The use of virtual classrooms in the learning process is a strategic step to create a flexible learning experience, accessible anytime and anywhere. Schoology's "Plasma" as a virtual classroom platform offers various digital learning features that enable students to develop Self-Regulated Learning (SRL). Through access to materials, discussions, and other digital learning resources, students are encouraged to be more active, independent, and able to plan, monitor, and evaluate their own learning process. SRL is an important internal factor that plays a role in learning success, because it encourages students to realize their learning needs without relying on direct direction from the teacher. This study is a classroom action research conducted by mathematics teachers at SMA Negeri 1 Gedongtataan, Pesawaran, Lampung, with 30 students of grade XII IPA 1 in the 2022/2023 academic year. Data were collected through questionnaires, observations, and interviews, then analyzed using descriptive statistics. The results showed that the use of Schoology's virtual classroom significantly improved students' SRL. The comparison of the average SRL scores in Cycle I and Cycle II, 2.7 and 3.2, respectively, indicates a consistent increase. This finding confirms that the integration of Schoology's virtual classroom is effective in enhancing students' learning independence at the secondary education level.

This study aims to analyze the disparity between the number of job seekers and available job vacancies in Medan City during 2023–2024, a condition that reflects a significant imbalance in the local labor market. The background of this research arises from the persistent surplus of job seekers, coupled with the sharp decline in job openings that suggests the presence of structural unemployment and a mismatch between educational qualifications and labor market needs. Using a quantitative-descriptive approach through literature review and secondary data analysis from official labor statistics, this study provides a comprehensive overview of the labor market dynamics in Medan City. The findings show that in 2023, there were 4,661 registered job seekers compared to only 2,777 available vacancies, resulting in a surplus of 1,884 individuals. The situation worsened in 2024 as job vacancies dropped drastically to 1,016 positions, while the number of job seekers reached 2,293, leaving a surplus of 1,277 individuals. The study also reveals that job seekers are predominantly senior high school graduates, accounting for approximately 80 percent of the total, while job vacancies are concentrated in the manufacturing and trade sectors—both of which experienced severe contraction in 2024. These conditions reflect multidimensional mismatches in the labor market, including vertical and horizontal mismatches, as well as a structural shift towards a service-based economy that has not fully absorbed the workforce. The implications of this study highlight the urgency of strengthening vocational training programs, aligning educational curricula with industry needs, diversifying the local economy, and enhancing job seekers’ competencies to improve competitiveness in an increasingly challenging labor market.

Poverty remains a central issue in regional development, particularly in areas with pronounced economic disparities such as South Sumatra Province. This study aims to examine the effect of Gross Regional Domestic Product (GRDP) on the poverty rate across regencies and cities in South Sumatra during the period 2020–2024. A quantitative research approach was employed using panel data regression analysis, supported by descriptive statistics and classical assumption tests. The empirical findings indicate that GRDP has a negative and statistically significant effect on poverty, suggesting that an increase in regional economic capacity contributes to reducing poverty levels. However, the relatively small coefficient signifies that economic growth has not been fully inclusive and is influenced by the structural characteristics of each region. The Fixed Effect Model was identified as the most appropriate specification, highlighting the existence of heterogeneity across districts that shapes the relationship between GRDP and poverty. These results underscore the need for development strategies that not only promote economic growth but also ensure an equitable distribution of its benefits through the reinforcement of labor-intensive sectors, enhancement of human capital, and strengthening of local economic structures. The study provides valuable insights for regional policymakers in designing more effective and sustainable poverty alleviation strategies.

