Abstract

Fire is a serious disaster that causes significant losses in terms of both material assets and loss of life, especially in densely populated residential areas. Fires that occur in one house can easily spread to other houses. To prevent this issue, an early fire detection and automatic fire suppression system has been developed for homes based on the Internet of Things (IoT) using NodeMCU ESP32. This system has the ability to detect early signs of fire, gas, and temperature conditions, and takes automatic action when potential fire hazards are detected. Additionally, the system sends real-time push notifications to users' Android applications to provide warning messages. Test results indicate that the fire sensor can detect flames up to a distance of 130 cm with an average notification delay of approximately 2,37 seconds. The MQ-2 gas sensor can detect butane gas up to a distance of 170 cm with an average notification delay of about 2,84 seconds, while the DHT22 temperature sensor has an average accuracy of approximately 98,52% with a notification delay of about 2,03 seconds.

Abstract

Determining the nutritional status of toddlers is essential for monitoring growth and preventing long-term health problems. Manual assessment requires significant time and is prone to human error; therefore, an automatic detection system based on height and weight parameters is needed. This study aims to develop a Real-Time Operating System (RTOS)–based system to detect the nutritional status of children aged 24–60 months, capable of managing task priorities, ensuring timely execution, and preventing race conditions using semaphores. The system employs an ultrasonic sensor to measure height, load cell sensors to measure body weight, and a web-based interface to input gender and age. Nutritional classification is determined through Z-score calculations using WHO reference data. Tests conducted on 200 children in various locations showed that the ultrasonic sensor achieved an average absolute error of 0.39 cm, a relative error of 0.409%, and an accuracy of 99.59%, while the load cell sensor achieved an average absolute error of 0.22 kg, a relative error of 1.587%, and an accuracy of 98.41%. The average execution times for the measurement and Z-score computation tasks were 4014.4 ms and 11.31 ms, respectively. The nutritional status classification results showed accuracy levels of 99.5% for Weight-for-Age (W/A), 99.5% for Height-for-Age (H/A), and 97.5% for Body Mass Index-for-Age (BMI/A) compared with manual assessments.

Abstract

Buah Jeruk Pontianak merupakan salah satu komoditas unggulan hortikultura di Kota Pontianak karena dikenal memiliki cita rasa khas, yaitu manis dengan sedikit asam. Meskipun memiliki popularitas tinggi di pasar lokal maupun ekspor, proses pemilahan kualitas tingkat kematangan buah jeruk Pontianak masih banyak dilakukan secara manual dengan mengandalkan pengamatan visual terhadap warna, pori-pori, dan kondisi kulit. Metode manual ini memerlukan waktu yang lama, bersifat subjektif, serta memiliki tingkat akurasi yang rendah. Padahal, keseragaman warna kulit buah merupakan salah satu standar penting dalam memenuhi permintaan pasar ekspor dan swalayan. Dalam penelitian ini dikembangkan sistem pemilahan kualitas jeruk Pontianak berdasarkan warna kulitnya. Sistem ini menggunakan sensor warna TCS3200 untuk mendeteksi warna pada jeruk Pontianak, dengan Arduino Mega 2560 sebagai pengendali utama. Perangkat keras yang digunakan terdiri atas LED COB, tiga buah motor servo, konveyor, dan LCD. Hasil pengujian menggunakan 90 buah jeruk untuk setiap kategori tingkat kematangan, yaitu hijau (mentah), hijau kekuningan (setengah matang), dan kuning (matang), menunjukkan bahwa tingkat akurasi pemilahan menggunakan sensor warna TCS3200 mencapai 83,33%.

Abstract

Energi listrik berperan vital dalam kehidupan, namun konsumsi yang tidak efisien, khususnya pada pencahayaan, dapat membebani biaya dan sumber daya. Pada ekosistem buatan seperti aquascape, pencahayaan tidak hanya berfungsi sebagai estetika tetapi juga krusial bagi kesehatan biota di dalamnya, di mana intensitas yang tidak tepat dapat memicu stres pada fauna dan pertumbuhan alga yang tidak diinginkan. Penelitian ini bertujuan mengembangkan sistem kontrol lampu otomatis hemat energi untuk aquascape menggunakan mikrokontroler NodeMCU ESP32 dan sensor LDR. Sistem ini mengintegrasikan logika Rule Based System untuk adaptasi terhadap kondisi cahaya lingkungan dengan kontroler Proportional Integral Derivative (PID) untuk optimasi stabilitas dan kecepatan respons. Parameter PID ditentukan menggunakan dua metode, yaitu Ziegler Nichols Open Loop dan Closed Loop, untuk kemudian dibandingkan performa dari kedua metode tersebut. Hasil perbandingan menunjukkan bahwa metode Ziegler Nichols Closed Loop memperoleh nilai sehingga memberikan kinerja yang jauh lebih optimal dibandingkan metode Open Loop yang nilainya relatif kecil dengan nilai . Sistem yang dihasilkan dari metode Closed Loop terbukti lebih cepat mencapai target dan mampu mengoreksi error secara cepat, sehingga berhasil menciptakan sistem pencahayaan yang adaptif dan stabil.
