    The purpose of this research was to acquire best cookies of substitution purple sweet potato flour, tempe flour and small shrimp flour in terms of organoleptic and nutritional content. This research used Complete Randomized Design (CRD) with four treatments and four replications. The treatments were UB1 (purple sweet potato flour 71%, tempe flour 29%), UB2 (purple sweet potato flour 67%, tempe flour 33%), UB3 (purple sweet potato flour 63%, tempe flour 37%), UB4 (purple sweet potato flour 59%, tempe flour 41%). The result showed that make of cookies substitution purple sweet potato flour with tempe flour that different gave the significant effect to the ash content, protein content and taste, but non significant effect to the moisture content, colour, texture, aroma, overall and organoleptic assessment in children. The best treatment in this research is was UB4.

    The purpose of this research is to obtain ratio of carrot and broccoli in making jelly drink. This is an experimental research which is use Complete Randomized Design (CRD) with 5 treatments, they are: WB1 (carrot 50 : broccoli 50); WB2 (carrot 60 : broccoli 40); WB3 (carrot 70 : broccoli 30); WB4 (carrot 80 : broccoli 20) and WB5 (carrot 90 : broccoli 10). The result showed that the ratio of carrot and broccoli in making jelly drink was giving real influence toward calcium, phosphorus, vitamin C and the assessment of organoleptic is the smell, but it gave influence unreal toward the assessment of color organoleptic, taste and whole assessment. The treatment of WB1 (carrot 50 : broccoli 50) gave the better jelly drink with calcium 50,95 mg/100 g, phosphorus 4,45 mg/100 g, vitamin C 49,68 mg/100 g, β-carotene 2,02 mg/100 g, the taste, smell and color whose the panelist like include the whole assessment.

    The aim of this research is to get the best quality of red seed guava’s syrup during storage with increasing the chitosan. This research use the Complete Random Design (CRD) with 5 treatments of increasing the chitosan (0%, 0.5%. 1.0%. 1.5%. 2.0%) and each of them is repeated by three times. The parameter which is observed were the level of sedimentation, the content of sucrose, the total of soluble solid, pH, viscosity, and organoleptic. The value of observation which is got analyzed with statistic. If F arithmetic is greater or equal with F table so done the next test by using Duncan test on 5% level. The results of this research shows that the increasing of chitosan on red seed guava’s syrup gave the significant effect to the number or total of soluble solid, pH, the viscosity more increase and content of sucrose, organoleptic more decreased. From the results of research which have done, got the average values of sucrose’s content is 65.81 to 70.21 the total of soluble solid is 70.80 to 80.80, the degree of acidity (pH) is 4.41 to 4.51. Viscosity from 75.01 to 226.60 and on k3, k4 and k5 there’s no grow ship worm to the the syrup which is produced during storage.

    Jelly candy is one form of diversification of products aloe vera and seaweed. This study aims to get the right ratio between aloe vera and seaweed to produce jelly candies with good quality. Parameters observed in this study moisture content, ash content, pH, reducing sugar content, crude fiber content and organoleptic testing the level of preference panelist on candy jelly with aloe vera and the ratio of seaweed. The study was conducted using a completely 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 vera and seaweed significantly effect on moisture content, ash content, reducing sugar content, and crude fiber content and not signoficantly effect on pH and the overall ratio of aloe vera and seaweed preferred by the panelists. The ratio of aloe vera and seaweed in the treatment LR4 (aloe vera 60% : 40% seaweed) is best treated with a moisture content of 16.44%, ash content 0.38%, pH 3.36, reducing sugar content 22.62%, crude fiber content of 1.44% and preferred by the panelists in organoleptic testing.
