As a natural limited resources, the radio frequency spectrum should be managed and used as efficiently as possible. The Government as regulator has a responsibility to manage and regulate the spectrum to prevent interference. One example of the many problems in Indonesia that must be solved is the spectrum in 2.1 MHz frequency band for 3G services. The CDMA 2000 and UMTS system occupy adjacent band and that very potential to cause interference each other. The CDMA 2000 downlink channel which is separated by only 3.125 MHz guard band, have the potential to interfere the UMTS uplink channel. It is especially in the last channel with a center frequency of 1977.5 MHz. In this paper we evaluate an interference that occur between the two system by computer simulation and experimentally measurement. We propose three methods to cope with this problem, namely spectrum segmentation with sufficient separation band, geographical separation, and additional filters on the BTS. Antenna spatial isolation method is also used so that both systems can operate co-location in which the level of the interference is acceptable. With the arrangement of the antenna vertically by 1,1 meters separation, the additional attenuation of 15.2 dB can be obtained to reduce interference.
无线电频谱作为一种有限的自然资源,应尽可能有效地加以管理和利用。作为监管机构的政府有责任管理和监管频谱,以防止干扰。印度尼西亚必须解决的众多问题之一是3G服务2.1兆赫频段的频谱。CDMA 2000和UMTS系统占用相邻的频段,因此很容易产生相互干扰。CDMA 2000下行信道仅隔3.125 MHz保护带,有可能干扰UMTS上行信道。特别是在中心频率为1977.5 MHz的最后一个信道。本文通过计算机模拟和实验测量对两个系统之间的干扰进行了评价。我们提出了三种方法来解决这一问题,即利用足够的分离频带进行频谱分割、地理分离和在BTS上附加滤波器。天线空间隔离方法也被使用,这样两个系统可以在干扰水平是可接受的情况下协同工作。天线以1,1米的间距垂直布置,可获得15.2 dB的附加衰减,以减少干扰。

This paper presents the development of radio telescope receiver based on GNU radio and Universal Software Radio Peripheral (USRP). Usually an existing radio telescope receiver is only able to be used for fixed frequency and signal processing system; hence the other different frequency receiver needs to be carried out with different types of observation. Here, the development of radio telescope receiver includes the hardware system and the signal processing system. Then, the design of radio telescope receiver is developed based on GNU Radio and implemented by using USRP. From the result, it shows that the implemented radio telescope receiver which is applied for continuum observation can clearly detect signals at frequencies of 322MHz and 406MHz n which those frequencies are usually used in radio telescope.

This research consists of a classification system to determine the adult and benign image. Adult image in this research was defined as image that is perceived as pornographic by Indonesian people. The method in this research combines face detection and HS skin color detection on an image. Face detection is done by using the Viola-Jones method. After face detection process, skin detection is performed on the image. Based on the results of face and skin detections, a set of features is extracted and inserted into the classifier. The classification used in determining adult or benign image will be based on the percentage of face area in the image, the position of face in the image, and the percentage of the skin color in the image. For each feature, the threshold value is defined in this research. The results of the classifier is whether an input image is benign or adult images. From 30 sample images, the classification process classifies 5 pieces of images as benign images and 25 images as adult images. False positive rate are 2 images and false negative rate is 1 image with the accuracy of 90%.

This paper tried to design the implementation of WRAN 802.22 as a new proposed and interesting standard to provide broadband service in tv white space (unused spectrum digital television), specially in hard to reach and low density population area. With the standard parameter WRAN that have been drafted, we calculate the total amount of site needed in Banten, one of the province in Indonesia. In this paper, we use frequency 650 MHz, 30 dB transmit power, 10 m receiver's height and 30 meter of transmitter height. By using okumura hata propagation, Banten needs 245 site to cover all the area.

Nowadays, world is on going to “Convergence Era”, where data, voice, and video overcome to pass through same network, like IP network. Unfortunately, the fast growth of application technology has not been supported yet by default IP network in the case of quality of service. We have known, that voice over IP services have sensitivity to delay, jitter and latency. And it require of different bandwidth which is also required some service guarantee. How to comparing queue mechanism of VoIP attributed to QoS?. In this case, we need to give guarantee of QoS relied on operation of data packages to be delivered along with its scheduling. Scheduling represent queue mechanism from an applying of network QoS's, that is an arrangement process of an exit and entry of assumed data packages queuing exceed CIR (Committed Information Rate) specified. Regulation of this data exit and entry can be formed with specified classification. This research compare queue method of First In First Out (FIFO) with two algorithm type of WFQ scheduling which at most used, that is Class Based Weighted Fair Queuing (CBWFQ) and Low Latency Queuing (LLQ). Based on delay, jitter, and MOS (Mean Opinion Score) obtained, LLQ give a better network performance.
如今,世界正在走向“融合时代”,数据、语音、视频跨越同一个网络,如IP网络。遗憾的是,在服务质量的情况下,默认IP网络还不能支持应用技术的快速发展。我们已经知道,IP语音服务对延迟、抖动和延迟很敏感。它需要不同的带宽,也需要一定的业务保障。如何比较基于QoS的VoIP队列机制?在这种情况下,我们需要根据将要发送的数据包的运行及其调度来保证QoS。调度是一种应用网络QoS的队列机制,即对假定的数据包排队超过CIR (Committed Information Rate,承诺信息率)的出、入进行安排的过程。对该数据的出口和输入可以形成规定的分类。本文将先进先出(FIFO)的队列方法与常用的两种WFQ调度算法——基于类的加权公平队列(CBWFQ)和低延迟队列(LLQ)进行了比较。从时延、抖动和得到的MOS (Mean Opinion Score)来看,LLQ能提供更好的网络性能。

