Regular physical activity is known to play an important role in maintaining overall health, including improving immune system function and mental health. Lack of physical activity remains a public health issue, making it important to understand the impact of physical activity on the immune system and mental health. This study aimed to review the effect of regular physical activity on the immune system and mental health using a literature review method. The literature sources were obtained from publications within the last five years using databases such as Google Scholar, PubMed, and ScienceDirect. The articles were then screened and selected based on inclusion and exclusion criteria, resulting in nine relevant articles for analysis. The selection results indicate that regular physical activity can increase the mobilization and activity of immune cells such as lymphocytes, neutrophils, and natural killer cells, and also modify the adaptive immune system through changes in T cells and B cells. In addition, physical activity also improves mental health through neurobiological mechanisms such as increased endorphin, dopamine, and serotonin levels, which can reduce stress, anxiety, and depression, as well as improve sleep quality and psychological well-being. Therefore, regular physical activity has a positive effect on the immune system and mental health and can be used as a promotive and preventive strategy to maintain overall health.

English learning at the elementary school level plays an important role in developing students’ early language competence, particularly in listening skills as the foundation for other language abilities. However, many learning processes still rely on conventional teaching methods that do not fully accommodate the developmental characteristics of young learners, resulting in limited engagement and listening comprehension. Therefore, this study aims to analyze the role of storytelling in improving English listening skills among elementary school students and to identify effective implementation strategies in classroom learning. This research employs a library research method by reviewing and analyzing various relevant literature sources, including books, scientific journals, and previous research findings related to storytelling in English language learning. The analysis shows that storytelling contributes significantly to improving students’ listening comprehension, vocabulary acquisition, attention, and learning motivation. Through structured narratives, expressive delivery, and the support of visual media, storytelling creates a contextual and meaningful learning environment that helps students understand spoken English more effectively. The findings also indicate that the effectiveness of storytelling is closely related to the developmental characteristics of elementary school students who learn better through concrete, imaginative, and engaging experiences. Furthermore, the implementation of storytelling through systematic stages pre-listening, while-listening, and post-listening can enhance students participation and comprehension during the learning process. In conclusion, storytelling can be considered an effective instructional strategy for improving English listening skills among elementary school students while also supporting vocabulary development and creating an engaging learning atmosphere.

Early Childhood Education (PAUD) or Kindergarten (TK) is an important level of education in building the foundations for children's overall development, covering aspects of religious and moral values, physical-motor skills, cognitive skills, language, social-emotional skills, and the arts. The development of PAUD/TK currently shows a positive trend, as seen in the increasing public awareness, number of institutions, and participation of children aged 4–6 years. However, challenges still arise, such as limited facilities and infrastructure, variations in educator competence, differences in access to services between regions, and the need for stimulation at home. Competition among early childhood education institutions is quite fierce, driving innovation in learning quality, teacher competence, facilities, and flagship programs. In this context, marketing management plays a strategic role in building the institution's image, conveying information about educational services, identifying community needs, and increasing the institution's competitiveness in an ethical and sustainable manner. TK Muslimat NU Pakembaran, as a religious-based PAUD institution, plays an important role in developing children's development and instilling Islamic values. Although the marketing strategy is still simple and predominantly based on a familial approach and word-of-mouth promotion, these efforts are effective in building community trust and loyalty. In the future, strengthening a more systematic marketing management can increase competitiveness, expand the reach of information, and support the sustainability of the institution in providing quality, religious, and character-building early childhood education services.

Food and beverage companies must maintain a robust capital structure to compete effectively amidst the intense pressures of globalization and achieve their strategic objectives. This study aims to examine the impact of profitability, asset structure, company size, and solvency on the capital structure of food and beverage firms listed on the Indonesia Stock Exchange (IDX) and included in the LQ45 index. This study uses an explanatory method with purposive sampling technique, where samples are determined based on companies that have completed financial reports during the research period and are indexed in LQ45. Data analysis was performed using t-tests and F-tests. The results show that profitability (ROA), asset structure, and company size (Ln Total Assets) do not have a significant partial effect on capital structure (DER), meaning that these three factors do not directly influence companies' decisions on the use of debt for financing. However, solvency (DAR) was found to have a significant effect on capital structure, indicating that a company's ability to meet its long-term obligations plays an important role in determining the level of debt used for operational financing. Simultaneously, the four independent variables had a significant effect on capital structure, meaning that all variables together contributed to influencing food and beverage companies' decisions in determining their financing strategies.

