<![CDATA[PT. Minori is an apprentice delivery company to Japan located in Cikarang Bekasi. The apprentices to be sent to Japan must first follow the selection and education process. Even after arriving in Japan, the apprentices must take part in lessons too so they will not forget the educational material and move up to a higher level. The learning method during education is by accessing the Education server in LAN (Local Area Network) and accessing the cloud server during internship. The difference in location and network causes problems, the data that is on the local network server with the public network server, how to synchronize the data without changing the existing network infrastructure. Database synchronization in PT Minori is done by restful API from both servers to synchronize data.]]>

<![CDATA[The availability of supporting devices in the academic services of a university is inseparable from the location and placement and also the need for these devices. The need for operational equipment is a necessity in the running of business process activities at a university, therefore the types of operational devices and facilities provided are a benchmark for a university in providing the best service to the academic community in it. In a tertiary institution, the need for operational equipment plays an important role in carrying out the teaching and learning process, on the other hand, behind-the-scenes operations also play an active role in ensuring the learning and teaching process runs. The need for operational equipment for infrastructure and facilities will increase where if a university has a building or branch with a different location, with this condition new findings will appear, the types of operational goods proposed are not balanced between branches or the number of goods that will be served by each branch is not monitored. Therefore, an infrastructure information system was built to facilitate and monitor each branch of the university in managing the equipment and operational facilities and infrastructure at the branch of the college building.]]>

<![CDATA[In the world of education, exam is the final stage to evaluate the student abil-ity. The length of the correction process and the expensive cost of printing for manually exams are obstacles that often occurs when administering the ex-ams. Computer-based exams is an effort that is present to solve the problems, by using a computer, then the cost of printing documents and others can be minimized, besides that there is no need for manually correction time, be-cause when students finished the exam, the student's grades can be immedi-ately known. So many advantages are offered by computer-based exams but of course there are still problems that arise. The most common thing is the slow server in processing requests from clients when accessed together, in-creasing the number of servers using Network File Server is one of the efforts to correct the shortcomings of computer-based exams. Using Network File Server is expected to be able to overcome these problems.]]>

<![CDATA[Komunikasi jaringan internet butuh keamanan, kemudahan, dan kecepatan transfer data yang baik. Hal ini harus diperhatikan oleh setiap pengguna dalam melakukan kegiatan di dunia maya atau internet, sehingga kerahasiaan informasi bisa terjaga dengan baik dan kemudahan, kecepatan pertukaran data bisa di implementasikan sehingga dapat menjadi suatu nilai lebih. VPN dapat terjadi antara dua PC atau bisa juga antara dua atau lebih jaringan yang berbeda. VPN dapat dibentuk dengan menggunakan teknologi tunneling dan encryption. Server OpenVPN menghasilkan profil jaringan terenkripsi, kemudian semua pengguna dapat membentuk jaringan VPN dan mereka dapat menggunakan layanan organisasi seolah-olah mereka secara geografis berada di tempat yang sama, konfigurasi ini juga memungkinkan penggunaan layanan atau aplikasi eksternal apa pun tanpa memengaruhi keamanan organisasi, VPN dapat berjalan pada IPv6 dan IPv4, dengan kelebihan yang banyak OpenVPN melintasi NAT (Network Address Translation). Jaringan VPN ini dibuat untuk memudahkan pekerja yang sedang melaksanakan aktivitas WFH (Work From Home) VPN sebuah koneksi virtual yang bersifat private dan tidak semua orang bisa mengaksesnya. Implementasi VPN dapat mempermudah komunikasi data jarak jauh tanpa khawatir ada tabrakan data, karena dengan menggunakan jaringan virtual ini dapat terhubung secara bersamaan. Dengan VPN, pengguna mempunyai keamanan data yang lebih dibandingkan dengan menggunakan jaringan lokal biasa. Ketika pengguna terhubung ke jaringan VPN maka akan mempunyai IP yang berbeda dengan IP Physical dibuktikan dengan tool tracert terlihat IP dan hoop. Raspberry Pi berfungsi untuk membuat sertifikat VPN client, karena fungsi tersebut tidak digabungkan ke dalam VPS Server karena masalah keamanan jaringan.]]>

<![CDATA[Human resources are the most valuable asset in a company. Employee performance is one of the company's benchmarks in assessing the productivity of these assets. Methods in measuring employee performance can be done in various forms, one of which is using the fuzzy logic method. Fuzzy Mamdani is a fuzzy inference method that provides rules that must be passed before carrying out the process of determining the final value. There are three main criteria that will be analyzed in this study, namely attendance, quality of work and communication. Each of these criteria has a value obtained from the average value of several elements. The final result after going through the employee data analysis process is the average weighted value. Conclusions that can be drawn as the basis for employee performance and the results can be seen from the order of values, starting from the highest to the lowest. MATLAB or what we call it (Matrix Laboratory) is a program for analyzing and computing numerical data, and MATLAB is also an advanced mathematical programming language, which was formed on the premise of using the properties and forms of matrices. Graphical User Interface (GUI) is a visual media that makes users give certain commands on the computer without typing the command, but using the available images.]]>

<![CDATA[Jaringan komputer tentunya sangat dibutuhkan oleh sebuah institusi maupun perusahaan untuk dapat melakukan pertukaran data maupun mengerjakan pekerjaan dengan koneksi internet, maka bandwidth perlu diatur untuk kerja perusahaan, karena dengan adanya sebuah internet maka penyebaran data menjadi efisien dan informasi menjadi semakin luas. Akan tetapi, realitanya jaringan internet pada perusahaan tidak selalu memberikan akses internet yang baik ketika user bekerja dengan internet. Tujuan penelitian ini menyelesaikan masalah pada jaringan di PT. Eka Bogainti; Penggunaan bandwitdth yang tidak tepat, mengganggu proses keberlangsungan bisnis perusahaan, belum adanya management bandwidth sehingga pembagian bandwidth tidak merata pada semua client. Metode membagi dan menyebarkan bandwidth secara bertingkat Hierarchical Token Bucket (HTB) yang diterapkan berjalan lancar dan dapat meminimalisasi terjadinya bandwidth lebih pada pengguna jaringan yang berakibat down pada jaringan. Hasil nya kegiatan operasional perusahaan dapat tetap berjalan lancar. Administrator jaringan dapat menentukan prioritas pengguna jaringan internet pada perusahaan sehingga management bandwidth lebih teratur. Diperlukan perusahaan meng-Upgrade perangkat keras maupun perangkat lunak dengan spesifikasi update untuk mengimbangi jaringan yang telah diatur menjadi sesuai dengan kebutuhan sehingga meningkatkan kualitas kerja para karyawan.]]>

<![CDATA[A computer network is of course very much needed by an institution or company to be able to exchange data or do work, especially on the internet network, so not a few companies or institutions have more than one internet subscription to a service provider. However, in reality the rented internet does not automatically replace or switch on the internet that turns off, sometimes you have to move ports and configurations so that trouble occurs when users access the internet and disrupt work. Using netwatch which is a method on the network to avoid connection down time. Used if the company has more than 1 internet source. The way it works is to make the backup of the second line automatically run if the main line dies. However, the problem is when the connection from the ISP (Internet Service Provider) to the internet is interrupted, while the company's MikroTik router can still be connected, so the router will read that there is still a connection and will not change the router's connection to the backup path. By using netwatch which is one of the features of MikroTik, it functions to monitor a host's condition at certain intervals. Netwatch works by periodically sending ICMP messages to the intended host, in this case it can send it to an internet host that is definitely always on. A down connection from the ISP will read down so that the router will automatically change the connection using the backup path.]]>
