Abstract

This research was started by pirolized the  main  matter, nyamplung’s seed peel into char with three kinds of adhesive agent as is sodium silicate, wheat powder, and tapioca starch. The aims of this research are to know the right kind of the adhesive, to know the optimal particle size of the nyamlung seed’s peel ash, to know the optimal of  the adhesive concentration, and to know the optimal condition of the briquette making by using response surface methodology (RSM). This research uses two steps, first is first is certaining the right kind of the adhesive agent and second one is optimization of independent variables as are the concentration of adhesive agent and the char particle size. The result of this research shows that the best kind of adhesive agent which is used to produce a good briquette is tapioca starch. Briquette with 17,66% adhesive agent and 20 mesh particle size results  the highest heating value as is 6772,582 kal/gr  which has fulfilled the  standart of Indonesian and Japanese. Briquette with 6,34 % adhesive agent and 20 mesh particle size results  the worst stabilty and the highest % loss as is 33,56 % while briquette with 16 % adhesive agent and 40 mesh particle size also 17,66 % adhesive agent and 20 mesh particle size results the best stability and the lowest % loss consecutively as is 0,83 % and 1,24 %. Stability test shows that briquette product is stable in diameter and height all the time. From this research’s results, it is wished to take a further research that study about the other independent variables to produce the better nyamplung’s seed peel briquette so it can give a contribution for inventing alternative enviromental agreeable fuel.

Abstract

Modernite very well used as an acid catalyst for the cracking process, to get a good acid levels can be modified catalyst by dealumination process. Dealumination will provide a ratio of Si / Al higher which can provide the catalyst selectivity and activity of catalysts are higher and more stable than modernite the ratio of Si / Al 20. In this study, using raw materials such as used cooking oil and zeolite catalysts modernite types. In an influential study variable, didapaatkan equations for liquid products is Y = -120.858 + 4.869 + 1.473 X1 + X2 + X3 59.183 0.043 X1X2 - X1X3 0.733 - 0.320 X2X3 - X1 0.324 2 to 0.008 X22 - X32 6.075. As for the product gas mathematical equation is Y = 122.3022 + 1.5447 X1 - 0.8713 X2 + X3 + 55.8804 0.0357 X1X2 - 0.8281 X1X3 - X2X3 0.0547 - 0.0643 X12 + 0, 10.7038 + 0076 X22 X32, the Y is the yield resulting product, X1 is a dealumination, X2 is the operating temperature, and X3 is the concentration. Optimal conditions maximizing the type contained in the concentration versus time relationship, with a time of 8 hours and a concentration dealumination 3 N for liquid products, while for the product gas at 8 hours with an operating temperature of 50 ° C.

Abstract

This research engages banana peel as the source of cellulose for hydrolysis into glucose using sulfonated activated carbon as catalyst. The aims of this research are to study the effect of hydrolysis temperature, hydrolysis times, and the weight of catalyst, to conclude the mathematical model plotted from the yield and the variables, and to conclude The optimum conditions for hydrolysis of banana peel cellulose into glucose which includes hydrolysis temperature, hydrolysis times, and the weight of catalyst.                This  research is designed into two steps, the sulfonation of the activated carbon and the hydrolysis of banana peel cellulose. H2SO4 10 N is used for the sulfonation which is done in 6 hours at 40oC. After the catalysts are dried and calcinated, the catalysts are ready for the hydrolysis precesses which are done in the autoclave batch reactor. After that, spectrophotometer is used to analyze the sample. The results was plotted on a mathematical model and then optimized using the software Statistica 6.0 by Response Surface Methodology method (RSM).                 The result obtained by a mathematical model for relationship activator combination temperature, time and weight of catalyst for content glucose Y = 3,035+0,18 x1 + 0,04 x1² + 0,089 x2 + 0,012 x2² +0,047x3 – 0,021 x3² – 0,014 x1x2 – 0,087 x1x3 + 0,022 x2x3. The optimum conditions of hydrolysis variable for glucose obtained by statistica 6.0 software which the graph fitted response surface and contour plot indicates the optimum hydrolysis temperature is in the range 112°C to 115°C, the optimum hydrolysis time is in the range 300 minutes to 500 minutes, and the optimum weight of catalyst is about 30 gr which the sample contains 3,6 mg/ml of glucose.

Abstract

This research engage water hyacinth (Eichhornia crassipes) as source of cellulose for hydrolysis into glucose using sulfonated activated carbon as catalyst. The aimsof this research are to know optimum conditions for hydrolysis water hyacinth into glucose which includes hydrolysis temperature, hydrolysis times, and the weight of catalyst. This research design uses three steps, first is making catalyst,then hydrolysis of cellulose and the last is testing content glucose of filtrate. The data results was plotted on a mathematical model and then optimized using the software Statistica 6.0 by Response Surface Methodology method (RSM). The result obtained by use of a mathematical model for relationship activator combination temperature, time and weight of catalyst for content glucose : Y = 11,601+2,353 x1 – 1,041x1² + 2,463 x2 – 1,554 x2² -2,847x3 – 1,316 x3² + 0,025 x1x2 - 0,885 x1x3 + 0,228 x2x3. The optimum conditions of hydrolysis variable for content glucose obtained from the graph fitted response surface and contour plot that indicates optimum hydrolysis temperature in the range 130°C to 170°C, the optimum hydrolysis time in the range 130 minutes to 210 minutes, and weight of catalyst in the range 3 gr to 20 gr.
