If more or less too a little texture with flexibility. Study the quality of bacterial cellulose from palm sugar has found a physical quality thickness 1.50 centimeter weight 830 gram. pH-value equal to the value 4.80 of the sweetness equivalent to 11 Brix chemical quality found that the quantity of 100 gram Bacterial cellulose products palm sugar showed that the energy 133 kilocalories Carbohydrate 32.80 gram protein< 0.21 grams fat 1.25 grams of moisture 67.00 grams and fiber 0.69 grams the study found that in side to accept the appearance color smell taste texture and overall preference. This equals an average 4.39 4.41 3.66 4.33 4.40 and 4.28 respectively of the consumers. It found that consumers accepted tasting bacterial cellulose products palm sugar 100 percent. Palm sugar Ready to drink products mixed Bacterial cellulose palm sugar. The basic formulation of palm sugar formulations 3 and with the highest score on every side. Due to the muddy liquid palm sugar the natural flavor of adopting. Bacterial cellulose content was suitable 15 percent and the amount of pectin found that 3 percent is the optimum because the pectin substances causing gel. If there is a lot of water quantity will be thick and viscous too. Do not be the good characteristics of palm sugar is ready to drink. Physical analysis it was found that the quantity of the acid-base 6.5 the sweetness 16 degrees Brix. And the chemical analysis showed that the energy 60.4 kilocalories carbohydrate 15.1 grams protein less 1.25 grams fat 0 g fiber 0.39 grams and Ash 0.27 grams. The (5) adoption of palm sugar products ready to drink mixed bacterial cellulose it is found that the appearance of color smell taste texture (viscosity). And preference overall average of the 4.39 4.41 3.66 and 4.33 4.40 4.28 respectively. Consumer acceptance of Ready-to-drink products palm sugar mixed Bacterial cellulose palm sugar 150 people representing 88.76 percentage.

This paper presents an analysis of transformer faults to determine the damage occurring within the transformer by the frequency response analysis (FRA) method. Enter the frequency from 10 Hz to 3 MHz and then the measured value is compared to the standard reference value. Consider the different graphs of frequency response in various frequency ranges to analyze the deformation of the iron cores and transformer coils to know the internal condition of the transformer. The tests show that the 50 MVA 115 kV/22 kV transformer has severe damage to the high voltage side and low voltage side of phase-A coil. As a result the transformer can not be used in the power system and make a reminder to repair the transformer.
