"ABSTRAK<>br>Gangguan fungsi TI pada organisasi dapat mengganggu bisnis organisasi. Oleh karena itu menjaga kualitas layanan yang tinggi dengan memaksimalkan ketersediaan layanan dan meminimalkan jumlah incident layanan TI menjadi hal yang penting. Pada kasus insiden mayor yang terjadi, penyelesaian gangguan TI yang berlangsung lama mengakibatkan terganggunya bisnis organisasi. Kecepatan memulihkan layanan setelah terjadinya gangguan tergantung pada seberapa cepat organisasi mengidentifikasi insiden dan seberapa baik disiapkan. Atas kejadian insiden mayor yang terjadi, Pimpinan tertinggi organisasi XYZ berharap adanya langkah taktis dan sistematis dalam antisipasi dan penanganan gangguan terhadap seluruh layanan TIK. Berdasarkan kondisi tersebut, tujuan penelitian ialah mengetahui faktor utama penyebab utama keterlambatan pemulihan layanan TIK yang terjadi sehingga dapat memberikan rekomendasi terhadap masalah dalam pemulihan layanan. Permasalahan pemulihan layanan dilihat dari empat faktor, yaitu Teknologi, Organisasi, Lingkungan dan Individu. Masing-masing faktor tersebut memiliki subfaktor yang didefinisikan pada penelitian sebelumnya. Untuk mengetahui masalah yang terjadi dilakukan wawancara dengan responden yang terlibat langsung serta dokumen terkait dengan pemulihan layanan. Untuk mengetahui faktor/subfaktor yang paling memengaruhi pemulihan layanan, maka dilakukan pembobotan terhadap faktor/subfaktor menggunakan teknik AHP. Hasil pembobotan faktor tertinggi ialah organisasi, sedangkan hasil pembobotan subfaktor tertinggi ialah persepsi manfaat kelangsungan bisnis. Setelah itu dilakukan penyusunan rekomendasi berdasarkan studi literatur. Hasil dari studi literature dilakukan validasi oleh organisasi melalui FGD dan pakar. Hasil penelitian memberikan rekomendasi perbaikan dari masalah yang ditemukan menggunakan pendekatan best practice ITIL.

ABSTRACT<>br>Impaired IT functions in organizations can disrupt the business organization. Therefore maintaining high service quality by maximizing service availability and minimizing the incident number of IT services becomes important. In the case of major incidents, resolving long standing IT disruptions results in disruption of the business organization. The speed of restoring services after the occurrence of interference depends on how quickly the organization identifies the incident and how well it is prepared. On the occurrence of major incidents, top level management of XYZ organization expects a tactical and systematic step in anticipating and handling disruptions to all ICT services. Based on these conditions, this research aim to study the main cause factors of IT disaster recovery problem that occurs so as to provide recommendations for it. IT disaster recovery problem can be identified by 4 factors, which are technology, organization, environment and individual. Each of these factors has a subfactors defined in the previous study. To find out the problem, interviews with the respondents who involved directly as well as documents related to service recovery. To know the factors subfactors that most affect the recovery of services, then weighted factor subfaktor using AHP techniques. The result of the highest weighted factor is the organization, while the highest weighted subfactor result is the perception of business continuity benefit. After that, do the preparation of recommendations based on literature study. The results of the literature study were validated by the organization through FGDs and experts. The results provide an improvement recommendation of the problems using the best practice approach of ITIL."

"The objective of this book is to provide the reader with a comprehensive survey of the topic compressed sensing in information retrieval and signal detection with privacy preserving functionality without compromising the performance of the embedding in terms of accuracy or computational efficiency. The reader is guided in exploring the topic by first establishing a shared knowledge about compressed sensing and how it is used nowadays. Then, clear models and definitions for its use as a cryptosystem and a privacy-preserving embedding are laid down, before tackling state-of-the-art results for both applications. The reader will conclude the book having learned that the current results in terms of security of compressed techniques allow it to be a very promising solution to many practical problems of interest. The book caters to a broad audience among researchers, scientists, or engineers with very diverse backgrounds, having interests in security, cryptography and privacy in information retrieval systems. Accompanying software is made available on the authors’ website to reproduce the experiments and techniques presented in the book. The only background required to the reader is a good knowledge of linear algebra, probability and information theory."

"Creating new medical ontologies for image annotation focuses on the problem of the medical images automatic annotation process, which is solved in an original manner by the authors. All the steps of this process are described in detail with algorithms, experiments and results. In addition, the authors treat the problem of creating ontologies in an automatic way, starting from Medical Subject Headings (MESH). They have presented some efficient and relevant annotation models and also the basics of the annotation model used by the proposed system, cross media relevance models. Based on a text query the system will retrieve the images that contain objects described by the keywords."
