Throughput Maximization Based on User Association in Heterogeneous Networks 异构网络中基于用户关联的吞吐量最大化
Khalid Sheikhidris Mohamed, M. Y. Alias, M. Roslee, Mohammed Jaber Alam
Cellular networks' endurance limitations are in constant abatement as extra numbers of cellular phone users are persistently occupying the resources of the network. Consequently, network resources, signal quality, Quality of Service (QoS) requirements etc. undergo hazardous conditions. Moreover, edge users are also endangered as they experience poor signal quality due to large separation distance and obstacles. However, smaller cells were introduced to alleviate the burdens from networks and explicitly comfort users. This paper, studies the Femto-cells performance over cellular networks and further proposes a user association scheme to off-load users to the Femto-cells. The simulation results reflect the outstanding performance of Femto-cells capabilities and how deploying 5 Femto-cells can relatively add-up 3Mbps to each user's throughput and approximately 10Mbps in a single iteration.
随着移动电话用户数量的增加持续占用网络资源,蜂窝网络的耐久性限制正在不断减弱。因此,网络资源、信号质量、服务质量(QoS)要求等都处于危险状态。此外,由于分离距离大、障碍物多,边缘用户的信号质量较差,也会受到威胁。然而,引入较小的单元是为了减轻网络的负担,并明确地安慰用户。本文研究了femto -cell在蜂窝网络中的性能,并进一步提出了一种用户关联方案,将用户卸载到femto -cell上。仿真结果反映了femto -cell功能的卓越性能,以及部署5个femto -cell如何使每个用户的吞吐量相对增加3Mbps,并且在单次迭代中增加约10Mbps。

Finding Pattern in Dynamic Network Analysis 动态网络分析中的模式发现
A. Alamsyah, Made Kevin Bratawisnu, Puput Hari Sanjani
Internet and social media changes the way human act and make social interaction daily. The accumulated of human social interaction form large scale unstructured data that possibly store timely knowledge. Social Network Analysis (SNA) methodology can be used to perform knowledge extraction from those unstructured data. SNA also provide the way to model user interaction pattern in social media. The majority research regarding user interaction pattern is in the form of static model, but in real-world, the interaction dynamically evolves. Hence, we use Dynamic Network Analysis (DNA) to study network dynamic structure during the observation time. In this research, we present analysis of user interactions evolution on social media, specifically in Twitter. As case study, Indonesia e-commerce and the telecommunication businesses are used for the reason of both are having high dynamic interactions market. User interactions is modeled as networks that are annotated with the time markers. Our finding is there are difference network properties during weekday and weekend, thus provide promotion pattern opportunity. The result allows us to understand the network properties phenomenon over the time, that leads to actionable effort such as when the exact time to do product promotion for business organization.
互联网和社交媒体改变了人类的行为方式,每天都在进行社交互动。人类社会互动的积累形成了大规模的非结构化数据,可能存储了及时的知识。社会网络分析(Social Network Analysis, SNA)方法可以用于从这些非结构化数据中进行知识提取。SNA还为社交媒体中用户交互模式的建模提供了途径。大多数关于用户交互模式的研究都是以静态模型的形式进行的,但在现实世界中,交互是动态发展的。因此,我们使用动态网络分析(DNA)来研究观测时间内的网络动态结构。在这项研究中,我们对社交媒体上的用户交互演变进行了分析,特别是在Twitter上。作为案例研究,由于印尼电子商务和电信业务都是具有高度动态互动的市场。用户交互被建模为带有时间标记的网络。我们发现工作日和周末的网络属性存在差异,从而提供了推广模式的机会。该结果使我们能够了解网络属性现象随着时间的推移,从而导致可操作的努力,例如什么时候为商业组织做产品推广。

