Abstract

Fishery in estuary make changes function of mangrove land and decreased, so that it affect water quality. This study aims to determine mangrove density and relation with the quality of wonorejo estuary waters. The method uses purposive random sampling and line plot method with a 10x10 meter plot to determine the criteria for mangrove density and water quality tests based on physic-chemical parameters and then correlated to test the effect. The results of the water quality analysis at the Wonorejo estuary with the optimum value at station 5 have an average parameter value of temperature (29°C), brightness (22 cm), current speed (0.083 m/s), TSS (55 mg/L), pH (7.36), salinity (5.5), DO (1.709 mg/L), COD (42.4 mg/L), nitrate (0.18 mg/L), and phosphate (1.045 mg/L). The criteria for mangrove density at each station include low density, medium density, and high dense density. Physic-chemical parameters related to mangrove density are temperature, brightness, salinity, and COD. Estuarine waters based on physic-chemical parameters, namely 40.3% salinity, 33.7% COD, 30.9% brightness, 30.8% temperature, 14% nitrate, 11.4% TSS, 8.1% current velocity, 1 .3% DO, and 0.1% phosphate affected by mangrove density.

Abstract

contains COD, TSS, PO4, and Total-N pollutants that can contaminate water bodies if the treatment process is not carried out first. In this study, the NPK fertilizer industry waste treatment was carried out using sequencing batch reactors (SBR) and granular activated carbon (GAC) by adding the coagulation-flocculation process as a pre-treatment so that wastewater can meet the established quality standards. In this study, the reactors were operated at HRT 12, 24, and 48 hours using a GAC mass concentration of 0.5, 1, and 2 g/L. The results show the highest reduction of COD parameters by 67%, TSS by 82%, PO4 by 45%, Total-N by 76%, optimal HRT by 48 hours, and an optimal GAC mass concentration of 2 g/L. The aeration rate is operated at 14 L/min, with a PAC concentration of 3 g/L being optimal.

Abstract

River water treatment uses a Sequencing Batch Reactor (SBR) with cassava peel adsorbents, meranti wood powder, and PAC. After going through the Sequencing Batch Reactor, (SBR), it will give disinfection to reduce the levels of E. Coli and total coliform in the water. It is expected to be able to set aside levels of turbidity, color, TDS, taste, odor, total coliform, E.Coli, nitrate, nitrite, hardness, and organic matter (KMnO4). The river water to be treated comes from the coagulation-flocculation process. Making variations of HRT and adsorbent. The hydraulic retention time variations compared were 6, 9, and 12 hours. There are 3 reactors with 1 control reactor, which includes a control reactor without adsorbent and one with PAC adsorbent. The conditions chosen at the reaction stage are aerobic. The removal efficiency of the color parameter is 8.4%, the total coliform parameter is 94.6%, the parameter e.coli 95.2%, the nitrate parameter is 52.6%, the nitrite parameter is 14.3%, and the organic matter parameter is 7.8%. At the same time, the parameters have increased by 2%. The best HRT in reducing pollutant levels in this study was 12 hours HRT for the SBR reactor with cassava peel adsorbent sowing placement, 6 hours HRT for the SBR reactor with meranti wood powder adsorbent sowing placement, and 6 hours HRT for the SBR reactor with top placement PAC adsorbent. The best effectiveness of the Sequencing Batch Reactor (SBR) in treating Kebon Agung River water is by adding meranti wood powder adsorbent by placing sprinklers
