Implementasi Jaringan VPN untuk Mengurangi Biaya Komunikasi Menggunakan Metode EoIP Over PPTP: Studi Kasus House Printing

Perusahaan di bidang percetakan masih sangat dibutuhkan, meski dunia digital kini semakin berkembang pesat. Banyak korporasi masih membutuhkan media cetak sebagai penunjang untuk memenuhi kebutuhan perusahaan. House Printing adalah salah satu perusahaan di bidang percetakan yang masih berkembang, dengan perkembangan teknologi saat ini kebutuhan akses data tidak cukup dibebankan dengan akses lokal saja, sehingga dibutuhkannya struktur jaringan yang mampu mengakses data lebih cepat meski dengan jarak jauh sekalipun. Selain itu, koneksi jaringan yang dibutuhkanpun tidak ingin terpaku oleh salah satu provider saja. Sebagai perusahaan industri kreatif yang sedang berkembang dengan mengikuti perkembangan teknologi yang ada, House Printing memiliki tanggung jawab penuh untuk memberi layanan terbaiknya kepada para pelanggannya. Tidak hanya sekedar meliputi produk atau jasa yang ditawarkan, akan tetapi berkaitan dengan akses data dari kantor cabang ke kantor pusat atau sebaliknya. Terlebih dengan kondisi pandemic yang tak kunjung usai, yang mengharuskan karyawan bekerja dari rumah. Dengan file grafis yang memiliki ukuran kapasitas yang cukup besar, sangat menghambat kinerja perusahaan jika hanya transfer data melalui email saja. Selain itu menjadikan pelayanan perusahaan tidak efektif dan kurang memuaskan bagi pelanggan apabila terdapat gangguan jaringan dll, karena tidak dapat akses ke kantor pusat. Dengan menyesuaikan kondisi perusahaan dan kebutuhan dukungan jaringan pada perusahaan, salah satu opsi penyelesaian masalah untuk transfer data agar lebih mudah adalah dengan menggunakan metode VPN atau dengan menggunakan metode Cloud Storage. VPN atau yang disebut juga Virtual Private Network merupakan salah satu alternatif pengaman data yang bersifat privat yang memungkinkan penggunaannya untuk perusahaan berkembang dengan efisiensi biaya untuk perusahaan.

Blockchain technology design in accounting: Game changer to tackle fraud or technological fairy tale?

PurposeThis paper aims to design, build and evaluate a blockchain platform in the accounting domain, taking an ecosystem perspective. To achieve this aim, the research provides evidence for developing a decentralised architecture rooted on blockchain technology, designing a proof of concept and modelling an accounting blockchain-based system.Design/methodology/approachMoving from the analysis of previous literature and leveraging on the design science approach, this paper provides a framework grounded on the main pillars of blockchain and accounting functions, identifying technical and non-technical issues that must be addressed embrace blockchain technology's full potential.FindingsWe propose and discuss a conceptual framework for a blockchain-based accounting context, moving from the identification of a typical accounting scenario. The framework is organised around three scalable levels: the first level is a technological infrastructure based on a distributed database with peer-to-peer storage; second, in the intermediate level, increasing control levels are assured through permissions and validation and third, in the higher level, the system provides the integration of business and security applications. The deployment of this system relies on a private network of nodes that validates transactions.Practical implicationsThe proposed conceptual framework about blockchain development in accounting allows closing the knowledge gap between blockchain developers and accounting experts by suggesting technological and strategic issues for practitioners.Originality/valueWe provide practical guidelines to design and adopt blockchain in the accounting domain.

