Abstract

Research to utilize natural polymers continues to be driven primarily by utilization as an environmental friendly energy-generating and storage material. The high porosity makes cellulose acetate (CA) a good candidate as a dielectric material as the basis of the supercapacitor device. Various dopants and compositions have been widely used, but the nano size morphological differences of the same material are rarely reported. Two types of ZnO are prepared, i.e., nanoparticles and nanorods deposited with CA and deposited on ITO glass substrate. The CA-ZnO / ITO composite film was fabricated through spin coating technique. This study focused on ZnO morphological difference on the microstructure and the dielectricity of CA-ZnO /ITO composite films. The morphology of nanoparticles and nanorods of ZnO were analyzed more detail with respect to its microstructure and dielectric properties. It is revealed that the change of ZnO morphology from nanoparticles to nanorod increase the capacitance and dielectric constant significantly from the order of the nano to the micro and decrease the dielectric loss. The dielectric constant of CA-ZnONP/ITO and CA-ZnONR/ITO are respectively of 2569 and 97159 at 100 Hz. The capacitance and dielectric loss of CA-ZnONP/ITO and CA-ZnONR/ITO reach to 69.809 nF; 678 and 2,15765 µF; 13,23 respectively.

Abstract

A study of mass measurement using strain gauge 120 which was placed in the corner of the brass cantilever has been done. This study essentially utilizes deflection phenomena on the surface. This phenomenon occurs due to the mass placed on one end of the brass cantilever. The Mass was calibrated with standard mass gauge using OHAUS PA214 PioneerTM analytical balance. It was done a variation of mass-reduction and addition at the end of the brass cantilever with a multiple of 0.1 gram over a span interval of 1.1-7.5 grams. It obtained hysteresis curve plot for the changing strain gauge resistance (ΔR) versus mass variations on which the system has the maximum load range (7,1-7,5 gram). Moreover,  The test of the system for the mass variations in the output voltage of the IC AD521JD differential amplifier was approximated as a quadratic function which was expressed in the system characteristic equation m = 2,4×V2 - 0,8533×V + 1,1449, with m (gram) and V (Volt). The characteristic equation is used in the ADC conversion of the microcontroller. The measured mass value was displayed on 2 × 16 LCDs in grams.

Abstract

Biogas is a gas produced by the decomposition of organic materials involving microorganisms in the anaerobic state. The research focused on obtaining good quality biogas through NaOH and KOH purification by reducing H2S and CO2 levels. The purification of biogass proceeded in a variation of absorbent concentrations 0,05M, 0,1M, 0,15M  NaOH and KOH solution.  Gas chromatography chose for biogas characterization. Based on TCD detector in gas chromatography, it represented concentration area in percentage (%). The content of biogas for control was 2.14% CO2 and 0% H2S. The Addition of 0.05; 0,1M; 0,15M NaOH produced  1,57%, 1,56% and 2,98% CO2 respectively. Moreover, the addition of 0.05 M; 0,1M; 0,15M KOH yielded 0.81%, 0,30% and 1,03% CO2. The highest of the burning calories was the NaOH 0,15M amount of 66,528 kcal and the lowest of the burning calories was the 0,1M KOH amount of 38,976 kcal.

Abstract

Electrical conductivity is one of the water quality parameters. The value of conductivity is an early indication of water pollution. Standard of the water conductivity value according to WHO should be less than 400 μS/cm. The prototype of the well-water conductivity sensor system consists of the power supply, temperature sensor circuit, conductivity sensor circuit, Arduino UNO microcontroller, 16x2 I2C LCD characters and the conversion equation.

Abstract

Northern Sumatera is one of Indonesian region that prone to earthquake. On the other hand, this region has a high level of vulnerability, because of large number of population and high economic growth rate. Thus seismic hazard analysis is needed to analyze earthquake hazard in this region. Probabilistic seismic hazard analysis being carried for count uncertainty factor, ie size, location, and frequency of the earthquake. This method consists of source identification, source characterization, attenuation function selection, and seismic hazard counting. After being calculated, the Northern Sumatera region has hazard value between 0.05 – 1.3 g. The region that has maximum hazard value is the group of islands in western Sumatera, and the minimum one is in the eastern coastline of Sumatera. Banda Aceh and Padang Sidempuan City have a medium level of earthquake hazard, with the most dominant source from Sumatera shear fault. Meulaboh and Gunung Sitoli City have a medium level of earthquake hazard, with the most dominant source from the subduction zone. Medan and Lhoksuemawe City have a low level of earthquake hazard, with the most dominant source from the deep and shallow background.

Abstract

Study on process design of benzene nitrification has been done. The activation energy (Ea) and frequency factor (k0) for this reaction were obtained from the literature. Calculation of physical and chemical properties was conducted automatically in HYSYS using NRTL and UNIQUAC Thermodynamic model. Several aspects of process design were investigated during simulation, i.e., the dependence of reaction conversion to temperature, the effect of sulfuric acid ratio against nitric acid in the synthesis of nitrobenzene in CSTR (Continuous Stirred Tank Reactor), and the effect of reactor series and parallel structure to reaction conversion. The highest conversion that can be achieved in single CSTR amounting to 96.9% at a ratio of sulfuric acid to nitric acid = 3.5, and temperature of 50 ºC. However, based on this study it is recommended that the most favorable condition for the nitration of benzene in an isothermal CSTR is 50 ºC operating temperature and a low ratio of sulfuric acid to nitric acid (i.e., 2.5 – 3).

Abstract

The photodegradation activity of MgFe2O4 nanoparticles for Hg waste has been successfully performed. The MgFe2O4nanoparticles have been synthesized by the coprecipitation method. The obtained sample was characterized for their microstructural properties by using X-ray diffraction. The results confirmed that the sample was polycrystalline and has a spinel crystal structure with space group Fd3m.  The size of the crystallite is about 29.4 ± 0.2 nm. The gap energy of the sample was calculated from the UV-Vis results (4.17 eV). Furthermore, the MgFe2O4 nanoparticles can be used as functional photocatalyst material for degradation of mercury (Hg) ions in wastewater.

Abstract

Mechanical stimuli have a significant influence on the growth of bone. Osteocytes of canaliculi can communicate with osteoblasts. Furthermore, osteoblasts communicate with cells in the bone marrow with projecting it cells into endothelial thus forms new bone cells. This aims of this research are to determine the effect of mechanical stimuli on the static and dynamic of stress, strain, and strain rate on the bone tissue and the influence of differences in bone properties (Young’s modulus). In this research, a linear elastic material model was chosen for bone tissue modelling and analysis. The strain and stress of the modelling bones were calculated using finite element method of the derivation harmonic oscillator for bone. The results showed that the static force results maximum strain rate  20.986/s, furthermore, due to the different properties of the bone (reduction is 6% of Young’s modulus of 17.9 GPa to 16.92 GPa ) resulted in the increase strain rate 0.238/s.The increase in external force is proportional to the increase in the maximum strain and strain rate. The decrease bone properties (reduction is 6% of Young’s modulus) decreases the tension 2.36%, raise the strain 14.536% or every decrease 2% (the increase is one decade of age) will decrease tension 0.78667% and the increase the strain 4.485%. The results of this study can be used to calculate the bone density by using the equations of  V. Klika and F. Marsik. Besides, this analyze study also useful for modelling the growth of bone around the joints in the spine.
