Abstract

Phytoremediation is known as one of the bioremediation techniques which may remove, stabilize, and/or destroy contaminants in the media. This study was aiming at collecting evidence of phytoremediation, which was applied with the addition of compost. Jarak Kepyar (Ricinus communis L.) was selected for this study because its seeds highly potency as biodiesel raw materials. Laboratory research scale was prepared, and the experiment design was complete random design with three replications. The experiment design was a full random design with three replications. The treatments were mixed contaminated soil (contaminated soil: compost = 3:1) and R. communis; and mixed garden soil (soil:compost=3:1) and R. communis; and contaminated soil without compost and R. communis. The statistical t-Test with a range of confidence at 95% showed that the phytoremediation significantly removed the Total Petroleum Hydrocarbons (TPH) at 97.7%. TPH accumulations were detected in roots and shoot ranged from 3377.6 mg/kg to 3555.0 mg/kg. R. communis leave development was the most sensitive indicator to biotoxicity of the hydrocarbons in the soils.

Abstract

Keberadaan tanah pasir pantai menyebabkan proses evaporasi dan degradasi oleh mikroba berlangsung cepat dan tanah pasir pantai miskin unsur hara. Lahan pasir pantai menjadi alternatif lahan pertanian, Penelitian bertujuan untuk mengetahui pengaruh bahan organik dan inokulasi Jamur Mikoriza Arbuskula (JMA) terhadap harkat tanah pasir pantai. Penelitian menggunakan rancangan acak kelompok lengkap dengan 3 ulangan. Faktor diuji adalah takaran bahan organic dari 0, 20, 40, dan 60 ton/ha; dan inokulasi JMA yaitu 0 dan 150 g/lubang tanam. Parameter yang dianalisis adalah pH (H2O), C organik, N total, C/N, P dan K tersedia. Data hasil penelitian dianalisis secara diskriptif dengan membandingkan Harkat sifat kimia tanah yang dikeluarkan oleh Balai Penelitian Tanah (2009), dan dianalisis menggunakan Anova α 1 dan 5%. Bila ada pengaruh yang nyata, dilanjutkan uji BNT α 5%. Penambahan bahan organik ke dalam tanah mampu meningkatkan harkat sifat kimia tanah setelah masa inkubasi. Sedangkan harkat sifat kimia tanah setelah masa tanam jagung yang bermikoriza menurunkan dibanding dengan jagung tanpa JMA. Berdasar analisis keragaman, ternyata takaran bahan organik sebanyak 60 ton/ha merupakan perlakuan terbaik untuk meningkatkan kadar C organik, N total, P dan K tersedia serta KTK pada masa inkubasi. Setelah masa tanam jagung, C organik dan N total tertinggi tejadi pada tanah tanpa mikoriza dengan tambahan bahan organik 40 ton/ha, sedang untuk P dan K tersedia serta KTK terbaik pada tanah bermikoriza dengan tambahan bahan organik 40 ton/ha.

Abstract

The effluent of tofu’s anaerobic digester contains organic matter and require further treatment. Constructed wetland (CW) using forage grass plant is one of the alternatives. The study is aimed to observe the effect of CW’s stage variation and planting duration on TSS and COD effluent. Plant growth also observed duringoperation. Two CWs horizontal subsurface tank of dimension 100 cm x 50 cm x 50 cm were arranged in series as stage 1 and 2. Tank was planted with Pennisetum purpureum c.v Mott at spacing of 25 cm, tank without plants as control, and operated at hydraulic loading rate of 0.1 m3/m2.day. Temperature, pH and plant height was measured every 2 days, TSS and COD every 1-2 week. The study showed, there was relatively no temperature difference between control and planted CW. The pH effluent increased with the pH of stage II being higher than stage IThe TSS and COD removal efficiency in planted CW was 61-90 % and 27-85 %, while for control was 8-85 % and 13-79 %, respectively. Plant can grow, indicated by the addition of plant height and plant weight during harvesting. In conclusion, CW stage and planting duration had effect on TSS and COD effluent.
