Abstract

Peatlands are one type of wetland ecosystem. Indonesia's peat land area is about 14.95 million hectares spread across the island of Sumatra, Kalimantan. Microalgae are photosynthetic microorganisms capable of converting sunlight, water and carbon dioxide into biomass. In microalgae biomass contains beneficial essential ingredients, such as proteins, carbohydrates, lipids and nucleic acids. The microalgae used in this study were the Indigeneous microalgae from peat water. The purpose of this study is to determine the influence of the best variation in the addition of Basal Bold Medium (MBB) to the rate of cell growth and lipid production in the cultivation of microalgae indigeneous of peat water. The medium used for the cultivation of microalgae should be enriched with nutrients that include the nutrient elements of macronutrients (C, H, N, S, P, K, Mg and Ca) and micronutrient nutrients (Fe, Cu, Mn, Zn, Mo, V and Si). The results showed the best conditions gained in the addition of the medium of Basal Bold 1 ml/L, where the lipid content obtained is 29.44%, and the growth rate of cell/ML 825 x 104. Keywords: peat water, lipids, cellular growth rate, Basal Bold Medium

Abstract

Biochar has a large surface area, and a high capacity to absorb heavy metals and can potentially be used to reduce bioavailability and leach of heavy metals as well as organic pollutants in the soil through adsorption. This study aims to determine the effect of adding biochar from rice husks to removal of heavy metals Cd in contaminated soil. Biochar is made using a pyrolysis apparatus with a burning temperature of 500oC for 1 hour. The dose variation used in this study was 10% ; 12.5% ; and 15% with 30 days incubation periods. The results showed that the highest Cd removal occurred at the addition of a 15% dose of biochar, so that the concentration of heavy metal Cd became 10.85 mg/kg with a removal efficiency of 45.45%. Key words: biochar, rice husk, biochar dose, polluted soil, heavy metals

Abstract

Electroplating activities produce small quantities of waste water but the level of toxicity is very dangerous because it contains heavy metals. Chemical parameters measured in this reasearch are Cr (total), Cu, and Ni. The measurement results showed the levels of chemical parameters generally exceeded the quality standard. It is necessary to do an acute toxicity test and bioconcentration factor (BCF) which is one way to monitor the negative impacts of electroplating waste water. This research was using electroplating X wastewater in Pekanbaru City and research aims are determine the LC50 value, TUa value and analyze the relationship between the quality of electroplating X waste water and its toxicity level which is supported by data on the absorption of pollutant metals in the body of test animals (BCF). An acute toxicity test was done by static method within 96 hours using a test animal of baung fish (Hemibagrus sp). The death of baung fish (Hemibagrus sp) was analyzed using the probit method. The LC50 test results were 4,8% and the TUa value was 20,833 with category III namely the level of High Acute Toxicity and BCF values of Cr (total), Cu and Ni were 0,046; 0,000102; 0,00527 with the category of low accumulation value (BCF <1). Keywords: Acute Toxicity Test, Electroplating Waste Water, Baung Fish (Hemibagrus sp), LC50, BCF.

Abstract

Palm oil mills in addition to producing crude palm oil also produce by-products in the form of Palm Oil Mill Effluent (POME). POME contains high amounts of organic ingredients and pollutants. One method that can be applied to treat POME is the High Rate Algae Reactor (HRAR) System. The HRAR system uses microalgae-bacterial consortium that has better performance in removing pollutants in POME and increasing the growth of microorganisms. This research aim by determining the effect of microalgae suspension concentration in the HRAR system towards the removal efficiency of Chemical Oxygen Demand (COD) and total nitrogen. The research was conducted in batch in the HRAR system that equipped with a paddle wheel, by variations of microalgae suspension concentration as 0; 10; 15; 20; and 25 (% v/v). The research was carried out for 7 days and used the sun as a source of light. Based on the research results, 25% of microalgae suspension concentration has the highest microalgae cell density, was 6,34 x 106 cells/mL and showed the best removal efficiency of COD and total nitrogen, were 78.79% and 80.37%.

Abstract

Soil contamination by heavy metals lead (Pb) and cadmium (Cd) is a form of pollution that is very dangerous for living things. One of the efforts to cultivate polluted soil is the remediation method using biochar from rice husks. The purpose of this study was to analyze the effect of biochar particle size variations on the removal of heavy metals Pb and Cd on contaminated soil. Biochar is made by pyrolysis at 500 0C for 1 hour and flows 0.1 L / minute of N2 gas. This study used a variety of biochar particle sizes of 100 mesh, 60 mesh, 40 mesh and testing time every 10 days for 1 month. The results of this study were the highest Pb and Cd removal in the addition of biochar with a particle size of 100 mesh, namely with a Pb concentration of 91.32 mg / kg and a removal efficiency of 54.05% ; Cd concentration of 10.47 mg / kg and a removal efficiency of 47.36%. Based on the results obtained, it can be stated that the smaller the biochar particle size, the efficiency of heavy metal removal will increase.

Abstract

Limbah cair pabrik kelapa sawit meskipun sudah diolah, limbah yang dibuang ke sungai masih belum memenuhi baku mutu yang ditetapkan. Untuk itu diperlukan alternatif pengolahan secara alami dengan metode fitoremediasi yang memanfaatkan tanaman Typa Latifolia. Fitoremediasi merupakan salah satuteknologi yang secara biologi yang memanfaatkan tumbuhan atau mikroorganisme yang dapatberasosiasi untuk mengurangi polutan lingkunganbaik pada air, tanah dan udara yang diakibatkanoleh logam atau bahan organik. Penelitian bertujuan untuk melihat kemampuan sistem fitoremediasi dengan tanaman Typa Latifolia dalam mengolah kandungan COD dengan variasi kerapatan tanaman, kadar limbah, dan waktu tinggal. Pada penelitian ini digunakan bak plastik ukuran 50cm x 36cm x 31cm, media tanah dengan ketebalan 10cm, media pasir ketebalan 5cm, dan media kerikil setebal 5cm dengan variasi kerapatan tanaman Typha latifolia (0,5g/cm2; 0,75g/cm2; dan 1g/cm2), variasi kadar limbah cair kelapa sawit (20%; 60%; dan 100%), dan variasi waktu tinggal (5 hari dan 9 hari). Parameter yang dianalisis adalah COD, dengan konsentrasi sebelum pengolahan sebesar 2820-3980 mg/l, sedangkan setelah diolah konsentrasinya turun menjadi 720-2720 mg/l pada hari ke 5 dan 80-2340 mg/l pada hari ke 9. Hasil ini menunjukkan bahwa metode fitoremediasi menggunakan Typha latifolia mampu menyisihkan konsentrasi COD limbah cair pabrik kelapa sawit. Secara umum, variasi kerapatan tanaman, kadar limbah, dan waktu tinggal memberikan pengaruh yang signifikan untuk penurunan COD. Kerapatan tanaman 1 g/cm2, kadar limbah 20%, dan waktu tinggal 9 hari memberikan efisiensi tertinggi untuk masing-masing parameter pencemar. Secara keseluruhan efisiensi penyisihan BOD, COD, dan TSS yang diperoleh pada penelitian ini pada hari ke 5 berkisar antara 31,66-74,65% dan pada hari ke 9 berkisar antara 41,21-97,18%.Kata Kunci: Limbah Cair Pabrik Kelapa Sawit, Fitoremediasi, Typha latifolia, Kerapatan Tanaman, Kadar Limbah
