Knowing about the ecological aspects involved in commercial breeding of aquatic organisms becomes an important tool to make aquaculture more productive and less impactful. Thus, periphyton taxon composition biomass on different substrates influence these water quality growth parameters Nile tilapia fingerlings were examined. An experiment with three treatments (substrates for periphyton: geomem...

Experiments are conducted to quantify leakage through a circular geomembrane (GMB) hole using two subgrades (underliners) not meeting modern filter criteria. Test results show that 1.9- and 5.0-fold increase in diameter causes 1.8- 6.2-fold leakage, respectively, whereas 2-fold GMB thickness an approximate 10% decrease leakage. For constant hydrostatic effective stress, 2- 3-fold water head abo...

The need for domestic salt every year has increased, both consumption and industrial salt. Some of the fisheries service programs include providing assistance to people's businesses, geomembrane, online marketing training. A large number farmers official work have caused implementation program be less than optimal, resulting in low production. This study uses a type-2 fuzzy method by integratin...
