Abstract

Industrial waste is a factor influencing the pollution of the Krueng Tamiang river. The purpose of this study was to analyze the level of water pollution in the Krueng Tamiang river with the parameters of Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD) and Total suspended Solid (TSS) parameters. The results showed the highest BOD parameter test results came from location 2 (Seumadam Bridge) of 3.63 mg / L at stage IV and the lowest BOD value at locations 1 and 6 (Kaloy Village and Alur Manis Bridge) at stage I of 2 mg / L. The highest COD parameter test results came from location 5 (Kota Lintang Bridge) of 21.0 mg / L at stage III and the lowest COD value at location location 1 (Kaloy Village) at stage III, points 1, 3 and 6 (Kaloy Village, Kebon Tengah Suspension Bridge and Alur Manis Bridge) at stage IV of 17.0 mg / L. The highest TSS parameter test results came from location 7 (Peukan Seuruway), namely 295 mg / L phase I in the dry season, and the lowest TSS value at location 1 (Kaloy Village), which was 11 mg / L in stage III during the rainy season.

Abstract

The aim of this study was to apply a biosorbent from the leaves of Lidah Mertua (Sansivieria sp.) which were activated by 4M HCl to remove mercury metal ions Hg(II). The leaves of Sansivieria sp. were cleaned, dried in an oven, and carbonized in a furnace at a temperature of 450 oC for 1.5 hours. After grinding to a size of 50 mesh, the resulting carbon was activated using 4 M HCl for 24 hours and dried at 110 oC for 2 hours. The absorption ability test of biosorbents was carried out by mixing 2, 3, and 4 grams activated biosorbent in 200 ml of water containing 0.15 mg-Hg/L metal ions Hg(II). The mixture was stirred using an incubator shaker with variated contact times of 0, 4, and 6 days. Mercury metal ions concentration were analyzed using AAS, Shimadzu AA-6300. The results showed that activation using 4 M HCl can open the pores of the biosorbent. Compared to the inactivated biosorbent, the characteristics of this activated biosorbent were better with lower water content (2%), higher ash content (9.9%), greater iodine absorption (1259.14 mg/g), and higher carbon content (89%). Based on SNI.06-3730-1995 Standard, the resulting biosorbent was close to qualified as activated carbon. The highest absorption efficiency of ion Hg(II) was 99.6% which was achieved for 6 days with a 4 grams of biosorbent. The results of this study concluded that the leaves of (Sansivieria sp.) activated by 4M HCl could absorb metal ions Hg(II) well.

Abstract

Wastewater from the outlet of hospital's Wastewater Treatment Plant (WWTP) is expected to be used for watering plants as an effort to water use efficiently. To answer this assumption, this research was carried out to examine the effects of hospital wastewater as a plant growth medium on the accumulation of pollutants in papaya (Carica papaya) leaves and fruit. Local papaya seeds were grown on the land around the hospital's WWTP and the plants were watered every day with wastewater. Plants were well cared for without adding other additives as fertilizer and their growth was observed. After 8 months of treatment, the fruits and leaves of plants were harvested and destructed using HNO3 and H2SO4 to measure the heavy metal content using the Atomic Absorption Spectrophotometer, Shimadzu A630. Results showed that when wastewater was used as a growth medium, metals Hg, Cd, and Pb were found to accumulate in papaya fruit with a concentration of 0.179; 0.582; and 2,327 mg/kg, while other metals such as Cr and As were not found to accumulate in papaya fruit. Metal accumulation was also found in papaya leaves with Hg content of 0.739 mg/kg and Cd of 0.582 mg/kg, while others metals Cr, Pb, and As were not found in the papaya leaves. These results indicate that the main source of heavy metal accumulation in papaya plants came from wastewater from the WWTP outlet containing heavy metals.
