All that requires a media to understand each other and understand one another. The media is language. Language is a medium for communication so cooperation will be created in various aspects. English is the connecting language used as a medium of communication between countries in the world. But some people find it difficult when learning English. The difficulty experienced is due to a lack of understanding of grammar, one of which includes tenses. Learning media as a means of improving the quality of education is very important in the learning process. The research methodology used is waterfall method as an application development methodology. The first step to do is to analyze the needs of the system made, including library research, data collection, consultation, and design. From this analysis a system design using usecase diagrams, activity diagrams and class diagrams is made as a system design to be made. After the system is designed, the next step is to write the program code. At writing the programming language program code used is java, android studio and genymotion as an emulator. Blacbox test results show the software can find out the functions that are not correct, interface errors, performance errors and functionally produce the expected results.

Media sosial X menjadi gudang data yang dapat dimanfaatkan untuk memperoleh wawasan mengenai sentimen publik dan potensi yang berdampak pada harga cryptocurrency. Dalam beberapa tahun terakhir, bitcoin menjadi pusat perhatian sebagai bentuk investasi yang menarik bagi para pelaku pasar. Bitcoin (BTC) sering kali ditandai dengan tingkat volatilitas yang tinggi dan harganya menunjukkan kenaikan dan penurunan yang ekstrem dalam jangka waktu yang singkat. Dengan menganalisis tweet pengguna media sosial X, penelitian ini bertujuan untuk meneliti hubungan antara sentimen yang diungkapkan oleh pengguna media sosial X dan perubahan harga bitcoin. Data set yang digunakan dalam penelitian ini yaitu dataset pelatihan model yang terdapat di laman Kaggle dan dataset pengujian yang dikumpulkan dari tweet media sosial X berdasarkan tanggal terjadinya golden cross dan death cross. Data set akan melalui teknik preprocessing data, klasifikasi sentimen positif, negatif, dan netral menggunakan VADER. Pembangunan model menggunakan algoritma naïve bayes dan support vector machine. Hasil penelitian ini memperoleh model support vector machine memiliki kinerja terbaik terhadap keakuratan model dalam klasifikasi sentimen dengan accuracy sebesar 95.92%, ketepatan model dalam memprediksi nilai positif dengan tingkat precision sebesar 95.89%, tingkat usaha dalam menemukan informasi kembali dengan tingkat recall sebesar 95.92%, dan presentasi nilai bobot dari nilai precision dengan nilai recall pada f1-score sebesar 95.89%. Akan tetapi, dalam memprediksi sentimen lima dataset pengujian yang diberikan menggunakan model yang telah dilatih ditemukan algoritma naïve bayes memiliki persentase lebih tinggi yaitu 80% dalam memperoleh hasil yang sesuai antara sentimen positif untuk kondisi golden cross dan sentimen negatif untuk kondisi death cross. Social media X is a data warehouse that can be utilized to gain insight into public sentiment and its potential impact on cryptocurrency prices. In recent years, Bitcoin has become the center of attention as an attractive form of investment for market players. Bitcoin (BTC) is often characterized by high levels of volatility and its price exhibits extreme rises and falls over short periods of time. By analyzing the tweets of social media user X, this study aims to examine the relationship between the sentiment expressed by social media user X and changes in Bitcoin prices. The dataset used in this research is the model training dataset found on the Kaggle page and the testing dataset collected from X's social media tweets based on the dates of the golden cross and death cross. The dataset will go through data preprocessing techniques, classifying positive, negative and neutral sentiment using VADER. Model construction uses the Naïve Bayes algorithm and Support Vector Machine. The results of this research show that the Support Vector Machine model has the best performance regarding model accuracy in sentiment classification with an accuracy of 95.92%, model accuracy in predicting positive values with a precision level of 95.89%, level of effort in finding information again with a recall rate of 95.92%, and presentation of the weighted value of the precision value with the recall value on the f1-score of 95.89%. However, in predicting the sentiment of the five test datasets provided using the trained model, it was found that the Naïve Bayes algorithm had a higher percentage, namely 80%, in obtaining results that matched positive sentiment for the golden cross condition and negative sentiment for the death cross condition.

Di era digital saat ini, Website sangat penting bagi organisasi atau perusahaan. Namun, semakin banyak pengunjung pada Website, semakin besar beban server. Ini dapat membuat server menjadi lambat atau down. Solusi untuk masalah ini adalah load balancing. Haproxy adalah perangkat lunak open-source yang bisa digunakan sebagai load Balancer. Monitoring platform yang digunakan dalam penelitian ini adalah Grafana yang memantau sumber daya server secara real-Time dan menyediakan visualisasi data yang mudah dipahami. Tujuan penelitian ini adalah menganalisis kinerja pada load balancing Web server, memberikan gambaran kinerja Haproxy sebagai load balancing dalam menangani beban berat pada Web server, dan memberikan solusi alternatif untuk meningkatkan kinerja Web server. Tahapan dalam penelitian ini peneliti melakukan analisis kebutuhan, perancangan topologi, implementasi, dan pengujian Web server menggunakan Apache JMeter. Penelitian ini menggunakan Apache JMeter untuk menguji keandalan dan stabilitas Web server saat menangani lonjakan permintaan yang besar pada skenario single server dan Load balancing. Peneliti melakukan pengujian kinerja load balancing Web server dengan beberapa parameter yaitu throughput, Response Time, error rate, memory utilization, dan CPU utilization. Berdasarkan analisis dan penelitian yang dilakukan tentang kinerja load balancing pada Web server menggunakan HAProxy dan integrasi dengan Grafana sebagai Monitoring serta notifikasi Telegram, dapat disimpulkan bahwa Grafana yang terintegrasi dengan HAProxy efektif sebagai alat Monitoring performa Web server yang memberikan visualisasi data yang jelas dan mudah dipahami. Hal ini memudahkan proses analisis dan evaluasi performa Web server. Penggunaan load balancing juga meningkatkan ketersediaan server dalam menangani permintaan, terbukti dengan penurunan persentase kegagalan server secara drastis.
