Abstract

Biodisel methyl ester research has been used waste cooking oil and methanol with ash replenishment as acatalyst.This research was doing to saw the effect of catalyst concentration on biodiesel from used cookingoil. The research used a Completely Randomized Design with five treatments is M1 (catalyst 2 g), M2 (catalyst4 g), M3 (catalyst 6 g), M4 (catalyst 8 g) and M5 (catalyst 10 g) withing three replications. The data wereanalyzed using Analysis of Variance (ANOVA) and continued with DNMRT at 5% level. The research resultshas showed that the addition of a catalyst concentration of ash significantly (P<0,05) affected on the acidnumber, total glycerol content, density, saponification number, viscosity, iodin number, flash point and levelmethlyl ester, but did not significantly influence (P>0,05) on the water content. The best treatment is M5 withacid number 0,71 mg KOH/g, total glycerol content of 0,01%, density 0,88 g/cm3, viscosity of 47,94 cSt, iodinnumber 66,83 gI2/100, water content of 0,06%, flash point 249,33°C, saponification number154,84 mg KOH/g and levels of methyl ester 99,5%.

Abstract

This research was carried out for to see the addition of tapioca and sago starch nutrient content nuggetaccording to SNI 01-6683-2002 and see the characteristics of sensory attributes preferred by consumers andget the best position for five products nugget from the consumer side. This study was conducted experimentswith five treatments and three replications. The combination of these treatments is TSB1 (15% tapioca, sago0%), TSB2 (10% tapioca, sago 5%), TSB3 (7,5% tapioca, sago 7,5%), TSB4 (5% tapioca, sago 10 %) andTSB5 (0% tapioca, sago 15%). Sensory analysis was performed hedonic test (consumer acceptance) anddescriptive test. The addition of tapioca and sago starch in the manufacture nugget eel meet the qualityrequirements contained in SNI 01-6683-2002 as the water content is 36,76-38,49%; protein 13,54-13,98%fat and 16,93-17,38%. However, the carbohydrate content has not fulfilled SNI namely 28,64-30,20% andash content was obtained 1,95-2,12% of unknown quality standard in SNI 01-6683-2002. The level ofconsumer preferences towards nuggets eel preferred by preference mapping is treated TSB1 (tapioca 15%;sago 0%) and TSB2 (tapioca 10%; sago 5%) with the quality attributes of texture (hardness), taste pepper,brown color and flavor sweet nuggets while most preferred is the treatment TSB3 (tapioca 7,5%; sago 7,5%)with the quality attributes onion aroma, the smell of garlic, pepper aroma, the scent of fish, fish flavor, garlicflavor and taste of onion.

Abstract

The research aims to observe and obtain a better concentration of powder extract citronella grass leaf tocontrol anthracnose disease on red chili fruits. The research has been conducted experimentally using acompletely randomized design, consisted of 6 treatments and 4 replications thus obtained 24 trial units. Theresearch consisted of two phases: in vitro inhibition of C. capsici and in vivo application of powder extractcitronella grass leaf on red chili fruits. The concentration of powder extract citronella grass leaf used are:S0= 0 g/l, S1= 50 g/l, S2= 100 g/l, S3= 150 g/l, S4= 200 g/l dan S5= 250 g/l of water. The data werestatistically analyzed using analysis of variance and the means were tested with Duncan ‘s New MultipleRange Test (DNMRT) at level of 5%. The results of the research showed that the concentration of powderextract citronella grass leaf at 200 g/l of water tended to show a better ability to inhibit the growth of C.capsici at in vitro phase with growth inhibition up to 22,26%.Key words: Red chili, C. capsici and Cymbopogon nardus L.

Abstract

The aim of this study was to explore the processing of jamblang (Syzygium cumini) fruit into syrup. Moreover,the effect of water and fruit ratio, and sugar concentration on the characteristics of the syrup was investigated.This study was conducted using a completely randomized design factorial consisting of two factors: the ratioof water and fruit (2: 1, 1: 1, 1: 2) and the concentration of sugar (65%, 75%, 85%). The results showed thatthe best quality of the syrup based on organoleptic tests obtained from the treatment combination of waterand fruit ratio = 1: 1 with a sugar concentration of 65%. After pasteurization, the syrup had a pH value of3.89, total sugar of 88.70%, anthocyanin content of 29,73 mg/100 g, antioxidant activity of 58.74%, vitaminC content of 7,04 mg/100 ml and panelists liked its color, aroma and taste.

Abstract

The purpose of this study was to determine the effect of using sago starch, tempe flour and purple sweet potatoflour to the characteristics physicochemical and sensory of the cookies and meet the quality standard ofcookies (SNI 01-2973-1992). The research used a Completely Randomized Design (CRD) with five treatmentand four replications. The treatment in this study were K1 (sago starch 100%), K2 (sago starch 60%, tempehflour 20%, purple sweet potato flour 20%), K3 (sago starch 50%, tempeh flour 25%, purple sweet potato flour25%), K4 (sago starch 40%, tempeh flour 30%, purple sweet potato flour 30%), K5 (sago starch 30%, tempehflour 35%, purple sweet potato flour 35%). The data obtained were statistically analyzed using analysis ofvariance (Anova). If F count is greater than or equal to F table, then conduted a further test with Duncan’sNew Multiple Range Test (DNMRT) at the level of 5%. The results showed that the treatment significantlyeffect to the moisture content, ash content, protein content, analysis texture, descriptive sensory assessmentand hedonic sensory assessment and non significant on the overall hedonic ratings. The best cookies in thisresearch is was K3 with has 2.95% of moisture content, 1.14% of ash content, 8.86% of protein content 4.30kgf of texture, coloured purple, sweet scent purple sweet potato, slightly brittle texture and having sweetness.
