ity of empirical field data on screw-pile behavior under repeated loading and to evaluate the agreement between theoretical predictions and actual in situ responses. The methodology employs an experimental approach through in situ testing with screw-pile diameters of 10 cm, 15 cm, and 20 cm, and embedment depths ranging from 0.6 m to 1.0 m. The tests were conducted under both static and repeated tensile loading using a hydraulic jack system, accompanied by vertical deformation measurements to establish load–displacement curves. Theoretical capacity was calculated using a limit equilibrium approach for comparison with experimental results. The findings reveal a nonlinear load–displacement response, characterized by initial stiffness followed by progressive deformation into the post-yield stage. At a maximum load of 2.858 tons, deformation increased with diameter, from 5.10 cm (10 cm) to 8.49 cm (20 cm). Under repeated loading, failure occurred at a lower load of approximately 1.6 tons with a maximum deformation of 1.648 cm, indicating potential capacity degradation due to cyclic loading. The comparison between theoretical and field results shows significant deviations, with analytical predictions generally underestimating the in situ capacity. This highlights the limitations of simplified models that do not fully account for shaft adhesion, installation disturbance, soil heterogeneity, pore-water pressure effects, and cyclic degradation. Overall, this study contributes valuable field pull-out test data for screw piles in clay under repeated loading, emphasizing the need for design calibration based on full-scale testing for slope stabilization applications. The results also suggest opportunities for further research involving long-term monitoring and advanced modeling of cyclic degradation.
Abstract:This study explores the role of brand image, price, promotion, and distribution channels in shaping consumer purchasing decisions for domestically produced industrial LED lighting products. A quantitative research approach…
ch was employed using a survey method, with data analyzed through multiple linear regression. The findings indicate that the proposed model is statistically significant, demonstrating that all marketing mix elements jointly influence purchasing decisions. Each variable also shows a positive and significant individual effect, with distribution channels emerging as the most influential factor in driving consumer decisions. This suggests that ease of access, product availability, and effective distribution play a critical role in the adoption of industrial LED products. The novelty of this research lies in empirically integrating marketing mix factors within the context of domestically manufactured LED products, an area that has received limited scholarly attention. The study offers practical implications for manufacturers, emphasizing the importance of strengthening distribution strategies and aligning pricing and promotional efforts to enhance consumer purchasing decisions
Abstract:The authority of local governments in environmental protection, management, and law enforcement is exercised within the framework of regional autonomy in Indonesia. Under Law Number 23 of 2014 and Law Number 32 of 2009,…
environmental affairs have been decentralized as mandatory governmental functions under the authority of provincial and regency/municipal governments. This study employs a normative juridical research method, utilizing secondary data in the form of statutory regulations and legal literature. The findings indicate that regional autonomy provides local governments with greater capacity to understand and respond to the objective environmental conditions of their respective regions. Environmental law enforcement is implemented through administrative sanctions, criminal sanctions, and civil liability based on the principle of strict liability. The role of local governments is therefore crucial in ensuring the sustainability of environmental functions and in safeguarding community welfare through effective environmental governance.
Abstract:This study applied a Systematic Literature Review (SLR) to identify, appraise, and synthesize open-access empirical evidence on inclusive care models in elderly healthcare. The review followed PRISMA 2020 and searched PubMed,…
bMed, Scopus, Web of Science, DOAJ, and Google Scholar for studies published between 2015 and 2025. Eligible articles were original research (quantitative, qualitative, or mixed methods) focusing on service delivery or care models for older adults and explicitly addressing inclusivity, integration, person-centeredness, or collaborative care, with full-text availability in English or Indonesian. From 1,280 records, 1,010 unique articles were screened, 80 full texts were assessed, and 10 studies were included in the final synthesis. Across studies, inclusive elderly care was most consistently implemented through integrated, person-centred, team-based delivery combining comprehensive assessment, individualized care planning, coordinated follow-up, and cross-sector collaboration. Stronger benefits were typically observed among frail older adults when care intensity was aligned with comlplex needs by risk stratification and case management. Mental health integration emerged as a critical component for community-dwelling older adults, supporting the integration of psychological care into routine elderly healthcare pathways rather than parallel programs. Evidence from institutional settings indicated that partnership-based models involving nurses, caregivers, and older adults can improve functional outcomes. Overall, the findings support scaling integrated community and institutional partnership approaches, while future research should strengthen reporting on implementation fidelity, equity impacts, and cost-effectiveness to guide sustainable adoption of inclusive, gerontic-friendly care models.

Abstract:The health pandemic several years ago had a significant impact on various sectors, especially companies listed on the Indonesia Stock Exchange. This study was motivated by fluctuations in the price of sharia stocks or the…
e Jakarta Islamic Index (JII) after the Indonesian government officially lifted the pandemic status. By combining macroeconomic and company fundamental factors with hierarchical regression analysis techniques, this study aims to identify which combination of factors influences the return on shares in this sector after the pandemic. The results show that the performance of returns on shares in the sharia sector is dominated by fundamental factors, namely Total Asset Turn Over (TATO) and Return on Assets (ROA). The main finding from this research is that post-pandemic, the performance of the Islamic stock sector is still dominated by corporate fundamental factors, which are efficiency and profitability. The limitation of this research lies in the data range, and it would be very interesting to continue with a longer time period. The technical contribution of this research is that it can provide an overview for investors when deciding to invest, so that they can focus more on corporate fundamental factors first.

Abstract:This study examines the effect of financial performance and Corporate Social Responsibility (CSR) on firm value in cement companies listed on the Indonesia Stock Exchange (IDX) during the period 2020–2024. Financial performance…
rformance is proxied by Return on Assets (ROA), while firm value is measured using Price to Book Value (PBV). CSR is measured through a disclosure index based on the Global Reporting Initiative (GRI) Standards using content analysis. This research employs a quantitative associative approach with secondary data obtained from annual reports and sustainability reports of seven cement companies. Multiple linear regression analysis is used to test the hypotheses. The results indicate that ROA has a positive and significant effect on firm value, suggesting that efficient asset utilization enhances market perception. CSR disclosure also shows a positive and significant effect on firm value, supporting the legitimacy theory that socially responsible practices strengthen corporate reputation and investor confidence. These findings highlight the importance of integrating financial performance and sustainability strategies to enhance firm value, particularly in capital-intensive and environmentally sensitive industries such as cement.
Abstract:Calculus of Multiple Variables is a core course in the Mathematics Education study program and plays a crucial role in developing students advanced mathematical thinking skills. Success in this course relies heavily on mastery…
astery of the prerequisite material, particularly the concepts of derivatives and integrals of functions of one variable. Therefore, understanding mathematical concepts is a fundamental aspect that determines students’ ability to understand the interrelationships between topics and solve problems systematically and logically. This study aims to describe students' conceptual understanding of multivariable calculus. The approach used is a descriptive approach with a purposive sampling technique, namely selecting research subjects based on certain criteria in the form of the highest and lowest levels of mathematical concept understanding. The results of the study indicate that students conceptual understanding varies across different materials. In the partial derivative material, students were not yet fully able to accurately represent the solution concept, especially in applying the rules for derivatives of exponential functions, so the results obtained did not conform to mathematical principles. These errors are conceptual in nature and indicate a weak grasp of certain basic concepts. However, in the material on derivatives of products of two functions and triple integrals, students demonstrated goog conceptual understanding. They were able to select, use, and apply solution procedures appropriately and systematically. This finding indicates that despite weaknesses in certain concepts, students still possess quite good procedural and conceptual abilities in the context of other problems in polynomial calculus.