Sukarno Sono, Nl. Meilani, T. Prihyugiarto, Y. Karyanti
There is a change in the technique or method of collecting and processing data on the Performance Monitoring Accountability (PMA) 2020 Survey by the National Population and Family Planning Indonesia, from a paper-based system to electronic-based which paperless system, one of the tools called Open Data Kit. This study was therefore aimed at identifying the users' perception and attitude towards the application of the new technology in this survey in Indonesia. One of the methods to determine the extent to which the users' acceptance of the application of a new technology is to use the Technology Acceptance Model. Data analysis was performed using the Structural equation Modelling with Analysis of Moment Structure software. The analysis results prove that out of six hypotheses, only one hypothesis is rejected. The results suggest that the application of a new technology system is acceptable and has no resistance from the supervisors and enumerators as the of smartphone-based surveys users. In conclusion, this technology is possible to apply in other surveys in Indonesia.
印度尼西亚国家人口和计划生育局在收集和处理2020年绩效监测问责制(PMA)调查数据的技术或方法发生了变化,从基于纸张的系统转变为基于电子的无纸化系统,其中一种工具被称为开放数据工具包。因此,这项研究的目的是确定在印度尼西亚进行的这项调查中用户对新技术应用的看法和态度。确定用户对新技术应用的接受程度的方法之一是使用技术接受模型。采用结构方程建模和弯矩结构分析软件进行数据分析。分析结果证明,在六个假设中,只有一个假设被拒绝。结果表明,新技术系统的应用是可以接受的,并且没有受到作为智能手机调查用户的监督员和普查员的抵制。总之,这项技术可以应用于印度尼西亚的其他调查。

Computational Analysis on Rise and Fall of Indonesian Vocabulary During a Period of Time 一段时间内印尼语词汇兴衰的计算分析
F. Rahutomo, R. A. Asmara, Deddy Kusbianto Purwoko Aji
Indonesian vocabularies are listed in Indonesian dictionary. The dictionary is published by Language Development Council, the Ministry of Education and Culture, Republic of Indonesia. Strangely, Indonesian citizen no longer uses many of Indonesian vocabularies which are listed in the dictionary. In contrary, the citizen uses so many new vocabularies which are not listed in the dictionary. The purpose of this study is to examine this phenomenon more deeply from computer science point of view. A collection of 6 months Indonesian online news corpus consists of 153,349 articles was used. Then the corpus was compared with 51,029 lemmas in Indonesian Thesaurus Dictionary. The analysis was done per day and per online media. This study reports 26,887 lemmas which never been used with daily increase trend during the period. While with 1,000 times appearance threshold, 509 new lemmas appear with daily decreased trend.
印尼语词汇收录在印尼语词典中。该词典由印度尼西亚共和国教育和文化部语言发展委员会出版。奇怪的是,印尼公民不再使用字典中列出的许多印尼语词汇。相反,市民使用了很多字典里没有的新词汇。本研究的目的是从计算机科学的角度更深入地考察这一现象。使用6个月印尼语在线新闻语料库,共153349篇文章。然后将该语料库与《印尼语同义词词典》中的51,029个词进行比较。该分析是每天和每个在线媒体进行的。本研究报告了26,887个未被使用的引理,在此期间有逐日增加的趋势。当出现阈值为1000倍时,出现509个新词,且呈逐日递减趋势。

Fast UART and SPI Protocol for Scalable IoT Platform 用于可扩展物联网平台的快速UART和SPI协议
Rizka Reza Pahlevi, Aji Gautama Putrada S, M. Abdurohman
This paper proposes the enhancement of Universal Asynchronous Transmitter Receiver (UART) and Serial Peripheral Interface (SPI) protocols for improving the node performance in the Internet of Things (IoT) platform. Implementation of UART communication protocol on IoT in microcontroller ATmega328 has limitation of Serial Hardware scalability so it must do bit banging which can affect performance and lack of speed. SPI requires change of SPI Control Register (SPICR) to become Slave Select which can affect speed and also have limited of Slave Select. There are many previous methods that have been proposed to solve this problem. However, none of them are scalable and speed aware. This proposed method uses parallelism concepts by implementing hardware environment. Through some experiments, this research succeeded to implement UART on FPGA where the speed is 67,3% faster than the microcontroller ATmega328 and is able to reach four UARTs. SPI Slave on FPGA has speed up to 73.43% faster than the microcontroller ATmega328 and is able to expand to two SPI Slaves.
本文提出了通用异步发送接收器(UART)和串行外设接口(SPI)协议的增强,以提高物联网(IoT)平台中的节点性能。在微控制器ATmega328中实现物联网上的UART通信协议具有串行硬件可扩展性的限制,因此它必须进行比特撞击,这可能会影响性能和缺乏速度。SPI需要改变SPI控制寄存器(SPICR)成为Slave Select,这可能会影响速度并且也有限制Slave Select。以前已经提出了许多方法来解决这个问题。然而,它们都不具有可扩展性和速度意识。该方法通过实现硬件环境,利用并行概念。通过一些实验,本研究成功地在FPGA上实现了UART,其速度比微控制器ATmega328快67.3%,可以达到4个UART。FPGA上的SPI Slave的速度比微控制器ATmega328快73.43%,并且能够扩展到两个SPI Slave。

