Cassava flour substitution in the dough preparation often result in dough that is not properly hydrated. The purpose of the research was to determine the proper water volume in making dough from wheat flour and cassava flour mixtures. The research was conducted by analyzing amylograph characteristic and water absorption capacity of wheat flour and cassava flour mixtures. The water absorption was used as a reference to determine the volume of water in the dough preparation of mixed flours. Then, the elongation properties of the doughs were measured. Amylograph data indicated that wheat flour displayed a higher temperatur stability than cassava flour. The more portion of cassava flour, the lower its thermal stability. The water absortion of cassava flour was higher than wheat flour. The increasing of water absorbtion, in line with the increasing of cassava flour portion, which gave a linear trend, R= 0.972. Based on the technique of proportional to water absorption in determine the water volume, the biggest tensile strength of dough was revealed by wheat flour:cassava flour 100:0 and 90:10. However, the highest strain displayed by dough of wheat flour:cassava flour 100:0.ABSTRAKSubstitusi tepung singkong dalam pembuatan adonan roti seringkali menghasilkan adonan yang tidak terhidrasi dengan baik. Tujuan dari penelitian ini adalah untuk menentukan volume air yang tepat dalam pembuatan adonan dari campuran tepung terigu dan tepung singkong. Penelitian dilakukan dengan menganalisis sifat amilografi dan daya serap air dari campuran tepung terigu dan tepung singkong. Data daya serap air dijadikan acuan dalam penentuan volume air pada pembuatan adonan dari campuran tepung terigu dan tepung singkong. Kemudian dilakukan analisis elongasi adonan. Hasil amilografi menunjukkan bahwa tepung terigu lebih stabil terhadap panas dibanding tepung singkong. Makin besar porsi penambahan tepung singkong, semakin kecil stabilitas panasnya. Tepung singkong menunjukkan daya serap air yang lebih tinggi dibanding tepung terigu. Peningkatan daya serap air dari campuran tepung, seiring dengan peningkatan porsi tepung singkong, yang memberikan kecenderungan linear, dengan nilai R = 0,972. Berdasarkan teknik proporsional dengan daya serap air dalam menentukan volume air, tensile strength terbesar diberikan oleh adonan dari tepung terigu:tepung singkong 100:0 dan 90:10. Sedangkan strain tertinggi ditunjukkan oleh adonan campuran tepung terigu:tepung singkong 100:0.

This study was aimed to find out the physical characteristics and sensory acceptance of bread made from different variations of wheat and cassava composite flour ratio, and the dough’s mixing duration. The research was conducted experimentally with 4 ratio variations of wheat and cassava flours, namely 100:0, 90:10, 80:20 and 70:30, and 3 variations of dough mixing duration, namely 10 minutes, 15 minutes and 20 minutes. The analyzed parameters for dough were the development and the elongation, and for bread were the development, hardness, elasticity, and acceptance. The results showed that the higher the cassava flour proportion, the lower the level of dough development. The dough development was affected by mixing duration, but there was no increasing tendency of the cassava flour. The treatment of 100:0 (15 minutes), which was not significantly different from 90:10 (15 minutes), indicated the highest dough development. The higher the cassava flour proportion, the lower the dough’s tensile strength and the strain, while the mixing duration showed the influence on the dough’s tensile strength and strain. Both indicators gave the same highest point, it was the treatment of 100:0 (15 minutes). The bigger the cassava flour proportion, the lower the bread development. The highest bread development was given by 100:0 treatment, but there was no effect of mixing time on this treatment. The bigger the cassava flour proportion, the higher the bread’s hardness, while for the bread’s elasticity, it showed the opposite, the higher cassava flour, the lower the bread’s elasticity. The two bread texture indicators were influenced by the mixing time but did not provide a steady tendency toward the increasing proportion of cassava flour. The highest bread hardness was indicated by the 70:30 treatment, while the biggest bread elasticity was with the treatment of 100:0. The highest acceptance of bread was revealed by 100:0 treatment, which was not significantly different from 90:10 treatment.

The main cause of the high prevalence of iron deficiency anemia of children in Indonesia is the low intake of iron. Green spinach flour as a source of iron can be used as a substitution material in the manufacture of biscuits. The purpose of the study was to evaluate the effect of green spinach flour substitution on iron, hardness and acceptance levels of biscuits from composite cassava flour and wheat flour. The research was conducted by substituting the green spinach flour with various levels of 0%, 2.5%, 5% and 7.5%. The biscuits were then tested for the iron using Atomic Absorption Spectrophotometer (AAS), hardness using texture analyzer and acceptability. The results indicated that there was a substitution effect of green spinach flour to iron and acceptability of biscuits, whereas, there was no effect on the hardness. The higher the substitution of green spinach flour, the higher the iron level of the biscuit. The highest iron level was displayed by biscuit with the substitution of 7.5%, which was 89.82mg/kg. The hardness of biscuits was not affected by the substitution of green spinach flour. The range of biscuit hardness levels was between 2592.16g - 3985.83g. Biscuit with 5% substitution of green spinach flour gave the highest acceptability. The iron requirement of Indonesian school-age children (7-9 years) can be fulfilled by consuming biscuits (5% green spinach flour) as much as 14 grams or equivalent to 3 pieces of biscuit for a day.
