Teknologi Informasi memiliki peran penting bagi perusahaan dalam mengolah dan menyediakan informasi yang dibutuhkan oleh para stakeholder. Namun, tidak semua perusahaan mampu mengimplementasikan dan mengembangkan teknologi informasi yang bersesuaian dengan kebutuhan perusahaan, termasuk PT XYZ. PT XYZ merupakan perusahaan jasa yang bergerak dibidang sertifikasi Verifikasi Legalitas Kayu (VLK). Dalam menjalankan perusahaannya, PT XYZ didukung oleh fungsi Manajemen Umum dan Keuangan. Namun seiring berjalannya waktu, fungsi Manajemen Umum dan Keuangan tidak dapat menyesuaikan dengan cepat perkembangan teknologi yang ada. Hal ini ditandai dengan terbatasnya sistem yang digunakan oleh perusahaan seperti Microsoft Excel. Penggunaan TI yang belum optimal berdampak pada internal dan eksternal perusahaan, yang menyebabkan terjadinya penurunan tingkat loyalitas pelanggan sebesar 46,43% selama setahun terakhir. Untuk itu diperlukan solusi Enterprise Architecture (EA) guna menyelaraskan kebutuhan bisnis dan teknologi, juga mengoptimalisasi pengembangan teknologi informasi. Enterprise architecture dirancang menggunakan metode TOGAF ADM. Perancangan EA dimulai dari Preliminary Phase sampai Information System Architecture (Application Architecture). Penelitian ini akan menghasilkan artefak berupa matrices, catalog, dan diagram. Adapun hasil akhir penelitian ini adalah rancangan Blueprint Enterprise Architecture sebagai gambaran umum usulan proyek untuk mendukung strategi bisnis dan pengembangan teknologi pada fungsi Manajemen Umum dan Keuangan di PT XYZ.

Proses Akreditasi Perguruan Tinggi merupakan proses yang membutuhkan banyak sumber daya. Bagi perguruan tinggi dengan sumber daya terbatas, penggunaan teknologi informasi dan komunikasi menjadi salah satu solusi untuk persiapan akreditasi. Permasalahan muncul ketika stakeholder dan anggota organisasi perguruan tinggi tidak memiliki informasi tentang potensi teknologi informasi yang tersedia dan dibutuhkan. Enterprise architecture merupakan blueprint untuk memahami struktur teknologi informasi dan komunikasi di organisasi. Pemanfaatan enterprise architecture memudahkan pengelola perguruan tinggi untuk memaksimalkan dan mengembangkan teknologi informasi dan komunikasi yang dimiliki. TOGAF-ADM sebagai framework enterprise architecture menawarkan fleksibilitas dan sifat generik penggunaan artefak enterprise architecture. Sifat fleksibel dan generik ini menjadi masalah dikarenakan cakupannya yang sangat luas menyebabkan banyaknya opsi artefak yang disediakan. Penelitian-penelitian yang disebutkan sebelumnya, belum mencantumkan alasan pemilihan artefak yang digunakan.. Penelitian ini bertujuan untuk menyusun arsitektur bisnis dan data dengan framework TOGAF-ADM berorientasi artefak. Penelitian dilakukan dalam 4 tahap. Tahap pertama, implementasi preliminary phase, diikuti tahap kedua fase architecture vision. Tahap ketiga fase Business Architecture dan tahap keempat fase information system architecture. Hasil yang diperoleh tersusun 8 artefak. Artefak katalog prinsip tersusun dari 2 prinsip bisnis, 1 prinsip data, 2 prinsip aplikasi dan 1 prinsip teknologi. Artefak functional decomposition diagram baseline dan target menunjukkan diperlukannya empat proses bisnis tambahan meliputi manajemen data tracer study, evaluasi penelitian dosen, evaluasi pengabdian dosen, monitoring penelitian dosen, monitoring pengabdian dosen dan manajemen data dosen dan mahasiswa. Pada artefak organizational decomposition diagram dan role catalogue terdapat tugas dan peran setiap stakeholder terkait proses akreditasi. Artefak data entity/business function matrix dan data to role access matrix berisikan entitas data yang digunakan dalam proses akreditasi serta tugas dari setiap stakeholder terkait dengan pengelolaan data.

