Abstract
Korosi merupakan suatu hal yang tidak dapat dihindari tetapi korosi dapat di kendalikan, salah satu faktor yang menyebabkan meningkatnya laju korosi merupakan faktor lingkungan itu sendiri. Pada penelitian sebelumnya penggunaan inhibitor dengan menggunakan ekstrak kulit jeruk nipis sudah di lakukan dan memperoleh efisiensi tertinggi sebesar 99.888% dengan penambahan konsentrasi 200 mg pada baja API 5L grade B media larutan H2SO4 1M. Namun pada penelitian tersebut belum terdapat pengaruh faktor temperatur. Penelitian ini dilakukan dengan tujuan untuk mengembangkan penelitian sebelumnya, pengujian yang dilakukan yaitu Polarisasi, EIS, Weight Loss, dan SEM. Variasi yang digunakan pada penilitian ini adalah penambahan konsentrasi sebesar 200 mg, 500 mg, 1000 mg, 1200 mg, dan temperatur yang digunakan adalah 30°C , 40°C, 50°C. Pada pengujian polarisasi efisiensi tertinggi terletak pada temperatur 40°C konsentrasi 1000 mg sebesar 99.697 %, sedangkan pengujian EIS efisieni tertinggi dihasilkan pada temperatur 30°C konsentrasi 1200 mg sebesar 98.422%. Hasil SEM menunjukkan adanya lapisan tipis yang terbentuk sehingga dapat menghambat laju korosi.

Corrosion is something that cannot be avoided but corrosion can be controlled, one of the factors that causes an increase in corrosion rate is the environmental factor itself. In previous studies the use of inhibitors using lime peel extract has been done and obtained the highest efficiency of 99.888% with the addition of 200 mg concentrations in API 5L grade B steel media 1M H2SO4 solution. But in the study there was no effect of temperature factors. This research was conducted with the aim of developing previous research, the tests carried out were Polarization, EIS, Weight Loss, and SEM. The variations used in this study are the addition of a concentration of 200 mg, 500 mg, 1000 mg, 1200 mg, and the temperature used is 30 ° C, 40 ° C, 50 ° C. In the highest efficiency polarization test located at a temperature of 40 ° C the concentration of 1000 mg was 99,697%, while the highest EIS efficiency test was produced at a temperature of 30 ° C with a concentration of 1200 mg at 98.422%. SEM results indicate a thin layer formed so that it can inhibit the corrosion rate.
