Abstract

AC split adalah perangkat pendingin aktif yang dirancang untuk menjaga kenyamanan termal di dalam ruangan. Setpoint suhu ruangan merupakan faktor utama yang mempengaruhi konsumsi energi pada AC split. Penyesuaian suhu secara manual melalui remote control yang tidak sesuai dengan beban panas ruangan dapat menyebabkan penggunaan energi yang boros. Oleh karena itu, sistem pemantauan dan pengendalian yang fleksibel dengan akses jarak jauh dan real-time menjadi sangat penting. Penelitian ini mengembangkan sistem pemantauan suhu dan konsumsi energi untuk AC split berbasis teknologi IoT dengan mengintegrasikan mikrokontroler NodeMCU ESP8266, sensor DHT22, sensor PZEM-016, dan pemancar LED inframerah dalam platform Blynk IoT. Sistem ini diuji pada AC split berkapasitas 1 PK di ruangan berukuran 4 m x 4 m dengan setpoint suhu 22 ºC selama 7 jam. Hasil pengujian menunjukkan fluktuasi suhu ruangan antara 21.5 ºC hingga 25.2 ºC dalam 100 menit selama siklus hidup/mati AC, dengan konsumsi energi total sebesar 5.3 kWh dan daya rata-rata 757 W. Temuan ini menegaskan potensi besar teknologi IoT dalam mendukung pengelolaan energi yang lebih cerdas dan pengoperasian AC split yang lebih terintegrasi.

Abstract

Ultrasonic atomizers can potentially augment the production of sea salt through a process known as ultrasonic nebulization. While the traditional method of sea salt production primarily relies on natural evaporation, ultrasonic atomization can accelerate the evaporation process. The process typically involves the following steps: collection of seawater, evaporation, brine crystallization and then harvesting process of the sea salt. After processing, the sea salt is typically dried and packaged for distribution and sale. In this project, influencing of ultrasonic atomizer in the process a saline water into the brine, before crystallization can be proceeded. The ultrasonic atomization process significantly increases the surface area of the seawater by converting it into fine droplets. Droplets evaporate more efficient due to large surface area of the droplets. According to testing of the research apparatus which had been conducted, an ultrasonic atomization can increase the salinity by brine evaporation or of droplet productivity of sea salt. This result had been shown that this process can be used to increasing the salinity of sea water. For further steps, this technique can potentially augment the production of sea salt.
