Abstract

Bamboo is a natural material that is widely found in South Banten. Using bamboo as an alternative material for manufacturing brake pads is interesting to research. Bamboo resistance to attacks of organisms is so low that it is necessary to give initial treatment. Preservation of bamboo sticks is done by soaking them in seawater. This immersion is determined for 15 and 30 days. The comparison of the composite constituent composition is 30% bamboo fiber, 28% bamboo particles, 2% zinc, and 40% epoxy resin. Compaction pressure is carried out by 400 kg/cm2 for 10 minutes. The sintering process is carried out at a temperature of 150 °C for 60 minutes. From this research, it is known that the immersion of bamboo stems in seawater tends to decrease the hardness and the wear rate of composites.

Abstract

Renewable fuels hold the key to the increasing energy demand and environmental issues. In recent years, the installed capacity of renewable energy sources has experienced rapid growth based on limited remaining oil reserves. Applying hydrogen/oxygen as fuel in combustion engines is possible. Hydrogen (H2) which burns with Oxygen (O2) in the combustion chamber, will produce H2O compounds that are environmentally friendly. In this study, we wanted to see the effect of increasing the voltage of the interface bipolar plate to increase the H2 and O2 gas molecules volume. The experimental results show that the breaking of bonds in water compounds which utilize the interaction force between fields and charges, has been affected by an increase in voltage. The time to convert the H2O compound into H2/O2 gas molecules decreases with the increasing voltage between interfacing electrodes. The voltage increase affects the Volumetric Flow Rate (VFR) of H2 dan O2 gas molecules. This study also shows that when a voltage of 10 Volts is applied at the electrode interface, charge transport occurs optimally.

Abstract

Magnetic particles have been used for hyperthermia by inserting ferromagnetic material into tumor tissue. La(1-x)Sr(x)MnO3 is one of the best candidates for hyperthermia due to higher magnetic at ambient temperature and their Curie temperature easily adjusted. This research synthesized La(1-x)Sr(x)MnO3 using the ball milling technique. Several heat treatments were also conducted after ball milling processing. Various investigations, including SEM-EDS, XRD, DSC, and VSM, were conducted. LaMnO3 has a hexagonal structure, which has the space group R -3 c. From the diffraction pattern seen in LaMnO3 and La0.9Sr0.1MnO3 seen at angles 32.376 and 32.706, it looks separate like the database diffraction pattern. In La0.9Sr0.1MnO3, these two peaks are seen to be increasingly separated. In contrast to the diffraction patterns of La0.7Sr0.3MnO3 and La0.5Sr0.5MnO3 at an angle of 32.376, there is a decrease in intensity. The specific heat capacity of the alloy with Sr substitution of 0.3 has a greater value than that without substitution and the lowest occurs in the alloy with Sr substitution of 0.1. The magnetization value for Sr substitution is 0.3 higher than for other alloys.
