Entropy and Information Gain Analysis on Low Cost BCI for Motorbike Users to Prevent Accident: Rolly Maulana Awangga, Syafrial Fachri Pane, Dinda Majesty and Moch Yusuf Asyhari

The phenomenon of mothers giving the wrong turn signal reminds us of the importance of giving a proper turn signal to other road users. Because the error gives the turn signal will have an impact on the occurrence of a massive accident risk. In the logistics business, it will never be separated from the mail carrier whose duty is to deliver packages. Duty as an introduction certainly has a high risk of accidents, besides having to be vigilant on the highway. The mail carrier must also think about the destination location of the package he will deliver so that the introduction is still looking for signs around to get to the location. This busyness, can result in incorrect giving of turn signal or not giving turn signal at all. So this study aims to analyze the possibility of making auto turn sign for post-delivery so that the delivery post can be safe and avoid the risk of accidents.

Design and Implementation of Node Gateway with MQTT and CoAP Protocol for IoT Applications: Ahmad Zainudin, Mohamad Fahmi Syaifudin and Nanang Syahroni

Internet of Things (IoT) model has limited interaction because devices must communicate within the same domain. In addition, if there is a new type of sensor relevant to a domain, the sensor cannot communicate because of domain differences. Because of these problems a system is needed to communicate between protocol domains. Communication between the multi-protocol domains of CoAP, MQTT and Websocket on the device can be achieved by creating a gateway for each protocol, then connecting with a broker. Each data from the sensor will be processed into ESP32 as a microcontroller. To overcome the problem of the differences in multi-protocol domains, namely by making a gateway on a one sensor that uses the MQTT Protocol and other sensors using the CoAP protocol. The sensor data is processed by the Raspberry Pi as a multi-protocol gateway. Then the data are multiplexed and be sent to the database server using the Web socket Protocol. From the testing result show that the CoAP protocol has a better performance than MQTT protocol. The delay of CoAP protocol achieved 28.80 ms and the delay of MQTT protocol is 39.59 ms.

Level Crossing Rate Impact on Routing Performance in Adhoc Networks for Device-to-Device Communication: Istikmal Istikmal and Edwar Edwar

In the actual environment, device-to-device (D2D) communication on an adhoc network experiences rapid signal quality changes. The variation in the amplitude and phase of the received signal is due to changes in the characteristics of the path over times which are affected by distance and multipath fading between the sender and receiver. This will affect the performance of routing connection in D2D communication. In this research, we investigated the impact of level crossing rate (LCR) on routing quality connection in adhoc network for D2D communication. LCR is quantifies how often the fading signal is below the threshold value which is usually to measure of the rapidity of the fading. The simulation result shows that higher LCR indicate low quality routing connection and reduce throughput performance. The multipath fading and the velocity lead higher level crossing rate in routing connection. Threshold signal level play important role in determining the level crossing rate and quality routing connection in path selection mechanism.

A modern city is characterized by many buildings for commercial and residential purposes. Disaster mitigation such as building fires, earthquakes, and so on should be taken into account in city management. Mitigation seeks to reduce the level of risks when a disaster occurs. A proper mitigation requires an early warning system to alert the city authority in order to handle a disaster effectively. This paper describes the prototype of a building monitoring system using an internet-of-things platform for supporting the disaster mitigation in the city. It employs a temperature sensor, a smoke sensor, and a vibration sensor to detect the condition of temperature, smoke concentration, and the presence or absence of vibrations as an indication of an earthquake respectively. All sensor data is pooled in XBee transmitter module to broadcast into XBee receiver module. The data is sent continuously through the ESP-8266 module such that an internet-of-things platform called Cayenne will proceed the data by displaying the condition of building and alerting a warning message. If there is an indication of a fire or earthquake, then such message will be displayed in the Cayenne dashboard and sent to the registered mobile phone number. Experimental results show the Cayenne dashboard can display data related to the condition of the building at any time and a warning message can be displayed whenever indications of a fire and earthquake.

The era of millimeter wave (mmWave) spectrum with operating frequency range 30-300 GHz is coming. These frequencies are potentially used by 5G cellular communication since it has some benefits such as larger bandwidth and capacity. Energy efficiency is a crucial issue in 5G mmWave where it employs a large number of antenna array with power consumed ADCs (Analog to Digital Converters). This paper studies the efficiency of energy for mmWave communication through the optimization of ADC bits quantization. We use Channel Structure-based Scheduling (CSS) algorithm for evaluation with the total rate used as a performance parameter. The selection of quantization bit must consider the complexity of implementation. The simulation uses 2 bits quantization to explore the total rate performance. Then increasing bit number into 3 bits and 5 bits in the following simulation. The total rate increases as transmit power increases for the entire implemented quantization bit number. The random scheduling algorithm is used as a reference for comparison. The simulation shows that Channel structure-based scheduling algorithm outperforms random scheduling.

