      Abstract
      Minyak goreng berfungsi sebagai media penghantar panas, namun penggunaan berulang menurunkan kualitas dan berpotensi membahayakan kesehatan. Regenerasi minyak jelantah dapat dilakukan melalui adsorpsi yang efektif dan ekonomis menggunakan adsorben alami. Biji alpukat berpotensi sebagai adsorben karena mengandung lignoselulosa (selulosa, hemiselulosa, lignin) dengan gugus aktif dan struktur berpori yang mampu mengikat senyawa pengotor. Penelitian ini bertujuan menganalisis pengaruh serbuk biji alpukat terhadap kualitas minyak jelantah berdasarkan parameter asam lemak bebas, bilangan peroksida, dan nilai total oksidasi. Metode yang digunakan adalah adsorpsi dengan variasi konsentrasi aktivasi HCl dan massa adsorben. Hasil menunjukkan kondisi optimum pada HCl 2 M dan massa 4 g dengan asam lemak bebas 0,6186% dan bilangan peroksida 1,8133 meq O2/kg, sedangkan penurunan total oksidasi tertinggi diperoleh pada HCl 3 M dan massa 4 g dengan nilai Totox 12,39. Hasil ini menunjukkan adsorben biji alpukat efektif meningkatkan kualitas minyak jelantah.
       
      Cooking oil serves as a heat transfer medium, but repeated use degrades its quality and poses potential health risks. Used cooking oil could be regenerated through effective and economical adsorption using natural adsorbents. Avocado seeds had potential as adsorbents because they contained lignocellulose (cellulose, hemicellulose, lignin) with active groups and a porous structure capable of binding impurity compounds. This study aims to analyze the effect of avocado seed powder on the quality of used cooking oil based on the parameters of free fatty acids, peroxide value, and total oxidation value. The method used was adsorption with variations in HCl activation concentration and adsorbent mass. The results showed optimal conditions at 2 M HCl and a mass of 4 g, with free fatty acids at 0.6186 % FFA and a peroxide value of 1.8133 meq O2/kg, while the highest reduction in total oxidation was obtained at 3 M HCl and a mass of 4 g, with a Totox value of 12.39. These results indicate that avocado seed adsorbent effectively improves the quality of used cooking oil.
