Abstract

The purpose of this study was to look at the effect of sugar dose, black tea extract dose, interaction of sugar and black tea exstract dose on the fermentation and production of nata de coco. Completely Randomized Design (CRD) in Factorial was used in this experiment with sixteen treatments and two replications. The first factor was the doses of sugar and the second factor was doses of black tea extract. The results of this study showed that the doses of sugar and addition of black tea extract was able to increase the production of nata de coco. The best dose of sugar in 50 g/ l, the best dose of black tea extract in 8 g/ l. The interaction of sugar dose and black tea extract dose contained in the treatment a1b2 the dose of sugar 50 g/l and black tea extract 8 g/l with an average weight of 23,43 g nata de coco. The benefits of this research is to increase production and quality of nata for the nata de coco’s industry.

Abstract

Production of waste in urban areas reached 0.5 kg/person /day and 80% consisted of organic waste, one of many types of waste mostly generated is household waste. Generally, this household organic waste containing structural compoundsuch us long chains of cellulose.Therefore, the use of microorganism that can produce cellulase is very important to reduce the weight of garbage. Trichoderma harzianumis known as the most potential mold compared to other molds in converting cellulose. Sawdust and bran contain cellulose and hemicellulose that can be used as the main component in the mediafor its growth. The objectives of this study was: To find an effective ratio between sawdust and bran as growth mediafor Trichoderma harzianum, To know the cellulase activity of Trichoderma harzianum. This study has been conducted from April 2015 to Juli 2015 in the Laboratory of Microbiology, Department of Biology, Faculty of Mathematics and Natural Sciences, University of Andalas. The results of this study concluded that an effective ratio between sawdust and bran as a growth media for Trichoderma harzianumwhich degraded organic waste was 50:50. The highest activity of cellulase in degrading organic waste is 100%.

Abstract

Research on the mycelial growth of mold isolates lignocelulolitic done using media substrate bran and sawdust. This research was conducted from April 2015 through March 2016 in the laboratory of Microbiology/ Mycology Department of Biology, Faculty of Mathematics and Natural Sciences, University of Andalas. This study aimed to compare the media effectively to the growth of mold isolates lignoselulolitik and lignin peroxidase (LiP) activity it generates in the response to the lignocellulosic organic waste. Comparison of media composition adapted to the treatment used is Bran 100%: Sawdust 0%; Bran 75%: Sawdust 25%; Bran 50%: Sawdust 50%; Bran 25%: Sawdust 75% and Bran 0%: Sawdust 100%. Parameters include the observation of mold growth on medium speed baglog and lignin peroxidase (LiP) activity was measured using a spectrophotometer at a wavelength of 310 nm with Veratryl Alcohol as a substrate. The results showed that the ratio of the bran media effectively : sawdust against mycelial growth of mold isolates are on treatment lignoselulolitik bran 75% : sawdust 25%, while the activity of lignin peroxidase (LiP) at the highest bran ratio of 50% : 50% sawdust.
