%X Pineapple waste was produced by industry of Indonesia. Pineapple waste contains  cellulose. Cellulose can be modified by cysteine-citric acid become anti corrosion  coating material as aerogel. Cellulose was modified in 10%-10% of cysteine-citric  acid mixture solution. Modified cellulose aerogel was synthesized by using  Tetraethyl Orthosilicate (TEOS) by ratio 1 gram:5 mL. The functional groups of  the synthesize process were observed by Fourier Transform Infrared (FTIR). HCl  5%; 10%; and 15: solution was used as corrosive medium of the stainless steel  304.Coating process applied sol-gel dip coating for 30 seconds. Corrosive medium  damage to stainless steel was observed by using Scanning Electron Microscope  (SEM). Gravimetric was used to find out the weight change to calculate Inhibitor  Efficiency (IE). The results of IE of variation HCl 5%: 10%; and 15 are 23.37%,  21.80%, and 12.81%, respectively.  Keywords: Cellulose; Sol-gel dip coating; FTIR; SEM; Inhibitor Efficiency    Limbah nanas diproduksi oleh industry di Indonesia. Limbah nanas mengandung  selulosa. Selulosa dapat dimodifikasi dengan sistein-asam sitrat menjadi material  anti korosi sebagai aerogel. Selulosa dimodifikasi dengan campuran sistein-asam  sitrat sebesar 10%-10%. Selulosa aerogel termodifikas disintesis menggunakan  Tetraetil Ortosilikat (TEOS) dengan perbandingan 1 gram:5 mL. Gugus fungsi dari  proses sintesis diamati menggunakan Fourier Transform Infrared (FTIR). HCl 5%;  10%; dan 15% digunakan sebagai media korosif terhadap baja anti karat 304 Proses  pelapisan menggunakan metode pencelupan sol-gel selama 30 detik. Media korosi.  Mofrologi baja anti karat diamati menggunakan Scanning Electron Microscope  (SEM). Metode gravimetri digunakan untuk mengetahui perubahan berat untuk  mengetahui Efisiensi Inhibisi. Hasil dari Efisiensi Inhibisi pada varias HCl 5%;  10%; dan 15% adalah masing-masing 23.37%; 21,80%; dan 12,81%  Kata kunci: selulosa, pencelupan sol-gel, FTIR, SEM, Efisiensi Inhibisi
