improves their understanding and connects learning concepts with their real-life experiences. The effectiveness of this strategy depends on teachers' ability to manage language switching in a structured and consistent manner.

The increasing emphasis on sustainable business practices has encouraged companies to integrate environmental and social responsibilities into their strategic and financial decision-making processes. This study investigates the influence of Green Accounting on Firm Value and examines the moderating role of Corporate Social Responsibility (CSR) within the Triple Bottom Line framework. A quantitative research design was employed using panel data from 23 energy, mining, and infrastructure companies listed on the Indonesia Stock Exchange during the 2022–2024 period, resulting in 69 firm-year observations. Secondary data were collected from annual reports and sustainability reports and analyzed using descriptive statistics, classical assumption tests, and Moderated Regression Analysis (MRA). The findings indicate that Green Accounting does not have a significant direct effect on Firm Value, while CSR also shows no significant direct influence. Furthermore, CSR is unable to significantly moderate the relationship between Green Accounting and Firm Value. These results suggest that sustainability initiatives implemented by Indonesian companies have not yet generated measurable short-term financial benefits, although they may contribute to long-term corporate legitimacy, stakeholder trust, and sustainable competitiveness. The study provides practical implications for corporate managers, investors, and policymakers by emphasizing the importance of strengthening sustainability reporting quality and integrating environmental and social strategies into long-term corporate value creation.

This study investigates the relationship between green practices and corporate tax avoidance, focusing on green accounting, environmental performance, and corporate social responsibility (CSR) among 19 Indonesian publicly listed companies from 2021 to 2024. The research aims to examine whether environmentally responsible strategies influence firms’ tax behavior and how sustainability practices mediate this relationship. A quantitative approach was employed, collecting data from corporate financial statements, ESG reports, and sustainability disclosures. The analysis included descriptive statistics, correlation tests, and pooled ordinary least squares regression to explore the effects of green accounting, environmental performance, and CSR on the effective tax rate (ETR) as a proxy for tax avoidance. Results indicate that green accounting is positively associated with higher ETR, suggesting reduced tax avoidance, while CSR negatively impacts ETR, implying that sustainability initiatives can be strategically used to mask aggressive tax planning. Environmental performance alone does not significantly affect tax behavior. These findings highlight the importance of transparency through green accounting to promote ethical tax practices, while cautioning that CSR may serve as a reputational tool rather than a mechanism for reducing tax avoidance. The study contributes to theoretical understanding in sustainability and corporate governance and offers practical insights for policymakers and corporate managers to align environmental and fiscal responsibilities.

The development of digital financial technology has accelerated the transition from cash-based to cashless payment systems across various economic sectors, including traditional markets. One of the most widely adopted innovations is the Quick Response Code Indonesian Standard (QRIS), which offers convenience, speed, and security in financial transactions. This study aims to analyze the role of digital financial literacy in supporting the utilization of QRIS and its implications for the profitability and business sustainability of traditional market traders in Surabaya. The study employed a descriptive qualitative approach, with data collected through observation and documentation of traders' transaction activities. The findings indicate that the utilization of QRIS among traditional market traders remains suboptimal. This condition is influenced by limited digital financial literacy, insufficient technological skills, and the readiness of business owners to adopt digital payment systems. In addition, concerns regarding transaction security and limited technological competence, particularly among elderly traders, remain significant barriers to digital transformation. Nevertheless, digital financial literacy has been shown to improve transaction efficiency, facilitate financial record-keeping, reduce transaction errors, and support more effective business management. Therefore, strengthening digital financial literacy is a strategic factor in optimizing QRIS adoption to enhance profitability and ensure the long-term sustainability of traditional market businesses in the digital economy.

This study examines the emergence of localized English expressions in Indonesian social media discourse, highlighting how English is adapted and reinterpreted in multilingual digital contexts. While previous studies on English in Indonesia have primarily focused on formal domains such as education and language policy, limited attention has been given to informal online communication where linguistic innovation is highly visible. This study aims to analyze how English lexical items are re-semanticized and creatively transformed by Indonesian users on social media platforms. The study employed a qualitative approach using data collected from Instagram posts and comments, focusing on selected examples of English-derived expressions such as boba, gas, voucher, server, and suamiable. The analysis compares the conventional meanings of these terms in Inner Circle English with their localized meanings in Indonesian usage. The findings reveal that English functions as a flexible linguistic resource, undergoing processes of semantic shift, metaphorical extension, and lexical blending. These localized forms reflect users’ creativity as well as their ability to adapt global linguistic resources to local cultural contexts. The study concludes that English in Indonesian social media is not merely borrowed but actively reconstructed, contributing to the dynamic development of English in the Expanding Circle.

