Abstract

An email service provider or email server is a very important application for a company. With the development of information technology and internet crime, there is a possibility of attacks on the email server resulting in dense email server traffic, thus slowing the performance of the email server and disrupting the service to email server users. One of the attacks that occurred was a DDOS (Distributed Denial of Service) attack where the attack paralyzed server performance by sending many packets from various sources of IP addresses to one target. One of the DDoS attacks on the email server is to disable the SMTP, IMAP, POP3 protocols. Prevention of this attack can be done with Fail2ban which can detect unusual activity and perform an automatic block. In this study using the NDLC method, starting from analysis, design, simulation, and implementation. The results obtained by implementing fail2ban to prevent DDoS attacks on email servers can reduce incoming spam by up to 21%.

Abstract

Penelitian ini dilakukan untuk menganalisa dan menggagas model pembelajaran yang berpotensi meningkatkan efektivitas pembelajaran daring dengan cara meningkatkan student engagement dan motivasi belajar melalui penerapan Virtual Reality dan Gamification in Learning. Analisa dilakukan dengan metode meta-analisis jurnal dimana tim penulis melakukan penelusuran terhadap berbagai sumber artikel dan jurnal untuk menggagas suatu model pembelajaran menarik untuk diterapkan dalam pembelajaran jarak jauh. Melalui penelitian, ditemukan bahwa model pembelajaran daring yang saat ini digunakan belum efektif serta berisiko menurunkan student engagement dan motivasi belajar. Dengan keunikannya dalam menjaring student engagement, teknologi Virtual Reality dan gamification in learning dapat dipertimbangkan sebagai pelengkap, media, dan metode untuk pembelajaran daring

Abstract

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

The application of online application-based transportation services that are growing rapidly. One of the factors of this online application-based transportation service innovation is the growing number of internet services offered by internet service providers and more and more internet users, so that the internet becomes a necessity and lifestyle for the community. This research is a development of previous research in examining the factors that influence public acceptance of online transportation applications using the UTAUT2 research model; the current study uses the Technology Acceptance Model research model. This questionnaire was distributed to 400 respondents to the residents of the Riau Islands using Amos and SPSS. The results of the analysis of transportation application online acceptance in Riau Kepulauan using Technology Acceptance Model were seen from the construct of behavioral intention use to attitude toward using is 100%, actual system use to behavioral intention to use is 94.7%, perceived usefulness to perceived ease of use is 80.3%, attitude toward using to perceived usefulness is 47.6% whereas behavioral intention use to perceived usefulness is not effected as positive.

Abstract

SMK Negeri 2 Batam adalah sekolah negeri yang berdiri sejak tahun 2006 dengan akreditasi A yang terletak di kota Batam, Jalan Pemuda 5, Legenda Malaka. Salah satu ciri kemajuan suatu bangsa dapat dinilai dari kualitas pendidikannya. Karena pendidikan memegang peranan yang sangat penting dalam memberikan kesan kepada generasi penerus bangsa. Saat ini bahasa Inggris merupakan salah satu bahasa asing yang wajib dipelajari setiap orang, karena bahasa Inggris merupakan bahasa internasional yang digunakan sebagai bahasa komunikasi antar negara.
