DIGITAL SYSTEM BLOCKCHAIN SEBAGAI STRATEGI UNTUK OPTIMALISASI PENGELOLAAN DANA ZAKAT: STUDI KONSEPTUAL

Digitalization is a new phenomenon in the early twenty-first century connecting technology with civilization and benefits mankind in an intelligent and efficient way. The adoption of the blockchain concept in zakat institutions is the time to be a solution in dealing with existing Islamic problems such as the collection and distribution of zakat funds. This study was to provide an overview of the opportunities, potential and capabilities of blockchain system adoption in zakat institutions, especially in Indonesia. The method was a literature study by reviewing various relevant literatures and balanced with related studies on phenomena in various countries. With dynamic technological developments, especially the emergence of blockchain technology, the zakat ecosystem can be further enhanced since blockchain offerred the concept of data decentralization which were permanent, real-time, secure and transparent. Several things to encourage this practice could be done by increasing the capabilities of zakat institutions' human resources, increasing awareness of compulsory zakat and the concept of digitizing zakat, integrated cooperation between OPZs, and collaborating with various digital platforms.

Digital System Design for Quantum Error Correction Codes

Quantum computing is a computer development technology that uses quantum mechanics to perform the operations of data and information. It is an advanced technology, yet the quantum channel is used to transmit the quantum information which is sensitive to the environment interaction. Quantum error correction is a hybrid between quantum mechanics and the classical theory of error-correcting codes that are concerned with the fundamental problem of communication, and/or information storage, in the presence of noise. The interruption made by the interaction makes transmission error during the quantum channel qubit. Hence, a quantum error correction code is needed to protect the qubit from errors that can be caused by decoherence and other quantum noise. In this paper, the digital system design of the quantum error correction code is discussed. Three designs used qubit codes, and nine-qubit codes were explained. The systems were designed and configured for encoding and decoding nine-qubit error correction codes. For comparison, a modified circuit is also designed by adding Hadamard gates.

ПРИНЦИПИ ПРОЕКТУВАННЯ ЛЮДИНО-МАШИННОЇ ВЗАЄМОДІЇ У ЦИФРОВОМУ СЕРЕДОВИЩІ

Modern society life is inextricably linked with the digital environment. A consequence is the transformation of ergatic systems into digital ones. The result is the emergence of new types of man-machine interaction. The essential feature of such interaction is to minimise human involvement in the ergatic system functioning. According to this, the issues of organising the safe and effective functioning of digital ergatic systems have priority importance. In this regard, the aim was to study the features of man-machine interaction in an actual digital ergatic system. We chose an ergatic system for research. The main elements of the system were students (70 people of the first-year study) and teachers (5 people) of the Simon Kuznets Kharkiv National University of Economics, as well as the digital system “Personal training systems the Simon Kuznets Kharkiv National University of Economics” (PTS). This digital system is an adapted model of the Moodle digital system. The study found out that the key components that determine the safety and efficiency of the digital ergatic system are the operator's digital mindset, digital tools and digital devices. The study of these components in the system made it possible to establish that it had a balanced state. It is substantiated the optimal form of man-machine interaction in the system. It is mixed learning. It is shown that the tendency to minimise the human role in a digital ergatic system does not always have the expected positive result, which determines the need for further research on this issue. In addition, we analysed the difficulties arising in the design of digital systems. The main reason for this is a lack of developers awareness of the ergonomic and cognitive aspects of man-machine interaction. It is shown that the development of critical thinking and intuition in students is closely related to the individual trajectory of learning. For this, it is essential to update interdisciplinary knowledge. In this case, it is necessary to familiarise students with current concepts and system-forming principles, which are the basis of human factors engineering. It was substantiated that the application of current concepts and system-forming principles in training will allow optimising man-machine interaction. The positive results will be evidence even at the stage of designing digital systems
