Abstract

Penelitian ini bertujuan untuk mengetahui lamanya waktu ekstraksi pigmen angkak dari ampas sagu menggunakan ultrasonic bath. Penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 3 kali ulangan yaitu A (ekstraksi 10 menit), B (ekstraksi 20 menit), C (ekstraksi 30 menit), D (ekstraksi 40 menit). Hasil penelitian menunjukkan bahwa bubuk pigmen hasil proses ekstraksi angkak ampas sagu selama 40 menit (perlakuan D) merupakan perlakuan terbaik, dimana intensitas pigmen tertinggi untuk λ 400 nm (kuning),  λ 470 nm (orange) dan λ 500 nm (merah ) yaitu 7,63 ; 6,91 dan 5,95. Karakteristik bubuk pigmen angkak (perlakuan D) memiliki nilai aktivias antioksidan 44,52% pada konsentrasi 1000 ppm, kandungan lovastatin 68,60 ppm, kadar air 4,83%, nilai pH 4,03 dan derajat kecerahan 26,76 oHue (merah keunguan).  AbstractThis study was aimed to determine the duration of angkak pigment extraction from sago waste  using ultrasonic bath. The study used a completely randomized design (CRD) with 4 treatments and 3 repetitions, A (extraction 10 minutes), B (extraction 20 minutes), C (extraction 30 minutes), D (extraction 40 minutes). The results showed that the powder pigment results of the extraction process angkak sago waste  for 40 minutes (treatment D) was the best treatment, where the highest intensity of the pigment for λ 400 nm (yellow), λ 470 nm (orange) and λ 500 nm (red) were 7.63; 6.91; and 5.95 respectively. Characteristic of angkak pigment powder (treatment D) had value of antioxidant activity 44.52% at concentration 1000 ppm, lovastatin content 68.60 ppm, water content 4.83%, pH value 4.03, and degree of brightness 26.76 oHue (red purple).
