The book covers the recent developments in the field of materials for advancing recording technology by experts worldwide. Chapters that provide sufficient information on the fundamentals will be also included, so that the book can be followed by graduate students or a beginner in the field of magnetic recording. The book also would have a few chapters related to optical data storage. In addition to helping a graduate student to quickly grasp the subject, the book also will serve as a useful reference material for the advanced researcher. The field of materials science related to data storage applications (especially hard disk drives) is rapidly growing. Several innovations take place every year in order to keep the growth trend in the capacity of the hard disk drives. Moreover, magnetic recording is very complicated that it is quite difficult for new engineers and graduate students in the field of materials science or electrical engineering to grasp the subject with a good understanding. There are no competing books in this area, considering that a book that may look 50% similar to the proposed book was published in 2001. A span of 6 years is too long gap, considering the progress this field makes every year.

Dalam tesis ini dibuat model pelayan direktori yang dapat melayani permintaan akses arsip pada sistem terdistribusi.

Model yang dibuat menggunakan memori utama sebagai media untuk menyimpan arsip yang sedang dioperasikan. Ruang memori yang dipakai, lokasinya tersebar didalam sistem. Untuk memudahkan pengelolaan, maka ruang memori tersebut dibagi kedalam blok-blok.

Pelayan direktori terdiri dari dua tingkat pelayan, yaitu pelayan pusat dan pelayan lokal. Pelayan pusat menangani pengelolaan ruang memori keseluruhan secara global dan melayani akses arsip ke disk oleh pelayan-pelayan lokal. Sedangkan pelayan lokal menangani pengelolaan ruang memori secara rinci pada lokasi dimana pelayan lokal tersebut berada dan melayani permintaan akses arsip oleh pemakai. Antar pelayan lokal dapat terjadi saling komunikasi.

Fasilitas pelayanan arsip yang disediakan hanya terbatas pada operasi arsip yang dasar yaitu: operasi buka arsip, operasi baca arsip, operasi tulis arsip dan operasi tutup arsip.

Pelayanan akses arsip oleh beberapa peminta secara serentak dapat dilayani untuk permintaan baca arsip yang serentak ataupun satu permintaan tulis arsip dan lainnya permintaan baca arsip yang terjadi secara serentak. Sedangkan untuk permintaan tulis arsip yang serentak akan dilayani satu persatu secara berurutan. Cara ini diterapkan untuk menjaga suatu arsip selalu dalam keadaan yang konsisten.

Arsip yang sedang dipakai, seluruh datanya akan berada di memori. Sedangkan perubahan-perubahan data yang terjadi hanya akan ditulis ke disk pada saat arsip tersebut di tutup.

Model yang dibuat telah diimplementasikan menggunakan mesin Hewlett-Packard dengan dua buah stasiun kerja, yang fasilitas memorinya masing-masing 4 mega-byte dan 8 mega-byte. Mesin tersebut dioperasikan dengan menggunakan sistem operasi HP-M. Sedangkan untuk keperluan komunikasi antar proses pada model yang dibuat, digunakan protokol TCP/IP.

ABSTRACT
With the strategic position of the Secretariat of the Presidential Advisory Council in providing technical and administrative support to the Presidential Advisory Council in providing advise and consideration to the President, protection of confidential and limited data and information assets of the Presidential Advisory Council from various security threats and risks, confidentiality, integrity, and the availability of data and information is very important. Data storage with a cloud computing system (cloud storage) has several risks including risks of data security, data integrity, and data availability. Blockchain technology offers a decentralized, fast, secure, transparent and recorded data storage system. This research was conducted to determine the appropriate blockchain technology model for the Presidential Advisory Council Secretariat as a solution to the problems in the data storage system, to enhance the performance of the Presidential Advisory Council Secretariat organization.

The method used in this research is case studies, survey respondents and literature studies. Statistical analysis and risk analysis are used to determine the level of risk in the data storage system at the Secretariat of the Presidential Advisory Council that affects the performance of the organization, to then formulate a preventive and corrective response to the most dominant risk. From the research it is known that the most dominant risk is data theft, data damage due to viruses or system attacks, data cannot be stored due to limited storage space, data loss due to system damage and the system does not provide backup data, each user can enter the system without access rights (username and password), and there is no guarantee from the system if there is a security threat. Based on the results of the risk response formulation, as the final result of the study, a risk-based data storage system model was created with a blockchain technology platform that is appropriate for the Secretariat of the Presidential Advisory Council to improve the Secretariat of the Presidential Advisory Council performance.

This book presents the latest research findings, as well as innovative theoretical and practical research results, methods and development techniques related to P2P, grid, cloud and Internet computing. It also reveals the synergies among such large scale computing paradigms. P2P, Grid, Cloud and Internet computing technologies have rapidly become established as breakthrough paradigms for solving complex problems by enabling aggregation and sharing of an increasing variety of distributed computational resources on a large scale. Grid computing originated as a paradigm for high-performance computing, offering an alternative to expensive supercomputers through different forms of large-scale distributed computing. P2P computing emerged as a new paradigm following on from client-server and web-based computing and has proved useful in the development of social networking, B2B (Business to Business), B2C (Business to Consumer), B2G (Business to Government), and B2E (Business to Employee). Cloud computing has been described as a “computing paradigm where the boundaries of computing are determined by economic rationale rather than technical limits”. Cloud computing has fast become the computing paradigm with applicability and adoption in all domains and providing utility computing at large scale. Lastly, Internet computing is the basis of any large-scale distributed computing paradigm; it has very quickly developed into a vast and flourishing field with enormous impact on today’s information societies and serving as a universal platform comprising a large variety of computing forms such as grid, P2P, cloud and mobile computing.
