Summary: | One feature of mobile portal vidyanusa is reporting activities, this feature allows <br />
<br />
<br />
<br />
students to report their positive activities outside the classroom so that teachers can <br />
<br />
<br />
<br />
assess their activities outside the classroom. Recording activities using the camera <br />
<br />
<br />
<br />
feature on the smartphone, where the camera technology on the smartphone is <br />
<br />
<br />
<br />
increasing which resulted in the size of the image becomes larger because the resulting <br />
<br />
<br />
<br />
image resolution is greater. <br />
<br />
<br />
<br />
In Indonesia the distribution of information technology, especially bandwidth is not <br />
<br />
<br />
<br />
evenly distributed, there are many areas that have very low bandwidth so it takes a <br />
<br />
<br />
<br />
long time to perform the process of uploading photos. Therefore made compression <br />
<br />
<br />
<br />
system on mobile vidyanusa. <br />
<br />
<br />
<br />
In this study, the compression system was applied to mobile vidyanusa to help students <br />
<br />
<br />
<br />
report their fieldwork. Because the data transmitted has a smaller size thanks to the <br />
<br />
<br />
<br />
compression system. So students wherever they are may be able to report in the <br />
<br />
<br />
<br />
absence of barriers of low bandwidth. <br />
<br />
<br />
<br />
The compression system is classified into 2, ie lossless and lossy. This research will <br />
<br />
<br />
<br />
implement lossless because the capability will not reduce the quality. The deflate <br />
<br />
<br />
<br />
method will be used because this method is a combination of the sliding window <br />
<br />
<br />
<br />
compression method and the huffman coding compression method, so that the <br />
<br />
<br />
<br />
performance is better than both methods. <br />
<br />
<br />
<br />
In the experiments performed, this method resulted in an average compression ratio <br />
<br />
<br />
<br />
of 0.65. |
