This research was designed to evaluate the nutrient content of brown (Laminaria Sp. and Padina australis) and red algae (Eucheuma cottonii and Gracilaria Sp.) from Kelapa beach, Tuban, East Java. The algae were cleaned from dirt and other materials before drying under the sun. All of the algae were ground and analyzed using proximate analysis (dry matter (DM), ash, organic matter (OM), ether extract (EE), crude protein (CP), crude fiber (CF), and nitrogen-free extract (NFE)) and gross energy with a bomb calorimeter. Data were analyzed descriptively by calculating the average of data obtained. The result showed that brown algae of Padina australis had the highest DM (30.59%) and CP (12.57%). The red algae of Eucheuma cottonii had the highest OM (76.58%), EE (2.85%), CF (8.80%), NFE (56.38%), and gross energy (2,911 Cal/g) but had the lowest DM (13.67%) and CP (8.55%). In opposite with Gracilaria sp. had the highest ash (65.63%) and the lowest OM (34.37%), EE (0.21%), CF (2.49%), NFE (19.95%) and gross energy (1,083 Cal/g). Based on this study, brown algae (Laminaria sp and Padina australis) and red algae (Eucheuma cottonii and Gracilaria sp.) have the potential as ruminant feed, especially as mineral and soluble carbohydrate sources.

Abstract. Kustantinah, Hidayah N, Noviandi CT, Astuti A, Paradhipta DHV. 2022. Nutrients content of four tropical seaweed species from Kelapa Beach, Tuban, Indonesia and their potential as ruminant feed. Biodiversitas 23: 6191-6197. Indonesia is one of the tropical countries with the largest diversity of seaweed, but studies on identifying the nutrients content of numerous seaweed species from tropical oceans and their potential as ruminant feed have not been widely reported. This study was designed to evaluate the nutrient, macro and micromineral content of brown (Laminaria sp. and Padina australis) and red seaweed (Eucheuma cottonii and Gracilaria sp.) from Kelapa Beach, Tuban, East Java. All tests were carried out in duplicate from individual seaweed and data were analyzed descriptively by calculating the average of data obtained. The result showed that all of the seaweed species in this experiment had a high content of water (69.41-86.33%) and ash/mineral (23.42-65.63%). The brown seaweed Padina australis had the highest dry matter (30.59%) and crude protein (12.57%). The red seaweed of Gracilaria sp. had the highest ash (65.63%) and the lowest organic matter (34.37%), ether extract (0.21%), crude fiber (2.49%), nitrogen-free extract (19.95%), neutral detergent fiber (21.74%), acid detergent fiber (5.46%), and gross energy (1,083 Cal/g); however, in contrast, Eucheuma cottonii had the highest organic matter (76.58%), ether extract (2.85%), crude fiber (8.80%), nitrogen-free extract (56.38%), neutral detergent fiber (56.93%), acid detergent fiber (11.44%), and gross energy (2,911 Cal/g) but the lowest dry matter (13.67%) and crude protein (8.55%). The brown seaweed Padina australis had the highest Na (0.89%), Mg (4.90%), and Cd (3.73 ppm) contents. The red seaweed of Gracilaria sp. had the highest K (2.18%), Ca (5.80%), Fe (7,596 ppm), Mn (818 ppm), Cu (5 ppm), Zn (52 ppm), and Pb (60.38%); however, in contrast, Eucheuma cottonii had the lowest P (0.01%), K (2.02%), Ca (0.64%), Mg (1.09%), Fe (400 ppm), Mn (38 ppm), Pb (17.31 ppm), and Cd (1.53 ppm) but the highest S (0.46%). Based on this study, brown seaweed (Laminaria sp and Padina australis) and red seaweed (Eucheuma cottonii and Gracilaria sp.) from Tuban Regency, East Java, Indonesia have the potential as ruminant feed, especially as soluble carbohydrates and an organic mineral source that requires attention for heavy metals to prevent toxicity to ruminants.

“…Metode ekstraksi dan jenis pelarut yang digunakan sangat mempengaruhi kandungan senyawa dominan dan aktivitas biologisnya. Hasil penelitian [21] menunjukkan bahwa ekstraksi Gracilaria sp. menggunakan pelarut etanol memiliki aktivitas antioksidan paling besar dengan nilai IC50 22,15±1,63 µg/mL dibandingkan dengan pelarut etil asetat dan n-heksana.…”

KANDUNGAN TOTAL FENOL DALAM EKSTRAK METANOL DAN ETIL ASETAT Caulerpa racemosa (TOTAL PHENOL CONTENTS IN METHANOL AND ETHYL ACETATE EXTRACTS OF Caulerpa racemosa)

et al. 2022

View full text Add to dashboard Cite

Caulerpa racemosa belongs to Chlorophyceae grow abundantly along Indonesian waters, including Kabung Island, West Kalimantan. This species has important role and is able to synthesize a wide range of bioactive compounds that are potential to be developed. However, their existence have not been used optimally. This study aims to determine the bioactive compound and evaluate total phenol contents in methanol and ethyl acetate of C. racemosa from Kabung Island. The methods in this study were maceration, phytochemicals, and Folin-Ciocalteau using Atomic Absorption Spectroscopy (AAS). The result showed that methanol and ethyl acetate extracts of C. racemosa contained alkaloids, flavonoids, saponins, phenols, and tannins. Thus, the total phenol content in ethyl acetate extracts was 0.077817 mgGAE/g while in methanol extract was 0.05682 mgGAE/g, respectively. This value was classified as low category.
