ABSTRACTPumpkin (Cucurbita moschata (Duch.) Poir ) is one of the vegetables that is rich in β-carotene as a precursor of vitamin A and has a fairly high carbohydrate content. Pumpkin processing can be done to produce various kinds of products, one of which is cake. Cake is a baked dough and liquid dough made from flour, sugar, salt, ingredients, shortening, milk, eggs, and aroma enhancer. This study aims to determine the levels of β-carotene contained in pumpkin cake and to determine the acceptability of β-carotene in pumpkin cake. This research is an experimental research. The experimental design used was Completely Randomized Design (CRD) with 1 control 4 treatments and each treatment was repeated 3 times. The research phase consisted of making flour and making cake. Data collection methods include organoleptic tests and β-carotene tests. Data were analyzed using analysis of variance / ANOVA to determine differences in quality, and if there is an influence then proceed with the Tukey test. Organoleptic test results show that the best treatment of pumpkin cake in terms of color is A1 with a value of 3.88, in terms of aroma namely A0 with a value of 3.92, in terms of texture is A0 with a value of 4.28 and in terms of taste is A0 with value of 4.16. As for the β-carotene test, the treatment of pumpkin cake with the highest β-carotene content was found in A4 with an average of 0.262 and the lowest level was in A0 with an average of 0.018. Based on research data, pumpkin flour is worthy of being used as an alternative source of flour because the resulting cake meets SNI quality standards both in terms of color, taste, aroma, texture and β-carotene content.Keywords : Cake, Pumpkin, β-Carotene, Organoleptic

Not infectious disease (PTM) have become a health problem for every country. One of the main contributors who use PTM is food control, by consuming foods that contain inulin (bengkuang tubers) and anthocyanins (dragon fruit). Intermittent food products consisting of velva become more effective because in one product already has a lot of special nutritional content of inulin and anthocyanin fibers. The design of this study was experimental with a completely randomized design (CRD). The research method uses hedonic tests, spectrophotometry for anthocyanin levels, and literature tests for inulin fiber levels. This study involved 30 panelists who were apparently students of the Nutrition Department of the Poltekkes Bandung. This product formulation consists of three dragons and bengkuang, which is counterpart 1 (30%: 70%), counterpart 2 (70%: 30%), and counterpart 3 (50%: 50%). The hedonic test results showed that the level of preference consisted of counterpart 2 and the Kruskal-Wallis test results showed differences between the aspects of color, taste, and aroma with a value of p <α and also none in the design of the texture with p> α. The level of anthocyanin product serving is 6.04 mg and can fulfill 81% of the anthocyanin requirement by consuming two serving sizes. While the level of inulin per serving amounted to 2.1 g and can meet the needs of inulin at least a day from 350% snack.

        Duck eggs  that are often processed into salted eggs. But now it is necessary to look for other alternatives from processing these duck eggs with different tastes, besides taste salty there is also a sense of smoked.This study aims to analyze the effect of fumigation media on the exterior quality and organoleptic of salted smoked eggs. The method was used an experimental method. Fumigation was carried out 48 hours for each fumigation media. The research method used a Completely Randomized Design (CRD) with five treatments and four replications (5x4) in a total of 20 research units consist of m0 = no fumigation (control), m1 = fumigation media using coconut fiber, m2 = fumigation media using sawdust, m3 = fumigation media using rice husk, and m4 = fumigation media using galam bark. Exterior quality data obtained were carried out by homogeneity test data and ANOVA. If the analysis of variance is significantly different or very real it's done by means of the middle value test using the Duncan Multiple Range Test (DMRT). While the analysis of the organoleptic test results obtained was performed using the Kruskal Wallis test then Duncan Multiple Range Test (DMRT). The results showed that the fumigation media effected to the sand and the typical aroma of salted smoked eggs. The fuming media acts on the weight reduction of salted smoked eggs. Galam bark fuming media and coconut fiber has the highest sandiness among other media. However, the smoked media from galam bark had the biggest egg weight shrinkage.
