<p class="Abstrak"><span lang="EN-GB">By processing sorghum grains into flour, the use of sorghum grains to support food diversification can be made more varied. The research objective was to determine the physical and chemical properties of sorghum muffins and changes of physical properties of sorghum muffins during storage. The research uses a completely randomized design with two factor, grain soaking duration (hours) and ratio of concentration of whole sorghum flours with gluten flour (%) and consists of nine treatments combination. The result shows that treatment has a significant effect on the power expansion, degree of brightness, fat, and preference for organoleptic properties. The best treatment was 24-hours of soaking, 25% whole sorghum flour, 75% gluten flour that produces expanded power at 138,83%, degree of brightness (L) at 67.03, redness (a) at +4.33, yellowness (b) at +27.37, water content of 12.59%, protein content of 6.95%, fat content of 2.46%, score of color at 3.20, texture score at 3.13, aroma score at 3.16, taste score at 3.24, and for overall acceptance at 3.53 (like). Changes of physical properties of sorghum muffins during storage for 3 days can be explained with the linear equation. For all parameter (weight loss, volume loss, brightness loss), the value of constant a in the equation of sorghum muffin was lower than control muffin that indicated quality loss of sorghum muffins is higher than control muffin. Increasing the concentration of sorghum flour resulted a decrease in the quality of the muffins. The soaking treatment of the seeds in making sorghum flour can maintain the quality of the muffin.</span></p>

               Natural or local yeasts are microorganisms from natural ingredients obtained from fermentation without the need for artificial additives. The objectives of the present study were 1.) to evaluate the physical quality of potato doughnuts produced from the local yeast derived from residue of red fermented palm sap, 2) to obtain the best treatment from the use of local yeast in making doughnuts. In the fermentation process, yeast converts sugar and carbohydrates in the dough into carbon dioxide gas (CO2) and alcohol. Doughnuts are made from wheat flour, but the addition of potato paste can improve the texture so that it is softer and tender due to the interaction between gelatinized starch and gluten but can reduce its swelling power.             The experiment was designed using a completely randomized design (CRD) with three treatments and five replications to produce 15 experimental units. The treatments were a) Control (commercial yeast); b) Wheat flour: potato paste: local yeast; 2:1:1; c) Wheat flour: potato paste: local yeast; 2:1:2 and d) Wheat flour: potato paste: local yeast; 2:1:3. The results showed that the best treatment formula was obtained in the treatment B (wheat flour: potato paste: local yeast; 2:1:1) with 20,6% moisture content,  2,09% protein content and 3,644 color value (very like), 3,800 taste value (very like) and texture/tenderness with a value of 1032,500.

Organical material such as animal dung, husk ash, bran, and sawdust is often used  in bocation production. In this study, the paper waste of printing company at Syiah Kuala University was enriched in the raw material of bocation production. This study was aimed to determine the proportion of paper waste that can be added and the duration of fermentation process in order to produce a good bocation. The method used was a factorial Completely Randomized Design (CRD) which consisting of 2 factors. The first factor was the proportion of paper waste (K) with  4 levels: K1 = 15%, K2 = 25%, K3 = 35%, and K4 = 45%. The second factor was the fermentation duration (L) with 3 levels: L1 = 0 day, L2 = 10 days, and L3 = 15 days. Each treatment was repeated twice so that there were 24 experimental units. The analysis included: water content, total microorganisms, temperature, pH, C element, N element, C/N ratio, organoleptic (texture, aroma, color) and plant growth test. The result showed that additional paper waste with a proportion of up to 35% generally has a positive effect on the quality of the location in terms of water content, pH, nitrogen, texture, aroma, color, and plant growth. The longer the fermentation took place (up to 15 days) the better was the quality of the bocation produced, especially regarding C element, N element, C/N ratio, texture, aroma, color and plant growth. There were 3 interactions with the best plant height namely K3L3 (112.5cm), K3L2 (104 cm) and K2L3 (104 cm). The K3L3 bocation (35% paper waste proportion, 15 days fermentation) was better than the other two interactions in term of highest water content, N, and color value, and the lowest C/N ratio.
