Need help that is better than expected, both from the borrower and those who have lending facilities, there are still those who ask for a loan approval letter, the amount of lending data can help redundancies based on room lending information for a long time, the lending process, must be approved by various party. In this research, as a first step in developing the system, a system analysis using the PIECES framework is used as an analysis of the functional requirements of the system to see the weaknesses of conventional old systems compared to new systems using technology. From this analysis the system design is made using UML. Furthermore, the design that has been made will be implemented into the PHP Programming Language.
