This study aims to know the effect of acid type and concentration on the characteristics of liquid sugar resulting from the hydrolysis of yam gadung (Dioscorea hispida D.) and the highest DE value from the hydrolysis of the yam gadung starch. This research uses Randomized Block Design of factorial pattern. The first factor is acid treatment consisting of 3 levels: hydrolysis of starch with HNO3, H2SO4, and HCl and second factor is acid concentration consisting of 3 levels: 3%, 4%, and 5% . Each treatment is grouped into 2 based on execution time. The variables observed in this study were total sugar reduction, reducing sugar content, Dextrose Equivalent (DE), clarity, and total dissolved solids. The best treatment determination was done by analysis on DE value of hydrolysis result of yam gadung starch. The treatment of acid type variation was very significant and the acid concentration had a significant effect on the value of DE of hydrolysed yam gadung starch. The best hydrolysis treatment of starchy yam starch is by using chloride acid variation at 3% concentration with Dextrose Equifalent (DE) value of 41,22%.

The purpose of this reseach was 1) to determine the effect of temperature and acid type on hydrolysis of taro yam starch on the characteristics of glucose, 2) to determine the exact temperature and type of acid in taro starch hydrolysis which produced the best glucose characteristics. This reseach uses Randomized Block Design of factorial pattern.. The first factor is the hydrolysis temperature of taro yam starch at temperatures of 80°C, 90°C and 100°C. The second factor is the acids type of HNO3, H2SO4 and HCl, each with 7% acid concentration. Each treatment is grouped into 2 based on the implementation time. The variables observed were reduction in sugar content, total sugar, dekstrose equivalent (DE), total dissolved solids and clarity. The results showed that the temperature treatment and acid type had a very significant effect (P<0,01) on reducing sugar content, total sugar and hydrolyzed dectrose equivalent (DE) values. Temperature treatment has a significant effect on total dissolved solids and does not significantly affect clarity. The treatment of acid types has significant effect on total dissolved solids and clarity. Temperature treatment and type of acid interact with reducing sugar content, total sugar, and DE values, do not interact with total dissolved solids and clarity. The highest yield was obtained by reducing sugar content of 3,06%, total sugar 5,64% and DE value of 54,24% in HCl at 100°C. The total dissolved solids in H2SO4 and HCl at 100°C were 5,15°Brix and the clarity of HCl at 100°C was 0,02. The best glucose characteristics at HCl was 90°C which was not significantly different from HCl at 100°C. Keywords: sugar, hydrolysis, taro yam, starch, acid, glucose

This study aims to determine the most effective compound used to hydrolyze soy husk waste to produce reducing sugar as raw material for bioethanol fermentation. The study was conducted at the Laboratory of Bioprocess PPPTMGB "LEMIGAS" in April-September 2015. The method used is experiment using a randomized block design consisting of two factors. The first factor is the type of compounds used in the process of hydrolysis, namely H2SO4, HCl, NaOH, and NH3. The second factor is the concentration of hydrolyze compound 0.2%, 0.4%. 0.6%, 0.8%, and 1% (v/v) and every treatment repeated 4 times. Parameters measured were content of reduced sugar hydrolysis product, and secondary data that content of cellulose and hemicellulose also the density of ethanol. Concentration of reducing sugar from hydrolysis of soybean husk is analyzed by two-way ANOVA test. ANOVA analysis result indicate that the best hydrolysis compounds in hydrolizing soybean husk is HCl with the optimum concentration is 0,4%. And there are interactions between treatment of compound used to hydrolyze as well as concentration on reducing sugar concentration (mg/mL) as product from soybean husk waste hydrolysis. Post-hoc test showed that HCl 0,4% produce the highest concentration of reducing sugar at 31.23 mg/mL.

ABSTRACT<br />    <br />Sugar cane is a strategic commodity for the Indonesian government as raw material for the national sugar industry. Cultivation of sugar cane has been shifted to dry areas dominated by Inceptisol, Vertisol, and Ultisol soil. These conditions require certain clones to obtain high sugar yield. New improved varieties have been developed and 8 early-mid maturiting clones have been obtained. The study was aimed to evaluate and obtain earty-mid maturing clones with higher sugar yield than the existing varieties in dry land of Inceptisol soil. The study was conducted at the Karangploso Experimental Station, Malang from July 2015 to September 2016. The study was arranged in a randomized block design with three replications. The treatment consistsed of eight clones of early to mid maturing sugarcane clones and one control variety (Kenthung). The eight clones were (1) PS 04 117, (2) PS 04 259, (3) PS 04 129, (4) PS 05 258, (5) PS 06 391, (6) PS 06 370, (7) PS 06 188, and (8) JR 01. The results showed that three clones (PS 06 188, PS 05 258 and JR 01) produced higher sugar yield (10.45-11.88 ton ha-1), and the other clones showewd lower sugar yield (6.55-9.37 ton ha-1) than that of Kenthung variety (9.16 ton ha-1).PS 06 188 and PS 05 258 clones obtained the highest sugar yield of 11.88 and 11.49 ton ha-1, respectively.<br /><br />Keywords: dry land, performance, Saccharum officinarum,  sugar content, variety<br /><br />

Heterosis and its components were evaluated in a diallel crossing system of sweet corn. In the 38 treatments, eigth parents, 28 hybrids and two controls were used, arranged in a randomized block design with three replications.The diallel analysis followed the methodology of Gardner and Eberhart (1966). The following traits were evaluated: male and female flowering, plant and ear height, ear index (number of ears/number of plants), ºBrix, total ear weight, standard ear weight, industrial yield and total sugar content. There was genetic variability among genotypes, with significant differences except for the traits ear index, industrial yield and ºBrix.Heterosis was found for most traits. The mean heterosis of hybrids compared with the parents was positive for most traits. There was a contribution of additive and dominance effects.The contribution of dominant genes was greatest to flowering, plant and ear height and standard ear weight.

Whey cheese is a by-product of traditional or modern cheese-making processes. The yield of each cheesemaking reaches around 83% of the volume of milk used.whey can be processed into nata de whey by adding Acetobacterxylinum. The purpose of this study were to determine the effect of fermentation duration and differences in starter sources on the chemical quality produced by nata de whey. All samples were analyzed for fat, protein, cellulose and reducing sugars. this use study of two factorial randomized block design. The first factor is the difference in the starter (commercial and pineapple fruit extract) and the second factor is the length of fermentation with three replications. The results showed that the effect of fermentation time and the difference in starter sources on nata de whey had a very significant impact (P <0.01) on the calculation of fat content in the nata the whey. The duration of fermentation and differences in the source of the stater on nata de whey had no significant effect (P> 0.05) on the content of protein, reducing sugar and cellulose content produced.
