Teknologi Fitoremediasi Untuk Penanganan Pencemaran Logam Berat Di Lahan Pertanian Di Kecamatan Kebakkramat Kabupaten Karanganyar

Abstract

Research aim of heavy metal pollution handling in agricultural land use fitoremediation technologyis to know the effectivity of hemp and mendong plant used and it’s combination with rhizobacterial isolates Agrobacterium sp I3 or organic materials in order to decrease the levels of heavy metal contamination in the soil such as cromium (Cr), cadmium (Cd) and plumbum (Pb).The research was conducted in Waru Village Kebakkramat Sub-District Karanganyar Regency in 2016. The location is a subdistrict in Karanganuyar Regency whose area has many industries, mainly textile industry.Industrial wastewater in this region is widely used to irrigate rice fields by farmers, so the paddy fields have been polluted by Cr, Cd and Pb.Therefore, it is necessary to decrease the contamination of heavy metals in paddy fields with the selection of environmentally friendly remediation technology, low cost, easy and sustainable.The method of remediation in that category is bioremediation using a plant called phytoremediation.For that required plants that have rapid growth and high metal absorption capability.The character are owned by hemp and mendong plants.Based on previous research obtained Agrobacterium sp I3 rhizobacteria which proved able to increase the uptake of Cromium by hemp plant.The research result showed that hemp and mendong plants can absorb metal either Pb, Cd, or Cr.Based on the amount of metal absorption value in root and plant canopy, hemp plant and mendong shows its ability as hyper akumulator plant (the amount of uptake ≥ 100 ppm).The highest decrease of soil Pb content was 39,406% without treatment of basic fertilizer, with rhizobacterial inoculation Agrobacterium sp I3 and hemp plant.The highest decrease of soil Cd content was 56,604% with treatment with basic fertilizer, with inoculation of rhizobacteria Agrobacterium sp I3 and mendong plant.The highest decrease of Cr content of soil was 42,27% with treatment of basic fertilizer, without inoculation of Agrobacterium sp sp I3 and without hemp and mendong plants.

Potential of Using Fly Ash as an Additional Mixture for Planting Medium

“…Other impacts that can be felt by humans are lung cancer, kidney failure, anemia, skin allergies, asthma, and stomach cancer. [30] Plants that can grow with Cr metal content and can be utilized, namely purun and mendong plants, are hemp plants with a high ability to absorb metals and belong to the hyperaccumulator category [31]. Purun plants (Typha latifolia) and mendong plants (Fymbristylis umbellaris) can be used as materials for crafts such as mats and can be created into other forms in the form of bags.…”

Analisis Kesuburan Tanah di Pertambangan Minyak Tradisional Desa Wonocolo Kecamatan Kedewan, Kabupaten Bojonegoro

“…Fitoremediasi adalah teknik remediasi in situ yang memanfaatkan kemampuan inheren tanaman hidup. Ini juga merupakan teknologi pembersihan ekologis, ditenagai oleh energi matahari dan didasarkan pada gagasan menggunakan alam untuk membersihkan lingkungan [14]. Pencemaran tanah yang disebabkan oleh tumpahan minyak merupakan masalah lingkungan yang tersebar luas yang seringkali membutuhkan remediasi daerah yang terkontaminasi.…”

“…Penyerapan polutan pada tanaman terjadi terutama melalui sistem akar, yang merupakan mekanisme utama pencegahan toksisitas. Sistem perakaran memberikan luas permukaan yang sangat luas yang menyerap dan mengakumulasi air dan nutrisi yang diperlukan untuk pertumbuhan, serta polutan non-esensial lainnya [14]. Pada ulasan ini, tiga mekanisme diidentifikasi dimana tanaman dapat menangani polutan besar di tanah, sedimen dan air.…”

“…Efforts to guarantee the availability of sufficient and safe food for the community through the intensification of plant cultivation have caused negative impacts. Therefore, it is necessary to ensure food quality and safety by preventing food from possible chemical contamination, especially agrochemicals (Rahman et al 2020;Rosariastuti et al 2020;Sukarjo et al 2021). The use of fertilizers and other agrochemicals is crucial for improving rice production (Liao et al 2021); these two agro-inputs also play a role in the higher levels of heavy metals, particularly cadmium (Cd) (Rahman et al 2020;Rosariastuti et al 2020;Sukarjo et al 2021).…”