This study aims to analyze the influence of entertainment content consumption on TikTok toward the stress levels of university students. TikTok has become one of the most frequently used social media platforms among young adults, offering entertainment, distraction, and emotional relief. Meanwhile, academic stress is a common issue among students due to heavy coursework, deadlines, and pressure to perform. This research uses a quantitative method with a survey distributed to 100 active university students aged 18–24 who own a TikTok account and consume entertainment content such as comedy, challenges, and viral videos. Data were analyzed using descriptive statistics and simple linear regression. The results show that the overall frequency of using TikTok for entertainment is very high (mean = 4.26), while the level of academic stress also falls into the high category (mean = 4.06). Regression analysis indicates that TikTok entertainment content significantly affects students’ stress levels (p < 0.001). Result found is positive, meaning higher TikTok usage is associated with higher stress. The significance value based on the simple linear regression coefficient table is 0.000 < 0.05, so it can be concluded that the variable Use of TikTok Entertainment Content (X) has an effect on the variable Stress Levels Among Students (Y).

This study employed a quantitative method, utilizing secondary data from 2019-2023, sourced from the Central Statistics Agency (BPS), the Ministry of Environment and Forestry (KLHK), and other sources. Panel data analysis tools, classical assumption tests, and hypothesis testing were used. Panel data regression results indicate that, partially, population density has a significant negative effect, economic growth rate has a negative and significant effect, while four-wheeled and two-wheeled motorized vehicles have a positive and significant effect on environmental quality in Indonesia. Meanwhile, collectively, population density, economic growth rate, and the number of motorized vehicles significantly influence environmental quality in Indonesia.

The economy of West Sumatra Province has shown a significant decline in recent years, with the lowest growth rate on the entire island of Sumatra. This study aims to examine the influence of capital expenditure, unemployment, and the Human Development Index on economic growth in this region between 2014 and 2024. Using multiple linear regression and data sourced from the Central Statistics Agency (BPS) and the Directorate General of Fiscal Balance, the analysis shows that capital expenditure and unemployment have a significant negative impact on economic growth, while the Human Development Index (HDI) has no significant impact. Although capital expenditure varies, the decline in unemployment indicates a change in labor market conditions. This information indicates that government efforts to increase spending on infrastructure and public services are still ineffective in driving growth. Therefore, it is recommended that the government prioritize budget allocations in productive sectors such as infrastructure, tourism, and MSME development to help small businesses grow and advance through training, capital support, and technology implementation to ensure competitiveness and sustainability. Therefore, this study is expected to provide deeper insight into the elements that influence economic growth in West Sumatra and serve as a guide for further, more comprehensive research.

Data analysis involved descriptive and inferential statistics, including simple linear regression to examine the relationship and effect of parental communication skills on children's self-confidence. The results reveal that positive, supportive communication skills characterized by democratic communication patterns have a significant positive effect on increasing children's self-confidence. Effective and empathetic communication creates a conducive environment for children to express themselves, boosting their self-esteem and social-emotional potential. The study concludes that enhancing parental communication skills is a vital strategy for family guidance and early childhood education to optimally support the development of children's self-confidence.

The rapid growth of the digital era significantly reduces children's physical activity, thus having an impact on decreasing gross and fine motor development in elementary school-age children. The habit of excessive use of gadgets causes children to tend to be passive and less involved in structured movement activities. Fundamental Movement Skills (FMS), as the basis of motor competence which includes locomotor, non-locomotor, and manipulative skills, shows increasingly less than optimal development in early childhood and school age. This study examines the contribution of FMS to children's motor development and evaluates the effectiveness of FMS-based learning media, especially modified snake and ladder games, in improving students' basic movement skills. The study used a descriptive-correlational quantitative design involving 40 students aged 6–9 years who were selected through purposive sampling techniques. Data collection was carried out using the Test of Gross Motor Development-2 (TGMD-2) instrument, structured observation rubrics, and supporting documentation. Data analysis used descriptive statistics and Pearson correlation tests to see the relationships between variables. The findings of this research are expected to be the basis for the development of more innovative, adaptive, and fun physical education programs to support children's motor development in the midst of the challenges of the digital era.

