Chips are classified as types of snacks that are categorized as crackers, foods that are dry, crisp (crispy). In general, the manufacture of chips is by way of direct material cut so many consumers who do not love because they do not obtain the desired level of crispness. It is therefore necessary to add starches such as tapioca to improve the crispiness of the chips. In this study, sweet potato being processed first and the addition of starch such as tapioca to increase the crispiness. But the addition of starch is not more than 30% by the weight of sweet potato dough for undesirable development of large volumes such as chips which are made by flour. The addition of tapioca starch will also affect the physicochemical and organoleptic properties of the chips. The study was conducted to determine the effect of tapioca proportion to the physicochemical properties and organoleptic orange sweet potato chips. The study design used is Random Group non factorial. Factors studied were concentration of tapioca which consists of 7 (seven) standard of treatment in the form of 0% (w / w); 5% (w / w); 10% (w / w); 15% (w / w); 20% (w / w); 25% (w / w); 30% (w / w), with a repeat of four (4) times in order to obtain a total of 28 experimental units. The use of the higher tapioca starch increases the water content of the raw chips, volume expansion, oil absorption and lightness, while the water content of the cooked chips, redness, yellowness, chroma and texture decreases. The results showed that the best processing is the concentration of tapioca 30% with the moisture content of 7.61% raw chips, cooked chips water content of 2.91%, volume expansion of 57.24%, oil absorption of 34.58%, texture (hardness) of 232.38 g, beta carotene of orange sweet potato flour 88.34 mg/kg, beta carotene of orange sweet potato chips after being fried 40.68 mg/kg, the acceptance level panelists in terms of the ability to fracturing (6.95), the crispness (7.33), color (7.16) and flavor (6.76) with a standard score of 1-9.

Tomatoes are one of agricultural commodities that have high economic value and produced throughout the year. Tomatoes production year to year always increase and reached 950.385 ton in 2011. Number of tomatoes products is still very limited providing opportunities utilization of tomatoes into fruit leather products. Fruit leather containing 10-15% of water in a form of thin sheet that can be rolled. The quaskin pulp lity of good fruit leather is plasticy, elastic, and has a good gel form of which is determined by some components especially pectin, sugar and acid. Tomato leather which is produced with 100% tomato can not form a solid gel because pectin content in tomato is 4,63%. Therefore pectin from saba banana skin pulp is added to get a good result of it. Saba banana skin pulp has a high pectin content. Pectin content in saba banana skin pulp is 5,5%. The research design used was Randomized Group Design consisting one factor which is the proportion of tomatoes and saba banana skin pulp (100%:0%; 90%:10%; 80%:20%; 70%:30%; 60%:40%; 50%:50%). The parameters analyzed include physicochemical properties (moisture content, aw, texture (flexibility), pH, and colour) and the organoleptic properties (preference for texture, colour, and flavor). The proportion use of tomato increased moisture content, texture (gel strenght), on the other hand decreasing pH, lightness, redness, and yellowness of leather. The best proportion of tomato and banana skin pulp was at 70:30 which had pH 3.38, moisture content 11.79%, texture (gel strenght) 1.12 kg, lightness 43.8, redness 28.01, yellowness 18.9 with sensory scores of flavor, color, and texture were 5.2, 5.95, and 5 respectively with score 1-7.

Hashbrown is a product of potato that is made by shredding the potatoes, cutting into thin blocks, cut into dice, or pressed using rice potatoes then fried. The characteristic of Hash browns are soft in texture, moist and compact. In general, hash browns are made from potatoes. In this study, hash browns are made from cassava which has high carbohydrate levels, neutral aroma, light yellow colouring resembling potatoes and a savoury flavour. Hash brown product that just use cassava as a main ingredient, do not meet the characteristics of hash browns in general, which is not moist, so the addition of horseradish was necessary. Horseradish (Raphanus sativus L.) is a white tuber vegetable with 7.1% inulin. Inulin is a natural polimer formed from fructose units with a terminal glucose group. The role of inulin in hash browns is to provide moistness. Different concentration of the horseradish can give different characteristics to the taste, texture and ease of swallowing on hash brown product. The study design used is non-factorial RAK (Randomised Complete Block Design). Factors studied were concentration of horseradish consisting of 9 (nine) standard of treatments in the form of 0%(b/b); 5%(b/b);10%(b/b); 15%(b/b); 20%(b/b); 25%(b/b); 30%(b/b); 35%(b/b); 40%(b/b), with 3 replication. The parameters included physicochemical properties (moisture, fat content, absorption of oil, hardness and texture cohesiveness,) and the organoleptic properties (preference for taste, ease to swallow). The studied show that the proportion of cassava:horseradsih (70:30%) was the best, with water content 55,83%, oil absorption 32,84%, hardness 3,13 kg and cohesiveness 0,36 g, organoleptic proporties for aroma (5,51), taste (6,05), and swallowing (6,29) with standart score 1-9.

Red rice is a type of rice that is generally consumed by milling into red rice with husk still attached to the endosperm. In recent years the consumption of red rice in Indonesia begin increase and is popularized as a healthy lifestyle. One type of product that can be extended the use of red rice is red rice ice cream. Besides its high nutrition, red rice ice cream has a distinctive advantage of anthocyanin and also contains red rice flavor that characterizes the product. Ice cream has a creamy taste, easily melts in the mouth and soft texture. The texture is influenced by the presence of fat in the ice cream which helps to trap air (whipping process) that affect the amount and size of ice crystals formed. In this study the making of red rice ice cream is using red rice milk with a very small fat content in (1-2.9%), causing some differences in the physical and organoleptic properties of the ice cream. To help improve the texture of ice cream, the addition of full cream milk with a concentration of 8-13% is needed. The experimental design uses Randomized Block Design (RBD) which will be replicated five times for each treatment. Parameters that will be analysed in this study are the physicochemical parameters and organoleptic, including overrun percentage, hardness, melting rate, and organoleptic characteristics (texture, taste, flavor). Obtained data will be statistically analyzed to determine whether there are significant differences in the percentage of full cream milk powder to the parameters using ANOVA (Analysis of Variance) at Î± = 5%. If there is a significance difference, then it will be continued with DMRT (Duncanâ€™s Multiple Range Test) at Î± = 5% to determine which treatments were significantly different. The addition of full cream milk affect the overrun percentage, hardness, melting rate , and organoleptic characteristics (texture, flavor, taste) . The study result shows that overrun percentage is 16.58-22.77% and hardness is 89.07-1191.01 gram. The most preffered treatment is the addition of 13% full cream milk.
