Abstract

This research was aimed for obtaining high level of yield in ethanol production from sorghum grain (Sorghum bicolor L.). Response surface methodology (RSM) is selected to optimize the process variables in ethanol production by employing Box Behnken design. The factors consist of Ammonium sulfate concentrations, shaking rates, and fermentation times, which are designed at 0%, 0.2%, 0.4%, 0 rpm, 50 rpm 100 rpm, 56 hours, 64 hours, 72 hours respectively. Second order polynomial model was developed by Design expert 07 to estimate the ethanol yield by different level for each factor and the regression square was 90.09%. Optimal solution in this work was determined by contour plot, with the highest yield was 39.55%(v/w) by combination of ammonium sulfate concentration, shaking rate, fermentation time are 0%, 31.69 rpm, 72 hours respectively.Keywords: box behnken, Fermentation, yield

Abstract

Nira merupakan bahan baku utama pembuatan gula merah. Nira siwalan mudah terfermentasi akibat aktifitas mikroba. Kerusakan nira harus dicegah dengan penambahan pengawet. Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan cabai rawit dan larutan kapur terhadap kualitas nira siwalan dengan menggunakan metode Rancangan Acak Lengkap Faktorial (RALF) yang terdiri dari 2 faktor yaitu cabai rawit segar dengan konsentrasi 3% (C1), 5% (C2) dan 7% (C3) dan penambahan larutan kapur 0,5 ml dengan konsentrasi 1% (K1), 2% (K2) dan 3% (K3) dan dilakukan pengulangan sebanyak 3 kali. Parameter penelitian yaitu pH, total padatan terlarut (TPT), total asam tertitrasi (TAT), turbiditas, aroma, kejernihan dan rasa. Hasil penelitian menunjukkan bahwa penggunaan cabai rawit segar berpengaruh terhadap pH, TPT, TAT, turbiditas, kejernihan dan rasa nira siwalan, namun tidak berpengaruh terhadap aroma nira siwalan. Penggunaan larutan kapur berpengaruh terhadap pH, TAT, turbiditas dan kejernihan nira siwalan, namun tidak berpengaruh terhadap nilai TPT, aroma dan rasa nira siwalan. Sedangkan  interaksi keduanya berpengaruh terhadap pH, TPT, TAT, turbiditas dan rasa nira siwalan, namun tidak berpengaruh terhadap aroma dan kejernihan nira siwalan. Palm sap is the main raw material of brown sugar. Fermented palm sap is due to microbial activity. Damage sap should be prevented by the addition of preservatives. This study aims to determine the effect of the use of cayenne pepper and a lime solution to quality sap of fan palm using completely randomized design factorial (Ralf) consisting of two factors: chili fresh with a concentration of 3% (C1), 5% (C2) and 7 % (C3), and the addition of lime solution of 0.5 ml with a concentration of 1% (K1), 2% (K2) and 3% (K3) and be repeated 3 times. Research parameter is pH, solids total that is dissolved (TPT), acid total that tritated (TAT), turbidity, aroma, clarity and taste. The results showed that the use of fresh red pepper effect on pH, TPT, TAT, turbidity, clarity and a sense of palm sap, but it does not affect the aroma of palm sap. The use of lime solution affect the pH, TAT, turbidity and clarity of palm sap, but it does not affect the value of TPT, aroma and flavor of palm sap. While their interaction effect on pH, TPT, TAT, turbidity and palm sap flavor, but does not affect the aroma and clarity of palm sap.

Abstract

The problem of obesity is a global problem that is being faced in the world. One of the precautions taken isfunctional food. Fermented soy milk is a functional food that has a hypolipidemic effect. The purpose of thisstudy was to analyze the relationship between the hypolipidemic effect of fermented soymilk and the contentof lactic acid bacteria in animal experiments. The results showed that the provision of fermented soymilkand unfermented soymilk could increase the total content of lactic acid bacteria in rat feaces. This is in linewith the decrease in total blood cholesterol levels in rats. Giving soy milk and fermented soymilk increasesthe total lactic acid bacteria in feaces thereby increasing cholesterol secretion in feaces

