Phytoplankton plays an important role in primary productivity in marine environment. Various environmental changes in coastal area will impact the water quality and their phytoplankton compositions. The purpose of this study is to examine the abundance of phytoplankton from two different sites, i.e Tanah Merah (close to mining site) and Semujur Island (away from mining site) in Bangka Island. Phytoplankton and water sample were collected on June- August 2018. Water quality was measured using water quality checker, whereas the phytoplankton was identified under the microscope with a magnification of 100x. Non-parametric Kruskal test and T-test analysis was performed to determine the abundance, diversity, uniform, and dominance of phytoplankton between Sites, respectively. Statistical analyses showed the abundance of phytoplankton at Semujur Island was significantly higher than that at Tanah Merah (p = 0.003). In additions the diversity, uniform, and dominance were also significantly different between sites (all p <0.05). In Semujur Island, Diatoms (Thalassiothrix, Chaetoceros and Thalassionema) were more dominants than the Dinophyceae group. However, in Tanah Merah, the genera Ceratium belong to class Dinophyceae was more dominant than the class Bacillariophyceae. These results performed that the phytoplankton in Tanah Merah and Semujur Island was affected by environment, in this case the mining area. The water quality in Semujur Island (non-mining Area) might have good quality than in Tanah Merah (mining area). The average value of turbidity and Total Suspended Solid in Tanah Merah Waters causes low abundance of phytoplankton. It can be concluded that tin mining can disrupt the abundance and composition of phytoplankton as a primary producer of waters.

The study examined the effect of sub-lethal level of Linear Alkylbenzene Sulphonates (LAS) on some selected electrolyte and metabolic indices of juvenile Heterobranchus bidorsalis. The fish were exposed to varying concentrations of LAS (0.00 mg/L, 0.01 mg/L, 0.02 mg/L and 0.03 mg/L, respectively) in a semi-static tank for 14 days. The chemical test analysis of LAS showed that only total suspended solid (196.8 mg/L), total alkalinity (56.1 mg/L) and nitrate (7.9 mg/L) exceeded Federal Environmental Protection Agency (FEPA) and Standard Organization of Nigeria (SON) permissible limits. Conductivity and dissolved oxygen (DO) of the water parameter differ significantly (p < 0.05) from the control and among dose concentration. Electrolyte values (K+ and Ca2+) were not significantly (p > 0.05) different at all level of LAS concentration. However, there were significant (p < 0.05) differences in Na+ concentration. The highest value for Na+ (16.00 + 1.16 Mmol/L) was obtained at 0.02 mg/L, while the least (5.35 + 0.45 Mmol/L) was recorded in the control at 0.00 mg/L. There was significant (p < 0.05) differences in values of urea in the experimental group, except between 0.01mg/L (1.53 + 0.05 mg/dm) and 0.02 mg/L (1.60 + 0.06 mg/dm). On the contrary, there were significant (p < 0.05) differences in all the values of creatinine recorded in this study. The values increased down the experimental group in a dose dependent pattern. The highest value of creatinine (54.45 + 4.96 mg/dm) was recorded at 0.03 mg/L dose concentration while the least (30.47 + 7.65 mg/dm) was obtained in the control (0.00 mg/L). The present study concluded that LAS has impact on the metabolites and electrolytes especially creatinine and the Na+. Therefore, LAS could be very toxic at high concentrations and as such, indiscriminate discharge of LAS effluent into aquatic environment should be averted.

