Abstract

Motor induksi merupakan jenis motor yang paling umum digunakan. Untuk mendapatkan motor induksi yang handal maka perlu dilakukan perancangan yang optimal. Banyak parameter yang mempengaruhi kehandalan dari motor induksi, baik itu dari segi efisiensi, keamanan dan ekonomi. Oleh karena itu perlu dilakukan simulasi untuk mengetahui bagaimana kualitas dari desain motor induksi yang dirancang. Pada penelitian ini, akan menganalisis medan putar motor induksi tiga fasa yang merupakan salah satu faktor penting dalam kerja motor induksi tiga fasa. Medan putar terjadi apabila kumparan stator dihubungkan dalam fasa banyak, umumnya 3 fasa. Terjadinya medan putar dipengaruhi oleh beberapa faktor. Pada penelitian ini, didapat bahwa perbedaan jenis beban tidak mempengaruhi karaktersitik dari medan putar motor induksi tiga fasa. Intensitas kemagnetan dari stator maupun rotor motor induksi tiga fasa tersebut juga tidak memiliki perbedaan yang signifikan. Hanya saja terdapat perbedaan karakteristik dari kurva torsi dan kurva arus pada motor induksi tiga fasa dengan jenis beban yang berbeda.

Abstract

Thesis session is a process that must be followed by a student in order to account for the thesis that has been done. Thesis trial scores determine student graduation, and student graduation rates are used as a measure of campus quality. The problem is that many students are depressed and afraid in the face of a thesis hearing, not a few among students who are stressed in facing thesis and some even delay the work of the thesis so that it affects the trial value obtained. Besides that there are students who have good IP but the trial value is not good, and vice versa. This method the Artificial Neural Network using the Backpropagation algorithm was chosen because it was able to predict the graduation value of the thesis trial based on input from the value of the semester IP from semester I to semester VII and the value of the trial. The study was conducted in two ways, namely training and testing. The training process aims to recognize or look for expected results by using a lot of training, so that it will produce the best pattern for training the data. After the training reaches the goal based on the best pattern, it will be tested with new data to see the accuracy between the targets using Matlab R2014a software. Based on the results of testing using Matlab R2014a software, the results are convergent, with a target error of 0.2. From the results of the training and the tests carried out, it was predicted that the graduation score of the thesis trial was predicted to be 0.8727. This research can also help predict the graduation score of thesis students at STMIK Kaputama Binjai

Abstract

One feature of a smartphone device that is still often used is the exchange of messages such as text chat. This exchange of information generally knows no distance, can be far or close. This requires security of the confidentiality of information sent from the source to the target. One way to get the security of communication is by applying cryptographic techniques so that the message sent to the target can be secured. The cryptographic technique used in this study is Vigenere Cipher. The Vigenere Cipher algorithm is used to encode text conversations so that messages sent via the internet can be maintained as well as with confidentiality. The purpose of this study is to build a text conversation cryptographic application that can run on Android-based smartphone devices. The technique can encrypt text conversations into secret messages which then the results (messages) are sent using a message sending application such as SMS (Short Message Service), Whatsapp and Line. Then when the message arrives at the destination, the description is done automatically so that the original message can be read.
