Abstract

The limitations of humans to maintain the security and confidentiality of stored data can have a bad impact if it is used by unauthorized parties. One way to secure shipping is to convert data into one that is not understood by encoding and insertion using cryptographic techniques. Cryptography is the study of system security, where the system needs to be secured from interference or threats from irresponsible parties. One of the cryptographic algorithms is the Blowfish Algorithm. The Blowfish algorithm is a modern cryptographic algorithm symmetrical key shaped block cipher. The Blowfish algorithm is quite simple but strong enough because it has a long key space, making it difficult to attack. Encryption is done by using a certain key, so as to produce ciphertext (files that have been encrypted or encoded) that cannot be read or understood. The ciphertext can be restored as if it was decrypted using the same key when encrypting the file. The key length used can affect the security of the algorithm. The decryption flow is almost the same as the Blowfish Algorithm encryption, except in the P-array (P1, P2, …… .., P18) done by invading. Information of a system is certainly stored in a database that is always possible to attack, but using cryptography then the problem can be overcome. By using the Blowfish algorithm, information security in a MySQL database can be improved.

Abstract

Palang Merah Indonesia (PMI) is an independent and neutral organization in Indonesia whose activities are in the social field of humanity. PMI Medan City is overwhelmed by managing data on blood receipts from various places, this causes delays in information that should be informed to the public, the delay in disseminating information about blood stocks can have an impact on the difficulty of getting information on certain types of blood needs. The blood supply in PMI will later be distributed to the hospital. Many hospitals often have difficulty getting information or lack of public knowledge about how to obtain information about the availability of blood stock at PMI. Therefore we need an information system that can provide information quickly, well and accurately. To overcome this, a system will be developed that uses the concept of Supply Chain Management to control the blood supply in PMI. This system can control the blood donation process both during donation, the donation process, and finally for whom the blood is donated so that the blood stock information process can be maintained and will not lack.

Abstract

Technology has an important role in the implementation of human activities at this time, including in business activities. Today's technology is widely used to manage business activities with various forms of display/templates that are easy to use.Dashboards are used to display data concisely. Reports can be viewed quickly through a summary of the data displayed on the dashboard. So much data processing makes business activities that still carry out manual recording and see the report data sequence is felt to be less effective. Utilization of technology is highly needed by owners of small businesses when facing business management constraints such as a long time to manage data, loss of sales data, purchases and reports recapitulation errors. Besides, the need for fast and accurate data and information access is also needed to support and monitor business management. Based on these problems, a solution is needed to manage the overall sales and purchasing data, and display reports quickly and accurately by carrying out a study entitled "Dashboard Management of Sales and Purchases of Fish in Fish Spots".
