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.

Blockchain is a new technology in storing valid data. This study aims to minimize errors and falsification of data in the field of education that has been verified inaccurate data storage. This study uses a workflow analysis method for valid data storage verification systems. The novelty of this research is that Blockchain offers additional security of central data storage as a cryptographic network regulator to provide verification and authentication that occurs in data exchange in the network. It can be concluded that online verification of data storage has become a more modern and secure container.
Personal Health Record (PHR) is currently used as a communication platform between patients and health care providers that can be accessed at any time and must be secure. Blockchain based Ethereum that supports Smart Contracts and Decentralized Applications (DAPPS) supports secure transactions. Large medical record storage costs high on Ethereum so the Interplanetary File System (IPFS) as alternative storage is a solution to reduce costs. The built PHR function runs as follows. Users log into PHR to transact on blockchain smart contracts. When a medical record occurs, the PHR application will redirect the data storage to IPFS and return a unique hash value to the PHR application for permanent storage on the Ethereum Blockchain. The hash value used by this PHR application refers to medical records as the basis for consultations between doctors even in different hospitals based on patient authorization. In this way, interoperability between two or more different health information systems can be done safely and relatively inexpensively.

Connecting cities further into nearby supply chains worldwide is the basis of Indonesia's provincial finance progress. We analyze Indonesia's budget considerations, allocations, and Blockchain investigations. We argue that we must address the four issues of topographic access, high costs, lack of managing account items, and no education related to money to address budget embezzlement. We propose investigating selection initiation, appropriation design, and outcomes to develop this understanding. The usage of blockchain in the financial sector truly extends beyond simple cryptocurrency exchanges. The usage of blockchain in the financial sector is very broad, the Chief Executive Director of the Payment System Policy Department of Bank Indonesia (BI), who was quoted by daily social. The answers to these devotional questions will offer help to help us keep our distance better, much better, and higher Novelty of this research by improving the performance of how Blockchain-based progress is accepted in the provinces of Indonesia.

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.
