Abstract
Penelitian ini bertujuan untuk mengetahui pengaruh konsentrasi ekstrak daun kemangi dan konsentrasi karagenan terhadap karakteristik fisik, kimia, dan organoleptik permen jeli yang dihasilkan. Penelitian ini dilaksanakan di Laboratorium Kimia Hasil Pertanian dan Laboratorium Sensoris Jurusan Teknologi Pertanian, Fakultas Pertanian, Universitas Sriwijaya, Indralaya, dimulai dari bulan April hingga Oktober 2014. Penelitian ini menggunakan Rancangan Acak Lengkap Faktorial (RALF) yang terdiri atas 2 faktor perlakuan. Faktor perlakuannya yaitu konsentrasi ekstrak daun kemangi (30%, 45 % dan 60%) dan konsentrasi karagenan (2 %, 4% dan 6 %), masing-masing perlakuan diulang sebanyak 3 kali. Parameter yang diamati meliputi analisa fisik (tekstur dan warna), analisa kimia (kadar air, kadar abu, total padatan terlarut, dan total fenol), dan analisa sensoris (aroma, warna, tekstur, dan rasa). Hasil penelitian menunjukkan bahwa perlakuan konsentrasi ekstrak daun kemangi berpengaruh nyata terhadap nilai kadar air, kadar abu, total fenol, tekstur dan warna (lightness, redness, dan yellowness). Perlakuan konsentrasi karagenan berpengaruh nyata terhadap nilai kadar air, kadar abu, total padatan terlarut, tekstur, dan warna (ilightness, redness, dan yellowness). Interaksi konsentrasi ekstrak daun kemangi dan konsentrasi karagenan berpengaruh nyata terhadap kadar air, kadar abu, tekstur dan warna {redness). Perlakuan terbaik permen jeli daun kemangi dengan karagenan berdasarkan metode De Garmo adalah dengan konsentrasi ekstrak 60% dan konsentrasi karagenan 2%. Permen jeli terbaik yang dihasilkan memiliki karakteristik: tekstur 559,6 gf, lightness 34,6%, redness 3,1, yellowness 11,2, kadar air 43,5 %, kadar abu 0,9%, total padatan terlarut 29,5 °Brix, total fenol 146,31 mg/L, aroma 2,68, tekstur 2,56, warna 2,32, dan rasa 2,32.
