Abstract

Addition of the substance will effect the value of carbon equivalent (CE) cast iron. Carbon equivalent value is a parameter that tells us how much carbon is cointained in the cast iron. Carbon equivalent values were determined between 4,7 to 4,9. When the carbon equivalent (CE) on the cast iron is less than 4.7 to 4.9 then it will be easy to cast iron, causing cracks in the baked anode rod will come loose. And usage cast iron is not optimal. And when more than that value so cast iron will difficult loose from the anode rod. From the observations that have been made obtainable carbon equivalent (CE) cast iron are 3,76 and 4,7. This indicates that the value of carbon equivalent (CE) cast iron still eligible and meet the standars that have been established which is between 4,7 to 4,9.

Abstract

The noodle circulating in the market and which we often consume the main ingredient is wheat flour so that the nutrient components such as fiber and carotenoids contained in noodle is very minimal. To increase the content of fiber and carotene noodle it is necessary to substitute flour with local food containing fiber and carotenoids. For example breadfruit and pumpkin. This study aims to determine how the influence of the amount of pumpkin paste and breadfruit as the substitution of flour to the characteristics of wet noodles and to the color preferences test and to determine the effect of storage duration on carotenoid content of wet noodles. The experiment was conducted by non factorial randomized design by comparing the amount of pumpkin paste to breadfruit paste and storage duration. The results showed that water content, ash content and protein content were not influenced by the ratio of the number of pumpkin paste to breadfruit paste. But the fiber content increased from 1.22% to 3.16% and carotenoid levels from 0.07 ppm to 0.10 ppm. The color preference level increases from 1.86 (dislikes) to 3.35 (like). Time storage can lower carotenoid levels from 0.105 ppm at 0 days storage to 0.08 ppm at 4 days. The conclusion of flour substitution with breadfruit paste and pumpkin paste can increase the fiber content and wet carotenoid noodles. Storage results in decreased carotenoid levels.

Abstract

Fruits are not always consumed in fresh form. But most are processed into various forms and types of food. This treatment aims in addition to extending the shelf life, as well as to increase the variety of products. Fruits are generally processed into preparations such as jam, jelly, jam, puree, fruit juice, canned fruit, candied dry or wet. One type of dried fruit products other than candied fruits is Fruit leather. Fruit leather is a type of food of fruit flesh that has been destroyed and dried. Drying can be done with drying or it could be with a warming that has a hot temperature of 50-60oC. Fruit leather has a shelf life of up to 12 months, when stored at appropriate storage conditions. In Indonesia, Fruit leather is still not commercially produced. Rossela contains some substances that are very important for health. Including grossy peptin, antochanin, gluside hibiscin, and flavonoids that are useful to prevent cancer, control blood pressure, blood circulation and so forth. The fiber content is high enough that plays a role in launching the exhaust system and lower cholesterol levels in the blood (Erianto, 2009). Based on this background then this study was conducted to combine the mango fruit is known to have high nutritional content with rosella flowers that have some substances that are very important for health. Implementation of Research using Factorial Random Design (RAL), with two main factors that is: Factor I: Varieties of mango fruit (M) consisting of 3 levels: M1: Mango shrimp, M2: sweet sweet Mango, M3: Kueni. Factor II: Addition of rosella (%) of mango flesh, consisting of 4 levels: R1: 40%, R2: 60%, R3: 80%, R4: 100%. The study was conducted with 3 replications. The research was conducted from April to May 2017 at the laboratory of Agricultural Product Technology Faculty of Agriculture UISU Medan. The results showed that the best treatment combination was obtained in Kueni mango with 40% rosella flower meat (M3R1). The strong aroma and taste of Kueni produce the fruit leather with the highest organoleptic value of the color scent. Conversely, the higher percentage of rosella addition resulted in organoleptic assessment of flavor, color and flavor decreased.

Abstract

Kombucha rosella tea is processed from a mixture of traditional black tea and rosella tea using by the "kombucha culture".  To extend the shelf life is made into an encapsulation form. The benefits of kombucha rosela tea is as functional food and has been widely consumed by the community, therefore required a more scientific study. This research consisted of two factors: four rosella tea percentage levels were 20, 40, 60 and 80% with four fermentation time levels of 5, 6, 7 and 8 days, using factorial completely randomized design. The parameters analyzed were moisture content, vitamin C content, total acid, water solubility, tannin content, anthocyanin levels and organoleptic value (colour, flavour and taste). The results showed that the concentration of rosella tea and fermentation time had a significant effect on all parameters. Interactions of the two factors had highly significant effect on total acid and had significant effect on tannin content. Rosella tea concentration of 80%  for 8-days fermentation time resulted in the highest levels of vitamin C of 330.0 mg/100 g, anthocyanin of 348.430 mg / L, tannin content of 2.170% and the best of panel quality.
