Full text linkRegistration services for outpatients that are simple and fast are one of the efforts to improve the quality of service to patients who will seek treatment at the hospital. The strategy adopted by the hospital is to utilize information technology to support services, especially the flow of outpatient registration which will later affect patient satisfaction. One of the strategies implemented by hospitals in the current digital era is to implement a computer-based registration system, but in practice there are still many obstacles and the use of the information system is not optimal where there are still many queues and buildup of patients seeking treatment. This study aims to develop an online outpatient booking application that will make it easier for patients to register for outpatient treatment online. This application is expected to make it easy for patients to register outpatient care without having to come directly to the hospital directly. Patients only need to book a polyclinic through the application and check in when they come to the hospital to get a queue number at the intended polyclinic. It is hoped that this application will shorten service time and reduce patient queues

Penerapan Enkripsi Menggunakan Metode Elgamal guna Meningkatkan Keamanan Data
Full text linkData security is very important in maintaining the confidentiality of information, especially those containing sensitive information whose contents should only be known by the entitled people. especially if the transmission is done through a public network, if the data is not secured beforehand, it will be very easy to be intercepted and the contents of the information known by irresponsible people. One of the methods used to secure data is to use a cryptographic system, namely by providing the information content (plaintext) into content that is not understood through the encryption process, and to retrieve the original information, a description process is carried out, accompanied by using the correct key. Therefore, the author recommends the Elgamal algorithm to be able to provide security for text data. The reason the author uses the ElGamal algorithm is that the ElGamal algorithm is part of asymmetric cryptography where the formation of one of the keys uses prime numbers and focuses on the strength of the key in solving discrete logarithm problems
