Abstract

Plastics are synthetic polymer compounds formed from the polymerization of small molecules(monomers) composed of hydrocarbon bonds. The use of plastic waste as a material to produce fueloil is an alternative that can increase the economic value of plastic waste, besides that it can alsosolve one of the environmental problems. This study aims to analyze the characteristics of fuel oilproduced from plastic waste type High Density Poly Ethylene (HDPE) with the pyrolysis process. Theresearch methodology variables include; the pyrolysis time was 120 minutes and the pyrolysistemperatures were 390oC, 410oC, 430oC, and 450oC. The test of the pyrolysis oil is based on theflash point. Furthermore, the calculation of the reaction kinetics using the Arrhenius Equationmethod. The optimum temperature for HDPE plastic pyrolysis is at a temperature of 450°C with aconversion efficiency of 59.3% wt. The value of the reaction rate constant obtained is k = 7.3 x 109 .e(117.013/R.T).

Abstract

The facilities used by Posyandu cadres in weighing and measuring the height of children under five are not sufficient, because apart from that, they are not feasible nor are they calibrated accurately. Especially for measuring the height of toddlers, so far the posyandu generally still use the manual method, Based on this background, a digital height measuring device was designed in order to refer to the mission of the Unisma Bekasi Faculty of Engineering in an effort to increase the quantity and quality of community service (PPM) in the field of applied technology (appropriate technology), so this program was implemented. The PPM partners targeted for this program are Posyandu Kemuning cadres, Jatirasa Village, Jatiasih District, Bekasi City. The results of the design of this tool complete the automatic height measurement which is quite satisfactory at the Kemuning Posyandu, Jatirasa Village, Jatiasih District, Bekasi City. Development of a baby height and body mass measurement tool based on the ATmega 8535 microcontroller by utilizing a phototransistor sensor.