Abstract- Tello River water used by PT. PLN SULTANBATARA for sanitation and process water. One of the process's water is boiler feed water. River water has fluctuative characteristics depending on the season that occurs such as turbidity and Total Suspended Solid (TSS). The presence of TSS in boiler feed water needs to be minimized as it can decrease boiler performance in generating heat. The concentration of TSS in river water can be removed by coagulation and flocculation method with the addition of coagulant. Excessive coagulant distribution will increase the concentration of dissolved solids (TDS) of water. Thus, it is necessary to determine the optimum concentration of coagulant based on initial TSS concentration of river water. The objective of this research is to determine the optimum concentration of Aluminum Sulfate (Al2(SO4)3) and PAC (Poly Aluminum Chloride) Coagulant in reducing TSS water of Tello River. The sample used in this research is Tello river water which has an initial TSS concentration of 150 mg/L. The coagulant used was Aluminum Sulfate and PAC with several concentration variation of 5% - 40% to the initial TSS concentration of river water. Analysis of TSS content of samples using Gravimetry method. The optimum concentration of coagulant Aluminum Sulfate and PAC was 35% and 25% to the initial TSS concentration of river water where the final concentration of TSS obtained was 20 mg/L and 15.5 mg/L with percent TSS removal of 86.67% and 89.6 %. Keywords:      Total Suspended Solid, Coagulation, Aluminium Sulfate, Poly Aluminium Chloride (PAC)

The aims of this research are to find the dominant pollutants in estuarine of Way Tomu and Way Lela, determine the water quality in the estuary Way Tomu and Way Lela, and comparing the effects of the density of settlement on water quality of estuary Way Tomu and Way Lela. The research was conducted in October until November 2015. The method used was survey method with variables the physical parameters (Total Dissolved Solid, Total Suspended Solid, temperature), chemicals parameter (detergents, nitrate, nitrite, pH, BOD, COD, DO, amonia, phosphate, iron, oil and fat, manganese, coopper) and biology parameter (E. coli) class II. The result showed that the dominant chemicals parameter and affect water quality in the Way Tomu is Detergent (746 mg/L), while for the Way Lela estuary are detergent (835 mg/L), phosphate (0,4631 mg/L), and dissolved oxygen (3,2 mg/L), and biological parameters i.e., E. coli. These values have exceeded the value of the quality standard of the water quality is appropriate Government Regulation Number 82 the Year 2001 about Water Quality Management and Control of Water Pollution Classes II. It is thought to be due to the behavior of the people who live the area of the riverbanks of Way Lela and Way Tomu that their household trash into the river. For that is a need for the attention of the Government and local communities to improve the quality of the river water in the Way Tomu and Way Lela with improving the environment-friendly behavior. Keywords: pollutants, pollution estuary, way Tomu, way Lela   ABSTRAK Tujuan dari penelitian ini adalah untuk menemukan polutan yang dominan di muara Way Tomu dan Way Lela; menentukan kualitas air di muara Way Tomu dan Way Lela; serta membandingkan efek dari kepadatan pemukiman terhadap kualitas air muara Way Tomu dan Way Lela. Penelitian ini telah dilakukan pada bulan Oktober sampai November 2015. Metode yang digunakan adalah metode survei dengan variabel penelitian berupa parameter fisik (Total Dissolved Solid, Total Suspended Solid, suhu), parameter kimia (deterjen, nitrat, nitrit, pH, BOD, COD, DO, amonia, fosfat, besi, minyak, dan lemak, mangan, tembaga) dan parameter biologi (E. coli) kelas II. Hasil penelitian menunjukan bahwa parameter kimia yang dominan dan mempengaruhi kualitas air di muara Way Tomu adalah Deterjen (746 mg/L) sedangkan untuk muara Way Lela adalah Deterjen (835 mg/L), Fosfat (0,4631 mg/L), dan Oksigen terlarut (3,2 mg/L), serta parameter biologi yaitu E. coli. Nilai-nilai ini telah melampaui nilai baku mutu kualitas air Sesuai Peraturan Pemerintah Nomor 82 Tahun 2001 tentang Pengelolaan Kualitas Air dan Pengendalian Pencemaran Air Kelas II. Hal ini diduga sebagai akibat perilaku masyarakat yang tinggal di daerah bantaran Way Tomu dan Way Lela yang membuang limbah rumah tangga ke sungai. Untuk itu perlu adanya perhatian pemerintah dan masyarakat setempat untuk memperbaiki kualitas air sungai di Way Tomu dan Way Lela dengan meningkatkan perilaku ramah lingkungan. Kata Kunci: bahan pencemar, pencemaran muara sungai, way Tomu, way Lela
