Abstract

Hidram pump is one of the water pumps are energy efficient andenvironmentally friendly. Pump hidram an effective technology in the field ofenergy pumping by using the momentum of the water (water hammer) to raisethe water, so the pump hidram one water pump that does not use fuel andelectricity. Effectiveness hidram pump performance is affected by severalparameters such as the diameter of the pipe, reservoir height, exhaust valve, theair tube on hidram pump, inlet pipe length. This study aimed to observe andanalyze the effect on the length of the inlet pipe to the pump hidram highdischarge pumps and pumping. This research method through the design of thepump installation hidram and observation influence the inlet pipe length (6 m, 8m, 10 m), and the observation of the effect of the length of the exhaust valvespring (7 cm, 8 cm, 10 cm) to the pressure value (H) and the value of discharge(Q) to the pump performance hidram. The test is performed in ProductionProcess Laboratory August 17, 1945 University of Surabaya. The longer thepipe, the flow in the pump inlet hidram (Q) generated will be even greater. So inthe above study also directly proportional to the value of head (H) anddischarge rate (Q) on the pump performance hidram. So the value of theexisting pressure in the pump hidram with maximum value is generated headwith value - average (H) 1.41 bar and the discharge of water produced with -average (Q) 21 liters / min. This is because the moment of greatest impact onthe water valve.Keywords: Pump Hidram

Abstract

An electroless plating process that does not use electric current in the coating process. Coatings that occurs due to the reaction of reduction and oxidation of [ermukaan objects, thus forming a layer of metal derived from the metal salt. Because it does not use an electric current in the electron exchange coating process happens more slowly. The purpose of this study is to see the reaction products formed on the surface of coal bottom ash results electroless plating which is affected by variations in the weight of aluminum and temperature oxidation by testing the SEM-EDX. Results of SEM-EDX will be the reaction products formed by using statistical software version PCPDF WIN 2:01. From the test results SEM-EDX with magnesium weight variation and temperature variation affects the oxidation Wt%-forming elements in it but does not affect the elements formed where for all specimens produce similar reactions, namely Aluminium Silicate Al2SiO5.Keywords: Composites, electroless plating, the reaction products formed

Abstract

 Aluminium is a metal which has a mild nature, corrosion resistance, and electrical conductors that are used as matiks. Bottom ash coal used for reinforcement which is useful for producing aluminum composite with excellent mechanical properties and low cost. Besides the mechanical properties of aluminum can be enhanced by the addition of alloying elements (alloying) and the heat treatment process (heat tretment). The purpose of research is a comparative changes in microstructure before and after T6 heat treatment. This research will look at the changes in the microstructure of aluminum composite bottom ash coal that have undergone a process of T6 heat treatment that includes, (solid solution) is done at a temperature of 540 °C with a holding time of 6 hours, (quenching) with media cooling water, salt water (brine), oil, and (aging) with aging time of 2 hours, 4 hours, and 6 hours at a temperature of 180 °C From the results of tests performed on the aluminum composite material coal bottom ash, before and after T6 heat treatment process shows that. Granules greatest average diameter of the grain is shown by the media granules with salt water cooling 6-hour holding time for 165,3pm, and the smallest is 95,58pm with water cooling media holding time 6 hours, while aluminum composite granules of coal bottom ash without treatment equal to 158.4 pmKeywords: aluminum, coal bottom ash, heat treatment, quenching, aging, microstructure

Abstract

Heat treatment on the aluminum alloy is done by heating until a singlephase was then arrested a few moments and forwarded by rapid cooling to nothave time to change to another phase. If the material was left for a certainperiod of time then there was the process of aging (aging). Changes will occurin the form of precipitation (precipitation) The second phase begins with theonset of nucleation and atom clusters that became the beginning of theprecipitates. This precipitates can increase the strength and hardness. Thisprocess is the age hardening process called natural aging. If after rapid coolingthen heated again to below the solvus temperature (solvus line) then detained inthe long term and followed by slow cooling in the air called artificial agingprocess (artificial aging). This study aims to determine the microstructure ofwhat is formed from a material with a temperature variation of aging (200oC,225oC, 250oC) and holding time (8 hours, 12 hours, 16 hours) to determine howmuch influence the variables, can be analyzed through testing SEM EDXA.From the test results of SEM-EDXA it can be determined microstructure formedin 6061 + Al composite coal bottom ash, which is composed of aluminum oxidecompound of Al 2 O 3 and MgO.Keywords: microstructure, composites, coal bottom ash
