Abstract

LPDP Scholarship (Education Fund Management Institution) is the most sought after by prospective students who want to continue their studies in the country, especially for those who want to continue their studies abroad. Recently, LPDP experienced problems related to students who received LPDP scholarships but did not return to Indonesia in accordance with the rules that have been stated. Starting from the incident on twitter, the topic of "LPDP" became a trending topic among twitter users. So it is our concern to find out and analyze public opinion through this twitter social media. By comparing the results of two methods, namely Support Vector Machine (SVM) and Naïve Bayes in classifying the twitter sentiment. As well as the calculation of accuracy using the Confusion Matrix, there are as many as 1000 tweets result from crawling. This research resulted in a classification that uses the Vader Lexicon Library built by NLTK, the Naïve Bayes method and Support Vector Machine (SVM) has not yet reached an accuracy rate of 70%. In contrast, the Support Vector Machine (SVM) method that uses the Vader Lexicon Library from VaderSentiment achieves an accuracy rate of 90%, with a ratio of 90:10 (training data: test data). Keywords: LPDP, Naïve Bayes, Sentiment Analysis, Support Vector Machine (SVM), Vader Lexicon.

Abstract

Sentiment information is one type of information that can be obtained from social media. Sentiments can be interpreted as opinions and views of society which contain feelings. To analyze the value of sentiment whether the sentiment is a sentiment that tends to be neutral, negative, or positive, sentiment analysis can be used. language has its characteristics and uniqueness, Bengkulu language is no exception, because of this, it is necessary to model sentiment analysis for various languages. Sentiment modeling for the Bengkulu language is not yet available, therefore a sentiment analysis model for the Bengkulu language is developed by applying Long Short-Term Memory (LSTM), and architectural experiments for Long Short-Term Memory (LSTM) are carried out to obtain an architectural sentiment analysis model that produces the best value. The data used in the study amounted to 24,000 Bengkulu-language comments received from social media Instagram, Twitter, and Youtube. Experimental research 1 produces the best accuracy value compared to the results of testing in other experiments, with an accuracy value of 0.87 a precision value of 0.80, a recall value of 0.82, and an F1 score of 0.81 Keywords: Information, sentiment, Long Short- Term Memory (LSTM), Bengkulu Language, architecture, social media.

Abstract

Pulmonary X-ray is a medical diagnostic method used to produce internal lung images. However, the X-ray process is often interrupted when capturing images, resulting in noisy image results. This condition diminishes the clarity of information contained in the lung X-ray images. Therefore, noise removal or denoising is essential. Denoising is a fundamental image processing technique aimed at improving image quality for optimal information transmission. This study applies denoising methods to 20 datasets of pulmonary X-ray images using Median, Mean, Gaussian, Bilateral, and Wiener filters, with Python and the OpenCV Library. Error measurement for noise filtering is conducted using Peak Signal-to-Noise Ratio and Mean Square Error methods. The research results show that the median filter stands out as an excellent denoising method, outperforming others with a Peak Signal-to-Noise Ratio of 37.6444 and a Mean Square Error of 11.3339 for Salt and Pepper Noise. Keywords: Denoising; Filtering; MSE; PSNR; X-Ray.

Abstract

The use of video conferencing has increased in recent years. Even though now the trend of activities is returning to going offline, video conferencing is still widely used for various needs. However, the available video conferencing platforms have limitations, so users are not comfortable using them. The Jitsi platform is used because it is based on open -source and claims that Jitsi has better quality if it is built using its own server. QoS testing is conducted to determine the quality of JITSI if it is built on a container architecture using Amazon Web Services virtual machines. The QoS parameters tested are throughput, packet loss, delay, and jitter. QOS testing is carried out in 2 scenarios using a virtual machine and a mobile phone to join into video conference rooms. In scenario 1 the highest QoS values obtained include throughput: 3128Kbps, packet loss: 0.012%, delay: 2.39ms, and jitter: 2.39ms. In scenario 2 the highest QoS values obtained include throughput: 1778Kbps, packet loss: 0%, delay: 2.82ms, and 2.82ms jitter. Meanwhile, the use of server resources increases in proportion to the number of users who join each test. Keywords: Video conference; QoS; Cloud; Container; JITSI.

Abstract

Motorcycle thefts that are rife in the neighborhood give rise to concerns that simply locking a motorcycle is not enough. With the advancement of technology, we can develop a security system on motorcycles to reduce theft rate. In the case of motorcycle theft, there are two motives for theft, including the ignition key that has been forgotten to be removed and the motorcycle contact jacked up with a key letter T. Researchers designed a physical touch code motorcycle security system using GPS which aims to monitor motorbikes using a smartphone in the event of theft. The method used in this research is Research And Development. Telegram is used for monitoring motorbikes. The results of the research have made a physical touch code device for a motorbike security system using GPS. Physical touch code can create security. Telegram alarms and notifications can work properly. Telegram can receive notifications if in contact condition on ≥ 9 seconds the secret touch point is not touched with a horn sound delay with notifications received an average of 2 seconds. Keywords: ESP32; IoT, Security System, Telegram.

Abstract

The PKU Muhammadiyah Gamping Hospital - Yogyakarta has the goal that processes related to administrative and documentation aspects are digitized immediately. Medical record officers at PKU Muhammadiyah Gamping Hospital - Yogyakarta, especially in the field of midwifery assessment, still use a manual system in managing and preparing patient data reports. This causes delays in submitting daily patient data reports and has an impact on reducing patient services. To overcome this, a digital recording device is needed, namely a web-based medical record information system. The method used by the author in developing this information system is using the RAD or Rapid Application Development model. The programming platform uses the CodeIgniter 3 framework and Bootstrap 4.6. Database management using MySQL. The purpose of creating this medical record information system is to facilitate the management of patient data which includes patient registration data, patient medical record recording data, and collection of patient master data. This medical record system is expected to improve midwifery assessment services. Keywords: Medical Record Information System, Midwifery Assessment, RAD, Digitalization.

Abstract

Learning media innovation is in line with developments in information technology. Many of the innovations being developed now utilize the fields of multimedia and mobile devices. These two fields have proven capable of producing interesting learning media and making it easier for students to learn learning material digitally. One of the learning materials that requires digital media is English. Many English learning applications have been developed but are not yet in accordance with the learning plans of teachers and students so they are not used directly in class. Based on these problems, this research developed an application for learning English digitally that can be used directly in classroom learning. Application development is carried out using the waterfall method and is adjusted to the learning plans of school teachers. The results of application implementation are tested on all users through user assistance and filling out surveys. From the results of testing the application using black box testing, it was found that the percentage of 100% of the functions ran as expected. From the results of the application validation test, a score of 86.5% was obtained for material suitability from material experts, 83.8% for media suitability from media experts, 82.6% for useability from educators' assessments, and 81% for useability from students' assessments. From the overall validation test results carried out on material experts, media experts, educators and students, the overall average validation results were 84.37%, which shows that the Easy Tenses application created can be categorized as very suitable for use. Keywords: Applications, English, Digital media, Multimedia, Waterfall Method.