This study aims to analyze the factors that influence economic growth. Economic growth is an important indicator used to measure the success of a country's development because it reflects the increasing capacity of an economy to produce goods and services. This research uses a descriptive approach by examining several factors affecting economic growth, including investment, labor, unemployment, and international trade. The results show that investment plays a significant role in increasing production capacity and encouraging the development of industry and infrastructure. Labor also contributes to economic productivity through the production of goods and services. On the other hand, a high unemployment rate can hinder economic growth because part of the labor force is not absorbed into productive activities. In addition, international trade through export and import activities can support economic growth by expanding markets for domestic products and fulfilling the need for raw materials and technology in the production process. Therefore, economic development policies need to consider these factors to achieve sustainable economic growth and improve public welfare

This paper focuses on a legal review of foreign investment regulations in Indonesia, a crucial aspect that underpins most of the discussion. Furthermore, it frequently highlights the implications of legal regulations on investment, including foreign investment, in several related regulations, such as the Job Creation Law and the Investment Law, for market volatility, corporate governance, and stock prices in Indonesia. This paper emphasizes a normative-empirical context, focusing on a review of capital market investment regulations and secondary analyses conducted through several journals reporting on the effectiveness of foreign investment for local companies, enhancing their image as local companies, a trend inevitably driven by local interests. This is further supported by the use of various important theories, such as foreign investment theory, the legal framework for foreign investment, stock performance theory, and efficient investment, as crucial theoretical considerations in the discussion. The point of the results of the discussion in this writing is then emphasized on its focus, namely the results of the review of the legal regulations regarding capital markets that include foreign capital markets, which also discusses the results of research reports from various journals related to the implications of foreign investment regulations as well as the challenges and discussions of harmonization regarding existing investment regulations in Indonesia.

This study aimed to analyze the effect of credit risk on profitability with liquidity as a mediating variable in banking companies listed on the Indonesia Stock Exchange (IDX) during 2022–2024. The study employed a quantitative approach with an explanatory research design. Secondary data were obtained from annual financial statements, and the sample consisted of 31 banking companies selected through purposive sampling from a total of 47 companies. The research variables included credit risk as the independent variable, profitability proxied by Return on Assets (ROA) as the dependent variable, and liquidity proxied by the Loan to Deposit Ratio (LDR) as the mediating variable. Data were analyzed using Partial Least Squares–Structural Equation Modeling (PLS-SEM) through the assessment of the measurement model and the structural model. The results indicated that credit risk did not affect profitability and did not affect liquidity, while liquidity affected profitability. The findings also demonstrated that liquidity did not mediate the relationship between credit risk and profitability. The study implied that liquidity management played an important role in supporting bank profitability, whereas the influence of credit risk on profitability during the study period was likely driven by other factors outside the proposed model. This study provided empirical evidence on banking performance dynamics in 2022–2024; however, generalization should have been made cautiously due to the limited observation period and the variables included.

