Halal dalam Konsepsi Alquran dan Penerapannya pada Industri Ikan Salai Patin Desa Wisata Kampung Patin Koto Masjid Kabupaten Kampar

This article seeks to explore the application of the halal industry in the production of Salai Patin fish in the Kampung Patin Koto Masjid Tourism village, Kampar Regency. Many factors can influence the successful implementation of the halal industry, including understanding the concept of halal, the urgent need to develop the Islamic economy, and the profile of Kampung Patin Tourism Village as the center of Patin Fish production. The process of implementing the halal industry begins with awareness and training. Ensuring that catfish business actors understand the sharia principles underlying halal products. Halal certification is an important step to convince consumers that Salai Patin fish products meet the standards of purity and halalness. Collaboration with halal certification bodies and authorized government agencies is also a key factor in maintaining product integrity and quality. The prospect of the halal industry promises sustainable economic growth in Kampung Patin Tourism Village, with the expectation that salai patin fish products can present wider business opportunities, both in local and international markets. This development will support the increasingly globalized idea of sharia economy, changing people's perception of Islam as a religion that is rahmatan lil alamin.

Equilibrium Problems and Their Applications

The abstract theory of equilibrium problems has found its applications in various branches of nonlinear sciences. It provides us a unified structure to study an extensive number of linear and nonlinear physical problems. Since the projection method cannot be used to solve equilibrium problems, so we use auxiliary principle technique to solve equilibrium problems. Our main focus is to apply this technique to suggest several iterative algorithms (implicit and explicit) for solving different classes of equilibrium problems and their variant forms. Some other algorithms are suggested using the combination of auxiliary principle technique and so-called Bregman function. We also study the convergence analysis of these methods. We also consider and analyze a class of regularized mixed quasi variational inequalities. The auxiliary principle technique is again used to suggest some new iterative methods for solving the mixed quasi variational inequalities involving the skew symmetric bifunction. The convergence criterion of these iterative methods for solving the mixed quasi variational inequalities is considered under suitable conditions. Several special cases of these problems are considered. Results proved in this thesis continue to hold for known and new classes of equilibrium problems.
