Abstract

The ohmic technology was applied for the carrageenan extraction process from seaweed (Eucheuma cattoni). The principle of ohmic technology is based on passing an electric current through seaweed and triggering its internal energy. The objectives of this study were to compare two different extraction methods using the ohmic and conventional heaters in terms of the quality of carrageen flour. This study were conducted by two different heating sources during the seaweed extraction process, i.e., ohmic heating and conventional heating from a gas stove. Each method was repeated three times. The extracted filtrates were dried, milled, and sieved using an 80-mesh sieve, then the quality of carrageenan flour was measured. Quality of extracted carrageenan flour using the ohmic and conventional heating methods are: 1) the extraction yield of 45%; 42%, 2) moisture content 10%; 18%, 3) white degree 77.63%; 74.27%, 4) viscosity 6.02 cp; 4.57 cp and 5) gel strength 174 gr / cm2: 159 gr / cm2. The result of statistical analysis between two methods with α 5% showed no significant difference in yield parameters however significantly different for water content, white degree, viscosity, and gel strength. The quality of extracted carrageenan flour of the ohmic heating method was better compared to the conventional heater.

Abstract

The kailan plant (Brassica oleraceae) has high commercial potential due to its high nutritional content, delicious taste, and high market interest. Kailan could be cultivated through hydroponic planting by utilizing limited land. The DFT hydroponic system is an option due to faster and constant growth, shorter harvest period, and easy maintenance. If the power goes out, the plants can still survive. One of the weaknesses is the limited oxygen availability due to poor circulation. This study aimed to determine the effect of using a microbubble generator to enrich oxygen on nutritional conditions and the growth response of kailan plants compared to plant growth without a microbubble generator. The applied method in this study was to compare nutritional content and plant growth responses between using a microbubble generator and without utilizing a microbubble generator. The results showed that using the microbubble generator affected nutrients' concentration, temperature, and pH and positively impacted plant growth responses: number of leaves, root condition and plant weight at harvest period.
