M. Munir, Akhmat Fanani Ridho, Juni Iswanto, M. Burhanuddin Ubaidillah, Toha Ma'sum, Syaiful Muda'i, Niken Ristianah
Abstract: This study examines the management processes involved in developing green infrastructure for Islamic educational institutions, specifically focusing on the construction of madrasah buildings using green building concepts.… . It investigates how environmental sustainability principles can be systematically integrated into the planning, design, construction, and operational phases of madrasah development projects. Utilizing a qualitative case study approach combined with document analysis, this research analyzes two madrasah building projects in Indonesia that have implemented green building strategies. Data were collected through in-depth interviews with project managers, architects, contractors, madrasah leaders, and stakeholders, alongside analysis of project documents, designs, and specifications. Findings reveal that successful implementation requires an integrated management approach encompassing green design adaptation to local context, sustainable material sourcing, energy and water efficiency integration, waste management during construction, and life-cycle cost considerations. The study identifies key enablers including leadership commitment, technical expertise, community participation, and Islamic ethical alignment, while highlighting challenges such as budget constraints, regulatory gaps, and technical capacity limitations. This research contributes a framework for madrasah green building project management that balances environmental responsibility with educational functionality and Islamic architectural values.

Greening the System: Implementation of Green Technology in Administrative and Learning Management within Islamic Education Institutions

Miftahul Janah, Roza Ghozwatul Fauziah, Qurrotul 'Aini, Eva Varkatun Nazilah, Niken Ristianah
Abstract: This study explores the implementation of Green Technology (Greentech) in the dual domains of administrative management and pedagogical processes within Islamic education institutions (madrasahs, Islamic schools, and pesantren).… antren). It investigates the potential of Greentech—encompassing energy-efficient hardware, paperless systems, cloud computing, digital learning platforms, and IoT-based resource monitoring—to reduce environmental impact while enhancing operational efficiency and learning outcomes. Employing a mixed-methods sequential explanatory design, the research first surveyed a broad sample of institutions to map adoption levels, followed by in-depth case studies of early adopters. Findings indicate significant potential for reducing carbon footprint and operational costs through virtualization of services, e-learning integration, and smart facility management. However, major challenges persist, including high initial investment, digital literacy gaps among educators, concerns over technology's influence on traditional Islamic pedagogy (talaqqi), and inadequate technological infrastructure. The study concludes that a strategic, values-driven approach aligning Greentech adoption with maqashid sharia (particularly hifdz al-mal/resource preservation) is crucial. It presents a phased integration model that prioritizes technologies offering both environmental and educational benefits, advocating for a balanced fusion of technological efficiency and the preservation of relational, character-based Islamic learning.

THE RELATIONSHIP BETWEEN THE PROMOTION MIX AND THE COMPANY'S BRAND IDENTITY WITH CUSTOMER SATISFACTION AT PT. INO WANGSA BINJAI

Budi, Ivan Benedict Tambunan
Abstract: This study aims to deepen the understanding of the contribution of promotion and branding to increasing customer satisfaction at PT. Ino Wangsa Binjai. The study used primary data with a population of 300 buyers, and 75&#8230; respondents were selected as samples through calculations using the Slovin formula. The analysis techniques applied were quantitative, including validity tests, reliability, classical assumptions, simple linear regression, and hypothesis testing through t-tests and coefficients of determination (R²). Based on the analysis results, the promotional mix variable (E_Prmsi) obtained a t-count value of -1.824 with a significance level of 0.072 (> 0.05), while the t-table was 1.99346. Because the t-count is smaller than the t-table, it can be concluded that the promotional mix does not have a significant effect on customer satisfaction. In addition, a negative t-value indicates that the direction of the relationship between the promotional mix and customer satisfaction is not in line. Conversely, the partial test shows that the company's brand variable has a significant effect on customer satisfaction with a significance value of 0.00 (< 0.05). Therefore, the first hypothesis (H1) is declared accepted. From the results of the determination coefficient test, the R Square value is 0.495, which indicates that 49.5% of changes in customer satisfaction can be explained by the company's promotional mix and brand factors, while the remaining 50.5% is influenced by other variables not examined in this study. As a recommendation, the management of PT. Ino Wangsa Binjai, especially the branch manager, is advised to implement a more cost-effective, efficient, and targeted promotional strategy, as well as utilizing social media such as Facebook, Instagram, Twitter, and print media such as newspapers to convey promotional information more effectively.

Harapan Panjaitan
Abstract: The purpose of this study was to determine the effect of Canva Assisted Mission Based Learning Version on students' Physics learning outcomes on the Measurement material of class X Semester I of SMA Parulian 2 Medan in the&#8230; he 2023/2024 Academic Year. This type of research is a quasi-experimental study. The population of this study was all students of class X MIA semester I of SMA Parulian 2 Medan which includes 2 subjects with a total of 30 students. Sampling was carried out by General Sampling where the number of samples was equal to the number of populations, so that the sample in this test changed to 15 students of class X MIA 1 as an experimental model, who were taught to use Canva. Assisted efforts based on the purchase of model information and 15 students of sophistication X MIA 2. as beauty manipulation were taught with a direct introduction model assisted with Canva. The research device used a multiple-desire view at along with 14 items with five choices (a, b, c, d, and e) which had been tested beforehand to determine the validity, reliability, level of difficulty, and item differentiation. Before examining the hypothesis, the normality and homogeneity of the records were checked first. The results show that the general pretest score for the test is 43.20 with a complete deviation of 8.23 and for the ordinary one is forty-two.75 with a standard deviation of seven, sixty-four. For preliminary competency tcount = 0.329 and ttable = 2.05. shows that tcount < ttable, then the initial talent of both classes is identical. After getting knowledge about ending, the post-test changed to finished for both lessons and the average trial cost changed to 80.79 with an average difference of 8.68 while for the elegance of manipulation the publication test cost became 72.67 with a current deviation of 8.15. Based on the pre-test homogeneity test, it was obtained Fcount = 1.162 along with Ftable = 2.48. because Fcount (1.162) < Ftable (2.48), then the pretest research fact turned out to be homogeneous, then the publish-check homogeneity test obtained Fcount = 1.213 along with Ftable = 2.48. because Fcount (1.213) < Ftable (2.48) then the post-test research data is homogeneous, then the statistical test (one-tailed t-test) obtained tcount = 2.67 and ttable = 1.70 at a significance level of α = 0.05, with dk as much as 28. Because tcount > ttable, being unique (2.67 > 1.70), this indicates that there may be a very large effect of the Canva Assisted learning-based task version on Physics students gaining knowledge about the results in the problem of interweaving of sophistication X Semester I personal strengths of the Parulian 2 Medan faculty in the 2023/2024 academic year.