Effect of Giving N Value on ADASYN-N Method for Classification of Imbalanced Nominal Data: Sri Rahayu, Jeffry Andhika Putra and Yumarlin MZ

Class imbalances in data mining research are quite detrimental because there are difficulties in classifying minority classes (small number of instances) correctly. Oversampling is a method of balancing class distribution by randomly replicating instances in minority classes. multiclass classification might achieve a lower performance than binary classification as the boundaries among the classes may overlap. This issue may become more complex when facing imbalanced data. This study presents test results giving different k values in nearest neighbor searches which are used to balance the class using the ADASYN-N method. The results show that giving different k values can affect the performance of the ADASYN-N method depending on the number of dataset instances.

Classification of Citation Sentence for Filtering Scientific References: Ghoziyah Haitan Rachman, Masayu Leylia Khodra and Dwi H Widyantoro

Citation sentence is able to inform readers about relation between scientific articles that cite and are cited by finding its purpose against the research. Besides giving credit to other researchers and recommendation to read other related articles, citation can help readers to know what knowledge they have obtained based on the cited scientific articles they have read. In this research, we try to define citation categories for filtering scientific references which will be initial step in guided summarization of scientific articles. Our goal is to classify citation sentence first into 'problem', 'use' and 'other', then 'use' will be divided into 'useModel', 'useTool' and 'useData'. This category will make it easier to classify scientific articles into more specific topics. Then we use features namely voice, tenses, citation location, meta discourse and word vectors. Then, the testing of models show that the classification of citations using SVM Linear has the f-measure of about 67.7%. Moreover it is good enough when the test data is only one paper with the result of f-measure can reach 89.6%.

Indonesian Part of Speech Tagging Using Hidden Markov Model - Ngram & Viterbi: Denis Eka Cahyani

Part of Speech (POS) Tagging is a process of labelling word classes on sentences. One of the POS Tagging problems is some words that spelt the same but have a different POS Tag depending on the context of the sentence (ambiguity). The approach to solving this problem is using the Hidden Markov Model (HMM) Ngram Algorithm and the Viterbi Algorithm. This study discusses the development of a system for Indonesian POS Tagging using the HMM N-gram algorithm (Bigram and Trigram) and the Viterbi algorithm and compares the result between the HMM Bigram and HMM trigram. An Indonesian language corpus that has been manually labeled called Indonesian Manually Tagged Corpus is used as the knowledge for the system. Then the corpus is processed using the HMM N-gram algorithm to get the rules. Furthermore, process the data with Viterbi algorithm using the previous formed rules to determine the POS tag with the highest probability. The highest accuracy results is 77.56% using the HMM Bigram - Viterbi Algorithm. While the HMM Trigram - Viterbi algorithm has the highest accuracy of 61.67%. The result shows that the system can solve the problem of tag ambiguity with HMM Ngram - Viterbi algorithm and the accuracy of HMM Bigram is better than the HMM Trigram.

Mobile Business Intelligence Assistant (m-BELA) for Higher Education Executives: Mohamad Irwan Afandi, Eka Dyar Wahyuni and Siti Mukaromah

In the era of Industrial Revolution 4.0 marked by the use of information technology, the Internet in particular, university executives, as well as executives in companies, are often in such a situation which forces them to conduct business intelligence activities ranging from simply accessing data and information to analyzing them to support their decision making whenever and wherever they are. Typically, university executives are able to access data and information not only from their university databases through their web applications but also from other data sources using internet browser installed on their laptops or mobile devices. However, information access model using web application tends to be rigid where the order of menu, layout, and user-interface provided are static which forces the user to memorize or search for the right place to find the data and information needed. Certainly, this model cannot keep up with the dynamic information needs. This study produces a mobile-based application named m-BELA which functions like a human personal assistant equipped with pre-defined data, information, and knowledge who is able to interpret user's voice command and then responds appropriately by following conversation or providing data and information relevant to the command. This new solution offers a competitive advantage since the user does not need to load a browser, open the web application, and then search for the menu and UI which provide information needed.

