The purpose of this research was to know The Effect of Differences feeding time of Natural Feed Artemia sp. and Water Flea on the Growth and Survival of Giant Gouramy Larvae (Osphronemus gouramy, Lac). This research used the experimental method, while the experimental design that was used completely randomized design (CRD) with five treatments and three replication. The treatments in this research ware P1 (giving Artemia sp. for 10 days and 30 days for Water Flea), P2 (giving Artemia sp. for 20 days and 20 days for Water Flea), P3 (giving Artemia sp. for 30 days and 10 days for Water Flea), P4 (giving Artemia sp. for 40 days), P5 (giving Water Flea for 40 days).The result showed the best treatment was feeding with P5 (Giving Water Flea for 40 days) the growth of absolute weigh that produces 0,086 grams, the growth of absolute len...

Some electronic media reported the impact felt by the fishermen of Buluh Island on the shipyard industry and farm of pig activities. This study aims to maintain the quality of the aquatic environment on Batam City's Buluh Island through the modeling of sources of scattered waste, so a study of non-point pollution is needed that has a direct impact on people's lives. Material and Methods: BOD parameters, in general are widely used to determine the level of waste water pollution. BOD measurement is a measurement of the amount of oxygen used by microorganisms in decomposing organic matter that is in a waters. Decomposition of organic matter involves various organisms and oxidation reactions occur with the end result of carbon dioxide (CO2) and water (H2O). Oxidation reactions during the BOD examination are the result of biological activity and the reactions that take place are influenced by the population and temperature. This research was conducted in the Buluh Island area, Bulang District, Batam City, Riau Islands Province. This research was conducted in April-June 2019. The location of the study was Buluh Island, where there were many shipyards and pigs which were thought to be a source of waste distributed in the marine waters of the island of Batam City. Sampling is done based on the station (5 stations) that have been determined and measured in the laboratory and compared with the results of the model using equation 1. Results: Based on the results obtained at the five stations both for measurement results and modeling results (calculation results) BOD concentration values the highest is at station-3 and station-5 with values 16,978 and mg / L.

The result showed the best treatment was feeding with P5 (Giving Water Flea for 40 days) the growth of absolute weigh that produces 0,086 grams, the growth of absolute length is 0,831 cm, the daily growth rate of 4,332 %. The water quality parameters during research were temperature 26,4-27,8 ºC, pH 6,5-7,3 and dissolved oxygen 4,0-6,0 ppm.
