Pengembangan Karakterisasi Gelembung Mikro Menggunakan Metode PIV beserta Pemantauan dengan IOT

Abstract

The development of microbubble technology has been widely used in various fields. One of these areas is sterilization technology using microbubbles to speed up and increase the effectiveness of the sterilization process. One example is room sterilization using vaporized ozone gas microbubbles which can minimize the spread of the Covid-19 virus. However, research and development of microbubbles are still not much related to the characterization of their size and hydrodynamic properties. In this study, we propose the development of a continuous characterization of the size of microbubbles using the image analysis method. Image analysis aims to find the displacement vector using particle image velocimetry (PIV) techniques. The Hadamard-Rybczynski equation was used to calculate the size of the microbubbles based on the rising velocity vector of the microbubbles. The image capture process uses an LED light shadow technique to get a brighter and more stable image. The template matching algorithm is used to speed up the displacement vector analysis process used in the PIV technique. The analysis process is carried out in-situ in parallel processing using the python program on the raspberry pi4 unit. The analysis process uses three program services that run parallel, namely recording, pre-processing, and processing services. The measurement process uses three validations, namely pixel validation, template matching algorithm validation, and interrogation window. Bubble size data is displayed in the form of real-time graphs and size distribution histograms online using IoT. The test results show the size distribution of the microbubbles produced has an average of 14.60 µm with a deviation value of 0.11µm.

Analisis Kinerja Pembangkit Gelembung Mikro dan Nano Tipe Pressurized Dissolution untuk Mengidentifikasi Potensi Penggunaannya di Bidang Pertanian

“…Penyumbatan suplai air akibat sirkulasi air terkontaminasi juga mungkin terjadi (Shen et al, 2022). Namun karakteristik gelembung yang dihasilkan memungkinkan untuk diaplikasikan di beberapa bidang (Han et al, 2022), termasuk di bidang pertanian secara luas (Hidayat, 2019 Hasil penelitian ini diharapkan dapat berguna untuk meningkatkan efisiensi dan efektifitasnya, demi mengevaluasi potensi aplikasinya di berbagai bidang (Han et al, 2022;Patel et al, 2021;Salim et al, 2021), yaitu dalam penelitian ini di bidang pertanian secara luas. Tujuannya yaitu mengembangkan teknologi MNB khususnya yang menggunakan metode pressurized dissolution sebagai bagian dari agroteknologi untuk mengatasi berbagai permasalahan di bidang pertanian.…”
