    Abstract
    Kulit pisang awak mengandung tanin yang merupakan salah satu inhibitor yang dapat digunakan untuk melindungi logam dari korosi. Penelitian ini bertujuan mengetahui pengaruh kemampuan inhibisi tanin dalam bentuk serbuk, ekstrak pekat, dan tanin yang berasal dari kulit pisang awak pada plat besi dalam larutan asam klorida. Variabel-variabel yang diamati antara lain metode perendaman, konsentrasi inhibitor dan waktu perendaman. Parameter yang diteliti adalah laju korosi dan efisiensi besi. Pada penelitian ini, laju korosi terendah dan efisiensi inhibisi tertinggi diperoleh pada perendaman besi selama 12 hari di dalam larutan HCl dan penambahan 2,064 g/cm2 tanin inhibitor. Pada kondisi ini, laju korosi yang dicapai 7,25 mpy dan efisiensi inhibisi sebesar 97,79 %. Laju korosi dan efisiensi inhibisi terbaik yang dihasilkan dari inhibitor serbuk maupun ekstrak pekat diperoleh laju korosi sebesar 19,92 mpy dan efisiensi inhibisi sebesar 93,94 % pada penambahan inhibitor serbuk serta laju korosi sebesar 13,25 mpy dan efisiensi inhibisi sebesar 95,96 % pada penambahan inhibitor ekstrak pekat. Hasil yang diperoleh pada penelitian ini menunjukkan bahwa serbuk, ekstrak pekat dan tanin kulit pisang awak memiliki kinerja inhibisi korosi yang baik.
     
    Banana peel contains tannin could be used as corrosion protection of iron. This study aims to determine the effect of tannin inhibition ability in the form of powder, crude extract, and tannin from banana peel on corrosion inhibition of iron specimen in hydrochloric acid solution. The variables observed are soaking method, inhibitor concentration and immersion time. The parameters studied are corrosion rate of iron and corrosion inhibition efficiency. In this study, the lowest corrosion rate and highest inhibition efficiency are obtained on immersion of iron for 12 days in HCl solution and addition of 2,064 g/cm2 tannin inhibitor. In this condition, the corrosion rate is 7.25 mpy and the corrosion inhibition efficiency is 97.79 %. The best corrosion rate and corrosion inhibition efficiency resulting from powder and crude extract inhibitors obtained corrosion rate of 19.92 mpy and corrosion inhibition efficiency of 93.94 % on the addition of powder inhibitors and corrosion rate of 13.25 mpy and corroson inhibition efficiency of 95.96 % on the addition of crude extract inhibitors. The results showed that powder, crude extracts and tannin from Awak banana peel could be used as corrosion inhibition of iron in HCL solution.