Objective: This study aimed examine the influence the social environment the mental health pregnant women Tilongka Billa Community Health Center. Methods: A quantitative correlational study was conducted with 70 pregnant women selected through purposive sampling. Data were collected using structured questionnaires assessing demographic characteristics, social support (family, peer, and community), and mental health status (Perceived Stress Scale and Edinburgh Postnatal Depression Scale). Descriptive statistics summarized the participants’ characteristics, while Pearson Spearman correlation tests analyzed relationships between social environment factors mental health outcomes (p < 0.05). Results: The results indicated that family support had the highest mean score (4.1 ± 0.7), followed by peer support (3.8 ± 0.8) and community involvement (3.5 ± 0.9). Mental health assessments revealed moderate stress levels (18.2 ± 5.0) and mild depression risk (9.5 ± 4.3). Correlation analysis showed significant negative relationships between social support and mental health indicators, with family support exhibiting the strongest correlation with reduced stress (r = -0.48, p = 0.002) and depression (r = -0.52, p = 0.001). Conclusion: The study demonstrates that supportive social environment, particularly family and peer support, plays crucial role in reducing stress and depressive symptoms among pregnant women. Strengthening social support networks through counseling, peer groups, and community engagement programs may enhance maternal mental health and promote positive pregnancy outcomes.

Family environments play a crucial role in shaping students’ learning processes, particularly at the primary education level. This study aims to examine the effect of the family environment on learning attention and the fulfillment of learning facilities and infrastructure among Grade VI students at UPT SD Negeri 1 Centre Pattallassang. Using a quantitative associative approach with an ex post facto design, data were collected from 85 students through a structured questionnaire and analyzed using descriptive statistics, simple linear regression, and canonical correlation analysis. The results indicate that the family environment has a positive and significant effect on learning attention (B = 0.631, p < 0.001) and on the fulfillment of learning facilities and infrastructure (B = 0.723, p < 0.001). The family environment explains 42.1% of the variance in learning attention and 48.6% of the variance in the fulfillment of learning facilities. Canonical correlation analysis further reveals a strong simultaneous relationship between the family environment and the combined outcomes of learning attention and learning facilities. These findings highlight the central role of the family as a key educational microsystem that supports both cognitive–affective engagement and material learning conditions. The study underscores the importance of strengthening school–family collaboration and family-based support strategies to enhance learning quality in primary education.  

This study aims to analyze the transformation of the educational pattern at the Indonesian Naval Academy (AAL) from a four-year to a three-year system and its impact on graduate competencies and operational readiness. This educational system change responds to budget efficiency needs and accelerated officer formation filling, yet raises questions about the new system's ability to maintain the quality of officer education. The research employs a mixed methods approach with a concurrent embedded design, involving 250 respondents comprising graduates from both educational systems, AAL instructors, and unit commanders receiving graduates. Quantitative data were collected through structured questionnaires and analyzed using descriptive and inferential statistics (independent sample t-test and regression), while qualitative data were obtained through in-depth interviews, observations, and document studies analyzed using thematic analysis. Results indicate no significant difference in overall Grade Point Average (GPA) between the two groups (p=0.470), but significant differences in competency patterns emerged: four-year system graduates excelled in theoretical competencies (p=0.001), while three-year system graduates excelled in practical competencies (p=0.003). Operational readiness evaluation shows that four-year system graduates obtained higher scores (82.5) compared to three-year system graduates (78.3), with significant differences (p=0.012), particularly in strategic leadership and complex decision-making aspects. Qualitative analysis identified five major themes: high learning time pressure, orientation shift from comprehensive to pragmatic, gaps in character formation and corps values, concerns about theoretical understanding depth, and need for more intensive post-graduation mentoring programs. This study concludes that educational time compression successfully increased operational efficiency but involved trade-offs in learning depth and professional maturity. To optimize the three-year educational system, a comprehensive approach is required, including curriculum revision with integrated learning methods, utilization of modern learning technology, strengthening of leadership development programs, and development of continuous professional mentoring systems. The recommendations of this research are expected to provide input for AAL and the Indonesian Navy in refining the officer education system to produce officers who are not only technically competent but also mature in leadership and strong in character.

