The world has changed a lot in the last couple of decades. Instead of simply dealing with local or regional concerns, many businesses now have to think about global markets and logistics. Many companies have facilities spread out across the country or around the world, and there is one thing that all of them need a way to maintain fast, secure and reliable communications wherever their offices are. Until fairly recently, this has meant the use of leased lines to maintain a wide area network (WAN). A WAN had obvious advantages over a public network like the Internet when it came to reliability, performance and security. But maintaining a WAN, particularly when using leased lines can become quite expensive and often rises in cost as the distance between the offices increases. As the popularity of the Internet grew, businesses turned to it as a means of extending their own networks. First came Intranets, which are password-protected sites designed for use only by company employees. Now, many companies are creating their own VPN (virtual private network) to accommodate the needs of remote employees and distant offices.

Virtual private networks (VPN) and IPsec are discussed in this chapter. A VPN emulates a private wide area network (WAN) facility using IP networks, such as the public Internet or private IP backbones. When VPNs are used, the Internet offers the appearance, functionality, and usefulness of a dedicated private network. One of the problems in using the Internet as a WAN is that the Internet is a public network and has relatively little security. IPsec provides the following security services to VPNs: data origin authentication, access control, confidentiality (encryption), connectionless integrity, rejection of replayed packets (a form of partial sequence integrity), and limited traffic flow confidentiality.

A Software-Defined Network (SDN) on a Wide Area Network (WAN) is a computer network that is controlled and created by software. SD-WAN is an emerging research area that has received a lot of attention from industry and government. This technology offers tremendous opportunities to support the creation of consolidated data centers and secure networks. This is an innovation that allows the network to be monitored and programmed so that it can respond to network events caused by security breaches. This solution provides network security, offers a single network management console, and provides complete control over the network architecture. Also controls security in the cloud software-defined infrastructure (SDI), such as dynamically changing the network configuration when forwarding packets, blocking, redirecting, changing Media Access Control (MAC) or Internet Protocol (IP) addresses, limiting the packet flow rate etc. Using SD-WAN technology, it is possible to reduce the cost of dedicated bandwidth channels, achieve a high-quality Virtual Private Network (VPN), and the ability to automatically select a channel for certain channels. The main advantages of SD-WAN are the management of an unlimited number of devices from a single center, reducing the cost of deploying branch infrastructure. According to the results of the survey, 7 % of respondents use SD-WAN for security solutions, 14% at the piloting stage. As a result of the research, it was revealed that by 2024, to increase the flexibility and support of cloud applications, more than 60 % of SD-WAN customers will implement the SASE (Secure Access Service Edge) architecture, which is 30% more than in 2020 and the main concept - application security and cloud functions.

<p align="center"><strong>ABSTRACT</strong></p><p><em>The internet as a data transmission backbone has security threats in sending data. To overcome the security problem of every data communication that is done through a public network (public network), then a connection is needed that requires a connection between workstations running privately, so that only workstations that have access can connect, by using a virtual private network or VPN. The advantage of a VPN is that data sent over an encrypted VPN is quite safe and the secret is maintained even through the internet network because the data sent will go through the tunnel. Tunneling itself is a method for transferring data from one network to another by using a veiled internet network. Two protocols can be chosen in a VPN, namely Point to Point Tunneling Protocol (PPTP) and Layer 2 Tunneling Protocol (L2TP). However, the performance of each of these protocols is unknown yet. To find out the performance of the two protocols we need a test with a simulation method. Using a Mikrotik router and Wireshark application with Quality of Service (QoS) parameters consisting of Packet Loss, Delay, and Throughput on 2 clients connected to the mikrotik router and each client uses a different protocol. All clients will stream videos simultaneously to get a data packet capture. The test results will be grouped into four categories, namely bad, moderate, good and very good. It is expected that data will be able to show the quality of service of both protocols. so that it can be used as a reference in the selection of VPN protocol to be used.</em></p><p><strong><em>Keywords: </em></strong><em>Quality of Service, PPTP, L2TP</em></p><p align="center"><strong>ABSTRAK</strong></p><p><em>Internet sebagai backbone pengiriman data memiliki ancaman keamanan dalam pengiriman data.

The need to access data remotely is a person's need to be more efficient in doing a job. Currently there are many remote access application programs, one of which is TeamViewer by utilizing the internet public network. By installing a TeamViewer program on a client and server computer someone can do data work and repair remotely as long as it is connected to the internet. To be able to do remote access, of course, a client must already know the user and password from the server computer. The disadvantage of TeamViewer is that other people will easily remote access data simply by entering the user and password that the computer has on the server. To overcome this problem, VPN technology is used with the PPTP protocol where only the IP address of the client that has been registered on the proxy device can access data on the server. VPN allows clients to connect to the server privately through public networks. To find out the performance of the VPN network that is built, QoS (Quality of Service) parameter analysis is needed which includes delay, jitter, throughput and packet loss. From the results of the tests carried out, the results of QOS with an index of 3.75, which if converted to the standard TIPHON, VPN network at STMIK STIKOM Indonesia has a satisfactory quality.

