Abstract

The rapid development of information technology makes the implementation of Internet-of-Things (IoT) increasingly common in everyday life. The IoT challenge is the ability to support devices with limitations and the Constrained Application Protocol (CoAP) is built to accommodate those problems. CoAP uses a client/server architecture that serves the request and provides the data respond requested by the user. This poses a problem when the client accesses the same resource simultaneously. This situation affects the workflow and makes it inefficient since it must do the same data request for all clients who needs that data. These activities may affect the performance of the server nodes which has limitations, and interfere the data transactions on the CoAP network. Therefore, the solution is by implementing a publish/subscribe architecture on CoAP in an IoT environment. The system uses broker that become bridges between publishers and subscribers, as well as data centers during data transactions. The test results show that the system has been able to run according to its functional needs, and the system has been able to run scalability test scenarios up to 250 users with a 0% error rate and has an average latency value of 74.5% smaller and overhead efficiency is 45.4% better than conventional CoAP. Based on these results, the system can be a solution to the problem of the IoT environment that has limitations.

Abstract

Cervical cancer is the second most common cancer in Indonesia after breast cancer. The number of deaths from cervical cancer in Indonesia continues to increase every year due to delays in making diagnoses and examinations. To detect cervical cancer, a laboratory examination using Visual Inspection with Acetic Acid (IVA) or pap smears is needed which requires specialist internal medicine and several considerations of features to get accurate diagnosis. Sometimes, how to analyze features by doctor with one another produces different results. Therefore, a classification process is needed to make a diagnosis of cervical cancer with high accuracy results so that it is expected to be able to match the diagnosis results of medical personnel. This study uses cervical cancer risk classification data with feature selection based on expert interviews. This study uses the Extreme Learning Machine algorithm to carry out the classification process and measure the results of algorithm performance with accuracy values ​​from the calculation of confusion matrix. Based on the test results obtained the optimal parameters are as many as 11 hidden neurons, the activation function is binary sigmoid, and the fold on training and testing data is fold 1st which produces an accuracy of 91.76%.

Abstract

Emotion shapes human behavior in general and very important in life. Detecting emotions provides an important role in various aspects because it can be applied in various fields such as decision-making, predicting human emotions conditions, providing a review product quality, tracking support for political problems, and recognizing depression disorders. Identifying emotions can use textual data that is text, text can be used to communicate and declare information. The social media that used to exchange information is Twitter. Twitter contains information about human attitude and human emotions. Therefore, emotional detection is needed to determine human emotions using Naive Bayes method and feature combinations. This research using several Naive Bayes classification models namely Bernoulli Naive Bayes for binary data types and Multinomial Naive Bayes for discrete data types. Feature Combination used in this research is as follows: linguistic features, orthographic features, and N-gram feature combinations. The best accuracy result obtained a value of 0.555 that is in testing N-gram feature combinations. While the combination of features including linguistic features, orthographic features, and N-gram features produced an accuracy value of 0.5317 which means this value was better than testing with a single feature and lower than testing the N-gram feature combinations. This is due to the influence of linguistic features, orthographic features, and N-gram features. Based on these results it can be concluded that by using combination features can cover the weaknesses of each feature that can improve the performance of accuracy even though the increase is not too significant.