Abstract

Unripe jackfruit is one vegetables that  is usually processed into Indonesian dishs. Beside unripe jackfruit processed into vegetables can also be developed and processed into a dry product called beef floss. Unripe jackfruit has a very low protein content, so it needs other raw material to improve protein content of the floss we added tempeh to the floss = gembus tempeh or soybean tempeh, as much as 15%, 25%, 35% and 0% as control. This study uses a Completely Randomized Design (CRD) with 2 factors. The first factor is proportion of unripe jackfruit and tempeh, and the second factor is type of tempeh. Parameter of this research are organoleptic evaluation, the color, moisture content and protein content. The result of organoleptic evaluation is the proportion 25% soybean tempeh prefered for aroma, taste, color, texture. The highest L (Lightness) was resulted from 35% soybean tempeh. The highest moisture content was shown by floss with 15% soybean tempeh. Protein content increased from 4,3775% to 39,3975% by addition of soybean tempeh while protein increased from 4,3775%  to 14,8835% in beef floss added with gembus  tempeh.

Abstract

Snake fruit (Salacca edulis) can be made into dried fruit with addition of high concentration of sugar syrup prior to drying. This study aims to determine the effect of the concentration of sugar solution and soaking time on the characteristics of candied snake fruit. The experimental design used was a completely randomized design (CRD) factorial consisting of two factors: the concentration of sugar solution (40%, 50%, 60%) and the soaking time (24 and 48 hours). Each treatment was repeated three times. Data processing on quality of candied snake fruit was done using the General Linear Model (GLM) and univariate test of Duncan Multiple Range Test (DMRT). Results showed that concentration of sugar solution and soaking time gave significant effect on concentration of reducing sugar. Soaking at 48 hours significantly affectedyield, preferences for taste, texture, and overall preferences of candied snake fruit. Interaction of soaking and the concentration of sugar solution significantly affected moisture content of final product.

Abstract

Cassava peel is plenty agriculture residu because many food product use cassava asraw material, especially in Madura. The use of cassava peel is limited because of high cynideacid, low glucose, and low protein. The result of the first experiment shows that ragi tape is thethe most suitable ragi for fermentation cassava peel. The objective of this research is todetermine optimum fermentation time for cassave peel using ragi tape. The experiment havedone in laboratorium TIP UTM. Cassava peel fermented using 5% ragi tape until 9 days.Parameter of this experiment ar HCN content, protein, pH, and growth of ragi. The resultshows that optimum fermentation time is 6 days

Abstract

Characteristics by soaking dried candied jackfruit sugar rise. This study examines the rise of sugar immersion or not the characteristics of candied dried jackfruit. Research purposes to determine the concentration of sugar solution and the optimal level of immersion in the manufacture of sugar candied dried jackfruit. The design of the experiment used Completely Randomized Design with two factors: first giving the concentration of sugar solution 3 levels ie 30%, 40% and 50%. The second factor is the level of immersion that for a second soaking soaked in a solution with a higher sugar concentration is 40%, 50% and 60%. Observed variables are organoleptic test, water content, sugar content, sucrose content, and texture analysis. Data were analyzed using ANOVA (Analysis of Variance) Univariate followed by Duncan's test. Research and the level of sugar concentration and immersion significantly affect the color and moisture content. Texture analysis candied dried jackfruit only generate values of hardness and resilience. Highest hardness value sebesar6 candied dried jackfruit, 0120x10 3 on treatment B1A3 (1 time soaking in the sugar concentration of 50%), and the lowest at 5.8347x10 3 treatment B2A1 (2 times soaking in sugar concentration of 40%). Resilience highest value of 0.840 candied dried jackfruit obtained treatment B2A3 (2 times soaking in sugar concentration 60%) and the lowest in treatment B1A3 0.511 (1 time soaking in sugar concentration 50%). Characteristics best candied jackfruit contained on B2A2 treatment (soaking 2 times the sugar concentration of 50%.). B2A2 treatment has karkateristik 17.64% moisture content, sugar content mg/100ml 4.987, 34.0481% yield, hardness 5.9900 x10 3 Ng, resilience 0.540, and the value of a sense of (7.17), aroma (5.27), color (4.73), texture (4.9), and overall preference (4,47).
