Abstract

Green seaweed is one of the leading marine products from the Riau Islands Province. Types of green seaweed such as Caulerpa microphysa and Codium sp. have potential as functional and pharmaceutical food, but their utilization is not optimal in the Riau Islands region. This study aims to examine the proximate characteristics of seaweed types C. microphysa and Codium sp. The method used in this research is seaweed sampling in the coastal of Natuna and Tanjungpinang, which are the Riau Islands region with abundant green seaweed commodities. The next method is the proximate analysis of dried seaweed, which includes analysis of water content, ash, protein, fat, and carbohydrates and calculating the total energy and energy from fat. The results showed that the proximate content of C. microphysa and Codium sp. respectively for moisture content was 19.88 ± 0.14 and 11.29 ± 0.08%, the ash content was 30.74 ± 0.27 and 55.51 ± 0.41%, protein is 8.97 ± 0.08 and 6.84 ± 0.12%, total fat is 1.20 ± 0.01 and 1.09 ± 0.01%, carbohydrates are 39.22 ± 0.32 and 25.28 ± 0.37%, energy from fat is 10.76 ± 0.06 and 9.77 ± 0.06 Kcal / 100g, total energy is 203.49 ± 1.68 and 138.23 ± 2.02 Kcal / 100g. These results indicate that the type of seaweed C. microphysa is better than Codium sp. in chemical composition and total energy.

Abstract

Research on laboratory scale Spirulina platensis cultivation in Indonesia has developed quite a lot, however, several obstacles occur at harvest time, ranging from high prices and a very long time. Therefore this study aims to determine the effectiveness of the use of electrocoagulation in harvesting S. platensis using different voltage. The research phase included microalgae cultivation, electrocoagulation process, and harvesting of S. platensis, then continued with an analysis of biomass S. platensis, proximate composition, and water quality (pH, temperature, and Ferro (Fe) content). The treatment of electrocoagulation method harvesting of microalgae with voltages 0, 5, 10, and 15 volts (F0, F1, F2, and F3, respectively) were applied in this study. The best biomass harvested with electrocoagulation from F3 treatment was 6.05 gr/L. The proximate content of S. platensis with F0, F1, F2, and F3 treatments were moisture 24.58%, 12.32%, 15.36%, 17.8%, ash 26.56%, 22.42%, 26.53%, 34.99%, protein 34.24%, 30.26%, 25.81%, 21.67%, fat 1.27%, 0.86%, 1.65%, 0.65%, and carbohydrate 13.35%, 34.15%, 30.66%, 25.22%, respectively. The water quality result showed with, F0, F1, F2, and F3 treatments were pH 7, 7, 9, 8, temperature 32°C, 32°C, 32°C, 34°C, Ferro (Fe) 0.1 mg/L, 8.01 mg/L, 12.58 mg/L, 12.29 mg/L, respectively. The best treatment with electrocoagulation method harvesting was F3.

Abstract

One of the typical traditional products from the Riau Islands is “ikan tongkol asap”. These products are spread in several cities and regencies in the Riau Islands Province. Some areas that are famous for producing “ikan tongkol asap” traditionally are Natuna Regency, Bintan Regency and Tanjungpinang City. This study aims to determine the characteristics of “ikan tongkol asap” products based on the type of fish used, chemical composition, and organoleptic assessment. The research was conducted descriptively by taking samples of “ikan tongkol asap” products from several entrepreneurs on Bintan Island (Bintan and Tanjungpinang) and Bunguran Island (Natuna). The research stages were carried out by identifying the fish raw materials used for “ikan tongkol asap” products, morphometric analysis, organoleptic/sensory analysis, and proximate analysis of the product. In this study, it was found that the raw materials used for smoked fish were Thunnus tonggol, Auxis thazard, Euthynnus affinis, and Katsuwonus pelamis. Morphometrically, the fish used were 43.50-46.25 cm in length, and 1.25-1.85 kg in weight. In the sensory analysis with the parameters of appearance, aroma, taste, and texture, the overall products from the three regions were not significantly different. Based on the proximate analysis, each smoked fish product has its own value from each region with crude protein values ​​ranging from 34.04-45.28%. The sensory and proximate are in accordance with the SNI 2723:2013, except for the moisture content of "ikan tongkol asap" E. affinis from Tanjungpinang City and T. tonggol from Bintan Regency.
