Abstract

Penggunaan insektisida oleh petani untuk memberantas hama pada tanaman umumnya
hanya mengira-ngira tanpa menggunakan dosis rekomendasi, sehingga dapat
menyebabkan pencemaran lingkungan. Beberapa organisme dapat dijadikan sebagai
indikator tercemarnya suatu lingkungan. Diantara organisme tersebut adalah cacing
tanah. Penelitian bertujuan untuk mengetahui pengaruh insektisida terhadap mortalitas,
bobot tubuh dan aktivitas cacing Lumbricus rubellus pada proses dekomposisi bahan
organik (C/N rasio) di tanah sawah. Penelitian menggunakan Rancangan Acak
Lengkap (RAL) pola split plot dengan 3 kali ulangan. Sebagai main plot adalah
Karbofuran 3% dari insektisida Furadan 3GR yang terdiri dari 5 dosis 0, 25, 50, 75,
100 mg/kg (berat kering tanah) dan sebagai sub plot yaitu bahan organik yaitu kotoran
sapi dan sampah pasar. Parameter yang diamati sebelum perlakuan yaitu tingkat
mortalitas dan bobot tubuh cacing Lumbricus rubellus, C-organik, N-total, C/N rasio,
BV, BJ, dan porositas tanah. Parameter yang diamati setelah perlakuan yaitu tingkat
mortalitas dan bobot tubuh cacing (kematian) cacing Lumbricus rubellus, C-organik,
N-total, C/N rasio, pH, suhu, BV, BJ, dan porositas tanah. Analisis data menggunakan
sidik ragam (ANOVA) dan diikuti dengan uji lanjutan menggunakan Duncan Multiple
Range Test (DMRT) pada taraf uji 5%. Hasil penelitian menunjukan bahwa pemberian
Karbofuran berpengaruh nyata terhadap mortalitas, bobot tubuh cacing Lumbricus
rubellus, pH, suhu, tetapi tidak berpengaruh nyata terhadap C-organik, N-total, BV,
BJ, porositas. Penambahan bahan organik berpengaruh nyata terhadap mortalitas,
bobot tubuh cacing Lumbricus rubellus, C-organik, N-total, tetapi tidak berpengaruh
nyata terhadap BV, BJ, porositas, pH, dan suhu. Pemberian Karbofuran 100 mg/kg
berat tanah menyebabkan mortalitas cacing tertinggi dan penurunan bobot tubuh cacing
tertinggi. Penambahan bahan organik sampah pasar menghasilkan hasil yang lebih baik
dari pada penambahanan bahan organik kotoran sapi.

ABSTRACT
The use of insecticides by farmers to eradicate pests in plants generally only estimates
without using dose recommendations, so that it can cause environmental pollution.
Some organisms can be used as an indicator of the pollution of an environment. Among
these organisms are earthworms. This research was aimed to know the effect of
insecticides on disabled mortality, body weight and activities Lumbricus rubellus in
decomposition process of organic materials (C/N ratio) in land soil. Research method
that was used in this research was Complete Randomized Design split plot pattern with
3 replications. As the main plot is 3% Carbofuran from Furadan insecticide 3GR which
consists of 5 doses of 0, 25, 50, 75, 100 mg/kg (dry weight of soil) and as sub-plots of
organic matter of cow faeces and market trash. Parameters that was analyzed before
treatments are total mortality and body weight Lumbricus rubellus, C-organic, N-Total,
C / N ratio, BV, BJ, and soil porosity. Soil analysis after treatment including are total
mortality and body weight Lumbricus rubellus, C-organic, N-Total, C / N ratio, pH,
temperature, BV, BJ, and soil porosity. Analysis data (ANOVA) was used followed by
advanced test using Duncan Multiple Range Test (DMRT) on 5% level. The result of
the research showed that by giving Carbofuran has a significant effect total mortality
and body weight Lumbricus rubellus, pH, temperature, but non-significantly give effect
to C-organic, N-total, BV, BJ, porosity. Addition of organic matter has a significant
effect on total mortality and body weight Lumbricus rubellus, C-organic, N-total, but
non-significantly give effect to BV, BJ, porosity, pH, dan temperature. Giving
Carbofuran 100 mg / kg of soil weight caused the highest worm mortality and decreased
body weight of the highest worms.The addition of organic matter market trash produces
better results in the reform of organic matter compared to cow feces.
Keywords: Carbofuran, Lumbricus rubellus, mortality, body weight, C/N ratio
