En 353 steel is an easily available and cheap material that is acceptable for heavy duty applications. Heat treatment on En 353 steel is improved the ductility, toughness, strength, hardness and relive internal stress in the material. X-ray diffraction (XRD) method is used to analyze the composition and the phase of the alloy material. The experimental results of hardness and microstructure are done to get idea about heat treated En 353 steel. It is found that the hardness of the En 353 steel is improved after the heat treatment and the microstructure is changed from ferrite to martensite.
Key words:En 353 steel, Heat treatment, Hardness, Microstructure.

Noise pollution has become a common problem in bigcities. Most of the noisegenerated the sounds of transportation and everything in the air. All of these noises on the highways impact to the increasing intensity of noise pollution. The research objective was to estimate the noise reduction using vegetation as a noise barrier in the highway along Waru - Sidoarjo. The present study was conducted on the highway alongWaru - Sidoarjo with existing vegetation at the side of the highway. A series of SLM(Sound Level Meter) was arranged at various distances from the highway, in the presence of vegetation, while another series was arranged in the absence of vegetation over the vegetation, the other series as control of those was placed without vegetation. Vegetation types used as samples wereSamaneasaman,Pterocarpusindicus,Tectonagrandis and Pithecellobiumdulce.From the measurement, noise reduction could be made created equal for each of the vegetation, so that estimation of noise reduction could be generated for specific distances. Theresult showed thatPithecolelobiumdulce havethe highest noise reductioneffectivity(P < 0.01) of 10.12% at 20 m distance.Noise was reduced when the location of the listener was away from the noise source and the noise reduction equation for this vegetation was y = 2.67 ln (x) + 2.18 with coefficient determination (R2) = 0.92.It was suggested that the settlement should be built more than 20 m away from the highway.
