Abstract
Disaster Management System (DIMAS) is used to reduce risk caused by disaster by manage information about affected area by disaster. It also manage aids, volunteers, and refugees data to measure effect of disaster accurately. Most of DIMAS controlled by government and operated by verified volunteers to keep data integrity so it can be accounted for future purpose. In this paper, we propose to apply DIMAS to mobile environment because of advantages that can be utilized to simplify the usage of DIMAS like GPS integration, mobility aspect, real time data capturing, etc. At the result, we hope it can improve accuracy and speed of collecting data in affected area.

Abstract
Autograder is used to measure source code quality based on blackbox testing. It will compare source code execution result with existing test cases and generate grade based on comparation result. Autograder can be used in college to help lecturer to test students skill in programming. It can be applied in laboratory or online course so students can use it to test their skill. Most of autograder use centralized architecture which it just execute and grade only one request at a time so if students submit their code to test, it will create a long queue and can risk highly to cause timeout because of long queue and unexecuted request. In this paper, we propose to apply distributed architecture for autograder to reduce queue and lower the risk for unexecuted request that can cause error in grading.

Abstract
Along with the development of technology that enters all walks of life including agriculture provides an opportunity for farmers to be able to trade agriculture directly because of the problems that occur in the distribution of agricultural products for quite a long time so that they are directly in hand. Consumers sometimes make farmers quite disadvantaged because they get income that is not comparable if sold directly to consumers (end users). But the limited space and lack of information make it a problem for farmers to sell it directly. E-commerce is one solution to this problem. E-Commerce is a forum that brings together sellers and buyers in buying and selling transactions directly using online electronic devices. The software development methodology used is the XP (Extreme Programming) method. The results of this study are in the form of e-commerce applications that can be used as a medium for promotion, communication, information and provide direct benefits to farmers and consumers. The application testing technique using the Black-Box Testing method is Equivalence Partitioning. The results of the study used a user questionnaire that the application had a percentage value of 88.84% included in the excellent category.

Abstract
Key-based security is still the most widely used form of security today with a key distribution process between senders and receivers that is commonly perform and also it is a classic problem in cryptography where key must be share to other parties (sender or receiver) and its maybe known when third parties do sniffing process or man in the middle attack. Three-Pass Protocol is one solution that can be used to overcome the problem of key distribution, because the sender and receiver can encrypt and decrypt without need to exchange keys. Security in Three-Pass Protocol uses XOR logic so that the resulting ciphertext will be very easy to decrypt by those who are not responsible, to improve data security in the Three-Pass Protocol process which is use Caesar Cipher and Vigenere Cipher algorithms in the encryption and decryption process in the Pass Protocol scheme, and ciphertext encryption results are quite difficult to read and require a long time to decrypt them.

Abstract
In the supervised machine learning framework sufficient labeled data are needed to achieve satisfying performance. In many domains, however, the labeled data are often expensive to obtain and requires laborious human effort. In this paper, we propose a query technique by introduce the expected log-likelihood as a criterion to minimize the training data in active machine learning framework. In this scenario, the expected log-likelihood is calculated for all unlabeled data points then an instant with highest value is chosen to be labeled. Some experiments were conducted to test the effectiveness of the method using the Gaussian mixture model classifiers with different number of kernels for each class. The method was applied on a training and test data set generated from the two normal distributions with the same proportion for each class. The result of the experiments using the proposed method show a significant reducing of the labeled data compared with the passive learning method. On the data set, the passive learning reached an error rate of 4.50% after 81 queries, meanwhile the same error was reached after 36 queries by the active learning technique or 1,25 times faster than passive learning.

Abstract
Electroensephalograph (EEG) is a device that can capture electrical activity in the brain and inform the minds condition such as emotional, fatigue, alertness, health and concentration level. Modeling the EEG signal before classification needs to be done, several studies have been carried out using Wavelet, Power Spectral, or Autoregressive transformations as feature extraction. This study explains the application of K-Nearest Neighbor as a classification and Fourier transform by taking the value of Power Spectralfor feature extraction from the wave signal Electro Encephalo Graph (EEG). This study aims to identify EEG signals used for cursor movements. The data used are EEG data originating from the 2003 BCI competition (BCI 2003 Competition). The data contains data class 0 (for movement of the cursor up) and class 1 (for movement of the cursor down). Decision making is done in two stages. In the first stage, the Power Spectral value for each EEG signal is used to extract the feature. The feature is input to K-Nearest Neighbor. In the second stage of the identification process into two classes (class 0 and class 1) EEG signal data files, there are 260 EEG signal file training data and 293 from EEG signal file testing data, so that the total becomes 553 EEG signal data files. The results obtained for the classification of EEG signals are 85.6% of the signal data tested

Dili is the capital city of Republic Democratic of Timor Leste country with a promising tourism potential because Dili has beautiful beaches and interesting cultural diversity. But until now these tourist objects are not widely known. The problem related to there is no media such as website that can promote tourism in Dili more detail and easily accessed by local and international tourists. Therefore it is necessary to create a geographic information system that becomes a media campaign for tourism of Dili City, especially about these attractions to be known by the public. The method used in solving the above problems is Waterfall which has the following phases: preparation phase, analysis and design phases, implementation phase, testing phase, deploy and maintenance phase. The programming tools in developing this geographic information system are PHP language and MySQL as the database. This web-based geographic information system will contain the data related to location of tourism and public facilities such as hotels, restaurants, shopping center, distance between locations and road conditions to make it easier for tourists during their stay in Dili. The system also provides updated information that is easily accessible to the public.

