Abstract

The existence of the Employee Payroll Information System at the Manunggal Village Office provides convenience to its users. The procedure used is simpler so that the Payroll Information System at the Manunggal Village Head Office is more efficient and effective. Therefore, the author designed a Payroll Information System at the Manunggal Village Head Office using Microsoft Visual Basic 2010 software and MY SQL as the database. This research is a research and development research with development and implementation methods. Data obtained through literature study and interviews. The system development method used is an output, process and data oriented methodology. The design of information systems is a context diagram, and data flow diagrams. By implementing the Payroll Information System at the Manunggal Village Head Office, it can make it easier when reporting and in making reports that are processed quickly and well. The application of the Payroll Information System at the Manunggal Village Head Office using Visual Basic 2010 can help performance in the Manunggal Village Head Office.

Abstract

Utilization of Information Technology (IT) now plays an essential role in the success of an organization's business. By storing information digitally, a company is able to access customer information and process orders quickly. A doctor can immediately give action to the patient after accessing the patient's complete medical record without having to disassemble the paper archives stored in the hospital. This can be done thanks to the existence of a computer-based system that is used to process information, specifically the Management Information System (MIS). Imelda Pekerja Indonesia Hospital is a Type B referral hospital in the city of Medan, North Sumatra, where it often happens that patients are unable to make payments after treatment, both outpatient and inpatient, especially patients who pay for themselves, where every patient who is unable to pay, this is The author makes a patient receivables payment system. Management utilizes the PHP programming language and MySQL database where the patient's receivable data has been recorded by the computer as well as the patient's receivable payment validation process, as for some of the features that exist in this patient receivables information system where patient data input can be done and record of patient receivables.

Abstract

This study presents a layered data-security design that combines Affine Cipher encryption with Pixel Value Differencing (PVD) image steganography. The first layer transforms plaintext into ciphertext using a monoalphabetic affine transformation, while the second layer conceals the ciphertext in neighboring image pixels according to local pixel differences. The method is reconstructed as a consistent Affine-PVD workflow and verified through deterministic worked examples rather than unsupported attack-success claims. Using the uppercase alphabet with keys a = 5 and b = 8, the plaintext “DATA” is transformed into “XIZI” and correctly recovered with the modular inverse. In the PVD verification, the pixel pair (100, 108) embeds the three-bit sequence 101 by changing the difference from 8 to 13, producing a valid modified pair (98, 111); extraction recovers the same bit sequence. These results confirm algorithmic reversibility of the two stages. The combined approach provides confidentiality and concealment as separate layers, but Affine Cipher remains a classical cipher and PVD is susceptible to steganalysis. Therefore, the design is appropriate as a prototype or instructional security model rather than a substitute for modern cryptographic protection.

Abstract

Drug Inventory Information System at Royal Prima Hospital Medan. The purpose of making this final project is to be able to assist agencies in finding drugs available at RSU Royal Prima Medan computerized or using a system, designing a system so that the drug search process can be easily found by employees of RSU Royal Prima. The data collection methods carried out by the author include the field method and the average method. The Drug Inventory Information System at Royal Prima Hospital uses VB.Net 2010 programming and MySQL as the database.

Abstract

Computers are very well known and have been widely used by the public. Even with a computer system, this can complete all the work that has been done manually. With the help of computers the work can be completed quickly and structured. Computers are tools that are very popular today in solving problems that are used in various fields of science and information technology. With the development of this information technology, an Advocacy Information System and KIE (Information and Education Communication) at the North Sumatra BKKBN were made on a Web-based basis by creating a database to obtain information which is still being done manually. The Advocacy Information System and KIE (Information and Education Communication) at the North Sumatra BKKBN can be done using several programming languages including mysql. The ability to process data is very important for the Web-based Advocacy Information System and KIE (Information and Educational Communication) at the North Sumatra BKKBN which is engaged in information and moderator. The Advocacy Information System and IEC (Information and Education Communication) at the North Sumatra BKKBN still uses manual work so it requires changes that help researchers to complete work effectively and efficiently. That's why the author made a Web program that serves to provide information to the public about family planning that has been established, to make it easier for people to get information about family planning.
