Abstract

Urbanization and population growth present significant challenges for efficient and sustainable waste management. This research develops an IoT-based intelligent system for waste classification and management utilizing RFID technology, ESP32, a camera, an ultrasonic sensor, and the YOLOv11 object detection model. The system accurately identifies three categories of waste: organic, inorganic, and hazardous. The classification process is automated, incorporating user identification via RFID, servo-controlled bin lid operation, and capacity monitoring through an ultrasonic sensor. Data management is facilitated through a mobile application and a website, which provide user guidance and support for administrators. Test results indicate that the system achieves an average accuracy of 87.5% in the mAP50-95 evaluation, with specific accuracies of 89.0% for inorganic waste, 86.0% for hazardous waste, and 87.0% for organic waste. Despite these results, challenges remain, including object detection errors related to background interference. Future research should focus on enhancing the dataset and implementing data encryption to improve model accuracy and information security. This system demonstrates significant potential for enhancing waste management efficiency and promoting sustainable environmental practices.

Abstract

AbstrakPenelitian ini bertujuan untuk meningkatkan kualitas kebersihan kelas di lingkungan sekolah melalui implementasi website interaktif. Kebersihan kelas yang sering terabaikan memiliki dampak signifikan terhadap kesehatan dan konsentrasi siswa, sehingga mempengaruhi efektivitas pembelajaran. Oleh karena itu, penelitian ini mengembangkan sebuah website menggunakan model pengembangan interaktif Waterfall yang meliputi tahapan analisis kebutuhan, desan sistem, implementasi, danpengujian. Website ini dirancang untuk memudahkan penjadwalan piket, memberikan informasi kegiatan, dan memotivasau siswa melalui fitur Leaderboard. Implementasi menggunakan framework Laravel memastikan struktur yang kokoh dan fleksibel. Pengujian dengan metode Blackbox menunjukkan bahwa setiap fitur berfungsi dengan baik, meskipun perlu pengujian lebih lanjut dengan lebih banyak pengguna. Hasil penelitian ini diharapkan dapat memberikan solusi inovatif untuk mengatasi masalah kebersihan di sekolah, meningkatkan kesejahteraan siswa, dan mendukung proses pembelajaran yang lebih efektif.

Abstract

Secure data communication is an essential requirement in the digital age, especially in the exchange of confidential information. One of the main problems is the potential for eavesdropping by unauthorised parties who can access open messages. To overcome this, this research aims to develop a website-based system that combines the Least Significant Bit (LSB) method steganography technique and the Caesar cipher method cryptography with the Dvorak keyboard layout to increase data security. The research method used is prototype method with the stages of concept formulation, prototype design, and continuous evaluation. The system was tested by inserting the word ‘TEKKOM’ into a digital image and measuring the quality using Mean Squared Error (MSE) and Peak Signal-to-Noise Ratio (PSNR). The test results show an MSE value of 0.0001466049 and PSNR of 86.47 dB, which means that the visual quality of the image does not decrease significantly and the message is successfully inserted and extracted without errors. The Dvorak keyboard layout adds a layer of security through uncommon input patterns, making it difficult for outsiders to analyse. Thus, the system is able to provide a secure, efficient, and practical solution for web-based information hiding without the need for a database and is still user-friendly.Keywords: Dvorak, Steganography, Caesar Cipher, Least Significant Bit, Website
