This study aimed to test the physical and chemical quality characteristics of corn tortillas with substitute purple sweet potato flour. This study used a completely randomized design (CRD) and LSD test if there was a significant effect. The tests carried out included organoleptic tests, air content analysis, ash content analysis, color analysis and texture analysis. The results showed that the best formulation of tortillas chips was a P4 treatment with the addition of 75% purple sweet potato flour: 25% corn, with a texture value of 4.267, taste 4.75 and aroma 4.56 and for the best color treatment found in the addition of P3 had a value of 4.31. The best treatment in the chemical analysis is the P4 treatment had a color value of -10.93, moisture content of 8.94 and ash content of 2.57. For texture analysis test the highest treatment was P2 treatment with the addition of 25% purple sweet potato flour: 75% corn with a value of 1139.15.

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.

Purple sweet potato is one type of tuber that is rich in carbohydrates in the form of starch and fiber. It also contains purple anthocyanin pigments. In this research, purple sweet potato was processed into flour and starch. Starch processing solid waste can be utilized by processing it into fiber flour. Purple sweet potato flour and fiber were then used as the basis for making biscuits at a ratio of 75: 25 and compared to biscuits made from 100% purple sweet potato flour and wheat flour. The resulting biscuits were then analyzed for their chemical characteristics. The results showed that the ratio of flour gave a very significantly different effect on the value of water content, total dietary fiber content, insoluble dietary fiber content and % nutritional adequacy rate of food fiber, and had no significant effect on the value of ash content, protein content, fat content, content carbohydrates, total flavonoids, insoluble dietary fiber content, calorie intake and fulfillment of daily energy adequacy.

Penelitian ini bertujuan untuk mengkaji proses pembuatan tepung ubi jalar ungu dengan variasi lama perendaman dalam larutan kalsium hidroksida. Tahapan proses pembuatan tepung ubi jalar adalah pengupasan, pemotongan membentuk chips dengan ketebalan 1 cm, perendamandalam larutan kalsium hidroksida Ca(OH)2, blanching pada suhu 85oC selama 5 menit, pengeringan bertahap dengan penjemuranselama 2 hari dan pengeringan oven selama 6 jam pada suhu 60oC sampai kadar air 10%, penggilingan dan pengayakan. Perendaman dalam larutan Ca(OH)2 konsentrasi 1.000 ppm dilakukan dengan  variasi lama perendaman 0, 15, 30 dan 60 menit. Parameter yang diamati meliputi rendemen, susut bobot, kadar air, kandungan pati, vitamin C, derajat keasaman, dan warna. Hasil penelitian menunjukkan bahwa rendemen yang dihasilkan pada berbagai variasi lama perendaman dalam larutan Ca(OH)2adalah 10,63%-10,79%, sedangkan kadar air tepung ubi jalar ungu diperoleh pada kisaran 8,4-10,27%. Susut bobot tertinggi diperoleh pada proses pengeringan matahari yaitu mencapai ±36,36%, sedangkan susut bobot terendah terjadi pada proses pengayakan yaitu ±3,13%. Kandungan pati tepung ubi jalar ungu berada pada kisaran 74,47-84,83%. Vitamin Ctepung ubi jalar ungu terendah diperoleh pada perendaman 60 menit sebesar 4,40 mg/100g, sedangkanvitamin C tepung ubi jalar ungu tertinggi diperoleh pada perendaman 0 menit yaitu 17,60 mg/100g. Secara umum dapat disimpulkan bahwa terjadi penurunan vitamin C selama proses penepungan. Derajat keasaman tepung ubi jalar ungu diperoleh pada kisaran 4,96-5,27. Berdasarkan analisis warna diperoleh tepung ubi jalar ungu dengan warna ungu ke kehitaman (perendaman 0 menit), ungu pucat (perendaman 15 menit), ungu pekat (perendaman 30 menit), dan ungu keabu-abuan (perendaman 60 menit).The study aimed to evaluate the purple sweet potato flour processing under variations of soaking time in calcium hydroxide solution. The steps of flour processing were pilling, cutting with a thikcness of 1cm, soaking in calcium hidroxide solution, blanching at a temperature of 85 oC for 5 minutes, drying at two stages i.e sun drying for two day and oven drying for 6 hour at  60oC until 10% moisture content miling and sieving. Soaking in calcium hidroxide  concentration of 1,000 ppm was done by variation soaking time of 0, 15, 30 and 60 minutes. The parameters observed were yield, weight loss, moisture, starch content, vitamin C, acidity, and color. The results showed that the yield generated due to variations of soaking time in calsium hidroxide solution was 10.63-10.79%, while the moisture content of the purple sweet potato flour was in the range of 8.4-10.27%. The highest weight loss was obtained in the sun drying process (±36.36%), while the lowest weight loss was occured in the sieving process (± 3.13%). The starch content of purple sweet potato flour was in the range of 74.47-84.83%. The lowest vitamin C of purple sweet potato flour was obtained after 60 minutes soaking (4.40 mg/100g), while the highest vitamin C of purple sweet potato flour was obtained without soaking (17.60 mg/100g). In general it can be concluded that vitamin C had been declined during the flour processing. The acidity of purple sweet potato flour was in range of 4.96 to 5.27. The  color analysis by using L*a*b method showed that there was differences in color due to the variation of soaking time.
