Abstract
Abstrak Lumpur Lapindo (LL) mengandung berbagai logam berat, termasuk tembaga (Cu), dengan kadar yang melebihi ambang batas baku mutu lingkungan sehingga berpotensi mencemari tanah dan ekosistem sekitarnya. Salah satu metode yang dapat diterapkan untuk mengurangi pencemaran tersebut adalah fitoremediasi menggunakan tanaman hiperakumulator. Penelitian ini bertujuan untuk (1) mengetahui pengaruh pencampuran lumpur Lapindo dengan tanah terhadap kadar Cu dalam media tanam, serta (2) menentukan komposisi media tanam yang optimal bagi serapan Cu oleh kangkung darat (Ipomoea reptans Poir). Penelitian dilakukan dengan metode eksperimen menggunakan empat perlakuan komposisi media tanam: 100% lumpur, tanah:lumpur = 1:1, tanah:lumpur = (1:), dan tanah:lumpur = 1:), masing-masing dengan berat 600 gram per polybag. Tanaman dipanen pada 10 dan 20 hari setelah tanam, kemudian dianalisis kadar Cu dalam tanah dan tanaman, bioakumulasi, serta parameter pertumbuhan seperti tinggi tanaman dan berat kering. Data dianalisis menggunakan ANOVA taraf 5% dan uji Beda Nyata Terkecil (BNT). Hasil penelitian menunjukkan bahwa pencampuran lumpur Lapindo dengan tanah menurunkan kadar Cu dalam media tanam, dengan kadar Cu terendah pada K1 (25 ppm) dan tertinggi pada K3 (29 ppm). Perlakuan K1 (1:1) menghasilkan serapan Cu tertinggi (10,17 ppm) dan indeks bioakumulasi sebesar 0,40, sehingga menjadi komposisi paling optimal untuk fitoremediasi Cu. Temuan ini menunjukkan potensi kangkung darat sebagai agen fitoremediator untuk mengurangi pencemaran Cu pada tanah tercemar lumpur Lapindo. Kata kunci: indeks bioakumulasi, serapan cu tanaman, kadar cu tanah, biomassa tanaman, pertumbuhan tanaman Abstract Lapindo mud contains various heavy metals, including copper (Cu), at levels exceeding environmental quality standards, posing a risk of soil and ecosystem contamination. Phytoremediation using hyperaccumulator plants offers an environmentally friendly and cost-effective approach to mitigating such pollution. This study aimed to (1) evaluate the effect of mixing Lapindo mud with soil on Cu concentration in the growing media, and (2) determine the optimal media composition for Cu uptake by water spinach (Ipomoea reptans Poir). The experiment used four treatments: 100% mu), soil:mud = 1:1, soil:mud = 1:2, and soil:mud = 1:3, each with 600 g per polybag. Plants were harvested at 10 and 20 days after planting, and measurements included Cu concentration in soil and plants, bioaccumulation index, and growth parameters such as plant height and dry weight. Data were analyzed using ANOVA at a 5% significance level, followed by the Least Significant Difference (LSD) test. Results showed that mixing Lapindo mud with soil reduced Cu concentration in the growing media, with the lowest Cu concentration observed in K1 (25 ppm) and the highest in K3 (29 ppm). The K1 (1:1) treatment achieved the highest Cu uptake (10.17 ppm) and bioaccumulation index (0.40), making it the most effective composition for Cu phytoremediation. These findings highlight the potential of water spinach as a phytoremediator to reduce Cu contamination in Lapindo mud-polluted soils. Keywords: bioaccumulation index, plant cu uptake, soil cu concentration, plant biomass, plant growth
