Abstract

Coral reef ecosystems are vulnerable to damage. The rehabilitation process naturally takes a long time. This study aims to determine the growth rate and survival of Euphyllia paradivisa corals ex-situ at PT Agung Aquatic Marine, Bali. Seawater used in the aquarium has very maintained water quality to keep the corals alive even though they are outside their natural habitat. This research employs an experimental method, with data analysis conducted using the independent sample T-test. We collected data eight times, once every two weeks for four months. Each of the six aquariums, comprising three with sunlight treatment and three with LED light, houses 10 transplanted corals. A caliper is used to measure the width and height of the corals. The growth rate of Euphyllia paradivisa corals under different treatments (sunlight vs. LED light) was determined by analyzing the results. There is a significant difference in the width and height of Euphyllia paradivisa corals. The growth rate of Euphyllia paradivisa corals in ex-situ under the treatment of sunlight is 0.016 mm wide and 0.017 mm high per month, and then in the treatment of LED light, the growth rate of Euphyllia paradivisa corals in ex-situ is 0.009 mm wide and 0.007 mm high per month. The growth rate of Euphyllia paradivisa corals in ex situ with sunlight treatment is better than LED light treatment.

Abstract

This study was conducted to determine the effect of different culture media on the growth of Tetraselmis chuii. This study used the experimental method. The treatments used in this study were P1 (GRIM Standard), P2 (GRIM+Clewat-32), P3 (Jasfa Yaeyama), and P4 (GRIM KNO3 Clewat-32). The experimental procedure consisted of a pre-research process to observe and calculate the population density and cell size observation of Tetraselmis chuii. The results showed that different culture media affected the population density of Tetraselmis chuii. Optimum growth was obtained in the culture medium GRIM + KNO3 Clewat-32, reaching 30.3× 106 cells/ml. One-way ANOVA test with a significance level of 95% showed that the difference in media had a significant effect on the growth of Tetraselmis chuii with a value of F = 1.09, P < 0.05. The results of the Duncan test showed that cell density in media A (Grim Standard) was significantly different from media treatments C (Jasfa Yaeyama) and D (GRIM KNO3 Clewat-32). Still, treatment A was not significantly different from treatment B (GRIM Clewat-32), nor was treatment B significantly different from treatments C and D. The cell size of Tetraselmis chuii at the time of the study in all treatments obtained an average value of 6.84 - 11.55 µ. The water quality required for T. chuii is suitable for culture media.

Abstract

Blood glucose is a term that refers to the glucose level in the blood. The food type and physiological functions of the body can increase blood glucose. The right food can maintain stable blood sugar. One food source that can maintain stable blood sugar is tubers. One of them is daluga tubers which have a low glycemic index value. This study aims to determine the effect of giving composites made from daluga tubers for 42 days on the blood glucose levels of white rats (Rattus norvegicus). This study used a completely randomized experimental design with nine treatments and three replications. An experimental animal was given 30 g of food each day for 42 days based on the group of treatments. The drinking water was given ad libitum. Blood glucose was measured on days 21 and 42. The results showed that providing daluga-based composite feed to mice affected blood glucose levels (p<0.05). The feeding treatment was 100% composite 3 consisting of 30% daluga flour, 40% rice flour, and 30% corn flour, a daluga-based food can potentially be a food ingredient that can maintain stable blood glucose levels. So it can be concluded that composite 3 could be safe to consume by the diabetes patient.
