Golden apple snail (Pomacea canaliculata) has been known as rice corps pest due to high adaptability and reproductive power. Utilization of Pomacea canaliculata’s eggs as raw materials in the food and health industry is one of the efforts to eradicate the pest snail. This study was aimed to identify the active compounds contained in the extract pigments of Pomacea canaliculata’s eggs. The methods of this study were extraction of pigments using acetone and methanol, analyzing the active compound (secondary metabolite) qualitatively, TLC to determine pigment components and LC-MS/MS to identify active compounds semi quantitatively. The results showed that active compounds in the methanol extract contain 11 carotenoid pigments of xanthophyl group, two carotenoid pigments of carotene group, and 2 active compounds in nonpigmented form, whereas the acetone extract contain 11 pigmentcarotenoids of xanthophyl group and 2 compounds active in non-pigment form.

Brown seaweeds contain various metabolites (carotenoids, laminarin, alginate, fucoidan, mannitol, and phlorotannin) as anticancer substances, antioxidants and chemopreventive agent against degenerative diseases. This research was aimed to determine the chemical properties and antioxidants activity of Sargassum polycystum, Padina minor and Turbinaria conoides. This research consisted of the proximate analysis, crude fiber, minerals, heavy metals, extraction, phytochemicals, analysis phenolic compound and antioxidant activity with DPPH, FRAP and CUPRAC methods. The results showed moisture content of S. polycystum, P. minor, and T. conoides 24-31%, fat 0.23-0,47%, protein 3-4%, ash 27-45%, carbohydrate 26-38% and crude fiber 2-6%. Mineral Fe S. polycystum, P.minor and T.conoides about 0.03 g/kg to 0.39 g/kg, Ca 11.28 g/kg to 27.98 g/kg, K 13.86 g/kg to 41.15 g/kg, Na 16.31 g/kg to 20.51 g/kg and Mg 8.04 g/ kg to 18.68 g/kg. The range of heavy metals Pb S. polycystum, P. m i n o r and T. conoides 3.48 mg/kg to 12.68 mg/kg, Hg 0.24 mg/kg to 0.53 mg/kg and Cu 5.66 mg/kg to 7.02 mg/kg. Ethanol extract of S. polycystum, P. minor, and T. conoides contains alkaloids, phenolic, flavonoids, saponins, steroids, and triterpenoids. Total phenolic compounds of brown seaweeds ranged from 3758.97-8287.18 mg GAE/g. Brown seaweeds contain DPPH antioxidant activities within IC50 values of 1.9-9.6 mg/mL, FRAP 70.643-105.357 µmol Trolox/g and CUPRAC 85.268-201 µmol Trolox/g.

Diversification of traditional food ilabulo made from raw catfish (Pangasius sp.) has the potential to be developed in Gorontalo province to substitute chicken viscera. The research aimed to make ilabulo substitute the raw material of chicken viscera with the catfish fortified Kappaphycus alvarezii seaweed and catfish bone meal and to determine the organoleptic and chemical characteristics of ilabulo catfish fortification. Fortified treatment is K. alvarezii and catfish bone (5 dan 10% ), B (10 and 15%) and C (15 dan 20%). The organoleptic analysis used a hedonic scale of favorite criteria on the appearance, texture, color, flavor, and taste. The results of organoleptic analysis continued with Bayes test. The chemical analysis used the Association of Official Analytical Chemist method. The result of the hedonic characteristic of ilabulo catfish fortification was on the appearance neutral criteria – like (5.53–7.03), texture neutral criteria – rather like (5.8–7.1), aroma rather like (6.3–6.73), color neutral – like (6.1–7.03) and taste (6.07–6.53) neutral criteria – rather like. The result of Bayes test obtained by a texture of importance value 5, appearance importance value 5, aroma of importance value 4, color of interest value 3 and taste of importance value 2. Characteristic of ilabulo culture of selected fortified catfish that was the fortification of K. alvarezii seaweed 15% and catfish bone flour (20%) (fortification C) obtained by water content 56.46%, ash 11.54%, protein 7.78%, fat 8.91%, coarse fiber 0.61%, carbohydrate 22.07% and calcium 0.315 %.
