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.

Jaringan komputer dapat dikatakan sebagai sebuah sistem yang terdiri dari berbagai komputer beserta resource-nya yang didesain agar dapat menggunakan sumber daya yang ada, sehingga dapat mengakses informasi yang diperlukan. Informasi tersebut dapat diakses melalui komputer yang lain dengan konsep computer networking, baik itu Local Area Network, Metropolitan Area Network, Wide Area Network ataupun juga internet. Untuk mengamankan suatu koneksi pada jaringan dapat menggunakan jaringan yang bersifat virtual yang dikenal dengan istilah Virtual Private Network (VPN).Virtual Private Network (VPN) adalah sebuah teknologi komunikasi yang memungkinkan untuk dapat terkoneksi ke jaringan publik dan menggunakannya untuk bergabung dengan jaringan lokal. Dengan cara tersebut maka akan didapatkan hak dan pengaturan yang sama seperti halnya berada didalam kantor atau network itu sendiri, walaupun sebenarnya menggunakan jaringan milik publik.UNIKOM sebagai salah satu perguruan tinggi yang dalam melakukan kegiatan operasionalnya terdiri dari beberapa stakeholder yang saling terhubung dalam jaringan komputer, perlu menerapkan konsep VPN untuk mengamankan informasi yang dimiliki pada suatu jaringan, ataupun untuk memudahkan dalam mengakses jaringan lokal yang ada di UNIKOM walaupun dalam mengaksesnya menggunakan jaringan yang bersifat public (internet).Hasil dari penelitian ini adalah berupa suatu rekomendasi dasar yang dapat digunakan oleh UNIKOM untuk menerapkan konsep Virtual Private Network (VPN) dalam pengembangan jaringan komputer yang dimiliki sehingga dalam pengaksesan informasi dapat berlangsung lebih aman dan efektif.

Network security is designed to protect the integrity, confidentiality and accessibility of computer networks and data using both software and hardware technologies. Every person, including organization requires a degree of network security solutions in place to protect it from the ever-growing landscape of cyber threats in the wild today.  This paper aims to design and implement TorVPN as an access point using Raspberry Pi in enhancing security and privacy in Local Area Network (LAN).  This access point was implemented by using the combination of The Onion Router (Tor) and Virtual Private Network (VPN) services. Then, the graphical user interface application was developed to assist and facilitate the user to access the network securely without having the difficulties to configure and install any software. To determine the effectiveness of the proposed work, there were two experiments involved in this study. Firstly, the confidentiality test which to verify its privacy in keeping the information securely. Secondly, the performance test of the Internet connectivity in terms of ping, download and upload speed. The encourage results was expected as the confidentiality tested on the TorVPN access point network has shown the positive outcome by securing client’s Internet data packet. While, the Internet connectivity is not stable enough, when the client’s IP address changed in the network. Hence, the combination VPN and Tor service using Raspberry Pi as an access point inside the LAN is suitable and secure the information in the network, but do not suggest for user who wants a good Internet connectivity.

As more and more applications find their way to the World Wide Web, security concerns have increased. Web applications are by nature somewhat public and therefore vulnerable to attack. Today it is the norm to visit Web sites where logins and passwords are required to navigate from one section of the site to another. This is much more so required in a Web application where data is being manipulated between secure internal networks and the Internet. Web applications, no matter what their functions are, should not exchange data over the Internet unless it is encrypted or at least digitally signed. Security should be extended to the private-public network borders to provide the same authentication, access control, and accounting services that local area network (LAN) based applications employ. The most widely used method of Web application security today is Private Key Infrastructure (PKI). Various examples of PKI implementations are examined.

A vertical flat-type bioreactor consisting of transparent polyethylene (food safe) was constructed, which is characterized by a flexible design and allows the adjustment of a light path of 1 cm – 8.5 cm and a working volume of 1.5 l – 4 l. To characterize the performance of the bioreactor, cultivation experiments were performed with the cyanobacterium Arthrospira platensis (AP). The growth was assessed continuously by monitoring optical density and intermittently by measuring the dry weight of the AP biomass. An on-line measurement technique for estimating biomass production rate in a photosynthetic microalgae culture was developed. The oxygen produced by AP in the culture medium was flushed out sparging using a mixture of air and CO2 (1%). Factors which might influence the AP growth were monitored: pH, temperature, oxygen concentration and the filling level were corrected automatically to compensate evaporation losses. As an example, the huge influence of the light intensity on the AP growth was tested. The increase of the photon flux density of 15 to 1200μmol/(l · d) led to a 22-fold increase of the productivity and a 3.1-fold shorter doubling time. Using an online measurement technique - together with the control of the growth process via a wireless local area network (WLAN) router and virtual private network - allows monitoring the growth of Arthrospira platensis remotely.

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.
