Sistem Penghitungan Jumlah Kendaraan Pada Area Parkir Menggunakan Background Subtraction Dan OpenCV

Nando Juliansyah, Wendi Saputra, Febri Dristyan
Abstract: Masalah pengelolaan parkir di Politeknik Jambi sering menyebabkan ketidakefisienan akibat sistem penghitungan manual yang rentan human error. Penelitian ini bertujuan merancang sistem penghitungan kendaraan otomatis berbasis… asis pengolahan citra digital. Metode yang digunakan adalah Background Subtraction dengan algoritma MOG2 dan OpenCV menggunakan video kamera smartphone. Sistem mengintegrasikan proses preprocessing citra, operasi morfologi, dan Euclidean Distance Tracker untuk melacak serta menghitung kendaraan secara real-time. Hasil penelitian menunjukkan sistem mampu membedakan kendaraan yang bergerak dengan objek statis secara akurat melalui Virtual Counting Line. Dengan beban komputasi yang ringan dan biaya rendah, sistem ini efektif menjadi solusi otomatisasi manajemen parkir di lingkungan kampus. Parking management issues at Politeknik Jambi often lead to inefficiencies due to manual counting systems prone to human error. This study aims to design an automatic vehicle counting system based on digital image processing. The method utilizes Background Subtraction with the MOG2 algorithm and OpenCV using smartphone video input. The system integrates image preprocessing, morphological operations, and Euclidean Distance Tracker to track and count vehicles in real-time. The results demonstrate that the system can accurately distinguish between moving vehicles and static objects via a Virtual Counting Line. With low computational requirements and cost-effectiveness, this system offers an efficient automation solution for campus parking management.

Abstract: This research examines the application of ethnomathematics in coin exchange activities at Sarwono Market, which is related to learning arithmetic operations, with the aim of understanding how everyday practices in market… transactions can serve as a medium for learning mathematics. The method used in this study is a qualitative approach with an ethnographic perspective, allowing the researcher to observe and understand phenomena within a broader social context. Data collection was carried out through interviews with traders and market visitors, direct observation of the coin exchange activities, and documentation of activities related to these transactions. The collected data were then analyzed using three main stages: data reduction, data presentation, and conclusion drawing. The results of the study show that the practice of coin exchange not only facilitates transactions in the market but also serves as a medium for applying arithmetic operations in everyday life. This activity encourages the development of logical thinking skills, such as addition, subtraction, multiplication, and division, which are frequently used in the bargaining process or in determining the price of goods. Furthermore, coin exchange helps maintain price stability and increases transaction efficiency in the market by reducing dependence on paper money, which is often difficult to divide accurately. Thus, the study concludes that the application of ethnomathematics in coin exchange activities at Sarwono Market provides dual benefits, both in the economic context and in mathematics education.
