An innovation that was sparked is an alternative currency to replace conventional currency, namely digital currency that is secured using a cryptographic method called Cryptocurrency. However, cryptocurrency prices cannot be controlled, causing massive fluctuations. Cryptocurrency price changes are very stable due to several factors such as speculation from users and the nature of the follow-up from new to one of the causes. The cause of this bandwagon is due to extreme price increases in a short time, even within a day the price of Crypto can experience a difference of millions of rupiah for each increase and decrease. To answer this question, we need a software that can predict the Rupiah exchange rate. By using the Triple Exponential Smoothing prediction method. In implementing Triple Exponential Smoothing, historical data is needed which will later be processed to produce prediction results, for that we need parameters that can be used as historical data counters, in this study used parameters 0.40 as parameters Xt and S't and 0.60 as Beta parameters. In the process, starting from calculating the first to third smoothing, ensuring Constants, Slopes, and Parabolics, to completing the process by producing Forecasting, the results of the measurement of the margin error level with a margin of error of 0.94638% using data for the final 2021 period, which is between November - December on the Triple Exponential implementation simulation and on the implementation into the system that has been developed is 3.7249% using data from May 2022 to June 2022.

Introduction: A lot of hospital management systems, especially open-source ones, still lack interoperability which is holding back the effectiveness of administration. This happens due to different regulations from hospital organizations. Therefore, there must be a system that facilitates interoperability. Blockchain is a decentralized ledger system, to insert the data from the blockchain all parties must agree that the data is valid thus the data can be inserted so, all the data are immutable thus every change can be audited. Methods: We integrate the Hyperledger fabric network, an open-source modular blockchain platform, into an open-source hospital management system, openEMR. We take the changed data using debezium connect and Kafka and inserted it into the blockchain. Results: Based on our test, we managed to get average read latency at 27ms, average read throughput at 36 Read per Second, average transaction latency at 45ms, average transaction throughput at 22 Transaction per Second, and average integrated system data transfer at 111.36ms. Conclusions: All services deployed successfully at the Kubernetes without any error. All services work as they should be. One service can integrate through the internal network of the Kubernetes and from the outside cluster using ingress. OpenEMR can be used normally as indicated in the official documentation and the data change is stored in the blockchain.
Non-Fungible Token (NFT) is a blockchain-based token that securely maps copyright ownership to digital assets, these digital assets exist on the blockchain network which have identification codes and metadata that are unique and different from each other (one-of-the-kind). . It can also be interpreted as a digital asset that represents a variety of assets that are considered unique. NFTs can be traded for digital assets (images, music, videos, virtual creations) where ownership is recorded in a smart contract on the blockchain. One of the difficulties faced is that it takes a very long time for NFT creators to create a large number of works of art in a short time. To make it easier for creators to create NFT images, Daniel Eugene Botha, or better known as Hashlips, created a Hashlips Art Engine algorithm that can be used to create many different NFT images based on the layers provided using the canvas API and node.js. The hashlips algorithm also generates metadata as an important role in the mechanism for searching and exchanging NFT data and measuring the percentage of rarity in the resulting image. In addition, this study also shows the time required to create NFT images.
Accounting is part of the information system of a company that generates the most important information for the decision-making process. This process should be supported by new technologies to respond to all business requirements. Disruptive technologies change the way of performing business transactions and their implementation in business practice was notably accelerated by the pandemic. In this context, Blockchain technology has been articulated as the future of the accounting profession and there is a growing body of research regarding the impact of the blockchain on accounting practice and the accountancy profession. Many advantages arise from blockchain technology's distinctiveness, but also many risks that need special attention. Consequently, evolving conditions require professional accountants around the world to master new skills related to emerging information technologies. Being accustomed to information technologies is one of the basic prerequisites for the quality service that professional accountants offer to clients. Accounting education, especially at universities, has an important role in forming competent professional accountants and enabling required skills that are an essential part of professional competence. Accounting education has a challenging role in this context to incorporate and transfer knowledge regarding new technologies. This paper aims to analyse the recent research to investigate the impact of blockchain technology on accounting practice. The paper also focuses on the analyses of means of the inclusion of blockchain technology into accounting education and curriculum, by conducting a literature review of relevant sources. Research findings enable further understanding of the implications of blockchain technology in the accounting context, both for accounting practice and accounting education. Results can serve accounting educators since this topic is not sufficiently explored and needs further analysis.

