The increasing demand for housing in tropical regions requires building materials that are fast to apply, environmentally friendly, and resilient to extreme climate conditions as well as disaster risks. Conventional interlocking bricks are often chosen for their ease of construction, yet they still face challenges such as moisture and early cracking. This study proposes the innovation of the Hybrid Living Green Brick, a combination of lightweight bricks made from rice husk ash and fly ash waste (FRCB) with a biological layer of cyanobacteria. FRCB improves compressive strength by approximately 30% with the addition of 5% rice husk ash, achieving 65 kg/cm², thereby meeting Class 50 requirements (≥50 kg/cm²) according to SNI-15-2094-2000. The incorporation of 3% cyanobacteria provides an additional though not significant strength improvement, while still within the Class 50 category. It also reduces brick weight by 4.3%, with further optimization potential through cyanobacteria integration, and lowers carbon emissions from the firing process. Cyanobacteria induce the formation of CaCO₃ layers that seal pores, reduce water absorption by an average of 10%, and provide self-healing properties for microcracks. Preliminary observations indicate that FRCB offers stable mechanical performance, while biological activity was observed on the 7th day with the formation of pale-white mineral layers continuing until the 28th day. This hybrid innovation shows potential to support sustainable and disaster-resilient tropical construction by combining the mechanical strength of waste-based materials with the biological durability of cyanobacteria against extreme climates. Despite challenges related to moisture control and production standardization, the Hybrid Living Green Brick concept opens new pathways for developing environmentally friendly construction materials that are more adaptive to disaster-prone tropical conditions.

Breach of contract disputes with small claim values are often hindered by the lengthy and costly conventional litigation process. To address this issue, the Supreme Court issued PERMA No. 2 of 2015, which was later amended by PERMA No. 4 of 2019 concerning Small Claims Court. This study aims to examine the mechanism for resolving breach of contract disputes through small claims and its effectiveness in achieving the principles of fast, simple, and low-cost litigation. This research uses a normative legal method to analyze the relevant legal procedures and regulations. The findings show that small claims court is effective in streamlining the litigation process, with a resolution time limit of a maximum of 25 working days, much faster compared to regular litigation, which can take much longer. However, the implementation of this mechanism is limited by the requirement that evidence must be simple, which can be a challenge in some cases. Thus, small claims court can be an efficient and affordable solution for business disputes with low claim values.

Digital images often experience noise disturbances that can reduce visual quality and interfere with the image analysis process. One common type of noise is salt and pepper noise, especially in grayscale images, which is characterized by the random appearance of black and white dots. This study applied the Deep Convolutional Autoencoder (DCAE) method with a skip connection mechanism to eliminate salt and pepper noise in grayscale images measuring 256×256 pixels. The dataset used consists of 300 pairs of clean images and noisy images that have gone through the preprocessing stage, including normalization and data augmentation. The model was trained using an Adam optimizer with a Mean Squared Error (MSE) loss function and validated through a train-test split scheme to avoid overfitting. Model performance was evaluated using Peak Signal-to-Noise Ratio (PSNR) and Structural Similarity Index (SSIM) metrics. The test results showed that the DCAE model with skip connections was able to effectively reduce noise while maintaining the main structure of the image based on the PSNR and SSIM values obtained, and showed better performance than conventional median filters. In addition, the model was successfully implemented into a Streamlit-based application to perform the image denoising process interactively, making it easier for users to experiment and visualize results in real-time.

This study aims to determine how the implementation of the cooperative learning model can contribute to students' cognitive development in Islamic Religious Education (PAI) at SMA Negeri 1 Kasihan.

The study used a qualitative approach with data collection techniques through observation, interviews, and documentation of PAI teachers and grade 11 students. The results showed that the implementation of cooperative learning encouraged students to be more active in discussions, think critically, and understand religious concepts in depth. This model also improved social skills, responsibility, and collaboration among students. Thus, cooperative learning not only strengthens the cognitive domain but also develops students' affective and psychomotor aspects in a balanced manner. These findings demonstrate that cooperative learning is effectively used in PAI learning as an effort to create an interactive, collaborative, and meaningful learning process.

