Abstract

This community service activity was intended to assist entrepreneurs engaged in the production of alen-alen, a product made from cassava. There are some problems encountered in the production process, such as washing raw materials manually, work safety during the production practice, products that are not in accordance with standard hygiene and sanitation and packaging process that has not been designed properly. The entrepreneurs want to increase production but the equipment and processing machinery are very limited. To overcome this problem, several methods can be performed by the academics, such as facilitating them with appropriate tools that meet the needs in the field. A cassava washer unit and specific boiler tools to avoid hot steam when taking the material were offered. In addition, entrepreneurs were trained in hygiene and sanitation in alen-alen making, educated for packaging technology quality, raw material selection and the use of food coloring, formulating variations for alen-alen manufacture, as well as financial bookkeeping training. The implementation of these activities is expected to generate shorter production process time leading to further increase in the production, income and welfare of the entrepreneurs.

Abstract

The aim of this study was to determine the suitable Moringa oleifera leaf added for steamed sponge production, which was made from the mixture of wheat and banana flours. This research was conducted. This research was conducted by using completely randomized design with 2-factors, namely percentage of moringa leaf flour (K): (0,0% ; 1,0% ; 2,0%) and comparison of mixture wheat flour and banana flour (P): (100%:0% ; 75%:25% ; 50%:50% ; 25%:75%). The results showed that the addition of more moringa leaf flour increased the ash, protein and crude fiber contents in the composite flours. The increment might be related to higher ash, protein and fiber contents in moringa leaf flour than that of in both wheat flour and banana flour. In addition, higher banana flour substitution raised the moisture and ash contents. Meanwhile, the specific volume of cake decreased because banana flour does not have gluten. Based on the protein content and organoleptic values, the addition of 2% moringa leaf flour and the ratio of wheat flour to banana flour (75%:25%) produced the best quality of steamed sponge cake.

Abstract

The purpose of this research was to determine the effect of stabilizer types and percentages on the quality of instant garfish condiment. The research used a group randomized design factorial with two factors, i.e.: types of stabilizer (CMC; Arabic gum; gelatin) and percentage of stabilizer (0.0%; 0.5%; 1%; 1.5%). The results showed that stabilizer types had a highly significant effect on water absorption index, water solubility index, vitamin C, and color index. Moreover, the stabilizer had no significant effect on organoleptic aroma and taste. In the meantime, stabilizer percentages had a highly significant effect on water absorption index, water solubility index, vitamin C, color index, and organoleptic aroma. However, the stabilizer percentages gave no significant effect on organoleptic taste. Interaction between the two factors had a highly significant effect on water absorption index and vitamin C and had a significant effect on color index. Furthermore, the interaction had no significant effect on water solubility index, organoleptic aroma and taste. The best treatment product was resulted from the use of 1.5% CMC as stabilizer.

Abstract

This research was conducted to determine the effect of the percentage of non-dairy cream and Moringa leaves filtrate on the characteristics of peanut ice cream. This research used a Completely Randomized Design (RAL) method with two factors i.e the percentage of non-dairy cream (10, 20%, 30%, and 40%) and the percentage of Moringa leaves filtrate (0%, 10%, 20%, and 30%) with three repetitions. The results showed that the percentage of non-dairy cream had a highly significant effect on fat and water content, total dissolved solids, overrun, melting time, and hedonic value of texture. The percentage of Moringa leaves filtrate had a highly significant effect on protein, fat, and water content vitamin C content, total dissolved solids, overrun, melting time, and hedonic value of taste. Interaction between the percentage of non-dairy cream and moringa leaves filtrate had a highly significant effect on fat content, total soluble solids, and overrun. Antioxidant analysis was conducted on the best treatment with a percentage of 40% non-dairy cream and 30% Moringa leaves filtrate with IC50 of 146.6368 ppm.

Abstract

This study aimed to determine the Effect of using stevia leaves as a natural sweetener on dried sweets of Padang Sidempuan's snake fruit. The method used in this study was the factorial Complete Randomized Design (CRD) method with two factors, namely the amount of stevia leaf powder (0,20%: 0,25%; 0,30%; 0,35%) and drying time (4, 6, 8 and 10 hours). The tests carried out were moisture content, ash content, total sugar, total dissolved solids, total microbes, acidity (pH), and organoleptic tests of colour, flavour, taste, and texture. This study's results showed a highly significant effect exerted by the amount of stevia leaf powder on moisture content, ash content, total dissolved solids, total sugar, total microbes, acidity (pH), and an organoleptic test of colour, flavour, and taste. Drying time significantly affected moisture content, ash content, total sugar, total microbes, total dissolved solids, and texture organoleptic test. The interaction between the amount of stevia leaf powder and the drying time had a highly significant effect on moisture content and a significantly different effect on total microbes and organoleptic colour. The amount of stevia leaf powder is 0,35%, and the drying time of 8 hours results in the best treatment on dried sweets of Padang Sidempuan's snake fruit.

Abstract

This research aimed to determine the effect of adding dragon fruit peel and red ginger extract on the characteristics of jelly candy made from Aloe vera. The study used a randomized  block design (RBD) with two factors: the ratio of Aloe vera and dragon fruit peel (100:0, 90:10, 80:20, and 70:30) and red ginger extract (0%, 5%, and10 %). The parameters analyzed were moisture content, ash content, color value (⁰Hue), reducing sugar content, pH, crude fiber, anthocyanin value, antioxidant IC50, total phenol, as well as the hedonic values of color, aroma, taste, texture, and general acceptance. The results showed that the ratio of Aloe vera and dragon fruit peel significantly affected the ash content, color value (oHue), reducing sugar content, crude fiber, anthocyanin value, antioxidant IC50, total phenol, hedonic of color, and general acceptance. The red ginger extracts significantly affected ash content, color value (oHue), reducing sugar content, antioxidant IC50, total phenol, hedonic aroma, and taste. The interaction between the two factors significantly affected the color value (oHue) and total phenol. The formulation with a ratio of aloe vera:dragon fruit peel (70:30) and  10% red ginger extract yielded the best jelly candy.
