Today, a company continues its activities in a highly competitive environment regardless of the sector in which it operates. An important point has been emphasized in many developments by experienced managers and academics which have been released to the public. From marketing to finance, human resource management, auditing and planning, all business processes have entered an incredible innovative process. One of the topics in this process is big data. When cumulative data are not used, they cannot transcend being huge piles of garbage. However, it is not possible to analyze such large, complex, and dynamic data via conventional methods. At this point, the concept of big data has emerged. In this study, after the explanation and definition of the concept, a vast literature review was conducted in order to present the relationship of big data with IoT, big data-related topics, and academic researches on big data. Afterwards, real-life enterprise applications were exemplified from various industries.

The commitment of state to expand the market share of sharia bank in Indonesia become reality with the approval of corporate action of merger for 3 state-owned Sharia banks, namely Bank Syariah Mandiri (BSM), Bank Negara Indonesia Syariah (BNIS) and Bank Rakyat Indonesia Syariah (BRIS) by the Financial Services Authority (OJK). The effective date of the merger has become effective starting on February 1, 2021 and is currently becomes Bank Syariah Indonesia (BSI). The merger is an effort for sharia bank to make greater extent in terms of capital, asset, market and image. On the other hand, there are some considerations that must be conducted seriously so that the post-merger phase does not harm all the stakeholders such as parties who have been and will be involved post-merger, status of the employment agreement, cooperation agreement with other parties, and integration of customer data. To analyze this problem, the method used is juridical-normative with conceptual and statute approach. Therefore, the employment agreement must be reviewed between the employer and the employee so that the relationship of labor law is conducted clearly, as well as the review for ongoing cooperation with other parties. In case of data consumer, there must be a guarantee in the process of integrating customer data from 3 banks into 1 bank in the form of big data so that the path to good corporate governance (GCG) for Bank Syariah Indonesia can be achieved measurably. Keywords: Merger, Sharia Bank, and Good Corporate Governance (GCG) AbstrakKomitmen negara memperluas pangsa pasar bank Syariah di Indonesia semakin menjadi kenyataan dengan disetujuinya aksi korporasi berupa merger 3 bank BUMN syariah yaitu Bank Syariah Mandiri, BNI Syariah dan BRI Syariah oleh Otoritas Jasa Keuangan (OJK). Merger telah berlaku efektif mulai tanggal 01 Februari 2021 dan saat ini menjadi Bank Syariah Indonesia (BSI). Merger merupakan ikhtiar untuk membawa bank syariah semakin besar baik dari segi modal, aset, pasar dan image. Namun di sisi lain, terdapat rambu-rambu hukum yang wajib diperhatikan secara serius agar tahap pasca merger tidak merugikan stakeholders yaitu seperti pihak-pihak yang sudah dan akan terlibat dalam operasionalisasi bank, status perjanjian kerja, perjanjian kerjasama dengan pihak lain, dan integrasi data nasabah. Untuk menganalisis masalah ini, metode yang digunakan adalah yuridis-normatif dengan pendekatan konsep (conceptual approach) dan perundang-undangan (statute approach). Oleh karena itu, perjanjian kerja harus ditinjau kembali antara pemberi kerja dan penerima kerja sehingga terciptanya hubungan hukum ketenagakerjaan yang jelas, begitu juga dengan perlunya review perjanjian dengan pihak lain yang sedang berjalan dan akan berjalan serta jaminan pengelolaan dalam fase pengintegrasian data nasabah dari 3 bank menjadi 1 bank dalam sebuah big data. Dengan cara tersebut, jalan menuju good corporate governance (GCG) bagi Bank Syariah Indonesia dapat tercapai dengan terukur. Katakunci: Merger, Bank Syariah dan Tata Kelola Perusahaan Yang Baik

Coastal and marine tourism offer various topics discussed within social media communication during a pandemic. The present study analysed the discussion topics in the popular Twitter's tourism hashtags during the COVID-19 crisis related to coastal and marine tourism. The objectives were to (i) determine the discussion topics, (ii) identify the discussion topics of greater hierarchy, and (iii) determine the tourist destinations discussed. The data were collected from Twitter between March and April 2020. A total of 269,722 tweets were extracted in different languages and globally through the Twitter API of popular tourism hashtags about the COVID-19 pandemic using big data software. The word associations technique was used to process the Twitter data. The discussion topics were ‘travel’, ‘beach’, ‘cruise’, ‘sea’, ‘ocean’, ‘nature’, ‘sun’, ‘coast’, and others. The discussion topics of greatest hierarchy were ‘travel’, ‘beach’, ‘sea’, and ‘cruise’. These topics refer to the motivational dimensions‘ ‘escape’, and ‘sun and beach’. The geographic locations discussed were Spain, Canary, Hawaii, Australia, Caribbean, Bermuda, Florida, California, and others. The findings will contribute to the relationship of the topics with the tourist motivational dimensions, and the destinations discussed about marine and coastal tourism in the time of crisis in the COVID-2019 Pandemic in Twitter's tourism hashtags, and companies will also be able to improve their communication strategies and develop post-pandemic products.