In a wireless adhoc network, routing protocol plays an important role to find communication path. In this research, we investigated proactive and reactive routing protocol performance in a more realistic environment with dynamic network topology scenarios. We compared Dynamic Source Routing (DSR) as reactive routing protocol and a proactive routing protocol Optimized Link State Routing (OLSR). We used Rician and Rayleigh propagation model as a multipath fading model for more realistic environment in mobile adhoc network. We focus on network topology change scenarios by increasing number of nodes and behavior of the node. The results shows that OLSR have advantages which gain higher throughput and smaller end-to-end delay compare to DSR in Rician and Rayleigh environments due to multipoint replying (MPR) strategy. However DSR have more efficient in packet routing control with smaller normalized routing load. For dynamic topology change in Rician and Rayleigh fading, OLSR performs more stable and can gain higher performance than DSR.

A Novel Ant Colony Optimization Algorithm for Waste Collection Problem: Sarifah Putri Raflesia and Anugrah K Pamosoaji

Waste management, especially waste collection issue, has been an ultimate global issue. Particularly, problem of collecting waste in minimum time, especially in big cities, becomes a challenge that needs solution. In this paper, this problem is approached by a well-known problem called Vehicle Routing Problem (VRP). The objective is to generate collision-free trajectories along the process of collection while minimizing the travelling time of the slowest vehicle. A novel method to solve such the problem, namely, Augmented-Node-based Ant Colony Optimization (ANACO), is introduced. The main feature of this method is the generation of trajectories, i.e., paths and velocities, of all waste-collection vehicles. The advantage of the proposed method is in the ability to provide velocity information besides path, which is totally different to the typical ACO algorithms that only provide path information. By the proposed method, the travelling time of the slowest vehicle can be minimized. Therefore, the requirement of fast-collecting capability can be satisfied. Simulation results are presented proving that a minimum-time and collision-free trajectories can be generated to solve the problem.

The Mapping of Lighting Intensity from the Light Distribution on LED and CFL Lamps: Herlina Wahab and Rudy Setiabudy

Electricity is an essential need for humans, specifically for the lighting function. Lighting is needed to aid humans visually perceive objects in areas that require lighting, both at night and during the day. At this day, there are two types of lamps that are extensively employed, particularly the type of Light-Emitting Diode (LED) and Compact Fluorescent Lamp (CFL). The adoption of lights in an area takes a lot of energy, so it is particularly crucial to choose the appropriate type of lamp that is adequate to perform effectively and efficiently. To determine the light distribution of the two types of lights, it is crucial to investigate the distribution of light. The investigation was carried out by the direct measurement technique on 6 and 8 watt LED lamps, as well as on CFL lamps 11 and 14 watt using luxmeter in an area projecting 3 x 4 meters. The analysis range is varied in several horizontal and vertical points. From the assessment results it was noticed that the LED and CFL lamps the value of the light intensity reduces if the horizontal and vertical distance of the measurement point are far from the lamp. The ends of the light distribution mapping discovered that the light distribution on the LED lights is better indeed and brighter at each point. This is because all the electrons recombine with holes. Whereas in the CFL lamp there has been a filament heating and ionization between the electrons with argon gas and mercury vapor which generates another energy which is relatively large heat energy.

Fingerprint Presence Fraud Detection Using Tight Clustering on Employee's Presence and Activity Data: Irfan Kamil and Bambang Pharmasetiawan

Detecting fraud in fingerprint registration poses a unique challenge as we cannot rely on an existing employee's attribute. Furthermore, analyzing using supervised algorithm cannot handle unlabeled data that generated uniquely for this case. We study the patterns of employee's presence and activity report data and found that fraud action tends to be closely similar to other fraud action. Therefore, we propose a tight clustering method to detect fraud in fingerprint data using DBSCAN algorithm, as tight distance calculation removes non-fraud data because non-fraud data is generated to be unique naturally

Trending Topic Classification for Single-Label Using Multinomial Naive Bayes (MNB) and Multi-Label Using K-Nearest Neighbors (KNN): Denis Eka Cahyani

Trending Topic is one of the features found of Twitter in a short text. However, the short text used as a trending topic on Twitter sometimes confuses its users, so they need to be classified into several labels, but one tweet can have more than one label called multilable. The lables are politics, sports, entertainment, tourism, business, and other news. Another problem is the multi-labeling of classifications. single- label will classify a trending topic into one label, while multi-label classifies into more than one label. This paper aimed to classify Twitter's trending topic using Multinomial Naive Bayes (MNB) for single-label data and K-Nearest Neighbor (KNN) for multi-label data. The steps were to collect trending topic data along with their tweets, labeling and text preprocessing, weighting TF-IDF, single-label classification using MNB and multi-label classification using KNN with the Binary Relevance approach, finally evaluation and analysis of results. By using K=3, the results show that KNN have 88.05% accuracy for multi-label data, whilst, MNB has a good result for single-label data 82.53% accuracy.