Micro, Small, and Medium Enterprises (MSMEs) play a vital role in Indonesia’s economic growth by creating employment opportunities and contributing significantly to the national GDP. However, their contribution to the country’s tax revenue remains relatively low compared to their overall economic impact. This study aims to examine the contribution of the MSME sector to Indonesia’s tax revenue and to identify the factors influencing this contribution level. The research employs a descriptive quantitative approach using secondary data from Statistics Indonesia (BPS), the Directorate General of Taxes (DGT), and the Ministry of Finance covering the period 2018–2023. The findings indicate that the tax contribution from MSMEs has gradually increased over the years, although it still accounts for less than one percent of total national tax revenue. This positive trend is supported by the implementation of lower tax rates, the digitalization of tax systems, and the growing tax awareness among business owners. The study suggests that further administrative simplification and stronger government support are essential to enhance the role of MSMEs in strengthening Indonesia’s fiscal capacity

Inflation, unemployment, and deflation are three fundamental macroeconomic phenomena that are closely interconnected in influencing a nation’s economic stability. These variables illustrate the equilibrium between production capacity, consumption behavior, and government intervention in achieving sustainable economic growth. The main purpose of this study is to explore the interrelationship between inflation, unemployment, and deflation, and to assess their implications for Indonesia’s economic stability. This research applies a qualitative descriptive method, employing literature reviews, document analysis, and secondary data evaluation derived from credible institutions such as the Central Bureau of Statistics (BPS), Bank Indonesia (BI), and the Ministry of Finance. The results suggest that a moderate level of inflation can positively stimulate economic expansion through increased consumption and investment activities. In contrast, excessive inflation tends to erode consumer purchasing power and potentially elevate unemployment rates. Meanwhile, prolonged deflationary conditions may lead to a decline in product prices, reduced business profitability, and slower economic momentum. The interaction among these three factors is complex and dynamic, necessitating a coordinated balance between fiscal and monetary policies to safeguard overall economic stability. This study concludes that effective inflation control, job creation, and deflation prevention are critical elements in strengthening Indonesia’s long-term economic resilience.

The Chi-square check received a p-cost of 0.000 (<zero.05) with a Chi-square fee of 30.410, indicating a massive relationship between dietary knowledge and CED. Pregnant ladies with top dietary understanding were much less in all likelihood to enjoy CED, even as all respondents with terrible information skilled CED. end: there's a large courting between dietary understanding and the incidence of CED amongst pregnant girls. continuous dietary training is vital to lessen the risk of CED and enhance maternal fitness.

The Jakarta Composite Index (JCI), also known as the Indonesia Composite Index is a key indicator that reflects the performance of the Indonesian capital market and serves as a reference for assessing economic conditions and making investment decisions. This study aims to examine the influence of macroeconomic factors such as inflation, the rupiah exchange rate, and interest rates along with an external factor, the Dow Jones Index, on the JCI during the period 2020–2024. This research contributes by incorporating the DJIA as a proxy for global market effects on the JCI and by using the most recent and comprehensive dataset covering the pandemic and subsequent economic recovery. A quantitative approach was employed, using monthly time-series secondary data. The study applied saturated sampling, resulting in 60 observations. The data were obtained from official sources, namely the Indonesia Stock Exchange (IDX), Bank Indonesia (BI), the Central Statistics Agency (BPS), and Investing.com. Multiple linear regression was used as the analysis technique. The results show that inflation and the Dow Jones Index have a significant positive effect with the JCI, while the rupiah exchange rate has a significant negative effect. In contrast, interest rates do not show a significant effect on the JCI. These findings suggest that investors should consider inflation, the exchange rate, and global market movements (DJIA) when making investment decisions, while interest rates may play a less prominent role.
