Nowadays, people commonly use streaming technology to enjoy audio or video broadcasted from the server. With this technology, they do not need to download the content first. But, they can directly enjoy the content through the streaming mechanism. Generally, this technology requires high bandwidth to maintain its Quality of Service (QoS) to stay at a good level. The problem can occur, such as packet loss because of limited bandwidth supported by the network provider. This condition can reduce the quality of the content delivered. One technology that can be used to improve the quality of content delivered by streaming service is CDN (Content Delivery Network). This study is going to improve the quality of live video streaming by using CDN. The global CDN infrastructure used is Cloudfront, supported by AWS (Amazon Web Services). The broadcaster is located in Bandung, Indonesia, and the client is placed in Tokyo, Japan. HTTP Live Streaming (HLS) format is performed for content streaming. It is proved CDN can increase the QoS of content delivered. The result presents live video streaming with CDN has better achievement than the other one without CDN. The broadcasting of live video streaming gives a throughput average of 4452.6 kbps and a packet loss ratio average of 0.08% by using CDN. Without using CDN, it presents the throughput average of 3990.4 kbps and the packet loss ratio average of 0.33%.
现在,人们通常使用流媒体技术来享受从服务器播放的音频或视频。有了这项技术,他们不需要先下载内容。但是,他们可以通过流媒体机制直接享受内容。一般情况下,该技术需要高带宽才能保持良好的服务质量(QoS)。由于网络提供商支持的带宽有限,可能会出现诸如丢包之类的问题。这种情况会降低所传递内容的质量。一种可以用来提高流媒体服务内容质量的技术是CDN(内容分发网络)。本研究旨在通过使用CDN来提高视频直播的质量。使用的全球CDN基础设施是Cloudfront,由AWS(亚马逊网络服务)支持。广播台位于印度尼西亚万隆,客户端位于日本东京。内容流采用HLS (HTTP Live Streaming)格式。实践证明,CDN可以提高内容交付的QoS。结果表明,使用CDN的视频直播比不使用CDN的视频直播效果更好。采用CDN进行视频直播的平均吞吐量为4452.6 kbps,平均丢包率为0.08%。在不使用CDN的情况下,其吞吐量平均值为3990.4 kbps,丢包率平均值为0.33%。

Supervision of anomaly activities is very important to do in the network because it could be indicated as malicious activities. Network communication sessions are described in the form of port addressing communication or referred to as port address. In some digital crime events, they are using the port address to do dangerous actions on the network such as DDoS, Probing, R2L, and U2L activities. The grouping model of host activities on the network can utilize clustering theory, namely the neighborhood approach, or refer to as density based. By measuring the proximity of the two activities will be able to group the communication session data distribution from the host and map communication activities based on port access into normal or abnormal activities state. In this research, a new model to analyze port session communication using a density measurement approach to detect anomalous activities was proposed. The result shown that the proposed model can detect a cluster of the status an anomaly, which has more than eighty percent indicates high-risk activity. The proposed model is expected to be able to help network administrators to make decisions or actions from activities that are anomaly and dangerous.
在网络中,异常活动的监控是非常重要的,因为它可能被指示为恶意活动。网络通信会话以端口寻址通信的形式描述,或者称为端口地址。在一些数字犯罪事件中,他们利用端口地址在网络上进行DDoS、探测、R2L和U2L活动等危险行为。网络上主机活动的分组模型可以利用聚类理论,即邻域方法,或者称为基于密度的方法。通过测量两个活动的接近度,可以将来自主机的通信会话数据分布分组,并将基于端口访问的通信活动映射为正常或异常活动状态。本研究提出了一种利用密度测量方法检测异常活动的端口会话通信分析新模型。结果表明,所提出的模型能够检测出一簇异常状态,其中80%以上的异常状态为高危活动状态。所建议的模型有望帮助网络管理员从异常和危险的活动中做出决策或采取行动。

As a country with the largest Muslim population in the world, Umrah has become one of the forms of worship desired by most Muslims in Indonesia. In Indonesia, the umrah pilgrimage is commonly organized by a travel organization certified with excellent services as mandated in the regulations of the minister of religion. Service quality is a determining factor in customer satisfaction. Hence, this study was conducted to conclude whether a service was able to fulfill the needs, desires, and expectations of a pilgrimage trip. The main purpose of this study was to determine the quality of the umrah service. The approach of service quality used as a reference in this study is the Service Quality (Servqual) method. The Servqual method is a questionnaire used to determine service quality by measuring the gap level (G) between perceived services (P) and expected services (E), G=P-E. There are five dimensions of service quality that are used: reliability, responsiveness, assurance, empathy, tangible. In this study, we use the fuzzy Servqual method, which is a combination of Servqual and fuzzy theory, to produce more accurate values. There are 27 questions in the survey. The questions are consisting of five Servqual dimensions assessed by 151 respondents. The results of this study indicate that all dimensions of umrah services have a negative gap, the most significant gap is the assurance dimension, with the value of - 0.29.
作为世界上穆斯林人口最多的国家,朝觐已经成为印尼大多数穆斯林向往的礼拜形式之一。在印度尼西亚,朝觐通常是由一个旅游组织组织,按照宗教部长的规定,提供优质的服务。服务质量是顾客满意的决定性因素。因此,本研究旨在总结一项服务是否能够满足朝圣之旅的需求、愿望和期望。这项研究的主要目的是确定朝觐服务的质量。本研究参考的服务质量方法是服务质量(Servqual)法。Servqual方法是一种通过测量感知服务(P)和期望服务(E)之间的差距水平(G)来确定服务质量的问卷,G=P-E。使用的服务质量有五个维度:可靠性,响应性,保证,移情,有形。在本研究中,我们使用模糊Servqual方法,它是Servqual和模糊理论的结合,以产生更准确的值。调查中有27个问题。这些问题包括5个Servqual维度,由151名受访者评估。本研究结果表明,朝觐服务的各个维度都存在负差距,其中保障维度的差距最显著,其值为- 0.29。

