This article analyzes the fundamental differences between the mechanisms of fund collection and fund distribution in Islamic banks and conventional banks in Indonesia, based on DSN-MUI Fatwas and banking regulations. In general, both types of banks serve the same function—to collect and distribute funds to support economic activities. However, the main distinction lies in their operational principles. Conventional banks operate using a fixed interest system, establishing a creditor–debtor relationship. In contrast, Islamic banks operate based on Sharia principles that prohibit riba (usury). In fund collection, conventional banks use interest-based savings and deposit products, while Islamic banks apply Wadiah (safekeeping) and Mudharabah (profit-sharing investment) contracts. Regarding fund distribution, conventional banks provide interest-bearing loans, whereas Islamic banks offer financing through Sharia contracts such as Murabahah (cost-plus sale), Musyarakah (partnership), Mudharabah (profit-sharing), and Ijarah (leasing), emphasizing cooperation and risk-sharing. Although Islamic banking is regulated under Law No. 21 of 2008 and DSN-MUI Fatwas, it still faces several challenges, including the dominance of Murabahah financing and the low level of public literacy regarding Islamic financial systems.

This article explores the concept of sets in mathematics, a fundamental foundation for various disciplines. The discussion includes the definition of a set as a well-defined collection of objects, as well as various methods of presenting them such as enumeration, description of properties, set-forming notation, and Venn diagrams. In addition, the article outlines the various types of sets (empty, universe, equal, part, disjoint, crossed, equivalent, power) and explains the fundamental properties of set operations (identity, dominance, complement, idempotent, absorption, commutative, associative, distributive, De Morgan). The primary objective is to provide a concise yet comprehensive understanding of sets as a foundational pillar of logical and mathematical thinking.

Cultural diversity within the university environment is an inevitable reality, particularly within student organizations. The Student Association of the Islamic Communication and Broadcasting Study Program (HMPS KPI) at UIN Sultan Maulana Hasanuddin Banten is composed of students from various regions, each bringing distinct cultural backgrounds, languages, values, and communication styles. This study aims to examine the extent to which cultural differences influence social interaction among members of the organization, as well as how they build harmonious communication amidst these differences. The research employs a descriptive qualitative approach, using in-depth interviews, participatory observation, and documentation with active members of HMPS KPI from various academic cohorts. The findings indicate that cultural differences affect communication styles, expression of ideas, decision-making processes, and perceptions of leadership structures. While such differences may sometimes lead to misunderstandings, they also serve as a strength in fostering an inclusive, open, and adaptive organizational atmosphere that welcomes diverse perspectives. In conclusion, cultural differences significantly influence social interactions within student organizations, but these challenges can be effectively managed through inclusive communication and cross-cultural understanding.

This research uses a quantitative approach with the help of Python to solve infimum and supremum problems involving measurements, calculations and data analysis to draw conclusions. This research process consists of several stages: problem identification, modeling a set of numbers or functions, and implementing algorithms in Python to calculate the infimum and supremum. The calculation results are compared with manual analytical solutions to ensure accuracy and efficient use of Python. Sets as a basic concept in programming allow organizing data and logical operations more efficiently. These findings show that Python is not only effective in calculating supremum and infimum, but also speeds up the solution process compared to manual methods. The results of the program execution show that the analyzed set has an infimum fan supremum which is in accordance with the theory, where set 1 has an infimum of 2, set 2 has a supremum of 5, and set 3 has an infimum of 1 and a supremum of 4.

The bank is an official state institution in the financial sector that has the task of withdrawing and disbursing public money. Banks are one type of trusted institution among the surrounding community. Banks that have a non-trivial task make the bank also registered in the law for its security. There are many banks in Indonesia, one of which is BSI. BSI is the only bank that applies sharia principles based on the Koran and hadith. The existence of these principles makes Islamic banks not carelessly choose transactions or cooperation with other parties or customers. Uniquely, Islamic banks also use a profit sharing system as their ratio. Whereas conventional banks use the deposit interest system as their ratio. That is why researchers are interested in conducting research on the difference between the principles of Islamic banks and conventional banks in fundraising products (funding). There are three types of fundraising products in both Islamic and conventional banks, namely checking accounts, savings accounts and time deposit accounts. The difference is that Islamic banks use wadi'ah contracts and mudharabah contracts. This study aims to introduce to all people that Islamic banks have their own uniqueness and characteristics. Therefore, it is necessary to explain the contracts involved in Islamic banking. In this study, researchers used qualitative techniques. There are two data sources: Primary and secondary data sources. The researchers conducted direct interviews with informants based on primary data.
