<p>The purpose of this research was to determine the effect of substitution of acetic acid modified breadfruit flour with the addition of pandan leaves extract against physic, chemical and sensory characteristic of crackers and determine their antioxidant activity on crackers. This study uses a Completely Randomized Design (CRD) with one factor substitution of acetic acid modified breadfruit flour. Sensory data were analyzed by one-way ANOVA, if there is a difference it was followed with significance test using Duncan’s Multiple Range Test (DMRT) at significance level of 0,05. The results showed that substitution of acetic acid modified breadfruit flour did not significantly affect the physical characteristic (hardness), chemical characteristics such as moisture content, ash, protein, carbohydrate and antioxidant activity of crackers. However, the substitution of acetic acid modified breadfruit flour affected the levels of fat, crude fiber, sensory characteristics (colour, flavor, taste, texture and overall) of crackers. The antioxidant activity of crackers is about 3.27%-4.16%.</p>

ABSTRACT                     This study aimed to analyze the effect of lindur fruit flour substitution on organoleptic characteristics, nutritional value, and antioxidant activity of lindur fruit flour brownies. This research was conducted using a completely randomized design (CRD) with various percentages of formulation of substitution of lindur fruit flour:wheat flour, namely M1 = (100%:0%), M2 = (90%:10%), M3 = (80%:20 %), M4 = (70%:30%), and M5 = (60%:40%). The research data were analyzed using analysis of variance, with further testing using Duncan's Multiple Range Test (DMRT) at a 95% confidence level. The results show that the HCN content of lindur fruit flour reached 21.81 mg/kg. The M3 treatment was the most preferred treatment by the panelists with hedonic rating scores of color, texture, aroma, and taste reached 4.14 (like), 4.13 (like), 3.79 (like), and 4.30 (like), respectively. The nutritional values of selected M3 brownies show that it contained 30.57% water, 1.20% ash, 3.70% fat, 5.63% protein, and 58.90% carbohydrate. Analysis of antioxidant activity in selected M3 brownies was 465.58 ppm which is categorized as very weak. It can be concluded that the substitution of lindur fruit flour in making brownies had a very significant effect on color, texture, and taste. However, the effect was not significant on the aroma and the analysis of the nutritional value of the selected treatment. The brownie product substituted with lindur fruit flour met the national standards for water, ash, and fat contents.Keyword: Brownies, Lindur Fruit ABSTRAK    Penelitian ini bertujuan untuk mempelajari pengaruh substitusi tepung buah lindur terhadap karakteristik organoleptik, nilai gizi, dan aktivitas antioksidan brownies tepung buah lindur.

Plants that can be used as pesticides are Gadung tubers. Gadung tubers contain cyanide acid to kill armyworm pests because they contain dioscorin toxins which can cause nervous disorders. The purpose of this study was to determine the effect of Gadung tuber extract (Dioscorea hispida) on Caterpillar mortality (Spodoptera exigua) in Shallot plants. This type of research is experimental research. This study used a completely randomized design (CRD). The sample used was 5 caterpillars (Spodoptera exigua) in each polybag with 5 repetitions for each concentration of Gadung tuber extract, namely 0%, 0.5%, 1.0%, 1.5%, 2.0% and 2.5%, so the total Caterpillar used was 150 Caterpillars. Gadung tuber extraction was carried out by maceration method with methanol solvent. Data were analyzed using a one-way analysis of variance at the 95% significance level, followed by DMRT (Duncans Multiple Range Test). The results showed that the Gadung tuber extract had a significant effect on the mortality of caterpillars (Spodoptera exigua) because the F count was greater than the F table (45.40>2.62), and the DMRT test results showed that the optimal concentration of Gadung tuber extract was 2.5%. Therefore, it can be concluded that the extract of Gadung tuber (Dioscorea hispida) affects the mortality of Caterpillars (Spodoptera exigua) in Shallots (Allium cepa).

Sweetener is one of important factors which affect consumer acceptance as it affects the ice cream texture. Research on an alternative and healthier sweetener to substitute sugar in ice cream production has begun to emerge as consumers’ awareness on healthy food has been increasing. One of the promising alternatives was the utilization of Stevia leaf powder as it is known to have no calorie content. In this research, the best proportion of stevia leaf powder to substitute sugar in ice cream production was determined based on its physicochemical properties (viscosity, overrun, melting rate, sugar and total calories) and antioxidant activity. The research was done through laboratory experiment with a Completely Randomized Design consisted of four sugar and stevia leaf powder combinations and four replications. The treatments were P0 (20% sugar + 0% steviea leaf powder); P1 (17.5% sugar + 0.3% stevia leaf powder); P2 (16.25% sugar + 0.45% stevia leaf powder); and P3 (15% sugar + 0.6% stevia leaf powder). The obtained data was analyzed by ANOVA and further tested by Duncan’s Multiple Range Test upon significant effect.The results showed that the utilization of stevia leaf powder as sugar substitution gave highly significant effects (P<0.01) on ice cream viscosity, overrun, melting rate, sugar content, total calories and antioxidant activity. It can be concluded that the combination of 15% sugar and 0.6% stevia leaf powder (P3) produced the best ice cream characteristics with the viscosity of 1336.25 cP, overrun of 30.01%, melting rate of 37.24 minutes/50 g, sugar content of 34.63%, total calorie of 4.99 kcal and antioxidant activity of 81.92%.

The research aims to observe the effect of addition wild honey (Apis dorsata Fabr.) on pH and organoleptic values of ultra high temperature milk (UHT). The research was  done using an experimental method using a non-factorial completely randomized design with five levels using SPSS 16. Different concentrations of wild honey (A1= control; A2= 5%; A3= 10%; A4= 15% and A5=20%) were used. The data was statistically analyzed using analysis of variance (ANOVA) with 5% significance level and further processed with Duncan's Multiple Range Test (DMRT). Organoleptic tests for colour, taste and overall preference were also done using qualitative tests (scores). The value of pH gave a significant value (P<0,01) between treatment. The higher the use of  wild honey concentration, the lower the pH value produced. The higher the concentration of wild honey, the higher the organoleptic value. The best treatment in terms of colour, taste, and level of preference was observed in the sample with the 20% honey concentration, each of which resulted in an average score of 4.
