Efforts to lower blood sugar levels for diabetes mellitus patients can take by consuming  a popular functional drinks which has been added by herbal ingredients such as breadfruit leaves. The aim of this research is to observe the effect of addition three-types of sweetener (aspartame, acesulfam k, and sorbitol) in different ratio (50%: 25%: 25%, 25%: 50%: 25%, 25%: 25%: 50%) to the antioxidant capacity and glucose level of functional drinks made from breadfruit leaves, as well as its number of calories and variety sensory tests (sour taste, sweetness and texture). The experimental design used a Completely Randomized Design with three replications. This study also employs 35 panellists to produce organoleptic quality data in two repetitions.  All collected data were then analyzed using ANOVA test followed by DMRT test. Results showed that the highest antioxidant capacity was obtained by ratio 25%: 25%: 50% of aspartame, acesulfam k, and sorbitol with IC50 value of 64,717 ppm. Meanwhile the lowest glucose level was resulted by ratio 50%: 25%: 25% of aspartame, acesulfam k, and sorbitol in value of 25.53 g/100g. The highest number of calorie was produced by ratio 25%: 25%: 50% of aspartame, acesulfam k, and sorbitol with a value of 126.44 cal. / 100gr. Whereas, the most preferred formulas of breadfruit drink formulas are found in ratio 25%: 25%: 50% of aspartame, acesulfam k, and sorbitol.

ABSTRACTEucheuma cottonii (E. cottonii) seaweed is a low level plant that has a high nutritional value. One of the ingredients that play a role in the formation of texture is carrageenan.Carrageenan is a type of hydrocolloid extracted from the seaweed of the red algae group (Rhodophyceae). The purpose of this study was to determine the quality of yields of Seaweed Carrageenan Extract (E. cottonii) obtained from Tablolong beach in the form of yield, ash content and fat content. The method used in this study is an experimental method with a completely randomized design (CRD) and for fat testing using quantitative descriptive methods. This study uses various concentrations of 0.1 N KOH, 0.2 N KOH, 0.3 N KOH and 0.4 N KOH. The results of the carrageenan yield test show that the addition of 0.1 N KOH concentration has a value of 56.10, KOH 0 , 2 N 62.16, KOH 0.3 N 72.73 and the best treatment was at P4 KOH 0.4 N 80.90. Carrageenan ash content test results showed that the addition of KOH concentration value obtained P1 KOH 0.1 N was 60.50, P2 KOH 0.2 N was 70.70, P3 KOH 0.3 N was 80.50, and P4 KOH 0.4 with a value of 90.50. The results of the carrageenan fat content of 0.1 KOH treatment has a fat content of 0, 2 while the treatment of KOH 0,2, KOH 0,3, KOH 0,4 have no fat content by showing the value (0). The results showed that the highest yield in the treatment of KOH concentration of 0.4 N with a value 80.95% and carrageenan ash content has the highest value in the treatment concentration of 0.4 N with a value of 90.50% while the fat content has a value of 0.2 in the treatment of KOH concentration of 0.1 N Keywords: Carrageenan, extract of E. cottonii seaweed.

Rice bran and red beans are one of food items that contain high dietary fiber and can be processed into traditional snacks such as baked getuk (cassava cake). Elderly needs enough fiber to support their metabolism. This study aims to analyze the effect of rice bran and red bean substitution of getuk toward its acceptance and dietary fiber contents. This study was an experimental study with a completely randomized design. There were four treatments of rice bran and red beans substitution (F0 = 0% rice bran, 0% red beans); (F1 = 10% rice bran, 13% red beans); (F2 = 13% rice bran, 10% red beans), (F3 = 17% rice bran, 7% red beans). This study further involved 30 untrained elderly and pre- elderly panelists (45–80 years). Acceptance was measured using a hedonic questionnaire on a scale of 1 to 6. Statistical analysis of acceptability differences was completed using Kruskal-Wallis and Mann-Whitney test with α ≤ 0.05. In results, there were significant differences between F1, F2, F3, and F0 on all characteristics (color, aroma, texture, taste) with p = 0.001, and the acceptance rating from highest to lowest was F3, F2, F1, respectively. The organoleptic test results further showed that the panelists mostly preferred the F3 formula (17% rice bran and 7% red beans). There was no significant difference in dietary fiber content between each formula, F1 contains 9.250 grams of dietary fiber (30.8% RDA), F2 contains 9.242 grams of dietary fiber (30.8% RDA), and F3 contains 9.235 grams of dietary fiber (30.7% RDA). This study proved that rice bran and red red beans substitution to getuk improves its fiber content and also having good acceptability.
