Dehydrated uncooked potato (Irish and sweet) flour was blended by weight with commercial wheat flour at 0 to 10% levels of substitution to make bread. Comparative study of the microbial and nutritional qualities of the bread was undertaken. The total aerobic bacterial counts ranged from 3.0 × 105 cfu/g to 1.09 × 106 cfu/g while the fungal counts ranged from 8.0 × 101 cfu/g to 1.20 × 103 cfu/g of the sample. Coliforms were not detected in the bread. Bacteria isolated were species ofBacillus,Staphylococcus, andMicrococcuswhile fungi isolates were species ofAspergillus,Penicillium, Rhizopus, andMucor. The mean sensory scores (color, aroma, taste, texture, and general acceptability) were evaluated. The color of the bread baked from WF/IPF2(wheat/Irish potato flour, 95 : 5%) blend was preferred to WF (wheat flour, 100%) while WF/SPF1(wheat/sweet potato flour, 100%) and WF/IPF1(wheat/Irish potato flour, 90 : 10%) aroma were preferred to WF. However, the bread baked from WF, WF/IPF2(wheat flour/Irish potato flour, 95 : 5%), and WF/SPF2(wheat/sweet potato flour, 95 : 5%) was more acceptable than other blends. The use of hydrated potato flour in bread making is advantageous due to increased nutritional value, higher bread yield, and reduced rate of staling.

ABSTRACT           The purpose of this research was to determine the effect of the ratio of tapioca flour, glutinous flour and purple sweet potato flour to the physicochemical properties of dodol with chemical quality (moisture content, total anthocyanin, and reduction sugar) and physical quality of the color (L value and oHue value). This study used Randomized Block Design (RBD) consisting of 6 treatments T1= Tapioca Flour 80%: Glutinous Flour 10%: Purple Sweet Potato Flour 10%, T2= Tapioca Flour 70%: Glutinous Flour 15%: Purple Sweet Potato Flour 15%, T3= Tapioca Flour 60%: Glutinous Flour 20%: Purple Sweet Potato Flour 20%, T4=Tapioca Flour 50%: Glutinous Flour 25%: Purple Sweet Potato Flour 25%, T5= Tapioca Flour 40%: Glutinous Flour 30%: Purple Sweet Potato Flour 30%, T6= Tapioca Flour 30%: Glutinous Flour 35%: Purple Sweet Potato Flour  35% with 3 times repetitions. The data of the research were analyzed using the diversity analysis at 5% level using Co-stat software and tested continued using the test of Honest Real Difference (HRD) if there was real difference. The results showed that the ratio of tapioca flour, glutinous flour and purple sweet potato flour gave a significantly different effect on chemical quality (moisture content, total anthocyanin, and reduction sugar), and physical quality of the color (oHue value) but gave no significant effect on physical quality of the color (L value). The result showed that the ratio of tapioca flour 30%: glutinous flour 35%: purple sweet potato flour  35% was the best treatment with moisture contect of 24.21%, total anthocyanin 8.48 mg/100g, reducing sugar 7.83%, L value of 23.85 and oHue value 360.14   Keywords: dodol, glutinous flour, tapioca flour, purple sweet potato flour   ABSTRAK Tujuan dari penelitian ini adalah untuk mengetahui pengaruh rasio tepung tapioka, tepung ketan dan tepung ubi jalar ungu terhadap sifat fisikokimia dodol dengan kualitas kimia (kadar air, total antosianin, dan kadar gula reduksi) dan mutu fisik warna (nilai L dan nilai oHue).

