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%.

Abstrak. Banyak teori belajar serta pendekatan pengajaran menyarankan pretest sebagai alat diagnostik guru. Pretest Esai bahasa Inggris digunakan untuk mengidentifikasi informasi yang cukup tentang pemahaman objektif setiap siswa tentang pelajaran pertama kalinya. Tujuan dari penelitian ini adalah untuk mengidentifikasi setiap keterampilan kemahiran siswa dalam menulis esai naratif bahasa Inggris di prodiPendidikanBahasaInggris, Universitas HKBP Nommensen Pematangsiantar. Populasi subjek penelitian adalah 34 siswa dalam kelompok B dan penulis memilih 10 tugas siswa secara acak sebagai sampel. Ini adalah deskriptif kualitatif dengan pendekatan studi kasus. Menurut Ary (2010: 29) penelitian kualitatif berusaha memahami suatu fenomena dengan memfokuskan pada gambaran total daripada memecahnya menjadi variabel. Analisis data, temuan penelitian, dan diskusi menunjukkan bahwa siswa menulis paragraf mereka tidak disusun secara struktural. Penelitian ini menemukan bahwa 12 paragraf (30%) memiliki struktur yang kompleks. 28 paragraf lainnya (70%) tidak memiliki struktur lengkap. Hasilnya menunjukkan bahwa lebih banyak siswa yang tidak mengerti menulis paragraf mereka secara struktural.Kata kunci: Narasi, Esai Bahasa Inggris, Struktur Paragraf, Pretest.Abstract: Many study theories as well as teaching approaches suggest pretest as a teacher diagnostic tool. Pretest of narrative English essay are used to identify a fairly information about the objective understanding of each students about the lesson for the first time. The purpose of this research is to identify every student proficiency skill on writing narrative English essay in English Language Education Department, University of HKBP NommensenPematangsiantar. The population of the subject research was 34 students in group B and the writer chose 10 students assignments randomly as samples. This is descriptive qualitative and case study approach. According to Ary (2010:29) qualitative researchers seek to understand a phenomenon by focusing on the total picture rather than breaking it down into variables.

For a person with visual disabilities, in modern times it is not an obstacle for them to study in order to get good and highest possible insights, therefore an Artificial Intelligence is created or it can be called (Artificial Intelligence). Artificial Intelligence can be said as robots that mimic human behavior, the purpose of Artificial Intelligence is to facilitate an activity or work for humans. One example is (Speech Recognition). Speech Recognition is a process that identifies the sound that comes from the pronunciation of a spoken word, Speech Recognition is a system that can recognize voices from humans and then translate it into data that can be captured by a computer system. Blindness is a general term used for the condition of a human who experiences disturbances or obstacles in the sense of sight.

The COVID-19 pandemic can threaten human lives and can spread massively if there are no comprehensive preventive measures in all countries including Indonesia. Various efforts are known to be made to prevent the spread of COVID, including the use of hand sanitizers, which are antiseptic fluids capable of killing viruses, bacteria, and fungi found in the air, tools, and the human body, including hands. . The method of activities carried out in this community service is counseling using the lecture method using power point slide media which contains an explanation of the importance of a hand sanitizer and demonstrating directly with a hand swab from a community before and after using a handsanitizer and then scratching it on PDA media (Potato Dextrose Agar). The conclusion of this community service is that the community understands the importance of using a handsanitizer before carrying out activities because they see directly the growing bacteria.

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
