“…The growth of microorganisms that carry out chromium biosorption and biogas production is influenced by temperature, acidity (pH), and the number of nutrients. The biosorption of heavy metals by bacteria can be more effective at a certain pH, depending on the type of bacteria (Fatmawati, 2013). In general, the pH and temperature of the biodigester shown in Table 5 and Fig.…”

Water hyacinth (Eichhornia crassipes) is a plant species commonly used for phytoremediation to reduce high chromium content in tannery liquid waste in Garut, West Java. Water hyacinth materials harvested from the phytoremediation can be used for the anaerobic digestion process to produce biogas and bio-slurry. This study aimed to determine the reduction of chromium content found in water hyacinths due to the anaerobic digestion process, and utilization of bio-slurry from the anaerobic digestion process as a biocomposite material. The anaerobic digestion process was carried out for 33 d using biodigesters and the composition of the biodigesters were varied into 100% dried water hyacinths and 80% water hyacinths with the addition of 20% cow dung. The bio-slurry from the anaerobic digestion process was then used for making biocomposites with 3 different compositions, i.e., 75 and 25%; 50 and 50%; and 25 and 75% of cement and bio-slurry, respectively. The average chromium content found in water hyacinths from the phytoremediation process without anaerobic digestion process was 41.964 mg/l. The results show a reduction in the amount of chromium after the anaerobic digestion process was found in each composition of bio-slurry, which were 15.979 mg/l (100% water hyacinth) and 14.861 mg/l (80% water hyacinth + 20% cow dung). Biodigester with a composition of 80% water hyacinth + 20% cow dung produced the highest average volume of biogas which was 0.424 l. The biocomposite of 75% cement and 25% bio-slurry had the highest compressive strength value of 30.598 MPa and water absorption capacity of 37.25%. It can be concluded that biocomposite with the composition of 75% cement and 25% water hyacinth bio-slurry is promising to be used as an alternative material for buildings.

“…Fitoakumulasi adalah proses penyerapan polutan logam, termasuk logam radioaktif seperti torium, oleh akar tumbuhan dan mengakumulasikannya ke bagian tumbuhan, seperti akar, batang, atau daun. Proses fitoakumulasi juga telah dilaporkan dapat menyebabkan dekontaminasi logam dengan baik pada unsur seperti Sr-90, Cs-137, Pu-239, U-238, dan U-234 [37].…”

ABSTRAK Limbah torium (Th) merupakan limbah radioaktif pemancar alfa yang berbahaya bagi lingkungan dan makhluk hidup sehingga perlu dilakukan pengolahan limbah yang efektif dengan fitoremediasi. Fitoremediasi adalah kemampuan tumbuhan untuk mengurangi bahan pencemar yang ada dalam lingkungan. Tujuan penelitian adalah menguji kemampuan tumbuhan kayu apu dalam menurunkan kadar Th dari limbah yang terkontaminasi Th. Kadar Th pada tumbuhan kayu apu dan limbah cair dianalisis dengan Spektrofotometer UV-VIS sementara radioaktivitasnya diukur dengan Ludlum Model 1000 Scaler. Parameter terjadinya fitoremediasi antara lain kondisi fisik tumbuhan yang menurun, pH limbah yang mendekati netral, dan suhu yang fluktuatif mengikuti suhu lingkungan. Hasil penelitian menunjukkan biomassa tumbuhan kayu apu mengalami penurunan setelah fitoremediasi menjadi 96,2% dengan efisiensi remediasi sebesar 97,4% dari konsentrasi awal limbah radioaktif cair Th sebesar 10 ppm. Hal ini disebabkan karena terjadinya penyerapan Th sehingga mengakibatkan akumulasi Th pada tumbuhan kayu apu sebesar 4069,4 mg/kg. Tumbuhan kayu apu juga mampu menurunkan radioaktivitas limbah cair Th menjadi 0,631 Bq/L dari radioaktivitas awal sebesar 2,819 Bq/L. Tingkat radioaktivitas sudah di bawah Tingkat Klierens dan limbah dapat dilepas ke lingkungan dengan aman.ABSTRACT Thorium (Th) waste is an alpha-emitting radioactive waste that is harmful to the environment and living things so it is necessary to treat the waste effectively with phytoremediation. Phytoremediation is a plant ability to reduce pollutants presence in the environment. This research aim is examining apu wood plant ability to reduce Th contents from Th-contaminated waste. The UV-VIS spectrophotometer analysed Th level in apu wood plant and liquid waste while the Ludlum Model 1000 Scaler measured their radioactivity. The parameters for phytoremediation occurrence include the decreasing physical condition of the plants, the pH of the waste that is close to neutral, and the temperature that fluctuates with the ambient temperature. The results showed that the plant biomass of apu wood decreased after phytoremediation to 96.2% with a remediation efficiency of 97.4% from the initial concentration of Th liquid radioactive waste of 10 ppm. This is due to thorium absorption resulting in thorium accumulation in apu wood plants of 4,069.4 mg/kg. Apu wood was also able to reduce Th liquid waste radioactivity to 0.631 Bq/L from the initial radioactivity of 2.819 Bq/L. The radioactivity level is below the Klierens Level and it is safe to release the waste into the environment.

Lapindo Mudflow in Sidoarjo in 2006 brought heavy metals cadmium (Cd) that polluted the soil and environment around the affected area. Phytoremediation using water spinach (Ipomea reptans) is one of the alternatives to decrease the heavy metal pollution on Lapindo mud. The organic materials (compost and biochar) can also be used to reduce the contamination of heavy metals in soils. The aim of this study was to obtain the best composition of organic matter and biochar to support phytoremediation using water spinach plant in the cadmium-polluted soil. The study was conducted in a greenhouse with eight treatments consisted of four levels of organic matter application. The parameters measured were plant height, number of leaves, pH, CD content, and uptake of Cd. The results showed that there was a significant effect on the addition of compost and biochar on plant growth, Cd content, and Cd uptake. Results of the study showed that the addition of compost gave better results than that of biochar. The best treatment was on K7 (contaminated soil : compost : biochar; 1:1:1) for all parameters observed. Compared to the K0 (control) treatment, height of the plant increased up to 24%, the number of leaves increased up to 100%, the Cd content in the roots and shoots increased up to 44% and 95%, the content of the Cd in the planting media after the planting period decreased by 61%.
