The problem-based education model begins with posing a problem or posing a problem, focusing on disciplinary relationships, investigation, group collaboration, as well as creating work, demonstrating and solving the given case. This problem-based education is student-centered, where teachers only share a little data and students who want to be more active in solving problems. This problem-based education uses real (authentic) problems that are unstructured and open-ended as a context for students to improve their problem-solving and critical thinking skills, and at the same time build new knowledge. In contrast to conventional education where real problems are used as the implementation of concepts, problem-based education makes real problems a factor in students' learning process before they understand formal concepts.

Unemployment is a significant economic problem that can affect society's well-being. In an Islamic economic perspective, unemployment is viewed through the lens of social justice, equitable distribution of wealth, and other sharia principles. The causes of unemployment in an Islamic economy include unfair distribution of wealth, lack of relevant education and skills, injustice in the conventional interest-based financial system, and economic and political instability. To overcome unemployment, Islamic economics offers solutions through the effective implementation of zakat, alms and waqf, the use of profit-sharing-based financial instruments such as mudharabah and musyarakah, as well as investment in education and skills training. The government also plays an important role in creating an environment that supports job creation through fair and stable policies. Encouraging entrepreneurship through training and access to capital is also an effective strategy in reducing unemployment. This holistic approach not only aims to reduce unemployment levels, but also to create a more just and prosperous society in accordance with Islamic economic principles.

Solar energy is one of the most promising renewable energy sources to support the transition toward clean energy, yet conventional solar cell technology still faces efficiency limitations. Perovskite materials offer a potential solution due to their superior optoelectronic properties, although challenges related to stability and toxicity remain. This study aims to analyze the interaction of electromagnetic waves with perovskite materials and to evaluate the effect of nano-scale anti-reflective coatings on improving energy conversion efficiency. The research employed a combination of electromagnetic simulations using specialized software and laboratory experiments with miniature perovskite solar cell prototypes. Simulation results demonstrated higher electromagnetic field intensity within the active layer after the addition of anti-reflective coatings, with photon absorption increased by 15–18%. Experimental validation revealed that the energy conversion efficiency improved from 16.8–17.5% without anti-reflective layers to 20.5–21.3% with TiO₂- and SiO₂-based coatings. Optical characterization using a spectrophotometer confirmed enhanced light absorption up to 90% at specific wavelengths, while SEM analysis showed that smoother and more uniform SiO₂ coatings contributed to superior performance compared to TiO₂. Minor discrepancies between simulation and experimental results were attributed to fabrication variations, yet both approaches exhibited consistent improvement trends. These findings highlight that integrating perovskite materials with nano-scale anti-reflective coatings is a key strategy for enhancing the efficiency of next-generation solar cells while supporting future clean energy sustainability.

The development of Islamic banks is considered to have a positive impact on improving the economy of the community, which creates the impression that the revival of the Islamic economy is part of the revival of the Muslim economy. This is marked by the enthusiasm of the community in welcoming the presence of Islamic banks. This study uses a normative juridical method that focuses on the analysis of the application of positive legal norms or legal rules that apply in Indonesia, as well as the approach taken through relevant laws and regulations, with a conceptual approach. The implementation of Islamic banking law in the Indonesian banking system is regulated through the Banking Law, which shows the existence of Islamic banking in Indonesia. However, in reality, the application of sharia principles in the banking sector is still mixed with conventional banking, so that Islamic banks are often considered only as a title, because they have not been able to operate independently and fully implement the sharia principles that they should.
