This study aims to examine the effect of green banking disclosure and social banking on firm value with banking sustainable performance as a mediating variable. The population in this research consists of banking subsector companies listed on the Indonesia Stock Exchange during the 2021–2023 period, totaling 47 companies. The sampling technique used in this study was purposive sampling, resulting in a total of 30 data points that met the research criteria and could be analyzed. The analytical method employed was path analysis using SPSS version 25 to test the relationships among variables and the mediation effect. The results of this study indicate that green banking disclosure has a positive and significant effect on firm value. Social banking also has a positive and significant effect on firm value. Banking sustainable performance has a positive and significant effect on firm value as well. However, green banking disclosure does not have a positive and significant effect on banking sustainable performance, while social banking does have a positive and significant effect on banking sustainable performance. The mediation test results using path analysis reveal that banking sustainable performance is unable to mediate the effect of green banking disclosure on firm value. Conversely, banking sustainable performance successfully mediates the effect of social banking on firm value. These findings suggest that social banking is more effective in enhancing banking sustainable performance and firm value compared to green banking disclosure.

This study analyzes performance measurement frameworks and accountability mechanisms in public service delivery through a comprehensive literature review of studies published between 2015 and 2025. Although models such as the 3E (economy, efficiency, effectiveness) and IOO (input–output–outcome) frameworks are widely used in public administration, evidence indicates that their implementation often falls short due to data limitations, bureaucratic resistance, and limited utilization of performance results in decision-making. The literature also highlights a persistent gap between theoretical performance frameworks and actual public service practices, particularly in capturing service quality and meaningful outcomes for citizens. Recent studies emphasize that citizen satisfaction and public perception are essential indicators that must be integrated into contemporary performance measurement systems. This study concludes that performance measurement and accountability are interdependent mechanisms that require strengthened organizational capacity, relevant indicators, and a culture of evidence-based improvement to enhance public service quality.

This study aims to systematically review performance measuring factors in MSMEs in the digital era in Indonesia. The research method uses Systematic Literature Review (SLR) with the design of the PRISMA framework. The data sources used were obtained from various databases of quality scientific publications including emerald, taylor and francis, springerlink, and sciencedirect, with a time span from January 2020 to June 2025. A total of 24 international scientific articles published in the period were analyzed for further identification on the main trends, main topics, and research directions. The results of the study show that the role of digital transformation has become an important factor in shaping the performance of MSMEs in the modern era. The factors that measure the performance of MSMEs are related to entrepreneurial competence, adaptation to technology, innovation ability, and government support. Some of these supporting factors also support resilience and sustainability for micro, small, and medium enterprises (MSMEs). However, the success of work achievements for business actors cannot be separated from adequate organizational readiness and resources, as well as good governance. This study contributes academically in the form of a conceptual framework for performance improvement measures for MSMEs, as well as providing recommendations as strategies for micro, small, and medium business actors to increase productivity so that businesses can grow and be sustainable in the digital era.

This study examines the inconsistency of merger and acquisition (M&A) impacts on financial ratio performance across sectors and evaluation methods. This literature review synthesizes ten empirical studies published between 2022 and 2025, focusing on financial indicators before and after M&A transactions. The findings show that the effect of M&A on financial performance varies widely depending on the industry context, time horizon, and analytical technique used. Studies in the technology and telecommunication sectors demonstrate significant improvements in profitability and operational efficiency, while research involving manufacturing and non-financial firms commonly reports insignificant changes in key ratios such as current ratio, total asset turnover, return on assets, and return on equity. Methodological differences also influence the reported outcomes, where long-term observations and comparative statistical testing tend to reveal a more pronounced financial impact compared to short-term assessment. These results indicate that M&A does not uniformly drive financial improvement and its success depends on post-integration strategy, sector dynamics, and measurement design. This study highlights the necessity of standardized evaluation frameworks to ensure more reliable performance interpretation in future M&A research.

Information system security faces serious challenges due to increasingly complex cyber attacks. Intrusion Detection Systems (IDS) require efficient approaches to handle high-dimensional data such as the NSL-KDD dataset with 41 features. This study aims to implement the Genetic Algorithm (GA) for feature selection on the NSL-KDD dataset to improve the efficiency and accuracy of network attack detection. The method used is computational experimental research, involving data preprocessing, GA implementation for feature selection, building a classification model using Random Forest, and performance evaluation based on accuracy, precision, recall, F1-score, and computation time. The results show that GA successfully reduced features from 41 to 12 features (70.7% reduction), significantly improving computational efficiency. However, model accuracy slightly decreased from 0.4973 to 0.4951, indicating that while GA is effective for feature selection, the elimination of certain features may reduce classification capability. The implication of this study is that GA can be used as a tool to simplify intrusion detection models, but it should be combined with parameter optimization and data imbalance handling to achieve more optimal performance.  

Adolescents are a vulnerable age group to nutritional problems due to increased nutritional requirements during periods of rapid growth. Suboptimal nutritional status, including undernutrition and anaemia, can negatively affect health and academic performance. This study aimed to describe the nutritional status of adolescents at SMA Negeri 2 Kendari, Southeast Sulawesi Province. This study employed a descriptive observational design conducted from August to September 2025 with a total sample of 226 twelfth-grade students’ selected using proportionate stratified random sampling. Data were collected through measurements of body weight and height to determine nutritional status based on the BMI-for-Age indicator and haemoglobin levels were assessed using a digital haemometer. Data were analyzed using univariate analysis. The results showed that most respondents had normal nutritional status (52.2%), while a considerable proportion were undernutrition (47.8%). In addition, more than half of the respondents were anaemia (50.9%). These findings indicate that although anthropometric nutritional status was generally normal, anemia remains a health problem that requires attention among adolescents. Regular monitoring of nutritional status and hemoglobin levels accompanied by nutrition education is recommended. Further studies are recommended to use an analytical study design to identify factors associated with nutritional status and anaemia.