Artificial Neural Network for Predicting Indonesia Stock Exchange Composite Using Macroeconomic Variables 利用宏观经济变量预测印尼证券交易所综合指数的人工神经网络
A. Alamsyah, Asri Nurfathi Zahir
Stock is a high risk and high return investment. The risk-comparison scale for both losses and profits are not much different. The lure of profits temptations can be given by playing shares, sometimes make people less cautious and eventually fail to invest in stocks. To make right and profitable investment decisions, investors need to face uncertainty and fluctuating stock price movements. These phenomena cause investors to predict stock price movements for minimizing risks. The purpose of this study is to predict the Indonesian composite stock price index by using macroeconomic variables as a reflection of economic condition and as a good signal to forecast stock prices. This research is using Inflation, Interest Rates, and Exchange Rates as the macroeconomic variables. This study uses secondary data from Bank Indonesia and Indonesian Statistics Center from December 2005 to November 2017. The prediction uses Artificial Neural Network (ANN) Backpropagation method. The results gained the accuracy of 96,38% and mean-squared error of 0.0046 with the best time delay of 2 months before the predicted month. Based on the accuracy level and the error, macroeconomic variables (exchange rate, interest rate, inflation rate, and money supply M2) are the proper indicator to predict IDX Composite movement.
股票是一种高风险、高回报的投资。损失和利润的风险比较规模并没有太大的不同。通过炒股可以获得利润的诱惑,有时会让人们变得不那么谨慎,最终导致投资股票失败。为了做出正确和有利可图的投资决策,投资者需要面对不确定性和波动的股价走势。这些现象导致投资者预测股价走势,以尽量减少风险。本研究的目的是利用宏观经济变量作为经济状况的反映,并作为预测股价的良好信号来预测印尼综合股价指数。本研究采用通货膨胀、利率和汇率作为宏观经济变量。本研究使用印度尼西亚银行和印度尼西亚统计中心2005年12月至2017年11月的二手数据。预测采用人工神经网络(ANN)反向传播方法。结果准确率为96.38%,均方误差为0.0046,最佳时间延迟为预测月份前2个月。基于准确度水平和误差,宏观经济变量(汇率、利率、通货膨胀率和货币供应量M2)是预测IDX综合走势的适当指标。

TCP Congestion Window Analysis of Twitter with Exponential Model 基于指数模型的Twitter TCP拥塞窗口分析
H. Nuha, Sidik Prabowo
In this work, an analysis of Transmission Control Protocol (TCP) Congestion Window with traffic model of twitter using exponential distribution is presented. TCP is a popular reliable protocol used by many internet service. As social medias emerge and introduce new characteristic of traffic, it is interesting to evaluate the performance of TCP in the latest social media environment scenario. Twitter as top social media shows its influence by taking part of many political event in the globe. An exponential distribution traffic model of Twitter traffic is proposed and an experiment on evaluation of TCP congestion window is presented in this paper. A congestion window represents efficiency of TCP to adapt network condition since the metric shows the number of data transmitted in a single transmission. In stable condition, shared bandwidth carry out higher congestion window which makes transmission more efficient. Combination of high traffic flow and high bandwidth comes with lower congestion window variation with 0.58 where low traffic flow obtains higher variance with 1.15.
本文利用指数分布的twitter流量模型对TCP拥塞窗口进行了分析。TCP是一种流行的可靠协议,被许多互联网服务所使用。随着社交媒体的出现并引入新的流量特征,评估TCP在最新社交媒体环境下的性能是一件有趣的事情。作为顶级社交媒体,推特通过参与全球许多政治事件来展示其影响力。提出了Twitter流量的指数分布流量模型,并进行了TCP拥塞窗口评估实验。拥塞窗口表示TCP适应网络条件的效率,因为度量显示了单次传输中传输的数据数量。在稳定的情况下,共享带宽带来了更高的拥塞窗口,使得传输效率更高。高流量和高带宽组合的拥塞窗口方差较小,为0.58,而低流量组合的拥塞窗口方差较大,为1.15。

