This study aimed to determine the concentration of heavy Cu and Pb in seawater and sediment in coastal waters Loli subdistrict Banawa, district Donggala. The method used was destruction and using Atomic Absorption Spectrophotometer (AAS) instrument.Samples of seawater and sediment were taken by two sampling points. Samples were destructed by using a solution of HNO3 and HClO4with ratio 4: 1. Levels were measured at a wavelength of 325.7 nm for Cu and 217 nm for Pb. The analysis result obtained that the levels of Pb in the seawater in the range of 0,531-0.671 mg/L, while for Cu in the range of 0.009-0.090 mg/L it can be concluded that the levels of Pb and Cu in seawater has exceeded the levels were of 0,008 mg/L. For sediment samples obtained that Pb levels were around 1,78-7,73 mg/kg while for Cu 15.86-68.88 mg/kg so Cu in sediment was up to 30 mg/kg while the levels of Pb did not exceed the tolerance limits of 33 mg/kg.

This research was conducted at North Bintan island waters. The sample of sediment and snail S. canarium hasbeen taken from four locations those were Busung, Lobam, Sebung, and Tanjung Bakau coastal waters. Analysisof metal concentrations both in sediment and snail conducted by using Atomic Absorption Spectrophotometer(AAS)Solar 969 AA. The result showed the highest concentration of Cadmium (Cd) and Cuprum (Cu) in sediment whichwere 0.51 ppm (Cd) and 13.22 ppm (Cu). While the highest concentration of these metals in snail S. Canarium wichwere 0.56 ppm (Cd) and 8.42 (Cu), indicating that the concentration in both sediment and snail still below thenormal threshold. It could be concluded that the Bintan Coast has not been polluted but lightly contaminated.

Abstract The concentration of heavy metals (HMs) camium (Cd), cuprum (Cu), chromium (Cr), nickel (Ni), lead (Pb), and zinc (Zn) in sediments of Makassar Strait was investigated. We collected sediment samples from 28 research stations. Atomic Absorption Spectrophotometer (AAS) was used to measure HMs in all samples. This research aims to know the levels of HMs’ contamination and pollution in sediments. The analysis revealed that the concentration of all HMs is still low and inlined with the sediment standard guidelines, exception of Cu and Ni. In regards to the value of I_geo and PLI, sediment in the Makassar Strait is still normal for marine life, and sediment is included in unpolluted categories (PLI<1). The sources of HMs in this strait come from human activities in the land of Kalimantan and Sulawesi Island.

The aims of this research are to analyze the content of Lead in blood cockle (Genus: Anadara) at West Lombok Labuhan Tereng coastal waters. The content of lead in sediment and clams was analysis at Mataram University Analytical Laboratory by using wet digestion method and measured using atomic absorption spectrophotometer (AAS) in 283.3 nm wavelength. The results then compared with the sediments and clams standards applicable. Results of Pb in the sediment measurements show that the highest lead levels is 30.66 mg/kg found in around Dusun Cemara coast. The results obtained are still at the level targets under Dutch Quality Standards for Metals in sediments (IADC / CEDA), 1997. The highest Pb levels in blood clams is 13,075 mg/kg contained by a medium-sized (3.08 cm) of species A. antiquata around Kebon Talo estuary. These results are indicate that the levels of Pb in blood cockle is already distant exceeded the threshold of consumption under Indonesian National Standar, 2009 which is equals to 1.5 mg/kg, so the clams blood in coastal waters Labuhan Tereng should not be consumed greatly overheated because the accumulative character of Pb can be harmful for health.Keywords: Blood cockle, sediment, acumulation, lead

The article is focused on estimation of Zinc in the roadside forages, and blood of buffaloes feeding on these forages. This study was carried out in Sargodha during December 2015 to January 2016 (winter) and May 2016 to June 2016 (summer). Five road sites (Mateela, Faisalabad roadside, Shaheenabad roadside, Bhalwal roadside and 50 chak) were selected from sampling of forages, soil and buffalo blood sample. Heavy metal analysis of all digested samples was done with atomic absorption spectrophotometer. Analysis of variance and correlation was done with two way ANOVA. This study regarding the accumulation of zinc in forages, soil and the buffalo blood would help the authorities to exactly determine the agents which are responsible for increasing pollution in the environment.

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

Penelitian bertujuan untuk mengkaji status mineral sapi potong yang dipelihara pada daerah aliran sungai (DAS) Jragung-Tuntang-Serang-Lusi-Juwana (Jratunseluna). Kajian menggunakan metode survei yang melibatkan 30 ekor sapi potong yang dipelihara di dataran rendah dan tinggi DAS Jratunseluna. Pemilihan sapi dilakukan sesuai teknik sampling acak secara purposif. Observasi status Zn didasarkan atas konsentrasi Zn pada tanah, air minum, pakan, dan bulu ternak. Penetapan kadar Zn pada sampel menggunakan atomic absorption spectrophotometer. Parameter data antara daerah dataran rendah dan tinggi dibandingkan menggunakan uji t. Konsentrasi Zn pada tanah dataran rendah dan tinggi masing-masing adalah 17,03 dan 78,25 ppm. Konsentrasi Zn pada pakan dari daerah dataran rendah dan tinggi sangat beragam. Konsentrasi Zn pada bulu ternak di dataran rendah dan tinggi masing-masing adalah 86,01 dan 81,19 ppm. Kadar Zn pada air minum tidak terdeteksi secara jelas baik di dataran endah maupun dataran tinggi. Konsentrasi Zn pada tanah dan pakan di daerah dataran rendah dan tinggi dapat dikategorikan sebagai kadar sedang sampai tinggi. Namun, data kadar Zn pada bulu ternak menunjukkan bahwa sapi potong yang dipelihara baik di dataran rendah dan tinggi ternasuk defisien ringan.
