Abstract

The Bengawan Solo River stretches from the Central Java region to East Java, making it the longest river on the island of Java, where Bengawan Solo has become the economic pulse for residents, especially in Central and East Java, which crosses trade, office areas, densely populated settlements, and industries. These various activities produce waste, which has an impact on water quality pollution. The purpose of this study aims to determine the status of the water quality standard of the Bengawan Solo River. Data used from the Solo Bengawan River Basin by using data from the January-March 2020 period through 12 monitoring points were analyzed using the STORET Method. Each parameter is analyzed using Peraturan Pemerintah no. 82 Tahun 2001 and the results most of the parameters did not meet the quality standards, including TDS, TSS, DO, Nitrite, Phosphate, COD, BOD, Lead, Copper, Total Coliform and Fecal Coliform. The results of the STORET assessment analysis show that the Bengawan Solo River is included in class 4 by 41.6% in moderate polluted conditions and the remaining 58.4% in heavily polluted conditions. The STORET Method calculation results according to classes I, 2 and 3 are 100% points in Poor condition (≥-30) which is a heavily polluted condition indicating the status of water quality is not in accordance with the standard applied by Keputusan Gubernur Jawa Timur No 61 concerning river use in East Java.

Abstract

Every process of industrial activity generates potential waste as air pollutants. Air pollution needs to be analyzed to estimate the magnitude of the risk posed. The purpose of this study was to investigate environmental health risks in exposure to SO2, NO2, NH3, and dust gases for workers in Surabaya, Gresik, and Sidoarjo. The method of this research is by collecting secondary data was obtained from BBTKLPP Surabaya. The secondary data collected was calculated using the Environmental Health Risk Analysis (ARKL) method by finding the concentration value, the amount of intake, and the characteristics of the maximum and minimum health risks of each chemical agent in the air parameters in the work environment. The research results show that the concentrations of exposure to SO2, NO2, NH3, and dust in the safe category at the industrial centers of Surabaya, Gresik, and Sidoarjo for workers.
