Abstract

Carrageenan is a non-fish fishery product derived from the extraction of red seaweed (Rhodophyceae) Kappaphycus alvarezii. It is generally used in the field of cosmetics industry, textiles, food, pharmaceutical, stabilizer and gel formation. The objective of this study was to determine the physico-chemical properties of semi refined carrageenan (SRC) on red seaweed (Kappaphycus alvarezii). The research phase included the preparation of raw materials for Kappaphycus alvarezii and making SRC, then followed by physico-chemical analysis, yield, moisture content, ash content, acid insoluble ash content, gel strength, viscosity, melting point, and cumulative point. The Physico-chemical SRC observations were yields of 24.80%, the water content of 19.20%, ash content of 16.34%, insoluble ash content in acid 0.31, the strength of gel 376.46 g/cm2, viscosity 139.47 cP, melting point 55.700C, graduation point 380C.

Abstract

The Anambas Islands have many unique traditional products derived from marine products. One of the famous traditional products is smoked tuna. This study aims to determine the chemical characteristics of smoked tuna processed by smoked fish craftsmen on Jemaja Island, Anambas Islands Regency. This research was divided into three stages, identifying the type of raw materials used, sensory analysis, and proximate analysis. The raw material for smoked tuna is known to come from two types of fish, namely Auxis thazard and Thunnus tonggol. The sensory analysis results with the parameters of appearance, aroma, taste, and texture of smoked tuna from the two raw materials were not significantly different for all parameters. These results are the same as the proximate analysis values which consist of testing the water, ash, fat, protein, and carbohydrate content. Based on the overall results of smoked tuna made from Auxis thazard and Thunnus tonggol it is still by the applicable SNI 2725:2013, except moisture content.

Abstract

Rumput laut Turbinaria decurrens diproduksi masih dalam bentuk kering dan bentuk intermediet. Salah satu cara untuk meningkatkan pengembangannya yaitu diolah menjadi sediaan kosmetik. Selain rumput laut, bahan alam yang dapat digunakan untuk sediaan kosmetik lainnya yaitu kencur (Kaempferia galanga). Tujuan penelitian ini adalah menentukan kombinasi bubur rumput laut T. decurrens dan kencur terbaik sebagai sediaan body scrub berdasarkan hasil aktivitas antioksidan serta stabilitas fisiknya. Penelitian ini dilakukan dengan melihat perbedaan konsentrasi rumput laut T. decurrens dan kencur dengan perbandingan 1:1 (Krim RK1), 1:2 (Krim RK2), dan 2:1 (Krim RK3) dan tanpa penambahan rumput laut dan kencur (Krim RK0). Analisis yang dilakukan mencakup fitokimia, antioksidan, stabilitas sediaan krim dan tipe emulsi. Bubur rumput laut T. decurrens mengandung senyawa alkaloid, flavonoid, tanin dan fenol hidrokuinon, sedangkan serbuk kencur mengandung senyawa alkaloid, dan flavonoid. Bubur rumput laut T. decurrens memiliki aktivitas antioksidan sedang (IC50 119,36 µg/mL), sedangkan serbuk kencur memiliki aktivitas antioksidan sangat lemah (IC50 569,66 µg/mL). Hasil tersebut berbeda dengan aktivitas antioksidan pada sediaan krim body scrub yang mendapatkan aktivitas antioksidan sangat kuat. Nilai IC50 pada formulasi krim RK1, RK2 dan RK3 berturut-turut adalah 1,60±0,12 µg/mL; 1,24±0,15 µg/mL dan 2,49±0,05 µg/mL. Hasil stabilitas sediaan menunjukan krim body scrub memiliki pH seimbang (6,3–7,33) dan aman untuk kulit, Berdasarkan hasil pengujian didapatkan formulasi krim RK2 yang merupakan formulasi sediaan krim terbaik, dilihat dari hasil antioksidan dan stabilitas fisik sediaan krim
