Abstract

Pertambangan emas yang menggunakan metode arsenik dan merkuri dalam proses pemurnian akan selalu menimbulkan dampak lingkungan. Sisa tanah hasil penambangan (tailing) akan dibuang atau didepositkan, dan akan menimbulkan masalah lingkungan dan juga mencemari pangan. Tanaman yang ditumbuhkan pada lahan terkontaminasi dapat bersifat adaptif terhadap kontaminan tetapi tidak mentranslokasikan, ataupun bersifat adaptif dan mentranslokasikan dengan dan tanpa translokasi kontaminan. Penelitian ini bertujuan untuk menguji sifat adaptif/toleran Sawi dan Tomat jika ditanam pada tanah tercemar merkuri dan juga kemampuan translokasi merkuri. Total 6 perlakuan dengan 3 kali pengulangan ditentukan untuk setiap jenis tanaman supaya dapat menarik kesimpulan penelitian, seperti perlakuan tanah tailing saja, tanah tailing campur pupuk (100 mg N, 50 mg P, dan 50 mg K),  tanah tailing dengan kotoran ayam, tanah tailing dengan campuran rumput laut, tanah tailing dengan dosis pupuk rendah (50 mg N, 25 mg P dan 25 mg K), dan tanah non tailing yang dicampur pupuk N,P,K dosis rendah. Untuk sawi dan tomat digunakan masing-masing 18 unit percobaan untuk tomat.  Dosis rumput laut maupun kotoran ayam adalah 5g kering angin kg-1 tanah. Statistik mengunakan analisa Anova 1 arah dengan uji lanjut BNJ. Sawi yang tumbuh pada tanah tailing terkontaminasi 85.700 ηg g-1 mentranslokasikan Hg hingga 17.477 ηg g-1 dan hanya 6.281 ηg g-1 pada tomat.  Efisiensi Sawi sangat tinggi untuk membersihkan kontaminan Hg, minimal 68 kali lebih efisien dari tomat. Pemberian N, P, K pada tanah tailing berkontribusi negatif pada pertumbuhan tanaman berbeda dengan pemberian bahan organik asal kotoran ayam yang memberikan kontribusi positif pada pertumbuhan sawi maupun tomat, juga menurunkan  penyerapan Hg.

Abstract

The need for soybean increasing every year causes soybean imports to be done continually, so an effort to increase the production must be done to reduce dependency on imported soybean. This study aims to determine the characters that can be used as an indicator of selection to increase soybean yields. The study was conducted in the village of Saatu, Coastal Poso Subdistrict, Poso Regency, Central Celebes Province, from January to April 2011. Using a randomized block design (RBD) with 30 genotypes (varieties) as the treatments that were repeated 3 times, so it obtained 90 units of experimental plots. The observed variables were plant height at harvesting time, flowering age, harvesting age, number of pods per plant, number of seeds per pod, number of productive branches per plant, total weight of pods per plot, weight of 100 seeds and yield of seeds. The results showed that plant height at harvesting time, harvesting age and number of seeds per pod have genetic variability coefficients that were moderate while the other traits were high. The number of pods per clump and the number of seeds per pod have moderate heritability values while the other traits were high enough. Harvesting age has a significant negative genetic correlation with the yield while the number of productive branches, total weight of pods per plot and weight of 100 seeds have significant positive genetic correlations with soybean yields. Weight of pods per plot is a trait that has high direct effect on and significant positive correlation with the yields so it can be used as an indicator of trait selection to improve soybean yields.
