Abstract

Soil is a very influential medium of human survival. One of the parameters affecting soil quality is heavy metal concentration in soil, especially heavy metal of lead (Pb). High concentrations of Pb in the soil can treated with phytoremediation techniques. The aims of this research are: 1. To investigate the reduction of heavy metal Pb in the soil by phytoremediation, 2. To investigate the effectiveness of plants to absorb heavy metal Pb in the soil, and 3. To investigate the distribution of Pb concentration in the plant parts. The study variables used in this research are species variation of plants Sansevieria trifasciata and Celosia pulmosa. Phytoremediation test of Pb heavy metal contaminated soil was carried out for 4 weeks with sampling time on days 0, 7, 14, 21, and 28. The parameters analyzed of this research is Pb concentrations on soil and plant parts, namely roots, stems, leaf. Physical observations of plants were also carried out to support this research. The results show that the reactor with Sansevieria trifasciata had a higher effectiveness of removal of Pb in 81.08% (112 mg/kg) than Celosia pulmosa in 59.63% (293 mg/kg). The effectiveness of the absorption of Sansevieria trifasciata was higher 70.50% (418 mg/kg) than Celosia pulmosa 52.40% (311 mg/kg). The distribution of Pb concentrations in the plant of Sansevieria trifasciata and Celosia pulmosa is almost the same, with the most concentration being in the root part and at least scattered in the leaves of the plant. Keywords: Celosia pulmosa, Soil, Lead, Phytoremediation, Sanseviera trifasciata.

Abstract

Plastik merupakan suatu material industri dengan banyak kelebihan ekonomis sehingga diproduksi dan digunakan meluas hampir di seluruh aspek kehidupan manusia. Namun, plastik memiliki kekurangan yaitu sulit terurai di lingkungan karena ikatan rantai karbon yang panjang. Akibatnya, diperlukan lebih dari satu dekade agar plastik terdegradasi dan termineralisasi ke lingkungan. Peningkatan jumlah konsumsi plastik tentu menambah dampak akibat sampah plastik yang dibuang ke lingkungan. Biodegradasi adalah salah satu upaya untuk mengelola sampah plastik. Tujuan penelitian ini yaitu untuk menganalisis potensi bakteri yang diisolasi dari sedimen Mangrove Wonorejo Surabaya dalam mendegradasi plastik Polyethylene, Polypropylene, dan Polystyrene menggunakan metode Kolom Winogradsky. Substrat yang digunakan adalah pasir dan tanah, dengan Bushnell-Haas broth sebagai media tumbuh bakteri, dan plastik uji ukuran 10x3 cm. Besar persen degradasi dihitung berdasarkan selisih berat kering sebelum dan sesudah masa inkubasi selama 12 minggu. Sebanyak 17 isolat bakteri berhasil diisolasi dari masing-masing sumber sampel. Persen degradasi terbesar ditemukan pada sampel sedimen mangrove titik 3 substrat pasir sebesar 82.3% pada plastik PP. Sedangkan plastik PS diperoleh persen degradasi sebesar 34.1% pada sedimen mangrove titik 5 substrat tanah.

Abstract

Piles of waste in landfills can produce leachate that smells bad and contains organic and inorganic materials as well as some pathogenic bacteria. A biofilter is a simple method that can be used to degrade pollutant parameters dissolved in leachate. This research aims to determine the efficiency value of Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), and Total Suspended Solid (TSS) concentrations in the leachate of Blandongan Landfill, Pasuruan City. The leachate treatment process uses the coagulation method as pretreatment with aluminum sulfate coagulants (Al2(SO4)3) and Ferric Chloride (FeCl3) followed by biofilter using bioball media. The variables in this research were the differences in the concentration of the coagulant used and the bioball media with a height of 15 cm. The results show that in bioball me-dia the value of reduction efficiency is better in reducing COD levels by 77.73%, BOD by 79.40%, and TSS by 81.48%. This research combines leachate treatment technol-ogy, where the coagulation-flocculation method becomes the pre-treatment of the leachate before continuing with an anaerobic-aerobic biofilter.

Abstract

Limbah cair dari hasil industri adhesive tape mengandung kadar COD, TSS, amonia total, minyak lemak dan pH yang tinggi. Penelitian ini bertujuan untuk mengkaji pengaruh variasi tegangan dan waktu kontak saat proses elektrokoagulasi terhadap penurunan kadar COD, TSS, amonia total, minyak lemak dan pH pada limbah adhesive tape. Pengujian dilakukan menggunakan reaktor berukuran 20 cm x 20 cm x 14 cm. Tegangan yang digunakan adalah 8V, 14V dan 20V, sedangkan waktu kontak terdiri dari 40 menit dan 70 menit. Elektroda yang digunakan adalah plat Seng (Zn) dengan ukuran 10 cm x 4 cm dengan jumlah total 8 plat. Hasil penelitian menunjukkan bahwa tegangan yang paling efektif adalah 20V dengan waktu pengolahan selama 70 menit. Efisiensi penurunan kadar COD sebesar 99,12% TSS sebesar 89,61% amonia total sebesar 93,14% dan minyak lemak sebesar 97,38%.
