      Abstract
      Koperasi W merupakan suatu unit usaha yang berbasis pengolahan kelapa menjadi produk turunannya. Permasalahan Koperasi W yaitu aroma dan warna minyak goreng kelapa yang kurang dapat diterima oleh konsumen. Minyak goreng kelapa tersebut diproduksi dengan metoda basah dari perasan santannya dan dimurnikan dengan tahapan pemanasan, netralisasi, pemucatan, penghilangan bau, dan penyaringan. Tujuan penelitian untuk meningkatkan mutu produk minyak goreng kelapa yang meliputi kadar air, asam lemak bebas, bilangan peroksida, aroma, dan warna minyak goreng kelapa yang kurang dapat diterima oleh konsumen produk minyak goreng kelapa Koperasi W. Metode yang digunakan untuk meningkat mutu minyak goreng kelapa yaitu dengan metode pemucatan menggunakan kombinasi arang aktif dan bentonit. Hasil perbaikan 1 yaitu kombinasi adsorben yang optimal adalah 5% bentonit: 5% arang aktif: 200g minyak. Rendemen skala pabrik yang diperoleh 82% dan hasil uji organoleptik untuk warna dan aroma sudah berbeda nyata. Uji mutu minyak yaitu kadar air 0,15%, FFA 1,09%, bilangan peroksida 8,88mek O2/kg, protein 1,9%, dan transmitan warna 94,5%. Perbaikan 2 minyak goreng diperoleh hasil rendemen 94%, kadar air 0,095%, FFA 0,2%, bilangan peroksida 2,4mek O2/kg, protein 0,5%, dan transmitan warna 98%. Pemucatan menggunakan kombinasi arang aktif dan bentonit dapat meningkatkan mutu minyak goreng kelapa, antara lain kadar air, asam lemak bebas, bilangan peroksida, warna, dan aroma minyak goreng kelapa. Kata kunci: adsorben, aroma, minyak goreng kelapa, mutu, warna.
       
      Koperasi W is a business unit based on coconut processing into its derivative products. The problem with Koperasi W is that the aroma and color of coconut cooking oil are not acceptable to consumers. Coconut cooking oil is produced by the wet method from the coconut milk and purified by heating, neutralization, blanching, deodorizing, and filtering. Research purposes to improve the quality of coconut cooking oil products which include water content, free fatty acids, peroxide number, aroma, and colour of coconut cooking oil which are less acceptable to consumers of the product Koperasi W. The method used to improve the quality of coconut cooking oil is the bleaching method using a combination of activated charcoal and bentonite. The result of improvement 1 is that the optimal adsorbent combination is 5% bentonite: 5% activated charcoal: 200g oil. The yield of factory scale obtained was 82% and the results of organoleptic tests for color and aroma were significantly different. Oil quality tests were 0.15% water content, 1.09% FFA, peroxide number 8.88 mekO2/kg, protein 1.9%, and color transmittance 94.5%. The repair of 2 cooking oils obtained yields of 94%, water content 0.095%, FFA 0.2%, peroxide number 2,4mekO2/kg, protein 0.5%, and color transmittance 98%. Bleaching using a combination of activated charcoal and bentonite can improve the quality of coconut cooking oil, including water content, free fatty acids, peroxide value, color, and aroma of coconut cooking oil.
