Abstract

Household waste classified as Hazardous and Toxic Waste (Bahan Berbahaya dan Beracun—B3) poses serious risks to health and the environment if not managed properly. Mismanagement can result in groundwater contamination, soil degradation, and long-term exposure to carcinogens. To address this issue, TOXMAP was developed as a mobile-based system that integrates real-time image classification with location-based disposal guidance. This paper discusses the development of the TOXMAP backend using a FastAPI server to process image input and classify waste using a pre-trained Support Vector Machine (SVM) model. Firebase supports user authentication, image storage, and retrieval of nearby dropbox locations. The Flutter-based frontend enables cross-platform access and supports real-time camera input. Load and integration tests show that the system responds in under one second with good classification accuracy and high user responsiveness. The system architecture effectively combines machine learning inference, cloud-based data handling, and mobile accessibility. FastAPI, Firebase, and SVM were selected to ensure lightweight, responsive, and accurate performance. Testing confirmed strong system stability and efficient computation during iterative use. The SVM model offers a balance between prediction accuracy and resource efficiency. By providing accurate classification and practical location guidance, the TOXMAP system enhances environmental awareness and promotes responsible disposal behavior. This architecture presents a scalable, lightweight, and accessible solution to support better household hazardous waste management and sustainable behavioral change.

Abstract

The Internet of Things (IoT) has become an important technology in the development of modern access control systems. This study presents the design and implementation of an IoT-based Smart Dorm Key system employing a two-factor authentication mechanism using voice password verification and fingerprint authentication to improve dormitory access security. The proposed system is designed for Telkom University dormitories and enables real-time access control, monitoring, and access log synchronization through internet connectivity. The system utilizes an ESP32 microcontroller as the main controller integrated with an AS608 fingerprint sensor, solenoid door lock, no-touch sensor, LCD display, and buzzer to support authentication and door operation. Voice password verification is performed through a mobile application as the first authentication layer before fingerprint verification is conducted as the second layer. Experimental results show that the fingerprint sensor achieved 100% accuracy under normal conditions, while its performance decreased under wet and dirty finger conditions with accuracy values of 8% and 11%, respectively. The no-touch sensor operated reliably with a maximum detection distance of 10.5 cm. The results indicate that the proposed system is capable of implementing layered authentication and real-time monitoring, although further improvement is required to enhance performance under non-ideal conditions.

Abstract

Kegiatan pengabdian kepada masyarakat ini bertujuan untuk memberikan pelatihan penggunaan Google Drive dan Spreadsheet bagi siswa-siswi SD Sekolah Hamidah Sampurna. Melalui pelatihan ini, peserta akan diperkenalkan pada konsep dasar penyimpanan berbasis cloud, pengelolaan folder dan dokumen, serta pemanfaatan Google Spreadsheet untuk pengolahan data sederhana. Metode kegiatan dilakukan secara praktik langsung dengan pendekatan interaktif, dalam hal ini siswa diberikan kesempatan untuk mencoba mengoperasikan aplikasi secara mandiri dengan bimbingan fasilitator. Hasil yang diharapkan adalah meningkatnya pemahaman dan keterampilan digital siswa, khususnya dalam mengorganisasi dokumen secara rapi, bekerja kolaboratif, dan mengolah data sederhana untuk mendukung kegiatan belajar mereka. Dengan demikian, program ini diharapkan dapat mendukung literasi digital sejak dini, menumbuhkan kemandirian belajar, serta memperkuat kesiapan siswa menghadapi tantangan pendidikan berbasis teknologi di masa depan.

Abstract

Waste is the residual product of human use that is often simply discarded and piled up, including organic household waste. The decomposition of organic waste causes unpleasant odors, environmental pollution, and becomes a breeding ground for disease-carrying animals. Therefore, composting is a necessary method that can be applied in households to manage organic waste with the aim of reducing and transforming it into beneficial products. In this modern era, a more efficient composting tool is needed, utilizing the Internet of Things (IoT) to monitor the composting process in real-time to produce compost that meets the Indonesian National Standard 19-7030-2004. This compost quality monitoring can be conducted both locally and remotely through a website integrated with the NodeMCU ESP32 microcontroller, which is connected to a Wi-Fi network to transmit data in real-time to a MySQL database for storage and management. Website testing at Wi-Fi distances of 5 meters and 10 meters from the device resulted in average response times of 31.943 ms and 31.444 ms, respectively, indicating that the website receives information with very good speed. 99.33% of all respondents agreed that the website met the friendly criteria in terms of both color and layout.
