Along with the development of technology, almost all activities that require knowledge of information systems, including health services. Health services to support the process of technological advancement, namely medical records. To support these technological advances, electronic medical records are needed. In the electronic medical record, a technique and method is needed to maintain the security of the system in the electronic medical record. This research was conducted by literature study method. Eleven articles were found that matched the inclusion and exclusion criteria. The selection was taken with the PICOS framework, then the articles were analyzed one by one. There are several techniques and methods that can protect the privacy system in electronic medical records, namely the mIBE, AES, DES, RC4, and RSA methods. As well as techniques such as Cryptography, Firewall, Cloud Computing, Client-Server, and Access Control. The results of the literature review show that the safest technique to use is the cryptographic technique, because the technique is standardized, can be used without limits and the cost is low. And the safest method used for electronic medical records is mIBE-AES because this technique has been proven safe and fast for storing medical record documents.

Along with the development of technology, computerized systems are needed in the business world. The computer has a function as a data processing tool that will assist in completing work quickly and precisely. MA Nurul Ulum as an educational institution, especially in the implementation of payment administration activities, still uses a manual or conventional system, so there are still many shortcomings and obstacles that result in a job not being able to run properly. Therefore we need a new system, namely a computer-based payment administration system in order to be able to manage and process payment data quickly, because with computer technology both students and other parties who want to know information related to tuition payments can get it quickly. The purpose of this study is to improve the quality of service to students or parents in making tuition payments. The advantage of the system that will be made is that it provides an administrative information system for paying school fees so that it can make it easier to perform data processing and data retrieval. With an administrative information system that has been integrated in a database, it will facilitate the process of financial calculations and the existence of a Client Server-based school administrative information system will connect between sections, namely the administrative section, school treasurer, principal and head of the foundation making it easier to access financial information. school any time

Infrastructure is an important thing in an organization/company that is used to support activities carried out within the organization. Infrastructure that includes STMIK Rosma, including hardware, software, data, and information, and human resources that support information systems. Hardware resources include PCs that are used for clients with application program software. Windows 10 professional 32 and 64 bit as the operating system. While the software on the server uses Linux OS and PHP programming language. Data and information include infrastructure data, device data, server data and data on staff, students and lecturers at STMIK Rosma. So the need for the sustainability of this system is increasingly important. Problems that have existed in the STMIK Rosma infrastructure, such as those related to information security vulnerabilities. If this problem cannot be fixed in a sustainable manner, it will have an impact or risk on the sustainability of this infrastructure, especially the academic community. This study uses NIST SP 800-30 as the method used to solve these problems. Keywords: Information Security, NIST SP 800-30, Infrastructure, Risk Assessment

PT. Biru Semesata Abadi is a company engaged in refill drinking water, one of the many drinking water companies in Semarang, and has many branches (10 branches) and one head office in Semarang (in the Bugangan area, East Semarang district), because this company has franchise system. In this case, I will discuss the presence system (presence) of employees of PT. Biru Semesta Abadi, Fatmawati Semarang branch which is still manual (presence made of paper and written by hand) and still encounters many obstacles. This desire arises because this company has difficulties in processing Presence information data, resulting in more and more hardcopy archives and makes it difficult when the company management intends to recap and re-collect data and employee attendance lists. Presence Process that already exists in the Study of PT. Blue Semesta Abadi Semarang can be said that there are still shortcomings because everything is still done manuallyThe use of the Fingerprint method in this employee Presence system application will also make this Presence system more effective and efficient because each employee will only paste one of the employee's fingerprints on the available Fingerprint device where the calculation of the employee's attendance and exit hours will be entered in the database. , then the result of inputting the employee identification number will be the reference for the employee's arrival time.