Financial performance is an important indicator for assessing the sustainability and growth prospects of a company, where a sustained negative net profit may indicate financial and operational problems (Aminah, 2015). The purpose of this study is to analyze the financial performance of PT GoTo Gojek Tokopedia Tbk for the period 2019-2023 based on NPM, ROA, and ROE. The research method used in this study is a qualitative method with a descriptive analysis approach. The data was sourced from the official website of PT GoTo Gojek Tokopedia Tbk for the period 2019-2023. The results show that all profitability ratios, namely Net Profit Margin (NPM), Return on Assets (ROA), and Return on Equity (ROE), are in an unfavorable condition and far below the standards set by Bank Indonesia (2004), namely NPM 3%–9.5%, ROA 0.5%–1.25%, and ROE 5%–12.5%. NPM was consistently negative from -276.74% (2019) to -373.12% (2023), indicating that the company has not been able to generate net income from its revenue due to high operating expenses. ROA was also negative throughout the period, ranging from -112.57% (2019) to -167.33% (2023), indicating that assets have not been utilized efficiently. Similarly, ROE recorded negative values from -162.02% (2019) to -253.41% (2023), reflecting that shareholders' capital has not been optimally managed and has not provided returns, so that overall financial performance requires a more effective financial management strategy.

Vannamei shrimp (Litopenaeus vannamei) is one of the most important aquaculture commodities with high economic value and strong market demand. The transportation of broodstock shrimp is a critical stage that may affect survival due to decreased oxygen levels and water quality deterioration. High stocking density during transportation can accelerate oxygen depletion and increase metabolic waste, leading to higher mortality. This study aimed to determine the effect of different packing densities on the survival rate of broodstock shrimp during 12 hours of transportation. The experiment used four treatments with densities of 6, 8, 10, and 12 shrimp per bag, each with six replications. Observed parameters included temperature, dissolved oxygen (DO), and survival rate. The results showed that lower stocking density produced higher survival rates, with the best result obtained at 6 shrimp per bag. Water quality remained within acceptable limits, although oxygen levels decreased with increasing density. Therefore, proper stocking density is essential to maintain shrimp survival during transportation.  

This study aims to analyze the political strategies implemented by the Partai Keadilan Sejahtera faction in advocating community aspirations within the North Sumatra Provincial Regional House of Representatives. The research employs a qualitative approach using a descriptive method. Data were collected through interviews, observation, and documentation. Interviews were conducted with Hannah May Lisa as a PKS staff member and Riduansyah as a faction expert staff at the DPRD Secretariat of North Sumatra. The results indicate that the PKS faction’s political strategy in advocating public aspirations involves several stages: gathering community aspirations through recess activities and direct communication with constituents, internal faction discussions to determine priority issues, and political communication and collaboration with other factions and the regional government. In addition, the role of faction expert staff is essential in providing policy analysis and supporting data for the decision-making process. Therefore, faction political strategies play an important role in ensuring that public aspirations are accommodated in regional public policies.

Dividend payment is an important financial decision that reflects a company’s performance and prospects from the perspective of investors. However, companies included in the LQ45 index still experience fluctuations in dividend payment policies from year to year. This study aims to analyze the effect of leverage, firm size, profitability, and liquidity on dividend payments of companies listed in the LQ45 index on the Indonesia Stock Exchange (IDX) during the 2023–2024 period. This research employs a quantitative approach using secondary data obtained from published financial statements. The sample was selected using a purposive sampling method, resulting in 33 companies with a total of 60 observations. Data analysis was conducted using panel data regression with the assistance of SPSS software. Leverage is measured by the Debt to Asset Ratio (DAR), firm size by the natural logarithm of total assets (LnTA), profitability by Return on Assets (ROA), liquidity by the Current Ratio (CR), and dividend payment by the Dividend Payout Ratio (DPR). The results show that leverage, firm size, profitability, and liquidity simultaneously have a significant effect on dividend payments. Partially, firm size and profitability have a positive and significant effect on dividend payments, while leverage and liquidity do not have a significant effect. These findings indicate that companies with larger firm size and higher profitability tend to have a greater ability to distribute dividends to investors.

