STUDI PENURUNAN KADAR LOGAM BESI (Fe) DAN LOGAM TEMBAGA (Cu) PADA AIR EMBUNG MENGGUNAKAN ADSORBEN NANOSILIKAABSTRAKPolusi limbah logam berat dalam air merupakan satu permasalahan lingkungan yang penting. Dalam mengatasi permasalahan tersebut dapat dilakukan purifikasi terhadap air tersebut. Metode yang dapat digunakan untuk purifikasi limbah sangat beragam salah satunya adalah absorpsi. Secara umum metode absorpsi telah banyak digunakan dalam purifikasi air limbah. Metode absorpsi dapat menurunkan kadar logam yang terlarut pada limbah. cair dengan cara menyerap logam-logam tersebut ke dalam permukaan absorbennya. Tujuan dilakukan penelitian ini adalah  untuk menurunkan konsentrasi logam besi (Fe) dan tembaga (Cu) menggunakan adsorben nanosilika. Penelitian ini menggunakan variabel bebas yaitu waktu pengadukan (20 menit, 40 menit, dan 60 menit). Hasil akhir filtrat air embung kemudian diukur absorbansinya menggunakan Spektrofotometer Serapan Atom. Berdasarkan hasil analisa menggunakan instrumen SSA diperoleh hasil bahwa tidak terjadi penurunan logam Fe maupun Cu. Dalam hal ini terjadi peningkatan konsentrasi dalam logam Fe maupun Cu, hal ini dikarenakan kurangnya waktu pengadukan dan pengaruh dari adsorben nanosilika.Kata Kunci: limbah, logam berat, nanosilika STUDY OF DECREASING METALS IRON (Fe) AND COPPER (Cu) ON EMBUNG WATER USE OF NANOSILICA ADSORBEN ABSTRACTHeavy waste pollution of heavy metals in the water is an important environment issue. To solve the problem, its can be purified the water. The methods that can be used for waste purification are very diverse, one of which is absorption. In general, the method of absorption has been widely used in wastewater purification. The absorption method can decrease dissolved metal content in the waste. liquid by absorbing the metals into the absorbent surface. Research has been conducted to reduce the concentration of iron (Fe) and copper (Cu) by using nanosilica adsorbent. This research used to independent variable that is stirring time (20 minutes, 40 minutes, and 60 minutes). The final result of filtrate embung water then measured its absorbance using Atomic Absorption Spectrophotometer (AAS). Based on the result of the analysis using SSA instrument, it is found that there is no decrease of Fe and Cu metals. There are several reasons for those problem such as due to lack of stirring time and the influence of nanosilica adsorbent.Keywords: Waste pollution, heavy metal, nanosilica

Background: Hazardous materials, such as used batteries contain heavy metals and enter the solid waste stream, ending up in landfills. The present study was done to determine the amount of used batteries in Iran and their heavy metal contents in the batteries entering the landfill site in Tabriz. Methods: A questionnaire was applied to assess the current management condition of the used batteries in Tabriz and Ardabil as the representative cities of the entire country. The heavy metal content of 15 AA-sized batteries was determined by inductively coupled plasma. Results: Our findings showed that 14.7% of the used batteries in Iran have been imported, and approximately 76% and 24% of the batteries analyzed at the landfill site were AA-sized and cellphone batteries, respectively. In 60% of the studied batteries, the total heavy metal content was less than 100 mg/kg. Conclusion: The results of this study could be a useful reference for global and local policymakers in developing effective regulations for the use of cleaner materials in the battery industry and controlling the used batteries from their generation to the end of the battery life

Msw Compost

AbstractThere are more than 522 towns and cities in Bangladesh, which generate thousands of tons of solid waste known as Municipal Solid Waste. Low collection coverage and disposal facilities are responsible for unsatisfactory waste management. The composting technology is a good alternative method for managing MSW. The present study was conducted to assess the quality of the MSW compost produced from the solid wastes of Mymensingh Pourashava. For quality assessment physical, chemical and biological properties of prepared compost namelye bulk density, porosity, water-holding capacity, moisture content, pH, organic matter content, C:N ratio, NPKS content, buffering capacity, soluble salts content, heavy metal content and the presence of harmful organisms in the MSW compost were studied. The results indicated that the MSW compost was matured and stable having pH 7.3 and buffering capacity of the MSW compost were good but the organic matter content and C : N (14.5) ratio were low. The N, P, K and S content of the MSW compost were 0.9, 0.3, 0.4 and 0.45 percent of the total volume. The soluble salts content and heavy metal content of the compost were found to be within the permissible limits. The MSW compost contained no E. coli and Salmonella. From the results, it can be concluded that, the composting could produce acceptable quality of compost, which can be used as fertilizer or soil amendment.

Eichhornia crassipes is well-known as water hyacinth. Water hyacinth grows rapidly in the nutrient-rich water and high light intensity places. The uncontrollable growth of water hyacinth has caused many negative impacts to the environment. For instance, interrupted water transport and decreased population of aquatic lives. The capacity of utilising water hyacinth is slower than water hyacinth growth and water hyacinth is still considered as a threat to theecosystem. This work was focused on the study of the pharmacological activity and heavy metal content of water hyacinth in Lake Cipondoh, Tangerang. Fresh water hyacinth was pre-treated through oven-drying and milling process. After that, each part of the plant was macerated by using multiple extraction method with 96% ethanol/water and three variations of sample-to-solvent ratios (1:30, 1:50, and 1:75 w/v). The result of the experiment showed thatwater hyacinth leaves produced an extract with lowest IC 50 (55.76 ± 6.73 ppm) compared toother parts. The most optimum solvent used to achieve this result was 96% ethanol/water (1:1 v/v). In order to obtain the lowest antioxidant activity, the sample to solvent ratio used was 1:50 and the heavy metal in the extract was very low. With this result, it was concluded that there is a promising opportunity to apply the water hyacinth growing in Lake Cipondoh, Tangerang as herbal medicine ingredient. Through this utilization, the overall number of water hyacinth in Indonesia can be reduced or at the least be controlled, so that the environmental problem caused by this plant can be minimized.
