Abstract

Abstrak: Salah satu alternatif teknik pengolahan tanah terkontaminasi minyak dengan remediasi secara fisik dan kimia adalah dengan teknik soil washing. Soil washing adalah proses reduksi volume atau miniminasi limbah dimana partikel tanah yang mengandung mayoritas kontaminan dipisahkan dari fraksi bulk tanah, atau kontaminan disisihkan dari tanah dengan larutan kimia dan di-recovery dari larutan dalam bentuk substrat padat. Kajian awal yang dilakukan untuk menerapkan teknik soil washing adalah karakteristik tanah tercemar minyak yaitu analisa Oil and Grease, TPH, GCMS, grain size, dan XRD. Tanah dengan tekstur sand, loam dan sandy loam yang mengandung TPH dengan persentase 2,34%, 1,61% dan 4,48% secara berurutan akan diolah dengan teknik soil washing menggunakan surfaktan Tween 80 dan rasio solid/liquid yang sesuai. Hasil variasi konsentrasi larutan surfaktan menunjukkan bahwa konsentrasi surfaktan optimum dalam penyisihan TPH dari ketiga tekstur tanah adalan 0,25% untuk tanah sand, 1% untuk tanah loam dan 0,5% untuk tanah sandy loam. Sedangkan rasio solid/liquid optimum adalah 1:15 (gr/ml) untuk ketiga tekstur tanah. Penyisihan TPH yang tercapai dengan pengadukan selama 10 jam dari masing-masing tekstur tanah adalah 85,32% pada tanah sand, 47,65% pada tanah loam, dan 72,94% pada tanah sandy loam. Koefisien distribusi (Kd) TPH setelah proses soil washing tanah sand, loam dan sandy loam adalah 0,388 g/ml, 0,071 g/ml, dan 0,180 g/ml. Kata Kunci: soil washing, surfaktan, rasio solid/liquid, tangki berpengaduk Abstract: Among alternative technique for remediation of contaminated soil is chemical and phsycal technique that is soil washing. soil washing is a volume reduction/waste minimization treatment process where those soil particles which "host" the majority of the contamination are separated from the bulk soil fractions, or contaminants are removed from the soil by aqueous chemicals and recovered from solution on a solid substrate. Pre-study for application of soil washing is examination of soil characteristics including Oil and Grease, TPH, GCMS, grain size and XRD analysis. Sand, Loam, and Sandy Loam with TPH consentration of 2.34%, 1.61% and 4.48% respectively will be treated using Tween 80 surfactant enhanced soil washing method and optimum solid/liquid ratio. Variation in surfactant solution resulting the optimum surfactant concentration of 0.25% for sand, 1% for loam, and 0.5% for sandy loam. Meanwhile optimum solid/liquid ratio for the soils are 1:15 (gr/ml). TPH removal achieved after agitation for 10 hours of three types of soil are 85.32% for sand, 47.65% for loam, dan 72.94% for sandy loam. TPH distribution coefficient (Kd) after soil washing of sand, loam and sandy loam were 0,388 g/ml, 0,071 g/ml, and 0,180 g/ml respectively. Keyword: soil washing, surfactant, solid/liquid ratio, agitated vessel

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

The liquid waste produced by the tofu industry is organic waste which is degradable or can be naturally decomposed by microorganisms. This study aims to measure the volume of tofu industrial wastewater required to produce biogas with a certain pressure so that the liquid waste used as raw material can be utilized optimally. In addition, testing the content of TSS, ammonia, BOD5, COD, and pH in tofu waste in the process of processing it into biogas was also carried out. Experiments were carried out using a biodigester to create anaerobic conditions for tofu waste. The presence of the decomposition gas is detected using a simple manometer. In addition, the possibility of methane gas is estimated by conducting a flame test. The variation of the composition of tofu waste and cow dung (starter) with volume ratio in the biodigester is without starter on Gallon I and Drum I, using a 2% starter on Drum II, and using a 10% starter on Gallon II. The experimental results showed that each biodigester drum I, drum II, gallon I and gallon II produced maximum pressures of 2,158.2 Pa, 42,844.9 Pa, 1863.9 Pa, and 3,629.7 Pa. The maximum retention time for each biodigester drum I, drum II, gallon I, and gallon II was 53 days, 43 days, 58 days and 49 days. The flame test conducted showed that there was only a flame in the biodigester with the addition of a starter material of 10%. Processing of tofu waste into biogas without a starter can reduce the pollutant content, namely TSS and ammonia by 96.5% and 96%, whereas with a starter of 2% by 95% and 94%, and with a starter of 10% by 91% and 95%. Likewise with BOD and COD parameters, the reduction in waste without starter was 96% and 97%, with a starter of 2% by 96% and 96%, and with a starter of 10% by 97% and 98%. The increase in pH occurred in waste without starter to 0.99, waste with a starter of 2% was 1.65 and waste with a starter of 10% was 1.27.

Abstract

The increasing of palm oil mills as a result of an increase in public interest of land exploitation to produce  palm oil can cause high environmental pollution if the waste oil generated were not managed properly. Palm Oil Mill Effluent (POME) is the wastewater generated by palm oil extraction process. On the other hand, POME is a renewable energy source. To address the need for electrical energy increases, the monitoring of POME is an effort that needs to be studied because POME is no longer a pollutant to the environment but a helpful resource.This study uses field data collection in the form of POME volume and treatment plant process management to determine the COD levels so that the estimation of total biogas can be done. Based on the calculation of the energy potential of POME in Jambi province with  processing capacity of the entire Province amounted to 1,230 tons FFB / hour, 20 hours operating time / day and COD content of 50,000 mg / L, the amount of energy can be obtained is 737.712 MWh / day or 269.26 GWh / Year.Keywords: POME, biogas, energy

Abstract

Laundry wastewater is grey water, which is part of domestic wastewater, which is not through the toilet. Laundry wastewater contains COD, BOD, TSS, Total Phosphate, pH, MBAS which includes derivatives of organic substances so that the accumulation causes an increase in the organic content of water or groundwater. The purpose of this study was to observe the effects of the hydraulic loading rate (HLR) and permeable layer (zeolite and gravel) on the efficiency of decreasing laundry wastewater pollutants. Variations in HLR consist of 500 l / m2 day, 750 l / m2 day and 1000 l / m2 day. In this study, laundry wastewater was introduced gravitationally into the MSL reactor with dimensions of 15x50x50 cm. The MSL reactor consists of impermeable layers and permeable layers. The impermeable layer is a layer consisting of a mixture of soil and charcoal with a ratio of 2: 1, and a permeable layer consisting of layers of gravel (MSL 1) and zeolite (MSL 2) with a diameter of 0.25 - 0.5cm. Based on the results of the study, the HLR and permeable media have an effect on the decrease of laundry wastewater pollutant parameters. The highest decrease in pollutants for COD, BOD, TSS, Total Phosphate, pH, and MBAS parameters was obtained at HLR 1000 l/m2.d with the highest percentage reduction is 95% at MSL 1 and 92% at MSL 2. Decreasing pollutant concentration of laundry wastewater is higher in MSL 2 (permeable layer of zeolite) compared to MSL 1 (permeable layer of gravel).
