Abstract

In everyday life the use of plastic materials is very dominant. The use of this plastic material from year to year has greatly increased, which has resulted in an increase in plastic waste. Various parties have conducted research to reduce plastic waste into something that can have added value, including converting plastic waste into alternative energy sources in the form of fuel. Handling of plastic waste can be done by recycling it by heating it in a reactor so that it becomes liquid oil, then the oil is purified using a distillation apparatus. This study aims to determine the performance of oil refining distillation equipment from the processing of Low Density Polyethylene (LDPE) plastic waste which can be used as fuel. The research method used is the performance test for refining oil from the processing of plastic waste which is heated with a distillation apparatus. Testing the plastic oil purification distillation apparatus was carried out 5 times, the test was carried out by means of each oil being put into the reactor totaling 3,500ml each time of testing, from the observations it showed that the results of tests 1 to 5 produced refined oil 1 = 1,592ml, 2 = 1.627ml, 3 = 1.609ml, 4 = 1.616ml, 5 = 1.319ml. The total amount of refined oil is: 7,768ml and the average temperature of the reactor is 184.6oC.

Abstract

Sandwich composites with a bamboo honeycomb core and coconut coir fibre face plates offer an alternative for lightweight structures that must absorb impact energy. This study examines the effect of coir fibre volume fraction in the face plate on the impact energy and impact strength of the composite. Fibres were alkali-treated in sodium hydroxide for one hour, then moulded with epoxy resin into 2 mm face plates at volume fractions of 30%, 40% and 50%. The core was assembled from bamboo strips into hexagonal cells of 10 mm cell side, 20 mm wall height and 1 mm wall thickness. Testing followed the Izod method of ASTM D256 with three specimens per fraction, and impact strength was taken as absorbed energy divided by the 136 mm² cross-section. Mean impact energy reached 6.93 J at 30%, 9.67 J at 40% and 7.50 J at 50%, equivalent to impact strengths of 0.0510, 0.0711 and 0.0551 J/mm². Scatter was wide, with standard deviations of 2.52, 5.80 and 3.32 J, and one-way analysis of variance gave F(2,6) = 0.37 (p = 0.71). The 40% composition is therefore best read as a working indication that needs confirmation with more specimens and tighter process control.
