Implementation of biofloc technology (BFT) system in aquaculture industry shows high productivity, low feed conversion ratio, and an optimum culture environment. This study was divided into two phases. The first phase involved maintaining the water quality using carbon-to-nitrogen ratio by manipulating pH water. second examined performance harvesting (remaining phytoplankton suspended solids system) chicken eggshell powder (CESP). showed that 7 to 8 were best with removal percentage ammonia...

The study aimed to address the critical problem of malathion pesticide contamination in agricultural runoff and its adverse impact on environment. It specifically focused utilizing granular activated carbon (GAC), derived from both coal (CBAC) peat (PBAC), as a promising solution for effective removal. This substantial influence particle size GAC dosage removal efficiency malathion. was determined that optimal conditions, resulting an impressive 90% efficiency, were achieved when initial...

Lake is one of the complete ecosystems and source freshwater itself. serves as a habitat for aquatic plants animals, including microorganisms. can either be formed naturally or manmade. Most lakes are from volcanic eruptions, cave ruins rainwater. Man-made usually after mining activities, many found all over world. Water pollution, lake common worldwide. It point-source non-point source. Natural environmental factors also contribute to pollution. In this study, life has been dead samples...
