Item Concentration and Distribution of Heavy Metals Pb, Cu and Zn in Seawater, Sediment and Snail Telescopium telescopium Around Shipyards in Batam(2016-03-22) Amin, Bintal; Nurrachmi, Irvina; Kennedy, LeoA study on the concentration and distribution of heavy metals Pb, Cu and Zn in seawater, sediment and Snail Telescopium telescopium from coastal waters around shipyards in Batam has been conducted. Samples were taken from four stations and heavy metal analysis was carried out by using AAS Perkin Elmer 3110 in Marine Chemistry Laboratory Faculty of Fisheries and Marine Science University of Riau. The mean concentrations of Pb, Cu and Zn were 0.424; 0.057; 0.057 mg/L in seawater, 45.392; 129.688; 181.325 μg/g in sediment and 49.271; 87.663; 138.900 μg/g in T. telescopium, respectively. Higher concentration of Pb in T. telescopium than in sediment and seawater was found, whereas Cu and Zn were higher in sediment than in snail and seawater. Concentrations of Pb, Cu and Zn in seawater were possitively correlated with those in both sediment and snail and concentrations of those metals in sediment were also possitively correlated with those in snail. In general, the concentrations of Pb, Cu and Zn in coastal water around shipyard in Batam was higher than in coastal waters with no shipyard industry and they were still generally comparable to those reported values in regional studies. Mean concentration of Pb in sediment was nearly reach the ERL values whereas Cu and Zn already exceeded the ERL but still lower than ERM values. Continuous environment monitoring programs should be implemented.in Batam coastal waters since rapid developments in many infrastructure and industry sectors is taking placeItem DISTRIBUSI SPASIAL HIDROKARBON DAN KELIMPAHAN DIATOM DI PERAIRAN PANTAI SEKITAR KAWASAN INDUSTRI PERMINYAKAN(2013-05-30) Amin, Bintal; Nurrachmi, Irvina; Damanik, FinriA survey on the oil content and diatom abundance has been conducted in the coastal water around oil industry activities. Two locations (Sungai Pakning and Selat Lalang) with three s tations each were selected for the sampling. Oil content analysis and identification of diatom were carried out in Marine Chemistry Laboratory and Marine Biology Laboratory , Faculty of Fisheries and Marine Science, University of Riau. The results showed that all water quality parameters measured in the present study were still in the range of tolerable levels for the survival of marine organisms. The mean oil content varies from 0.35 to 0.37ppm and diatom abundance ranged from 1433.33 – 1566.67cel/L consisted of 10 species in Sungai Pakning whilst oil content in Selat Lalang ranged from 0.34 to 0.54 ppm and diatom abundance 1813.33 – 2200.00 cel/L with 7 spesies. Oil contents found at the stations closed to oil industry were generally higher than that at the stations far from any oil-related activities. In both locations, the oil contens were measured to be higher during high tide when compared to low tide. The increase of oil content in the waters was followed by the decrease in diatom abundance. Simple linear regression analysis indicates negative correlation between oil content and diatom abundance (Y = 2620 – 3000X; r = 0.4878and Y = 3546 – 5885X; r = 0.9110 in Sungai Pakning and Y = 3098 – 1947X; r = 0.7113 and Y = 2775 – 2152X; r = 0.3347 in Selat Lalang respectively ) during high and low tides.Item KAJIAN DAMPAK INDUSTRI PERMINYAKAN TERHADAP KUALITAS FISIKA KIMIA DAN BIOEKOLOGI PERAIRAN PANTAI(2013-05-30) Amin, Bintal; Nirrachmi, Irvinasurvey on the oil content and diatom abundance has been conducted in the coastal water adjacent to oil industry activities.

Peningkatan jumlah penduduk dan berbagai aktivitas manusia di kawasan pantai menyebabkan wilayah ini sering digunakan sebagai tempat pembuangan akhir yang dapat menyebabkan peningkatan jumlah limbah termasuk yang mengandung logam berat sehingga pada akhirnya dapat mengganggu keseimbangan biogeokimia perairan laut terutama di zona pantai. Masalah pencemaran logam berat semakin banyak mendapat perhatian masyarakat sejak beberapa tahun yang lalu. Hal ini disebabkan kekhawatiran masyarakat akan terjadinya kasus keracunan logam berat. Pencemaran laut oleh logam berat mulai mendapat perhatian sejak tahun 1953. Pada periode 1953-1960 sekitar 146 nelayan di Desa Minamata -Jepang meninggal dan cacat tubuh karena mengkonsumsi ikan yang telah tercemar oleh raksa (Hg) yang kemudian menyusul kasus pencemaran kadmium (Cd) yang juga terjadi di Jepang. Beberapa tahun kemudian terjadi pula pencemaran raksa di beberapa negara seperti Irak pada tahun 1971, Venezuela pada tahun 1974, 60 60 Pidato Pengukuhan Guru Besar Tetap Prof. Dr. Ir. H. Bintal Amin, M.Sc Kanada pada tahun 1975, Swedia, Amerika Serikat dan negara-negara Eropa lainnya (Clark, 1989). Sejak saat itu kasus pencemaran raksa sudah menyebar secara luas dan sering menjadi masalah yang serius yang perlu mendapatkan perhatian khusus. Di Indonesia, perairan Teluk Jakarta dan Teluk Buyat beberapa waktu yang lalu juga sempat diisukan telah terjadi pencemaran logam berat.Item Potensi Gastropoda Intertidal Sebagai Biomonitor Pencemaran Logam Berat Di Perairan Pantai Tropis(2015-01-22) Amin, BintalPemanfaatan laut bagi kesejahteraan manusia semakin meningkat sejalan dengan bertambahnya populasi manusia. Peningkatan jumlah penduduk dan berbagai aktivitas manusia di kawasan pantai menyebabkan wilayah iru sering digimakan sebagai tempat pembuangan akhir yang dapat menyebabkan peningkatan jumlah limbah termasuk yang mengandung logam berat sehingga pada akhimya dapat mengganggu keseimbangan biogeokimia perairan laut terutama di zona pantaiItem Skrining Bakteri Hidrokarbonoklastik Dalampeningkatan Degradasi Minyak Bumi Dari Gas Bootpetapahan, Riau(wahyu sari yeni, 2019-01-09) Sayuti, Irda; Siregar, Yusni Ikhwan; Amin, Bintal; Agustien, AnthoniThe research about Hydrocarbonoclaustic bacterial screening studies from the Gas boot area exploration Gathering Station (GS) of PT. Chevron Pacific Indonesia Petapahan Riau has done. The study aims to find hydrocarbonoclastic bacteria and test its ability to degrade petroleum. The research was carried out by the experimental method. The first step is isolating bacteria from the Gas boot. Isolation results obtained 4 bacterial isolates that were suspected as Hydrocarbonoclastic bacteria. The second stage is screening to prove the ability of these bacterial isolates to degrade petroleum. The screening method is done by growing bacterial isolates on 2% SMSS + petroleum media. The screening results showed 4 bacterial isolates were Hydrocarbonoclastic bacteria because it was known to be able to degrade petroleum hydrocarbons marked by a decrease in TPH and COD levels. The highest degradation rate of TPH and COD was shown by bacterial isolates IMB-03 with degradation rates of 39.23% TPH and 37.98% COD
