Abstract: PENGARUH UNSUR SILIKON PADA ALUMINIUM ALLOY (Al – Si) TERHADAP SIFAT MEKANIS DAN STRUKTUR MIKRO Ratih Ponco K.S., Erwin Siahaan dan Steven Darmawan Jurusan Teknik Mesin, Fakultas Teknik Universitas Tarumanagara Aluminum is one of type in material non-ferrous metals are frequently and widely used in fields of application in industry. One application that performed in the industrial world, namely Aluminum Silicon (AlSi) which are used for the motor piston components. To get better mechanical properties then the integration of Aluminum Silicon research done by arranging the variety of Si element content on a percentage of 6, 8, and 10% Si.Testing is done by using a blend of 10% genuine with further lowering the Si content to reach 6% and 8% by adding pure aluminum. The test showed that the level of harness decreased 12,5% and also the ability of toughness decreased by 4%. Observation show that the microstructure is relatively homogeneous and there is a dominant form of micro-structure of pure Al and several dendrites CuAl.

Abstract: Steel is an iron-carbon alloys containing concentrations of other alloys having a different composition and treatment materials, steel properties can be changed by heat treatment. The heat treatment process serves to increase the strength of a steel material. The nature of the material can be turned into a more robust and resilient heat treatment process, if done properly and correctly. Austempering process is just one example of the heat treatment process at steel that aims to improve the mechanical properties of the steel S 45 C and S 60 C. austempering process performed on the steel S 45 C and S 60 C aims to increase the hardness and toughness of the steel. Austempering process is done by austenisasi advance with temperature 8500C and held for 60 minutes, after which the process is carried out with 3 election austempering temperature of 3500C, 4500C, 5500C and held for 30 minutes. The method used to test the results of austempering is tensile testing using ASTM A370- 12a, Vickers hardness test and microstructure observation using a digital microscope. In the test results tensile steel S 45 C and S 60 C values obtained an increase in ductility and toughness of 17.1 % on steel S 45 C and 17 % on steel S 60 C. This value is obtained from the calculation of ultimate tensile strength test specimens that have not been in austempering process with a specimen that has been in the process of austempering at 3500C , and the results of testing hardness of the steel S 45 C and S 60 C obtained hardness value of 44% increase in steel S 45 C and 46 % on steel S 60 C. value this is obtained from the calculation of the average value of the test specimen is not in the process of austempering with a specimen that has been in the process of austempering at 3500C .

Abstract: Aluminum alloy is a raw material in industry. Aluminum alloy used is aluminum alloy aluminum alloy 319. Materials were investigated to obtain aluminum alloys that have strong mechanical properties of the difference in the rate of clotting. Research 319 aluminum alloy was investigated by conducting the smelting process in the crank case and printed materials by using metal molds, then do differences in rates of freezing process with an open-air media, media dry sand and wet sand media as a medium deceleration. The next step is testing using tensile testing, testing, hardness with Brinell method, and metallography. From the results, with the help of wet sand media has a hardness of 68 BHN and the UTS 241.89 MPa, for open air medium hardness of 62 BHN and the UTS 224.03 MPa and dry sand media assistance hardness of 54 BHN and the UTS 190.9 MPa.

Abstract: Lead (Pb) in solder has been used for decades in industries of electronic equipment. Mostly in the lead solder old electronic equipment containing 63% (Sn), 37% lead (Pb). Heating solder in high temperature steam generating heat which can damage the respiratory system. The purpose of this analytic is to obtain the characteristics of the mechanical properties of the alloy Sn-0,7Cu- "X" Zn better than the Sn-Pb alloy as an alternative to non-lead solder alloy material. Tests conducted in the form of density, melting temperature, metallography, shear strength, and hardness. The effect of addition of Zn alloy Sn-Cu-Zn increase hardness value of each acquired 85% of the material Sn-0,7Cu-10Zn, 81% were obtained from material Sn-0,7Cu-11Zn and 70% was obtained from material Sn -0,7Cu-11Zn. While the effect of adding Zn alloy Sn-Cu-Zn can increase the shear strength of each of about 29.4% on a material- 0,7Cu-10Zn Sn, 65% in material Sn-0,7Cu-11Zn and about 140% is obtained from material Sn-0,7Cu- 12Zn.

Abstract: Material developments in Indonesia is already very advanced rapidly certainly need high level of violence but has a mass of light. Aluminum should be developed because it possesses a lightweight and available in the land of our country that is rich in agricultural products. As an alternative to strengthen aluminum alloy that is with Si and Mg, as well as the rapid cooling process when smelting. This study was conducted to observe the microstructure and mechanical properties of the raw material of aluminum alloy series 6063. Tests conducted with metal mold, furan resin sand mold, commossa sand mold, the cooling rate of each mold will affect the hardness of the material which can be seen microstructure with microstructural observations. The survey results revealed that the aluminum with a metal mold casting has a hardness of 54 HRB, furan resin sand has a hardness of 40 HRB, sand commossa has a hardness of 33 HRB. Metal mold has a shock force of 0,316 J/mm2, particularly a furan resin sand shock force of 0,265 J/mm2, commossa sand has a shock force of 0.206 J/mm2. Metal mold has a high hardness compared with furan resin sand rated second, while the sand was rated commossa end but increasingly harsh mean tenacity of a material value will increase. According to the test micro structure, the aluminum is brittle, the distance or the distribution of grain will be a meeting or a lot.

Abstract: Warm water is needed by human being to take a bath, wash their clothes, their dishes etc. By the photothermal conversion, the solar energy can be used to heat the water. Flat solar collector is a tool which is used to capture energy of the sun radiation then convert it into heat to heat up water in collector’s pipes. The number of glass cover used effects the performance and efficiency of the collector. From this research, it is found that the efficiency of the collector is better when the cover used are two glasses than one glasses. The temperature difference of incoming and outgoing water in the collector using two glasses 15 ̊C higher than that of one glass.

Abstract: Solar energy, the renewable energy is only available at certain hour. So it is essential to develop efficient, economical solar thermal energy storage. Thermal energy storage (TES) systems provide several alternatives for efficient energy use and conservation. Phase change materials (PCMs) for TES are materials supplying thermal regulation at particular phase change temperatures by absorbing and emitting the heat of the medium. TES in general and PCMs in particular, absorb energy during the heating process as phase change takes place and release energy to the environment in the phase change range during a reverse cooling process. PCMs possesses the ability of latent thermal energy change their state with a certain temperature. Paraffin is the PCM used in this research. Paraffin is being added to a solar water heater to store thermal energy at daylight and supply the stored energy to the heat pipe when the sundown. From this research, it is found that the solar water heater with paraffin need longer heating time than the conventional solar water heater but it could provide steadier heating performance and warm water even when the sun was down.
