Abstract

 Today, elections are one of the foremost important means of sustaining democracies. thanks to the opportunities brought by technology, the need of creating the elections within the physical environment is decreasing every day. Instead, the difficulty of creating elections within the electronic environment is becoming more and more popular. With the emergence of Blockchain technology, the safety of the elections within the electronic environment has also been ensured to an excellent extent. On the opposite hand, moving the election system to the electronic environment will eliminate the physical costs, make sure the election security within the authoritarian regimes by eliminating the central authority through blockchain, and increase the participation rates within the elections because people can vote from anywhere with internet access. one of the foremost important elements within the blockchain-based electoral system is that the connection between the voter and therefore the vote, in other words, user privacy. during this article, we might wish to introduce an idea of blockchain- based voting systems

Abstract

During the COVID-19 pandemic, many attempts have been made to predict cases of additional patients, deaths and other medical indicators using various methods. Several forecast projects and predictions have influenced policies in several countries, including Indonesia. However, predictions and predictions for the COVID-19 pandemic are inherently uncertain. Uncertainty is rooted in a lot of the unknown. Starting from the virus itself, complexity, heterogeneity, human behavior, protocols and government intervention. In this study we explored the potential using the term "Predictive Monitoring" using the SIR method and statistical models. This method was chosen because it is one of the basic methods in epidemiological models. The purpose of this research is to capture and understand changes that occur as meaningful signals of uncertainty over changes in actual scenarios. The results of predictive monitoring obtained from this study amounted to 0.89 or 89% for the cure rate and 0.64 or 64% for the mortality rate. With this signal, it is hoped that the planning, behavior and mentality of the current community will become more forward-looking in initiating and guiding preventive actions to shape the real future. Keywords—Data Science, Forecasting, Model SIR, COVID-19

Abstract

Perkembangan teknologi blockchain, khususnya Ethereum, telah membuka peluang besar dalam pengelolaan data dan transaksi di berbagai sistem bisnis melalui penerapan smart contract. Blockchain menawarkan potensi besar dalam hal desentralisasi dan keamanan data, yang menjadi keuntungan utama dibandingkan dengan sistem database relasional tradisional. Namun, meskipun blockchain memiliki banyak keunggulan, efektivitas teknologi ini dalam hal kinerja, terutama dalam pengolahan transaksi bisnis, masih perlu dievaluasi lebih mendalam. Penelitian ini bertujuan untuk menguji dan membandingkan kinerja private blockchain berbasis Ethereum dengan database relasional MySQL, dengan fokus pada pengolahan transaksi bisnis yang melibatkan berbagai parameter kinerja. Pengujian dilakukan dengan mengukur waktu respons transaksi, throughput, dan kapasitas data maksimum per transaksi pada kedua platform. Setiap platform diuji menggunakan enam node blockchain pribadi dan sistem MySQL yang terkonfigurasi secara serupa. Hasil pengujian menunjukkan bahwa meskipun blockchain menawarkan keunggulan dalam aspek keamanan dan desentralisasi, database relasional lebih unggul dalam hal kecepatan pemrosesan dan kapasitas data transaksi. Private blockchain mampu menangani transaksi hingga 6.688 byte dengan waktu respons rata-rata 2.027 ms, sementara MySQL mampu memproses hingga 65.535 byte dengan waktu respons hanya 1,22 ms. Temuan ini menunjukkan bahwa integrasi blockchain dan database relasional dapat menjadi solusi optimal untuk menggabungkan kelebihan keduanya dalam meningkatkan performa dan keamanan sistem bisnis modern. Penelitian ini berkontribusi dalam pengembangan arsitektur sistem yang memanfaatkan kelebihan kedua teknologi tersebut secara bersamaan, sehingga dapat menciptakan sistem yang lebih efisien, aman, dan skalabel.
