Abstract

The condition when the heart beats early is called the Premature Ventricular Contraction (PVC) Arrhythmia. Arrhythmia PVC conditions occur in the left ventricle of the heart. Almost every human will experience PVC arrhythmia during his lifetime. Arrhythmia PVC conditions that occur in a long time span can increase the risk of heart disease that leads to death. Examination of arrhythmia PVC conditions cannot be done independently and is quite expensive. AD8232 ECG Sensor Module, LCD 16x2, and Arduino Mega Microcontroller are used to detect PVC arrhythmia conditions. The K-NN classification method is used to classify 1 heartbeat cycle signal. The results of the K-NN classification are in 2 classes, namely the "Normal" class and the "PVC" class. The QRS Complex and Gradient R values of 1 heartbeat cycle signal will be used as parameters. heart conditions "Normal", "Bigeminy", "Trigeminy" are the output produced by the system. A total of 46 data were used as training data and as many as 23 data were used as test data in the classification of the K-NN method. The average value of program computation time is obtained by performing 10 times of program computation time testing. An accuracy value of 91.3% was generated from the results of the K-NN method classification accuracy testing. Testing the computational time of the program produces an average value of computing time of 1988.9ms.

Abstract

Each hospital or clinic practices independent management of data regarding medical health information is a major case that must be met if included in a large amount of data. The goal is to facilitate data processing and quality of service to clients. However, in Pedis Care Malang there are several constraints such as a system that is still manual in processing client data. Waste of time in recapitulating the client's medical data which is done twice a week for the same data and the difficulty of sharing data between each member, when one member requires client care data before in a rush. From the constraints that have been obtained, we need an information system that can manage client data in Malang's Independent Pedis Care Practices. The information system has several data processing features that include adding data, editing data, deleting data, printing, and displaying the history of the data entered and more efficient data storage. In addition these features make it easy to access data on each division member. For a more complete depiction of the features can be seen in the design of Work Breakdown Structure (WBS) which consists of 12 main modules. The study was conducted using the Rapid Application Development Method (RAD) as a system development method. The functionality testing is done using the unit testing strategy, integration testing, validation testing with 100% valid results. While non-functional testing uses compatibility testing, the results show that the system works well in all versions of the browser.

Abstract

Hate speech is a verbal hatred act that targets a group of people or parts of a particular community. In Indonesia, hate speech is increasingly found, especially on text-based social media such as Twitter. So that inspired the writing of this research, to identify hate speech on Twitter with the classification of tweets, especially those in Indonesian. The author chooses to use Improved K-Nearest Neighbor by using the BM25F term weighting, which is a weighting that considers the fields/streams in the document. So the tweet chosen as a training document and research test document, consists of 2 streams, the tweet and the hashtag. K-Fold Cross Validation testing (with K = 5) was performed on the parameter k for IKNN classification, bs, vs, and k1 for BM25F weighting, with 400 training documents and 100 test documents. The test results show that the determination of stream weight values ​​on BM25F sufficiently influences the results of the IKNN classification. Meanwhile the best final results for the F-Measure, Accuracy, Precision, and Recall of the average 5-Fold Cross Validation obtained were 79.77%, 68.80%, 68.80%, and 89.92% with k = 70, bs= 0,6, v1 = 2, v2= 5 and k1= 2 as the best value for each parameter.

Abstract

Malang city is one of the big cities in East Java which has experienced a fairly rapid population growth in the last seven years, as one of the big cities Malang City also has problems that are generally owned by other big cities, such as crimes. Malang City is one of the cities in East Java which has a high number of criminal cases with a lot of criminal cases occurring around the highway. One of the solutions that can be done to reduce criminal cases on the highway is to provide information about which areas that are vulnerable and which areas are safe to pass based on previous criminal data. Path searching is one of the ways to present that information. One of the path search algorithm that can be applied is the Bellman-Ford algorithm. From previous studies this algorithm was declared to be inefficient for large amounts of data but quite versatile and this algorithm can calculate negative weights and repeatedly check paths so that no path is missed. This research was conducted to create an information system that can provide safe path information also apply the Bellman-Ford algorithm and see the efficiency of the Bellman-Ford algorithm if applied to cases of searching for safe routes from criminal incidents in Malang City. From this study the results that obtained is the safe path information system that runs well and can be opened on multi platforms and also the complexity analysis results which is the efficiency of the Bellman-Ford algorithm, where in terms of time, the Bellman-Ford algorithm is less efficient because based on the analysis results, the order of growth of the time complexity is so the Bellman-Ford algorithm execution time increases quadratically, but in terms of space, Bellman-Ford is quite efficient because based on the results of the analysis, order of growth from its space complexity is n which means that the use of space increases linearly.
