Why Tracking the Online Business Matters?

The development of online business is now very rapidly, giving rise to a fairly tight business competition. But in the midst of competition that exists, not all traffic blog or website has a good visit. So that each online business has a track or a number of different visits.

To win the business competition online, many business people try to optimize their blogs or websites to find information about consumer visits. This has pushed the business online, want to know the tracking blog or website that they have today.

The benefits of tracking visitor activity, among others, online businesses can find out where visitors find their online business, how many consumers who visit your blog or website every day, how long visitors browsing on your blog or website, to the page or content of any The most frequently visited by consumers. So you know the important information regarding the development of your online business today.

If you are curious and wonder, why tracking is important in online business? here we provide the answer:

* By knowing how visitors found your online business (such as through a search engine Google with certain keywords), then you can focus on increasing the number of visits from this source. For example, by optimizing certain key words, on any existing content on your online business. Or it could also use SEO, to simplify the search process on the machine Google. So do not rule out the possibility, if your blog or website will appear on the first page of Google search results.
* Information on the number of visitors coming to your blog or website every day, is also very important to you. With this information, you know how crowded visitors your online business. For a growing number of visitors who come every day, it is also becoming more popular blogs or websites that you have.
* How long visitors browsing on your blog or website, indirectly provide an assessment on the content in it. If the content is in your blog or website is good, then the visitor will also not hesitate to linger browsing your place. This has become one consideration when you make an evaluation of content and  consumers, so you know how to improve visitor satisfaction.
* The fourth, the importance of tracking can assist you in determining the topics that consumers demand. By looking at the data content of the most frequently visited by consumers, you know the interest of consumers. So for the next topic, can be adjusted with the main interest of the visitors.

Knowing blog, is one of the things required for online businesses. Therefore, activity tracking is required to obtain data of a blog or website developments which impact on the progress of the business. So information about online business, may be able to help you that is running an online business. Regards success.

Sedimentation is the entry load of sediment into a certain aquatic environment through the medium of water and deposited in the environment. Sediment covering the soil and sand, berifat suspended, entering into water bodies due to erosion or flooding, and basically it is not toxic. Sediment in the water of suspended materials (Effendi, 2000). Sedimentation is basically a crust (regolith) is transported through hydrologic processes from one place to another, either vertically or horizontally. The entire surface of the seabed is covered by sediment particles are deposited slowly over a period millions of years (Garrison 2005, in Rianto 2010).

Sedimentary rocks or sedimentary rocks is one of the three main rock groups (along with igneous and metamorphosed rocks) are formed through three main ways: weathering of other rocks (clastic); deposition (deposition) due to biogenic activity, and precipitation (precipitation) of solution. Common types of rock such as limestone, sandstone, and clay, including in sedimentary rocks. Sedimentary rocks cover 75% of the earth’s surface. Pipkin (1977) states that sediment is the fraction, mineral, or organic material that ditransforkan from various sources and deposited by the media of air, wind, ice, or by airdan also includes material diendapakan of material floating in water or in the form of chemical solution .

The presence of sediment in water bodies lead to increased water turbidity which further inhibit the penetration of light and the transfer of oxygen from the atmosphere into the waters, also inhibits the view (visibility) aquatic organisms. Sediment can also lead to loss of suitable spawning place for fish. Sediment can cover the substrate so that organisms that require substrate as a place of life (such as periphyton) and as a shelter becomes impaired survival (Effendi, 2000).

Sources and Characteristics of Physical, Chemical, and Biological
According to Mero (1965), Sedimentation in coastal waters occurs slowly and held on for the supply of high sediment loads continue. Changes in sedimentation rate can occur when there is a change of physical environmental conditions in the watershed related. Land clearing increase surface erosion can increase the rate of sedimentation. Conversely, the construction of dams or diversion of river flow can change the condition of sedimentation into erosional conditions. When sedimentation solely because the charge transport of sediment along the coast, the rate of sedimentation that occurs relatively more slowly when compared with the sediment that gets loads of sediment supply from the mainland. The types of sediments can be divided into three groups to see where the source originated.

Sediment Lithogenous
This type of sediment derived from erosion of rocks on land. This can rejadi because of a physical condition ekstim fancy, such as those caused by heating and cooling processes danaynya of rocks that occur repeatedly in the desert, because of the dew-embundi winter, or due to chemical action of the solution materials contained in rainwater or groundwater to the surface of the stone.