IAPT 3.0 merupakan Instrumen Akreditasi Perguruan Tinggi yang telah ditetapkan pada tahun 2019 oleh Badan Akreditasi Nasional Perguruan Tinggi. IAPT 3.0 merupakan instrumen penilaian terbaru yang telah disesuaikan dengan peraturan perundangan terkini dan sebagai upaya perbaikan berkelanjutan. Salah satu perubahan pada IAPT 3.0 terletak pada penilaian Kerjasama di Pendidikan Tinggi. Institut Teknologi Telkom Purwokerto (ITTP) sebagai salah satu perguruan Tinggi swasta di Jawa Tengah merasa perlu beradaptasi dengan instrumen akreditasi yang baru ini untuk meningkatkan nilai akrerditasi Perguruan Tinggi. Permasalahan yang dihadapi oleh ITTP untuk proses bisnis Kerjasama adalah seluruh aktivitas masih dilakukan secara manual dan belum terintegrasi. Permasalahan tersebut menjadikan ITTP perlu berinovasi dengan teknologi untuk menyelaraskan antara strategi bisnis dan teknologi informasi khususnya pada proses bisnis Kerjasama. Penyelarasan dilakukan dengan membuat enterprise architecture (EA) yang sesuai dengan proses bisnis Kerjasama pada ITTP. Perancangan EA menggunakan TOGAF ADM yang meliputi fase preliminary phase, architecture vision, business architecture, information system architecture, technology architecture, opportunities and solutions dan migration planning. Hasil yang diperoleh pada penelitian ini adalah rancangan EA yang telah disesuaikan pada  proses bisnis Kerjasama di ITTP dan architecture roadmap yang disusun menggunakan metode Promethee. Berdasarkan metode Promethee, urutan pengembangan aplikasi ePartnership sesuai dengan fungsionalitas sistemnya adalah diawali dengan pembuatan fungsionalitas pengajuan Kerjasama, alert system, dan terakhir adalah evaluasi kegiatan Kerjasama.

PT.XYZ is a gas oil manufacturing company, which produces offshore oil and gas drilling equipment. In supporting its business processes, this company uses a separate module application which causes data flow to be interrupted and results in the company experiencing delays in managing data and getting information on time. Based on the analysis of the problem, the researcher will design an integrated enterprise information system architecture for sales, finance, raw material procurement, production, project plan, and inventory. The method used is the TOGAF ADM 9.2 framework which consists of four phases, namely the vision architecture, business architecture, information system architecture, and technology architecture phases. This enterprise architecture design produces a blueprint as a guideline or framework in the development of information systems at PT. XYZ. The overall result of this research is to produce an enterprise architecture information system design

Universities in Indonesia already have academic information systems. This university in developing its academic information system is carried out individually according to conditions and needs. Currently there are no guidelines in providing direction for the planning, development, implementation and service of academic information systems based on information and communication technology in universities. In addition to this, it is based on the planning and development of an academic information system which is what will be planned and developed and how its development guidelines are not yet available. The purpose of this study is to provide guidance in building academic information systems at private universities that can be applied in South Sumatra Province. This goal needs to be done because in general the academic information system business processes and services as well as the need for information in each university have in common namely the acceptance of new students, academic management and academic release. The result of the research is an academic information system architecture as a guideline in planning the development of an academic information system according to the conditions of private universities in South Sumatra Province. This study uses the EAP method with the steps of activities including planning initiation, business modeling and survey of current institutions, systems and technologies, data architecture and application architecture. The results of this study are a guide in building a system in the form of an academic information system architecture that can be applied to private universities in Indonesia especially South Sumatra Province.This study uses the EAP / Enterprise Architecture Planning method with activity steps including planning initiation, business modeling and institutional surveys, current systems and technology, data architecture and application architecture.

A new class of information system architecture, decision-oriented service systems, is spreading more and more. Decision-oriented service systems provide services that support decisions in business processes and products based on the capabilities of cloud-computing environments. To pave the way for the creation of design methods of business processes and products based on decision-oriented service systems, this article introduces a capability-oriented approach. Starting from technological capabilities, more abstract operational and dynamic capabilities are created. The framework created is based on an integrated conceptualization of decision-oriented service systems that allows capturing synergetic effects. By creating the framework, the gap between the technological capabilities of technologies and the strategic goals of enterprises shall be narrowed.

Global supply chain crisis management has become increasingly crucial for tackling unusual incidents (e.g., natural disaster, terrorism, pandemic). While crisis management has focused on a few organizations involved in supply chain operations (manufacturers, governments, carriers, and the consuming public), it has primarily received a functional focus. Due to their decentralized network structure, supply chains are prone to suffer from disruptive events solved by supply chain crisis management. This chapter presents the blockchain technologies' possibilities and limits used in an integrated IoT-based information system architecture. The chapter describes how the scalability limits of blockchain technology affect the proposed architecture performance that uses it. Also, the chapter presents a review of the academic literature, pointing out how some solutions use a centralization process to improve response time and security of the blockchain-based architecture. Finally, the chapter provides security threat models, which consider by blockchain protocols in IoT networks.
