Abstract

The flow of news regarding the development of Covid-19 has dominated various information channels in Indonesia in the last 2 years, either through print media or digital media. Various types of news related to Covid-19 continue to circulate, including hoax news. One of the hoax news that is widely circulating is news about the Covid-19 vaccine. The rise of information containing hoax news and untrue rumors about the Covid-19 vaccine in society can worsen the pandemic situation. Currently there is no intelligent system capable of classifying hoaxes regarding the Covid-19 vaccine. To maximize prevention of the spread of hoax news about the Covid-19 vaccine and overcome the problems faced, the author designed a classification system for hoax news about the Covid-19 vaccine using a machine learning approach. The system built can classify news using a combination of the Name Entity Recognition (NER) and Backpropagation algorithms. The datasets used are: 600 Covid-19 vaccine news data obtained from the sites https://turnbackhoax.id/ and https://www.kompas.com/ with the keyword "covid vaccine". The dataset is divided into two, training data and test data. The training data is preprocessed and then used in model design. Test data is used to evaluate the results of model design. This process produces a machine learning model with a good accuracy level of 97.62%.

Abstract

To diagnose diabetic retinopathy is to segment the blood vessels of the retinal, but the retinal images in the DRIVE and STARE datasets have varying contrast, so the enhancement is needed to obtain a stable image contrast. In this study, image enhancement was performed using the Contrast Stretching and continued with segmentation using the Adaptive Thresholding on retinal images. The image that has been extracted with green channels will be enhanced with Contras Stretching and segmented with Adaptive Thresholding to produce a binary image of retinal blood vessels. The purpose of this study was to combine image enhancement techniques and segmentation methods to obtain valid and accurate retinal blood vessels. The test results on DRIVE were 95.68 for accuracy, 65.05% for sensitivity, and 98.56% for specificity. The test results of Adam Hoover’s ground truth on STARE were 96.13% for, 65.90% for sensitivity, and 98.48% for specificity. The test results for Valentina Kouznetsova’s ground truth on the STARE were 93.89% for accuracy, 52.15% for sensitivity, and 99.02% for specificity. The conclusion obtained is that the processing results on the DRIVE and STARE datasets are very good with respect to their accuracy and specificity values. This method still needs to be developed to be able to detect thin blood vessels with the aim of being able to improve and increase the sensitivity value obtained.

Abstract

Digital archive management in higher education institutions often faces challenges, including document fragmentation, inefficient retrieval, and data loss risks arising from semi-manual processes. This study aims to develop an integrated digital archive system to support personnel services for lecturers at Politeknik Negeri Lhokseumawe. The research employs APKL (Actual, Problematical, Public Concern, Feasibility) and USG (Urgency, Seriousness, Growth) methods for issue prioritization, followed by a Fishbone diagram for root cause analysis. The system was developed using a structured Software Development Life Cycle (SDLC) with a Human Resource Minimum Viable Product (HR MVP) approach. Evaluation via User Acceptance Testing (UAT) yielded an average score of 4.65 (Excellent category), indicating high user acceptance and system effectiveness. The implementation demonstrates that the system significantly improves document management efficiency, ensures data consistency, and accelerates personnel administrative services. This study concludes that the integrated digital archive system provides a robust, adaptive, and practical solution for enhancing administrative quality in higher education environments. Furthermore, the system incorporates intelligent software features, including automated document classification, proactive validation, and efficient search capabilities.
