Abstract— Klasis GKI Sentani is part of the GKI
Denomination which regulates churches in the Jayapura
(Sentani) Regency area. One of the tasks of the Klasis is the
monitoring and evaluation of the Setoran Wajib Jemaat (SWJ).
Each Church is required to collect offerings cumulatively each
month. The obstacle faced in financial management in the Klasis
Sentani environment is the budget processing system which is
manual, where donations are deposited to Klasis by attaching
proof of deposit. this makes the process of collecting donations an
inefficient routine. Including the documentation process that
looks not up-to-date and the difficulty in publishing the results to
the congregation at Klasis Sentani. This study aims to facilitate
the reporting of mandatory deposits for the classic GKI Sentani
congregation, namely by creating an information system for the
congregation's mandatory deposit. The development of the
software system uses the Waterfall method, with the Unified
Modeling Language as the system modeling language. This
system has been implemented and makes it easier to manage
finances for the church treasurer and classics. Financial
information can also be viewed transparently on the page
provided and can be accessed by the congregation.