Organized cross-border crimes that deprive human rights, namely the Crime of Trafficking in Persons (TPPO), often use population migration routes as the main entry route. This research seeks to review how criminal law is applied to trafficking perpetrators who take advantage of immigration access, as well as uncover the obstacles that arise when law enforcement is carried out in the area of the Class II Immigration Office of TPI Belawan. This study adopts an empirical juridical approach with a qualitative analysis framework. Information collection was carried out through the review of regulatory documents and in-depth discussions with officials at the Class II Immigration Office of TPI Belawan. The research findings indicate that enforcement efforts against trafficking cases in the Belawan operational area rely on Law No. 21 of 2007 concerning the Eradication of Trafficking and Law No. 6 of 2011 concerning Immigration. It was identified that the modes of violation that often occur are falsification of travel documents and the abuse of residence permits to facilitate the sending of illegal migrant workers abroad. Significant obstacles faced include challenges in proving criminal elements, disconnection of the perpetrator network, and lack of synergy between law enforcement agencies in the port area. In closing, improving immigration surveillance capabilities and strengthening partnerships are important means to reduce the threat of human trafficking through the sea route in the Belawan area.

UMKM Digital transformation in local governance is an important instrument in realizing the principles of good governance, especially in regions with complex geographical challenges. This study aims to analyze the effectiveness of e-government implementation at the district level in encouraging community participation in the local development planning process, using a case study of the Fof District Office, Tambrauw Regency. The methods used were descriptive qualitative through field observations, in-depth interviews with district officials and community leaders, and analysis of development documents. The data was analyzed through the stages of reduction, presentation, and drawing conclusions. The results of the study show that the implementation of e-government in Fef District is in a transition phase. Bureaucratic digitization improves administrative efficiency and transparency of public information. However, its effectiveness in expanding community participation is still low. The main obstacles include limited telecommunications infrastructure in several villages and low community digital literacy. As a result, participation in Musrenbang remains dominated by conventional mechanisms, while digital platforms serve primarily as a means of one-way reporting. This study emphasizes that the success of digital transformation depends on the readiness of infrastructure and community capacity, so a hybrid approach that integrates technology with local wisdom is needed to strengthen participation in regional development.

Fine motor skills in preschool children begin to develop, where they can use their fingers to write, draw, and so on.

The conclusion is that finger painting and origami can provide a stimulus for the motor development of children aged 4-6 years. Suggestion: Children's developmental stages can be stimulated with various other teaching aids, finger painting and origami are effective teaching aids.

The study aims to analyze in greater depth the influence of work motivation and employee loyalty on employee performance at PT ABC. This research employs a quantitative approach with an explanatory design intended to systematically explain the relationships among variables. Data were collected through the distribution of questionnaires using a Likert scale (1–5) to employees with a minimum of one year of tenure, as they are considered to have an adequate understanding of organizational conditions. Data analysis was conducted using the Structural Equation Modeling–Partial Least Squares (SEM-PLS) method with the assistance of SmartPLS 4 software to obtain more accurate and comprehensive results. The findings indicate that all research indicators have met the established validity and reliability criteria. The structural model test shows that work motivation has a positive and significant effect on employee performance (β = 0.207; p = 0.007), and employee loyalty also has a positive and significant effect (β = 0.718; p = 0.000). The R-square value of 0.753 indicates that both variables are able to explain 75.3% of the variation in employee performance. These findings emphasize that work motivation and employee loyalty play important roles in improving performance, with loyalty being the most dominant factor influencing employee performance.

Curriculum reform in Indonesia has repeatedly emphasized flexibility, deep learning, and student-centered instruction. Nevertheless, many reforms have not been translated effectively into classroom practice. Existing studies tend to focus on teacher competence and policy readiness, while the deeper dimension of teacher beliefs remains underexplored. This study aims to unpack how teacher beliefs shape responses to curriculum reform and to identify the belief-related factors that influence the success or failure of curriculum innovation. A qualitative descriptive design was employed using pre-Delphi reflective questionnaires and Focus Group Discussion data involving senior secondary school teachers and educational stakeholders. Data were analyzed thematically to identify recurring patterns of belief, challenge, and adaptation. The findings reveal that teacher beliefs constitute the most decisive factor in curriculum implementation. Three major themes emerged: (1) a persistent gap between curriculum policy and classroom practice, (2) the difficulty of transforming teachers’ mindsets from fixed to growth-oriented perspectives, and (3) the construction of an ideal teacher identity characterized by reflection, adaptability, collaboration, and moral commitment. More importantly, teachers viewed curriculum change not merely as a technical demand, but as a moral and spiritual responsibility. Curriculum reform will remain ineffective unless it addresses teachers’ internal beliefs. Sustainable transformation requires professional development that integrates cognitive, emotional, and spiritual dimensions of teaching.      