Language errors in public spaces are still frequently found in various media, such as signboards, banners, billboards, and posters. This phenomenon not only indicates a deviation from standard Indonesian language rules but also has the potential to influence how people understand and use language. This study aims to describe the forms of language errors in public spaces, analyze them from a critical linguistic perspective, and identify their implications for public literacy. The method used is descriptive qualitative research with a critical linguistic analysis approach. Data in the form of examples of language use in public spaces are analyzed based on aspects of spelling, diction, and sentence structure, then interpreted in relation to the social practices and ideologies that underlie them. The results of the study indicate that the dominant language errors include spelling errors, inappropriate word choice, and the use of ineffective sentence structures. From a critical linguistic perspective, these errors are not only caused by a lack of mastery of language rules but are also influenced by social habits, the reproduction of deviant language practices, and the tendency to use foreign languages ​​to construct a certain image. These findings indicate that repeated exposure to language that does not conform to rules can affect the quality of public literacy. Therefore, it is necessary to strengthen critical literacy and increase language awareness so that society is able to use and evaluate language more appropriately and responsibly.

A qualitative descriptive method with a literary analysis approach was employed. The data consist of dialogues, scenes, and conflicts in the film, collected through observation and documentation techniques. The findings reveal eighteen data of social values and twelve data of moral values, reflected through character interactions and ethical choices. These values are relevant for developing conflicts, characters, and messages in drama texts. This study concludes that Jumbo can serve as an effective and meaningful teaching material to enhance students’ drama writing skills and support character education.

This article examines the relationship between Islam and the local traditions of the Minangkabau community in West Sumatra, Indonesia. The focus covers three main issues: the historical process of Islamization, the philosophy of Adat Basandi Syarak, Syarak Basandi Kitabullah (ABS-SBK), and the coexistence of the matrilineal kinship system with Islamic inheritance law. Using a qualitative approach through systematic literature review of peer-reviewed journals published between 2020 and 2025, the study synthesizes findings from multiple academic sources. The results reveal that Islam entered Minangkabau gradually through trade and the surau educational institution, rather than through forced conversion. The resulting ABS-SBK philosophy meaning customary law is grounded in Islamic law, which is grounded in the Quran serves as a comprehensive life guide integrating religious norms with adat practices. The matrilineal inheritance system (pusaka tinggi) coexists with Islamic inheritance law (faraid) through a functional distinction: communal ancestral property follows adat, while individually acquired property follows Islamic law. Contemporary challenges such as globalization, urbanization, and weakened institutional roles of adat leaders threaten the vitality of ABS-SBK, though cultural revitalization efforts show promising resilience. This study concludes that Minangkabau represents a unique model of Islam-culture integration in the Indonesian archipelago.

This study aims to describe the utilization of multimodal media in teaching news text reading skills among seventh-grade junior high school students. The research employed a quantitative approach with a descriptive research design. The data were collected through questionnaires distributed to 61 seventh-grade students as the research respondents. The research instrument used a Likert scale covering aspects of students’ perceptions, comprehension, motivation, participation, and readiness toward the use of multimodal media in learning news text reading skills. The data were analyzed using descriptive quantitative techniques through percentage calculations and interpretation of respondents’ answers. The findings revealed that most students showed positive responses toward the use of multimodal media. A total of 72.1% of students agreed that learning through printed and digital media made the learning process more engaging. In addition, 59% of students stated that digital media helped them understand news content more clearly, while 60.7% felt more active during learning activities using multimodal media. The use of multimodal media also increased students’ motivation, self-confidence, and reading comprehension skills in understanding news texts. The findings indicate that the combination of printed and digital media creates a more interactive and effective learning environment that aligns with students’ literacy needs in the digital era. Therefore, multimodal media can serve as an alternative instructional strategy to improve students’ news text reading skills in junior high schools. The implications of this study highlight the importance of integrating digital and printed media in Indonesian language learning to enhance students’ reading literacy quality.

