Universitas PGRI Sumatera Barat has wi-fi which does not rule out attacks on wi-fi networks carried out by hackers. Network Security is a protector in a network system in the process of preventing unauthorized and irresponsible network users. This research includes descriptive research. Descriptive research method is a research method that aims to explain an event. This research was conducted by testing and analyzing the test results on network security using Wireshark and Ettercap applications (Kali Linux OS). The results of this study in the form of a wi-fi network security system in building A1, building B1, building D1 at University of PGRI West Sumatra is good. During the scan for hosts, the IP of the laptop victim of the packet snffing attack was not found.

This research is aimed at measuring experts' validation on the use of LMS by Senior High School and Vocational High School teachers in West Sumatera in online learning. The researchers used two validators as the experts in e learning who had done many researches in e learning. Indicators of construct validity were adopted from Gendon Barus, with 16 aspects of instrument quality. The aspects were used to asses each item in the instrument. Data were collected through questionnaire. Then they were analyzed quantitatively by using Aiken's V. Result showed that the construct validity of the instrument is .712 with the V is .712 > .600. Based on the result, the researchers conclude that instrument is valid so that it can be used in investigating the use of LMS by the teachers.

The purpose of this study is to develop e-module-based learning media using the Sigit editor software. Development of learning media based on e-modules in AIJ subjects that are valid and practical. Based on the problems previously described, this type of research uses the R&D (Research and Development) development research model which aims to produce application products and test the effectiveness of these products. The results of research on the development of E-modules in AIJ subjects that have been tested for the validity of developing E-modules in AIJ Class XI TKJ subjects at SMK Negeri 1 Rao Selatan, state that the e-module is very valid, namely material validity is 0.9 and media validity is 0.822 and the practicality test for the development of E-modules in the AIJ Class XI TKJ subject at SMK Negeri 1 Rao Selatan, declared practical by the teacher and with 100% practicality and 86.6% students.

Majunya perkembangan teknologi telah mencapai tingkat menjadi kebutuhan, sebagai akibatnya seluruh lapisan rakyat termasuk mahasiswa, dosen perguruan tinggi tergerak buat maju dan menggunakannya. Perkembangan teknologi keterangan juga memegang proses dalam ruang lingkup universitas agar dapat meningkatkan efektifitas dan efisiensi kerja. Hal ini mendorong penulis untuk merancang sistem informasi pengelolaan sertifikat dan hitung kredit poin pada universitas PGRI Sumatera Barat. Sistem informasi atau website online yang nantinya akan dapat membantu dalam menyimpan dan menghitung kredit poin. Metode pengumpulan data yang digunakan dalam penelitian ini yaitu observasi dan wawancara. Model pengembangan sistem ini menggunakan SDLC (system Development Life Cycle). Dalam merancang aplikasi ini digunakan perancang struktural yaitu pembuatan context diagram UML (Unified Modeling Language), dalam pembuatan perangkat lunak ini menggunakan PHP sebagai script yang digunakan untuk membuat halaman website dan MYSQL sebagai database yaitu tempat penyimpanan data. Hadirnya sistem ini ini dapat membantu proses penyimpanan dan perhitungan kredit poin yang dilakukan oleh mahasiswa dan dosen. Hasil dari sistem ini adalah dapat membantu program studi sistem informasi dalam pelayanan penyimpanan dan perhitungan kredit poin.

Tujuan penelitian ini untuk merancang sistem informasi program kerja organisasi kemahasiswaan dalam melakukan pengajuan program kerja untuk satu periode kedepan, dan proposal serta laporan pertanggungjawaban kegiatan. Dilakukannya penelitian ini untuk mengefisienkan waktu karena organisasi kemahasiswaan harus mengajukan program kerja, proposal ataupun laporan pertanggungjawaban secara langsung, dimana sewaktu-waktu pihak yang ingin ditemui tidak berada ditempat. Pemanfaatan sistem informasi berbasis web dapat meminimalisir penggunaan waktu, karena proses sudah dilakukan secara terkomputerisasi. Analisis dalam penelitian ini menggunakan konsep Software Development Life Cyrcle (SDLC). Perancangan sistem ini dibuat dengan bahasa permodelan Unified Modeling Langunge (UML). Sistem informasi program kerja organisasi kemahasiswaan dibuat menggunakan bahasa pemograman PHP, Laravel, HTML, CSS dengan menggunakan database. Berdasarkan hasil penelitian sistem informasi program kerja organisasi kemahasiwaan yang telah peneliti lakukan bahwa terbangunnya sistem informasi yang dirancang meggunakan metode Software Development Life Cyrcle (SDLC) dengan model waterfall yang terdiri dari lima tahapan yaitu, analisa kebutuhan, desain program, penulisan kode program, pengujian program dan penerapan program.

What can do one of the ways to increase student interest in reading by increasing the collection of books in the Kerinci IAIN library. But so far, determining the collection of books to be added is still done manually, so it takes a long time besides that the process of adding books which refers to the statistics of borrowing the most books, makes the collection of books less diverse. For this reason, a book collection clustering method is needed using the k-Means method to obtain optimal results. Book collections are grouped into 3 clusters that are, considerations that need to be added, priorities to be added, and not need to be added can be a reference for librarians in maximizing the process of adding book collections.

Online learning has become an option to be implemented in various schools because the development of IT technology and the COVID-19 pandemic have made online learning more popular to implement. Mobile LMS is the most dominant used in online learning. This study aims to produce a Mobile LMS framework developed from previous research based on the advantages and disadvantages. The review method used narrative review by identifying and summarizing previously published articles, avoid duplication of research, and look for new fields of study that have not been studied. The literatures are focused on three things such as (1) Mobile LMS theory, concept and approach, (2) Mobile LMS design and framework, and (3) Mobile LMS implementation. From articles researching about Mobile LMS published in reputable journals, there are 17 purposive selected papers. Based on the literature review, the Mobile LMS framework has not been integrated into devices and operating systems. Therefore, the author developed a Mobile LMS framework design based on Multiplatform, which is integrated by device and operating system based on references that have been used by previous researchers. This new Mobile LMS framework can be a reference for teachers and future researchers.
