Abstract

Tuna (Thunnus sp.) is one of the leading fish commodities in Indonesia, especially in Gorontalo City, which is generally processed into loin, fillet, steak, canned products, and fresh products. Tuna can be used as a collagen producer. The purpose of this study was to extract and characterize collagen from tuna skin and bones. The results showed that the type of raw material affected the yield, water content, and FTIR of collagen. The yield in this study was 0.5% skin and 0.96% bone. Of the many wet materials processed, the dry collagen produced was small due to the acid concentration and also the materials used. The water content in skin collagen was higher than in bone, namely 13.32% skin and 6.96% bone. The physical characteristics of the collagen produced are FTIR analysis showing the presence of typical peaks of amide groups (A, I, II, III) which indicate the presence of collagen protein in skin collagen and in bone collagen the sample shows typical peaks of amide groups (A, I, II, III) which indicate the presence of collagen protein. Kata kunci:  FTIR, tuna, water content, collagen, tomini bay   Ikan tuna (Thunnus sp.) merupakan merupakan salah satu komoditas ikan unggulan di Indonesia, khususnya di Kota Gorontalo yang umumnya diolah dalam bentuk loin, filet, steak, produk dalam kaleng dan produk segar. Ikan tuna dapat dimanfaatkan sebagai penghasil kolagen. Tujuan penelitian ini adalah ekstrasi dan karakteristik kolagen dari kulit dan tulang ikan tuna. Hasil penelitian menunjukan bahwa jenis bahan baku berpengaruh terhadap rendemen, kadar air, dan FTIR kolagen. Rendemen pada penelitian ini yaitu kulit 0,5% dan tulang 0,96%. Dari banyak bahan basah yang diproses, kolagen kering yang dihasilkan sedikit disebabkan karena konsentrasi asam dan juga bahan yang digunakan. Kadar air pada kolagen kulit lebih tinggi dibandingkan tulang yaitu kulit 13,32% dan tulang 6,96%. Karakteristik fisik kolagen yang dihasilkan adalah analisis FTIR menunjukkan adanya puncak khas gugus amida (A, I, II, III) yang menandakan keberadaan protein kolagen pada kolagen kulit dan pada kolagen tulang sampel menunjukkan puncak khas gugus amida (A, I, II, III) yang menandakan keberadaan protein kolagen.

Abstract

Enhalus acoroides seagrass has potential as a natural antibacterial agent because it contains flavonoid and alkaloid compounds that can inhibit the growth of Staphylococcus aureus bacteria. This study aimed to formulate and characterize a peel-off gel mask containing E. acoroides extract as a natural antibacterial agent. The research procedures included the extraction of bioactive compounds from seagrass, the preparation of peel-off gel masks with various extract concentrations, and antibacterial activity testing against S. aureus using the disc diffusion method. In addition, pH and homogeneity tests of the formulations were also conducted. The study employed a Completely Randomized Design (RAL) with one treatment consisting of four extract concentration levels, namely 0 mL, 10 mL, 15 mL, and 20 mL, with three replications for each treatment. The results showed that differences in extract concentration had a significant effect (p0.05) on the antibacterial activity of the peel-off gel mask. The inhibition zone diameters ranged from 8.15 mm to 11.80 mm. The homogeneity test indicated that all formulations had a uniform texture without coarse particles. The pH test demonstrated that the mask formulations had a significant effect (p0.05), with pH values ranging from 6.11 to 6.67. These values were within the standard pH range for peel-off gel masks and were considered safe for skin application. Formulations containing 15 mL and 20 mL of extract exhibited the highest antibacterial activity, categorized as strong, with inhibition zone diameters of 10.19 mm and 11.80 mm, respectively. The antibacterial activity was presumed to be associated with the presence of flavonoid and alkaloid compounds that possess bacteriostatic properties. Based on the findings, the peel-off gel mask containing Enhalus acoroides extract has the potential to be developed as a natural antibacterial cosmetic product.
