RANCANG BANGUN SISTEM ABSENSI GURU DAN STAFF BERBASIS WEB MENGGUNAKAN ALGORITMA HAVERSINE

Introduction

Rancang bangun sistem absensi guru dan staff berbasis web menggunakan algoritma haversine. Kembangkan sistem absensi guru & staf berbasis web dengan Haversine & validasi IP. Akurat lokasi, verifikasi jaringan sekolah, tingkatkan keamanan & keandalan absensi.

Abstract

Kehadiran guru dan staf memiliki peran penting dalam menjaga kelancaran kegiatan pendidikan di sekolah. Sistem absensi manual sering menimbulkan masalah seperti keterlambatan pencatatan, ketidaktepatan data, dan potensi kecurangan. Untuk mengatasinya, dikembangkan sistem absensi digital berbasis web dengan validasi lokasi menggunakan algoritma Haversine dan verifikasi jaringan melalui IP address. Algoritma Haversine berfungsi memastikan pengguna berada di area sekolah melalui perhitungan jarak antara koordinat perangkat dan lokasi sekolah. Validasi IP address digunakan untuk memverifikasi koneksi pengguna agar hanya dapat melakukan absensi melalui jaringan resmi sekolah. Sistem ini dibangun menggunakan framework Laravel dan dirancang agar mudah diakses melalui berbagai perangkat. Hasil pengujian menunjukkan sistem mampu mengenali lokasi dan jaringan pengguna secara akurat serta meningkatkan keamanan dan keandalan proses absensi. Kata Kunci: Sistem Absensi, Web, Haversine, Validasi IP Address, Laravel

Review

This paper, titled "RANCANG BANGUN SISTEM ABSENSI GURU DAN STAFF BERBASIS WEB MENGGUNAKAN ALGORITMA HAVERSINE," addresses a pertinent issue in educational institutions: the inefficiencies and vulnerabilities of manual attendance systems. The abstract effectively highlights common problems such as delayed recording, data inaccuracies, and potential for fraud, which can significantly hinder the smooth operation of school activities. By proposing a digital, web-based attendance system, the authors aim to provide a robust solution that enhances the accuracy, reliability, and security of teacher and staff attendance tracking, thereby contributing positively to the administrative efficiency of schools. The methodological approach presented is comprehensive and technically sound, leveraging contemporary web development practices and specific algorithms for enhanced validation. The system is built using the Laravel framework, indicating a modern and scalable web application. A key strength lies in its dual-layer validation mechanism: utilizing the Haversine algorithm to accurately calculate the distance between a user's device coordinates and the school's location, ensuring physical presence within the designated area. Complementing this, IP address validation verifies that attendance can only be submitted through the official school network, significantly mitigating unauthorized access or off-site submissions. This combination of location and network verification provides a strong framework against potential manipulation. The reported outcomes suggest that the developed system successfully addresses the outlined challenges. The abstract states that testing demonstrates the system's capability to accurately recognize both user location and network, leading to improved security and reliability of the attendance process. The design emphasis on accessibility across various devices further enhances its practicality and user-friendliness. Overall, this work presents a well-conceived and implemented solution that stands to offer substantial benefits to schools seeking to modernize and secure their attendance management, paving the way for more efficient and transparent administrative operations.
