Published: July 2020

Abstract

Tuberculosis is a disease caused by a bacterium called Mycobacterium Tuberculosis. Most Tuberculosis bacteria not only attack the lungs, but also attack other organs. Tuberculosis disease can spread and contaminate through the salivary and bacterial when the sufferer coughs and sneezes. Thus, the contagion of tuberculosis can take place either through contact directly with the sufferer or through the air. The examination system of Tuberculosis is still done manually. Therefore, a computational method is necessary to examine and identify Tuberculosis suffered by the patient through X-ray images of human lungs. The method used in this research is the Extreme Learning Machine. Lung X-ray images are used as input for image processing. The steps taken before identification were image pre- processing and Thresholding. The external results of this research include HKI in the form of software (registered), international conference presenter (done). In addition, the results of this study can assist public in determining the types of tuberculosis suffered so that it will be more efficient in early treatment of the disease.

Published: July 2020

Abstract
This research concerns on the influence of higher order solution to nonlinear evolution of bichromatic waves based on Benjamin Bona Mahony (BBM) equation. Asymptotic method was applied to determine the solution expanded to the fifth order. In previous researches, this method was applied on the same equation to find its solution up to the third order and it was obtained that the waves underwent deformation and amplitude amplification affected by the occurrence of a pair of side bands during their propagation. In this study, the effect of the higher order solution on the increasing amplitude was observed. A quantity called as Maximal Temporal Amplitude (MTA) was measured to find the maximum position where the highest amplitude occurred and the Amplitude Amplification Factor (AAF). MTA gives information about the waves’ highest elevation at every spatial position during the observation time. The analysis includes comparison between the third and fifth order solutions in their contribution to the rise of the amplitude and the maximum position.

Abstract
Labuhanbatu Regency is a regency located in the North Sumatra province of Indonesia. This regency is crossed by a national road across Sumatra that connects provinces on the island of Sumatra. This has led to an increase in traffic accidents in this region. The number of accidents reached 114 accidents in the official police report for 2018. This study discusses locations that have a high frequency of accidents and represents them in the form of spatial data. The data used is based on the official report of the accident from Labuhanbatu Resort Police in 2018 which consists of 3 attributes namely, accident id, time of the accident, and location of the accident. The method used is to create a density map to calculate complexity in certain areas using Quantum GIS. This study uses the Kernel Density Estimation (KDE) method with a search bandwidth in an area of 300 meters. The results of the study are accident heat maps for the study area and related to the inputted attributes. The highest heatmap in the Bilah Hilir and Panai Tengah sub-districts with 25 attributes and 24 accidents included. The use of heatmap can produce spatial data that is easier to understand because it’s clustering from the same area. In this study, clustering is done based on the time of occurrence to obtain a heat map in red to black for the density level based on the frequency of accidents.

Abstract
Indonesia is one of the countries with high plant diversity. Almost every region in Indonesia has distinctive plants and may not be present in other countries. Based on these facts required a strategic step to record and identify plants in Indonesia. One method that can be used to leaf image feature extraction is the Gray Level Co-occurrence Matrix (GLCM). This research will implement k-Nearest Neighbor (k-NN) method to classify type of plants based on leaf texture. The classification result based on GLCM using k-NN classifier showed that the accuracy using k = 3 was 83%. The use of parameter k influence classification results, the greater the value of k then the accuracy would be smaller. Classification errors for some types of leaf images occurred because the value extraction traits generated by GLCM was very similar and had a small range of values.

Published: July 2020

Abstract
The current modern smartphones have been equipped with multiple sensors to add the functionality of the phones. Two of the most significant sensors, accelerometer and gyroscope, are intended to sense the movement and orientation of the phone. We performed research to evaluate the capability of these two sensors to detect a road’s quality, which can be used to generate a map of road quality in a certain area. The research is done by placing the mobile phone in a flat area inside the car and ride the car through roads with various quality, especially the damaged ones. We collected the value of both sensors when passing through hollow, bumpy, and cracked roads with several variations of speed. Based on our test, we conclude that this method is not effective in detecting the quality of the road since it is hard to differentiate the data from other behaviours such as accelerating, braking, turning, or even the car vibration. In this paper, we present the method used to perform this research and the collected data that may help our conclusion.

Abstract
We present a client-server based smartphone application that act as a music input device with several outputs. The application allows user to interact with one phone as the input and the server and hear the sound from several connected smartphones that act as clients. Since transmitting data may require some time, we need to deal with transmission delay. Hence, we developed an algorithm to detect the delay and synchronize these values between all connected devices. By agreeing to a single delay value, we were able to minimize the difference in playtime between server and connected clients. We performed the test by building an Android-based smartphone application, installing it to multiple devices, and connecting them to a WiFi-based local area network. The test shows that our proposed system has successfully reduce the difference between devices and the connected devices were able to produce sounds with insignificant delay.

Published: July 2020

Abstract
In this paper, we propose a method to represent a new method to represent large-scale 3D terrain efficiently to be used in a client-server collaborative terrain editor. The objective is to design a terrain representation that allows changes to be distributed between connected clients without throttling the bandwidth. The method divides the terrain into smaller patches so it can be streamed partially to connected clients. Moreover, we also reduce the data representation by using 8-bit values and modify the terrain representation to decrease the inaccuracy caused by data reduction. We present a thorough description of the proposed method and a demonstration of the technique in a practical collaborative 3D terrain editor application. We performed several tests with different terrain specifications and measured the interactivity level of the application. Based on these tests, we can conclude that the proposed method is capable of reducing the time-to-interactive of the application and consequently increasing the interactivity level of the system.

Authors: Prayitno T B , Budi E 
Published: July 2020

Abstract
We considered the effect of the electric field on the spin stiffness in the zigzag graphene nanoribbon by means of first-principles calculation. To reach the intention, a fixed planar spiral structure was formed together with a spin constraint method in the antiferromagnetic edge states of the zigzag graphene nanoribbon. The spin stiffness was then obtained by fitting the total energy difference in a set of spiral vector via the Heisenberg model. We showed that the trend of the spin stiffness changes as the electric field increases up to certain value. This means that the electric field can control the spin stiffness in the zigzag graphene nanoribbon.

AbstractOne of the solutions for fossil fuel crisis is to find alternative energy based on renewable materials. In this research, catalytic cracking of used cooking oil has been investigated to produce biofuel using Cr-charcoal catalyst. The charcoal was produced from solid waste (shell) of palm oil industry. Chromium solutions with various concentrations (1%, 2%, and 3%) were impregnated into charcoal to produce Cr-charcoal catalyst. The catalysts were used for catalytic cracking of used cooking oil at three levels of temperature: 450°C, 500°C and 550°C. The XRD patterns and SEM images of the catalyst showed that the catalyst was in amorphous form. SEM-EDX analysis showed that the Chromium was impregnated into charcoal successfully with amount of Chromium absorbed into charcoal was 0.51%; 1.07% and 14.38% respectively. The SEM images also showed that charcoal as supported catalyst and Cr-charcoal catalyst have unique pores. The highest liquid oil fraction was obtained by catalytic cracking at 500°C using 3% Cr-Charcoal catalyst. The liquid product of this process was mainly diesel oil with 8-24 carbon atoms (86.35%) and the rest was liquid product with 6-7 carbon atoms.
