Abstract: The using of insecticides will have a negative impact on the biodiversity, environment, food quality and human health. One way is a remediation technology by using activated carbon. Research conducted at the Muara experimental station, Bogor-West Java in 2009 (in paddy field) by RCBD with four activated carbons (AC) treatment: coconut shell, corn cobs, rice husk and palm oil empty fruit bunches (POEFB) were tested. Size of AC used was 50 mesh. Quality ofAC should be refers to the SNI06-3730-1995 (Indonesian Standard).Application of AC was in the days before planting. Application AC like as urea fertilizer (by spread). Dose of AC used was 1000 kg/ha or 1.2 kg/plot. Soil sampling was conducted at 1, 40 and 80 days after treatment (DAT). Theinsecticides (lindane and chlorpyrifos) in soil samples were analysed by gas chromatography (GC). In the soil samples was also observed that the presence of insecticide degrading microbes. Based on the field test results showed that AC of coconut shells, corn cobs, rice husk and POEFB have an effect on decrease of chlorpyrifos and lindane residues. AC could be increaseddegrade by microbial populations such as Citrobacter, Enterobacter, and Azotobacter. Activated carbon as a potential bioremediation in soil because its serve as decomposers insecticide residues (chlorpyrifos and lindane).

Keywords: remediation, insecticide residue, and activated carbon.


Abstrak: Penggunaan insektisida berdampak negatif pada biodiversitas, lingkungan, kualitas pangan, dan kesehatan manusia. Teknologi remdediasi dengan menggunakan arang aktif merupakan salah satu cara penanggulangannya. Penelitian telah dilaksanakan di Kebun Percobaan Muara Bogor, Jawa Barat pada tahun 2009 (padi) dengan rancangan percobaan acak kelompok empat. Perlakuan yang diujikan adalah karbon aktif tempurung kelapa, tongkol jagung, sekam padi, dan tandan kosong kelapa sawit berukuran 50 mesh. Kualitas karbon aktif mengacu SNI06-3730-1995. Aplikasi karbon aktif sehari sebelum tanam sama seperti urea dengan cara ditabur dengan dosis 1000 kg/ha atau 1,2 kg/plot. Pengambilan contoh tanah dilakukan saat 1, 40, dan 80 hari setelah aplikasi (HSA). Residu lindan dan klorpirifos dalam tanah dianalisis menggunakan GC. Selain itu diamati pula keberadaan mikroba yang mendegradasi insektisida. Hasil pengujian lapang menunjukkan bahwa karbon aktif tempurung kelapa, tongkol jagung, sekam padi, dan tandan kosong kelapa sawit berpengaruh menurunkan residu lindan dan klorpirifos. Karbon aktif dapat meningkatkan degradasi insektisida oleh populasi mikroba Citrobacter, Enterobacter, and Azotobacter. Karbon aktif sebagai bioremediasi yang potensial dalam tanah karena membantu decomposer residu insektisida (klorpirifos dan linden).

Kata kunci: remediasi, residu insektisida, dan karbon aktif.