Background: Non-communicable diseases (NCDs) are a leading cause of morbidity and mortality worldwide and pose a significant public health challenge in Indonesia. Indonesian Army (TNI AD) personnel are at risk of developing NCDs due to operational stress, smoking habits, unhealthy dietary patterns, sleep disturbances, and insufficient physical activity outside working hours. Health education is an effective health promotion strategy to improve awareness and encourage healthy lifestyle behaviors for NCD prevention. This community service program aimed to improve the knowledge of Indonesian Army personnel regarding the prevention of non-communicable diseases through health education. Methods: The program was conducted at the 18/YKR Combat Engineer Battalion, Gianyar, Bali, in August 2024 and involved 40 Indonesian Army personnel. The intervention consisted of preparation, health education delivered through lectures and interactive discussions, and evaluation using pre-test and post-test questionnaires to assess participants' knowledge before and after the educational session. Results: Before the intervention, 29 participants (72.5%) had fair knowledge and 11 (27.5%) had good knowledge regarding NCD prevention. Following the health education session, the number of participants with good knowledge increased to 14 (35.0%), while those with fair knowledge decreased to 26 (65.0%). Most participants also demonstrated improved post-test scores, indicating enhanced understanding of NCD risk factors and preventive measures. Conclusion: Health education effectively improved participants' knowledge regarding NCD prevention. Regular and sustainable educational programs in military settings are recommended to strengthen awareness, promote healthy lifestyle practices, and support the prevention of non-communicable diseases among Indonesian Army personnel.

This study examines the effectiveness of the GOOL (Dukcapil Go Online) service in accelerating the issuance of birth certificates at the Population and Civil Registration Office of Probolinggo City. GOOL is a digital-based civil administration service innovation that allows residents to process civil documents without visiting the office in person. This study employed a descriptive qualitative method, with data collected through in-depth interviews, observation, and documentation. Effectiveness indicators were based on Campbell's (2014) theory, covering: program success, goal achievement, community satisfaction, and overall objective attainment. The findings indicate that the GOOL service is generally effective in expediting birth certificate issuance. Supporting factors include collaboration with healthcare facilities (Indonesian Midwives Association and hospitals), an integrated 3-in-1 service program, and adequate technological infrastructure. Inhibiting factors include technical difficulties during document uploads, unstable internet connections, and limited digital literacy among some residents.

This study investigates why applicants who have passed the initial admissions stage do not proceed to final enrolment in an Indonesian private higher education context. While student recruitment is often measured by the number of applications received, institutional sustainability depends on the ability to convert applicants into enrolled students. This study employed a descriptive survey design supported by thematic analysis of open-ended responses. Data were collected from 179 applicants who had participated in the admissions process but did not complete final re-registration. The data were analyzed using frequencies, percentages, and thematic categorization. The findings show that conversion failure is influenced by several factors, including waiting for public university admission results, financial constraints, postponement of study plans, family considerations, uncertainty about the institution or study programmed, preference for other institutions, and campus accessibility. A key finding reveals that 58.1% of respondents would reconsider enrolment if scholarships, tuition discounts, or other financial assistance were available. These findings highlight the need for a conversion management strategy through targeted financial aid, transparent cost communication, family engagement, and proactive applicant follow-up.  

This study aims to examine the cyber policies implemented by the Indonesian government in light of the impact of digital technology developments on the younger generation, with a view toward achieving inclusive and youth-friendly governance.

The research was conducted in three stages: data collection, data analysis, and presentation of results. The data source for this study is Law No. 1 of 2024. The data consists of structured documents collected using the read, observe, and record technique. The results indicate that the cyber policies in Law No. 1 of 2024 mark a shift from a reactive to a proactive approach by prioritizing child protection. This policy expands the scope of protection to include personal data, privacy, and child safety in the digital space, while also affirming the responsibilities of Electronic System Operators. The research findings are expected to enrich understanding of the importance of a policy communication model that is creative, transparent, participatory, and responsive in fostering literacy and critical awareness regarding the use of information technology. Thus, this research is expected to contribute to supporting the realization of a more inclusive digital space governance that is youth-friendly and aligned with the strengthening of moral values and social ethics in community life.  

The community service activities aim to improve business financial management skills and student readiness in facing the 2026 Indonesian Student Innovation and Entrepreneurship Festival (FIKSI). The program is implemented by lecturers of the Digital Business Study Program at Al-Irsyad University Cilacap together with supervising teachers and 26 FIKSI finalist students from SMA Negeri 2 Cilacap, SMA Negeri 3 Cilacap, and SMA Negeri 1 Maos. The main problem faced by partners is the low ability to prepare business financial reports and the use of digital technology in business development. The method used is Participatory Action Research (PAR) through stages of socialization, training, technology implementation, mentoring, evaluation, and program sustainability. The results of the activity show an increase in student understanding and skills in recording transactions, calculating the cost of production, preparing profit and loss and cash flow reports, and utilizing digital financial applications and Artificial Intelligence (AI) to support business development. In addition, supervising teachers received capacity building in assisting students in aspects of financial management and preparing business proposals. The establishment of the Smart Fintech Young Entrepreneur Community is a sustainable strategy for the program to support the development of digital entrepreneurship in schools. This program has proven effective in improving the quality of business and improving students' readiness for entrepreneurship competitions.

