This study aims to examine the relationship between the service quality of educational institutions and consumers’ purchase intentions. The research is motivated by the growing importance of institutional quality in maintaining the competitiveness and sustainability of educational institutions in an era of rapid change. A quantitative research design was employed using a simple correlation analysis to identify the degree of association between the two variables. The study involved 100 respondents, consisting of parents of students, selected through a cluster sampling technique from four regions where the elementary schools are located. Data were collected through a structured questionnaire, and the results of the item analysis indicated that all questionnaire items demonstrated high validity and reliability. These findings suggest that the data are highly credible and that the conclusions drawn from the analysis are reliable. The results of the correlation analysis revealed a significant positive relationship between service quality and purchase intention. This implies that the higher the perceived quality of services provided by the educational institution, the greater the consumers’ willingness to enroll or recommend the institution.

The construction industry requires advanced monitoring systems to ensure infrastructure safety and sustainability. This study develops a real-time structural health monitoring system integrated with the Internet of Things (IoT) and deep learning-based analytics to enhance structural safety during and after construction. The proposed system incorporates multiple smart sensors and employs a Long Short-Term Memory (LSTM) model to detect early structural deformations and predict potential failures. The experimental results demonstrate that the IoT-based monitoring system significantly improves accuracy in tracking humidity (92.4%), temperature (94.8%), pressure (94.1%), and vibration (97.2%) compared to conventional manual inspections. A comparative analysis with global implementations in Singapore and Japan highlights the efficiency of edge computing integration in reducing latency and improving data reliability. The findings underscore the importance of integrating deep learning with IoT to enhance predictive maintenance in the construction industry. This research contributes to the development of a more accurate, real-time, and scalable monitoring system for ensuring infrastructure resilience and sustainability.

This study investigates the integration of drone mapping technology with Building Information Modeling (BIM) to enhance accuracy and efficiency in construction projects. By utilizing LiDAR-equipped drones, the research demonstrates significant improvements in topographic mapping, reducing error rates to less than 2% compared to 10% with conventional surveying methods. Additionally, the integration of real-time drone data into BIM optimizes design precision and streamlines project coordination. The study's findings highlight a substantial reduction in survey time and an increase in decision-making accuracy. Despite the benefits, challenges such as high initial investment and workforce training remain obstacles to widespread adoption. This research provides insights into overcoming these barriers and presents a framework for future advancements in drone-BIM integration for construction efficiency

Soil stabilization is a crucial aspect of geotechnical engineering aimed at enhancing bearing capacity and structural load resistance. Conventional methods, such as cement and lime, are commonly used but contribute to high carbon emissions, necessitating the exploration of more sustainable alternatives. One promising approach is the utilization of nanomaterials in soil stabilization. This study evaluates the effectiveness of nano-silica, nano-clay, and graphene oxide in improving soil properties and identifies the optimal dosage for practical applications. Laboratory experiments were conducted to measure Unconfined Compressive Strength (UCS), permeability, and dry density following nanomaterial treatment. The results demonstrate that graphene oxide (1.5%) yields the highest UCS increase, reaching 330 kPa, compared to 120 kPa in untreated soil. Nano-silica (2.5%) also significantly improves UCS to 315 kPa, while nano-clay (3.0%) exhibits the most effective permeability reduction to 6.2 × 10⁻⁵ cm/s. Statistical analysis using Response Surface Methodology (RSM) confirms that an optimal nanomaterial dosage can effectively enhance soil stability without compromising other physical properties. This study contributes to the advancement of nanotechnology applications in geotechnical engineering, providing an efficient and environmentally friendly alternative to conventional stabilization techniques. The findings offer a foundation for real-world implementation of nanomaterial-based soil stabilization and support the development of more sustainable infrastructure solutions.

Pendapatan nasional adalah keseluruhan jumlah pendapatan yang diakses masyarakat di suatu negara dalam rentang waktu satu tahun. GDP atau GNP riil yang diagungkan dalam sistem ekonomi konvensional sebagai parameter kesejahteraan ekonomi turut menuai kritik para ekonom Muslim. Tujuan penulisan ini adalah menganalisis pendapatan nasional yang dilakukan Pemerintah Indonesia di tinjau dari Perspektif Ekonomi Islam. Metode penulisan berdasarkan studi pustaka (content analysis). Hasil penulisan menunjukkan bahwa pengelolaan pendapatan nasional lebih mengarah pada sistem ekonomi konvensional, sehingga cenderung bersifat kapitalis dan belum sepenuhnya untuk kesejahteraan masyarakat sebagaimana dasar dari tujuan berbangsa dan bernegara.

This study aims to examine the influence of moral disengagement and peer support on cyberbullying behavior among adolescents. The population in this study are all adolescents who have Instagram accounts and are in the adolescent development stage in the Jabodetabek area. The research sample consisted of 78 adolescents aged 15-18 years who actively use Instagram social media accounts. The data collection method was conducted through an online survey using a questionnaire distributed randomly to teenagers in the Jabodetabek area. Data processing was carried out using Partial Least Squares Structural Equation Modeling (PLS-SEM) analysis through Smart PLS software. The results showed that moral disengagement has a significant influence on cyberbullying behavior. Adolescents with high levels of moral disengagement tend to have more frequent cyberbullying behavior. Furthermore, this study also found that peer support has a significant effect on cyberbullying behavior. In this case, positive social support from peers can reduce the tendency of cyberbullying behavior, while negative support can actually increase this behavior. This study provides new insights into the factors that influence cyberbullying behavior among adolescent Instagram users. The findings can be used as a basis for the development of interventions aimed at reducing cyberbullying behavior among adolescents, as well as providing recommendations for relevant stakeholders to design effective prevention programs

Writing is one of the essential skills in learning English; however, many students face challenges in organizing ideas coherently, using correct grammar, and maintaining motivation to write. These difficulties often arise from the lack of engaging and relevant teaching strategies. In response to this issue, this study aims to examine the effectiveness of visual-based techniques, namely mind mapping and picture series, in enhancing students' descriptive text writing skills. This research adopted a quasi-experimental design with a non-equivalent control group. Two groups of students—experimental and control—participated in the study. The experimental group was taught using visual techniques (mind mapping and picture series), while the control group followed conventional methods. Pre-tests and post-tests were conducted to evaluate the students' writing performance before and after the intervention. The findings revealed that the experimental group showed a significant improvement in descriptive writing skills compared to the control group. Specifically, mind mapping helped students systematically organize their ideas, while picture series provided visual stimuli that enhanced creativity and engagement. Statistical analysis demonstrated that both techniques effectively addressed students' writing challenges and boosted their motivation. The study concludes that visual-based teaching techniques are beneficial in improving students' ability to produce well-structured, coherent, and engaging descriptive texts.