Function of Coral Reefs

Coral reefs are:

* Shallow tropical marine ecosystems of the most complex and productive
* Ecosystems play an important role in global biogeochemical cycles
* Critical marine habitats that play a role in the sustainability of the earth ecosphere functions
* Spawning habitat, spawning, rearing children, and feeding ground for large numbers of organisms lau, especially those with important economic value
* Warehouse marine biodiversity
* Protective border & coastal coastal ecosystems other than malignant wave action and the destructive impact of hurricanes
* Advocates the existence of small islands around it
* Important source of bioactive materials necessary for human
* Records of natural variation in climate and environment of the past
* Recreational Vehicle
* Forum for the education

Benefits of Coral Reefs
In the economic context, coral reefs provide a number of benefits that can be grouped into two categories:

• Benefits of sustainable
 Fisheries offshore
 Fisheries coral
 Protection of beaches and small islands
 Marine Tourism
 Marinkultur
 Biotechnology
 Trade biota ornamental
 Areas of protection
 coral sand mining
 Crafts souvenirs
 Research and education

• Benefits that are not sustainable
 extractive activity
 Fishing with destructive methods
 Collection of reef organisms
 The illegal trade ornamental biota
 Development of coastal

The benefits of sustainable coral reef
• Fishing offshore

A variety of pelagic fish resources (eg, Scombridae, Exocoetidae, Carangidae, Charcharinidae) depend on coral reef ecosystems, either as the location of spawning, rearing children, and eating.
• Fisheries coral

groups of reef fish resources that are important to fishermen:

1. Fish, eg: Muraenidae, Serranidae, Holocentridae, Lutjanidae, etc..
2. Invertebrates, eg Gastropoda, Bivalva, crustaceans, Chepalopoda, Echinodermata, Coelenterata
3. Reptiles, eg, sea snakes and turtles
4. Makrofita, eg algae and seagrasses

Thresshold is a limit that can means of a transducer. Tresshold value can be used to see the difference in the number of swarms of fish and plankton in each thresshold tested. Usually used in conducting a study of 3 thresshold, typically used range of -80 dB: -75 dB: -70 dB. Estimated value is used to capture the target is estimated as the value of fish or plankton.

This method follows Longerwell (2004) which uses four threshold: -69 dB: -75 dB: -79 dB, and -85 dB. Duror (2004) mentions that the range of values ​​for the volume back scattering of zoo plankton (krill) at depths of 500-200 m for 120 kHz frequency of -92.75 dB to -73.49 dB, while for frequencies between 38 kHz to -86.75 dB to -62.64 dB.

Basically, the signal threshold is applied to remove the ‘noise’, which here means that unwanted signals generated by the echosounder, be it noise coming from the electrical equipment, acoustic echo or reverberation combination of non-target spescies plankton such as fish surveys in the case. Whatever the source, the sound echoes obscure the smaller the size you wish. When a signal is applied trheshold, each echo is smaller than the threshold is also ignored. Bias depends on the amplitude of the signal and noise ratio (SNR) (McLennan and Simmonds, 1992).

According to McLennan and Simmonds (1992), in favorable circumstances, which unthresholded echogram may show clear signs of a big fish scholls or againts the background of planktonic ignored. On the other hand, if the plankton dominate a complete echo echo integral, becomes more even though individually weaker than those from fish, well-selected threshold signal may be the only way to reject the plankton echoes. The survey, conducted in the tropics often a strong echo of plankton. This is less of a problem elsewhere, except for a short lives occasioanal bloom.

Weimer and Ehrenberg (1975) studied the simulation trheshold biased by signals from the distribution which is considered as a target strength .. When the SNR is 30 dB, the bias is about 25%. Foote et al (1986) perform similar calculations incorporate the measurement noise and target-empirical power function. The problem is more severe at higher frequencies when the acoustic absorption reduces the signal level at large distances. In this case, the function of steep amplies TGV (constant) background noise and signal-to-noise ratio is reduced.

Johanesson and Mitson (1983) propose alternatives to overcome the noise threshold signal in the echo-integration. Measurement of noise levels at the output with the echosounder transmitter is turned off. Furthermore, this estimate is reduced noise contribution of a complete echo-integral (ie, recorded without limits apply). This procedure does not allow for an echo, but has the advantage that the threshold bias eliminated or at least reduced, the noise in the echo-complete integral subject to random variation, but it should average to zero over a long period of integration. If the echo PDF target species are known, the threshold is calculated and a lot of bias correction can be applied to estimate abundance. Unfortunately, the true PDF is rarely known well enough for this purpose. The problem should be avoided if possible, using the ship calm or deep-towed transducer platforms for example.
