Technological developments are increasingly sophisticated where every day, these developments have directions and goals to make it easier for humans in all things. In society 5.0, technology is judged not only by its intelligence but also by its benefits in helping humans. In a company, documents are precious objects, so that various things are very concerning, such as ratification, storage, and sharing of documents. 2 (two) problems were identified, namely that many companies still use the manual method where documents must be printed to be ratified by meeting directly and conventionally storing printed documents, so it is considered ineffective and efficient. These problems can be overcome with a Software as a Service (SaaS)-based digital signature system with distributed Blockchain support, making it easier for companies to validate and store documents. By using the SDLC waterfall development method and six literature studies. Researchers hope that digital signatures make it easier for everyone to validate digitally without having to print documents and do not need to think about the validity of the digital documents so that they can be considered effective and efficient to facilitate work.
Medical records are very important and provide benefits that are felt by patients, doctors and other health workers in terms of clinical decision making. Seeing the importance of the presence of medical records, Indonesia has also implemented innovation in the use of technology in the application of digital medical records.

Blockchain technology has become a trend in various sectors, both industrial and public sectors. There have been many questions regarding this blockchain technology in terms of competition in the public sector. Mainly among these are the concerns that become issues around governance and control in distributed ledgers. From an information security point of view this article investigates the influence of blockchain technology on public domain processes. It contains an outline of the development of the provision of public services and one-way information by the government to the community, the exchange of information and communication between the public and the government through the current blockchain application, and the current development of blockchain technology. We use a triad, Confidentiality-Integrity-Accessibility to guide our discussion of the interrelationships of security, operation, and regulation of this generation. By leveraging the triad model, we offer a framework for public managers who may also be able to recommend blockchain technology, and we observe the positive benefits that arise from the denial of a distributed ledger. In particular, we look at the benefits of blockchain technology which has to do with disclaimers to help public managers understand how to leverage blockchain generation for an application process.
Technological developments continue to encourage the creation of various innovations in almost all aspects of human life. One of the innovations that is becoming a worldwide phenomenon today is the presence of cryptocurrency as a digital currency that is able to replace the role of conventional currency as a means of payment. Currently, the number of cryptocurrency investors in Indonesia has reached 4.45 million people as of March 2021, an increase of 78% compared to the end of the previous year. Very volatile price movements make cryptocurrency investments considered speculative so the risks faced are also very high. The purpose of this study is to build a predictive model that is able to forecast prices on the cryptocurrency market. The algorithm used to build the prediction model is Long Short Term Memory (LSTM). LSTM is the development of the Recurrent Neural Network (RNN) algorithm to overcome problems in the RNN in managing data for a long period. LSTM is considered superior to other algorithms in managing time series data. The data in this study were taken from the Yahoo Finance website using the Pandas Datareader library through Google Collaboratory. The entire prediction model development process is carried out through Google Collaboratory tools. To improve the accuracy of the model, the Nadam optimization algorithm was used and three testing sessions were carried out with the number of Epochs of 1, 10, and 20 in each session. The final test results show that the best prediction performance occurs when testing the DOGE coin type with the number of Epoch 20 which gets an RMSE value of 0.0630.

Technological evolution has contributed to considerable changes in the learning methods used today. If a few years ago, before the technological boom, students relied only on their memory capacity, on notes on sheets of paper and written materials (in the form of course materials, books, or textbooks), today the process of learning is significantly facilitated by the means and techniques involved in the use of technology, such as artificial intelligence, smartphones, and tablets, which are rapidly replacing bulky desktop computers and outdated textbooks used in the learning process. Moreover, blockchain technology can also be used as a motivational factor for developing learning abilities by implementing a system that can bring students credit points convertible into cryptocurrencies or online badges. Studies conducted in the field show that studentsโ motivation for learning and creativity is significantly improved with the help of this reward system. In this article, two specialized studies were conducted (in Romania), one on the perception of teachers in the university environment towards the use of new technologies in the learning process (artificial intelligence, smartphones, and tablets), and the other on the perception of students on the technological integration of blockchain (by implementing a system that can bring students credit points convertible into cryptocurrencies or online badges to certify their knowledge) in the learning process and measuring their satisfaction.
Voting is arguably the most important as well as elementary right in democracy that has existed for the past hundreds of years; it has taken place in the context of a large- and small-scale community. The process transitioned from paper ballots to electronic voting machines (EVM) in the late 20th century, but even with all the advancement, transparency in the election process remained the same. Blockchain technology came in existence in 2008 with the introduction of Bitcoin by Satoshi Nakamoto, and in the last decade we saw enormous growth in development and execution of this technology in various fields e-voting is one of them, blockchain-based e-voting system has potential to improve the election process if utilized to its potential. Blockchain can eliminate the need to print ballot paper as it is secure, immutable and convenient to voters and can make elections more transparent.

