Contemporary, Indonesia is looking for an innovative solution to securing diploma certificate and transcript from forgery. Several cases had been reported due to the usage of a fake transcript. One modus of using fake transcript is to enter a higher level of education and job promotion. The new technology found called Blockchain believes in solving the problem. Characteristics of Blockchain Technology such as secured, immutable, distributed, transparent seem to be matched with transcript document requirement. Therefore, the research tries to create a process model of the university teaching and learning process. Several studies have been done; however, no detailed process shown especially for teaching and learning activities. The research question is, how are teaching, and learning activities can be supported by Blockchain Technology? Qualitative method used in this research, focus group discussion with 9 reputable universities discussed the academic operation process and the result show that it is possible to adopt Blockchain Technology into the teaching and learning process to avoid forgery of university transcript documents.

The increasing of digital technology today has helped many people to fulfill their needs. But the election system, still conventionally using paper in its implementation. Elections in general still use a centralized system, where there is an organization that manages it. Some of the problems that may occur in traditional electoral systems are that there are organizations that have full control over the database and system, so the possibility of hacking the database is quite a big opportunity.Blockchain innovation is one arrangement that can be utilized in light of the fact that it has a decentralized framework and the whole database is duplicated by all clients. Blockchain itself has been used by Bitcoin and Ethereum cryptocurrency which is known as a decentralized system. By using the blockchain in database recording on an e-voting system can reduce one source of fraud that is database manipulation. This study discusses the recording of voting data using blockchain technology. The implementation of Smart Contracts contained in the Ethereum Blockchain will be implemented to create this voting system

A trusted achievement record is a secure system that aims to record and authenticate certificates as well as key learning activities and achievements. This paper intends to gather important information on the thoughts and outlooks of stakeholders on an achievement record system that uses blockchain and smart contract technology. The system would allow stakeholders (for example employers) to validate learning records. Two main aims are investigated. The first is to evaluate the suitability of the idea of building a trusted achievement record for learners in higher education, and to evaluate potential user knowledge of blockchain technology. This is to ensure that a designed system is usable. The second aim includes an interview conducted with a small group of participants to gather information about the challenges individuals have when creating, and reviewing CVs. Overall, 90% of participants agreed that there was a strong need for a trusted achievement record. In addition, 93.64% of respondents stated that they felt it was invaluable to have a system that is usable by all stakeholders. When tackling the second aim it was found that a primary challenge is lack of knowledge of blockchain and its complexity. From the employers' perspective, there is a lack of trust due to inaccuracies when students describe skills and qualifications in their resumes.
Conventional certificate verification, whether paper-based or backed by a centralized digital registry, remains exposed to forgery, single points of failure, and slow manual cross-checking between issuers, holders, and verifiers. This paper presents a decentralized, blockchain-based framework for issuing, storing, and verifying academic and professional certificates that addresses these weaknesses without placing the full document on-chain. Each certificate is reduced to a SHA-256 hash, signed with the issuing institution's RSA private key, and recorded through an Ethereum smart contract, while the original file is retained off-chain on IPFS and referenced by its Content Identifier. Only institutions that pass a unanimous, vote-based onboarding process administered by a validator consortium are permitted to issue certificates, which constrains the system to a trusted-issuer model while preserving decentralization across the validator set. A hash-mapped Bloom Filter sits in front of the blockchain query path and performs a fast probabilistic existence check, allowing forged or non-existent certificates to be rejected before an on-chain lookup is triggered. A prototype was implemented with Solidity smart contracts on the Ethereum Sepolia testnet, a Node.js/Web3.js application layer, and a React.js frontend with MetaMask-based authentication. Evaluation on the testnet shows that the Bloom Filter pre-check lowers the average lookup time for invalid certificates by roughly 87%, keeps verification of valid certificates under two seconds end-to-end, holds the false-positive rate below 0.5% for up to 50,000 stored certificate hashes, and reduces the gas cost of issuing a certificate to approximately 4.57 USD. These results indicate that combining consortium governance, cryptographic hashing, and probabilistic filtering yields a certificate validation pipeline that is simultaneously tamper-resistant, low-cost, and fast enough for real-time institutional use.
Ijazah konvensional mempunyai beberapa kekurangan diantaranya yaitu bisa dipalsukan, membutuhkan tempat pemyimpanan yang aman dan bisa rusak. Oleh karena perlu dibuat teknologi informasi yang bisa mengatasi kekurangan tersebut, salah satunya adalah smart contract pada blockchain Ethereum. Smart contract pada blockchain Ethereum memungkinkan membuat ijazah dengan integritas dan keamanan data yang tinggi, sehingga bisa meminimalisir kerusakan dan pemalsuan ijazah. Akan tetapi blockchain Ethereum memerlukan biaya yang besar dalam menyimpan data yang besar. Pada penelitian ini bertujuan guna mengukur performa dari pengimplementasian IPFS pada smart contract yang dapat membuat biaya transaksi lebih stabil dan murah sebesar 61,95% dibandingkan dengan blockchain Ethereum tanpa mengimplementasikan IPFS. Selain itu, performa pada smart contract yang mengimplementasikan IPFS dapat meningkatkan performa dari Quality of Service (QoS) dengan parameter throughput sebesar 6,04 kali, Packet Loss 39,47%, dan Latency 42,28%.

