Internet OFFLINE: Manajemen Operasi Internet OFFLINE

Offline Internet Framework The Offline Internet Framework was developed for the first time and presented on youtube on the OnnoCenter Channel at https://www.youtube.com/watch?v=cKuiRIQMZFE entitled "Offline Internet Concept for Schools" dated 1/10/2018.

In general, there are three (3) functions / sections, namely, (1) content controller and accumulator, (2) Operation of Offline Internet facilities at school, and (3) students / teachers who are accessing the content using smartphones / computers.

The content collection section that may be centralized and performed by authoritative body, the content collected in an SD / microsd card and ready to run. Content is then distributed to schools, and installed on a local RaspberryPi server. Teachers and students can access through local network facilities such as LAN and WiFi. Preliminary Development Initial development has been self-financially started by the author. Moreover, the results are freely released online and, thus, the Indonesian may immediately received the benefit from the technology.

In general, there are three (3) functions of Internet Offline System that must be considered, and developed, namely.

   1. Content collector / controller / accumulator, as well as distributor to schools.
   2. Offline Internet infrastructure at schools
   3. Users mostly students / teachers who access the content via smartphones / computers.

In content collector / controller / accumulator , some of the tasks are as follows

   • Determine which content / web need to retrieved based on the school's curriculum.
   • Content will be limited to the size of microsd. The average affordable microsd has around 8-16 Gbyte space, which be used for a  lot of text content. But not much lots of video content.
   • Content should be adjusted to the school's curriculum. This is a bit difficult as content for grade 1 will definitely be different from other classes. Hence, more research is needed to do in depth content analysis.
   • Content should be adjusted to the teaching methods. As far as I know, there is currently no standard on the teaching materials / methods on using online materials. Not many education faculties provide practical method to maximize online teaching material in the learning process. Thus, teacher’s  creativity is required to maximize the benefits of existing content. 
   • Technologically, the process of copying material to make it available offline is relatively simple, even the Wikipedia community has provided kiwix for these purposes.

In the operation of Internet Offline facilities at schools, some of the tasks are as follows

   • This work is focused on preparing the Offline Internet server using embedded system, such as raspberrypi or orangepi.
   • The technical aspects are written in more detailed in the wiki http://onnocenter.or.id/wiki/index.php/Internet_offline [9]
   • In general, Raspberrypi Server is prepared to act as a stand alone server with Web Server facilities, DHCP Server, File Sharing Server, DNS Server so that it can function as an Offline Internet server.
   • The BIND DNS Server is set according to the machine domain that is copied to redirect traffic not to the Internet but to the local server.
   • Apache Web Server is set to be a virtual hosting server that is capable of receiving HTTP and HTTPS traffic.
   • Kiwix is used to display copy of Indonesian wikipedia and wikitionary copies. Users may access it via the Web.

Students / teachers accessing the content via smartphone / computer may have several notes, such as,

   • Smartphones, tablets, laptops may be used to access available teaching materials. We only need to provide additional WiFi Access Points and LAN cables. A single WiFi Access Point will only effective for a maximum of  ten (10) simultaneous devices. To be able to be simultaneously accessed by the whole school, many WiFi access points with many channels that are different from each other (orthogonal channel) are needed
   • The biggest problem is the electricity power to keep smartphones, tablets and laptops running for a long period of time.
