410km and 660km discontinuities are very clear and very easily identified discontinuities other than the Moho layer. This research utilizes SS precursor data, bouncepoints in the northern part of Sumatra. The data used is the depth of the epicenter <70 km, earthquake magnitude 5.5 and the distance between the epicenter and earthquake recording station more than 1000. This study is a preliminary study to determine changes in the depth of discontinuity in the study area. The SS phase is very well observed in the transversal component seismogram which is the result of the rotation of two horizontal components NS and EW, to obtain a good seismogram a 0.03Hz low pass filter is performed. In this study used 38 data transversal component seismograms, from 76 horizontal component seismograms. The most important thing in this study is the determination of the SS phase used as a reference (point 0), the SS phase is determined using the AK135 table guide, then the SS precursors are determined which can be seen at 450 seconds, 300 seconds, 90 seconds and 50 seconds before the SS . SS prekursors that are very clear at 450 seconds, are strongly suspected as a 660 km discontinuity. SS prekursors can be seen clearly after the stacking process.

The Final Disposal Site (TPA) of Batulayang Pontianak, West Kalimantan, uses an open dumping system so that it produces waste water (leachate). Its area on peatlands creates problems, especially in the distribution of leachate. The purpose of this study was to create a 3D model of leachate distribution in the soil layer in the TPA area of Pontianak Batulayang, West Kalimantan, based on the distribution of resistivity values. This study using the geoelectric resistivity method by the Wenner-Schlumberger configuration. The tracks that have been used are six, having a length of 117 m each. The results showed that the soil layer contaminated by leachate spreads from a depth of 5 m to 23.6 m. This layer is interpreted as sandy clay and sand, having a resistivity value of 0.152 Ωm to 13 Ωm. The results also showed that leachate comes from the West, North, and South directions, which spread to all study areas.

In this study, magnesium ferrite was sinthesized from natural iron sand using co-precipitation method. Iron sand material was taken from the north coast of Sarmi Regency, Papua Province. The purpose of this study was to find out whether magnesium ferrite could be synthesized from iron sand directly without preliminary processes into magnetite minerals. Co-precipitation method was applied with a variant of stirring temperature of 30, 50 and 70°C. The crystal structures was characterized using an x-ray diffractometer, while the magnetic properties was characterized using a vibrating sample magnetometer and the morphology of the particle was characterized using a scanning electron microscpe. From the results of characterization, it is known that magnesium ferrite successfully synthesized from iron sand directly without preliminary processes into magnetite minerals. Magnetic properties were obtained from the sample with added of magnesium acetate tetrahedral and stirred at a temperature of 70°C. The x-ray diffracttion pattern showed figure of merit of 0.82, while the magnetic hysterisis curve shows coercivity of 200 Oe and magnetic moment about 11 emu/gr. The mineral has irregular particle sizes that range from 0.5 to 100 microns in size, due to magnetic attraction which promotes agglomeration. This researcher recommends optimization of the synthesis process so that the quality of the magnesium ferrite can be improve.

The solution of the Dirac equation in the presence of the electromagnetic field on the one-dimensional barrier potential is studied. The energy spectrum and the eigenfunction of the Dirac equation obtained by solving the Dirac equation and we introduced annihilation and creation operators for the Hamiltonian has an identical form in the harmonic oscillator. Regions I and III separated by a potential barrier characterized by the gap energy with the eigenfunctions as a sinusoidal function, and region II has the form of an exponent function. We found the eigenfunction involved positive and negative energy moves exponentially when passed through a barrier.

Automation of three slit interference experiments has been carried out. The light interference is an interesting phenomenon to observe. The observation of the three-slit interference pattern uses a light sensor that is connected to the computer through the interface. Light intensity data will be directly recorded into the computer and displayed in the form of graphs of the light intensity versus time. To measure the pattern of the formed dark light, the light sensor is placed on a linear drive system. This drive system will move the sensor to the left or right to record the intensity of the pattern of dark light. The purposes of this study are: 1) designing an automatic experiment to observe three slit interference patterns and 2) measuring the wavelength of the light source, He-Ne laser, used in the experiment. From the experiment, we find that the wavelength of He-Ne laser is nm.

Noise decomposition on seismic volcanic data with wavelet using Daubechies wavelet decomposition on X and Y direction record data. Seismic volcanic data is in the form of broadband data, which broadband data has a wide frequency range so that it has a high enough noise level. So that when the noise decomposition process is carried out in selecting the decomposition of the noise it must be appropriate so that the information contained in it does not decompose, this is because the volcanic broadband seismic record data contains volcanic earthquake event information that has an amplitude at the same value as the amplitude of the noise. Therefore noise decomposition is done by implementing wavelet, that is by using Daubechies wavelet decomposition. The results show that Daubechies wavelet decomposition can break down noise properly without losing the information contained in the signal. The decomposition of noise uses Daubechies db 5 level 5 wavelet decomposition in detail. The results of the wavelet using wavelet decomposition obtained vulcanic earthquake events whose signal results showed conformity with volcanic earthquakes with T. Minakmi and wasserman's forms.

The textile industry is currently moving towards to the fourth Industrial Technological Revolution. One of the applications of the industrial revolution 4.0 is in the field of computational physics. The application of applied physics especially computational physics on textile science can be initiated in analyzing the quality of fabric in the textile coloring process. This research focuses on a technique measuring the quality of fabric that occurred in the coloring process using the image processing technique by measuring the color space in the RGB (Red, Green, Blue) space as the length of colors vector of the fabric. In this study, the technique has been made using MATLAB 2009a software and Logitech C525 HD webcam. The result of this research shows that computational physics especially image processing by MATLAB can be implemented to measure and to determine the color quality of fabric accurately by comparing with the samples.
