Abstract

Mayang River in Jember Regency has a strategic role in fulfilling people's lives and is a source of water for 79 irrigation areas with a total area of 16,471 hectares. Community use of the Mayang River has the potential to provide input of organic material from waste which can reduce river water quality. The aim of this research is to analyze the spatial distribution of water quality parameters, namely TSS, TDS, pH, DO and BOD. This research uses multiple linear regression techniques to determine the value of the distribution or spatial distribution of Mayang River pollution, as well as identifying water quality variables that are correlated in each region. The research results show that water quality parameters that have a strong correlation are pH (r = 0.74), DO (r = 0.72) and TSS (r = 0.65), moderate correlation with BOD parameters (r = 0.48) and low correlation with BOD parameters. TDS parameters (r = 0.25). Based on the analysis results, it is known that water quality parameters are correlated with different activities in each region. The results of this research can be used as a strategy for monitoring water quality in the Mayang River to control the impact of human activities in the surrounding area. Keywords: Multiple Linear Regression, Spatial Distribution, Water Quality.

Abstract

Coffee processing wastewater originating from the coffee agroindustry has the potential to reduce environmental quality. Water hyacinth is one of the biological agents capable of reducing pollutants in wastewater through a rhizo-filtration mechanism in the phytoremediation process. The pollutant reducing ability of water hyacinth is limited so that the replacement of water hyacinth is one of the alternatives for optimizing the phytoremediation method. The purpose of this research was to compare the replacement time of water hyacinth to the decrease parameters namely turbidity, Biochemicals Oxygen Demand (BOD), Chemicals Oxygen Demand (COD), ammonia, and phosphate in the treatment of coffee processing wastewater using the phytoremediation method. The research stages consisted of water hyacinth acclimatization, determination of hydraulic resistance time, water hyacinth replacement time, and analysis of wastewater pollutant reduction. The density of water hyacinth used is 30 grams / L and the incubation time is 14 days. The results showed that the replacement of water hyacinth had a positive effect on improving the quality of coffee processing wastewater. The most water hyacinth replacement was on the 7th day. The percentage of turbidity parameters, Biochemicals Oxygen Demand (BOD), Chemicals Oxygen Demand (COD), ammonia (NH3-N), and phosphate (PO4-P) in the treatment of coffee processing wastewater with replacement of water hyacinth sequentially is 92.02%; 81.10%; 81.05%; 76.03% and 72.40%.

Abstract

Water quality is a key indicator related to the sustainability of living things in a watershed. However, human activities have led to a decline in the water quality caused by industrial, domestic and agricultural waste. This study aims to predict the pattern of TDS parameters at unsampled points through a geostatistical approach, namely Kriging. Experimental measuements were conducted in the Bedadung River, Jember Regency, especially in a segment of Patrang to Wuluhan sub-districts. Currently, the river is classified as Class 3, which is below the standard, one of the water quality parameters is TDS (Total Dissolved Solid). The TDS estimation results were obtained in the range of 48.26 mg/L - 175.52 mg/L. The predicted value of TDS using the kriging method at unsampled points resulted in an RRMSE value of 8.40 %. This study revealed that the water quality of Bedadung River from Patrang to Wuluhan sub-districts was still below Class 2 standards, emphasizing the need for continuous monitoring and improvement efforts. Keywords: Ordinary kriging, River water quality, Semivariogram, Total dissolved solid.
