Abstract

Modified K-Nearest Neighbor (MK-NN) has been widely used to classify various types of objects. In carrying out the classification, MK-NN calculates the distance k closest neighbors in the training data. The difference between K-Nearest Neighbor (K-NN) and M-KNN is found in the process of calculating the validity of all training data and weight voting. The MK-NN algorithm calculation stage is calculating the distance between training data, calculating the value of the training data validity, calculating the distance between the training data and test data, and calculating weight voting. The biggest weight voting results taken are the number of K used. From the weighted voting results, the class of the largest weight voting value is the disease class from the test data. Potato plant data (Solanum tuberosum L) were used as many as 115 training data and test data with 7 types of diseases and 23 disease symptoms. The accuracy of this system depends on the k value and the total training data used. Big value of K make small the accuracy because the validity value obtained is smaller. The more training data used, the higher the accuracy because the difference between Euclidian grades between classes is greater. The best system accuracy is obtained from the value of k = 4 and total training data of 45 is 97.142857%.

Abstract

Swimming is a sport which done in water, either in fresh water or sea water. There is somewhat problem in choosing a swimming pool based in people's interest due to many available swimming pools in Malang city. Each swimmer in a group who had different preference on swimming pool also complicates the process of choosing pool among groups.There are three factors which affects people's interest in choosing swimming pool such as distance, ticket price, and pool's rating. Therefore, the solution to choosing swimming pool is by developing an Android based group decision support system. The system generates swimming pool group recommendation using Topsis Borda method. The system also uses criterias such as distance, ticket price, and pool's rating as reference for Topsis method. Distance criteria provided by measuring distance between user's location and swimming pool's location using GPS, thus the developed application is a location based service. The generated recommendations displays informations such as pool's name, a photo, distance between user and pools, ticket price, and pool's rating. Blacbox testing on implemented system reached 100% of functional validity. Algorithm validation testing is considered to be valid because the manual count and implemented Topsis Borda method count in the system shows the same results. Lastly, the usability testing on the implemented system obtained 84.5 score from five respondents. That score shows that system is on B grade, with user acceptance category as acceptable, and adjective rating as excellent on SUS Score.

Abstract

Al-Qur'an is the holy book which is owned by Muslims. This book is the main reference in living life for Muslims throughout the world. In order to become a good Muslim, each person must practice the contents of the Al-Qur'an. Before being able to practice it, of course a Muslim must be able to read and understand the contents of the Al-Quran. The process of learning to read the Al-Qur'an requires a lot of time and also a teacher as a guide. Regular practice is one solution so that the learning process to read the Al-Qur'an can be completed quickly. However, the teacher as a guide cannot always be there to accompany a student in learning to read the Al-Qur'an. From these problems, the author offers a way, namely an error detection application in reading the Al-Qur'an that can be used as a student training medium without time constraints. The writer developed this application using the Jaro Winkler Distance method as a method of comparison and assessing reading errors. This application makes use of Google's Speech Recognition to convert the voice input entered by the user to the depth of Arabic text. The results of the conversion in the form of Arabic text will be compared with the original text from the Qur'an using the Jaro Winkler Distance method. At the testing stage, the authors found that this method was very incompatible with the object of the Qur'an because the results of the accuracy testing carried out were very low.

Abstract

The heart is a vital organ that pumps blood throughout the body. A healthy heart beats neither too fast nor too slow, normally 60-100 times per minute. A heart that beats too fast up to 120-300 times a minute is called tachycardia. Ventricular tachycardia (VT) is a tachycardia that occurs in the ventricles if it lasts for a long time, can lead to congestive heart failure and death. Deaths caused by heart and blood vessels are in the highest rank in the category of non-communicable diseases, based on The Institute for Health Metrics and Evaluation (IHME). To prevent an increase in deaths from heart disease, the public is expected to be vigilant by checking their heart health from an early age. Cardiac examinations can only be done at health care service, therefore the aim of this study is to build a system that can detect VT that can be done alone anywhere. To build the system, the AD8232 module is used as a signal conditioner and Arduino Uno as a microcontroller. VT heart defects can be seen from the shape of the QRS signal and the rate of the heartbeat. The parameters to be used are the RR interval and the area under QRS. The classification method uses k-NN because this method is suitable if only a few parameters and data are used. From the research results obtained 90,47% accuracy for k = 3 and k = 5, 95,23% for k = 7.
