Abstract

Leachate atau lindi sampah berpotensi untuk mencemari air pemukaan dan air tanah. Hal ini diakibatkan degradasi biologis leachate menghasilkan pencemar berbahaya seperti zat organik dan logam berat. Penelitian ini bertujuan untuk mengamati efisiensi MSL dalam mereduksi pencemar yang terkandung dalam leachate. Pengamatan penelitian difokuskan pada pengaruh hydraulic loading rate (HLR) terhadap efisiensi reduksi pencemar, yang terdiri atas 250 l/m2.hari, 500 l/m2.hari dan 1000 l/m2.hari. Penelitian ini dilakukan dengan cara mengalirkan secara gravitasi leachate Tempat Pemprosesan Akhir (TPA) Talang Gulo ke reaktor MSL berdimensi 15x50x50 cm. Reaktor MSL terdiri atas lapisan impermeable dan lapisan permeabel. Lapisan impermeabel merupakan lapisan yang terdiri atas campuran tanah dan arang dengan rasio 2 : 1, serta lapisan permeabel terdiri atas lapisan zeolit berdiameter 0,25 – 0,5 cm. Berdasarkan hasil penelitian, didapat bahwa MSL dapat menetralkan pH dan mereduksi konsentrasi pencemar COD, amoniak, besi (Fe) dan warna. Efisiensi reduksi untuk semua pencemar berkisar 92% – 99,966%. Secara umum, HLR sangat mempengaruhi efisiensi reduksi, dimana makin rendah HLR maka makin rendah konsentrasi outlet serta makin tinggi efisiensi reduksi.

Abstract

Coconut wastewater is the by-product of the coconut milk store. It contains BOD of 9.908,41 mg/L and COD of 38.264,73 mg/L. It can pollute when it is discharged into received water directly. Pollution can prevented by wastewater treatment using phytoremediation method and wastewater reuse for hydroponic crops. This study aimed to determine the effectiveness of the hydroponic system in reducing BOD and COD concentration of coconut wastewater, the effect of the reuse coconut wastewater on crop growth, and to analyze the suitability of coconut wastewater with hydroponic’s standard nutrients. The crop selected in this study was Kangkong (Ipomoea reptans Poir) with a vertical hydroponic system. The retention time was determined based on the Day After Planting (DAP). The DAP ranged in 0 day, 7 days, and 14 days. The crop parameters observed in this study are height, the number of leaves, and gross weight, compared to the controlled crops that use hydroponic’s standard nutrients. The highest reduction of BOD (79,22%) and COD (82,76%) occurs on DAP of 7 days. Crop growth increased as BOD and COD decreased. Initial pollution concentration caused stunted growth, so that the measurement results of phytoremediation crops were below the controlled crops. Coconut wastewater is within the range of standard hydroponic nutrients with 6,16-7,62 pH value, 1.220-1.570 ppm TDS, 2.470-3.180 μS/cm EC, and 25-26oC temperature

Abstract

Soil washing is one of the effective methods to remove contaminants in polluted soil by moving them from the solid phase (soil) to the liquid phase (water). This study examines the effect of soil washing on the concentration of Total Petroleum Hydrocarbon (TPH) in petroleum-polluted soil at the Ex-Mining Area in Jambi and the removal of oil and grease in soil washing residue using a fixed bed column. The soil washing method uses a leaching column with various concentrations of Tween 80 surfactant solution of 0.5% (v/v) and 1% (v/v). In addition, leaching was repeated 0, 1, and 2 times. Coffee husk biochar was used as a medium in a fixed bed column to remove oil and grease from soil-washing residue with thickness variations of 10 cm, 20 cm, and 30 cm. The results showed that the soil was loamy sand with an initial TPH content of 3092.75 mg/kg. The soil-washing process reduced the TPH concentration with a removal efficiency of 72.45-90.40%. The highest TPH removal occurred in one leaching repetition at a 0.5% surfactant concentration. The optimum oil and fat removal from the use of a fixed bed column is at 30 cm thickness which is 94.35%.

