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.

Abstract

Characteristic I-V of Cu/Cu2O solar cells with belimbing wuluh (Averrhoa bilimbi l.) electrolyte have been determined using sun simulator data by varying the resistor value (R). The resistor of 1-10 kΩ was applied. The Cu2O layer as a p-type semiconductor is formed by thermal oxidation plate Cu at a temperature of 550 °C. The thermal oxidation time is 80, 100, 120 minutes. Sun simulator measurement result showed that the addition of thermal oxidation time improved the current (I) values, where the most improvement occurred in Cu/Cu2O-100. Furthermore, the current dropped with increasing voltage (V) indicating increase the resistor value. Optimal power (Pout) increases with increasing applied time the thermal oxidation of the Cu plate at 100 minutes. Plotting characteristic I-V give the efficiency (η) of solar cells from samples, and it was found that the Cu/Cu2O-100 reached the highest value, i.e., 2.84 %. In general, the more layers of Cu2O are formed, the higher the efficiency of solar cells.

Abstract

A Study on the development of an Testing Experiments model has been carried out which aims to improve the scientific abilities of students in the Physics Department. This study is motivated by the implementation of practicum that has almost no innovation, no change, always verifying patterned and less developing students' science process skills. The 4-D model RD approach was used to develop this practicum model. The instrument used is a handout that is equipped with a rubric as a practical guide and assessment guide. A total of 20 students were involved as research subjects. The results showed in general there was an increase in student scientific abilities. Of all the sub-abilities developed, the average percentage of achievement scores reached 60% in almost all sub-abilities after the 4th or 5th practicum or at the fourth or fifth week. However, there are sub-skills already reaching 60% in the 3rd practicum. Student and peer responses show that this practical model is better and more comprehensive in developing students' scientific abilities.
