Abstract

The purpose of this research to investigate: (1) The effect of sparkplug types to exhaust gas emissions level of CO and HC on Honda Supra X 125 PGM-FI 2006motorcycle. (2) The effect of camphor addition  in premium to exhaust gas emissions level of CO and HC on Honda Supra X 125 PGM-FI 2006motorcycle. (3) The interaction of sparkplug types and camphor addition  in gasoline to exhaust gas emissions level of CO and HC on Honda Supra X 125 PGM-FI 2006motorcycle.  (4) Exhaust gas emissions level of CO and HC on Honda Supra X 125 PGM-FI 2006motorcycle after changed the sparkplug type and camphor addition  in premium. Based on experimental result can be concluded: (1) The using of sparkplug types and the variation of camphor addition in premium on Honda Supra X 125 PGM-FI 2006motorcycle gave the effect to exhaust gas emissions level of CO and HC. (2) The lowest exhaust gas emissions level of CO on standard sparkplug with 4 gram of camphor in 1 liter premium was 0.168%. The lowest exhaust gas emissions level of CO on platinum sparkplug with pure premium was 0.176%. The lowest exhaust gas emissions level of CO on iridium sparkplug with 4 gram of camphor was 0.176%. (3) The lowest exhaust gas emissions level of HC on standard sparkplug with 8 gram of camphor was 303 ppm. The lowest exhaust gas emissions level of HC on platinum sparkplug with pure premium was 311 ppm. The lowest exhaust gas emissions of HC level on iridium sparkplug with 8 gram of camphor was 380 ppm. (4) The lowest exhaust gas emissions level of CO and HC test with the interaction of sparkplug type and camphor addition in premium was using standard sparkplug and 4 gram of camphor adition in 1 liter premium.

Abstract

The purpose of this research: (1) Investigated the motorcycle exhaust emissions Suzuki Shogun FL 125 SP in 2007 used premium, pertamax,and pertamax plus. (2) Investigated the motorcycle exhaust emissions Suzuki Shogun FL 125 SP in 2007 used variation of compression ratio. (3) Investigated the motorcycle exhaust emissions Suzuki Shogun FL 125 SP in 2007 used interaction premium, pertamax, pertamax plus, and variation of compression ratio. Based on this researchcan be concluded: (1) The measurement premium fuel produced the lowest emission in CO 3.884% by 9.1:1 compression ratio and the the lowest exhaust gas emission levels in 168 ppm by 9.1:1 compression ratio. (2) The measurement pertamax fuel produced the lowest exhaust gas emission levels in CO 3.237% by 9.5:1 compression ratio and the the lowest exhaust gas emission levels in 210 ppm by 9.5:1 compression ratio(3) The measurement pertamax plus fuel produces the lowest exhaust gas emission levels in CO 2.615% by 10.2:1 compression ratio and the the lowest exhaust gas emission levels in 237 ppm by 9.5:1 compression ratio

Abstract

The purposes of this research are: (1) Analyze the effect of bentonite mixture variation at green sand molds to gray cast iron microstructure result of casting. (2) Analyze the effect of bentonite mixture variation at green sand molds to gray cast iron hardeness result of casting.(3) Analyze the effect of bentonite mixture variation at green sand molds to gray cast iron tensile strength result of casting.The research has donein the laboratory of Politeknik Manufaktur Ceper. This research does casting by using gray cast iron material. Techniques of data analysis in this research using descriptive data analysis that is directly observed experimental results are then analyzed and summing up the results of the research. As an input parameter in analyzing the data include: microstructure assaying, hardness and tensile strength.Based on result of inferential research that specimen microstructure at this research is casting result gray cast iron having metric of strong and firm pearlite. Flakegraphiteat specimen I (Bentonite 3%) harsher compared to specimen II (Bentonite 5%). Ferritein thespecimensImorethanferriteinspecimenII. Specimen I has pearlite structures which rather rugged, while specimen II has smooth pearlite. The hardness of gray cast iron owned by specimen II 66,5 HRA higher compared to hardness of gray cast iron owned by specimen I that is 55,8 HRA. Tensile strength at specimen II is 278,68 N/mm2 higher compared to specimen tensile strength I that is 222,92 N/mm2.

Abstract

The purposes of this research are : (1) To find out chemical composition and micro structure before and after welding using MIG method with PWHT on cast wheel aluminium. (2) To determines the hardness number, and the strength impact before and after welding using MIG method with PWHT on cast wheel aluminium. The research was conducted in INLASTEK laboratory Surakarta. The cast wheel aluminium of Honda Ferio was used to be sample on this research. The equipment that used for the chemical composition experiment, micro structure experiment, the hardness number experiment, and the strength impact experiment in succession are : Spectrometer Metal Scan, Olympus Metallurgycal Mocroscope, Brinell Hardness tester and Charpy tester. Based on the research results, can be conclude : (1) Chemical composition of Cast wheel alumunium was one of alluminium alloy Al-Si, due to Si is the main composition alloy that is 4, 61%. Based on micro structure of base material, Si were spread well around the surface of Al compared with the results after welding process with PWHT. (2) The hardness number on raw material is 42, 693 kgf/mm2, after PWHT treatment the hardness number on welding area becomes 29,062 kgf/mm2, HAZ area has hardness number are 23,487 kgf/mm2. The strength impact number on welding result using MIG with PWHT are 0,0717 joule/mm2 and on the raw material are 0,0924 joule/mm2. The experiments result indicate that, PWHT can switch over the micro structure, influent to the hardness number and strength impact on cast wheel aluminium. Specimen hardness and strength impack value of raw material is higher than MIG welding whit PWHT specimen.
