This study examines the potential of productive waqf as an alternative financing mechanism for Micro, Small, and Medium Enterprises (MSMEs) in Indonesia within the framework of Islamic business law. Amid limited access to conventional financing due to administrative and interest-based barriers, productive waqf emerges as a sharia-compliant and socially inclusive solution. Using a qualitative-descriptive method through library research, the study analyzes literature from academic sources and waqf institutions. The findings show that productive waqf not only offers capital assistance but also empowers MSMEs through training, infrastructure, and fair financing schemes. This financing model aligns with Islamic principles such as justice, prohibition of riba and gharar, and public benefit (maslahah). Successful implementations by institutions like Dompet Dhuafa and Bank Wakaf Mikro demonstrate its effectiveness in increasing business capacity, income, and job creation. The study concludes that productive waqf can significantly contribute to sustainable and equitable economic development when supported by strong regulation, professional nazhir management, and broader public awareness.Keywords: Islamic business law, MSMEs, productive waqf, alternative financing, sharia economy

The utilization of drones for mapping is an easy, cheap and fast way with better spatial resolution when compared to conventional mapping or satellite rides. For students of SMK Kehutanan Negeri Pekanbaru, this ability is expected to improve their skills after graduating from forestry school. This service provides solutions including: 1) increase students' understanding of Drone Mapping, 2) increase the competence of SMK Kehutanan Negeri Pekanbaru students in the field of forest and land cover mapping.

In the era of Industry 4.0, optimizing fluid flow systems in smart factories is essential to improve energy efficiency and operational stability. Traditional Computational Fluid Dynamics (CFD) simulations provide accurate fluid flow analysis but require extensive computational resources and long processing times, making real-time applications challenging. To address this limitation, this study aims to develop an AI-based predictive model for CFD simulations, utilizing Convolutional Neural Networks (CNN) and Extreme Gradient Boosting (XGBoost) to accelerate the estimation of fluid flow characteristics in industrial environments. The research methodology involves generating CFD simulation datasets, preprocessing data, and training AI models to predict key fluid parameters such as pressure, velocity, and temperature. The evaluation results show that CNN achieves a Mean Squared Error (MSE) of 0.0025 and a Root Mean Squared Error (RMSE) of 0.05, outperforming XGBoost, which records an MSE of 0.0030 and an RMSE of 0.055. Moreover, CNN predicts fluid dynamics in just 15.2 seconds, while XGBoost achieves results in 10.5 seconds, compared to the 1200.5 seconds required by traditional CFD simulations. These findings highlight the potential of AI in reducing computation time by over 98%, making real-time fluid flow analysis feasible in industrial settings. This study contributes to the advancement of AI-integrated CFD modeling, demonstrating that AI can significantly enhance the efficiency of fluid dynamics analysis without compromising accuracy. Future research should focus on expanding AI models to handle more complex flow conditions and integrating AI with smart factory design tools for real-time optimization

The increase in ornamental fish farming in Indonesia has increased significantly during the 2017-2019 period. This improvement process is certainly faced with various challenges such as disease, which is caused by ectoparasites, one of which is Myxobolus sp. This parasite can infect the skin and gills of fish, causing significant financial losses. This study aims to determine the prevalence and intensity of Myxobolus sp parasites in freshwater ornamental fish at the Surabaya I Fish Quarantine Center for Quality Control and Safety of Fishery Products (BKIPM), which was conducted on June 19 - August 18, 2023. The tools and materials used include fish samples, distilled water, 70% alcohol, giemsa dye, swallow and tissue, tray, binocular microscope, computer, dissecting set, object glass, cover glass, dropper pipette, ruler, gloves, beaker glass, workbook, method, and stationery. Native and staining methods were used to examine parasites, while prevalence and intensity were calculated using Kabata's (1985) formula. The results showed that comet fish and koi fish were infected with Myxobolus sp in their gills. The intensity of Myxobolus sp infection in koi fish was classified as severe, while in comet fish it was classified as very severe. The prevalence of Myxobolus sp parasites found in koi fish was 2.32% and in comet fish was 4.20%, both categorized as moderate infection.
