The use of biodiesel in boilers has great benefits because it reduces exhaust emissions. The purpose of this study is to test the quality of solar and biosolar raw materials as fuel from the boiler, analyze the concentration of pollutant gases (NOx, CO2, SO2) from the combustion of biosolar and diesel oil experimentally. The combustion system in the boiler tends to be simpler than compression ignition as is done with diesel engines. This research was conducted experimentally in a fire tube boiler, with a heat input rate of 60,000 kCal / hour and a pressure of 3 bar using biodiesel made from CPO (crude palm oil) as fuel. The mixture varies at 0, 5, 10, 15, 20 and 25% biodiesel in a mixture with biosolar diesel (B0, B5, B10, B15, B20 and B25). This research was carried out experimentally by testing the exhaust gas emissions generated from the stack gas stack which is expected to produce low exhaust emissions and are environmentally friendly. The results show that the use of biodiesel reduces gas emissions by increasing the value of biodiesel in the mixture. The results showed that the lowest gas emissions were around 4.142% (NOx); 12.50% (SO2) and 7.9% (CO2) contained in a mixture of 25% biodiesel in fuel (B25).

Abstract: Fuel entering through the main jet nozzle, affects engine performance and the composition of the exhaust gas is produced. Research the composition of the exhaust gases in machines otto one cylinder done with experimental method. The purpose of this study was to obtain the characteristics of the engine with exhaust gas analysis method. This research done with varying size main jet nozzle and varying the engine rotation every 400 rpm. Data processing the results of testing includes a comparison of the composition of the exhaust gases is HC, CO2, CO, O2, AFR, and the temperature of the exhaust gases. Then calculate the enthalpy of combustion for each main jet nozzle. The composition of the exhaust gases are best obtained from the main jet nozzle GX 160 which has the highest CO2 value of 20%, with the lowest CO value of 1.26% and the largest combustion enthalpy value with the value of 264.769 kJ. From the analysis can be known that the burning of the main jet nozzle GX 160 approaching the stoichiometric combustion.

In the activities of the Pratama Insinas, Ministry of Higher Education technology research in 2018, PTKRN BATAN built a testing facility that simulates a passive cooling system on the reactor core when there is a loss of outside power. The test facility is the Passive-02 System Simulation Facility (FASSIP02).In FASSIP-02 there are several parameters that need to be measured, one of which is temperature. In the measurement of temperature using a K type Thermocouple Connected to the National Instrument 9178 and 9213 modules that use computer programming with LabVIEW software. Temperature measurements need to be characterized.Characterization of type K thermocouples was carried out using thermobaths, 30 type K thermocouples, standard thermocouples,National Instrument modules 9178 and 9213 with computer programming displays using LabVIEW software. The method used for characterization oftype K thermocouples is a fixed temperature comparison method where the results of the temperature control of thermobath is 30-90 ͦC compared with the results of measurements from the type Kthermocouple and standard thermocouple. From the difference of the copper-wrapped junction tip thermocouple without the copper-wrapped and standard thermocouple produces a small error value, so the use of copper as a thermocouple junction end wrapper can be used as a temperature measurement FASSIP-02.

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.

Engine mounting is one of the car component which is has optimize function to obtain thesystem in the car is extremely perfect. The engine mounting has to be have behavior ductile by strongestenough to support the car engine whether in rest and moving position. To obtain car engine mountingwhich has these function it has to be treated by treatment. The method was used by using Heat TreatmentSystem which we were Hardening and Tempering. Heat treatment of engine mounting is needed toanalyze the microstructure and mechanical properties of low carbon steel used. Tests carried out attemperatures of 800oC, 850oC, 900oC and normal conditions without heat treatment. Then continued withimpact charpy testing, vickers hardness testing, microstructure observation using microscope and SEM.The tests are carried out in accordance with ASTM E23, ASTM E92, ASTM A370 standards. The Vickerstest results provide the lowest HV value of 118.7Hv at 900oC, while the normal condition is at 137.409Hv.The charpy impact test results give the lowest value of 0.06 j / mm2 under normal conditions, while at900oC at 0.0962 j / mm2. The results with microscopy and SEM, the greater the temperature given to heattreatment, the less pearlite will be, while the amount of ferrite and austenite increases which makes theengine mounting more toughness.

Abstract: Brass material widely used in industry because it has the advantage of being a metal that resists corrosion, has high ductility, good toughness and easy on the form. This study was conducted to determine the effect of rolling process on mechanical properties and microstructure of metal brass after ECAP process on brass (CuZn) 70/30. The initial step is to make the specimens with a diameter of 10 mm and height 80 mm has been done annealing 600 ° C with a hold time of 90 minutes. Then a ECAP 3-pass process and cold rolling process. To determine the mechanical properties of tensile test specimens and hardness test) and metallographic observations to determine the microstructure. The results after the execution of the research note that the specimen after passing through annealing process, ECAP and rolling have a higher hardness. Prior to treatment the specimen hardness value is 78 VHN and after treatment to 252 VHN hardness value. Metallographic observations of known properties of brass increasingly refined microstructure and grain boundary between micro become increasingly tight.

Abstract: Viscosity or viscosity is one of the quantities that are very important in the analysis of the behavior and movement of fluids that come into contact with other objects such as solids {solid body). Viscous dampers can be used to reduce the amplitude of the response due to the unbalanced mass, rotation critically, noise and shock loads. Absorbers working with fluid film bearing securities which are placed at a certain point, which is connected to the shaft-rotating rotor. Certain viscosity fluid will be forced to pass through a narrow slit with a certain pressure that can absorb the energy supplied by the shaft, this damping effects that can provide resistance to the rotor shaft system because the fluid has a linear damping and damping effect histeriktik. Viscous dampers can be used to reduce vibration amplitude response at a fixed price in accordance with the physical nature of the damper, the use of viscous dampers are widely used to control engine speed and turbine rotational speeds are like a helicopter rotor. From the test we can produce the damping effect on the engine rotation can reduce the response time domain vibration with an amplitude reduction of approximately 60% for the damping ratio ζ = 0.5.