Recently, renewable energy has become a popular natural resource to replace the fossil energy. So that its presence is increasingly being explored for use as a power plant. Solar energy is the most desirable and many methods are developed to capture the energy coming from the sun and convert it. The conversion process that is often encountered is by using solar cells. With the development of solar cell technology, more and more solar home systems (SHS) are being used based on the utilization of solar energy in load centers. SHS integrated into the electricity network is also increasingly connected to the system, so that it will have an impact on the performance of all three power transactions in progress. Therefore, in this study, the integration is evaluated using the financial value for each transaction based on energy exports and imports between customers and providers. The results show this has been done on the export-import of electricity during the customer's electricity consumption process, and the integration of SHS also contributes to the balance of the existing power stock. In addition, taking into account customer profiles, it can be seen that consumers have a profit of 14% customers 1, 15% customers 2, and 24% customers 3.
近年来,可再生能源已成为替代化石能源的热门自然资源。因此,人们越来越多地探索它的存在,将其用作发电厂。太阳能是最理想的,并且开发了许多方法来捕获来自太阳的能量并将其转换。经常遇到的转换过程是通过使用太阳能电池。随着太阳能电池技术的发展,基于负荷中心太阳能利用的太阳能家庭系统(SHS)得到越来越多的应用。集成到电网中的SHS也越来越多地与系统相连,因此它将对正在进行的所有三个电力交易的性能产生影响。因此,在本研究中,使用基于客户和供应商之间能源出口和进口的每笔交易的财务价值来评估整合。结果表明,在客户用电过程中的电力进出口已经做到了这一点,并且SHS的集成也有助于现有电力库存的平衡。此外,考虑到客户概况,可以看出,客户1的利润为14%,客户2的利润为15%,客户3的利润为24%。

This paper describes the design of a portable galvanic skin response (GSR) sensor for pain sensors. GSR sensors can measure electricity change in the skin. The signal results obtained are used to collect autonomic nerve responses as a function parameter of sweat ties. This response can increase the electrical conductance or increase the resistance in the palm. GSR is a psychological change in the skin resulting from the changes in sweat gland activity; at the time, the sweat glands will be active when the body is in a state of pain. This prototype was made to measure the conductivity of the skin, and the activity based on light blows to the arms. This prototype was made to measure the conductivity of the skin, and the activity based on light blows to the arms. Measurement was delayed by 1 minute to let the body rest before receiving physical impulse. The total time taken for the measurement is 4 minutes. This prototype uses an Arduino Uno microcontroller as an analog to digital signal processor, and the results will be sent to a PC using Bluetooth HC-05 via a serial plotter for display. The purpose of this research is to develop a prototype portable GSR sensor for pain sensors in the human body. The additional value of this research is to use Bluetooth as a data transfer to make it easier to use. The results of this study succeeded in developing a prototype portable galvanic skin response with good sensor sensitivity by verifying the data using a commercial galvanic sensor module.

There has been more content with various types needed by users. It comes from specific websites or databases. It causes a need to access the content through a retrieval system that can produce content that meets the demand. The existing searching applications still provide services aimed at only one particular modality, such as text, audio, or video. Therefore, research aimed at developing multimodal searching systems is still a significant opportunity in this field. In this paper, we review the multimodal information retrieval systems that have proposed in the previous research. And they discussed the components and mechanisms of the multimodal retrieval used by them. In this way, it will be clear on how they apply their approach to problem-solving on multimodality content searching. At the end of the discussion, there are some ideas or issues related to the problem.

To overcome the security problem of computer networks, the Intrusion Detection System (IDS) is developed. It is intended to identify an attack. Various types of IDS are built according to the environment: signature-based and anomaly-based. This second type of IDS can identify attacks that have not been known. In this case, machine learning is a possible method to develop an IDS model, which comprises many processes, including feature selection. The Boruta Algorithm is a feature selection method that is good enough to apply to machine learning. However, in its application on the NSL-KDD dataset, this algorithm has an infinite loop problem. This paper presents the analysis and estimation of random forest parameters, precisely the depth and number of trees; additionally, the use of entropy and Gini index as z-score in the Boruta Algorithm is considered. The experimental result shows that the proposed method can prevent the infinite loop, which indirectly improves the performance of the existing algorithm.
为了解决计算机网络的安全问题,开发了入侵检测系统(IDS)。它的目的是识别攻击。根据环境不同,可以构建不同类型的入侵检测:基于签名的和基于异常的。第二种类型的IDS可以识别未知的攻击。在这种情况下,机器学习是开发IDS模型的一种可能方法,它包括许多过程,包括特征选择。Boruta算法是一种足以应用于机器学习的特征选择方法。然而,该算法在NSL-KDD数据集上的应用存在着无限循环问题。本文给出了随机森林参数的分析和估计,准确地说是树的深度和数目;此外,还考虑了在Boruta算法中使用熵和基尼指数作为z-score。实验结果表明,该方法能够有效防止无限循环,间接提高了现有算法的性能。
