Description Kulit ikan belut dan lele berpotensi untuk diekstrak gelatinnya. Kulit ikan belut dan lele tidak bersisik, berlendir dan berlemak untuk ikan lele, berbeda dengan kulit ikan pada umumnya yang dijadikan gelatin. Penelitian ini mempelajari tentang gelatin kulit ikan belut dan lele dari segi rendemen dan komposisi proksimat. Untuk mengetahui pengaruh pengeringan, kondisi kulit segar dan kering juga dipelajari. Tahapan ekstraksi yang dilakukan untuk keseluruhan jenis ikan sama, kecuali penanganan kulit ikan kering yang sebelumnya direndam dalam air selama 4 jam. Kulit ikan direndam kembali dalam 0,05M asam asetat selama 10 jam, kemudian dicuci dan diekstraksi dengan aquadest pada suhu 80OC selama 2 jam, cairan yang didapat difiltrasi. Filtratnya dikeringkan dalam cabinet dryer suhu 55OC selama        48 jam hingga diperoleh lembaran gelatin, kemudian diblender menjadi granula gelatin.Hasil penelitian menunjukkan bahwa gelatin kulit ikan kering mempunyai rendemen sedikit lebih rendah dibandingkan gelatin dari kulit ikan segarnya. Kadar protein gelatin kulit ikan kering telihat tinggi dibandingkan kulit segarnya. Pengeringan kulit ikan berpengaruh pada penurunan kadar abu dan lemak, namun tidak mempengaruhi kadar air gelatin hasil ekstraksi. Gelatin kulit segar ikan lele memiliki nilai rendemen tertinggi yaitu 22,01%. Komposisi proksimat yang terbaik diantara keseluruhan kondisi dan jenis kulit dapat dilihat pada gelatin kulit segar ikan belut dimana memiliki kadar air 9,91%; kadar abu 3,07%; kadar protein 91,61%; dan kadar lemak 0,82%.Skin of swam ell and catfish were potential to gelatin extracted. Swamp ell skin doesn’t have scales, with much mucus and a few fat for catfish, it’s different from another fish skin that gelatin extracted usually. This research was studied yield and proximate gelatin extracted from skin of swam ell and catfish. Influence of drying was observed too.The first stage of the research was raw material preparation (fresh and dry fish skin) soaked in aquadest for 4 hours. Fish skin extracted using 0,05 M acetic acid for      10 hours, washed in water and then extracted using aquadest at 80OC for 2 hours to get gelatin liquid, the liquid was filtrated. Filtrat was dried in cabinet dryer at 55OC for 48 hours to get gelatin layers, and then blended to get gelatin granule. The results were gelatin yield from dry fish skin lower than fresh fish skin. Gelatin protein from dry fish skin more higher than fresh skin. Influence of fish skin drying was decrease gelatin ash and fat, but gelatin moisture wasn’t influenced. Gelatin from fresh skin swamp ell was the best gelatin with moisture 9,91%, ash 3,07%, protein 91,61%, lipid 0,82%.
