Abstract

Siput laut gonggong asal Bintan merupakan salah satu gastropoda laut yang belum dimanfaatkan secara optimal. Siput ini merupakan makanan laut khas Bintan dan harganya sangat mahal. Secara empiris, siput ini dipercaya dapat meningkatkan stamina dan vitalitas. Tujuan penelitian ini adalah untuk melakukan penapisan senyawa bioaktif pada siput laut gonggong asal Bintan yaitu aktivitas antioksidan dan aktivitas antimikroba. Aktivitas antioksidan dianalisis menggunakan metode DPPH dan aktivitas antimikroba dianalisis menggunakan metode difusi sumur. Aktivitas antioksidan ekstrak gonggong bercangkang tipis dengan IC50 1.433,08±0,01 ppm lebih tinggi daripada gonggong bercangkang tebal dengan IC50= 2.051,55±0,10 ppm. Aktivitas antimikroba pada ekstrak gonggong lebih baik pada bakteri Gram positif daripada bakteri Gram negatif. Ekstrak gonggong rebus bercangkang tebal memiliki aktivitas antimikroba yang paling tinggi dengan nilai rata-rata diameter daya hambat (DDH) yaitu 25,53±0,12 mm.

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.
