Abstract

Keamanan adalah salah satu perhatian utama mereka yang ingin mengadopsi dan bermigrasi ke teknologi Cloud Computing. Masalah keamanan yang digunakan oleh teknologi cloud mengungkapkan bahwa mobile cloud computing meningkatkan masalah privasi dan keamanan seperti masalah identifikasi dan otentikasi, karena terkadang identitas dan otentikasi pemilik perangkat atau pemilik data yang terdapat di cloud dapat terdeteksi. Ini adalah beberapa contoh yang dapat dianggap sebagai kemunduran besar pada adaptasi Mobile Cloud Computing dan alasan mengapa beberapa perusahaan masih enggan merangkul, mengadopsi, dan bermigrasi ke teknologi ini. Penelitian ini mengulas fenomena mobile cloud computing, dan masalah keamanan dan privasi dalam area aplikasi mobile dan Cloud Computing dengan lebih menekankan pada pertimbangan keamanan dan privasi untuk merangkul dan bermigrasi ke mobile cloud computing. Kata    kunci:  Cloud Computing, Keamanan Informasi, Privasi, Mobile Cloud Computing

Abstract

Dengue Hemorrhagic Fever (DHF) is a localized disease that continues to contribute to a high number of cases in Medan City. The local health authority faces challenges in identifying priority areas for effective prevention and control. This study applies data clustering techniques to map DHF risk areas by comparing the performance of K-Means and K-Medoids algorithms. The optimal number of clusters was determined using the Silhouette Coefficient, while the clustering quality was assessed using the Davies-Bouldin Index (DBI). The findings indicate that K-Means performs best with four clusters and achieves a lower DBI value compared to K-Medoids. Based on this, the study recommends using K-Means to categorize DHF risk areas into four priority levels: high, medium, low, and very low. This approach is expected to support the Medan City Health Office in implementing more targeted and efficient DHF control strategies.

Abstract

Hydroponic cultivation offers an innovative solution to land limitations and supports sustainable agricultural practices. This study presents the design and implementation of an Internet of Things (IoT)-based monitoring and control system for melon cultivation using the Deep Flow Technique (DFT), enhanced with a rule-based decision-making method. The system integrates an ESP32 microcontroller with multiple sensors—including pH, temperature, TDS, and ultrasonic sensors—to monitor key parameters of the nutrient solution in real time. A rule-based algorithm is applied to automatically regulate system responses to environmental changes, such as imbalances in pH levels, nutrient concentration, and water height. The collected data is displayed through a web-based platform and Telegram notifications, enabling remote access and management. System functionality was tested under various simulated conditions to evaluate accuracy and responsiveness. The results demonstrate that the system effectively maintains the hydroponic environment within optimal ranges, promoting healthy melon growth. This implementation enhances efficiency in monitoring and control, and contributes to the advancement of smart farming technologies powered by IoT.

Abstract

Indonesia, as an agricultural country, still faces serious challenges in the farming sector, particularly pest attacks from birds and insects that significantly reduce rice productivity and may lead to crop failure. The use of traditional methods and chemical pesticides is considered ineffective and has negative impacts on health and the environment. This study aims to design a prototype of an automated pest repellent system for agriculture based on the Internet of Things (IoT) that is environmentally friendly, energy-efficient, and easy to operate by local farmers. The research method employed a prototyping approach, which includes problem identification, hardware and software design, testing, and system evaluation. The device consists of a NodeMCU ESP32 microcontroller, a PIR sensor to detect pest movement, relay, ultrasonic speaker, electric net, and solar panel as the main power source. Testing on a miniature rice field model showed that the system could detect pest movement at a distance of approximately 5 meters and automatically activate the ultrasonic speaker with a range of 50–100 meters to repel birds, and the electric net to catch insects at night. Energy consumption is primarily supplied by the solar panel, and a fully charged battery can power the system for about 3 hours without sunlight. The detection success rate reached more than 85% with consistent actuator response. This system has proven to reduce pesticide dependency, is environmentally friendly, and has the potential to increase rice farming efficiency.

