these tenets translate into measurable welfare outcomes across heterogeneous developing nations remains highly fragmented. This study addresses this critical gap by executing a systematic literature review guided by the PRISMA 2020 statement to synthesize empirical evidence on the operationalization of Zakat, Waqf, and Islamic Social Finance (ISF) as structural instruments for poverty reduction. Departing from traditional descriptive reviews, this paper introduces an original analytical taxonomy that maps the operational mechanics of ISF against micro-level and macro-level development outcomes. Based on a rigorous multi-stage screening of peer-reviewed empirical studies published between 2020 and 2025 across emerging economies, a final synthesized sample of $n = 10$ high-quality primary articles was evaluated. The qualitative narrative synthesis reveals that integrated ISF instruments exert a structurally positive impact on poverty alleviation, income optimization, and socio-economic empowerment, particularly when embedded within digital financial ecosystems and formal financial inclusion frameworks. However, the analysis uncovers substantial outcome heterogeneity, demonstrating that welfare efficacy is highly conditional upon institutional governance quality, targeting accuracy, and localized implementation designs. The structural novelty of this research lies in its empirical crystallization of the explicit boundary conditions under which normative faith-based capital successfully disrupts poverty traps, offering an evidence-based operational blueprint for policymakers and Sharia social institutions in the Global South.

er distribution and its impact on rice productivity in the tidal lowland areas of Tanjung Lago District, Banyuasin Regency. The research employed both quantitative and qualitative descriptive approaches using a stratified random sampling method involving 60 farmers who received subsidized fertilizer and 30 farmers who did not reveive subsidizer fertilizer. The effectiveness of subsidizer fertilizer distribution was evaluated using a likert scale based on the Six Appropriateness Principles, while the impct on rice productivity was analyzed by comparing the productivity levels of the two farmer groups. The findings showed that the distribution of subsidized fertilizer was generally categorized as moderately effective, with an average effectiveness score of 71,33%. The price compliance indicator was classified as highly effective (91,66%), while location suitability was categorized as effective (81,00%). Meanwhile, quantity appropriateness, fertilizer type suitability, and timeliness of distribution were categorized as moderately effective. The findings showed that the distribution of subsidized fertilizer was generally categorized as moderately effective, with an average effectiveness score of 71.33%. The price compliance indicator was classified as highly effective (91.66%), while location suitability was categorized as effective (81.00%). Meanwhile, quantity appropriateness, fertilizer type suitability, and timeliness of distribution were categorized as moderately effective. In contrast, the fertilizer quality suitability indicator was still considered ineffective, with an effectiveness score of 55%. The use or subsidized fertilizer also contributed positively to rice productivity. Farmers receiving subsidized fertilizer achieved an average rice productivity of 3.77 ton ha⁻¹, whereas farmers who did non receive subsidized fertilizer produced an average productivity of 3.20 ton ha⁻¹. This resulted in a productivity defference of 0.57 ha⁻¹.. equivalent to approximately 17.81%.

