Abstract
Background and Purpose: The large number of shipyard industrial activities that stand
around Buluh Island has the potential to pollute the waters of the island of Buluh so
that it impacts on the catches of the reed island fishermen themselves. 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.17, 986 mg / L. This is
because the station is the main source of waste in the farm of pigs and the location of
the largest shipyard in the study area which has an impact on the decline in catches of
Batam Island's Buluh fishermen. Conclusion: Based on the analysis conducted in this
study, it can be concluded that by using the equation of the distribution model of
scattered limbs and some physical parameters such as current speed, distance,
coordinates and some water samples at each station, it is very easy to map the
BOD-wide waste distribution model in Buluh Island waters. Batam City, Riau Islands
