0 cma = 5.0 \, \text{cm}a = 5.0 cm (major axis) and b=2.5 cmb = 2.5 \, \text{cm}b = 2.5 cm (minor axis). The applied stresses at infinity are a tensile stress of σ1=100 kg/cm2\sigma_1 = 100 \, \text{kg/cm}^2= 100 kg/parallel to the major axis and a compressive stress of σ2=−100 kg/cm2\sigma_2 = -100 \, \text{kg/cm}^2= -100 kg/ perpendicular to the major axis. The material properties include Young's modulus E=2.1×106 kg/cm2E = 2.1 \times 10^6 \, \text{kg/cm}^2E = 2,1. kg/ and Poisson's ratioν=0.3\nu = 0.3 = 0.3. Using analytical solutions from classical elasticity theory, the maximum tangential stress at the edge of the ellipse is calculated as σmax=600 kg/cm2\sigma_{\text{max}} = 600 \, \text{kg/cm}^2= -600 kg/, yielding a stress concentration factor of kσ=σmax/σ=6k_\sigma = \sigma_{\text{max}} / \sigma = 6 = =6. Additionally, a finite element (FE) analysis based on the Salerno and Sahoni problem for a quarter section of the plate results in kσ=3.1125k_\sigma = 3.1125 = 3.1125 for a configuration with s/r=5s/r = 5s/r = 5, showing a discrepancy of 1.3% compared to the theoretical value of kσ=3.1k_\sigma = 3.1= 3.1 from Peterson's Stress Concentration Factors. The results demonstrate good agreement between the calculated model and theoretical predictions, validating the accuracy of the FE approach for stress concentration analysis in such configurations.
Abstract:The advancement of digital technology has paved the way for the emergence of various mobile learning applications increasingly used within the context of Islamic education. This phenomenon not only reflects the trend of…
integrating technology into modern learning systems but also raises fundamental questions about how these applications are designed and how far they impact learners’ experiences and learning outcomes. This article presents a systematic review of scholarly studies discussing the use of mobile applications in Islamic studies education. The review focuses on two key aspects: the design principles employed in application development and the learning outcomes achieved following their use. The review involved selecting literature from the past six years using specific inclusion criteria, including content relevance, source credibility, and its connection to mobile learning practices in Islamic education. Analysis reveals that designs considering cultural appropriateness, user interface interactivity, and integration of Islamic values positively influence students' emotional engagement, motivation, and content comprehension. Learning outcomes also extend into affective and spiritual domains, not merely cognitive. These findings serve as an initial foundation for developers and educators to build an adaptive, meaningful, and value-based Islamic mobile learning ecosystem.
Abstract:This research examines the impact of gadget use on early childhood social interaction within the urban setting of XYZ Village, Surabaya, amid the growing prevalence of digital exposure among young children. Anchored in Vygotsky’s…
ygotsky’s Sociocultural Theory and the Socialisation Theory, the study evaluates how the duration and frequency of gadget use influence key social competencies, including verbal communication, cooperative behavior, and empathy in children aged 3 to 6 years. Employing a quantitative, cross-sectional design, the study collected data from 100 children using parent-administered questionnaires and direct observational methods, followed by analysis through multiple linear regression. The findings demonstrate that both the duration and frequency of gadget use exert a statistically significant influence on children’s social interaction (p < 0.05), accounting for 19% of the variance (R² = 0.190). The remaining variation is likely influenced by external variables such as parenting styles, digital content quality, and psychological factors. These outcomes underscore the importance of regulated gadget use, active parental involvement, and integrative educational practices that promote both digital literacy and interpersonal development.
Abstract:This research aims to analyze the comparison of character education system curricula in Indonesia and Finland. The focus of the research is to identify differences and similarities in the approach, implementation and effectiveness…
ectiveness of character education in the two education systems. The research method used is a literature study with a qualitative approach. Data was collected through reviewing curriculum documents, education policies, and scientific articles related to character education in Indonesia and Finland. The research results show that Finland integrates character education holistically in all aspects of learning, while Indonesia still tends to separate character education as a separate subject. Apart from that, Finland emphasizes the formation of values of independence, responsibility and collaboration through a student-centered approach, while Indonesia places more emphasis on religious values and nationalism. The implication of this research is the need to reorient the character education curriculum in Indonesia to better integrate character values in the entire learning process, as well as adopting best practices from Finland which have been proven effective in shaping students' character.

ports from 2012 to 2021. The findings indicate that capital structure significantly affects the company's value, with a T-test result showing a calculated value of 5.686, which exceeds the t-table value of 1.89458, and a significance level of 0.031 (less than 0.05). Profitability also has a significant impact, with a calculated value of 5.686 surpassing the t-table value of 1.89458 and a significance level of 0.001 (less than 0.05). This suggests that both capital structure and profitability individually affect the company's value. Additionally, when considered together, capital structure and profitability have a combined significant impact on firm value, with a significance level of 0.002 (less than 0.05) and a calculated F-value of 17.413, which is greater than the F-table value of 4.74. This confirms that both factors together significantly influence the company's value