atant cultures derived from mouse cell immunoglobulin hybridization. Examination of blood type with serum is an examination that uses blood type A as anti-B, blood type B as anti-A, and blood type O as anti-AB. The purpose of this study was to determine the profile of the ABO system blood group examination using antisera reagents and serum slide method. The research method used was descriptive with samples of the ABO system blood group using antisera and serum reagents for 30 respondents using probability sampling technique. The materials used are human blood groups A, B, AB and O and anti-A, anti-B, anti-AB reagents. Data analysis was descriptive in the form of a profile table of the results of the ABO system blood group examination using antisera and serum reagents. The results of the study revealed that the results of blood group A were 7 (23%), blood group B were 7 (23%), blood group AB were 8 (27%), and blood group O were 8 (27%). The results obtained showed that the antisera and serum reagents had differences in the blood group examination results, namely the grade of agglutination produced by the serum was different from that of the antisera. It can be concluded that the results of blood grouping with antisera and serum reagents can be used for blood group examination. However, compared to antisera reagents, the results are better using antisera reagents compared to serum.
Abstract:This study examines how core marching band structures can be adapted for Indonesian early childhood education through developmentally appropriate practice and performance theory. The study responds to concerns that preschool…
hool marching band activities may reproduce discipline-oriented rehearsal models designed for older learners. A one-group pre-test and post-test mixed-methods design was used with twenty Indonesian preschool children aged four to five years. Over six weeks, children participated in twelve adapted marching band sessions that combined simplified rhythmic patterns, child-scaled instruments, neat but developmentally adjusted formations, cooperative music-making, visual-motor activities, and responsive teacher facilitation. Quantitative data were collected using a four-point developmental observation rubric covering rhythmic competence, motor coordination, and socio-emotional engagement. Qualitative data were obtained from teacher reflective journals and post-intervention interviews. Paired-sample analysis showed higher post-test scores across the three developmental domains. The largest observed improvement appeared in socio-emotional engagement, followed by rhythmic competence and motor coordination. However, because the study did not include a control group, the findings should be interpreted as developmental changes observed after participation rather than definitive causal effects of the intervention. Qualitative findings indicated that children participated more confidently when teachers simplified rhythmic tasks, used clear and neat formations with reduced technical pressure, provided child-scaled instruments, supported safe movement, and acted as co-players and emotional co-regulators. The study reconceptualizes marching band routines not as rigid disciplinary scripts, but as adaptable performative frames that may support social participation, emotional regulation, rhythmic learning, motor coordination, cooperation, and creative agency when aligned with children’s developmental readiness.
Abstract:Passenger movement within aircraft aisles is an essential activity during the flight process, particularly inside narrow-body aircraft where mobility remains restricted. Interactions between passengers frequently trigger…
avoidance behaviors that potentially influence perceptions of safety, security, and comfort during travel. Therefore, this study aims to analyze passenger perceptions of aisle avoidance on Pelita Air flights based on these three specific dimensions. Methodologically, the research utilizes a quantitative descriptive approach involving a five-point Likert scale questionnaire. Data were gathered from 350 respondents who previously utilized Pelita Air flight services. Furthermore, the analysis was conducted by calculating mean values to determine the categorization of respondent perceptions. Findings indicate that all variables fall within the “good” category. Specifically, the mean value for safety reached 4.098, security 4.099, and comfort 4.077. Effectively, these findings demonstrate that the avoidance process in the cabin aisle is perceived as safe, orderly, and sufficiently comfortable despite the limited space for movement. Importantly, this study contributes to the understanding of passenger behavior in confined cabin spaces and becomes valuable input for airlines to enhance the quality of cabin services.
Abstract:Karstification is the dominant geological process controlling groundwater circulation and permeability in carbonate aquifers. Through the dissolution of carbonate rocks, karst processes create highly heterogeneous systems…
s characterized by fractures, conduits, and interconnected channel networks that significantly influence groundwater flow dynamics. This literature review aims to synthesize current knowledge regarding the effects of karst on water circulation and permeability in carbonate aquifers based on hydrogeological, hydrochemical, geophysical, and numerical modeling studies from various regions worldwide. The review shows that karstification substantially enhances hydraulic conductivity and produces complex flow regimes ranging from diffuse fracture flow to turbulent conduit flow. The epikarst zone plays an important role in regulating infiltration and recharge distribution, while tectonic structures such as faults and fractures strongly control groundwater pathways and aquifer compartmentalization. Karst aquifers also exhibit strong spatial variability in permeability, making groundwater flow and contaminant transport difficult to predict using conventional hydrogeological approaches. In addition, the integration of equivalent porous medium (EPM), discrete fracture network (DFN), and conduit network (CN) models is essential for accurately representing karst aquifer behavior. Understanding the influence of karstification on groundwater circulation is therefore crucial for sustainable groundwater management and aquifer vulnerability assessment, particularly in regions facing increasing water demand and climate change pressures.

