Abstract

Beton bertulang sebagai bahan utama berdirinya sebuah infrastruktur bangunan terdiri dari semen dan besi maupun baja yang sangat berpotensi terkorosi oleh lapisan aktif dan pasif penyusun beton yang menyebabkan retakan hingga pecahnya beton dan bangunan menjadi roboh yang dipengaruhi oleh permeabilitas dan ketahanan beton. Maka sistem monitoring laju korosi beton menggunakan uji resistivitas berbasis internet of things ini perlu dibuat. Sistem monitoring ini dibuat berupa prototipe menggunakan sensor INA 219 dan mikrokontroler NodeMCU ESP8266, ketahanan dan laju korosi yang ditampilkan pada LCD dan dapat dimonitoring melalui aplikasi Blynk. Sehingga pengujian selama 5 hari menghasilkan laju korosi pada beton bertulang dengan beton uji silinder menggunakan prototipe pada beton uji silinder pengondisian perendaman air campuran garam yaitu 0,0001112 µm/year dan pada beton uji silinder pengondisian air normal yaitu 0,00022 µm/year dengan masing-masing besar resistivitas beton yaitu 81,8kꭥ dan 40,8kꭥ dengan laju korosi bersifat pasif.

Reinforced concrete as the main material for the establishment of a building infrastructure consists of cement and iron and steel which have the potential to be corroded by the active and passive layers of the concrete that cause cracks to break apart and the building to collapse which is influenced by the permeability and resistance of the concrete. So the concrete corrosion rate monitoring system using the internet of things-based resistivity test needs to be made. This monitoring system is made in the form of a prototype using the INA 219 sensor and NodeMCU ESP8266 microcontroller, the resistance and corrosion rate are displayed on the LCD and can be monitored through the Blynk application. So that the 5-day test resulted in the corrosion rate in reinforced concrete with cylinder test concrete using a prototype on the test concrete cylinder with saltwater immersion conditioning 0,0001112 m/year and in normal water conditioning cylinder test concrete 0,00022 m/year with each -respectively, the resistivity of concrete is 81.8kꭥ and 40.8kꭥ with a passive corrosion rate.