The development of stand-up comedy as part of the creative industry raises legal issues regarding the protection of materials that are often duplicated and distributed without authorization. This study examines the legal qualification of stand-up comedy material as a copyrighted work and the form and scope of copyright protection provided under Indonesian law. This research aims to analyze the legal status of stand-up comedy material and the protection granted to it. The method used is normative juridical research with statutory and comparative law approaches. The results show that stand-up comedy material fulfills the requirements of a protected work as it contains originality and has been expressed in a tangible form. It is classified as a literary work in the form of oral expression as well as a performing art under Law Number 28 of 2014 on Copyright. The protection covers both moral rights and economic rights; however, its implementation remains weak, especially in the digital era where violations such as re-uploading and unauthorized recording are prevalent. In conclusion, stand-up comedy material has a strong legal basis for protection, but further efforts are needed in law enforcement and public awareness to ensure effective protection.

This study aims to evaluate the level of sharia compliance in musyarakah contracts within micro-enterprise financing. Musyarakah is a partnership-based financing contract that emphasizes cooperation, profit-sharing based on an agreed ratio (nisbah), and proportional risk sharing in accordance with each party’s capital contribution. In practice, the implementation of musyarakah contracts in micro-enterprise financing must be assessed against the Fatwa of the National Sharia Council–Indonesian Ulema Council (DSN-MUI), principles of fiqh muamalah, and Islamic banking regulatory frameworks in Indonesia. The findings show that the implementation of musyarakah working capital financing in Islamic banking is generally in the good category. However, two non-compliance issues with sharia principles were identified. First, there is an imbalance in work participation, where the business is fully managed by the customer while the bank only provides supervision and guidance without active involvement, whereas active participation of partners is a fundamental principle of musyarakah. Second, there is an element of riba due to the use of a fixed profit-sharing scheme, even though profits in musyarakah should be uncertain and based on actual business performance. The study implies that Islamic banks need to improve musyarakah implementation to ensure full compliance with DSN-MUI fatwas, particularly in terms of active bank participation and non-fixed profit-sharing arrangements. Properly implemented, musyarakah financing can strengthen micro and small enterprises by promoting justice-based and risk-sharing economic cooperation.

This literature review analyzes the impact of data privacy issues on consumer usage intention in Indonesian e-commerce platforms. The study aims to map privacy threats and understand the phenomenon of the privacy paradox in the context of digital retail. Using a literature review method, this study synthesized findings from international journals published in the last five years from Scopus, Web of Science, and Google Scholar databases. The results show that excessive data collection, unauthorized secondary use, and data breaches significantly increase consumer privacy concerns. However, the research also confirms a privacy paradox, where consumers willingly share personal data to gain shopping convenience and promotions. The findings highlight that strong brand trust and a seamless user experience can effectively mitigate these privacy fears. Practically, this study recommends that e-commerce companies implement the Privacy by Design framework, utilize dynamic passwords (OTP), and provide transparent privacy settings as a competitive marketing advantage. Future research should explore specific regional demographics and the direct impact of new technologies like AI chatbots on consumer security perceptions.

This study aimed to develop teaching materials based on Problem Based Learning (PBL) assisted by Canva media for teaching biography writing to tenth-grade vocational high school students and to examine their validity, practicality, and effectiveness. The study employed a Research and Development (R&D) method using the ADDIE model, which consists of five stages: analysis, design, development, implementation, and evaluation. The participants were 30 tenth-grade vocational high school students. Data were collected through observation, interviews, expert validation questionnaires, student response questionnaires, biography-writing tests, and documentation. The data were analyzed using descriptive quantitative and qualitative techniques. The results revealed that the developed teaching materials achieved a validity score of 95%, categorized as highly valid based on evaluations by subject-matter and media experts. The practicality level reached 94%, categorized as highly practical according to students’ responses. Furthermore, the effectiveness test demonstrated an improvement in students’ biography-writing skills, as indicated by the increase in the average score from 63.47 in the pretest to 84.73 in the posttest. The Normalized Gain (N-Gain) score of 0.58 was categorized as moderate. These findings indicate that the Canva-assisted PBL teaching materials are valid, practical, and effective for use in biography-writing instruction for vocational high school students. The study contributes to innovations in Indonesian language teaching by integrating problem-based learning with digital technology to enhance students’ writing skills.
