Ekstrak Daun Kaliandra Sebagai Inhibitor Alami Laju Korosi St-37

Abstract: Ekstrak daun kaliandra merupakan salah satu inhibitor alami  yang  dapat digunakan untuk menghambat laju korosi karena didalamnya terdapat kandungan senyawa tanin. Penelitian ini  diawali dengan mengekstraksi daun kaliandra dengan cara maserasi kemudian dilanjutkan dengan evaporasi pada rotary vacuum evaporator untuk memisahkan pelarut dan ekstrak yang dihasilkan dan ekstrak tersebut digunakan sebagai inhibitor dengan konsentrasi 5%, 10%, dan 20 %. sampel uji korosi yang digunakan adalah baja ST-37 dengan ukur… Show more

“…Another study was conducted by Jufri et al, who used calliandra leaves as raw materials for making corrosion inhibitors because these leaves have a tannin content of approximately 10%, so they can be used as corrosion inhibitors in a metal [10]. This study aimed to determine the efficiency of calliandra leaf extract corrosion inhibitors in inhibiting the rate of metal corrosion in seawater corrosion medium.…”
