Get PDFThe use of a steam carburetor is one way to reduce exhaust gas emissions where it works by mixing fuel and air in the room with an evaporation process so that the air and fuel mixture is more homogeneous. This study aims to see (1) the effect of using a steam carburetor on exhaust gases on a Supra X motorcycle; (2) the effect of using variations in exhaust gas emissions on the Supra X motorcycle; (3) the effect of using steam carburetors and fuel variations on the exhaust emissions of the Supra X motorbike. This research is a research, quantitative, descriptive, comparative, with experimental methods. The research used the 2x2 method which consists of independent variables using steam and conventional carburetors as well as variations of pertalite (RON 90) and pertamax (RON92) fuel. Exhaust gas emission testing is guided by the Indonesian National Standard (SNI) with three repetitions, for 20 seconds times the test The results of the study are as follows: First, the use of a steam carburetor produces lower exhaust emissions compared to conventional carburetors on a 100cc Supra X motorcycle. Second, pertalite fuel (RON 90) produces lower exhaust emissions compared to Pertamax fuel (RON 92). Third, the effect of using the type of carburetor and the type of fuel that produces the lowest exhaust emission, namely the steam carburetor using the combined splash and bubbling method with pertalite fuel with an average of 0.52% CO and 273.67ppm HC.
KUALITAS REPAIR WELDING MENGGUNAKAN METODE PENGELASAN TIG DENGAN PERLAKUAN PREHEATING DAN POST WELD HEAT TREATMENT PADA CAST WHEEL ALUMINIUM
Get PDFThe Purpose of this research are to know chemical composition, find micro structure, find impact strength, find speciment’s hardeness level on allumminium cast wheel before and after Tungsten Inert Gas welding. The speciment on this research is aluminum cast wheel or aluminum velg. The data analysis on this research is a comparative descriptive method, that the observation result is analyzed by description. And then compare the observation result between the data before TIG welding or before conducted preheating and PWHT. The parameter of analyze data are included: the testing of chemical composition, microstructure, hardness and impact. Based on the result of this research, it can be concluded that the cast wheel material is aluminum type cast alloy AA.445.2 which has non-heat treatable characteristic. The research results show that the microstructure of Al grain in the HAZ region fused with primary aluminum (α-Al) and grain Si alloy formed between the primary α-Al. The impact strength value on the welded speciment is higher than impact strength value before welding those are 0.0616 J/mm2 and 0.0384 J/mm2. Hardeness level on the speciment before welding processes is 103,381 VHN. The number is higher than after on the welding area, the hardeness level is lower too that is 44,051 VHN, whereas the hardeness level an the HAZ is a 37,943 VHN and 35,465 VHN on the base material
