This research aims to examine the views of contemporary Islamic law regarding bitcoin digital assets as objects of inheritance. In this research, a normative juridical method is used which involves library legal research by examining library materials or secondary data with data collection techniques using a conceptual approach. The results show that bitcoin meets the criteria to be used as inherited property because the nature of bitcoin assets is in accordance with the nature of property, but contemporary Islamic scholars differ in opinion regarding the law of using bitcoin, the Indonesian Ulema Council itself forbids bitcoin as a currency and commodity without underlying, and legalizes bitcoin as a commodity with underlying, so that the law of inheritance also depends on the opinion or fatwa that is trusted, because fatwa is not binding.

Electronic Bill (E-Bill) is a rucial negotiable instrument in the form of data messages, relying on the Electronic Bill System (EB System). Blockchain technology offers inherent data sharing capabilities, so it is increasingly being adopted by small and medium-sized enterprises (SMEs) in the supply chain to build EB systems. However, the blockchain-based E-Bill still face significant challenges: the E-Bill is difficult to split, like non-fungible tokens (NFTs), and sensitive information such as amounts always be exposed on the blockchain. Therefore, to address these issues, we propose a novel data structure called Reverse-HashTree for Re-storing transactions in blockchain. In addition, we employ a variant of the Paillier public-key cryptosystem to ensure transaction validity without decryption, thus preserving privacy. Building upon these innovations, we designed BillChain, an EB system that enhances supply chain finance by providing privacy-preserving and splitting-enabled E-Bills on the blockchain. This work offers a comprehensive and innovative solution to the challenges faced by E-Bills applied in blockchain in the context of supply chain finance.

Blockchain merupakan teknologi buku besar yang bersifat decentralized. Blockchain memiliki protokol consensus sebagai kesepakatan bersama dalam pengelolaan basis data. Contoh penerapan blockchain yaitu ethereum. Kelebihan ethereum yaitu dapat menjalankan program atau aturan yang disebut sebagai smart contract. Proses perubahan data pada ethereum memerlukan biaya transaksi atau gas fee. Nilai gas fee ini fluktuatif menyesuaikan gas fee terendah saat ini, kepadatan jaringan dan kompleksitas transaksi. Smart contract ethereum tidak efisien untuk menyimpan data yang berukuran besar karena semakin besar data yang disimpan maka semakin kompleks transaksi yang perlu dilakukan. Untuk meningkatkan efisiensi gas fee smart contract maka dilakukan sebuah penelitian dengan menerapkan InterPlanetary File System (IPFS). Teknik yang digunakan yaitu mengkombinasikan teknologi IPFS dengan smart contract ethereum untuk mengurangi kompleksitas transaksi ketika proses penyimpanan data penggalangan dana ke smart contract ethereum. Penerapan IPFS pada aplikasi penggalangan dana membutuhkan gas fee 0,00311847-0,003379868 ETH dengan kecepatan transaksi 12-36 detik. Berdasarkan pengujian sebanyak 40 kali dengan data yang berbeda, penerapan IPFS dapat menurunkan gas fee dengan rata-rata hingga 94,39% dan kecepatan transaksi sistem yang menerapkan IPFS lebih besar 13,55% dari sistem yang tidak menerapkan IPFS.

Nowadays, Learning Management Systems (LMS) have become increasingly popular, particularly due to the COVID-19 pandemic, offering enhanced effectiveness and efficiency. Online exams have emerged as a critical feature within LMS, serving as a means to evaluate students’ performance and assess their understanding of the course material. These exams play a crucial role in determining students’ eligibility for progression to the next grade or level of study. It is imperative that online exam results meet the standards of reliability and transparency. Any lack of reliability, such as the vulnerability to hacking, can have detrimental effects on students’ overall grades. Traditional online exam systems typically store data in centralized locations like MySQL databases, leaving them susceptible to unauthorized access by malicious individuals who may alter students’ exam results. This paper aims to propose a blockchain-based framework that facilitates the secure and peer-to-peer conduct and evaluation of academic exams. The framework employs hashing techniques to ensure the integrity of the data and utilizes proof of stake mechanisms to enhance security. Blockchain technology has proven to be effective in safeguarding data integrity by virtue of its decentralized data storage approach and the use of cryptographic hashing for every block within the chain. This paper demonstrates how online exams can be developed using blockchain technology, with each question asked and answered being directly stored on the blockchain. To achieve this, we have developed a module that integrates with the Moodle learning management system. Through a comparative analysis of the default centralized storage approach in Moodle, our module modifies the exam results’ storage method, ensuring secure and tamper-proof data storage on the blockchain network. By leveraging the blockchain network, the data associated with exam results is reliably secured, ensuring its integrity, and making it immune to manipulation. Our results indicate that the data stored through the blockchain achieved complete accuracy, with no discrepancies observed when compared to the standard approach employed by the Moodle LMS for storing results. The blockchain network provides a reliable and immutable platform that prevents unauthorized alterations or manipulations of student data. In conclusion, our blockchain-based framework offers a robust solution for enhancing the security and reliability of online exam results. By leveraging the decentralized and tamper-proof nature of blockchain technology, we can ensure the integrity and transparency of student data, ultimately providing a more trustworthy and accurate assessment of their academic performance.

\n\t\n\t\t\n\t\t\t\n\t\t\tWith the rapid development of technology and the large amount of digitization in various fields of human life, it is necessary to pay attention to the security and certainty of privacy so that there is no leakage of confidential data, both in the private and governmental domains, especially in Indonesia. In this case cyber-attacks will grow and become more numerous; therefore we need a security principle that can prevent these cyber-attacks, especially in sending something that is sensitive which can be called cryptography. One of the applications that can be implemented regarding this cryptography is the Whatsapp application. WhatsApp claims that the application is safe from data theft and messages being intercepted. However, this is doubtful with the presence of Whatsapp Mod which offers more features than the official application. The security of the modified Whatsapp is questionable, so in this study a test was carried out using the MobSF Framework to find out whether there were security holes that could endanger its users. The results of this research are in the form of a report issued by MobSF regarding the level of danger of the Whatsapp Mod Application. With this research, it is hoped that it will be able to make Whatsapp Mod users aware of the dangers of modified applications and Whatsapp can provide advice and strict action against the Whatsapp Mod developers.\n\t\t\t\n\t\t\n\t\n

Countries are using various sophisticated information technologies to help provide quality and transparent services. This research aims to explore the potential and models of using blockchain technology to overcome corruption problems in Indonesia. Proper utilisation of blockchain technology can increase accountability and reduce loopholes in corrupt practices. Blockchain is a distributed database with records (ledgers) shared by all network participants. Smart contract as a form of blockchain can help make the process more transparent and trackable. Since blockchain is a relatively new technology, very few studies have been done to explain its potential in the public sector, particularly with regards to issues of corruption. This study develops a model for the application of blockchain technology and conducts an in-depth analysis of its possibilities using a qualitative method and an exploratory approach. In-depth interviews, designed to get a big picture view of the blockchain development model in the public sector were conducted with several sources, namely the Director General of Asset Tracing KPK (Indonesian Anti-Corruption Commission), KPK Public Prosecutors, the KPK IT department, WIr Group, Financial and Development Oversight Agency (BPKP), and blockchain practitioners. The research was conducted between August and December 2022. The study's findings demonstrate how promising it is to use blockchain technology to lessen corruption. Distributed ledgers give governments new ways to improve transparency. The model that can be applied is ‘permissioned blockchain’ because it has a private nature. Blockchain application requires top management support, organisational readiness, and organisational support. To deepen understanding, further experimental research is needed to test the model.
