Abstract

The objective of this research was to find the optimum substitution of wheat flour with sweet potato starch flour (Ipomoea batatas L.) in making noodle. The research was arranged in Completely Randomized Design with three replications. The treatments were PO (100% wheat flour); P1 (10% sweet potato starch flour and 90% wheat flour); P2 (20% sweet potato starch flour and 80% wheat flour); P3 (30% sweet potato starch flour and 70% wheat flour); and P4 (40% sweet potato starch flour and 60% wheat flour). The result indicated that treatments did not significantly influence water content, ash content, proteinscontent, starch content, and elasticity but significantly influenced flavor and taste of fried noodle. All the treatments met the SII for dried noodle (SII 0178-90). The best treatment was P2 (20% sweet potato starch flour and 80% wheat flour) for all parameters.

Abstract

The demand of Indonesia for wheat flour is predicted to increase by at least 6% every year. Meanwhile,Indonesia especially Riau Province has many kinds of food recourse viz. sago starch. The objective of thisstudy was to find out the best formulation in production of sweet bread made from wheat flour substitutedwith sago flour. Experimental study was conducted in Completely Randomized Design with six treatmentsand each treatment was done in three replications. Parameters observed were the contents of moisture, ash,and starch as well as leavening power, self life and organoleptic assessment of sweet bread. The dataobtained were analyzed by ANOVA and was continued with DNMRT test at 5% level. The organoleptic datawere analyzed by Friedman Test and data of gelatinous filament, flavor and rancidity were presented bydescriptive analysis. Results showed that substitution of wheat flour with sago starch significantly influencedmoisture and starch contents, leavening power and the organoleptic properties of sweet bread. However,substitution of sago starch did not affect ash content of sweet bread. In general, substitution up to 50% ofsago starch had met the Indonesian quality standard of sweet bread (SNI 01-3840-1995) except for lowleavening power. In addition, the self life of sweet bread in the treatment TM5 (wheat flour 50% and 50%sago starch) was similar to that of commercial sweet bread.Key words: sweet bread, sago starch, quality, self life

Abstract

Seed of picung (Pangium edule Reinw) contains 70 % kernel (weight) and 40 % husk (weight). Itsnucleus’s seeds contain 21-27 % oils that can be extracted. More than its 70 % component is an oil cake.The huge amount of oil cake can be used as a solid fuel such as Biomass Briket (Baiobriket). Biobriket hasweight 23,046 gram,long 3,469 cm, wide 2,804 cm and high 2,277 cm. Biobriket picung is produced bymanual process inlet dry materials that is pushed and pressed by hydroulic press. The pressing processproduces solid materials that will be piece into specific size. Picung oil cakes have a weakness as a solidfuel. It has no high heating value and its physic characteristic that has low binder. To increasing heatingvalue, glycerol is added. Because glycerol has a heating value equal to 1353 kcal/ kg. Glycerol can beused as an alternative heating resource. Binding problems can be solved by adding tapioca. Optimumadding of tapioca is not more than 5%. The final step of this research is found the comparison of qualitybetween optimal biobriket picung oil cake. This research used central composit design. The first factorwas quantity of glycerol (X1) and the second factor was quantity of tapioca (X2). Picung oil cake usedwas 200 gram. First factor’s range was between 1 – 5,5 % weight of oil seed or at 1,76-9,69 ml (densityglycerol was 1,13 g/ml). The seconds factor range was 1 – 5 % weight of oil cake or at 2-10 gram.Optimation response used was heating value (Y). Analysis with response surface method shows thataddition of glycerol had a positive influence to the heating value of biobriket with desirability 94 %. Theoptimum value for heating calor biobriket was 6243,62 kcal/kg.

Abstract

Edible film is a biodegradable packaging that composed from organic compound. Edible film can becontaminated by pathogen bacteria. Kaffir lime leaves essential oil has able to inhibit bacteria growth. Theaim of the study was to determine the best concentration of kaffir lime leaves essential oil as antibacteria ontapioca edible film. The experiment research used a completely randomized design, which consist of fivetreatments within three replications. The treatmens were concentration of essential oil i.e A1 (0% v/v), A2(0,5% v/v), A3 (1% v/v), A4 (1,5% v/v) and A5 (2% v/v). Data were obtained using analysis of variance andcontinued by Duncan New Multiple Range Test at level 5%. The result showed that the treatments significantlyaffected on water content, solubility, resistance of water, and water vapour transmission rate. Edible film withadditional of essential oil inhibit the growth of Staphylococcus aureus FNCC-19 and Escherichia coliFNCC-15. The best treatment was A5 (2% of essential oil) with thickness 0,156 mm, water content 22,87%,solubility 30,82%, resistance of water 161,29%, water vapour transmission rate 0,291 g/m2/h, diameterinhibition 20.16 mm of Staphylococcus aureus FNCC-19, and 30.45 mm of Escherichia coli FNCC-15.

Abstract

Jelly candy is one from of diversification of products aloe vera and seaweed. This study aims to get the right ratiobetween aloe vera and seaweed to produce jelly candies with good quality. Parameters observed in this studymoisture content, ash content, pH, reducing sugar content, crude fiber content and organoleptic testing the level ofpreference panelist on candy jelly with aloe vera and the ratio of seaweed. The study was conducted using acompletely randomized design with 3 (three) replications consisting of 5 (five) treatments are:LR1 (aloe vera 90% :10% seaweed), LR2 (aloe vera 80% : 20% seaweed), LR3 (aloe vera 70% : 30% seaweed), LR4 (aloe vera 60% :40% seaweed), and LR5 (aloe vera 50% : 50% seaweed). The result of analysis showed that the ratio of aloe veraand seaweed significantly effect on moisture content, ash content, reducing sugar content, and crude fiber contentand not significantly effecton pH and the overall ratio of aloe vera and seaweed preferred by the panelists. Theratio of aloe vera and seaweed in the treatment LR4 (aloe vera 60%:40% seaweed) is best treated with a moisturecontent of 16.44%, ash content 0.38%, pH 3.36, reducing sugar content 22.62%, crude fiber content of 1.44% andpreferred by the panelists in organoleptic testing.Key words: Aloe vera, seaweed, jelly candy