The development of technology is increasing rapidly. These developments have a huge impact on all areas, including The Health Field. Blood is one very important component in supporting the health of the human body. The lack of information about blood stock availability in hospitals and the Indonesian Red Cross (PMI) makes people often have difficulty in getting the blood they needs. Today many people are willing to donate blood to help people who in needs for blood, but time and cost became their main obstacle, because they need to find the nearest hospital or Indonesian PMI to do so. This application is built to be able to help people get information about existing blood stocks and provide media that can deliver information to people who want to donate their blood. This application is built using Hypertext Preprocessor programming language (PHP). The methodology use is Rapid Application Development (RAD) and using UML (Unified Modeling Language) as a modeling tool. The test result showed that this application is properly function and this application can assist the people in ordering the blood it needs and the people who wants to donate their blood without having to go to the nearby hospital or PMI.
科技的发展日新月异。这些发展对包括卫生领域在内的所有领域都产生了巨大影响。血液是支持人体健康的一个非常重要的成分。由于缺乏医院和印度尼西亚红十字会的血液储备信息,人们常常难以获得所需的血液。今天很多人都愿意献血来帮助那些需要血液的人,但时间和成本成为他们的主要障碍,因为他们需要找到最近的医院或印尼PMI这样做。这个应用程序的建立是为了能够帮助人们获得有关现有血液库存的信息,并提供可以向想要献血的人传递信息的媒体。该应用程序是使用超文本预处理器编程语言(PHP)构建的。使用的方法是快速应用程序开发(RAD),并使用UML(统一建模语言)作为建模工具。测试结果表明,该应用程序功能正常,可以帮助人们订购所需的血液和想要献血的人,而不必去附近的医院或PMI。

These developments have a huge impact on all areas, including The Health Field. Blood is one very important component in supporting the health of the human body. The lack of information about blood stock availability in hospitals and the Indonesian Red Cross (PMI) makes people often have difficulty in getting the blood they needs. Today many people are willing to donate blood to help people who in needs for blood, but time and cost became their main obstacle, because they need to find the nearest hospital or Indonesian PMI to do so. This application is built to be able to help people get information about existing blood stocks and provide media that can deliver information to people who want to donate their blood. This application is built using Hypertext Preprocessor programming language (PHP). The methodology use is Rapid Application Development (RAD) and using UML (Unified Modeling Language) as a modeling tool. The test result showed that this application is properly function and this application can assist the people in ordering the blood it needs and the people who wants to donate their blood without having to go to the nearby hospital or PMI.","PeriodicalId":371814,"journal":{"name":"2015 1st International Conference on Wireless and Telematics (ICWT)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123175727","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Anomaly traffic detection is one method to detect attack in internet, especially Distributed Denial of Service (DDoS). Here, traffic analysis which reveal the observed traffic pattern is key important process as the anomaly decision was taken based on traffic analysis. This research analyzed several statistical analysis of traffic datasets categorized as normal, DDoS attack and flashcrowd. Analysis done in aggregate and per-flow traffic level which showed similarity and difference in each category. Windowing technic used to measure instantaneous statistical value. The result showed several statistical difference which could be used to categorized types of anomaly, especially to identify normal threshold. Flow to normal average flow distance distribution perform not followed Gaussian distribution.
异常流量检测是检测网络攻击尤其是分布式拒绝服务攻击的一种方法。其中,流量分析是基于流量分析做出异常决策的关键环节,它揭示了观测到的交通模式。本研究对正常攻击、DDoS攻击和flashcrowd三种流量数据集进行了统计分析。在汇总和每流流量水平上进行的分析显示了每个类别的相似性和差异性。窗技术用于测量瞬时统计值。结果显示出一些统计差异,这些差异可以用于异常类型的分类,特别是用于正常阈值的识别。流量向正态平均流距分布不服从高斯分布。
