Abstract

The abundant wealth that Indonesia has is very profitable. Wealth is not only from natural resources, but wealth or biodiversity is also able to make Indonesia an independent country in managing its environment. One of the varieties that can be utilized is the existence of aquatic plants that can be used in the restoration of polluted environments. The ability of plants to recover from pollutants is called phytoremediation. Hexavalent chromium/ Cr(IV) is a hazardous waste originating from the washing of ore/open pit waste from rainwater washing. The quality standard allowed for Cr (IV), according to the Minister of Environment Regulation No. 9 of 2006, concerning the Quality Standard of Wastewater for Nickel Ore Mining Businesses and/or Activities is 0.1 mg/L. Besides being used to reduce pollutant loads, this aquatic plant can also provide aesthetic value because it has a very beautiful shape, type, color, and flowers. The purpose of this research is to find out which plants can be used to reduce hexavalent chromium levels. Variations of aquatic plants that can reduce levels of hexavalent chromium which are harmful to living things include water hyacinth/Eichornia crassipes; water hyacinth; Kayambang/ Salvinia Cucullata; Kiambang/ Apu Wood/ Pistia Stratiotes; Hydrilla verticillata; Water Bamboo/Equisetum hyemale; Water spinach / Ipomoea Aquatica; and Sagittaria lancifolia. This aquatic plant can reduce Cr (IV) up to 99.5%. The ability of these aquatic plants not only to reduce Cr (IV) but also to reduce TSS, BOD, and COD and to neutralize pH. The combination of several aquatic plants also provides a high effectiveness value.

Abstract

The Sukaregang leather tanning industry has grown rapidly since the 1920s. Currently, there are an estimated 300 home-based leather craft industries in this area. This study attempts to examine the spread of chromium from the Sukaregang leather tanning industry in the surrounding soil. The research was conducted using a model. From the results of the chromium dispersion model simulation, zoning of groundwater pollution around the industry will be obtained, which will be useful for the local government in formulating a concept for pollutant control. The input for the modeling is geological data, morphology, hydraulic conductivity, groundwater level data, and chemical data on wastewater and groundwater. To that end, geophysical measurements, drilling and pumping tests, wastewater and groundwater sampling, and chemical analysis were carried out. In the Sukaregang Industrial Area, there are three wastewater treatment plants (IPAL) for around 300 household industries that produce an average of 900 m3/day of wastewater. Of the three IPALs, only one is operational. Chemical analysis of wastewater samples from tanning processes in groundwater revealed the presence of chromium. Modeling results indicate that groundwater flows northward.
