title = "Utilization of Tahongai stem bark (Kleinhovia hospita Linn.) extract as corrosion inhibitor on API 5L steel",
abstract = "Tahongai (Kleinhovia hospita Linn.) is one of herbal plant cultivated in Kalimantan. Tahongai stem bark extract (Kleinhovia hospita Linn.) is known containing antioxidant to prevent cancer cell growing, therefore it is expected to become a good organic corrosion inhibitor. Tests conducted in this study were: DPPH to prove the content of antioxidant compounds in Tahongai woods (Kleinhovia hospita Linn.) from which IC50 number is found to be 153.78 μg/mL, indicating intermediate power, Fourier Transform Infrared Specroscopy (FTIR) to determine the functional groups and compounds in Tahongai stem bark extract (Kleinhovia hospita Linn.) and suspected that flavonoid compound contained in extract, Open Circuit Potential (OCP) to obtain corrosion rate data and found that the slowest corrosion occurred on 400 ppm (30 days) with corrosion rate 8,74 × 10-4 mm/year. The most efficient inhibitor found in 400 ppm (30 days) with 92,063%.",
