Abstract

Penelitian ini bertujuan untuk merancang dan membangun sistem keamanan toko berbasis Internet of Things (IoT) yang mampu meningkatkan efektivitas pemantauan dan keamanan toko secara real-time. Sistem ini menggunakan ESP32-CAM sebagai perangkat utama yang terhubung dengan sensor PIR (sebagai pendeteksi gerakan), dua servo motor (untuk mengatur arah pandang kamera), dan Telegram Bot sebagai media notifikasi .Kebaruan (novelty) dari penelitian ini adalah integrasi solusi end-to-end yang low-cost (biaya rendah) antara ESP32-CAM dengan Telegram Bot untuk pengawasan toko skala mikro, di mana keunggulannya terletak pada kecepatan notifikasi real-time dan kemudahan implementasi dibandingkan sistem CCTV konvensional. Sistem dirancang agar dapat mendeteksi gerakan, mengambil gambar, serta menampilkan video livestream melalui web server. Proses komunikasi data antara alamat IP lokal ESP32-CAM dengan server hosting berbasis PHP–MySQL dilakukan menggunakan layanan NGROK (pada fase pengujian awal) atau langsung ke server online. Ketika sensor PIR mendeteksi gerakan, ESP32-CAM secara otomatis mengambil gambar dan mengirimkannya ke server, kemudian sistem mengirimkan notifikasi ke pengguna melalui Telegram dalam bentuk pesan teks dan gambar. Hasil pengujian menunjukkan bahwa sistem beroperasi dengan baik dan stabil, dengan waktu rata-rata dari deteksi gerakan hingga notifikasi diterima di aplikasi Telegram berkisar antara 5–7 detik. Berdasarkan analisis jaringan, rata-rata waktu tunda (delay) pengiriman data berada di kisaran 1–1,2 detik, kecepatan aliran data (throughput) sekitar 310–400 Kbps, dan tidak ditemukan kehilangan paket data (packet loss 0%). Fitur livestreaming video berjalan lancar dengan waktu tunggu stabil 1–2 detik dan kecepatan tampilan mencapai sekitar 10 gambar per detik (10 fps) pada resolusi 320x240 piksel (QVGA). Selain itu, fitur rotasi servo ke arah kiri–kanan dan atas–bawah berfungsi optimal, dengan waktu respon rata-rata 0,8 detik untuk gerakan horizontal dan 1,1 detik untuk gerakan vertikal. Meskipun demikian, sistem ini masih memiliki keterbatasan karena belum dapat menyimpan rekaman video hasil streaming ke server.

Abstract

Oil palm plantations require continuous and reliable monitoring to ensure efficient irrigation, yet many farmers still depend on manual watering methods that are time-consuming and inconsistent. To address this issue, this study develops an Internet of Things (IoT)-based irrigation monitoring system using the MQTT communication protocol to support real-time data delivery and automated control. The system integrates ESP32 microcontrollers, soil moisture and environmental sensors, HiveMQ Cloud as the MQTT broker, and Telegram Bot notifications. The research was conducted on a 27 m × 70 m oil palm plantation consisting of 24 trees. System testing was performed over seven days with two irrigation sessions daily, during which sensor data transmission and notification timestamps were recorded. QoS parameters including throughput, packet loss, delay, and jitter were analyzed using Wireshark. The results show that sensor data and irrigation notifications were consistently delivered within 3–5 seconds, demonstrating stable real-time communication. QoS evaluation indicates 0% packet loss, an average delay of 180 ms, and an average jitter of 0.17 ms, with an overall QoS index of 3.02, classified as “Satisfied.” These findings confirm that MQTT provides reliable communication performance in plantation environments and effectively supports automated irrigation monitoring for improving agricultural efficiency.

Abstract

Automation of data extraction in financial documents is an urgent necessity for MYO Adventures to mitigate the risks of manual entry errors and operational inefficiencies. This study aims to evaluate the performance of Deep Computer Vision modules within an automated validation system through a comparative analysis between Connectionist Text Proposal Network (CTPN) and Efficient and Accurate Scene Text Detector (EAST) algorithms. The research methodology employs a quantitative experimental approach, testing both models against invoice and receipt datasets characterized by physical distortions and dense tabular layouts. Evaluation focuses on inference time metrics and text localization effectiveness prior to the Optical Character Recognition (OCR) stage. The results reveal a significant performance disparity, where the EAST algorithm recorded an average detection time of 565 ms, substantially more efficient than CTPN which required an extreme 12,046 ms. In terms of coverage accuracy, EAST demonstrated high robustness by successfully recognizing 74 valid text items, in contrast to CTPN which yielded only 14 readable items. The poor performance of CTPN is analyzed as a consequence of the limitations of its vertical anchor mechanism and Recurrent Neural Network (RNN) in handling the dense spacing variations of invoice tables, whereas the Fully Convolutional Network (FCN) architecture of EAST proved to be more adaptive. In conclusion, anchor-free methods like EAST possess superior reliability and computational efficiency, making them the most viable solution for implementing real-time financial validation systems on MYO Adventures' web-based platform.

Abstract

Attendance recording is a crucial administrative activity in educational institutions because it is directly linked to discipline, reporting, and decision-making at the school level. However, manual attendance procedures are still widely used and often generate various problems, including delays in recapitulation, inconsistent data formats, potential duplicate records, and limited access to information required for periodic monitoring. In response to these issues, this study aims to design and evaluate a web-based online attendance application that supports a more systematic, measurable, and accountable attendance management process through login-based user authentication. The methodology includes a needs analysis involving key stakeholders administrators, homeroom teachers, subject teachers, and students which is then translated into a role-based system design. Subsequent stages comprise prototype development, functional testing to ensure feature compliance with specifications, and usability evaluation to assess ease of use and user acceptance. The developed application provides core functionalities such as role-based user management, daily attendance entry, input validation to minimize errors and prevent duplication, and change-history logging (audit trails) to strengthen data integrity and traceability. In addition, the system offers automated recapitulation and attendance trend visualization across daily, weekly, and monthly periods to make monitoring faster and more informative. The system is implemented as a web application using the Laravel framework and a responsive interface to ensure accessibility across multiple devices. Functional testing results indicate that the main features operate as intended, while usability evaluation suggests that the application is easy to use and improves work efficiency compared to manual procedures. Overall, the findings confirm that a web-based attendance system reinforced by data integrity mechanisms and periodic reporting can enhance monitoring effectiveness, accelerate recapitulation processes, and strengthen the accountability of attendance records in schools.

Abstract

Neonatal sepsis is a condition caused by bacterial infection in infants during the neonatal period and is one of the leading causes of newborn mortality in many countries around the world, including Indonesia. Indonesia ranks fifth among Southeast Asian countries with the highest neonatal mortality rate. Most of these deaths can essentially be prevented through effective prevention, early diagnosis, and prompt treatment and care. This study aims to develop a web-based expert system application designed to perform early detection of neonatal sepsis, capable of storing and managing knowledge similar to that of a medical expert. The Certainty Factor method is used to calculate and measure the level of confidence in the diagnostic results, while the Forward Chaining method serves as the reasoning mechanism to generate conclusions based on the symptoms selected by the user. The expert system provides comprehensive information on symptoms, treatment steps, care procedures, and medical advice, thereby assisting both healthcare professionals and the public in identifying sepsis risks at an early stage. The testing results show that the expert system can provide a diagnostic confidence level of 94.77%, indicating the system’s accuracy in supporting clinical decision-making and its potential to help reduce neonatal mortality rates.
