This study aims to analyze the influence of inflation and interest rates on banking profitability as measured through Return on Assets (ROA) in conventional banks listed on the Indonesia Stock Exchange (IDX) during the 2020–2024 period. The research was conducted from April to May 2025 with a quantitative approach and multiple linear regression analysis methods. The data used are secondary data obtained from the annual financial statements of eight conventional banks as well as macroeconomic data from Bank Indonesia, which were selected through the purposive sampling method. The data analysis process includes descriptive statistics, classical assumption test, t test, F test, and determination coefficient. The results of the study show that partially, neither inflation nor interest rates have a significant effect on ROA. This is shown by the value of t calculating inflation of 0.049 < t table 2.02619 with a significance of 0.961 > 0.05, and t calculating interest rates of 1.163 < t table 2.02619 with a significance of 0.252 > 0.05. However, simultaneously, inflation and interest rates have a significant effect on ROA, as shown by the calculated F value of 8.698 > F table 3.25 and the significance of 0.001 < 0.05. These findings indicate that although individual macroeconomic variables do not have a significant impact, together they have an influence on banking profitability. This research contributes to policy makers and banking industry players in understanding macroeconomic dynamics on banks' financial performance.

This study aims to analyze the effect of intellectual capital and profitability on firm value in manufacturing companies in the food and beverage sub-sector listed on the Indonesia Stock Exchange (IDX) during the 2020-2023 period. Intellectual capital is measured using the Value Added Intellectual Coefficient (VAIC) method, which consists of three components: Value Added Capital Employed (VACA), Value Added Human Capital (VAHU), and Structural Capital Value Added (STVA). Meanwhile, profitability is proxied by Return on Assets (ROA). This study uses a quantitative approach with purposive sampling, resulting in 59 companies as research samples. After data screening and the removal of outliers, the number of observations analyzed was 138. The data were analyzed using multiple linear regression with SPSS software. The results of the study show that intellectual capital does not have a significant effect on firm value. This finding indicates that the management and disclosure of intellectual assets in food and beverage companies have not been able to improve investors' perception of the company’s market value. On the other hand, profitability has a positive and significant effect on firm value. This means that the higher the profitability, the higher the firm value, as reflected in investor confidence. This study emphasizes that conventional financial indicators remain the main focus of investors, while the role of intellectual capital has not yet been fully considered as a strategic resource that can directly enhance firm value.

Numeracy is an important skill that elementary school students must have, but in reality it is still relatively low because learning tends to be conventional and less contextual. Numeracy does not only include the ability to count, but also the ability to understand, use, and interpret numbers and data in various daily life contexts. One of the causes of low student numeracy is a learning approach that is less interesting and not related to real situations. This study aims to test the effectiveness of the contextual learning model (Contextual Teaching and Learning/CTL) in improving students' mathematical numeracy skills. The research design used was a one-group pretest-posttest experiment with 23 fifth-grade students of SDN 002 Teluk Bintan as subjects. The instrument in the form of a numeracy test was given before and after the implementation of CTL, then the data were analyzed using prerequisite tests (normality and homogeneity) followed by a paired sample t-test. The results showed a significant increase in students' numeracy skills. The average pretest score of 24.78 increased to 73.91 in the posttest with a significance value of 0.000 <0.05. This increase proves that CTL is effective in helping students master numeracy through a learning process that links mathematical concepts with real experiences. Thus, the contextual learning model can be an alternative learning strategy that is relevant for increasing elementary school students' numeracy, while emphasizing the importance of implementing a more applicable approach in mathematics learning.