The existence of the Covid-19 virus, which was first announced at the end of 2019, in a short time was able to cause a pandemic. To overcome this, the government implemented a protocol that integrates Covid-19 test results and vaccination certificates into an application, with the aim that individuals can prove that they are free from Covid-19 infection and can return to normal activities. However, a centralized system is prone to single point of failure and data manipulation from the intervention of certain parties due to a lack of transparency. This paper proposed the use of Ethereum blockchain and smart contracts to solve this problem. By Using blockchain technology and smart contracts, the data management process will be more transparent since every transaction on the blockchain is recorded by each node. Blockchain also prevents a single point of failure because there are more than one data providers. The system that has been developed has fulfilled the security and privacy aspects of patient data by implementing password-based encryption on patient data. However, the system’s response time is strongly influenced by the computational capabilities of the Rinkeby network. On average, the system took 47,9 seconds to register a new certificate.
Bitcoin merupakan salah satu aset kripto yang biasa digunakan untuk bertransaksi secara virtual dan merupakan tiga teratas dari cryptocurrency yang paling banyak diperdagangkan. Harga bitcoin dapat berubah setiap waktu, untuk itu diperlukan suatu prediksi harga bitcoin dimasa mendatang. Penelitian ini bertujuan untuk menerapkan aplikasi orange data mining dalam memprediski harga bitcoin dengan metode K-Nearest Neighbor (K-NN) dan Support Vector Machine (SVM). Prediksi kinerja dari kedua metode yang digunakan dapat dilihat dari hasil Root Mean Square Error (RMSE) dan Mean Absolute Error (MAE). Data bitcoin yang telah dikumpulkan akan dianalisa menggunakan aplikasi orange data mining, proses pengujian menerapkan K-Fold Cross Validation (K=5), sedangkan proses perbandingan metode menggunakan Test and Score. Hasil perbandingan kedua model menunjukkan bahwa SVM karena memiliki nilai RMSE dan MAE paling kecil yaitu 0.010 dan 0.008, maka dari itu untuk prediksi harga bitcoin di masa mendatang model Support Vector Machine (SVM) dapat dijadikan rekomendasi terbaik dibandingkan model K-NN.
The study aims to determine the effect of awareness of business students towards cryptocurrencies and readiness of universities and colleges to accept cryptocurrencies as a medium of exchange considering the mediation of business students’ attitude. The research used partial least squares structural equation modeling (PLS-SEM) and deployed a questionnaire attuned to the awareness and attitudes of business students towards cryptocurrencies and readiness and compatibility of use to universities and colleges in Ilocos Norte. The output of the investigation revealed that awareness of business students are not correlated to readiness of universities and colleges which means that even though students understand cryptocurrencies, it is not an assurance that universities and colleges are ready to accept it as medium of exchange. The study proposes that trainings and seminars for business students and professionals should be conducted to expand understanding and acceptance of cryptocurrencies.

Cryptocurrencies are now the most popular investment instruments among millenials. Crypto offers great returns in a short period of time. Prior to COVID-19, Crypto experienced significant price fluctuations accompanied by an increase in the number of high transaction volumes. This situation was disrupted by the presence of the COVID-19 which made the world economy devastated, marked by the decline of stock prices in the world, especially in Indonesia. A paired test was conducted in this study to compare the state of Crypto before and during COVID-19 with the variables of Risk, Transaction Volume, Return, and Sharpe Performance. The results showed that there was a significant difference in the variables of Transaction Volume and Return. However, there was no significant difference in the Risk and Sharpe performance before and during COVID-19. This study shows that despite the COVID-19 pandemic, the enthusiasm of investors who transact crypto assets is not affected and they still get returns in accordance with the investments made. The high risk will be followed by a high standard deviation, so that the Sharpe Performance is small. Cryptocurrencies still have many gaps to research, such as regulation, so that many countries have not legalized Crypto transactions. If there is no regulation for Crypto, it is certain that an increase in cybercrime harms crypto investors and threatens global financial stability. Nevertheles, with or without COVID-19, investment transactions gain and lose based on confidence in the limited market. Therefore, the success of confidence fluctuations in crypto encourages the emergence of alternative coins created by investors to conduct an Initial Coin Offering (ICO).