This study addresses low student engagement and high levels of boredom in entrepreneurship courses that rely heavily on one-way PowerPoint-based lectures. Preliminary observations in-dicated that 80% of students experienced low motivation and difficulty generating innovative business ideas. The purpose of this research was to examine the effect of gamification on student learning motivation and business creativity.A quantitative approach was employed using a pre-experimental (One-Group Pretest–Posttest design). The sample consisted of 25 students selected through total sampling. Gamification elements, including: points, badges, and leaderboards, were integrated into the learning process to replace conventional lecture methods.The findings indicate that the implementation of gamification significantly trans-formed student learning behavior and classroom dynamics. Students shifted from passive disengagement, characterized by limited interaction and high distraction levels, to proactive participation. Verbal interactions increased substantially, moving beyond administrative ques-tions toward meaningful business discussions. Students demonstrated heightened engagement and responsiveness during learning activities. The gamified learning environment also fostered a safe space for creative experimentation, enabling students to take entrepreneurial risks without fear of academic or financial failure. Improvements were observed across key di-mensions of business creativity, including fluency, flexibility, originality, and elaboration. The study concludes that gamification is an effective pedagogical strategy for enhancing student motivation and business creativity in entrepreneurship education. By transforming learning from a passive knowledge-transfer model into an experiential and interactive process, gami-fication supports the development of an entrepreneurial mindset among digital native students.

The Payback Period analysis shows that the initial investment can be recovered through cumulative operational cost savings. Environmentally, the implementation of PJUTS significantly contributes to carbon emission reduction and supports the Green Campus vision through the utilization of renewable energy. Overall, the transformation of the existing street lighting system into PJUTS represents a strategic and feasible initiative that fulfills effectiveness, efficiency, and sustainability criteria.

Banks are financial institutions that play a very important role in the economy and continue to innovate by developing various new forms and services. Spin-offs of Sharia Business Units (UUS) are a new method in the world of Islamic banking with the aim of becoming independent Islamic banks in conducting business activities based on sharia principles. The spin-off of the SBU is one of the main focuses of Law Number 4 of 2023 concerning the Development and Strengthening of the Financial Sector. Furthermore, referring to the provisions in Financial Services Authority Regulation Number 12 of 2023 concerning Sharia Business Units, conventional banks can carry out banking activities in accordance with sharia principles by being required to open an SBU. This shows that the UUS is a unit that remains part of the conventional bank, and the provisions governing its activities, even though they are carried out by conventional banks, must still follow sharia principles, including prohibiting interest-based transactions. This study shows that spin-offs of UUS have great potential to drive the growth of Islamic banking. A spin-off is a company's decision to restructure, which has various legal implications. Although spin-offs of Islamic banks have the potential to improve the performance of Islamic banking, government policies that require spin-offs without considering the specific context of each bank can hinder the development of this sector. The implementation of mandatory spin-off policies needs to be balanced with more comprehensive government policy support.

This study analyzes the cinematography strategies in determining creative visuals in the documentary film "2000 for Parking: The Phenomenon of Illegal Parking Attendants in Jatinangor," which documents the practice of illegal parking for Rp2,000-Rp5,000 in the Sumedang educational area as a social critique of the weak supervision of public spaces. Using a descriptive qualitative approach with frame-by-frame content analysis based on Joseph V. Mascelli's 5Cs theory and Bill Nichols' expository mode, the results demonstrate the dominance of eye-level angles (65%), low-key natural lighting (70%), handheld shaky camera (40%), and match cuts to build empathy, urgency, and a persuasive three-act narrative about the phenomenon of urban poverty. This visual strategy represents a power imbalance through low angles and rack focus, resulting in a 40% increase in audience awareness based on test screenings. Budget limitations are overcome through authentic improvisation that distinguishes the film from conventional Indonesian documentaries. The study concludes that cinematography is an effective visual storyteller for social advocacy, suggesting the integration of VR and AI-assisted techniques for future productions.
