Abstract

In the era of information technology vehicle numbers identification needs to be done by system automatically. Therefore, the accuracy of the data is well documented and work porses identification can be done quickly. Motor vehicle license recognition is a recognition system by comparing character feature in license plate with reference feature which exists in database. This system uses chain code method and template matching to extract character feature in license plate’s image. Feature extraction with chain code method will result in an array of direction codes which stored in dynamic array, which stored in dynamic array. In this application test feature will be matched with feature stored in database using dynamic time warping method (DTW) to obtain a distance value between test feature and reference feature, the smaller the distance obtained shows that both the features are more similar. The result of this system is the recognition of each character in license plate’s image. In this study, samples of license plate’s images are tested with the number of research objects. From the study feature extraction is obtained with template matching method provides better success rate compared to feature extraction with chain code method, where the success rate of feature extraction with template matching method is at 78% whereas feature extraction with chain code method is at 68%.DOI:http://dx.doi.org/10.11591/ijece.v4i2.5169

Abstract

Sales order documents at retail companies are a very important procedure in the project or work initialization process. However, the management of the sales order which is still done manually creates several problems in the process. This research will try to offer a solution by building a sales order management system that is developed by applying the Rational Unified Process (RUP) method. 4 stages in the RUP must be carried out, namely: the initial stage, the elaboration stage, the construction stage, and the transition stage. To reduce the risk of changes desired by the user, testing is carried out at the end of each phase. The results of this study have succeeded in building an SO management system where each feature designed is successfully implemented, which is indicated by the results of measuring the functional suitability of the system at each stage getting a value of 1.

Abstract

Sumber daya manusia merupakan salah satu faktor penting dalam sebuah organisasi yang mampu memberikan pengaruh besar pada organisasi. Pengembangan sumber daya manusia harus diukur untuk meningkatkan dan mencapai tujuan organisasi dalam menghasilkan sumber daya manusia yang berkualitas. Kinerja merupakan sesuatu yang dapat diukur dengan memberikan potensi dan kemampuan dalam menciptakan hasil dari tindakan yang dikerjakan. Untuk mengetahui tingkat kinerja dari sumber daya manusia yang dimiliki sebuah organisasi perlu dilakukan penilaian terkait kinerja atau kontribusi dari SDM tersebut. BARS adalah suatu metode dalam penilaian kinerja yang berdasarkan pada perilaku dari masing-masing individu. Penelitian ini bertujuan untuk mengetahui penerapan dari metode BARS dalam menilai tingkat kinerja pada organisasi swasta dan negeri. Hasil yang ditemukan menunjukkan bahwa penerapan metode BARS lebih banyak digunakan pada organisasi swasta dibandingkan dengan organsisasi negeri. Nilai yang ditunjukkan beberapa organisasi swasta lebih signifikan karena sudah mencapai dan hampir mendapatkan nilai tertinggi yang berarti melebihi tingkat nilai BARS dalam penilaian. Dalam hal ini organisasi swasta dan negeri memiliki harapan agar dapat menerapkan motivasi dan konstribusi yang baik dari setiap sumber daya manusia yang dimiliki agar mencapai tujuan dari organisasi.

Abstract

Epworth sleepiness scale is a self-assessment method in sleep medicine that has been proven to be a good predictor of obstructive sleep apnea. However, the over-reliance of the method making the process not socially distancing friendly enough in response to a global covid-19 pandemic. A study states that the Epworth sleepiness scale is correlated with the brainwave signal that commercial-grade EEG can capture. This study tried to train a classifier powered by CNN and deep learning that could perform as well as the Epworth with the objectiveness of brainwave signal. We test the classifier using the 20 university student using the Epworth sleepiness test beforehand. Then, we put the participant in 10 minutes EEG session, downsampling the data for normalization purposes and trying to predict the outcome of the ESS in respect of their brainwave state. The AI predict the reaching 65% of accuracy and 81% of sensitivity with just under 100.000 dataset which is excellent considering small dataset although this still have plenty room for improvement.
