Abstract

Abstract: This study aims to determine the physical and chemical quality of fish oil from the flesh of Pangasius microcinema. The quality of extracted fish oil can be improved through a refining process. Before and after the purification process, the quality of crude fish oil was analyzed, including acid value (AV), saponification value (SV), iodine value (IV), peroxide value (PV), and p-anisidine value (An-V). The results of the characterization of patin fish oil (PFO) in meat were carried out with 3 purifications, namely purification without activated carbon purification treatment with bentonite, the value of susceptibility to acid value, peroxide value, saponification value, iodine value, and p-anisidinee value, which ranged from 1.92-2.64 mg KOH/g, peroxide value 3.76-4.87 meq O2/kg, iodine value 80.46-81.39 g I2/100g, saponification value 189.48-196.75 mg KOH/g, and p-anisidinee value 5.95-8.93 meq/kg. The best refining process is the oil extracted from patin fish oil meat oil and distilled using bentonite from dry rendering because the processed fish oil is good in the standards set by the International Association of Fish Flour Producers, Indonesian Fish Oil Standards, and as food fish oil grades.

Abstract

Sidaguri atau Sida rhombifolia L. telah digunakan oleh masyarakat sebagai obat tradisional, yaitu: penghilang rasa nyeri, radang, asam urat, penyakit kuning, muntah darah, dan sakit gigi. Faktor yang mempengaruhi produksi kandungan metabolit sekunder adalah kondisi lingkungan seperti tempat tumbuh, iklim, interaksi intra dan inter-spesifik serta waktu panen. Penelitian ini bertujuan untuk mengetahui aktivitas antioksidan serta kadar flavonoid dan fenolik total ekstrak sidaguri berdasarkan tempat tumbuh. Sampel diekstraksi dengan ultrasonic-assisted extraction (UAE) dan diuji penangkapan radikal bebas menggunakan metode 2,2’-difenil-1-pikrilhidrazil (DPPH) dan 2,2’-azino-bis(3-diethyl4benzothiazoline-6-sulfonic acid) (ABTS), serta penetapan kadar flavonoid total dan kandungan fenolik total. Hasil uji aktivitas antioksidan sidaguri dari Cangkringan dan Ngemplak memiliki aktivitas antioksidan tertinggi baik pada metode penangkapan radikal DPPH dengan nilai IC50 masing-masing sebesar 0,400±0,004 dan 0,403±0,004 mg/mL, maupun metode ABTS dengan nilai TEAC masing-masing sebesar 40,733±0,240 dan 35,598±0,153 mg/g serbuk sidaguri, dengan kadar flavonoid total masing-masing sebesar 10,095±0,068 dan 12,066±0,025 mg/g serbuk sidaguri dan kadar fenolik total masing-masing sebesar 56,45±0,068 dan 31,502±0,025 mg/g serbuk sidaguri.
