Abstract

Database is a fundamental component of an information system, where its development or use must be viewed from a broader perspective based on the needs of the organization. With the database all work becomes easier, both in data processing and viewing the output of the data. However, in addition to this convenience, it takes the security side of each record in the database to maintain data confidentiality. Implementation of Classical Cryptography in database security is made using the PHP Programming Language and MySQL Database. The classical cryptographic algorithm applied in this study is the Railfence Ciper Algorithm. Applications and application databases are uploaded online through the hosting domain https://kriptografihidayat.my.id/ and can be accessed from anywhere and anytime via the internet. Based on the tests that have been carried out, the results show that the application is able to secure the employee database in each storage field, and the functionality of the application runs as expected. The key used cannot be changed dynamically, but can be changed statically because it has been integrated into the program code to perform encryption and decryption on each input field. Record Table in the employee database that has been encrypted using the Railfence Ciper algorithm, so it cannot be read. Wireshark managed to capture the packet, but it was detected that there was an encryption process going on.

Abstract

This study aims to create an expert system application to diagnose periodontal disease in humans using the Certainty Factor Method. Periodontal is a dental disease that causes tooth loss due to inflammation from bacteria that results in progressive damage to the supporting tissues of the teeth. The problem that often occurs is the lack of knowledge and limited sources of information causing low public awareness of efforts to prevent and even treat dental and oral diseases. The MySQL database can accommodate patient information and data who consult with an expert system that can provide convenience for patients to consult about periodontal disease. From the results of the system program on the users, it was found that the average results of respondents' answers which reached 53% answered strongly agree, 26% answered agree, 14% answered less agree and only 7% of respondents answered disagreed. So from the results of data processing, it can be concluded that this system is feasible to use. Because more than half of the respondents agree that this system is suitable to use.

Abstract

Ummi shop is a company engaged in the sale of traditional cakes. The sales system used today is a conventional system, where the buyer must come directly to the Garsel Shop to see the products offered. With this system, it will take the consumer's time so that it is difficult to obtain information about the specifications of the product being offered. E-Commerce or in Indonesian, namely electronic commerce is the distribution, purchase, sale, marketing of goods and services through electronic systems such as the internet or television, www, or other computer networks. E-commerce can involve electronic funds transfer, electronic data exchange, automated inventory management systems, and automated data collection systems. At this time, Ummi Store has not used the e-commerce facility so that it is difficult to offer products to consumers who are outside the city. In addition, it can also have an impact that affects the product sales process, namely the ignorance of consumers who are outside the city of the existence of Ummi Shops. The process of selling the Ummi Store will only be carried out if there are consumers who come to the store, while many consumers who are outside the city cannot come or do not know the existence of the Ummi Store. To build this e-commerce system, the tools used to describe the system model are in the form of a data flow diagram (FlowMap), context diagrams, and Data Flow Diagrams (DFD), as well as in database design using a data dictionary and Entity Relationship Diagram (ERD). With the existence of e-commerce is expected to make it easier for consumers to obtain information about product specifications offered by Ummi Stores. Make it easy for Ummi shops to offer or sell their products to consumers who are outside the city. Consumers who are outside the city can find out the existence of Ummi stores by using this e-commerce service and can order without having to come to the store. Make it easy for consumers to process payments because there are several options in the payment process. With a good product data processing or management system that is equipped with security, it will support the performance of the system.

Abstract

Masalah Internet merupakan salah satu hasil dari kecanggihan dan kemajuan ilmu pengetahuan dan teknologi buatan manusia. Internet adalah singkatan dari Interconnected Networking yang apabila diartikan dalam Bahasa Indonesia berarti rangkaian komputer yang terhubung di dalam beberapa rangkaian jaringan. Allan (2005) berpendapat bahwa “Internet merupakan sekumpulan jaringan computer yang saling terhubung satu sama lain secara fisik dan juga memiliki kemampuan untuk membaca dan menguraikan berbagai protocol komunikasi tertentu yang sering kita kenal dengan istilah Internet Protocol (IP) serta Transmission Control Protocol (TCP)..”Perilaku kita ber-Internet berkaitan langsung dengan sedikit-banyaknya materi negatif yang mengancam kita. Semakin kita waspada dan tidak ceroboh ketika menggunakan Internet, maka akan makin kecil kemungkinan kita, anak, remaja atau anak didik kita terpapar berbagai materi negatif dari Internet. Salah satu langkah antisipasi untuk menangkal materi negatif tersebut adalah dengan menginstal software pengaman di komputer kita. Yang harus diingat adalah, berbagai macam software yang tersedia tidaklah menggantikan peran orang-tua, guru ataupun komunitas dalam memberikan keamanan dan kenyamanan anak, remaja atau anak didik kita selama ber-Internet. Software hanyalah alat bantu, yang tidak bisa menjamin 100% menghalau materi negatif dari Internet.
