Abstract
Goatfish is a demersal fish commonly found in the Java Sea, with a production of 442 tons at PPN Karangantu in 2022. Despite its high protein content (20-22%), its utilization remains limited as a side dish. The high protein content of goatfish has the potential to be processed into Fish Protein Concentrate (FPC), a stable product with a protein content of up to 70-80%. FPC is produced through extraction using organic solvents such as ethanol, which effectively yields high-quality protein. Determining the optimal extraction time is essential for producing goatfish protein concentrate. This study aims to determine the optimal extraction time for producing FPC using ethanol as a solvent. The research method was a laboratory experiment using a Completely Randomized Design (CRD) with four levels of treatment (0 hours, 2 hours, 3 hours, and 4 hours of extraction time). The research consisted of three stages: preparation, extraction, and drying. Results showed that 2 hours of extraction was the best treatment, with the following characteristics: whiteness degree of 20.3%, yield of 17.5%, protein content of 80.48%, fat content of 4.38%, ash content of 3.56%, moisture content of 7.66%, and carbohydrate content of 3.96%. In the functional properties test, the goatfish protein concentrate demonstrated a water absorption capacity of 2.74 mL/g, oil absorption capacity of 1.8 g/g, emulsion capacity of 1.27 mL/mL, bulk density of 0.63 g/mL, and gel formation of 2.5%. The protein concentrate of goatfish contains 17 types of amino acids, including 8 essential amino acids and 9 non-essential amino acids, and is classified as close to type B.

| Additional Information: | Ikan kuniran adalah ikan demersal yang banyak ditemukan di laut Jawa, dengan produksi mencapai 442 ton di PPN Karangantu pada tahun 2022. Meskipun kaya protein (20-22%), pemanfaatannya masih terbatas hanya sebagai lauk-pauk. Kandungan protein ikan kuniran yang tinggi berpotensi diolah menjadi Konsentrat Protein Ikan (KPI), dengan kandungan protein hingga 70-80%. KPI diproduksi melalui ekstraksi dengan pelarut organik, seperti etanol, yang efektif dalam menghasilkan protein berkualitas tinggi. Pada pembuatan konsentrat protein ikan kuniran perlu diketahui waktu ekstraksi yang optimal. Tujuan penelitian ini untuk menentukan waktu ekstraksi yang optimal pada proses pembuatan konsentrat potein ikan kuniran menggunakan pelarut etanol. Metode penelitian yang dilakukan yaitu eksperimental laboratorium menggunakan Rancangan Acak Lengkap (RAL) terdiri dari 4 taraf perlakuan dengan waktu ekstraksi yang berbeda (0, 2 , 3, dan 4 jam). Penelitian ini terdiri dari 3 tahapan yaitu preparasi, proses ekstraksi, dan pengeringan. Hasil penelitian ini menunjukkan bahwa waktu ekstraksi 2 jam adalah perlakuan terbaik dengan karakteristik derajat putih sebesar 20,3%, rendemen 17,5%, protein 80,48%, lemak 4,38% abu 3,56%, air 7,66%, dan karbohidrat 3,96%. Pada uji sifat fungsional, KPI kuniran memiliki nilai daya serap air 2,74 mL/g, daya serap minyak 1,8 g/g, kapasitas emulsi 1,27 mL/mL, densitas kamba 0,63 g/mL dan pembentukan gel 2,5%. Konsentrat protein ikan kuniran memiliki 17 jenis asam amino diantaranya 8 asam amino esensial serta 9 asam amino non-esensial dan mendekati tipe B. | |||||||||