This research presents a phenomenological inquiry aimed at deconstructing the conventional marketing paradigm and offering a deeper understanding of alternative practices. It specifically explores the anti-marketing strategy grounded in Islamic values as implemented at Warung Jendil Mbah Yamah, a traditional micro, small, and medium enterprise (MSME) located in Blitar, East Java. Employing a qualitative approach combined with a phenomenological method, the study gathered rich and nuanced data through several techniques, including in-depth interviews with nine carefully selected informants, participatory observation over an extended period, and systematic documentation studies. The thematic data analysis conducted by the researchers revealed that the warung’s anti-marketing strategy rests firmly on three interconnected pillars: (1) a strong reliance on organic word-of-mouth  communication rather than paid advertising, (2) the deliberate creation of an authentic, personal, and inclusive customer experience that builds emotional bonds with visitors, and (3) the consistent integration of Islamic ethical values into every aspect of business operations. These findings provide a meaningful theoretical contribution by synthesizing the concepts of anti-marketing and Islamic entrepreneurship into a new model of “authentic marketing,” where ethical and spiritual values serve as the strategic foundation for long-term sustainability. In practical terms, the results offer guidance for the broader development of MSMEs in Indonesia, showing that authenticity, ethical commitment, and adherence to core values can represent a stronger and more sustainable competitive advantage than conventional promotional strategies.

Enhanced Recovery After Surgery (ERAS) is a multidisciplinary, evidence-based perioperative care approach designed to minimize the stress response to surgery, preserve organ function, and improve clinical outcomes. A substantial body of evidence has demonstrated that implementing ERAS protocols in elective procedures not only accelerates patient recovery but also reduces healthcare costs. Surgery, one of the most commonly performed medical interventions worldwide particularly major procedures such as abdominal and colorectal surgery carries a high risk of postoperative complications. These complications contribute to increased morbidity, mortality, and economic burden for both patients and healthcare systems. This situation presents a particular challenge in the era of universal health coverage, which demands efficiency in terms of time, cost, and resource utilization. ERAS implementation has been proven to enhance postoperative recovery, shorten hospital stays, and expedite the return of normal physiological function compared to conventional surgical care, especially in lower abdominal surgeries and colorectal resections. A literature review was conducted by searching relevant articles through Google Scholar using inclusion criteria such as publications from 2018 onwards, focused on ERAS in abdominal surgery, full-text availability, and academic journal sources. The data were analyzed using a matrix table comparing research methods, study populations, research locations, and reported outcomes. ERAS protocols have shown to be effective in abdominal surgical procedures for improving patient recovery and reducing postoperative complications.

Conventional robotic surgical systems, while offering enhanced dexterity and 3D visualization, suffer from a critical limitation: the absence of tactile sensation. This sensory disconnect can lead to inadvertent tissue damage from excessive force application and complicates delicate maneuvers that rely on the surgeon's sense of touch. This research proposes and validates a novel surgical robotic system architecture designed to bridge this sensory gap by integrating high-fidelity 3D visual input with accurate, real-time force feedback from tactile sensors mounted on the end-effector. To rigorously evaluate this innovation, a structured comparative methodology was employed. A cohort of surgeons performed standardized surgical tasks, including suturing and tissue manipulation, on realistic soft-tissue phantoms. The performance of a conventional (visual-only) system was benchmarked against that of the proposed (visual-haptic) system. A comprehensive dataset was collected, which included objective metrics such as task completion time, precision deviation from the ideal tool path, and the magnitude of applied forces. Concurrently, subjective evaluations from the participating surgeons were gathered to assess perceived control, cognitive workload, and overall task confidence. The test data revealed statistically significant improvements when using the visual-haptic system. Participants not only completed tasks with greater speed and accuracy but also applied considerably lower and more consistent forces. The analysis underscores that haptic feedback, enabled by advanced sensor fusion, not only restores a crucial 'sense of touch' to the surgeon but also reduces the incidence of excessive force application, potentially minimizing tissue trauma and improving patient recovery. These findings confirm the hypothesis that haptic-visual integration constitutes a new paradigm in robotic surgery, shifting the paradigm from purely visual guidance to a more intuitive, multi-sensory surgical experience. This study also discusses future challenges and opportunities, including the potential for AI-driven partial autonomy, such as creating virtual safety boundaries or automating sub-tasks, and the development of next-generation sensor technologies to further enhance clinical outcomes.
