In a digital communication environment, information security is mandatory. Three essential parameters used in the design process of a steganography algorithm are Payload, security, and fidelity. However, several methods are implemented in information hiding, such as Least Significant Bit (LBS), Discrete Wavelet Transform, Masking, and Discrete Cosine Transform. The paper aims to investigate novel steganography techniques based on agent technology. It proposes a Framework of Steganography based on agent for secret communication using LSB. The most common image steganography databases are (...) explored for training and testing. The methodology in this work is based on the statistical properties of the developed agent software using Matlab. The experiment design is based on six statistical feature measures, including Histogram, Mean, Standard deviation, Entropy, Variance and Energy. For steganography, an Ensemble classifier is used to test two scenarios: embedding a single language message and inserting bilingual messages. ROC Curve represents the evaluation metrics. The result shows that the designed agent-based system with 50% training/testing sample set and 0.2 Payload can pick out the best cover image for the provided hidden message size to avoid visual artifact.

Blockchain is one of the technologies that can support digital transformation in industries in many aspects. This sophisticated technology can provide a decentralized, transparent, and secure environment for organizations and businesses. This review article discusses the adoption of blockchain in the ports and shipping industry to support digital transformation. It also explores the integration of this technology into the current ports and shipping ecosystem. Besides, the study highlighted the situation of the supply chains management in ports and shipping domain as (...) a case study in this field. The investigated studies show that blockchain can be integrated into processes such as financial and document workflow. This review contributes to research by focusing on the adoption of blockchain in the ports and shipping industry to support digital transformation. It also aims to understand the existing port practice and map it with current tendencies based on blockchain. This study gives insight analysis to incorporate blockchain technology into ports and shipping processes globally. (shrink)

This study elaborated on the explanation of theosophical Sufism in the book of al-Hikam by two well-known Islamic academics, Kyai Sholeh Darat (Indonesia) and Shaykh ‘Abdullah Gangohi (India). The data in this study are the text of Syarah al-Hikam, written by Kyai Sholeh Darat and the text of Syarah Al-Hikam in the perspective of Shaykh ‘Abdullah Gangohi. This qualitative research study used a Systemic Functional Linguistic (SFL) approach from M.A.K. Halliday. Data analysis in this research applied the Spradley (...) model, namely: (1) domain analysis, (2) taxonomy analysis, (3) componential analysis and (4) analysis of cultural themes. The domain analysis tried to map the information structure in the explanation of al-Hikam based on the theory of SFL. This information structure is the basis for the genre analysis as a semiotic representation of social society. Meanwhile, the taxonomic analysis tried to elaborate on the Sufism thoughts of both the thinkers based on the Syarah al-Hikam text. Componential analysis synergised the results of the information structure and the theosophical Sufism thought in al-Hikam. Finally, the analysis of cultural themes endeavoured to elaborate on the theosophical Sufism thoughts of the two Sufism thinkers and to draw the relationships and the contributions to the universal Sufism. The conditions of theosophical Sufism can be elaborated based on the information structure. The limitation of this study is the lack of researcher’s efforts to investigate the substance of theosophical Sufism, because this research is only limited to the outer layer of language.Contribution: This article shows that the thought of theosophical Sufism showed that Islam in Southeast Asia is Islam that carries the spirit of Islam Rahmatan lil-alamin. In addition, the thought of theosophical Sufism in Syarah al-Hikam has had an impact on the socio-cultural transformation, especially on the Sufism movement [thariqah] spread across Indonesia and India.