The study was carried out in order to find out the effect of substitution of wheat flour with sweet potato flour of two local varieties (Local Sada and Local Lal) on the quality of bread. This study was also concerned with the analysis of proximate compositions of sweet potato and results showed that, fresh local sada and local lal sweet potato varieties contained moisture 70.10 and 66.78%; ash 4.46 and 4.21%; fat 0.71 and 0.74%; protein 1.75 and 1.63%; carbohydrate 22.98 and 26.64%; vitamin-C 8.86 and 9.49 mg/100g respectively. The compositions of sweet potato flour were also analyzed and showed that local sada and local lal sweet potato flour contained moisture 5.25 and 5.32%; ash 4.12 and 4.17%; fat 0.75 and 0.81%; protein 9.80 and 9.21%; carbohydrate 80.08 and 80.49%; vitamin-C 2.45 and 2.31 mg/100g respectively. This analysis showed that the sweet potato flour is quite rich in protein content. The breads containing of sweet potato flour were prepared using standard formulation with 5, 10 or 15% substitution of wheat flour by sweet potato flour and evaluated their acceptability by a number of panelists. The result obtained showed that the color, taste, texture, flavor and overall acceptability of the breads containing sweet potato flour were equally acceptable with control bread. Statistical analysis showed that the overall acceptability of bread with sweet potato flour was equally acceptable as the control bread and bread with 10% substitution level (local lal) was moderately acceptable and other products (including 15% substitution) were ranked as like slightly.

Background: The development of ice cream products by adding certain ingredients such as fiber can improve the quality of the product as a healthy food. Research pur¬poses: This study aims to analyze the effect of the water-soluble polysaccharide substi¬tution of gembili tubers with purple sweet potato flour on nutritional quality, physico-chemical properties, and organoleptic quality of ice cream. Method: This study used a completely randomized design (CRD), consists of four levels, namely control (P0) and water-soluble polysaccharide substitution treatment of gembili tubers with purple sweet potato flour; P1, P2, P3 with three replications each. Results and Discussion: The results of the research on ice cream substitution of water-soluble polysaccharide of gembili tubers with purple sweet potato flour showed a significant effect (P <0.05) on ash, protein, and carbohydrate content, and there was no significant effect on mois¬ture content and energy value. Caused increase in the volume of ice cream products at all levels of substitution treatment (P0, P1, P2, and P3). P0 was the ice cream prod¬uct with the highest increase (2,057 times, and then P3 (1,933 times). In the treatment of ice cream, water-soluble polysaccharide substitution of gembili tubers with purple sweet potato flour, there was a change in the ash, protein, fat, carbohydrate content. energy and increased fiber content. Conclusion: The best level of treatment based on the effectiveness index is P3.

Research-based community partnership program activities involve two partners, namely the Murti Lestari Farmer Group and Agrina Creation UKM in Helvetia Village, XI Gang Sawit Hamlet, Labuhan Deli District Deli Serdang Regency. This dedication activity is the application of the results of research that had been carried out two years earlier which was USU's Talent Grants in 2017 and 2018. The problem faced was the lack of understanding of oyster mushroom baglog waste management techniques that have the potential to pollute the environment, on the other hand the farmer group Murti Lestari also experienced difficulties in increasing the quantity and quality of sweet potato production which is also widely cultivated in this village. The low interest of farmers is also encouraged because of the low price of sweet potato products and a relatively limited shelf life. The method implemented for training and discussion, accompanied by the practice of making compost from mushroom baglog waste, the practice of preparing planting material in the form of local sweet potato clones with high beta carotene content, compost application in sweet potato cultivation, maintenance to harvesting and post-harvest process using processing equipment into sweet potato flour rich in beta carotene and various other processed food products. Activities that have been carried out are training on composting of baglog mushroom waste using compost counting machines and bioactivators introduced in this activity so that the composting process goes faster, training on technical culture of orange sweet potato cultivation by applying mushroom baglog compost, training on mushroom making mushrooms and composting Oyster mushroom cultivation using shelves made of mild steel and fogging using a sprayer. Production and quality of yields of sweet potatoes that were given compost baglog oyster mushroom waste increased compared without the provision of compost. The next crop is processed into sweet potato flour with high beta carotene content and various food products using an introduced machine, which is a sweet potato slicing machine, flour machine, macaroni making machine and equipment for making sweet potato flour based food processing products.