In this paper, we report the benchmarking results of Hyperledger, a Distributed Ledger, which is the derivation Blockchain Technology. Method to evaluate Hyperledger in a limited infrastructure is developed. The measured infrastructure consists of 8 nodes with a load of up to 20000 transactions/second.. The benchmarking of Hyperledger shows better than a database system in a high workload scenario. We found that the maximum size data volume in one transaction on the Hyperledger network is around ten (10) times of MySQL. Also, the time spent on processing a single transaction in the blockchain network is 80-200 times faster than MySQL. This initial analysis can provide an overview for practitioners in making decisions about the adoption of blockchain technology in their IT systems.
The higher education system in developing countries has remained quiet unchanged for long time. Even with new and better technologies in this field has emerged tremendously; their adoption is marked extremely narrow. The connection between student and faculties is unchanged and the records are still stored and validated centrally. Block chain has introduced a fresh and novel path to decentralize the records and their exchange for gaining knowledge and skills. This paper is an attempt to understand block chain technology and its application on education. It discusses the use of block chain and the few of the many models designed to support educational bodies. The mere attempt to discuss the problem and challenges faced by block chain for successful support to education is presented in this article.
Blockchain Technology is used to develop applications more easily and maintain the information as safe and secure. This work is aimed towards developing a recruitment process supported by blockchain technology. Currently, a manual system is used to recruit employees; Manual recruitment is a time consuming, costlier non-secure process. Selection and recruiting the candidates is a vital process for an organization. The proposed method uses blockchain technology for the recruitment process. The entered candidate details are verified by the college, organization for the last workplaces, and law enforcement. Based on the approval, the candidate data is stored in a block with its transaction hash value. The transaction hash consists of the unique predefined fixed-length text of the block and it secures the data from tampering. SHA-256 is one of the hashing algorithms to develop a transaction hash. Once the candidate information is stored in the blockchain, the recruiters read the candidate data from the blockchain and select the validated candidate for the recruitment process. It ensures that they are retrieving the valid details of candidates and can proceed for the further recruitment process. The technology uses a Smart contract under the Ethereum platform to provide security for the recruitment application and tested using the Ganache tool.
Bitcoin is a cryptographic-based digital commodity, also known as virtual currency or digital currency, which is used as a means of transactions and investments. In Indonesia the use of bitcoin is not merely a matter of technology, but has entered the realm of fiqh. An interesting phenomenon related to this is the response of several Islamic organizations and also study forums at Islamic boarding schools in Indonesia in addressing the bitcoin issue. Among them is Bahtsul Masail, the Nahdlatul Ulama Regional Manager (PWNU) in East Java in 2018. According to Bahtsul Masail's decision on the fiqh view of the use of bitcoin as a transaction and investment tool, it is legal, and may be used for muamalah. This is different from the results of the bahtsul masail in Ma'had Aly Hasyim Asy'ari Tebuireng Jombang, that bitcoin is classified as a virtual asset like dain (accounts receivable). And can be used as a legal transaction tool. But if bitcoin is used as an investment tool then the law is haram because the bitcoin exchange rate is very volatile. Based on this background, a problem arises, namely how to analyze the decision of Bahtsul Masail Ma'had Aly Hasyim Asy'ari about bitcoin and use what method to view bitcoin. The type of research used is library research. Using a normative legal approach (doctrinal), then the research is presented using descriptive techniques. In bahtsul masail using the ijtihad jama'i and ijtihad tatbiqi methods, in bahtsul masail using the term ilhaq, based on evidence, that bitcoin is equated with speculation (gambling), it is illegal.

Abstract In this day and age, access to the Internet has become very easy, thereby providing access to different educational resources posted on the cloud even easier. Open access to resources, such as research journals, publications, articles in periodicals etc. is restricted to retain their authenticity and integrity, as well as to track and record their usage in the form of citations. This gives the author of the resource his fair share of credibility in the community, but this may not be the case with open educational resources such as lecture notes, presentations, test papers, reports etc. that are produced and used internally within an organisation or multiple organisations. This calls for the need to build a system that stores a permanent and immutable repository of these resources in addition to keeping a track record of who utilises them. Keeping in view the above-mentioned problem in mind, the present research attempts to explore how a Blockchain based system called Block-ED can be used to help the educational community manage their resources in a way to avoid any unauthorised manipulations or alterations to the documents, as well as recognise how this system can provide an innovative method of giving credibility to the creator of the resource whenever it is utilised.
Blockchain is the core technology used to create cryptocurrencies, such as Bitcoin. As one part of the fourth industrial Revolution since the invention of steam engines, electricity, and information technology, blockchain technology has begun to be applied in areas such as finance, judiciary, and trade. Blockchain technology uses decentralized, distributed and transparency techniques for data security. This research aims to determine the implementation of blockchain technology in the field of education, especially in the Data Security section. The study uses two methods namely the mind mapping method and literature review. The results of this study showed that with the presence of blockchain technology, the data is more secure from attacks from both inside and outside because it passes through two levels of security, namely encryption and decentralized data.
As we know, Indonesia has begun to enter the era of revolution 4.0 which in that era there were many changes in all fields including the presence of blockchain technology which began to be in demand. Including in the field of education, the changes that occur in the world of education today are so significant with the commencement of the abandonment of teaching methods that still use conventional methods. Keep track of tasks by book, face to face communication, which of course will cause many losses in a certain period of time, as many tasks that have long been buried become difficult to find when needed, and the possibility of manipulation of tasks is still great. The learning method is considered as a boring and insecure way, where students cannot explore learning because the collected files can still be manipulated by other parties. So from now on the application of learning methods is changed by the concept of gamification which relies on blockchain technology. The gamification learning method was created to compensate for the times when students preferred to play games rather than learning, therefore the gamification method could be applied to management education in higher education.
