Abstract

Poor landfill management and not in accordance with the rules raises serious problems of liquid waste (leachate). One alternative treatment of heavy metal contaminated waste is phytoremediation techniques with aquatic plants. The purpose of this study was to determine the effect of growth on Typha Latifolia test plants using leachate concentrations. The study used the concentration method for diluting V1.N1 = V2.N2 and Regression. The leachate concentrations used were 20%, 40%, 60%, 80% and 100% and control. Observation data focused on the number of tillers, root length, leaf length and number of leaf petals. The results obtained from the observation data the higher the leachate concentration, the lower the number of tillers, root length, number of leaves and number of leaf petals in Typha latifolia test plants. This proves that Typha latifolia plants are hyperaccumulator plants that can grow on leachate.

Abstract

Limbah kulit durian yang menumpuk akan menjadi sumber pencemar jika tidak diberdayakan dengan benar. Salah satu upaya untuk memberdayakan limbah kulit durian adalah mengolahnya menjadi produk bioetanol. Kulit durian mengandung 5% elemen zat tepung dan lignin yang mengandung 50-60% selulosa. Selulosa merupakan karbohidrat utama yang disintesis oleh tanaman dan hampir 60% penyusun struktur. Karbohidrat adalah bahan dasar dalam pembuatan etanol. Penelitian ini menggunakan limbah kulit durian untuk produksi bioetanol melalui proses fermentasi dengan penambahan Saccharomyces cerevisiae (ragi). Penggunaan enzim alphaamilase dan enzim glukoamilase untuk pemecahan selulosa dalam limbah kulit durian sehingga produksi bioetanol semakin meningkat. Sampel limbah kulit durian ini menunjukkan hasil dimana pH 4.5  dan suhu 35°C merupakan pH dan suhu fermentasi sampel limbah kulit durian yang memiliki persentase maksimum produksi bioetanol. Hal ini membuktikan bahwa konsentrasi etanol dalam air secara bertahap meningkat seiring dengan meningkatnya pH dan mencapai persentase maksimum produksi bioetanol pada pH 4,5 dan menurun pada pH 5. Melalui penelitian ini diharapkan mampu mengurangi pencemaran lingkungan dari penumpukan limbah kulit durian dan menjadi bahan bakar alternatif baru produksi bioetanol.

Abstract

Increase in science and technology development today has spurred environmental pollution in water, soil and air. Water pollution caused by the impact of industrial development must be controlled as quickly as possible. The study aimed to investigate the effect of Eichhornia crassipes plants at given metal concentrations. The Eichhornia crassipes plant was used as an observation material with varying concentrations of metal (Cr, Hg, and Pb). The method used in this study was Randomised Block Design (RBD) and continued with Duncan's Multiple Range Test analysis, or better known as the DMRT test. The study observations showed that the increase in Eichhornia crassipes seedlings was 3cm, 2cm and 2cm, respectively with the recorded concentrations of 20%, 40%, 60%, and 80%. Meanwhile, the leachate concentrations of 20%, 40%, 60%, and 80% could also increase the roots of Eichhornia crassipes plants by 3.5cm, 1.5cm and 1cm, respectively. However, the leaf growth of Eichhornia crassipes plants at concentrations of 20% and 40% recorded as much as three and two leaves only. Additionally, it can be noted that at leachate concentrations of 20% and 40%, there was an increase in the number of Eichhornia crassipes leaf petals during observation. Overall results showed that low concentrations could increase the Eichhornia crassipes plants. This was evident in the statistical test analysis, where the leachate concentration in the Eichhornia crassipes plant affected the overall test results.
