Abstract

The study of Economics, particularly taxation, is often perceived as difficult because it requires an understanding of abstract concepts and technical calculation skills. Conventional teacher-centered instructional models tend to limit students' opportunities to build their own understanding actively. This study aims to examine the effectiveness of the flipped classroom (FC) model in improving student learning outcomes in Taxation. A quasi-experimental design with a non-equivalent control group pretest–posttest was used in this research. The sample consisted of 68 eleventh-grade students at XYZ Public High School in North Sulawesi, divided into an experimental group (FC) and a control group (traditional learning). Data were collected through pre-tests and post-tests and analyzed using ANCOVA, effect size, and N-Gain scores. The ANCOVA results, controlling for pretest scores, showed that the flipped classroom model led to better learning outcomes compared to traditional instruction. The FC model effectively strengthened students' cognitive abilities and practical skills through independent and collaborative learning activities. Practically, teachers need to prepare engaging digital content and contextual assignments so that the flipped classroom can serve as a relevant strategy to enhance the quality of Economics education at the senior high school level.

Abstract

The development of digital technology has driven significant changes in education and requires teachers to adapt to new learning paradigms. Teachers are expected to possess professional competencies, including pedagogical skills, content mastery, digital literacy, and readiness for technological transformation. This study aims to analyze the challenges and opportunities for developing teacher professionalism in the digital era through a literature review. The data were obtained from 35 scientific articles written in Indonesian and published in national journals, accessed through Google Scholar between 2020 and 2025. The findings indicate several challenges, such as digital literacy gaps, limited technological infrastructure, resistance to change, lack of continuous training, and high administrative workloads. However, the digital era also offers opportunities for teachers to enhance competencies through online learning platforms, digital media innovation, data-based assessment, and supportive government policies. Developing teacher professionalism requires collaboration among teachers, educational institutions, and policymakers to build an innovative and sustainable learning ecosystem. Adaptive teachers can become agents of change in achieving quality education.

Abstract

The rapid development of the technology sector in Indonesia requires companies to continuously improve their financial performance in order to remain competitive. One of the key indicators of financial performance is profitability, which is presumed to be influenced by liquidity and capital structure. The novelty of this study lies in examining the effect of liquidity and capital structure on the profitability of technology sector companies listed on the Indonesia Stock Exchange during the 2022–2024 period, a topic that has received relatively limited attention compared to other sectors.This study aims to examine the effect of liquidity (Current Ratio) and capital structure (Debt to Equity Ratio) on profitability (Return on Assets) in technology sector companies listed on the Indonesia Stock Exchange during the 2022–2024 period. This research employs a quantitative approach using panel data regression analysis. The data used are secondary data obtained from company financial statements through purposive sampling. The results indicate that liquidity has a negative but insignificant effect on profitability, while capital structure has a positive but insignificant effect. Simultaneously, liquidity and capital structure do not significantly influence profitability. These findings suggest that liquidity and capital structure are not the primary determinants of profitability in technology sector companies, indicating that other variables outside the model play a more dominant role in influencing financial performance.

Abstract

This Community Service Program (Pengabdian kepada Masyarakat/PkM) aims to enhance the capacity of Micro, Small, and Medium Enterprises (MSMEs) and Village-Owned Enterprises (BUMDes) in Wori Village, North Minahasa Regency, through the strengthening of digital marketing and product branding based on village institutional development. Wori Village has significant tourism potential, supported by coastal landscapes, mangrove forests, and flagship destinations such as Mangrove Park Ecotourism and the 3D Bridge, which provide strategic opportunities for the development of local MSMEs. However, this potential has not yet been optimally utilized through digital-based marketing strategies and systematic brand development. The program employed an integrated training and mentoring approach conducted in three stages: the preliminary stage (needs assessment and problem identification), the implementation stage (digital marketing and branding training with hands-on practice), and the evaluation stage. The approach was grounded in institutional theory, digital marketing theory, and community empowerment theory, positioning BUMDes as a key institution in coordinating and supporting collective marketing efforts among MSMEs. The results indicate a significant improvement in participants’ understanding and skills in utilizing digital media for product promotion, developing brand identity for local products, and increasing confidence in accessing wider markets. Furthermore, the program strengthened the role of BUMDes as a facilitator of community economic empowerment by integrating tourism potential with MSME development. Overall, this Community Service Program contributes to improving MSME competitiveness and fostering sustainable village economic development in the digital era. Keywords: MSMEs, BUMDes, digital marketing, branding, village tourism, community service.
