The aquaculture world is one of the fields of Aquaculture business that is quite attractive to many in Indonesia. the commodity produced varies in each region. Conventionally, ponds are made by dredging land and must use land that is relatively large and not small in cost. However, now there are many ways that allow people to farm on relatively narrow land with more affordable costs for many who want to start a business in the field of aquaculture, one of them is by using a round pond system.

A round pool is a pond on the ground whose frame is formed using iron Wire mesh and plastic as its protective base. Common commodities cultivated by using a round pool as a medium for farming are fish and shrimp. At present, many round pool users use Tarpaulins as the base of their round ponds, whereas Tarpaulin use is very risky for the quality of the pond's commodity being cultivated so that the transfer of use from tarp to Geomembrane is one of the best solutions available. PT Kencana Tiara Gemilang (KTG) provided the solution with its Geomembrane production which has quality assurance and International standard certificates for safer and more durable round pools. The following are the advantages of using KTG Geomembrane for round pool applications:

1. The coating that is not easily peeled off
KTG geomembrane has a smooth surface and is not coated by lamination, this makes no surface part of the KTG Geomembrane exfoliated when used in a round pond so that water quality and commodities being cultivated will be safe from pollution. Unlike when using a tarpaulin that has a laminate layer, within a certain period of time the laminate layer will be able to peel off and cause debris in the round pond. The chipped flakes will contaminate the water in the round pond and will endanger the commodity being cultivated in the round pond. And if the chips are consumed by fish or shrimp, it will be very dangerous if it is consumed again by humans.

2. More Durable Products
Because it has guaranteed quality advantages with international standard certificates, KTG Geomembrane has a product life span of up to more than 10 years of service life, in contrast to tarpaulins with very short usage life. This will have an impact on the operational costs incurred more when using tarpaulins in round pools.

3. Avoid the risk of leaks
Because KTG Geomembrane is made of pure plastic material, it makes the quality and strength that is produced is maintained. The strength that is one of the superior, makes KTG Geomembrane impermeable to water so that the round pool will avoid leakage. Tarpaulins that have a woven form will make the risk of leakage high, in addition to endangering the commodity being cultivated, the risk of high leakage will have an impact on the farmer who will spend more energy and costs in the round pond maintenance process.

4. Product Resistance to Temperature
The main enemy of plastic is heat and temperature that changes in extreme ways. KTG has conducted various lab and field tests with International standard certificates for each Geomembrane produced. KTG geomembrane is also applied to the larger scale aquaculture business such as shrimp farms. Djunaedi is one of the managers of shrimp farms in Pasuruan who have used KTG Geomembrane for 3 years. During the use of the KTG Geomembrane, Djunaedi did not encounter any obstacles which meant that because of the quality of KTG Geomembrane which has been proven to be able to withstand solar and UV light, KTG Geomembrane is also resistant to extreme temperature changes. With evidence of KTG Geomembrane resistance in larger aquaculture businesses, KTG Geomembrane will also be suitable and will last longer in round ponds. Quality will be maintained for a longer period of time and not easily weathered compared to round ponds that use tarps, so it will be more profitable for farmers because it saves the cost of round pool maintenance.

5. Easier Pool Care
Because the surface is flat and tight, making KTG Geomembrane easier for the treatment process, especially when cleaning round pools. The KTG Geomembrane cleaning process only needs to be sprayed with water and then dried, the release and installation of KTG Geomembrane in the circular pool frame is also very easy. Unlike when round pools use tarps as a media base. The process of cleaning the tarpaulin will be more difficult because it must be rubbed on the surface. The scrubbing process is also at risk of causing a layer of lamination to fall on the tarpaulin. The loss of the laminate layer, besides being able to reduce product age and durability of the tarpaulin, will also be dangerous for commodities that are being cultivated because the laminated debris that can fall off can contaminate the water in the circular pool which impacts on the quality of the commodity inside.

6. Cheaper Costs
At a glance, the cost of making a round pool with KTG Geomembrane will be more expensive than using a tarpaulin. In addition, round pool treatments that use KTG Geomembrane are easier, which will reduce the cost of round pool maintenance. Geomembrane offers more efficiency and cost-effectiveness in the aquaculture process. The cost of a high round geomembrane pond with a longer service life than tarpaulin use will greatly save capital and cost usage in the long term, at least for 2 (two) cultivation seasons (based on fish farm information in Madura).

From the explanation above, the use of tarps in round pool media does not mean that it is a wrong step, but replacing the use of tarpaulin into KTG Geomembrane will be a better step because it will benefit farmers and farmers a lot. The benefits can be obtained not only in terms of the efficiency of operational costs and maintenance, but also the energy that is spent will be more minimal because the process of KTG Geomembrane maintenance in round ponds is easier, so the profit turnover can even increase.

So, it's time to use a geomembrane as a coating on a round pond rather than using a tarpaulin. Lots of advantages and advantages offered by geomembrane. If you want to get maximum yields and lower operating costs, it's right if you use geomembrane.