Abstract

The use of two different crumb rubber adsorbent (CRS), pure crumb rubber sludge (pCRS) and modified crumb rubber sludge (mPCRS) with HNO3 activator was investigated for the removal of Hg(II) from aqueous solution. Batch experiment was conducted to analyze the effect of adsorbent dosage and contact time on the adsorption capacities of pCRS and mCRS. Adsorption isotherm and adsorption kinetics was also analyzed to get description of the adsorption mechanism and the adsorbent properties. The Langmuir isotherm provided the best correlation with the maximum adsorption capacity was 16.00 mg/g an, 17.513 mg/g for respected to pCRS and mCRS. The kinetics studies showed that the Hg(II) for both adsorbents adsorbed rapidly which can be adjusted to the pseudo second order model. Our current study confirmed that CRS was effective adsorbent for the removal of Hg(II) from aqueous solution which followed monolayer and multilayer chemisorption

Abstract

Pengolahan air limbah industri crumb rubber dengan sistem lumpur aktif menghasilkan limbah berupa lumpur padat (Crumb Rubber Sludge) yang membutuhkan penanganan. Industri crumb rubber juga menghasilkan limbah padat lainnya berupa tatal karet yang tidak diolah kembali. Pada proses pengolahannya, selain industri crumb rubber yang menghasilkan limbah padat, terdapat industri kelapa sawit yang juga menghasilkan limbah padat berupa abu sawit. Salah satu cara untuk mengatasi dampak yang ditimbulkan oleh limbah padat indutri adalah dengan memanfaatkan limbah tersebut sebagai adsorben. Adsorben adalah suatu padatan yang memiliki fungsi untuk menyerap suatu komponen tertentu dari suatu larutan. Air limbah industri crumb rubber merupakan salah satu penyebab terjadinya pencemaran lingkungan. Paramater kunci air limbah industri crumb rubber salah satunya BOD (Biological Oxygen Demand), COD (Chemical Oxygen Demand) dan TSS (Total Suspended Solid). Apabila parameter tersebut nilainya melebihi baku mutu dan tidak dilakukan pengolahan, berpotensi menyebabkan pencemaran khususnya sungai sebagai badan air penerima. Hasil penelitian menunjukkan bahwa adsorben modifikasi Crumb Rubber Sludge dan tatal karet (CT) dapat dijadikan adsorben dengan daya serap yang tinggi, sehingga nilai persentase penyisihan berada diatas 80% dengan menggunakan variasi massa 0.5 gr, 1gr, dan 1,5 gr dengan waktu kontak 90 menit pada kecepatan pengadukan 120 rpm.

Abstract

Domestic wastewater is wastewater that comes from the activities of human daily life related to water use. If the wastewater can polute the receiving water such as river, if it is not treated before being discharged. This study aimed to determine the effectiveness and effect of the retention time of the garden with the concept of constructed wetland on the reduction of BOD and COD in domestic wastewater in terms of removal efficiency. The plants selected in this study were Kana plants and Kayu Apu plants, with a continuous circulation system. The variable retention time of wastewater in a garden reactor are 1, 2, 3, 4, 5, 6 and 7 days. The decrease in COD and BOD concentrations was analyzed by comparing COD and BOD before and after the study, as well as the effect of retention time on the effectiveness of COD and BOD reduction in gardens. The residence time did not significantly affect the decrease in the concentration of COD and BOD parameters, where as the highest percentage of COD and BOD reduction efficiency occurred on day 1 of 86% for COD and 84% for BOD.

Abstract

Penelitian dilakukan untuk mengamati penyisihan besi (II) dari larutan cair dengan teknik adsorpsi - batch menggunakan dua varian adsorben sekam padi (sekam padi murni - RRH) dan sekam padi teraktivasi natrium (ARH). Hasil penelitian menunjukkan bahwa kedua adsorben mampu digunakan sebagai adsorben untuk mereduksi besi (II) dari larutan berair. Pada penelitian ini, pengaruh 4 variabel bebas pada dua level rendah dan tinggi meliputi pH (5 dan 9), dosis adsorben (20 dan 80 gr/100 mL), waktu kontak (60 dan 240 menit) dan konsentrasi awal larutan uji (20 dan 60 mg/l) terhadap respon (persentase penghapusan besi (II) menggunakan RRH dan ARH) dirancang dan dianalisis secara statistik menggunakan response surface methodology. Signifikansi faktor-faktor independen dan interaksinya diuji dengan menggunakan analisis varians (ANOVA) dengan batas kepercayaan 95%; (α = 0,05). Nilai optimum dari variabel terpilih diperoleh dengan mensubstitusi model regresi polinomial yang sesuai dan dengan menganalisis plot kontur permukaan respons serta dengan menyelidiki plot efek utama dari empat faktor. Proses adsorpsi sangat bergantung pada pH. Persentase hingga 100% dicapai pada pH 7 untuk kedua adsorben.
