PENGARUH PROPORSI BERAS SEJAHTERA DAN SAWUT SINGKONG TERHADAP MUTU NASI SAWUT: The Effect of Prosperous Rice and Shredded Cassava Proportion on the Quality of Shredded Cassava Rice
Full text linkABSTRACT
The purpose of this study was to determine the effect of proportion of “Rastra” (Prosperous Rice) and shredded cassava on the quality of shredded cassava rice. The method used was experimental method in laboratory and designed using Randomized Block Design (RBD) with a single factor i.e. proportion of prosperous rice and shredded cassava. The treatments of rice and shredded cassava proportions were consisted of 100%: 0%; 80%: 20%; 60%: 40%; 40%: 60% and 20%: 80%. Chemical and organoleptic data were analyzed using analysis of variance (ANOVA) at 5% significance level using Co-stat software. The significant difference data were tested by a real difference test with honestly significant difference test, while the microbiological data were analyzed with a descriptive method. The results showed that the proportion of prosperous rice and shredded cassava had a significantly different effect on chemical quality (moisture content and ash content) and organoleptic quality (color, taste and texture) but did not significantly affect on organoleptic quality (aroma) and total microbes. 60% of prosperous rice and 40% of shredded cassava was recommended as the best proportion to produce shredded cassava rice with characteristic yellowish white, odorless smell, fluffy texture and taste of rice and has a water content of 66.02%, a value of 0.13% ash and microbiological quality that has met the SNI standard 7388: 2009 with a total microbe of 3.3x105 CFU / g, total mushroom 7,2x102 CFU / g and total coliform 27 MPN / g.

Horn plantain and soursop are horticultural products of climacteric fruits that contain high nutrition and fiber, but have a relatively short shelf life after harvest. One solution so that both of them can still be consumed by maintaining their nutritional and fiber content is making sheeted jam. This study aims to determine the ratio of puree horn plantain and soursop, and to determine the ratio of carrageenan:konjac hydrocolloid and the concentration of hydrocolloid in the making of fiber source sheet jam. Initially, horn plantain and soursop were made into a puree (ratio of horn banana puree : soursop = 1:0, 3:1, 1:1, 1:3, and 0:1). The 1:3 ratio was chosen as the best ratio (fiber content of 5.82%) and was subsequently used in the determination of the hydrocolloid ratio of carrageenan: konjac (1:0, 1:1, and 1:2) and the concentration of hydrocolloid (1.0; 1.5; and 2%). A ratio of 1:1 with a concentration of 2% hydrocolloid produces the best sheeted jam based on dietary fiber content of 5.60%; syneresis 0.28%; pH 3.43-3.62; total dissolved solids (TDS) 33.73-34.87° Brix; hardness 671,74 g; water 45.79%; ash 0.08%; fat 0.05%; protein 0.35%; carbohydrates (by difference) 53.73%; and still accepted by consumers with the overall hedonic value (4.91 on a scale of 7.00 [neutral]).

Water Kefir
Full text linkABSTRACT
Yellow watermelon (Citrullus lanatus (Thunb.)) is a kind of horticulture commodity that contains high water content. There are three parts of yellow watermelon, namely the outer part (exocarp), the middle part with white color (mesocarp), and the fruit flesh (endocarp) that the mesocarp often becomes waste of the consumption of yellow watermelon. One of the development innovations for yellow watermelon is to process it into fermented beverage such as water kefir using the mesocarp so that there is no waste material. This research aims to know the effect of mesocarp concentration on yellow watermelon water kefir physicochemical and microbiology characteristics. The method of research was using Completely Randomized Design with one factor (mesocarp concentration). Treatment variation which is utilized the 0% (v/v), 5% (v/v), 10% (v/v), 15% (v/v), and 20% (v/v) of mesocarp concentration. The research results show that the higher mesocarp concentration can increase the total of lactic acid and lactic acid bacteria, decrease the alcohol content and total of yeast, contribute to give antioxidants on water kefir, and mesocarp concentration does not have a real impact on viscosity.
