Abstract

PD. Sahati is a trading business that has been running since 2016. PD. Sahati has not utilized information technology effectively in its business activities. To avoid input errors, improve marketing and help with stock handling, a stock prediction sales system was made using the double exponential smoothing method and product recommendations using the a priori method.Data input for prediction is product sales data. Data used for predictions cannot be less than 3 months to maintain consistency in stock predictions. The test results from the double exponential smoothing method are indicated by the mean absolute error (MAE) and mean square error (MSE). The MAE value obtained is 0.375 and the MSE value obtained is 0.145. Data input for customer product recommendations in the form of customer transaction data are then searched for frequent itemsets based on customer transaction data and will be eliminated with a minimum value of support. The minimum support value is obtained from the number of transactions divided by 2. After that, the confidence percentage will be searched through the association rules table. The product that will be recommended later is a product that has a percentage of confidence above the minimum confidence value. The minimum value of confidence in the system is 70%.

Abstract

In this research, the main goal is to make an application to recognize people signature. To make this, we need the method to do our research. Backpropagation Neural Network that is used to train image sample and Feature Point Extraction for feature extraction. This method work with center point of the pixel image. The pre-processing are image binarization, Median filter, Thinning image with Zhang Suen algorithm, cropping, and  scaling for training image.. The method  for feature extraction is feature point extraction. This method works with counting the centeroid of the image. Number of total point centeroid is decide by depth value. The process will stop if the total point centroid is achived. After feature extraction, it will continue to train the sample image using Backpropagation Neural Network. Key wordsBackpropagation, Featurte Point Extraction, Image Binarization, Median Filter, Thinning, Threshold.

Abstract

The effect of the Korean Culture for the past few years has been increasing whereas the culture has been a part of the people’s daily lives especially for the youth. Unlike the Latin alphabet, the Hangul alphabet has the characteristics resembling strokes that’re written in blocks that make a syllable. Therefore, on this occasion a system will be made to recognize Hangul as an alternative for learning Hangul. The application design uses pre-processing such as grayscaling, thresholding, dilation and contouring. The data collected in this design uses as much as 3.960 images of the Hangul Alphabet. After GAN is used to generate images as well as Data Augmentation, the dataset reaches a total of 5.303 images which are separated into training set and testing set. The testing is done 2 times whereas the first test is tested on single letters and reached 55,58% accuracy. The second test is done with the letters that got segmented by the application which consists of 1-4 syllables whereas it reached 55,7-60% accuracy.

Abstract

Aplikasi yang dikembangkan terdiri dari 5 bagian, yaitu pengelolaan QR Code login, absensi dosen, absensi mahasiswa, realisasi perkuliahan, dan evaluasi kinerja dosen. Pengelolaan QR Code login dilakukan terhadap data dosen pada Fakultas Teknologi Informasi Universitas Tarumanagara (FTI UNTAR) dimana aplikasi yang dibuat digunakan untuk menghasilkan dan membaca QR Code sebagai sarana login. Pengelolaan absensi dosen dibuat untuk menghasilkan rekap absensi dosen FTI UNTAR dimana sistem yang dibuat terhubung dengan basis data mesin absensi yang ada. Pengelolaan absensi mahasiswa dibuat untuk menghasilkan rekap absensi mahasiswa FTI UNTAR pada setiap kelas mata kuliah. Pengelolaan realisasi perkuliahan dibuat untuk menghasilkan rekap monitoring dan evaluasi perkuliahan. Sementara itu, Algoritma Naïve Bayes Classifier digunakan untuk memprediksi kinerja dosen berdasarkan data absensi dosen, absensi mahasiswa, realisasi perkuliahan, dan pandangan kaprodi. Pemeriksaan telah dilakukan pada setiap modul yang ada pada aplikasi dan dapat disimpulkan bahwa aplikasi sudah dapat berjalan dengan baik sesuai dengan hasil yang diharapkan. Key wordsQR Code, Naïve Bayes Classifier, Rekap Absensi Dosen, Rekap Absensi Mahasiswa, Realisasi Perkuliahan, Monitoring dan Evaluasi

Abstract

This application uses artificial neural networks that generate value of the closing price on the day and uses three indicators of technical analysis to help estimate the movement of trading foreign currency price. The data used for input values is from price movements that occurred the previous day. Closing price refers to the combination of the opening price, highest price, lowest price, closing price and volume. After getting the value of the output in the form of today's closing price, then the next will be combined with the results of the estimated direction of movement of currency rates obtained by using three indicators : indicators Bollinger Bands, indicators DeMarker and indicators Moving Average Convergence / Divergence (MACD). The test results showed that the percentage of success is good for 85.22% and get a profit $ 9,448.

Abstract

The development of Church of Santa Maria de Fatima’s Website. Because the data displayed on the website is static, making it difficult to update. In other words, there is no information system in the website. The new website was built on PHP (Hypertext Preprocessor) programming language and utilising MySQL as DBMS (Data Base Management System). The method used in the development of this website is Prototyping. Based on the experiments that have been done, it can be concluded that the website has been made more dynamic. Thus, the data displayed on the website can be more easily updated and helps the management of the website

Abstract

No End Run is a 3D endless running game with the perspective of a third person and developed for Android smartphones. This game uses a touch screen and accelerometer sensor in the smartphone to control the character. As a running game, the character can run as far as possible, collect the collectables and avoid the monsters and obstacles. No End Run was made using the Unity game engine with C# as a programming language. Testing is done by Black Box testing, Alpha Testing and Beta Testing. The test results show that No End Run is an endless running game with interesting gameplay and has unique accelerometer controls so players are interested to play it again.

Abstract

In this paper, we propose a satellite image resolution enhancement technique based on wavelet transform by by combining the panchromatic image (PAN) with multispectral image (MS). To make the range of the coefficients consistent with the range of the PAN approximation coefficients under the same resolution, bilinear transform of the MS approximate image coefficient is computed before the merging. To improve image resolution used Wavelet Transform. Wavelet transform used is the Haar wavelet, Daubechies 2, Daubechies 3, Daubechies 4, Symlets 2, Symlets 3, Symlets 4, Symlets 6, Coiflets 1, and Coiflets 2. For analyzing the performance of the image resolution enhancement, we use performance evaluation. In the test results obtained that the most appropriate method for improving image resolution is Daubechies 2 to experiment without the use of resampling and Symlet 6 to experiment with the use of resampling. Key wordsBilinear Transform, Remote Sensing, Performance Evaluation, Wavelet Transform.
