Abstract

The concentration of three heavy metals Pb, Cd and Hg ware measured in Bone River, Gorontalo sediment. The heavy metal pollution on sediment in Bone River have not been explored longitudinally. The samples were taken in July 2021 at 8 stations.  The trend of metals ware observed in sediment as PbCdHg. The level of studied metals Cd and Hg did not exceed the safe limit by ANZECC, OSQG LEL and CCME TEL meanwhile Pb was met the limit by by ANZECC. However, the investigated showed that fluctuations due to differences in the characteristics of each location. Contamination factor (CF) and geoaccumulation index (Igeo) demonstrated that the sediment samples were low contamination and lightly polluted. Contamination by heavy metals in the Bone River implies that the conditions are much frightening for the biota and residents around the river.

Abstract

Lead is a kind of non-essential heavy metals included in the metal causing environmental pollution with persistent properties that might harm the consumers. This study aimed to determine the best method for reducing the lead level on the freshwater snail Filopaludina javanica using three various water treatment models. Soaking water treatment (6h, 12h, 18h, 24h), flowing water treatment (6h, 12h, 18h, 24h), and refreshing water treatment (6h, 12h, 24h). The lead level assay in both samples used Atomic absorption spectroscopy (AAS), and the physical and chemical parameters were measured, such as temperature, pH, and Dissolved Oxygen (DO). The lowest value of lead content on freshwater’s soft body snail and water sample respectively were soaking water treatment at 6h (0.64 ± 0.02 mg L-1) and 24h (0.0045 ± 0.0015 mg L-1); flowing water treatment at 24h (0.04 ± 0.007 mg L-1) and 18h (0.0036 ± 0.0009 mg L-1) and; refreshing water treatment at 24h (0.150 ± 0.011) and 12h (0.007 ± 0.001), with control 0.072 ± 0.00 mg L-1 and 0.067 ± 0.00 mg L-1. Therefore, the most effective model to reduce the lead content was flowing water treatment within 24h in the freshwater soft body snail and 18h in the water sample.

Abstract

The spawning sites of Anguilla borneensis and Anguilla celebesensis were in the seas off Sulawesi and the Gulf of Tomini, the spawning sites of Anguilla marmorata and Anguilla bicolor pacifica were in the western part of the North Pacific. The purpose of this study was to find out information on the diversity of eel seeds and adult eels in the Dumoga River based on the abundance of eel seeds and gonad maturity of adult eels. The eel species consisted of 1,106 A. marmorata, A. bic. pacifica as many as 854 tails and Anguilla spp as many as 291 individuals. The caught eel fish were separated based on the morphology of the eel species. Segregation of catches based on special characteristics of eel, namely preanal and predorsal lengths. Anodorsal values were divided into three groups, namely ±15.57% (A. marmorata); ±1.18% (A. bicolor pacifica) and ±7.09% (Anguilla spp.). Meristic values of A. marmorata for spine (TB) total 104-106 units, pre-dorsal TB 17-19, pre-anal TB 36-39 and ano-dorsal TB 18-20. Meristic values of A. bicolor pacifica for spine (TB) totaled 108-112, pre-dorsal TB 32-36, pre-anal TB 32-39 and ano-dorsal TB 0-3. Meristic values of Anguilla spp for spinal (TB) totaled 100-106, pre-dorsal TB 27-29, pre-anal TB 30-33 and ano-dorsal TB 6-12. The growth pattern of adult eels is negative allometric, i.e. the body length gains faster than the slower body weight gain. The condition of adult eels in the Dumoga River is not fat because the condition factor ranges from 0.0024-0.0036. The average length of adult eels was 58.92cm in Anguilla marmorata (GIC 1.57–2.90%); 54.2cm in A. bicolor pacifica (ICI 1.27–2.79%) and 52.32cm in Anguilla spp (ICI 0.97-2.50%).