One of the ways to maintain and improve the quality of service and security on the network of an agency of the Barangin Sub-District Office, Sawahlunto City (Central) is to add a VPN feature. Administrators who always monitor the flow of traffic by accessing routers and access points to find out network conditions. There are times when the Administrator is on a public network, he or she cannot access routers and access point devices because the Public IP obtained is Dynamic (random). To solve this problem, it is done through the Network Development Life Cycle (NDLC) method by combining the L2TP and IPsec VPN protocol systems on Mikrotik. A Virtual Private Network (VPN) is a private and secure network using a public network such as the internet. One of the bases for securing VPN technology is Internet Protocol Security (IPSec). IPSec is a protocol used to secure datagram transmission on TCP/IP-based networks. This study aims to design and implement a VPN network system by utilizing a public network, where this system provides advanced security enhancements on the internet network using IPSec. The information/data sent will be confidential with an automatic encryption method through the L2TP tunnel method from the server to the branch/client computer and vice versa. The VPN is implemented using a layer 2 (L2TP) tunneling protocol using two Mikrotik routers. There are few changes to the computer network configuration to minimize costs and implementation time. Tests are carried out to implement security on the network using the command prompt, where the admin observes packet loss and delay parameters to determine the increase in security quality on the network.

Practicum registration systems that exist on campus STTA previously done manually, where students will sign up to the admin to bring proof of payment practicum. Students are free to choose his own class, this often resulted in unbalanced number of students in the classroom lab that is consideredless  effective way. This makes the emergence of the idea to establish an MM algorithm is applied to a practical application o f automation systems. MM algorithm works by determining many lab classes based on students who took the KRS. Furthermore, students who have paid practicum will be immediately incorporated into the classes that are available with regard to the number of students and GPA o f students per class, so it will obtain practical classes by the number o f students and the average GPA o f each class balanced.Concept application using client-server database, where the database is on the Local Area Network (LAN) STTA. To facilitate the management admin, then the application will be tested on the LAN network and VPN (Virtual Private Network) network. LAN is a computers network that are connected to a computer server by using specific topologies, typically used in areas of the building or area a distance o f not more than 1 km (local area). While VPN is a secure way to access the Local Area Network that is in range, using the Internet or other public network to perform packet data transmission in private. By using a VPN, users can access the computer that is on the LAN even though the user is not in the same location with a LAN.

The use of information technology and its use in collecting and processing data into information that is useful in decision making will play a role in determining the success of an organization or company in the future. This happened to PT. Jasa Cendekia Indonesia, the computer network that is owned has not met the needs of its employees. A good computer network is one that can serve sharing resources, data security, resources more efficiently and up-to-date information. Basically if a company can hold a computer network that serves the above for employees, of course it will make it easier for employees to do the work and improve the standards of the company itself. The proposed network built by the author for PT. Indonesian Scholar Services is a computer network built with Virtual Private Network technology. Because companies that have communication between the head office and branches that are good and safe, will be the capital for their companies in facing challenges in the era of globalization. Communication that is connected to a fast and secure computer network will make it easier for a company to supervise the activities of its company.

Dalam dunia bisnis, biasanya sebuah organisasi ingin membangun Wide Area Network (WAN) untuk menghubungkan beberapa kantor cabangnya. Sebelum munculnya Virtual Private Network (VPN), mereka umumnya menggunakan ” leased line” yang mahal sehingga hanya perusahaan besar yang dapat memilikinya.VPN - WAN memberi solusi alternatif karena dapat mengurangi biaya pembuatan infrastruktur jaringan dan memotong biaya operasional dengan memanfaatkan failitas internet sebagai media komunikasinya. Perusahaan cukup menghubungi Internet Service Provider (ISP) terdekat untuk mendapatkan layanan ini.Setiap paket informasi yang dikirim dapat diakses, diawasi atau bahkan dimanipulasi oleh pengguna. Supaya komunikasi berjalan aman maka diperlukan protokol tambahan khusus yang dirancang untuk mengamankan data yang dikirim. Dewasa ini sudah banyak perusahaan seperti : perusahaan manufaktur, distribusi dan retail; pertambangan minyak dan gas, telekomunikasi, finansial, pemerintahan serta industri transportasi yang menggunakan VPN karena fasilitas –fasilitas yang ditawarkan berupa remote access client, internetworking LAN to LAN serta akses yang terkontrol dengan biaya yang murah. Uji coba yang dilakukan Miercom(LAB penyedia testing kinerja perangkat keras) terhadap Cisco 1841 membuktikan bahwa Cisco 1841 dapat menopang suatu komunikasi dua arah, interkoneksi IP WAN kapasitas E1 dengan enkripsi 3DES yang dapat menunjang throughput sampai dengan 2 Mbps dalam koneksi E1 IP-WAN. Penggunaan VPN akan meningkatkan efektivitas, efisiensi kerja serta skalabilitas perusahaan. Keuntungan lain yang didapat dari VPN adalah pada biaya pulsa yang jauh lebih murah dibandingkan dengan menggunakan” leased line”.
