Clean air is a necessity for human. Human needs clean and healthy air without being contaminated by vehicle smoke that can endanger human health. vehicle smoke contains harmful substances for human including carbon dioxide (CO2), carbon monoxide (CO), nitrogen oxides (NOx) and lead metal (Pb). This can make air quality worse and can cause human be suffered of diseases including ARI (Acute Respiratory Infection), shortness of breath, sore eyes, coughing, brain damage and mental disability in children. Decision Support System (DSS) is a system to support Managerial decision makers in semi-structured decision situations and in this research author made a study of the DSS model to determine the level of danger of vehicle smoke, this study uses the Fuzzy Multiple Attribute Decision Making method (FMADM) where this method is a way to find optimal alternative from a number of alternatives with certain criteria, from very low things that was from 0-0.25, medium from 0.3-0.50, to the most dangerous thing that was from 0.8-1. Hopefully with the existence of this research later it can be useful for the community, especially for public health. � 2018, Advanced Scientific Research. All rights reserved.

In the composite industry, natural fibres have great potential to replace synthetic fibres like carbon and glass, due to their low cost and environmentally friendly materials. Bamboo is emerging as a versatile reinforcing fibre candidate because this woody plant has a number of advantages, such as being naturally strong, biodegradable and abundantly available. In this study, a compression test with a crosshead displacement rate of 1 mm/min was conducted on square and triangular honeycomb core structures based on bamboo-epoxy composites so as to study their specific energy absorption. Both square and triangular honeycomb structures were manufactured by the slotting technique. Initially, a tensile test with the same crosshead displacement rate was conducted to study the tensile strength of unidirectional bamboo-epoxy composites with 0�, 45� and 90� fibre orientations. Bamboo-epoxy composite laminates were fabricated by applying a hand lay-up technique. The experimental data showed that the unidirectional bamboo-epoxy composite with 0� orientation offered the highest tensile strength. This indicates that the bamboo is stronger when parallel to the tensile axis. Meanwhile, the triangular honeycomb bamboo-epoxy structure offered about 10% more energy absorption than the square honeycomb structure, which indicates that the smaller cell size of honeycomb is able to absorb more energy than the bigger one. � Universiti Malaysia Pahang.