The technological advance of the new era has led to the interconnection of devices, applications, people and data, giving way to the generation of the Internet of Things (IoT). The multiple data collected is so voluminous and variable that it must be stored in Big Data architectures. This evolution has provided the opportunity to have better access, quality and analysis of information, but at the same time, there is a challenge to prevent and mitigate the security risks associated with the relationship between IoT and Big Data, endangering the information collected and the user’ sensitive data, among others. The purpose of this document is to carry out a literature review to collect the security risks found between the relationship of Big Data and IoT, as well as evaluate the current solutions implemented and conclude if they cover the needs for prevention and mitigation of the risk.

The Mesozoic-Cenozoic coral Order Scleractinia has been suggested to have originated or evolved (1) by direct descent from the Paleozoic Order Rugosa or (2) by the development of a skeleton in members of one of the anemone groups that probably have existed throughout Phanerozoic time. In spite of much work on the subject, advocates of the direct descent hypothesis have failed to find convincing evidence of this relationship. Critical points are:(1) Rugosan septal insertion is serial; Scleractinian insertion is cyclic; no intermediate stages have been demonstrated. Apparent intermediates are Scleractinia having bilateral cyclic insertion or teratological Rugosa.(2) There is convincing evidence that the skeletons of many Rugosa were calcitic and none are known to be or to have been aragonitic. In contrast, the skeletons of all living Scleractinia are aragonitic and there is evidence that fossil Scleractinia were aragonitic also. The mineralogic difference is almost certainly due to intrinsic biologic factors.(3) No early Triassic corals of either group are known. This fact is not compelling (by itself) but is important in connection with points 1 and 2, because, given direct descent, both changes took place during this only stage in the history of the two groups in which there are no known corals.

Echinodermata is a phylum of marine invertebrates which has been extant since Cambrian time (c.a. 500 m.y. before the present). Modern examples of echinoderms include sea urchins, sea stars, and sea lilies (crinoids). The endoskeletons of echinoderms are composed of plates or ossicles (Fig. 1) which are with few exceptions, porous, single crystals of high-magnesian calcite. Despite their single crystal nature, fracture surfaces do not exhibit the near-perfect {10.4} cleavage characteristic of inorganic calcite. This paradoxical mix of biogenic and inorganic features has prompted much recent work on echinoderm skeletal crystallography. Furthermore, fossil echinoderm hard parts comprise a volumetrically significant portion of some marine limestones sequences. The ultrastructural and microchemical characterization of modern skeletal material should lend insight into: 1). The nature of the biogenic processes involved, for example, the relationship of Mg heterogeneity to morphological and structural features in modern echinoderm material, and 2). The nature of the diagenetic changes undergone by their ancient, fossilized counterparts. In this study, high resolution TEM (HRTEM), high voltage TEM (HVTEM), and STEM microanalysis are used to characterize tha ultrastructural and microchemical composition of skeletal elements of the modern crinoid Neocrinus blakei.

Electron microscopy has proved to be an invaluable discipline in studies on the relationship of viruses to the origin of leukemia, sarcoma, and other types of tumors in animals and man. The successful cell-free transmission of leukemia and sarcoma in mice, rats, hamsters, and cats, interpreted as due to a virus or viruses, was proved to be due to a virus on the basis of electron microscope studies. These studies demonstrated that all the types of neoplasia in animals of the species examined are produced by a virus of certain characteristic morphological properties similar, if not identical, in the mode of development in all types of neoplasia in animals, as shown in Fig. 1.

In RBL-2H3 rat leukemic mast cells, crosslinking IgE-receptor complexes with anti-IgE antibody leads to degranulation. Receptor crosslinking also stimulates the redistribution of receptors on the cell surface, a process that can be observed by labeling the anti-IgE with 15 nm protein A-gold particles as described in Stump et al. (1989), followed by back-scattered electron imaging (BEI) in the scanning electron microscope. We report that anti-IgE binding stimulates the redistribution of IgE-receptor complexes at 37“C from a dispersed topography (singlets and doublets; S/D) to distributions dominated sequentially by short chains, small clusters and large aggregates of crosslinked receptors. These patterns can be observed (Figure 1), quantified (Figure 2) and analyzed statistically. Cells incubated with 1 μg/ml anti-IgE, a concentration that stimulates maximum net secretion, redistribute receptors as far as chains and small clusters during a 15 min incubation period. At 3 and 10 μg/ml anti-IgE, net secretion is reduced and the majority of receptors redistribute rapidly into clusters and large aggregates.
