Abstract

ABSTRACT The aim of this study was to examine the formulation of meat snail and porang flour on physical characteristics and sensory acceptance of the meatballs. The design used in this study was a Randomized Block Design (RBD) with 2 treatments, namely the concentration of meat snails and the concentration of porang flour in making meatballs. The treatment of meat snail concentration is 0%, 20%, 40% and 60% while for porang flour concentration is 0% and 0.3%. Each experiment was repeated 3 times so that there would be 24 units of trial units. Physical and sensory quality data obtained were analyzed using SPSS with a 5% BNJ level of significance. Concentration of meat snail has significant effect on physical quality (texture, color (L, a and b)) and sensory quality (color and hedonic texture. Porang flour concentration significantly influences physical quality (colors L and b). Interaction of treatment between the concentration of meat snail and the concentration of porang flour significantly affected physical quality (colors a and b) and the sensory quality of texture hedonically. Treatment of 20% meat snail concentration with the addition of porang flour 0.3% is the best treatment. Physical quality values are best treated for texture 3.38 N, color L 42.46, color a 2.92 and color b 16.31. Sensory quality values are best treated for color is rather like and texture likes.

Rancangan yang digunakan pada penelitian ini adalah Rancangan Acak Kelompok (RAK) dengan 2 perlakuan yaitu konsentrasi daging keong sawah dan konsentrasi tepung porang pada pembuatan bakso. Perlakuan konsentrasi daging keong sawah yaitu 0%, 20%, 40% dan 60% sedangkan untuk konsentrasi tepung porang yaitu 0% dan 0,3%. Masing-masing percobaan diulangi sebanyak 3 kali sehingga diperoleh satuan percobaan sebanyak 24 unit percobaan. Data mutu fisik dan sensoris yang diperoleh dianalisa menggunakan SPSS dengan taraf nyata BNJ 5%. Konsentrasi daging keong sawah berpengaruh nyata terhadap mutu fisik (tekstur, warna (L, a dan b)), dan mutu sensoris (warna dan tekstur secara hedonik). Konsentrasi tepung porang berpengaruh nyata terhadap mutu fisik (warna L dan b). Interaksi perlakuan antara konsentrasi daging keong sawah dan konsentrasi tepung porang berpengaruh nyata terhadap mutu fisik (warna a dan b) dan mutu sensoris tekstur secara hedonik. Perlakuan konsentrasi daging keong sawah 20% dengan penambahan tepung porang 0,3% merupakan perlakuan yang terbaik. Nilai mutu fisik diperlakuan terbaik untuk tekstur 3,38 N, warna L 42,46, warna a 2,92 dan warna b 16,31. Nilai mutu sensoris diperlakuan terbaik untuk warna agak suka dan tekstur suka.

Abstract

Ice cream is a kind of dessert with a sweet taste and served in a cold and frozen. Ice cream has a soft texture, to make the texture required stabilizer, which is one of the ingredients added in the manufacture of ice cream in order to prevent crystallization, as a binder and improve the texture. Stabilizers can be met from starch-based materials of local potency of tubers. Gelatinization of starch in the tuber flour can replace the function of the stabilizer. Some types of tubers that can be developed as an alternative source of natural stabilizer such as porang, uwi, and taro. The study is entitled "The Effect of Adding Natural Stabilizer Based on local tubers for Improving physical and chemical properties of Red Dragon Fruit Ice Cream(Hylocereus polyrhizus sp)". This study aims to examine the effect of local tubers (lombos,flour (porang), uwi flour and belitung taro flour) as a stabilizer on manufacture dragon fruit ice cream. The research will be done first with the preparation stage which is the manufacture of tuber flours (porang, uwi and Belitung taro). Implementation of the research was conducted in two stages are 1) making dragon fruit ice cream with tuber flours; 2) determining the best treatment of the use of stabilizer from the tubers. The tests include the physical and chemical quality that has been performed in the Quality Control Laboratory, the Chemical Laboratory and the Food Biochemistry and the Food Processing Laboratory. Parameters observed in this study include moisture content, total dissolved solids, melting time, emulsion stability, and texture. Based on the results of the research known that the best treatment is the use of porang stabilizer with 0.5% concentration in the manufacture of red dragon fruit ice cream. The treatment is able to match the ability of CMC as an ice cream stabilizer. In the treatment porang 0.5% obtained water content 64.39%, total soluble solids 14.80%, emulsion stability 87.41%, and melting time 95.45 minutes / 100 grams.
