Abstract

Implementing the Over-The-Air (OTA) system, which facilitates wireless and remote updates of software or firmware through internet connectivity, offers a significant advantage by saving both time and effort. This approach allows for firmware updates to be performed directly from any location, eliminating the need to physically visit each device. This is especially advantageous in the manufacturing of air quality monitoring devices, where adjustments to programs and software are often needed, particularly with seasonal changes. Updating firmware manually on numerous devices can be a time-consuming and labor-intensive process. To address this issue, the proposed device will be designed to support air quality readings and will utilize an internet connection to enable virtual firmware updates. The device will periodically check its program storage for new firmware versions. When a new version is detected, the device will automatically download and install the latest firmware available. This process reduces the need for manual intervention and improves operational efficiency. Additionally, deploying multiple devices across a large area is crucial for ensuring comprehensive coverage. This approach not only simplifies maintenance but also enhances the operational management of air quality monitoring systems. By leveraging OTA technology, the process of updating devices becomes more streamlined, scalable, and efficient, contributing to more effective environmental monitoring and management.

Abstract

Penggunaan pupuk kimia dalam skala rumah tangga masih mendominasi, meskipun dampak jangka panjangnya dapat menurunkan kualitas tanah dan mencemari lingkungan. Sebaliknya, limbah organik rumah tangga seperti ampas kopi dan teh mengandung unsur hara yang dapat dimanfaatkan sebagai bahan pembuatan pupuk organik. Penelitian ini merancang dan merealisasikan alat pembuatan kompos berbasis ampas kopi dan teh dengan fungsi pencacahan, pengadukan, dan pengeringan otomatis menggunakan mikrokontroler Arduino Uno. Pengujian dilakukan pada komponen utama seperti sensor beban, sensor kelembapan, dan heater untuk memastikan sistem bekerja sesuai rancangan. Hasil pengujian menunjukkan bahwa sensor beban mampu mengukur massa dengan akurasi tinggi, sedangkan sensor kelembapan dapat mendeteksi penurunan kadar air bahan selama proses pengeringan. Selanjutnya, pupuk yang dihasilkan diuji pada tanaman mawar dan kangkung dengan beberapa variasi komposisi. Pengujian menunjukkan adanya perbedaan respon pertumbuhan tanaman berdasarkan variasi komposisi pupuk yang diberikan. Penelitian ini menegaskan bahwa limbah organik rumah tangga dapat diolah secara otomatis menjadi pupuk organik yang bermanfaat serta ramah lingkungan.