Abstract

Pendidikan berperan penting dalam pembangunan bangsa dan peningkatan kualitas hidup masyarakat. Sekolah sebagai institusi pendidikan formal membutuhkan lingkungan belajar yang sehat dan nyaman untuk mendukung proses belajar-mengajar. Salah satu faktor utama yang memengaruhi kenyamanan belajar adalah kualitas udara. Penelitian ini bertujuan untuk memantau kualitas udara di ruang kelas SD Sukma Bangsa Bireuen, Provinsi Aceh, menggunakan konsep Internet of Things (IoT) dengan membandingkan dua protokol komunikasi, yaitu MQTT dan HTTP. Parameter udara yang dipantau meliputi suhu, kelembapan, CO, CO₂, PM1, dan PM2.5. Hasil pengujian pada 10 sampel data menunjukkan bahwa protokol MQTT memiliki rata-rata waktu pengiriman data sebesar 6,2 milidetik, sedangkan protokol HTTP memerlukan rata-rata waktu 267 milidetik, menunjukkan bahwa MQTT sekitar 97,7% lebih cepat. Pada sesi pertama (pagi–siang), terjadi kenaikan suhu hingga 1,7°C, penurunan kelembapan sekitar 5%, sementara kadar CO dan CO₂, serta konsentrasi PM1 dan PM2.5 masih dalam batas aman. Sesi kedua (malam) menunjukkan penurunan suhu sekitar 2°C, kenaikan kelembapan sebesar 8%, dan peningkatan kadar CO₂ hingga 22,5% karena minimnya sirkulasi udara. Dashboard yang dibangun menggunakan Node-RED dapat menampilkan data secara real-time dari kedua protokol dengan lancar. Selain itu, sistem juga diintegrasikan dengan fitur notifikasi melalui Telegram, yang mampu mengirimkan peringatan otomatis setiap 10 menit jika parameter melebihi ambang batas, serta melayani permintaan data secara langsung dari pengguna. Dengan efisiensi pengiriman data, fleksibilitas arsitektur, dan kemampuan notifikasi real-time, sistem ini tidak hanya efektif untuk lingkungan kelas, tetapi juga berpotensi direplikasi pada ruang tertutup lainnya seperti laboratorium, ruang guru, dan ruang publik lainnya di lingkungan pendidikan.   Abstract Education plays an essential role in national development and improving the quality of life in society. Schools, as formal educational institutions, require a healthy and comfortable learning environment to support the teaching and learning process. One of the main factors affecting learning comfort is air quality. This study aims to monitor air quality in a classroom at SD Sukma Bangsa Bireuen, Aceh Province, using the Internet of Things (IoT) concept by comparing two communication protocols: MQTT and HTTP. The monitored air parameters include temperature, humidity, CO, CO₂, PM1, and PM2.5. Test results from 10 data samples show that the MQTT protocol achieved an average data transmission time of 6.2 milliseconds, while the HTTP protocol required an average of 267 milliseconds, indicating that MQTT is approximately 97.7% faster. During the first session (morning to afternoon), there was an increase in temperature of up to 1.7°C and a decrease in humidity of about 5%, while CO and CO₂ levels and PM1 and PM2.5 concentrations remained within safe limits. The second session (evening) showed a temperature drop of about 2°C, an increase in humidity by 8%, and a rise in CO₂ levels by up to 22.5% due to limited air circulation. The dashboard built using Node-RED successfully displayed real-time data from both protocols. Additionally, the system was integrated with a Telegram notification feature that could automatically send alerts every 10 minutes if any parameter exceeded the threshold, as well as respond to real-time data requests from users. With efficient data transmission, flexible architecture, and real-time notification capabilities, the system is not only effective for classroom environments but also has the potential to be replicated in other enclosed spaces such as laboratories, teacher rooms, and public areas within educational institutions.
