Abstract

The consumption effect of gel and solution of Eucheuma cottonii seaweed on blood lipid level were studied on hypercholesterolemic male wistar rat. The rat were made hypercholesterolemic by a ration that contained high lipid and cholesterol, and then they were given standard ration orally and 10, 15, and 20 % (w/w feed) of gel and solution seaweed parenterally. The results show that the standard ration could not reduce hypercholesterolemic to normal level while gel and solution of the seaweed could. The gel type of the seaweed has higher capacity decrease of cholesterol and triglyceride blood level. The consumption of seaweed gel 20 % and 15 % could reduce cholesterol to normal level in 9 and 15 days, respectively, while the solution type 20 % needed 18 days. The seaweed gel 10 %, solution 15 % and 1% could reduce blood cholesterol level, but they could not reach to normal level in 18 days.Key words : cholesterol, gel, rat, solution, seaweed

Abstract

The effect of kappa-carrageenan consumption on blood glucose level were studied on diabetic male wistar rat (Ratus norvegicus).The rats were made diabetic by aloxan injection, and then were given that a ration contains 5, 10, 15, 20% (w/w ) kappa-carrageenan, standard ration (negative control), and parental glibenklamid (positive control). The results showed that the standard ration could not reduce blood glucose from hyperglycemic to normal level, while the ration contained kappacarrageenan could. The higher kappa-carrageenan seaweed level in the ration has higher capacity to decrease blood glucose level. The ration containing 20% and 15% kappa-carrageenan could reduce blood glucose in 18 and 21 days, respectively.The effect of this ration was similar to that of glibenklamid which reduced blood glucose to normal level in 18 days. The ration containing 5 and 10% kappa-carrageenan could reduce blood glucose level; Blood glucose leve return to normal on the 21st day. Key words: blood glucose, kappa-carrageenan, glibenklamid.

Abstract

Fermentation is one of the methods to get noni juice. In this research, noni is fermented in hanged system and submerged system for 1, 2, 3, and 4 weeks. The result showed the longer fermentation increased pH, alcohol content, turbidity, viscosity, microbial content, and decrease ascorbic acid and acid content, soluble solid content, color and flavor acceptance. Differennt system fermentation affected percent yield, soluble solid content, turbidity of juice, panels opinion to color significantly. Noni juice of submerged system has higher percent yield, higher soluble solid content, turbidity, but provided lighter color than noni juice of hanged system. Juice of submerged system is better than hanged system. Juice from three weeks fermentation indicated changes of metabolism activity which is shown by some characteristic changes. Fruit juice made by submerged fermentation system had more diverse compounds than fruit juice without fermentation. Key words : Noni juice, fermentation.

Abstract

Southern Waters of Java Island are 573 fisheries management zones, the Big Eye Tuna (Thunnus obesus) commodity is one of fish that has high economic value. There are oceanographic factors affect fish distribution of Big Eye Tuna (Thunnus obesus) such as sea surface temperature, chlorophyll-a, and depth. The data research of Big Eye Tuna fishing zone was obtained from PPSC with data description were year, month, day, number of trips, and number of fish caught around 2018-2019. Oceanographic data used from citra satellite Aqua MODIS for sea surface temperature and chlorophyll-a, and citra satellite ETOPO-1 for depth, by using GAM statistical analysis by looking at the lowest AIC value and the largest CDE value of 7 combined models of oceanographic parameters. The results obtained from statistical analysis using the GAM which was very influential in determining the potential zone for the fishing of Big Eye Tuna (Thunnus obesus) showed that a combination of sea surface temperature + chlorophyll - a + depth with an AIC value of 28840.02 and CDE of 11.1%, with the results Oceanographic parameters optimum sea surface temperature was 25 ° C- 30 ° C, for chlorophyll - a 0.08 - 0.30 mg / m3, and for an average depth of 3500m. The depth parameter had a less positive influence because the Cilacap fishermen used FADs for the fishing area of Big Eye Tuna. The distribution area of Big Eye Tuna (Thunnus obesus) in the Southern of Java Island is at latitude (-7.3 °) - (-14.83 °) and longitude 102 ° - 115.25 °.
