This research is motivated by an analysis of the need for a health service information system which is an important part that cannot be separated from the health system in a country. This study aims to provide fast service information to the public and can increase the role of health care institutions through the provision of information about health complaints that occur in the surrounding environment. Especially in the era of the industrial revolution 4.0 which is also known as the digital era, where many sectors of life are inseparable from the participation and use of computer technology. Community Health Centres (Puskesmas) is one of the health service centers at the sub-district level. The number of patients is quite large, causing problems in getting information about the patient, the number of patients, the number of visits, total income, data on drug supply and drug data that has been used by the puskesmas. Based on the existing problems, it is necessary to design a web-based health service information system using the PHP and HTML programming languages and MySQL as its storage media or database. The system development methodology that I use is the prototype methodology. The result of the development of the system is that the system can help the Public Health Service Center to manage existing health services, especially helping the community to obtain important information about health services.

The Faculty of Computer Science, Dharmas University Indonesia must have adequate laboratory facilities, this is because the Departments in the Faculty of Computer Science are 60% practice and 40% theory. Currently the facilities owned by this Faculty are quite adequate but administratively they are still not supportive. One of them is the process of borrowing computers, scheduling practices, and processing Inventory data which is still conventional, which is done by recording on a ledger and a piece of paper. If this continues, it is likely that data will easily be lost in the administration of documents and goods data that is not neat. In addition, officers will find it difficult to determine the scheduling of practicum courses. To solve these problems, a web-based laboratory Management Information System was designed to make it easier for workforce officers and lecturers to carry out learning activities and borrow practicum tools. The Waterfall method is used to build this system. The results of the research are web products built using PHP MySQL. Through this system the performance of officers is increasing because officers can manage inventory data, information on incoming and outgoing goods, scheduling courses, borrowing computer workforce facilities easily and quickly.

Develop an expert system as supporting legacy property distribution of decision which based on the Islamic law. This expert system expected can help everyone who need distribution value of legacy property by using distribution method based on the Islamic law. The legacy property value which will be distributed is legacy property after taken by the will if it was. And debt, corpse of administration cost. The distribution result is an percentage value for each heir who have right to get the property legacy after distribution process. Determination of nominal value of legacy property will not be count in this system. The user system can obtain nominal value of distribution property by multiplying the distribution percentage with whole value of legacy property. The result that taken form this expert system is output as information of heir group who has right to the legacy, and percentage value for each heir who has right to get the legacy. The inference method that used in this expert system is Forward Chaining Method. The method that used for system analysis and designing is Data Flow Oriented method by using Data Flow Diagram (DFD) tool. The database design is using Entity-Relationship Diagram (E-R Diagram) relation model.

The Office of the Ministry of Religion is one of the Government Agencies that has inaugurated the One-Stop Integrated Service. In a one-stop integrated service already using a computer as a data processing device, but based on observations of researchers the Office of the Ministry of Religion applies a queuing system manually where registration officials call verbally, so visitors want to overtake each other and inconvenience and lack of discipline is queued. And observations from researchers of the system are ineffective and cause complaints from visitors. To improve the quality of service to visitors, a desktop-based Queue Information System application is created using the java programming language. This program is expected to help improve services so as to create optimal service.
