Sugina . — 2024-12-31

PT. Industri Keramik Angsa Daya (IKAD) is one of the companies engaged in the ceramic industry, which comprises several divisions, one of which is Kopkar Kesetiaan (Employee Cooperative of Kesetiaan). The cooperative within a company greatly benefits employees by providing services such as secure money storage, savings and loans, and other financial needs, thereby simplifying the management of employee finances. However, currently, the cooperative department still handles savings and loans applications manually using paper forms; loan applications are recorded on paper in ledger books and later entered into an Excel file, resulting in delays in generating management reports on savings and loans. Therefore, a web-based savings and loans information system is needed to streamline the application process and enable periodic reporting by leveraging the growing capabilities of the internet.

Moestafa Kemal Pasha — 2024-12-31

Security is a very important aspect for the exchange of data on a website. To maintain the security and privacy of website data, it is necessary to have a data encryption method used to hide information from third parties. One of method that is quite reliable in securing real-time data transmission from packet sniffing attacks is the Secure Socket Layer (SSL) protocol. The research was conducted by analyzing before and after implementing the Secure Socket Layer (SSL) protocol security on the website using application named Wireshark. The results of this research are captures that are analyzed and compared to the results of the analysis, so that it can be concluded that the news website before the SSL protocol security was implemented was very vulnerable to packet sniffing attacks and the results of the capture after it was implemented.

DESIGN AND DEVELOPMENT OF AN ENCRYPTION AND DECRYPTION APPLICATION FOR THE SQL PERMIKOMAS DATABASE USING THE BLOWFISH ALGORITHM

Ardi Juliardi — 2024-12-31

To protect the data or information stored in an SQL database, encryption is used. There are many encryption algorithms available, one of which is the Blowfish algorithm. The Blowfish algorithm is a modern symmetric key block cipher. Encryption is performed using a specific key, which produces ciphertext that is unreadable. This ciphertext can be reverted to its original form if decrypted using the same key. The Blowfish algorithm operates through 16 rounds and takes an input of 448 bits. This 448-bit data is divided into two parts, XL and XR, each consisting of 224 bits. Next, the operations XL = XL XOR Pi and XR = F(XL) XOR XR are performed, and then XL and XR are swapped; this process is repeated 16 times. In the 17th round, the operations XR = XR XOR P17 and XL = XL XOR P18 are carried out, and finally, XL and XR are combined back into 448 bits to produce the ciphertext. By using the Blowfish algorithm, the data in the SQL database—including the database itself, tables, fields, and records—remains unreadable due to encryption, so that only authorized users can access the contents by decrypting it.