Abstract
The GOST algorithm is an algorithm that has good encryption and decryption speeds because the encryption and decryption process is simple with the use of keys that are not too good. Security in cryptographic ciphertext results is one of the factors that depends on the use of a good key too, one of the techniques that can be used is the Triple Transposition Key that processes keys as much as 3 x rounds with the transposition function. The Triple Transposition Key and GOST algorithms are combined during the key formation process so that the key obtained from the process of using the Triple Transposition Key algorithm is quite strong and minimizes the brute force attack. The use of the Triple Transposition Key algorithm on GOST can be used as an alternative to increase security on the key so that it does not have to have a combination of 2 or more algorithms that will only consume process resources and also do not significantly affect the speed of encryption and decryption.

Abstract
Limited time allocation for Islamic education in primary schools is a halt for the students to understand the lesson. The core of Islamic education is to understand reading and to write letters Hijaiyah. The concept of conventional learning patterns and lack of time made the level of understanding of students is low. To minimize this, learning media are needed that can attract students attention. Especially in children of the present era who are challenged with various types of technology, including mobile phones, televisions, and computers. The role of IT-based media can be a solution in current learning. In the learning process especially for children is learning that gives birth to a pleasant atmosphere. Images and sounds that appear will make children not get bored quickly so that they can stimulate learning in children. In learning that involves the media in the process of learning certainly must consider aspects of early childhood development. Augmented Reality can be utilized in various fields including education. In learning, there are Quantum Learning theories which explain visual, audio, and kinesthetic (VAK) methods. From here Augmented Reality and Quantum Learning theories are interconnected. In this application, there will be Hijaiyah letters that are simulated in the form of Augmented Reality with a sound for instructions on how to pronounce it. This application is expected to help the learning process of Hijaiyah letters both from among students and the general public outside of school, only by scanning the Hijaiyah letters from the Android camera.

Abstract
Cathfish cultivation in Indonesia is a very promising business opportunity with a big profits. Every year, market demand continues to increase. However, this is contrary with the lack of catfish farmers knowledge, so that catfish yields are not optimal. This is because, for certain types of catfish such as Sangkuriang catfish, it is easy to contract certain diseases. This study aims to create an automated system that capable of detecting catfish disease based on its symptoms with image recognition techniques. Early detection of catfish disease can help to find out the causes and prevention, so that the yield remains optimally. The method that used in this study is Principal Component Analysis (PCA) for feature extraction in images combined with K-Nearest Neigbor (KNN) with Euclidean Distance to classify catfish diseases among others: white spots, edema (abdominal swelling), jaundice, and bent spinal disease (scoliosis and lordosis). Based on the results of the experiment using 30 images data for training and 20 images data for testing, 18 image data is classified correctly. This result proves that PCA and KNN able to detect catfish disease well with percentage of accuracy around 90%.

Abstract
The application of IoT in Vehicular Ad-Hoc Networks (VANET) allows the realization of intelligent transportation systems to ensure the comfort and safety of road users. But as an implication, attacks that can interfere with this aim certainly need to be a significant concern. It is because the stakes are not only network security but also the safety of the driver and its passengers. One of the attacks which had a substantial impact on VANET was the Sybil attack. Sybil attackers illegally change into several different identities to carry out malicious activities such as disrupting routing, causing traffic jams, bottlenecks, and even accidents. Various security methods are introduced to VANET to detect Sybil attacks, but there are still several issues that have not been resolved. In this paper, we proposed the design of a defense mechanism against Sybil attacks. This mechanism aims to be suitable for application on IoT networks that have limited resources an also considering accuracy, privacy, safety, and real-world implementations. The proposed design uses a hybrid scheme with a trust-based method. Each node has an obfuscated identity to guarantee privacy. The trust center in the form of a Road Side Unit (RSU) will give a reputation value to each identity that will be evaluated periodically when in the range. Nodes form a fully distributed network when there is no RSU. It will use a data-centric neighbor trust scheme where its neighbors will assess each node based on the exchanging data. Each node reports on suspicious nodes to the RSU for evaluation. This mechanism allows RSU to evaluate suspicious node, which decides to isolate that Sybil node out of network.

Abstract
The ability of students to determine their chosen field of expertise is still subjective, many students choose the field of expertise because their classmates choose the field of expertise not by considering their abilities and interests. This research uses the KNN classification method to determine areas of expertise that are in accordance with student expertise. The KNN method was chosen because it is a method that uses supervised algorithms where the results of new query instances are classified based on the majority of the categories in the KNN whose purpose is to classify test data based on training data. This system was tested using the confusion matrix method and the results were 98.30% of the total student data sample of 30 people.

Abstract
Security issues and data confidentiality are very important in the digital and internet era today. Important files circulating on the internet, both in the form of documents, images, and videos need to be supported with good security. This article aims to secure files by utilizing steganography technology, both in encryption and decryption of the file. The method used is the Advanced Encryption Standard (AES) which is applied to Stego-Object. Experiments are done on document files with extensions .doc, .xlsx, .pdf, and .txt, also on image files with extensions .jpeg, .png, and .bitmap. The experimental results show that AES can encrypt and decrypt quite effectively without changing the quality of files both images and documents. This research can develop for video files.