The postpartum period is an important time for the mother's physiological recovery after childbirth, during which various bodily changes are still ongoing and health risks, including changes in blood pressure, may occur. One factor that is thought to affect blood pressure during the postpartum period is dietary patterns, particularly high sodium intake. Salted fish is a food commonly consumed by the community and is known to have a high salt content. This study aims to analyze the effect of salted fish consumption on blood pressure in postpartum mothers from day 1 to day 28. This study used a quantitative approach with an analytical observational design through a cross-sectional method. The study sample consisted of 20 postpartum mothers on days 1–28 who were selected using purposive sampling. The independent variable was salted fish consumption, while the dependent variable was the systolic blood pressure of postpartum mothers. Data were collected through interviews using a structured questionnaire and blood pressure measurements with a standard tensiometer. Data analysis was performed using univariate and bivariate methods. The Shapiro–Wilk normality test showed that the data were not normally distributed, so the analysis was continued with the Wilcoxon test. The results of the study show a significant difference between systolic blood pressure before and after exposure to salted fish consumption, indicating that consumption of foods high in salt affects changes in blood pressure in postpartum women. This study concludes that salted fish consumption has the potential to affect the blood pressure of postpartum women. Therefore, nutrition education related to limiting the intake of foods high in salt during the postpartum period needs to be improved as part of efforts to prevent postpartum hypertension.

This research is entitled The Influence of Japanese Pop Culture on Children’s Toys Trends in Indonesia, 1980-2010. The study employs the historical method, which consists of four stages: heuristics, source criticism, interpretation, and historiography.John Fiske’s (2011) theory of popular culture and  Joseph Nye’s concept of soft power is used to analyze how Japanese popular culture, particularly through entertainment media and toy products, was disseminated persuasively and received by Indonesian children. Since the early 1990s, mass media such as television and children’s magazines have played an important role in introducing Japanese anime and characters, which subsequently encouraged the emergence of toy trends based on Japanese popular culture. The object of this research focuses on children’s toys influenced by Japanese popular culture that circulated in Indonesia between 1980 and 2010, including Tamiya, Beyblade, Tamagotchi, Crush Gear, B-Daman, and yo-yo. These toys not only developed as commercial products, but also contributed to the formation of children’s play patterns, communities, and social identities. However, during the period from 2008 to 2010, these toy trends began to decline due to the advancement of digital technology, changes in children’s consumption patterns, broadcast censorship policies implemented by Indonesian Broadcasting Commission (KPI), and increasing competition from popular culture of other countries such as Korea, the United States, and China. This condition reflects a shift in children’s play culture from physical toys to more modern forms of digital entertainment.

Digital revolution and the disruption of the global labor market have made public organizations, especially vocational training institutions, even more complicated. This study seeks to examine the impact of dynamic skills on institutional resilience, with innovative leadership serving as a mediating variable. The study employed a quantitative methodology, utilizing data collected from 180 employees at the Medan Vocational and Productivity Training Center (BBPVP). We used Structural Equation Modeling based on Partial Least Squares (SEM-PLS) to look at the data. The findings indicate that dynamic capabilities exert a positive and significant influence on institutional resilience, underscoring the necessity for an organization to identify, capitalize on opportunities, and adapt to change. Dynamic qualities also have a big effect on inventive leadership, which is very important for making organizational change happen. Innovative leadership demonstrably influences institutional resilience and serves as a partial mediator between dynamic capabilities and institutional resilience. This research offers a theoretical advancement by synthesizing institutional theory, dynamic capacities, and innovative leadership to elucidate public organizational resilience. In practical terms, the findings of this study have significant significance for enhancing the adaptive capacity of vocational training institutions in the context of digital disruption.