In the context of the influence of social media on the learning concentration of Students in the learning concentration if students in the J-PBSI (Indonesia Language and Literature Education Department) at Lambung Mangkurat University, social media is one of the most influential technological products in the lives of students today. Students in J-PBSI at Lambung Mangkurat University are increasingly dependent on various digital platfroms to support their educational processes. Theses applicantions have become essential tools for socializing and sharing information with other students. The influence of social media use on the learning concentration of J-PBSI students shows that many students experience a lack of focus while studying due to the distracting effects of social media. This distraction often reduces students’ ability to contcentrate, which in turn affects their overall to concentrate, which in turn affects their overall learning performance. This study uses a descriptive qualitative method with in-depth interviem techniques conducted with several students from the Indonesia Language and Literature Education Department. The results of the most students use sosial media on a daily basis. High usage of social media tends to decrease learning concentration because students are often distracted by notifications of the urge to open social media while studying. However, there are also J-PBSI students who use social media effectively, utilizing it as an additional learning resource. Thus, the influence of social media is twofold, depending on the intensity and purpose of ir use. This study aims to determine the extent to which social media affects students’ learning concentration. It is also expected to provide a better understanding of how social media influences the learning process. Students are encouraged to use social media wisely and responsibly so that is does not interfere with their focus on studying, but instead supports their academic activities.

Furthermore, the ice bag gel system produced a steady radiation flux, indicating that it was able to minimize the effects of temperature variations. These results imply that ice bag gel PCM has the potential to be a green and economical option for enhancing thermal comfort and decrease energy consumption in buildings.

The Marketing Mix strategy is a combination of various marketing elements that include product, price, distribution place, and promotion. The Marketing Mix strategy, also known as the marketing mix is a concept in marketing that explains four main elements that must be managed in an integrated manner to achieve marketing objectives. In general practice, the using of QRIS is a payment standard using a QR code developed by Bank Indonesia and the Indonesian Payment System Association to simplify and accelerate digital transactions. Through VOSviewer analysis, the implementation of QRIS can have a positive impact on the operations and business performance of MSMEs, and the marketing mix strategy in the context of business digitalization becomes an important approach to maintaining MSME competitiveness. The results of the VOSviewer visual map analysis and the review of previous State of the Art research indicate that most existing studies still focus on aspects of QRIS adoption and transaction efficiency alone. These studies generally highlight how digital payment system is able to  improve the speed, security, and convenience of transactions but have not yet widely linked them directly to marketing mix strategies and consumer purchasing decisions. This indicates a research gap in understanding the role of QRIS is not only as a transaction tool but also as part of the marketing strategy that influences consumer behaviour.

This study aims to analyze the influence of entrepreneurship and product innovation on the marketing performance of local coffee shops in Banda Aceh City. The background of this research is based on the increasing trend of the local coffee industry which has not been accompanied by optimal marketing and innovation strategies. The research method used a descriptive-associative quantitative approach with the population of coffee shop owners and managers and a sample of 25 respondents. Data analysis was carried out by multiple linear regression using SPSS 26.0. The results of the study show that simultaneously entrepreneurship and product innovation have a significant effect on marketing performance, with an F value of 60,024 and a significance of 0,000. However, partially, only the innovation variable had a positive and significant effect on marketing performance (sig. 0.001 < 0.05), while entrepreneurship had no significant effect (sig. 0.288 > 0.05). A determination coefficient value (R²) of 0.845 indicates that 84.5% of the variation in marketing performance is explained by both variables. This study emphasizes the importance of product innovation as a dominant factor in improving the marketing performance of local coffee shops and provides implications for business owners to strengthen creativity and adaptation to consumer trends.

This literature study evaluates the accuracy of the Slope Mass Rating (SMR) method for coal mine slope stability in Indonesia through a systematic descriptive synthesis of 25 empirical studies from 2020 to 2025. The objectives of the study were to identify the level of SMR prediction accuracy, factors affecting the method's performance, and modifications required for local Indonesian conditions. The research method involved a systematic search with inclusion criteria for empirical studies reporting SMR and/or Safety Factor (SF) values ​​for coal mines and associated slopes in Indonesia. Quantitative analysis showed a range of reported SMR values ​​between 41 and 96 with a median of 72, while SF values ​​ranged from 1.137 to 4.09 for normal operational conditions. The synthesis results indicated that SMR provides a consistent stability classification for initial slope design and failure mode identification (planar, wedge, toppling), with historical validation showing a correlation of up to 91.23% between SMR-based hazard zoning and actual field events in some cases. Key limitations include dependence on discontinuity data quality, sensitivity to groundwater conditions and tropical weathering, and variation in the interpretation of adjustment factors F1-F4. Modifications such as NAAF23 and integration with numerical modeling have been shown to improve prediction reliability. It is recommended that coal mining practitioners combine SMR with kinematic analysis and limit equilibrium modeling as standard operating procedures, and develop adjustment factors specific to Indonesian geological conditions. Further research should focus on standardizing parameter reporting and cross-site quantitative validation to enable more robust statistical meta-analyses.
