      Abstract
      Minyak ikan sebagai hasil samping industri penepungan ikan merupakan bahan yang berpotensi untuk dimanfaatkan kembali apabila mengalami proses pengolahan lebih lanjut. Hal yang dapat dilakukan adalah proses pemucatan. Studi ini bertujuan mengetahui kualitas minyak ikan sebelum dan setelah penambahan adsorben, mendapatkan informasi kondisi proses pemucatan terbaik, mengetahui pengaruh jenis dan konsentrasi terbaik dari adsorben terhadap kualitas minyak ikan, mendapatkan adsorben dan konsentrasi terbaik. Minyak ikan kasar dilakukan penimbangan dan dipanaskan. Kemudian, pada saat suhu telah mencapai 55-60 oC ditambahkan adsorben dengan berbagai konsentrasi. Minyak kemudian dipanaskan kembali dan diaduk pada suhu 80 oC selama 30 menit. Setelah itu, minyak disentrifugasi pada 6500 rpm selama 20 menit. Jenis dan adsorben terbaik untuk proses pemucatan diperoleh menggunakan adsorben zeolit dengan konsentrasi 5%. Interaksi jenis dan konsentrasi adsorben berpengaruh secara signifikan pada setiap parameter uji rendemen, densitas, viskositas, kadar asam lemak bebas, bilangan asam, bilangan peroksida, bilangan total oksidasi dan bilangan p-anisidin terhadap kualitas minyak ikan.
       
      As a by-product of the fish meal processing byproduct industry, fish oil is a material that has the potential to be reused if it undergoes further processing. What can be done is the bleaching process. This study aims to determine the quality of fish oil before and after the addition of adsorbent, obtain information on the best bleaching process conditions, determine the effect of the best type and concentration of adsorbent on the quality of fish oil, obtain the best adsorbent and concentration. Crude fish oil is weighed and heated. Then, when the temperature has reached 55- 60 oC, adsorbents with various concentrations are added. The oil was then reheated and stirred at 80 oC for 30 minutes. After that, the oil was centrifuged at 6500 rpm for 20 minutes. The best type and adsorbent for the bleaching process was obtained using zeolite adsorbent with a concentration of 5%. The interaction of adsorbent type and concentration significantly affected each test parameter of yield, density, viscosity, free fatty acid content, acid number, peroxide number, total oxidation number, and p-anisidine number on the quality of fish oil.
