Abstract

This study investigates the solubility behavior of water molecules on the surface of CuInS₂/ZnS Quantum Dots (QDs) in different solvents using an Ab Initio approach based on Density Functional Theory (DFT). The research evaluates the influence of solvent dielectric constant on surface potential energy and solute-solvent interaction energy. The study reveals that hydrogen bonding, dipole-dipole interactions, and van der Waals forces significantly affect QDs stability and size. The findings indicate that solvents with higher dielectric constants destabilize nanoparticles, leading to electron transfer between particles. Among the tested solvents, chloroform provides an optimal balance between solubility, stability, and band gap (~1.68 eV). These results contribute to a deeper understanding of solvent-mediated effects on QDs, essential for their application in optoelectronics and bio-imaging.

Abstract

Municipal solid waste remains a pressing environmental challenge in the Special Region of Yogyakarta (DIY), characterized by the continuous increase in waste generation, limited waste-management infrastructure, and low levels of public awareness and participation. This study aims to identify and analyze public perceptions and attitudes toward waste management across the five administrative regions of DIY through the distribution of 250 questionnaires administered using a random-sampling technique. The collected data were examined using descriptive statistics, k-means clustering, and heatmap visualization. The findings indicate significant variations in awareness and participation levels based on demographic factors such as age, gender, educational background, occupation, and residential area. The clustering analysis categorized respondents into three groups low awareness (34%), moderate awareness (25%), and high awareness (41%) each requiring different forms of intervention. Beyond the social dimension, the results demonstrate that Islamic ethical principles such as cleanliness as part of faith, the prohibition of environmental destruction (fasād), and the human responsibility as khalifah (stewards of the Earth) serve as an ethical and spiritual foundation that can reinforce community-based waste-management initiatives. Overall, the study concludes that addressing the waste crisis in Yogyakarta requires more than infrastructural solutions; it demands cultural transformation, continuous environmental education, and cross-sector collaboration to build collective ecological awareness and sustainable public engagement.

Abstract

Learning motivation is a fundamental element in the success of higher education, especially in entrepreneurship courses that require creativity, innovation, courage to take risks, and mental toughness. This study aims to analyze the contribution of Islamic psychology concepts in increasing student learning motivation in entrepreneurship learning in Islamic higher education institutions. This study uses a descriptive qualitative method through classroom observation, semi-structured interviews, and learning reflections on students from eight undergraduate programs at Ahmad Dahlan University, namely Psychology, Law, Information Systems, Food Technology, English Literature, Biology, Pharmacy, and Medicine. The results of the study indicate that the integration of Islamic psychological values, including fitrah, religious motivation, tazkiyatun nafs, work ethics, and the concept of ikhtiar tawakal, plays a significant role in increasing student learning motivation, both quantitatively (discipline, participation, and project completion) and qualitatively (deepening the meaning of learning, work ethic, courage to innovate, and resilience in the face of failure). A relatively consistent positive response was found in all study programs, but with nuances of internalization that differed according to the characteristics of each discipline. These findings emphasize the importance of developing an Islamic psychology-based entrepreneurial learning model to produce Muslim entrepreneurial graduates who are competent, have integrity, are resilient, and are oriented towards social benefit.
