The need for energy consumption nowadays becomes very important things, especially the need for electrical energy. Technology to convert heat into electricity directly can be realized using thermoelectric generators. To know the thermoelectric generator performance, this study performs an investigation of thermoelectric generator operated using motorcycle exhaust heat to generate DC power. Three identical thermoelectric generators model TE-MOD-5W5V-35S were used in this investigation. To generate different high temperatures the motorcycle was run at 1600 rpm, 2100 rpm, 3100 rpm. The circuits examined were series, parallel and combination of the two. All data were recorded using DAQ MX 9714 NI data logger that was connected to the PC using LabView program. The loads used in the current measurements were a thermoelectric cooler module model SP1848 and a fan 12 V - 0.13 A. Those two loads were installed in a parallel circuit. The results show that the tests without load produce the highest voltage, while the tests with the load result in the highest power. Increasing the temperature difference increases the power, and the parallel circuit results in the biggest power but the lowest voltage. The highest voltage of 3.3 V with series circuit was attained, and the highest power of 0.133 W with a parallel circuit was also obtained.

The ducted tidal turbine models have been developed to utilize convertion of the kinetic energy on ocean currents. The research on refining the turbine characteristics has been carried out by modifying the turbine’s shape and size. The study of the duct diameter ratio effect on the energy characteristics of the turbine was done in this work. This study was conducted by modifying the duct diameter ratio () with the constant inlet diameter D0 and outlet D2. The flow conditions are analyzed for five cases of turbines with different shapes and diameters to determine the optimum conditions. The optimum value of the diameter ratio could be obtained at the maximum value of power coefficient CP. Flow velocity in the ducted turbine was measured at three turbine sections, namely; the inlet section, the impeller housing section, and the outlet section. The measurement of flow in turbines was carried out at the free stream velocity U0 = 1,5 m/s. The power coefficient CP and thrust coefficient CT were calculated based on flow velocity data on the turbine cVennell sections for each case. The power coefficient CP reaches the maximum value (Betz limit) at the resistance coefficient K = 2 and the value of axial induction factor a = 0,37. These values were founded at diameter ratio d=0,66. The value of thrust coefficient CT reaches the maximum value at K = 3,9, a = 0,53 and . The optimum value of the diameter ratio was founded at d=0,69.

This research was conducted on white cast iron (Ni-Hard 4) and medium carbon steel (S45C) cast iron materials using a thin brass plate (CuZn 35) 0.3 mm as filler metal by heating at temperatures of 850 to 1050 0C for 120 minutes with a pressure of 2 Mpa in the muffle furnace. The effect of temperature on the microstructure was observed using an optical microscope and scanning electron microscopy equipped with energy dispersive X-ray system (EDS) to determine the chemical composition that occurred between the three meterial layers. The thickness of the interface layer increases with increasing holding temperature. The highest shear strength (79.86 Mpa) was obtained at a temperature of 950 0C.

The dynamic behaviour of the vibration system in the experimental analysis is observed from the response to the stimulus acting on it. In this case, the relationship between the stimulus at a certain location and direction is specifically related to its response respectively. The relationship between stimulus and response is called the Frequency Response Function (FRF) or better known as the transfer function. In measuring the transfer function, the stimulus to the structure is given in the form of an excitation force while the vibration response measurement depends on the type of sensor or transducer used. Diverging from the above problems, vibration testing is carried out on a structural model. This test uses an Aluminum beam as a specimen by using an excitation signal that comes from an exciter and an impact hammer. This research aims to examine the dynamic response in the form of vibration characteristics response in the frequency spectrum of an Aluminum beam. Based on this spectrum maps, we can observe the dominant frequency (a frequency with large amplitude). Furthermore, from these frequency data, it is expected to determine which frequency components are derived from component element defects and indications of resonance frequencies on machine elements or noise originating frequencies.

The landing gear is one crucial component in an Unmanned Aerial Vehicle (UAV) aircraft construction. Landing gear serves as the main supporting component of aircraft load when landing and take off. This research aims to investigate the fatigue design life of the main landing gear on the UAV aircraft. The main landing gear frame design used Autodesk Inventor Professional 2017, while finite element analysis used Ansys Workbench software. It is subjected to a load of 1500 N with a loading fully-reserved. The prediction for fatigue life using Gerber mean stress theory. The material of the main landing gear frame is Aluminum alloy 6061. The simulation results show that the main landing gear frame has a minimum fatigue life of up to 3.5 x 107 cycles with a minimum safety factor of 1.43.

Motor vehicle emissions have proven lead to environmental and human health quality degradation. Therefore, efforts to reduce emissions especially motorcycles need to be done. Utilization of carbide waste has been proposed to be one of the solutions to reduce the level of emission of motorcycles. The carbide waste used is formed into granules and then installed into a reactor and placed in the exhaust line which will act as an adsorbent. The experimental study was conducted experimentally using a Yamaha Mio M3 125 CC. The results showed a reduction in exhaust emissions when using carbide waste adsorbents compared to emissions without adsorbents. The reduction was even greater when the volume of carbide waste was also greater. The reduction occurs in all types of emissions, both HC, CO, and CO2. It was obtained a reduction in emissions could reach up to 57 % for HC. However, the reduction performance cannot last long because the adsorbent has been saturated. Therefore further research is required to be performed.

Now ULH-related research has become a trend among researchers in hydroelectric power. One form of ULH can be water in pipe. Meanwhile, utilization of horizontal channels as power plants is still low, because the yields obtained are not large enough. Utilization of ULH horizontal flow can be an interesting topic for renewable energy at pico scale, where the reaction turbine that is suitable in this case is propeller turbine. The advantages of propeller turbines are practical, high efficiency, simple, and low production costs. Propeller rotors used in this study had a diameter of 83 mm and a blade inclination of 25°. This study uses addition of a static bulb body to increase the speed of fluid flow, ratio of static bulb used in this study is 0.6. Discharge used is varied from 7 l/s, 9 l/s, 11 l/s, and 13 l/s. This study aims to determine the effect of inlet hub angle blade of turbine performance on horizontal flow in pipe. The highest results on use of the largest discharge are 33° inlet hub angle which produces 17.2 watts at 1283 RPM shaft rotation, and the coefficient of performance (CP) obtained reaches 54%. However increasing the value of the inlet angle of blade hub does not linearly increase the value of mechanical power. The blade with an inlet angle of 44° has the smallest performance, the mechanical power generated is only 13.9 watts at 1045 RPM.
