Abstract

— In Vehicular Ad-Hoc Networks (VANETs), wireless-equipped vehicles form a network spontaneously while traveling along the road. The direct wireless transmission from vehicle to vehicle makes it possible for them to communicate even where there is no telecommunication infrastructure; this emerging new technology provide ubiquitous connectivity to vehicular nodes while on the move, The main idea is to provide ubiquitous connectivity to vehicular nodes while on the move, and to create efficient vehicle-to-vehicle communications that enable the Intelligent Transportation Systems (ITS). This is achieved by allowing nodes within certain ranges to connect with each other in order to exchange information. Since accident happens in split seconds, to avoid communication inefficiency, there is need for this information to get to the intended vehicle on time. To solve this problem, this work models each vehicle in a chain of others and how it responds to the traffic around it using Microscopic (also known as car-following) method for modeling traffic flow; driver- to-driver and driver-to-road interactions within a traffic stream and the interaction between a driver and another driver on road were considered. The essence of this modeling is to determine the minimum response time required for a vehicle in VANET to respond and communicate situations on the road. A simulated scenario was carried out for two vehicles, a leading vehicle and following vehicle. The result shows that with an average of 32 meters apart with average difference in velocity of   1.23m/s, a minimum of 0.9secs is required for efficient situation response communication to ensue between them.

Abstract

One of the IT applications implemented in higher education and quite rich in renewable IT features is e-learning. However, facts show that in Indonesia it appears that there are not many universities are moved to apply e-learning, in addition, from the other side for others who have implemented e-learning still leads to a pattern that has not been systematic according to its allocation.This paper will discuss the optimization and re-initiation of e-learning using a case study. In addition to reviewing the aspects of human resources involved in e-learning, the following features and functions can be developed in e-learning, such as collaboration, social networking, and so forth. This review is conducted considering that in addition to e-learning included in the top 10 topics in higher education, e-learning also has the potential as acceleration in the learning process and collaboration on campus..

Abstract

Tsunami is a high wave caused by tectonic earthquakes, volcanic eruption or landslides in the ocean.  Indonesia is one of the countries that has thousands of islands. Lots of towns is a city on the banks or waterfront city. Indonesia becomes Tsunami prone areas. Tsunami can affect damage in various sectors, namely land degradation and infrastructure, environmental damage, fatalities, even the psychological impact on the victims themselves. Therefore, it takes a clustering of tsunami-prone areas. The result of clustering can give information to the public to remain alert to the danger of the tsunami. Also, clustering of the tsunami can be used by a government to prepare policies in overcoming the danger of the tsunami. Improved K-Means is an approach that proposed in this study to clustering the tsunami prone areas. In selecting the initial centroid must be done properly to produce a high accuracy. We proposed a method to determine the initial centroid appropriately, so that can increase the accuracy. The proposed method is Particle Swam Optimization (PSO). This study also uses comparison methods, such as K-Means, K-Means Improved, and K-Means Improved PSO. This study uses silhouette coefficient to test the accuracy of the system. The result showed that the proposed method has higher accuracy than the comparison method. Silhouette coefficient generated at 0.99924223 with smaller computing time

Abstract

Abstract— Recognizing human hand gesture through the use of INS (Inertial navigation System) sensor, Hidden Markov Model (HMM) was used as a tool to recognize pattern statistically. Employing INS sensor to admit data input , it is assumed that hand gesture could be detected by analizing the acceleration and fluctuation from data sensor and the difference of hand-position in 3-axis. The INS sensor that was being used was came with 6 channels to generate signals of a 3-axis gyroscope and a 3-axis accelerometer. The acceleration fluctuated in three perpendicular directions due to different hand gestures was detected by the accelerometer, while the change of hand-position in 3-axis was detected by gyroscope. Data from sensor was exported to computer via USB (Universal Serial Bus) port.During the stage of data collection, a cut algorithm was developed to pick the most significant part of the sensor data. After finishing data comparison stage, DCT (Discrete Cosine Transform) was selected to transform the signal from time domain to frequency domain. Sequences of calculation were performed to analyze the best sampling frequency to select dominant frequency of every gesture to be picked as parameter value. The parameter value used in HMM as the approach to recognize and differs gestures. Index Terms—3-axis gyroscope, accelerometer, gesture, gesture recognition, hand gesture, human gesture.

Abstract— Blood is an important part of the body. Blood is divided into several groups A, B, O, and AB. Conventionally, detect blood group by dripping anti-A serum and anti-B serum into the blood to be recognized and direct measurement of the serum droplet reaction. This study will compare the processes that use segmentation and  without using segmentation to know the various segmentation information in introduction of human blood type image. From the test results that segmentation increase accuracy of recognition between 10% -24% of each test. By using JST Learning Vector Quantization (LVQ) as a classifier and Fuzzy C-Mean as segmentation, the optimal result on the system averages 92% to 98%.. Index Terms—Blood, Segmentation, Classification Abstrak–- Darah merupakan salah satu bagian penting dalam tubuh. Darah dibedakan menjadi beberapa golongan yaitu A, B, O, dan AB. Secara konvensional, mendeteksi golongan darah dengan cara meneteskan serum anti-A dan serum anti-B ke darah yang akan dikenali kemudian melakukan pengamatan langsung terhadap reaksi tetesan serum tersebut.  Penelitian ini akan membandingkan antara proses pengenalan yang menggunakan segmentasi dengan proses pengenalan tanpa menggunakan segmentasi untuk mengetahui seberapa besar pengaruh metode segmentasi dalam pengenalan citra golongan darah manusia. Dari hasil pengujian didapatkan bahwa dengan adanya metode segmentasi akurasi system pengenalan bertambah antara 10%-24% setiap uji coba. Dengan menggunakan JST Learning Vector Quantization (LVQ) sebagai pengklasifikasi dan Fuzzy C-Mean sebagai segmentasi citra darah dapat diperoleh hasil yang optimal pada sistem pengenala golongan darah manusia dengan prosentase keberhasilan rata rata 92% hingga 98%. Kata Kunci—Darah, Segmentasi, Klasifikasi Klasifikasi Jenis Golongan Darah MenggunakanFuzzy C-Means Clustering (FCM) dan Learning Vector Quantization (LVQ)

Abstract

Report handling on "LAPOR!" systemdepends on the system administrator who manually reads every incoming report [3]. Read manually can lead to errorsin handling complaints [4] if the data flow is very large and grows rapidly it can take at least three days and sensitive to inconsistencies [3]. In this study, the authors propose a model that can measure and identify the similarity of document reports computerized that can identify the similarity between the Query (Incoming) with Document (Archive). In this study, the authors employed term weighting scheme Class-Based Indexing, and Cosine Similarity to analyze document similarities. CoSimTFIDF, CoSimTFICF and CoSimTFIDFICF values are defined as feature sets for the text classification process using the KNearestNeighbor (K-NN) method. The optimum resultevaluation with preprocessing employ Stemming and the bestresult of all features is 75% training data ratio and 25% testdata on the CoSimTFIDF feature that is 84%. Value k = 5has a high accuracy of 84.12%