examines the effects of Return on Assets (ROA), Current Ratio (CR), Debt-to-Equity Ratio (DER), Sales Growth (SG), and Firm Size (SIZE) on Dividend Payout Ratio (DPR), as well as the impact of DPR on stock returns. The research employs a quantitative approach using secondary data obtained from the annual financial reports of dividend-paying companies listed on the IDX. The sample consists of 822 firm-year observations selected through purposive sampling. Data analysis was conducted using path analysis with multiple regression models, supported by classical assumption tests including normality, heteroscedasticity, multicollinearity, and autocorrelation tests. The results indicate that during the overall period of 2019–2024, ROA, DER, and SG significantly and negatively affect DPR, while CR and SIZE do not have significant effects. Furthermore, CR negatively affects stock returns, whereas SG and DPR have positive and significant effects on stock returns. The findings also reveal that the relationships among financial performance, dividend policy, and stock returns vary across pre-crisis, crisis, and post-crisis periods. Overall, dividend policy plays an important mediating role in influencing stock returns, particularly during and after periods of financial uncertainty. These findings provide valuable insights for investors, corporate managers, and policymakers in formulating dividend and investment decisions under different economic conditions.

by shifting toward a Business-to-Business (B2B) Digital model to maintain relevance amidst increasingly competitive and dynamic global business competition. This shifting phenomenon demands comprehensive internal readiness, particularly regarding resource orchestration and marketing ambidexterity maturity to balance traditional connectivity business with the exploration of high-value digital service innovation. This research employs a quantitative methodology with descriptive and causal approaches to dissect and objectively measure the level of organizational readiness in facing such market disruptions. Primary data collection was conducted with 385 respondents consisting of employees and strategic stakeholders involved in the transformation process at PT Telkom Indonesia using a nonprobability sampling technique with a purposive sampling method. All collected data were subsequently processed and tested using the SmartPLS version 4 analysis tool to ensure accuracy in modeling the complex relationships between the variables. The data analysis techniques utilized include descriptive statistics to provide a general overview of the data and variance-based Structural Equation Modeling (PLS-SEM) to test the significance of relationships between latent variables within the research model. The research findings project that corporate strategy significantly and positively influences business transformation success and B2B Digital model development, while simultaneously providing a strong direct impact on strengthening the company's competitiveness at the global level. The analysis results also indicate that internal transformation effectiveness and the implementation of B2B digital solutions are primary determinants capable of substantially enhancing the company's ability to compete across borders in the digital platform era. Furthermore, the mediating roles of business transformation and B2B Digital model variables have proven to be crucial in reinforcing the link between corporate strategic orientation and the achievement of sustainable international competitive advantage. Overall, this study provides an empirical foundation regarding the importance of precise resource orchestration for Telkom Indonesia to realize its vision as a preferred digital telco capable of winning competition in international markets.
Abstract:This study aims to examine the strategic role of professional associations in early childhood education policy implementation, focusing on HIMPAUDI East Kalimantan. Non-formal early childhood educators in developing regions…
ons face severe structural vulnerabilities, characterized by a substantial policy gap between central government expectations and local capacities, geographical isolation, and low digital literacy. Utilizing a descriptive qualitative design, this research gathered empirical data through in-depth interviews with the Regional Head of HIMPAUDI East Kalimantan and document analysis. The findings reveal that the association does not merely serve as a gathering platform but functions as a vital strategic partner for local governments. Through multi-layered communication, self-funded tiered training programs, and data-driven political lobbying, the association successfully translates rigid macro-regulations into applicable classroom practices while securing local financial incentives for marginalized educators. This community-based resilience mechanism effectively mitigates administrative burdens and compensates for local government bureaucracy delays. The study implies that local governments should transition toward a co-governance model by formally involving professional networks in policy formulation to ensure equitable educational quality in the new capital city (IKN) era.

ata were collected by distributing questionnaires to 38 respondents selected using a census sampling technique (total sampling). Data analysis techniques included classical assumption tests, multiple linear regression analysis, and hypothesis testing (t-tests and F-tests) using Statistical Package for the Social Sciences (SPSS) version 26 software. The results indicate that, partially, auditor experience has no significant effect on auditor performance, while self-efficacy has a positive and significant effect on auditor performance. Simultaneously, auditor experience and self-efficacy have a significant effect on auditor performance. The coefficient of determination indicates that 73.1% of the variation in auditor performance can be explained by auditor experience and self-efficacy, while the remaining 26.9% is influenced by factors outside the research model.