Objective: Managing training certificates is an important issue in research that can lead to serious issues if not addressed properly. For institutions that currently do not have a dedicated management system for these training certificates, a central database is the most typical solution. However, such a system suffers from several risks, such as a single-point-of-failure. Materials and Methods: To address this issue, we developed and evaluated CertificateChain, a decentralized training certificate management system by using peer-to-peer blockchain and automated smart contracts. We developed an efficient certificate dividing-and-merging algorithm to overcome the transaction size limit on blockchain. Results: We performed experiments on the system to evaluate its performance, then created a web app and tested the system in a real-world scenario. CertificateChain scaled linearly in terms of time compared with the total number of certificates added and could be quickly queried for existing data stored on-chain. Discussion: CertificateChain was able to store and retrieve the training certificates on the blockchain network, with limitations including a comparative analysis of other systems, evaluation of different consensus protocols, examining certificates off-chain, a thorough comparison with a centralized system, and the extension to the main public Ethereum network. Conclusion: We believe that these results indicate that blockchain technology could be a viable decentralized alternative to traditional databases in this use case.

Cryptocurrency is a blockchain-based technology that is often used as a digital currency. Digital money is different from conventional money, this type of money does not have a physical form but only a block of data bound by a hash as validation. The data is spread to every cryptocurrency user who is in the environment. So that when a user makes a transaction, data mining will be carried out. Cryptocurrencies have several advantages but also have disadvantages when used as currency, from a legal point of view there is still no law governing the circulation of currency in digital form (cryptocurrency). The government must recognize digital currency so that it can be accepted by the general public as a means of payment. For now, the government has not recognized digital money (cryptocurrency) as a currency, because Cryptocurrency is a new phenomenon by some people in Indonesia. The rapid development of technology in the 4.0 revolution era, in the next few years money in physical form will be replaced by digital money, seeing the many conveniences provided by using digital money.
The revolution in a technology certainly provides new innovations that are more creative and effective than previous technologies where the technology is called a ledger (blockchain technology). Blockchain technology is known as bitcoin or digital currency that can be used anywhere without a third party when making a transaction. The development of blockchain technology used in crypto has been applied in the field of education. The system contained in blockchain technology has a data center with distribution that will be distributed in each computer network to serve as a data base or data center that contains information in digital form. However, the popularity of blockchain technology is still many who do not know what blockchain technology can provide for education in today's digital age, for this reason this research paper aims to inform that there are several benefits that will be received in the field of education from the application of blockchain technology. The use of blockchain technology has become global so that more information is needed in providing concrete examples that have obtained the results of implementing blockchain technology so that Indonesian education can compete in the world because it does not lag behind the use of technology in education as a place for data storage and security. Literature review is the method of this research by looking for previous research that has been published with the same theme. And this research uses the slovin method, which is a calculation method. This research paper encourages further researchers to be able to provide education about blockchain technology in national and international forums...
The era of rapid disruption was accompanied by increased crime in data falsification and interception. The philosophy of Blockchain technology is related to its ontology; it can be characterized, applied, and realized by how it works in the world of education. Blockchain technology is used to verify the authenticity of academic degrees and certificates. Systems that use digital signature schemes and implementation timestamps in the development of blockchain technology use blockchain software. The impact of falsifying educational documents results in workers not being qualified for a particular position. The main interest of this service is to balance between graduates and employers by minimizing crime and falsifying educational documents. The method used in this research is a literature study from previous studies. As a result of maximizing the potential of blockchain technology, fees can also lead to checking the authenticity of certificates through trusted sources. The application and utilization of blockchain in the academy certificate fraud detection system can be a means of offering problems that exist from a global perspective and other stakeholders.