Hadoop High Availability with Linux HA Hadoop高可用性与Linux HA
Diamun Fikri Solissa, M. Abdurohman
This paper proposes The High Availability Method using Heartbeat and DRBD on Hadoop Namenode Failover. Implementation of Hadoop as computing process framework and media storage needs to be supported by the availability in case of failure. Cluster system utilization in Hadoop with many Datanode is one of the strength points. Stored file will be replicated in distributed datanode as blocks that makes if one the datanode server fails, the other datanodes server still has duplicates blocks. The problem in hadoop system, there is just one Namenode which is the communicator between users and Datanodes. While Namenode goes down then users can't access files stored in Datanode. This proposed method accomplishes the Namenode failover process. The use of this method is very effective because it can accelerate downtime with automatic failover formed by Heartbeat and real-time mirroring formed by DRBD. The results indicate that the use of DRBD and Heartbeat may accelerate failover time of less than 10 seconds.
本文提出了基于心跳和DRBD的Hadoop Namenode故障转移的高可用性方法。实现Hadoop作为计算过程框架和媒体存储,需要有故障可用性的支持。集群系统在Hadoop中具有多个Datanode的利用率是其优势之一。存储的文件将以块的形式复制到分布式datanode中,这使得如果一个datanode服务器出现故障,另一个datanode服务器仍然有重复的块。在hadoop系统中,只有一个Namenode,它是用户和datanode之间的通信器。当Namenode关闭时,用户无法访问存储在Datanode中的文件。该方法实现了Namenode故障转移过程。这种方法的使用非常有效,因为它可以通过Heartbeat形成的自动故障转移和DRBD形成的实时镜像来加速停机时间。结果表明,使用DRBD和Heartbeat可以使故障转移时间缩短不到10秒。

Implementation of Hadoop as computing process framework and media storage needs to be supported by the availability in case of failure. Cluster system utilization in Hadoop with many Datanode is one of the strength points. Stored file will be replicated in distributed datanode as blocks that makes if one the datanode server fails, the other datanodes server still has duplicates blocks. The problem in hadoop system, there is just one Namenode which is the communicator between users and Datanodes. While Namenode goes down then users can't access files stored in Datanode. This proposed method accomplishes the Namenode failover process. The use of this method is very effective because it can accelerate downtime with automatic failover formed by Heartbeat and real-time mirroring formed by DRBD.

SocioEmpathy: A Social-Sensitivity Application to Reduce Stress and Depression of Divorce or Domestic Violence Victims 社会共情:社会敏感性应用于减轻离婚或家庭暴力受害者的压力和抑郁
Arga Putra Panatagama, Guntur Putra Pratama, Dwi Yoga Wibawa
Divorce rate in Indonesia is the highest in the Asia Pacific. Meanwhile, the effects of divorce and domestic violence are so bad for children, especially for teenagers. The children of the divorce will show more anxiety, depression, and antisocial behavior than the child of a normal family. On the other side, the most important thing for people who are depressed is the presence of people who are willing to listen to them patiently and to not to underestimate the problem. However, depressed people don't always find people who are willing to do so when they are depressed. Thus, an application to facilitate them to share their stories and problems is needed, it is called SocioEmpathy. Methodology to develop SocioEmpathy is literature study based on scientific journals and books on ICT, and unstructured interviews towards divorce victim and professional psychologist. The result is a SocioEmpathy application that has features: 1) Timeline, 2) Personal Chat, 3) Panic Button, 4) Mood Tracker, and 5) Psychologist Consultation. The conclusion of this research is SocioEmpathy is expected to become a solution for divorce victims to ease their depression. On the other hand, the SocioEmpathy app also increase experience for psychology students and psychologists involved in this application.
印度尼西亚的离婚率是亚太地区最高的。与此同时,离婚和家庭暴力对孩子的影响是非常糟糕的,尤其是对青少年。离婚家庭的孩子会比正常家庭的孩子表现出更多的焦虑、抑郁和反社会行为。另一方面,对于抑郁的人来说,最重要的是有人愿意耐心地倾听他们的意见,不要低估这个问题。然而,抑郁的人并不总能在他们抑郁的时候找到愿意这样做的人。因此,需要一个应用程序来帮助他们分享他们的故事和问题,它被称为社会同理心。发展社会共情的方法是基于科学期刊和ICT书籍的文献研究,以及对离婚受害者和专业心理学家的非结构化访谈。结果是一个社会移情应用程序,具有以下功能:1)时间轴,2)个人聊天,3)恐慌按钮,4)情绪追踪器,5)心理学家咨询。本研究的结论是社会共情有望成为离婚受害者缓解抑郁的一种解决方案。另一方面,社会共情应用程序也增加了参与该应用程序的心理学学生和心理学家的经验。
