Abstract

One alternative energy that can be developed is hydrogen. To obtain hydrogen gas by decomposing water compounds (H2O) into hydrogen hydrogen oxygen gas (HHO) through electrolysis. The solution used in this electrolysis process uses sodium chloride (NaCl) with electric current energy. In this research, a dry cell type HHO generator was used, the electrode used was a type 304 stainless steel plate with a catalyst percentage (NaCl) of 8%, 10%, 12%, 14% and 16%. The aim of this research is to determine the hydrogen content in a solution of vinegar and sugar water which can be used as an alternative fuel. This research produced the highest hydrogen volume at a percentage of 16% of 367 mL at the highest temperature of 547 C, the lowest 317 C and the lowest hydrogen volume of 198 mL. The highest flame height is 5.72 cm and flame width is 2.98 cm and the highest flame brightness level (Red Green Blue) is 16 RGB and the lowest brightness level is 2 RGB.

Abstract

Metal Matrix Composite is one of the metal composites that utilize aluminum alloy as a matrix in its fabrication. MMC has better specifications than the conventional materials it forms because it is light, ductile, with better hardness properties. The aluminum alloy as the matrix in this study has good mechanical properties but relatively low hardness values, especially type 2xxx aluminum containing Al-Cu or duralumin. By adding silicon carbide (SiC) ceramic content which acts as a filler in the manufacture of MMC it aims to increase the hardness value through a strengthening mechanism by analyzing the distribution of filler particles to the matrix. Using the sintering method with temperature variations that affect the mechanical properties of MMC. From the tests carried out the MMC specimens experienced an increase of 7.06% with the highest hardness value at 300oC sintering temperature of 71.6 HRB. With a SiC content of 14.42% Wt. Then it was observed using a Scanning Electron Microscope (SEM) that the distribution of SiC particles experienced an even distribution and bonded to the aluminum matrix thereby reducing porosity and increasing the hardness value of the MMC material.
