Abstract:
Water guava (Syzygium Samarangense) was a popular plant in Indonesia because it was fresh and sweet. The aim of this research was to analyze the effect of the number of shoots of the upper stems and height of the rootstock at the shoot graft on the percentage of growing water guava. The method used in this study was a completely randomized design, factor into one rootstock length, namely 10 cm, 15 cm, and 20 cm. and the second factor was the number of buds on the scion, namely 2, 3, and 4. The results showed that there was a significant interaction in the treatment combination of the number of 4 buds on the upper stem and the length of the rootstock 15 cm at 35 days after grafting affected the growth percentage and growth in the number of leaves and length of the scion.

Abstract:
Rice is the leading food and a carbohydrate source for most of the world's and Indonesia population, but most rice tends to have a high glycemic index (IG). A product with a low IG is better, not only for people with diabetes but also for healthy people. Resistant starch (RS) functions as a new food ingredient that has a low glycemic index. RS is a part of starch or starch products resistant to digestion when through a gastrointestinal tract. RS has the same physiological effects as dietary fiber, can affect body weight and energy balance, increase lipid excretion to reduce calorie intake and reduce serum lipid levels, zero caloric content so that it can be used as a low-calorie food additive that can control body weight effectively. RS can be made through starch modification by physical treatment (heat treatment), chemical treatment, enzymatic treatment, and a combination of heat and enzymatic. Factors that influence RS's formation include starch properties, starch interactions with other components, processing conditions, heat processes, other treatments, and storage conditions. Therefore, the rice starch modification that contains a lot of RS needs to be known. Rice starch Hydrolysis with the dual enzyme α-amylase and pullulanase (DMT) can increase the highest RS level (51.0%) due to the increased degree of starch crystallinity. High RS results in an increase in gelatinization temperature, ΔH and phase transition temperatures, and a decrease in the speed of starch hydrolysis and weight loss.

Abstract:
Jelly is a candy made from components of water or fruit juice, flavor, sugar, and gelling ingredients. Apart from fruit juice, jelly candy can be made from the basic ingredients of leaf extracts. One of the leaves that can be used is Muntingia calabura L. leaves. The existing jelly candies generally do not use natural ingredients as colorings and flavors. Fruits that can be used as natural ingredients in making jelly candy are Averrhoa bilimbi L. This study aims to determine the effect of adding starfruit extract to the physical quality, shelf life, and organoleptic of Muntingia calabura L. leaves jelly candy. This study used a Completely Randomized Design (CRD) with 1 factor, namely the concentration of Averrhoa bilimbi L extract (0%, 5%, 10%, 15%, and 20%). The results of this study indicate that the addition of Averrhoa bilimbi L extract does not significantly affect the physical quality (color) of Muntingia calabura L. leaves jelly candy. In the shelf life test, the addition of Averrhoa bilimbi L extract gave a real effect, where the best treatment was the concentration of Averrhoa bilimbi L. extract 15% and 20%. In the organoleptic test, the addition of Averrhoa bilimbi L extract did not significantly affect the level of preference (hedonic) and the level of acceptance (scoring) of the texture, but it did affect the level of panelist acceptance of the color, aroma, and taste of Muntingia calabura L. leaves jelly candy. The best treatment of panelist acceptance level for color is at a concentration of 0% producing jelly candy with a yellowish-brown color and the best aroma and taste of jelly candy at a concentration of 20% producing jelly Averrhoa bilimbi L -flavored jelly candy with a slightly bitter sweet taste with a slightly bitter sweetness.
