Abstract

Seaweeds have potential uses as functional foods. But until now, there is still few information about the nutritional composition of seaweeds, especially from Teluk Sepang Beach, Bengkulu City. This study was held to examine the chemical characteristics of brown and red seaweeds from Teluk Sepang Beach, Bengkulu City. This research was carried out in November 2021-March 2022. This research used descriptive exploratory method by analyzing the proximate composition of 8 species of seaweeds (4 species of brown seaweeds and 4 species of red seaweeds). Water, protein, crude fat, ash and crude fiber content refer to the AOAC (2016) procedure while carbohydrate content is calculated based on by difference. The chemical characteristics of seaweeds (water content, ash, crude protein, crude fiber, crude fat and carbohydrates content) varied from one species to another. But in general the proximate composition of all seaweeds species was still in the range of values ​​found in seaweeds. The largest composition in seaweesd is carbohydrates (13.644% - 69.91±0.71%) and ash, which have an important role for humans nutrition and the food industry. The content of protein (0.97±0.33%. - 2.88±0.23%) and crude fat (0.19±00% - 4.12±0.32%) in seaweeds is relatively low so it can be used as low fat foods. Crude fiber in seaweeds(1.16±0.16% - 7.65±0.53%) showed that seaweeds can be used as functional foods.

Abstract

This study aims to identify the type and analyze the density of the Caulerpa sp. at Sepang Bay Beach, Bengkulu City. This research was conducted in July-August 2020. The research method used a survey method. The data collected in this study are primary data and secondary data. The observed water quality, such as the temperature obtained at the time of the study, was 30-31oC, pH value was 7.7-7.8, brightness ranged from 0.5–0.68 meters. Three species of Caulerpa sp. were found in Teluk Sepang Beach, Bengkulu City with each relative density value, namely Caulerpa taxifolia (46.6 ind / m2), Caulerpa racemosa (52.1 ind / m2) and Caulerpa lentillifera (1.2 ind / m2)).

Abstract

Percobaan pembenihan Kobia (Rachycentron canadum) selama empat puluh lima hari dilakukan untuk menentukan kebutuhan imunostimulan yang ditambahkan dalam formulasi pakan mandiri. Tiga diet praktis isonitrogen dan isoenergik (CP 42% dan lipid 11%) mengandung tiga tingkat imunostimulan tambahan yaitu 0,0%: 0,3% dan 0,5%. Setiap perlakuan diet secara acak diberikan ke tiga tangki dan pakan diberi sampai kenyang dua kali sehari. Kobia dengan berat awal 50 g ditebar di tangki ber aerasi dan air mengalir dalam ruangan. Pengukuran dilakukan pada pertumbuhan dan kekebalan non-spesifik benih kobia. Hasil penelitian menunjukkan bahwa tidak ada perbedaan pertumbuhan yang signifikan diantara perlakuan. Uji fagositosis dan uji tantangan pada pengobatan pemberian pakan tambahan menunjukkan bahwa penambahan imunostimulan 0,3% dalam praktik formulasi pakan dapat meningkatkan kinerja kekebalan tubuh.
