THE DESIGN OF MANAGEMENT INFORMATION SYSTEMS AT JAMI KAUTSAR MOSQUE

This research is motivated by the management of the Jami Al-Kautsar Mosque in Depok which has not been properly recorded and the data storage is scattered. These constraints have the potential for data loss and inaccurate information and a process taking a long time to produce such information. In this study, the data collection techniques used are observation, interviews and literature study. The information system built uses the waterfall method as a software development or Software Development Life Cycle (SDLC) using object-oriented design of the Unified Modeling Language (UML) and testing using Black Box. The process in this study includes the process of managing activities, managing the mosque, inventory, finances and goods (income and expenditure). The results of research implemented by the author on the Management Information System of the Jami Al-Kautsar Mosque is a system that can provide information on the management of activities, mosque administrators (human resources), inventory, finances and goods (income and expenditure) as well as communicative and informative reports so that they can make evaluation materials and transparent accountability reports from the management to all congregations of the Jami Al-Kautsar Mosque. User satisfaction with the evaluation information system uses the five-category Black Box test and produces a good information system. of


INTRODUCTION
Mosques have meaning in the lives of Muslims, because since the time of the Prophet Muhammad, they have become the main center for all Muslim activities. In fact, the mosque at that time became a facility for Muslims to achieve the advancement of civilization. The function of a mosque in the history of its emergence is not only for "a place of prostration" as its literal meaning, but is multifunctional as a center for educational, political, economic, social and cultural activities [1] [2].
Jami Al-Kautsar Mosque is located at Jl. Mahakam No.51, RT.3, Bakti Jaya, Sukmajaya, Depok City, West Java. The Jami Al-Kautsar Mosque has a large area so that the Jami Al-Kautsar Mosque often facilitates weddings or other activities. The Mosque Prosperity Council (DKM) of the Jami Al-Kautsar Mosque continues to improve its performance through comprehensive coaching in three areas including: management (idarah) to improve the quality of mosque organization by seeing how the mosque is managed professionally in an organized manner, development in the field of prosperity Mosque (imarah) by observing the function of the mosque in the activities of empowering the people, and fostering the maintenance of the mosque (riayah) by seeing how the physical form and infrastructure of the mosque are always properly maintained and improved [3]. Mosque administrators understand that the prosperity of the mosque lies in its empowerment activities, as an effort that must be followed while strengthening the potential or power possessed by each community [3] [4]. Many of the activities carried out by DKM Jami Al-Kautsar are not only religious in nature, so that the mosque administrators often experience difficulties in managing the data management of their activities. Documentation of activities is also not neatly recorded and communication is lacking so that there is often an overlap between one activity and another.
The inventory at the Al-Kautsar Mosque is not neatly recorded, only in the form of scribbles sometimes located in various rooms of the mosque secretariat. Mosque administrators do not often know the mosque inventory that can still be used, lost and lent to the surrounding community. Finances and goods (income and expenditure) occuring at the Jami Al-Kautsar Mosque are currently still using the method of recording in a book (paper based), where every income either in the form of money or goods is only recorded in a book. This has a big potential Hal. 1-8 p-ISSN : 2339-1103 e-ISSN : 2579-4221 2 for miscalculation and loss of the income list if the mosque's entry log is lost.
The mosque management (human resources) at the Jami Al-Kautsar Mosque is also one of the root problems occuring today. The list of mosque administrators is not well recorded and only has a list of the main mosque administrators printed in an organizational chart and only placed at the mosque secretariat. The list of the mosque's congregation is not recorded so that the management does not remember who can be used for activities at the mosque. The responsibility of a job is often delegated to the same people so that there is a lack of equal distribution of work in each administrator or congregation.
Technological updates in the management of the mosque system internally will make the mosque better. In this study, the information system will be built on a web-based basis so that it will make it easier for mosque administrators and congregations to access this information system. In addition to easy access, this information system can help make it easier for mosque administrators to manage data and provide information in a transparent, fast and accurate manner to the public through the information system created.

II. THEORETICAL BASIS 2.1. Information System
Information systems, namely collecting, processing, storing, analyzing, disseminating information for specific purposes. Like other systems, an information system consists of input (data, instructions) and output (reports, calculations). Information systems process input and produce output sent to users or other systems. A reciprocal mechanism controlling operations can be included as well. Like any other system, an information system operates in an environment. In studying information systems, it is necessary to know about the differences in data, information, and knowledge [7] [9] [10].

Management
Management comes from the word to manage meaning to organize. In regulating matters, problems, processes and questions will arise about what is regulated, who regulates, why should it be regulated and what is the purpose of the arrangement. Management also analyzes, sets goals / objectives and determines tasks and obligations properly [8].

Definition of a mosque
Estimologically, a mosque is a place to prostrate, in the framework of worshiping Allah SWT or a place to offer prayers. Meanwhile, sociologically the mosque developing in Islamic society in Indonesia is a certain place or building intended for Muslims to pray, consisting of obligatory prayers and sunnah prayers, either individually or in congregation.
Basically, mosque is not only used as places of worship, but mosque also plays a role as a center for community and Muslim community activities including coaching, education, learning, community empowerment, and big day celebration activities.
Strengthening the capacity of administrators in mosques is divided into three areas, namely [6] -The field of organizational management (Idarah). The developments are: • Idaratu binail maddiyyi, physical management including structural management, development arrangements, guarding of honor, cleanliness, order, beauty, maintenance of order, peace, financial and administrative arrangements, and maintenance of the attractiveness of the mosque in inviting worshipers to come. • Idaratu binair ruhiyyi, including the regulation of the implementation of the function of the mosque as a place or forum for community guidance, as a center for community development through education and teaching (majlis taklim). • Mosque prosperity management (imarah) • Facility and infrastructure management (ri'ayah)

Basic Inventory Concepts
Assets in a company are of two types: current assets and fixed assets. Current assets are company assets having a useful life of less than one year. Meanwhile, fixed assets are company assets having a useful life of more than one year [13].

III. RESEARCH METHOD
This study uses the following methods: waterfall, observation, interviews, literature study and Black-Box Testing. The system design is based on data obtained from observations, interviews and literature studies. The author directly observes the input process and activity data management, mosque management, inventory, finances and goods (income and expenditure). The weterfall method is a software development carried out by research stages, namely: -Analysis -Design -Encoding -Testing -Implementation [5] [11] [14].
Black-Box Testing is a software testing technique focusing on the functional specifications of the software. Blackbox Testing works by ignoring the control structure so that attention is focused on domain information. Blackbox Testing allows software developers to create a set of input conditions that will train all the functional requirements of a program [12].

IV. RESULTS AND DISCUSSION
At this stage the researchers discuss the design of the Jami Al-Kautsar Mosque Management Information System starting from system modeling and implementation.

System Modeling
