IDENTIFICATION OF PHENOL COMPOUNDS OF LIQUID SMOKE SHELL OIL AT HIGH TEMPERATURE PYROLYSIS
Get PDFThe aim of this study was to determine the content of phenol in the liquid smoke palm kernel shells produced at a temperature 600?C, 700?C, 800?C. Pyrolysis process was carried out by using a furnice that surrounding covered with fire-resistant white cement so that the smoke does not escape into the air and liquid smoke produced more leverage. Temperatures used 600?C, 700?C, 800?C use with condenser-type spiral coil number of turns 30. Liquid smoke produced in deposited for 7 days and in the centrifuge with a rotation speed of 3800 rpm for 60 minutes, filtered and distilled at 125?C temperature for 60 minutes. Liquid smoke analyzed (characterization) using GC-MS and phenol identified for each temperature 600?C is 35.09%, the temperature 700?C is 37.962% and 37.494% temperature 800?C is.Keywords: Liquid Smoke, Phenol compounds, GC-M
OPTIMASI MODEL HIDROLOGI MOCK DAERAH TANGKAPAN AIR WADUK SEMPOR
Get PDFHydrological analysis is an important stage in water resources development activities, where the output of the analysis will give an overview about water discharge (inflow) into reservoir which is hopefully the quantity of water can supply all human needs (outflow) and also determine the direction of water resources development strategy in a comprehensive indirectly. Utilization of Mocks hydrological model is an approach to simulate and forecast the hydrological phenomenon that is occuring in the future using certain hydrological data recording. The main input of Mocks hydrological model are semimonthly precipitation, evapotranspiration and parameters, while the output of model is water discharge. Microsoft excel was used in analysis of data. The optimal parameters of Mocks hydrological model for regional water catchment area of Sempor Reservoir was obtained through the stages of calibration, verification and validation. The optimal parameters are water catchment area 44.158 km2; wet season infiltration coefficient 0.25; dry season infiltration coefficient 0.4; initial soil moisture 100 mm; soil moisture capacity 150 mm; initial groundwater storage 500 mm; groundwater recession constant 0.995.Keywords: Mocks hydrological model, water discharge, Sempor Reservoi

Get PDFThe research of grafting methyl methacrylate onto Cyclized Natural Rubber has been carried out. Dicumyl Peroxide was used as a inisiator and temperature condition at 90oC with variation of time 1 and 2 hours. Grafting process was done with technique of reflux in a tree-neck flask with condenser and oil bath. Spectra analysis FTIR performed for determine the presence of grafted MMA on the backbone of CNR. The results showed that the product CNR-g-MMA was formed with the marked appearance of the absorption peak wave numbers at 1731 cm-1 (carbonyl group absorption) typical for carbonyl (C = O) of methyl methacrylate. The degree of grafting increased with the increasing time grafting.Keywords: grafting, cyclic natural rubber, mathylmetacrilate, dicumyl peroxid
