Indonesian Abstract

Logam kromium (Cr) banyak ditemukan pada perairan yang menghasilkan air limbah industri batik, apabila air limbah langsung dibuang ke badan air tanpa diolah akan menimbulkan dampak negatif bagi kehidupan flora dan fauna. Fitoremediasi merupakan salah satu upaya penanganan lahan tercemar logam berat Cr dengan menggunakan tanaman. Beberapa tanaman air yang seringkali menjadi gulma dapat dimanfaatkan dalam remediasi pencemaran logam berat dalam lingkungan perairan diantaranya Sagittaria lancifolia dan Pistia stratiotes. Tujuan penelitian ini untuk mempelajari potensi tanaman air Sagittaria lancifolia dan Pistia stratiotes dalam fitoremediasi air tercemar logam Cr dan pengaruh air pascafitoremediasi terhadap pertumbuhan dan hasil tanaman kangkung darat dimana hasil tersebut aman dikonsumsi atau tidak dengan melihat kadar Cr yang terkandung dalam tanaman. Penelitian dilakukan di Greenhouse BKT Kebun Raya Purwodadi-LIPI, menggunakan metode penelitian Rancangan Acak Lengkap (RAL) dengan 6 kombinasi perlakuan yaitu PSM1 (PS + 2 ppm Cr); PSM2 (PS + 5 ppm Cr); SLM1 (SL + 2 ppm Cr); SLM2 (SL + 5 ppm Cr); TTM1 (TT + 2 ppm Cr) dan TTM2 (TT + 5 ppm Cr) dimana PS (Pistia stratiotes), SL (Sagittaria lancifolia) dan TT (Tanpa Tanaman/Kontrol) masing-masing perlakuan diulang sebanyak 3 kali. Parameter yang diamati adalah warna daun, tinggi tanaman, jumlah daun, pH air dan tanah, kandungan Cr dalam air dan tanah, konsentrasi Cr pada tajuk dan akar tanaman Sagittaria lancifolia dan Pistia stratiotes serta kangkung darat. Pengamatan warna daun dilakukan pada tanaman air pada 2, 4, 6, 8, 10, 12 dan 14 Hari Setelah Perlakuan (HSP). Pengamatan tinggi tanaman dan jumlah daun dilakukan pada kangkung darat 7, 14, 21 dan 28 hari setelah tanam (HST). Sedangkan parameter lainnya diamati waktu panen yaitu 28 HST. Data dianalisis ragam pada taraf 5% dan perbedaan nyata antar perlakuan dilanjutkan dengan uji BNJ taraf 5%. Hasil penelitian menunjukkan bahwa tanaman air Sagittaria lancifolia dan Pistia stratiotes berpotensi sebagai fitoremediator dan mampu menurunkan kadar Cr dalam air tercemar masing-masing perlakuan PSM1 sebesar 1,757 ppm atau 87,85%; PSM2 sebesar 4,379 ppm atau 87,59%; SLM1 sebesar 1,785 ppm atau 89,23% dan SLM2 sebesar 4,032 ppm atau 80,64%. Konsentrasi Cr pada air pascafitoremediasi berpengaruh nyata terhadap kadar Cr yang terkandung dalam tanaman kangkung darat. Perlakuan SLM1 memiliki nilai konsentrasi Cr tertinggi pada tajuk tanaman kangkung darat sebesar 0,184 ppm dan perlakuan TTM1 memiliki nilai konsentrasi Cr terendah yaitu 0,098 ppm. Hasil tersebut menunjukkan bahwa tanaman kangkung darat tidak aman untuk dikonsumsi karena kadar Cr dalam tanaman telah melewati ambang batas kadar Cr dalam makanan yaitu sebesar 0,05-0,2 ppm per hari.

English Abstract

Chromium (Cr) is commonly found in water containing waste of batik industry. Direct disposal of waste to water body without any treatment will cause adverse effects on the lives of plants and animals. Phytoremediation is one of the efforts to treat Cr contaminated land using plants. Several aquatic plants that usually become weeds can be utilized in the remediation of heavy metal contamination in aquatic environment, including Sagittaria lancifolia and Pistia stratiotes. The objective of this research was to study the potential of aquatic plants Sagittaria lancifolia and Pistia stratiotes in the phytoremedition of Chromium contaminated water and the impact of water after phytoremedition on the growth and production of Kangkong crop as to whether it is safe for consumption or not by checking the levels of Chromium contained in it. The research was conducted at the Greenhouse of BKT Kebun Raya Purwodadi-LIPI using Completely Randomized Design (CRD) with six combinations of treatments, namely PSM1 (PS + 2 ppm Cr); PSM2 (PS + 5 ppm Cr); SLM1 (SL + 2 ppm Cr); SLM2 (SL + 5 ppm Cr); TTM1 (TT + 2 ppm Cr) and TTM2 (TT + 5 ppm Cr), where PS (Pistia stratiotes), SL (Sagittaria lancifolia) and TT (Without Plant/Control), and each treatment was repeated three times. The parameters observed were leaf color, plant height, number of leaves, water and soil pH, Cr levels in water and land, Cr absorption in the canopy’s and roots of Sagittaria lancifolia and Pistia stratiotes as well as Kangkong. The observation of leaf color was carried out on aquatic plants on 2, 4, 6, 8, 10, 12 and 14 days after treatment. The observation of plant height and number of leaves of Kangkong were conducted on 7, 14, 21 and 28 days after planting. Meanwhile, the other parameters were observed on the harvest period, namely 28 days after planting. Data were analyzed by F test level of 5% and a significant difference between treatments, followed by BNJ test at a level of 5% for the treatments. The results of the research showed that the aquatic plants Sagittaria lancifolia and Pistia stratiotes had a potential to be used as phytomediators and were able to reduce the Cr levels in contaminated water in treatments of PSM1 by 1,757 ppm or 87,85%; PSM2 by 4,379 ppm or 87,59%; SLM1 by 1,785 ppm or 89,23% and SLM2 by 4,032 ppm or 80,64%. The concentration of Cr on the water after phytoremediation had a significant impact on the Cr levels contained in canopy kangkong. The treatment of SLM1 had the highest Cr absorption of 0,184 ppm compared to TTM1 treatment with the lowest Cr absorption of 0,098 ppm. Kangkong is not safe for consumption as the Cr levels in the plant are greater than the Cr levels in food, namely 0,05-0,2 ppm per day.
