“…These free radicals can inhibit the work of enzymes, damaging membranes and pigmentation, such as chlorophyll [14]. Disruption of various activities in chlorophyll can also affect the production of rice plants such as decreasing dry weight of rice plants and reducing the number of rice grains [7].…”

Leather tanning industries in Sukaregang area, Garut district-West Java, have been using chromium since 1980s. Since that time chromium containing wastewater has been polluting river water in the area since there has not been effective waste water treatment available until today. The polluted river water spread bad smell to the environment and the water also has been used by local farmers to irrigate their paddy field. This research was conducted to examine the effect of chromium containing wastewater to growth of paddy, including the physiology stress in plant organs. For examination of the effect of chromium to plant growth, Ciherang variety (Cvar) of paddy was grown in soil and treated with chemical solutions of K2Cr2O7 with concentrations of 50, 100, 200 mg/L, polluted river water (PRW) and distilled water as a control. Direct exposure of chromium 100-200 mg/L killed the plants a week after treatment. Exposure of the plant to wastewater and chromium 50 mg/L reduced plants growth. In Cr 50 mg/L treatment, chlorophyll content in paddy decreased to 60.82%, while the proline concentration in leaves increased by 18.47%. The activity of CAT and APX enzymes also increased, especially in paddy leaves after treated with Cr 50 mg/L, with the highest CAT activity value reached 1990.31 units/mg (an increase of 76.76%) and APX activity of 59.91 units/mg (an increase of 81.02%). The effect of chromium-containing wastewater to paddy was similar to the effect when the plant was exposed to 50 mg/L of chromium.

This causes a decrease in their rice production, IOP Publishing doi:10.1088/1755-1315/1034/1/012055 2 but so far the pollution still continue as the wastewater treatment units have not been working properly [7].…”

“…The polluted river water (PRW) has been used by local farmers to irrigate their paddy fields. According to our previous report, the use of PRW for watering the paddy field reduced the productivity of paddy field and chromium was accumulated in paddy grains of Rojolele variety (Rvar) and Sarinah variety (Svar) in relatively high concentration [5].…”

In leather tannery industry such as a case in Sukaregang, Garut, untreated or poorly treated wastewater which contain chromium has been severely polluting nearby river. The polluted river water (PRW) has been used by local farmers to irrigate their paddy fields. In this study we planted Sarinah variety (Svar) and Rojolele variety (Rvar) of paddy in soil and watered with PRW, K2Cr2O7 solutions with concentration of 50 and 100 mg/L and clean water as a control, for a period of four months. Chromium solutions were added gradually to the soil until reached final concentrations of 50 and 100 mg/L. The result showed that the treatment with PRW and Cr solutions reduced plants weight, shoot length and paddy production. Treatment with Cr solutions significantly decreased plants fresh and dry weight by 26.53% and 36.69% for Svar, 32.14% and 19.74% for Rvar. Paddy yield also decreased as higher Cr concentration was accumulated in plant tissues. The amount of filled grains decreased by 33.05%, while empty grains increased by 50.21% in Svar. In Rvar the amount of filled grains decreased by 21.44% and empty grains increased by 31.95%. Chromium treatment by gradual increase allowed plant to survive at an exposure of 100 ppm Cr, although the plant reduced its growth, biomass and yield.
