Abstract

Multirate signal processing is critical to realizing the digital frequency converter in WLAN technologies. In this paper, we focus on designing and analyzing the different structures of decimators that support WLAN-b applications to reduce the frequency by 12 for an IEEE. The structure modeling of the decimator used Simulink. Implementing a single-stage decimator required a higher-order filter, extra storage space, and a long simulation time. Results showed that the necessary storage elements for 2-stage design are 55 percent and for 3-stage design is 65 percent of single stage. For 133 MHz WLAN-b application, a two-stage decimator is proved to be efficient.

Abstract

Lampung script fonts, in general, can only be used for typing on a computer system and have not been developed for typing on Android-based smartphones. Therefore, efforts to modernize and build typing using Lampung script for smartphone needs are very much needed on mobile phones so they can be used flexibly. This research makes a virtual keyboard / android keyboard application that can do typing using Lampung script. The virtual keyboard layout is designed by adopting several layouts found on the QWERTY keyboard by displaying all Aksara letters on one virtual keyboard display and grouping Aksara letters in a more attractive composition. To test the Lampung virtual keyboard script, the researchers used the usability testing method, namely aspects of effectiveness, efficiency, and user satisfaction, by 25 respondents. Through this test, an assessment of the effectiveness of the typing test on the success rate of respondents in doing the task was obtained, which was 75 percent. Evaluation of the typing efficiency aspect using time calculation gets the average result on the WPM score analysis, which is 34 WPM. This result is still below the average typing speed of people, which is 38 WPM. Testing on the aspect of user satisfaction using the system usability scale (SUS) method gets a SUS value of 76, and this result is included in the Acceptable/Good category Acceptable/Good so that users can type Lampung script through Android phones. The conclusion is that it can produce an optimal, efficient virtual keyboard layout and provide comfort for the user while using it with Android. It also could introduce the Lampung script to the younger generation.

Abstract

Multi-substrate antenna material is a combination of more than one primary antenna base material where this substrate material can determine the quality of antenna performance. A quantitative empirical approach is carried out to achieve maximum performance by processing the dielectric constant of the substrate to obtain other antenna parameters. This aims to increase the stability of the antenna gain and produce a large bandwidth. The results show that diamond has a bandwidth of 75 MHz with a maximum gain of 4.228 dBi and a VSWR of 18.017. While epoxy FR-4 produces a bandwidth of 57 MHz with a maximum gain of 3.444 dBi and a VSWR of 2.011, the quartz material produces a bandwidth of 80 MHz with a maximum gain of 4.426 dBi and a VSWR of 10.884. The conclusion is that FR-4 epoxy substrate performs better than diamond and quartz. It is hoped that the results of this research will impact the development of a smart antenna system.

Abstract

This research 0aims to design a Real-time ID card detection based on Optical Character Recognition (OCR). OCR detects and records information into CSV files using a camera. Hopefully, it can become one of the administrative solutions in Indonesia by using existing identity cards using OCR in real time. This research method was carried out independently in August 2021 using ID cards as objects. The tool involved was a 320x320 pixel webcam camera on an HP Intel Core i5 7th Gen notebook. The software used by Easy OCR was Pytorch-based. ID cards were detected using an algorithm by TensorFlow object detection with SSD MobileNet V2 FPNLite 320x320 as the pre-trained model of Tensorflow. The researchers collected ID card images using a webcam with various light conditions and orientations and label them using labeling. The researchers trained it with only 20 photos. After 3000 training steps, the researchers obtained about 0.17 loss and 0.95. Thus, the ID card detection tool using OCR runs well.

Abstract

Smart Village innovatively uses information technology to improve quality of life and efficiency. This study seeks to cover research gaps, contribute to the research field, and serve as a platform for primary probabilistic research by overcoming a proposed concept about The Community Reporting application as a solution for mobile phones. This application development uses the DART language with the Flutter Framework. The research stages are divided into four parts: problem analysis, literature study, system development, and report writing. The UAT test on the community reporting application got a score of 81.43 percent from community respondents. Furthermore, the community reporting administration system scored 88.3% of the village apparatus respondents. Therefore, the developed application could be well received. The government and community should contribute to implementing government and developing villages based on information technology.