The Use of 5G Technologies in the Digital Transformation of the Oil/Gas Industry

Many oil & gas companies embarked on their Digital Transformation (DX) journeys with rapid adoption of emerging digital technologies. Successful digital transformation initiatives are necessary for Oil/Gas Companies to improve efficiencies, streamline their operations and meet pressing challenges for cost reduction, increased efficiency, and improved safety. Oil & Gas fields and processing facilities require robust and reliable telecommunication infrastructure to support the application of much needed digital technologies. The availability of high-speed connectivity has been a challenge for many Oil/Gas companies operating in remote or hazardous locations. The latest Fifth Generation cellular technology (5 G) addresses such essential Oil/Gas requirements as increased speeds/bandwidths, very low network latencies, ultra-reliable communications, and the capacity to handle large number of users. 5G is designed around following technologies: Small (micro) cells requiring less power,Higher frequencies offering bigger data handling capacities,Cloud and Edge Computing for low network latencies and added security. These 5G design features will enable numerous Oil/Gas applications such as Industrial Robots/Drones, Virtual/Augmented Reality, Video Surveillance with Artificial Intelligence (AI) features (Face Recognition, Object Recognition & intelligent Image processing), Remote Asset Management, Industrial IoT communication between Sensors, Gateways and Device Controllers, Pipeline Leak Detection Systems, Telemetry and SCADA. 5G is therefore poised to be a key enabler in Digital Transformation. The UAE has an advanced telecom infrastructure that offers customers high speed fibre optic connectivity. UAE telecom operators have also been quick to deploy 5G in main cities. Etisalat for example is running a 5G pilot on Das Island with ADNOC Offshore and a major Network Supplier to test potential use cases of the technology in the O&G industry. The push for 5G in O&G will benefit from cooperation between the O&G industry, the telecom operators and technology providers. The role of Governments and the Telecom Regulators can further accelerate adoption through allocation of frequency spectrum to enable 5G Private Network model of deployment. The private network model is crucial for the Oil & Gas industry in view of the special requirements, nature and remoteness of oil and gas installations.

The constraints, aesthetic implications, and creative strategies of composing for networked music performance

<p>Performing music together over a public network while being located at a distance from each other necessarily means performing under a particular set of technical and performative constraints. These constraints are antithetical to—and make cumbersome—the performance of tightly synchronised music, which traditionally depends on the conditions of transmission stability, ultra-low latency, and shared presence. These conditions are experienced optimally only when musicians perform at the same time and in the same place. Except for specialized private network services, public networks are inherently latent and unstable, which disrupts musicians’ ability to achieve precise vertical synchronisation and create an environment where approaches to music performance and composition must be reconsidered. It is widely considered that these conditions mean that networked music performance is a future genre for when network latencies and throughput improve, or one that is currently reserved for high-end heavily optimised networks afforded by institutions and not individuals, or one that is primarily reserved for improvisatory or aleatoric composition and performance techniques. I disagree that networked music is dependent on access to advanced Internet technologies and suggest that music compositions for networked music performance can be highly successful over regular broadband conditions when the composer considers the limitations as opportunities for new creative strategies and aesthetic approaches. In this exegesis, I outline the constraints that prove that while networked music performance is latent, asynchronous, multi-located, multi-authorial, and hopelessly, intrinsically, and passionately digitally mediated, these constraints provide rich creative opportunities for the composition and performance of synchronised and resonant music. I introduce four aesthetic approaches, which I determine as being critical towards the development of networked music: 1) postvertical harmony, where the asynchronous arrival of signals ruptures the harmonic experience; 2) new timbral fusions created through multi-located resonant sources; 3) a contribution to performative relationships through the generation and transmission of vital information in the musical score and through the development of new technologies for facilitating performer synchronisation; and 4) the post-digital experience, where all digital means of manipulation are permitted and embraced, leading to new ways of listening to and forming reproduced realities. Each of these four aesthetic approaches are considered individually in relation to the core constraints, through discussion of the present-day technical conditions, and how each of these approaches are applied to my musical portfolio through practical illustration.</p>

Educational Blockchain: A Secure Degree Attestation and Verification Traceability Architecture for Higher Education Commission

Degree attestation verification and traceability are complex one-to-one processes between the Higher Education Commission (HEC) and universities. The procedure shifted to the digitalized manner, but still, on a certain note, manual authentication is required. In the initial process, the university verified the degree and stamp seal first. Then, a physical channel of degree submission to the receiving ends is activated. After that, the degree is attested while properly examining and analyzing the tamper records related to degree credentials through e-communication with the university for verification and validation. This issue poses a serious challenge to educational information integrity and privacy. Potentially, blockchain technology could become a standardized platform to perform tasks including issuing, verifying, auditing, and tracing immutable records, which would enable the HEC, universities, and Federal Education Ministry (FEM) to quickly and easily get attested and investigate the forge proof versions of certificates. Besides, decentralized distributed data blocks in chronological order provide high security between distributed ledgers, consensus engine, digital signature, smart contracts, permissioned application, and private network node transactions that guarantee degree record validation and traceability. This paper presents an architecture (HEDU-Ledger) and detail design of blockchain-enabled hyperledger fabric applications implementation for degree attestation verification and traceable direct channel design between HEC and universities. The hyperledger fabric endorses attestation records first, and then validates (committer) the degree and maintains the secure chain of tracing between stakeholder peer nodes. Furthermore, this HEDU-Ledger architecture avoids language and administrative barriers. It also provides robustness in terms of security and privacy of records and maintains integrity with secure preservation as compared to that of the other state-of-the-art methods.
