Cookies are crispy textured cakes. The main ingredient used to make cookies is wheat flour. Substitution of flour with purple sweet potato is done because purple sweet potato has content such as wheat flour. Purple yam flour contains amylose of 24.79% and amylopectin of 49.78%.This research was conducted to analyze on fat level and water content in cookies. The study design was a Randomized Block Design. The treatment level was divided into 4 groups with the proportion of purple sweet potato flour:  F0 (0%: 0%), F1 (55%: 20%), F2 (45%: 30%), and F3(35%: 40 %). Fat content analysis used was the soxhlet method. There was a significant effect (ρ = 0,000) on the amount of fat content in cookies. The highest fat content found in F3 was 38.85%.Water content analysis used was the Thermogravimetric method. Statistical analysis of water content using friedmen with a reliability level of 95%. There was a significant effect (ρ = 0,000) on the amount of water content in cookies. The lowest water content was in F3 of 38.85%. The higher the addition of peanut flour, the lower the water content of cookies. Keywords: Cookies, Purple Sweet Potatoes, Ground Peanuts, Fat Levels, Water Content

Sweet potatoes in general, including vines that have tubers as a producer of carbohydrates, but the quantity and quality is very different from other tubers. Instant noodles are generally made from raw materials of wheat flour, but with the abundance of sweet potatoes found, noodles are made using purple sweet potato flour instead of wheat flour. The purpose of this study was to determine the effect of purple sweet potato flour substitution at various concentrations on the physical, chemical and sensory tests of instant noodles. The study was conducted at the Agroindustry Laboratory, Faculty of Agriculture, University of Tadulako, from June to December 2019. The experiment was arranged using a Completely Randomized Design (CRD) with 1 factor, namely the substitution of instant noodles purple sweet potato flour at a concentration of 0.5,10,15, 20.25 and 30%. The treatment was repeated 3 times so that 21 units of the experiment were obtained. For sensory testing using a Randomized Block Design (RBD) with a panelist of 30 people. Observation parameters consisted loss of solids due to cooking (KPAP), water absorption, water content, ash content and sensory tests. The results of the study of purple sweet potato flour substitution at various concentrations gave the best effect on the concentration of 30% on instant noodles produced based on physical, chemical and sensory properties. With the highest loss of solids due to cooking ( KPAP). The absorption of instant noodles decreases with increasing concentration of purple sweet potato flour. Instant noodle water content tends to be constant in every treatment. Ashes of instant noodles increase with increasing concentration of purple sweet potato flour and the sensory properties of color, texture, aroma, and taste of instant noodles produced increase with increasing concentration of purple sweet potato flour with hedonic scale categories like. Noodles substituted with purple sweet potato flour can be consumed as instant noodles such as those circulating in the market.

This study aims to determine the effect of making churros from rice flour and sweet potato flour. This study uses a completely randomized factorial pattern with 2 factors, namely the comparison of the composition of rice flour and sweet potato flour. While the second factor is the type of flour used, namely purple sweet potato flour and Cilembu sweet potato flour. The resulting churros will be observed for quality including water content, fat content, and organoleptic test (preference and descriptive). The results of this study indicate that panelists prefer churros made of 30 TB: 70 TU. The lowest value of fat content is 30TB: 70TC which is 16,715%. Water content value of 30TB: 70TU with a value of 19.13%.

The objective of the study was to determine the concentation ratio between purple sweet potato flour and wheat flour in order to produce purple sweet potato cookies having particular nutritional content and preffered by consumers. A completely randomized experimental design was applied in this study. One experimental factor which was ratio of purple sweet potato flur and wheat flour consisting five level of treatments, was as signed i,e 100%: 0%, 80:20%, 60%:40%, and 20%: 80% respectively. Variables measured were chemical composition (protein, fat, moisture, anthocyanin content) and sensory properties (colour, taste, texture, overall likeness). Results showed that most variables were influenced by the ratio of sweet potato flour and wheat flour, excluding moisture content. The ratio of 80% sweet potato flour : 20% wheat flour resulted in cookies with good characteristics and mostly preffered by parelists. Anthocyamin content of this particular cookies (80%: 20%) was similar to that of sweet potato flour.  Keywords: cookies, purple sweet potato flour, wheat flour   ABSTRAK  Penelitian ini bertujuan untuk menentukan konsentrasi tepung ubi jalar ungu dan tepung terigu yang tepat untuk menghasilkan kue kering ubi jalar ungu dengan kandungan gizi tertentu dan disukai.

The purpose of this study was to obtain maltodextrin with the appropriate concentration of purple sweet potato anthocyanin extract to produce the natural dye powder preparations with the best physical and chemical characteristics. The research method used is Experimental Method (Experimental Method) by using Group Random Design (GRD). The experiment consisted of three treatments and each was repeated four times, with the treatment obtained in cassava purple with a concentration of 35.4 mg / 100gr anthocyanin extract.  The  next  stage  was  to  determine  the  best  concentration  of  maltodextrin Consisting of four treatments and each repeated three times. The anthocyanin pigment powder of purple sweet potato with various treatments of maltodextrin concentration addition gave a significant effect on the soluble time, and yield, but did not gave a significant effect on total of anthocyanin, hygroscopicity and solubility. The treatment 10% of maltodextrin concentration addition resulted in best characteristic with total anthocyanin of 48.43 mg / L, color intensity L * (brightness) of 37.86, a * (redness) of 43.66, b * (yellow) of 21.68, water content of 5.56%, hygroscopicity of 11.62%, solubility of  97.13%, soluble time of 159 seconds, pH value of 3.04, and yield of 31.38%. The resulting anthocyanin powder shows that the anthocyanin pigment powder of purple sweet potato with the maltodextrin concentration addition has the potential to serve as a natural dye powder for food and beverages.
