Year: 2025
Type: conference-paper
Abstract: This study aimed to evaluate the diversity and nutritional content of red macroalgae in Kupang Bay, Indonesia. Sampling was conducted during low tide at five research stations: Paradiso Beach, Kelapa Lima, Pasir Panjang, Bolok, and Tabulolong. Red algae were collected and documented for identification within a 1 × 1 m area at each station. After identification, the macroalgae were cleaned and dried for nutritional analysis, including proximate composition, amino acid content, and mineral levels of calcium, iron, and potassium. A total of 12 species of red macroalgae were identified in Kupang Bay. Their protein content ranged from 4.38% to 14.85%, fat content from 0.37% to 1.41%, and carbohydrate content from 30.21% to 42.92%. The red macroalgae contained 15 amino acids, with variations in their properties. Gracilaria curticata, Acanthophora specifera, Gracilaria filamentosa, and Halymenia sp. exhibited high glutamic acid levels at 1.45%, 1.59%, 1.08%, and 1.22%, respectively. Additionally, Acanthophora fragilissima was notable for its high methionine content (0.82%).
