The growth of the Islamic economy in Indonesia requires financing instruments that are not only in line with Islamic principles but also capable of driving the real sector productively. Istisna' contracts, which involve the sale of goods by order, offer a promising solution for financing construction projects, manufacturing, and micro-businesses. This study aims to explore the definition, role, and implementation of istisna' contracts in supporting the growth of the Islamic economy. Using a descriptive qualitative method based on literature review and normative-economic approaches, the study finds that istisna' contracts can enhance productivity, create employment opportunities, and support sustainable economic development. However, their implementation still faces challenges such as limited public understanding, financing risks, and a lack of education for business actors. Therefore, efforts to optimize the use of istisna' in Islamic financial institutions are essential

The rapid growth of RT/RW Net-based internet services among the community has driven the need for an integrated, efficient, and easy-to-use billing system. The self-help RT/RW Net model often faces challenges in terms of administrative management, especially related to customer recording, billing, and financial reporting which are still done manually.

The design of banknotes is not merely an aesthetic element but also holds symbolic meanings that reflect a nation's identity, history, and cultural diversity. This study analyzes the design of the 2022 Rupiah banknotes using Charles Sanders Peirce’s semiotic approach, which consists of icons, indexes, and symbols, through a qualitative descriptive method. The findings indicate that the visual elements in these banknotes function not only as a medium of exchange but also as a visual communication tool that strengthens nationalism and cultural awareness. National heroes, traditional dances, indigenous flora, and natural landscapes featured on each denomination carry both explicit and implicit meanings that represent Indonesia's historical and cultural values. Furthermore, the design differences between the 2016 and 2022 emissions, such as the use of more vivid colors, varied sizes, and enhanced security features, highlight the government's visual communication strategy to maintain authenticity and facilitate Rupiah identification. This study provides insights into how banknote design serves as an educational medium and a unifying tool for the nation through meaningful visual symbols.
