Abstract

Malaria is a serious global health problem. Calculation of normal and malaria-infected red blood cells is manually calculated on image of the blood taken by the light microscope. The calculation of the normal and the malaria-infected red blood cells is to know the percentage of parasites and their growth. In addition, it was used to determine the percentage of inhibition parasite growth. The aim of this study is to automatically calculate a total, normal and malariainfected red blood cells. The steps for the calculation of the total of red blood cells: normalization, thresholding, separation and calculation of the red blood cells by labeling. The steps of calculation of malaria-infected red blood cells: converting RGB image to grayscale and to binary image, sweeping, and the calculation of malaria-infected red blood cells. The normal red blood cells can be determined by subtracting the total of the red blood cells with the malaria-infected red blood cells. This software is able to automatically calculate the total, normal and malaria-infected red blood cells. The results of automated calculation with the developed software are not different from a manual calculation. The calculation error of the program compared to the manual calculation is only one or two of the red blood cells for eachimage.Keywords: malaria, calculation of blood cell, infected blood cell.

Abstract

Impacts of climate change marked by the increasing emissions of CO2 in the air and increased precipitation make various parties began to feel the need to measure the gas content on a regular basis.These gases gradually accumulating in Earth's atmospheric layers. However, the desire was constrainedby a number of issues which then affect the accuracy of the continuous mapping circulating gas in theatmosphere. Researchers speculate that the amount of CO2 and other gases is growing each day due tothe many additional human-produced carbon emissions from burning fossil fuels. The results obtained bythe pattern of variability in Semarang rising CO2 and rising precipitation trends show an indication ofclimate change has occurred. It was proven occurrence of climate anomalies and the previous year.Keywords: CO2 variability, Rainfall Semarang

Abstract

Ising model or the Spin Glass is a model used to solve the magnetic properties of materials and the occurrence of phase transitions from paramagnetic to ferromagnetic properties. Magnetization of the material comes from the vortex that has two kinds of electron spin, ie {-1 / 2, +1 / 2}. Both spin gives the direction of magnetization (North-South) that opposite. Two-dimensional Ising model (2D), often called a Markov Random Field (MRF). This model is a stochastic model that can represent the image texture. Result binary image generation MRF much affected by changes in temperature, the spin direction will be random if the environment inside a high enough temperature, ie above the critical tempertaur (or Currie temperature) Tc, at this kedaan paramagnetic material. Conversely, if the environmental temperature below Tc, then the material would be ferromagnetic. As for binary image restoration MRF is affected by noise levels and the number of iterations, the best results the image restoration process at the level of noise from 0 to 0.5.   Keywords:  image restoration, markov random field, stochastic

Abstract

Computed Tomography (CT scan) is one of the X-ray modalities used in radiodiagnostic, as result it needs to do Quality Control (QC). This study focused on the image quality test of CT Scan by considering the spatial resolution parameters and using calculation method of the digital image. The effect of exposure factors (voltage and electric current) was also on image quality. This study using multislice CT (MSCT) 128 slice and AAPM CT Performance Phantom. Phantom scanned with the variation of exposure factors (80, 100, 120 kV and 50, 100, 150, 200, 250, 300, 350, 400, 450, 500 mA). The determination of spatial resolution value derived from the value of Full Width at Half Maximum (FWHM) of the Line Spread Function (LSF) and Point Spread Function (PSF) graphics. Results shown that the higher voltage applied, the smaller value of FWHM which show better image quality. This method is able to detect spatial resolution up to the 5th level (hole diameter 0.75 mm), whereas it is only up to 3rd level (1.25 mm) visually. The image quality in this study has been compared with the rules of West Austr Compliance Testing Protocol 2006, and it is proved that the  image quality is still good, thus the CT Scanner is still feasible to  use.

Abstract

The effect of gain to The Width at Half Maximum (FWHM) and Full Width at Tenth Maximum (FWTM) on B-mode image ultrasonogram (USG) has been investigated. The aim of this research is to determine the effect of gain on the spatial resolution according the measurements of FWHM and FWTM. The evaluated resolution type is axial and lateral. This research used phantom multipurpose multi tissue with gain (30 dB, 35 dB, 40 dB, 45 dB, 50 dB, 55 dB and 60 dB) on frequency variation source 6,2 Mhz, 8 MHz dan 10MHz. The axial and lateral resolution images were obtained by using USG which uses B-Mode imaging. The measurement was made by using digital image and calculated objectively with MATLAB. The measurement of FWHM and FWTM was obtained from IP-PSF analysis (In Plane-Point Spread Function) using approximation for the Gaussian function. The result shows that there is influence from gain on FWHM and FWTM. The decreasing gain resulted in decreasing of FWHM and FWTM. The decreasing of FWHM and FWTM represents better spatial resolution, and vice versa. Keywords: FWHM, Gain, Point Spread Function, Spatial resolution, USG,

Abstract

A study to identify focus on a digital microscope has been done using a threshold value of the object microscope image obtained by Otsu method. Microscope image of the object captured by the change from a maximum to a minimum distance between the object and the microscope objective lens to record the amount of movement of a motor stepper and calculates the Otsu threshold value on each image. Based on data from a Otsu threshold value of each microscope image of the object to the changes within the object can be inferred the existence of a relationship between the position of an object to focus the microscope with the image of the threshold value that is increasingly the focus of an image , the image of the Otsu threshold values ​​obtained are also getting smaller. In this study done by testing two samples as objects of microscope that single hair samples and samples collection of several hairs were each placed on a microscope glass slide. Data collection and observation results show that for a single hair samples obtained object focus Otsu threshold value T = 97 and sample an object consisting of a collection of some of the hair is obtained Otsu threshold value T = 127. But the testing of two samples showed differences influenced by the ratio between the number of pixels on the image and the background image of an object caused by the influence of the intensity of the light source of the microscope.

Abstract

In  this  study,  the  ESP32  microcontroller  and  the  Raspberry  Pi  have  been  successfully combined  to  adjust  the  position  of  the  digital  microscope  object  and  take  images  using  an android smartphone-based application via a WiFi network. The working method of adjusting the position of the microscope object is done by using the number of steps on a unipolar stepper motor  starting  from  the  farthest  distance  to  the  digital  microscope  objective  lens  which  is regulated by the ESP 32 microcontroller. Meanwhile, viewing the microscope object directly can  be  done  via  a  mobile  screen  connected  to  a  WiFi  network  to  a  digital  microscope  USB camera that has been converted into an IP camera by the Raspberry Pi. Therefore, through the use of a digital microscope application with an Android smartphone, it will be easier to obtain a sample image of a digital microscope object when conducting experiments in the laboratory.Keywords: Digital Microscope, Android Smartphone, WiFi, Rsabperry Pi, Microcontroller ESP 32
