TPA Sei Nam Kijang merupakan TPA yang menggunakan sistem sanitary landfill dalam pengelolaan sampah. Kolam penampungan air lindi di TPA tersebut kurang berfungsi dengan baik terlihat dari warna air lindi hitam coklat kepekatan, terdapat lumut dipermukaan air lindi, dan masih tercium bau yang menyengat. Penelitian ini bertujuan untuk mengetahui efektifas kombinasi pasir zeolit dan arang aktif dalam mereduksi parameter fisika dan kimia pada air lindi. Hasil menunjukan bahwa kombinasi arang aktif dan pasir zeolit efektif dalam menurunkan kadar BOD, COD, N total, TSS dan pH air lindi pada tiga jenis ketebalan. Efektifitas tertinggi dalam menurunkan TSS adalah ketebalan 10cm sebesar 11,76%. Efektifitas tertinggi dalam menurunkan kadar pH, COD, BOD dan N total adalah ketebalan 20cm sebesar 19,6%, 22,6%, 35,5% dan 33,33%. Untuk Hg dan Cd, proses filtrasi untuk setiap ketebalan tidak efektif dalam menurunkan kadar logam berat tersebut.Sanitary landfill is used method for municipal solid waste (MSW) disposal in Sei Nam Kijang dumpling land. Leachate evaporation pond in a landfill site is not working properly which can be seen from the dark brown color of leachate, the moss on the surface of leachate water, and the odor. This study aims to determine the effectiveness of a combination of zeolite sand and activated charcoal in reducing physical and chemical parameters in leachate with variations in thickness used, namely 10 cm, 15 cm, and 20 cm. The results showed that the combination of activated charcoal and zeolite sand is effective in reducing levels of BOD, COD, total N, TSS, and pH of leachate water in all three types of thickness. The highest effectiveness in reducing TSS is 10cm thickness of 11.76%. The highest effectiveness in reducing total pH, COD, BOD and N is 20cm thickness by 19.6%, 22.6%, 35.5% and 33.33%. For Hg and Cd, the filtration process for each thickness is not effective in reducing levels of heavy metals.

Bengawan Solo merupakan sungai yang sudah banyak mengalami perubahan oleh Waduk, Bendungan, Sodetan, dan lain-lain. Bengawan Solo melewati Provinsi Jawa Tengah dan Jawa Timur yang padat penduduk, sekitar 15,2 juta jiwa berdomisili di satuan wilayah Sungai Bengawan Solo dan juga banyak terdapat industri. Permasalahan tersebut dapat berpengaruh langsung terhadap kehidupan organisme air kajian tentang parameter físika-kimia perairan diharapkan dapat memberikan informasi tentang status kualitas perairan di Bengawan Solo. Parameter yang diamati dalam penelitianini adalah oksigen terlarut, karbondioksida, pH, fenol, minyak-lemak, amonia, Cd, Cr, Zn, Pb, Cu, dan CN. Terdapat indikasi bahwa Bengawan Solo di daerah Solo-Sragen dan sekitarnya telah tercemar bobot dengan kualitas air buruk yaitu oksigen rendah (beberapa lokasi kurang dari 2 mg/L, karbon dioksida tinggi (8,8-34,32 mg/L), NH3-N bebas tinggi (beberapa lokasi lebih dari 0,2 mg/L), COD tinggi (1,64-172 mg/L), fenol tinggi (0,087-1,431 mg/L), minyak lemak tinggi (2,6-54,6 mg/L).Konsentrasi logam bobot pada beberapa lokasi yaitu Kampung Sewu, Bak Kramat, dan Tundungan cukup tinggi yaitu Cr= 0,180- 0,375 mg/L, Cu=0,026-0,293 mg/L, dan Zn=0,515-2,892 mg/L. Demikian juga kandungan logam bobot pada ikan sapu-sapu (Liposarcus pardalis) cukup tinggi pada beberapa lokasi Kampung Sewu, Tundungan, Bak Kramat, dan Butuh; Cr=0,856- 2,154 mg/kg, Cu=3, 69-198,48 mg/kg, Pb=1,067 - 2,006 mg/kg, dan Zn=53,516-102,285 mg/kg. Perlu dilakukan pengendalian pencemaran di Bengawan Solo dengan cara meningkatkan kesadaran bersama, pemantauan pembuangan limbah, dan penindakan bagi para pelanggaran. Bengawan Solo River is highly modified by dams, impoundment, reservoir, channelization, etc. It traverse through Central Java and East Java province in its passage from headwaters to the sea. Industries and heavy population (approximately 15.2 million people) near the river have potentially wreaked havoc upon the river. Study on physical and chemical parameters expected provide enough information on water quality condition in Bengawan Solo River. Parameters under study were disolved oxygen, carbondioxid, pH, fenol, NH3-N, oil, and grease, COD, Cr, Cd, Pb, Zn, Cu, and CN. An overview of water quality of Bengawan Solo River in Solo-Sragen region indicates that the segments is already strongly polluted as indicated as low oxygen (some location less than 2 mg/L) and high amount of CO2 (8,8-34.32), high free NH3-N (some location more than 0,2 mg/L), COD (1,64-172 mg/L), fenol (0.087- 1,431 mg/L), and oil and grease (2,6-54.6 mg/L). Heavy metals content of some location at Kampung Sewu, Bak Kramat, and Butuh were Cr=0,180-0,375 mg/L, Cu=0,026-0,293 mg/L, Zn=0,515-2,892 mg/L. Heavy metals content in fish tissue of sapu-sapu were high enough at some location (Kampung Sewu, Tundungan, Bak Kramat, and Butuh); Cr=0,856-2,154 mg/kg, Cu=3,69-198,48 mg/kg, Pb=1,067- 2,006 mg/kg, and Zn=53,516-102,285 mg/kg.

The aim and objective of the study was to isolate and characterize heavy metal tolerant microorganisms from tannery effluents. Six effluent samples were collected aseptically and their physical and chemical parameters were determined. A total of 40 bacterial colonies were isolated from these effluent samples. Among them, six bacterial isolates were characterized provisionally as Alcaligenes aquamarinus, Bacillus coagulans, Bacillus firmus, Enterobacter cloacae, Pseudomonas alcaligens and Pseudomonas mendocina based on morphological, cultural and biochemical characteristics. The survibality and tolerance to heavy metals (Cr and Cu) of these isolates were examined. All the isolates were found to grow at high concentration of CuSO4 (95ppm/ml) and varying degrees of chromium (K2Cr2O7). The highest tolerance was shown by Alcaligenes aquamarinus. These heavy metal tolerant organisms could be potential agents for bioremediation of heavy metals polluted environment.Bangladesh J Microbiol, Volume 29, Number 1, June 2012, pp 23-26

The present study was conducted in Salt marshes and Salt pans in central parts of Iran. 121 specimens of ants were collected by trapping and hand during spring, summer and autumn 2017 to 2019. Nine species belong to two subfamilies of Myrmicinae and Formicinae were identified. The vegetation, physical and chemical parameters of soil such as salinity, Ph, and other factors were investigated. Darband Shoor Mountain station with five species had the highest diversity and vegetation density and the lowest salinity of soil (72.14 ds/m) whereas Salt Lake station had only one species, with no vegetation and the highest salinity of soil (153.15 ds/m). Cataglyphis lividus (André, 1881) was the dominant species in all the stations except in Darband Shoor Mountain station. All the species were reported for the first time from salt marshes and salt pans in the central parts of Iran and were approved by Prof. Brian Taylor, in Royal Entomological Society of London, England.
