Abstract

Polyurethane is a type of polymer made by reacting polyol (OH) groups with isocyanate (NCO) groups. Thepurpose of this study was to determine the mechanical properties of a mixture of polyol and toluene sourcesas well as by adding the composition of activated carbon of palm shell as a filler to determine the best results.The materials used in making composites are PPG (Polypropylene Glycol), TDI (Toluent DiIsocyanate) andPalm Oil Shell Activated Carbon. Palm shells are carbonated at 600 ◦C, then made into powder using a ballmill and then sieved with 110 mesh particle sieve and activated using 10% H2SO4. FurthermorePolyurethanes are made by mixing, PPG (Polypropylene Glycol), TDI (Toluent in Isocyanate) with a ratio of60%: 40% and then added the activated carbon of palm oil shell as a filler with polyurethane: 95% activecarbon (P1), 90 %: 10% (P2), 80%; 20% (P3), and 75%: 25% (P4), then the functional group (FT-IR) andmechanical properties testing consisted of tensile strength and elasticity values. The results of thecharacterization of amine (NH), methyl groups (C-H3), Acetyl groups (CN), carbonyl groups (C = O),isocyanate groups (N = C = O), and Aromatic Rings (C = C) . This can be concluded after the addition ofactivated carbon palm shell does not cause chemical reactions in the functional group. While the results of thecharacterization of the tensile strength of P0 to P1 with a value of 0.1966 MPa to 0.0317 MPa, then increasedin the composition of 90 P2, P3, and P4 with values of 0.0985 MPa, 0.2318 MPa, 0.2981MPa, and finallyoccurred decrease again in the composition of P5. While the highest elasticity value on composites with aratio of P4 is 0.05196 MPa, while the lowest elasticity value on the composition of P5 with a value of 0.0475MPa.

Abstract

Palm Oil Factory Energy consists of steam and electricity. To increase the performance, energy will to beaudited. Electrical measurements are carried out at the power house, panels at each station and some electricmotors. Measurement in the main panel uses a power quality analyzer that can measure power, power factor,harmonics, unbalance and other electrical parameters. For measurement of mechanical equipment with steamenergy such as boilers and turbines using temperature measuring devices with infrared thermal imaging toolsFLIR brand. The quality of electric power with a total harmonic of 5.12% and individual harmonics of 2.78%.Voltage and current unbalance are 0.09% and 0.15%. Voltage drop is equal to 3 volts. The use of electricityutilities is 22.81 kW / ton FFB. The factory has cos phi of 0.84 but requires automatic power factor correction.The efficiency of boilers is 64.19% with the biggest losses being dry flue gas of 20.19% and oyher boiler of67.82% with the biggest losses being dry flue gas of 16.45%.

Abstract

The purpose of this paper is to calculate boiler performance by knowing energy losses during uap production.Technical analysis on the boiler is needed, as an effort to increase efficiency and know how much energy iswasted as a loss. Factors causing the greatest heat loss / heat loss in the boiler include: "heat loss due to dryflue gas, uap content in the flue gas, water content in fuel, water content in air supply and others". Heat loss /heat loss or also can be called energy loss is one of the important factors that is very influential in identifyingthe efficiency of the boiler.For that analysis study is carried out with the calculation of heat loss in order todetermine the magnitude of performance decline and the causes of decreased performance. Based on data andanalysis of the direct method it is known that the highest energy loss is 26.6% with an efficiency of 74.5%.There needs to be an improvement in the control of the fuel settings and the incoming air optimally by usingthe Oxygen Trim Control which functions to measure the oxygen concentration in the chimney andautomatically regulates the oxygen in the air entering the burner so as to produce combustion with optimalefficiency. And by using an economizer on preheating feed water temperature can increase boiler efficiency

Abstract

Briquettes are solid fuels that can be used as alternative energy. This research aims to determine the optimalratio of raw materials with adhesive content at about 10% constantly. The stages of this research were asfollows: 1) Sampling of raw materials, 2) Drying and decomposition of raw materials, 3) CarbonizationProcess, 4) Milling. 5) Composition Treatment, 6) Pressing and quality analysis of briquettes. The data of thisresearch were obtained by measuring calorific value, moisture content, ash content, density, compressivestrength, and combustion rate. The ratio between empty bunch : bagasse respectively was depended on100%: 0%, 75%: 25%, 50%: 50%, 25%: 75%, 0%: 100%. The Parameters of treatments were calorific value,moisture content, ash content, density, compressive strength, and combusition rate to find out the bestparameters. The result of this research shows the that the combination of empty bunch and baggase gave theeffect to the qualities. The highest calorific value was showed in the ratio empty bunch : baggase (100% : 0%)with average HHV value; the lowest average of moisture content ; the lowest ash content; density;compressive strength value; and combustion rate respectively 5889 cal/gr; 2,81%; 20%; 0,941 gr/ml;1,82N/cm2;0,00223gr/second.

Abstract

Deterioration of bleachability index (DOBI) reflects the paleness index of crude palm oil which has the aim ofremoving the color (bleaching) that is less favored in oil, so DOBI is quite important to assist processing inrefining palm oil. This study aims to determine the DOBI value contained in crude palm oil derived fromdifferent levels of fruit maturity namely unripped fruit, riped and overripe on oil palm at 850 meters above sealevel, as well as its stability on heating for 0 and 24 hours. The results showed that ripe fruit has a DOBIvalue of 1.75 and has better stability compared to raw fruit and through ripe.
