01 — Overview

Project Overview

Aplikasi Gaji Karyawan is an interactive desktop application developed to streamline employee payroll administration. Built using Java and MySQL with a Java Swing graphical user interface, the system eliminates manual salary calculation errors by automatically computing base salaries, overtime rates, allowances, and deductions while maintaining a persistent payroll history.

02 — Problem

The Challenge

Manual payroll calculations using spreadsheets or paper records are prone to human errors, delays in salary slip generation, and inconsistent employee attendance and deduction tracking.

03 — Solution

Engineering Approach

An integrated desktop application featuring employee master data management, automated net salary calculations (base pay, allowances, overtime, and deductions), role-based user authentication, and comprehensive payslip archiving backed by a relational MySQL database.

04 — Deliverables

Key Features

  • Employee master data management (CRUD operations via GUI)
  • Automated net salary calculation with custom allowances and deductions
  • Overtime pay and bonus computation engine
  • Historical payslip record keeping and searchable transaction archives
