Abstract

The development of technology and information today greatly affects data security and privacy. Data, which includes facts or details about an event, can be in various forms and requires reliable management. Cryptography is the main solution to securing information, which involves two main processes: encryption and decryption. The ElGamal method, an asymmetric cryptography algorithm, uses a pair of public and private keys, increasing data security without sharing the secret key. ElGamal's strength lies in the Discrete Logarithm Problem, which provides resistance to brute force attacks. It can also be used for digital signatures, ensuring the authenticity and integrity of dataThe implementation results concluded that ElGamal effectively secures text data by encrypting it into a sequence of unrepresentative characters. This implementation provides an additional layer of security by making the encrypted data unconnected to the original information

Abstract

Abstract: Data and information security and confidentiality are important elements of data and information. A database is a collection of logically related and integrated information that can meet the needs of an organization. Database security is the last line of defense when a system is attacked by an external party after successfully bypassing network defenses, operating system security, and applications. Data security can be protected through the implementation of cryptography. Affine Cipher can make a system feel secure by multiplying each plaintext value by a different number and then adding it to the shift value. From the results of the tests conducted, the contents of the database records are secured, so that the records stored in the database are randomized and the developed application can function as expected. Keywords: Security, Database, Affine Cipher. Abstrak: Keamanan serta kerahasiaan data atau informasi adalah salah satu elemen yang penting dalam sebuah data atau informasi. Basis data merupakan sekumpulan informasi yang saling berhubungan secara logis dan berintegrasi sehingga dapat memenuhi kebutuhan suatu organisasi. Keamanan basis data merupakan benteng terakhir saat suatu sistem diserang oleh pihak luar setelah berhasil melewati pertahanan jaringan, keamanan sistem operasi, dan aplikasi. Keamanan data dapat dilindungi melalui penerapan kriptografi. Affine Cipher dapat membuat sistem terasa aman dengan mengalikan setiap nilai teks biasa dengan angka berbeda dan kemudian menambahkan dengan nilai pergeseran. Dari hasil pengujian yang telah dilakukan mengamankan isi record database, sehingga yang tersimpan di dalam database record yang telah diacak dan aplikasi yang dikembangkan dapat bekerja sesuai dengan yang diharapkan. Kata kunci: Keamanan, Database, Affine Cipher

Abstract

Patient satisfaction in healthcare services is very important to pay attention to because it can provide an overview of service quality. Patients will feel satisfied if the healthcare services they receive meet or exceed their expectations, and conversely, patient dissatisfaction or disappointment will arise if the healthcare services they receive do not meet their expectations. KANO is one of the methods used to assess patient satisfaction with service quality and measure service quality by identifying patient preferences and categorizing service attributes. Thus, patient satisfaction is the level of feeling patients experience as a result of the healthcare services they receive after comparing them with their expectations. The system implementation uses PHP programming language, and the method employed in this study is System Development Life Cycle method. From the results of the testing conducted, it can be concluded that patient satisfaction using this method can be achieved effectively and establish high-quality service standards

Abstract

Pneumonia is a serious disease and can threaten human life, pneumonia is most serious when it occurs in infants and children. This study was conducted at the Tebat Karai Health Center, Tebat Karai Sub-district, Kepahiang Regency. Given the large number of patients suffering from pneumonia, sometimes the Tebat Karai Health Center has difficulty in handling it. Therefore, an expert system using the Certainty Factor method was designed. With this expert system, it can provide ease of initial consultation if the doctor is not available, although later it will still be consulted directly with the doctor. This expert system uses the PHP programming language and MySQL database. The resulting expert system can provide convenience for users to diagnose early pneumonia online.
