Abstract

In general, use case scenario reviewing is done manually, which has two drawbacks. The first drawback is the reviewing process takes a long time to finish, and the second drawback is the high level of dependence on reviewer's ability. Therefore, manual reviewing can lead into inconsistent scenario assessment. An automatic use case scenario review mechanism have existed before, but this mechanism was designed according to English which has some differences with Indonesian within the sentence's structure. There are some challenges to develop a use case defect detection system in other languages. Lexical database is needed as a reference for the system to recognize the processed text. Requirement writing template is also adapted to prevent complex writing of sentence structure. Those research results are the foundation for this research to develop a use case scenario examiner case tool in Indonesian. This case tool can manage use case scenario into a project, and examine those scenarios. Testing results on all aspects of the system are valid with a percentage of 100%, therefore therefore this system is feasible to use as a case tool to simiplify the use case scenario defect detection process.

Abstract

The heart is the center of the circulatory system for humans. In the heart, there are diseases or conditions that cause abnormal heart rhythms known as arrhythmias. Premature Ventricular Contraction (PVC) is an example of an arrhythmia that occurs when the ventricles have an unnaturally additional heart rate. If PVC occurs regularly, it can cause several other diseases including heart failure, coronary heart disease, and others, so it is necessary to check the health condition of the heart, namely by using an Electrocardiogram (ECG). In addition, the price of ECG medical equipment which is quite expensive and difficult to reach for some people is also the basis of this research. The author will use the triangular geometry feature and calculate the amplitude R value. The classification method applied is Artificial Neural Network (ANN) using the backpropagation algorithm. The test results of the ECG AD8232 sensor acquisition get an error value of 4.47% with 10 tests. This test compares the Beat Per Minute (BPM) value on the AD8232 and BPM sensors in real conditions. The results of the accuracy using the JST 3 hidden layer classification get 90% of the 20 test data used. For testing the computation time the system gets an average value of 235.5 milliseconds from the 20 tested data.

Abstract

Manual document checking process could take up a lot of time and may have a high error margin if it was not done thoroughly. One of its solution is by using an automatic document checker. An automatic document checker by its definition can significantly reduce the process time. In other words, more document can be checked in the same amount of time. In this research, we use journal from JPTIIK, an organization under Faculty of Computer Science, University of Brawijaya, as a base for the application research. The methods used in this research are string matching on the XML document. The program collects metadata that contains informations about the document, such as font types, font sizes, text modification such as bold, italic, or underline, margin, and many other data. This group of metadata will be compared to the set of rules set before on the application, which was based from the template provided by JPTIIK. The result shows that the program could detect mistakes on the journal and write it into a summarized PDF document that can be read easily by the user. The user then can uses this result as a guidance to fix their journal.

Abstract

Technological developments encourage the use of wireless networks and Wireless Sensor Network systems more and more. However, The problem with Wireless Network technology is the time difference between one node and another, on WSN each node communicates with the same frequency but has different local times, therefore there is a need for time synchronization. Time synchronization is a method for synchronizing the time on nodes on a network. There are several types of time synchronization, but this research focuses on the Timing-sync Protocol for Sensor Network (TPSN) method which is implemented over a wireless network using Bluetooth Low Energy (BLE) communication. The advantages of Bluetooth Low Energy are low power usage and efficiency, data transmission speeds of up to 1Mb / s and the potential for technology that continues to grow. This research using 3 BLE nodes which divided into 1 Server and 2 clients. This system uses ESP 32 as a microcontroller for data processing and Real Time Clock (RTC) as a timer for each nodes. The server node functions as a data exchange, and as the root node. The client node will request a request for synchronization to the server and the server will provide its local time as the reference time. From the implementation results, the error test data was obtained 30 times with the results of an average error value of 10.36 ms and synchronization testing as well as computation time was obtained 10 times with an average value of accuracy offset of 2.65 ms and Propagation Delay 16.85 ms, the computational average value is 102.3ms.