Abstract

Pasuruan Regency is a major industrial center in Indonesia where their heavy metal industrial waste accompanied by  , household waste, and agricultural activities polluted  Pasuruan waters. The purpose of this study was to determine the status of heavy metal pollution in the Pasuruan sea in the coastal areas of Kraton, Lekok and Nguling and to find out how to overcome it. The survey method was used in this study to analyze the levels of heavy metals (Hg, Pb, Cd) in the waters and calculate the water pollution status based on the pollution index and water quality. Water sampling is carried out at a depth of between 2-15 meters at 3 stationary lift nets (Bagan tancap) at each location. The results showed that the highest levels of heavy metals were found in Lekok waters. The results of the calculation of the pollution index (IP) show that Lekok water has a heavy pollution status for all types of heavy metals (Hg, Pb, Cd). The pollution status in Nguling and Kraton waters based on the Hg and Cd pollution index is classified as heavily polluted. Meanwhile, heavy metal levels of Pb still meet water quality standards. The results of measurements of temperature, pH, dissolved oxygen, salinity, and current velocity are classified as optimum for aquatic biota. Based on the research results, it is known that there are areas of Pasuruan waters that are heavily polluted. Therefore, better water quality management is needed to meet the needs of biota by planting Rizhophora mucronata mangroves.

Abstract

Microalgae as a source of nutrients, can be a good alternative to the use of high-level organisms. The abundant omega 3 content in plankton, especially phytoplankton, needs to be conducted research on the identification of the types of phytoplankton in milkfish with high omega-3 quality. The purpose of the study was to identify the types of plankton containing omega-3 and to determine the levels of omega-3 from plankton found in milkfish ponds. This research was conducted at the Laboratory of the Faculty of Fisheries and Marine Sciences, Brawijaya University, Malang. The highest abundance of phytoplankton is from the Bachillariophyta division and the lowest division euglenophyta. Five types of plankton were determined to be tested for omega-3 fatty acids using the gas chromatography (GCMS) method, namely: Chaetoceros sp, Tetraselmis sp, Nitzchia, Chlorella and Spirulina. GCMS test results from several types of omega-3 fatty acid plankton isolates in Chaetoceros calcitrans were the highest compared to the other 4 plankton types. Conclusion of the composition of plankton in traditional pond waters consists of 4 phytoplankton divisions namely Chlorophyta, Chrysophyta, Cyanophyta, and Euglenophyta. GCMS test results from several types of plankton isolates omega-3 fatty acids in Chaetoceros sp, the highest compared to Tetraselmis sp, Nitzchia, Chlorella and Spirulina. Suggestion of natural feed in the water of milkfish ponds should use Chaetoceros sp because the content of omega 3 is high. Keywords: phytoplankton, omega-3

Abstract

Waters that are presumably contaminated with heavy metals need to be observed to ensure the level of pollution to perform water restoration. This study was aimed to determine the status of water quality based on heavy metal contents. The survey method was employed in this study, and it was conducted in Pasuruan sea waters in different seasons; September 2019 represented the dry season, and April 2020 represented the rainy season. The water sampling stations were chosen by using purposive sampling in three sampling locations: the sea waters of Kraton, Lekok, and Nguling districts. The heavy metals and water quality parameters were analyzed by using Storet Index. The results indicated that the highest level of heavy metals was found in Lekok waters in September, consisting of Hg (1.22 mg/l), Cd (1.20 mg/l), and Pb (0.55 mg / l). The seawater of Nguling district had the lowest content in April, while Kraton's seawater was moderate. The water quality status based on the Storet Index suggested that the sea waters of Kraton, Lekok, and Nguling districts were classified as moderately polluted with a score of -16 to -24. The highest score was in September in the rainy season with a score of -24 and the score in April in the dry season was -16. It means that the score is increasing but still in the moderately polluted category. The measurement results of temperature, pH, dissolved oxygen, salinity, and current velocity were in optimum results for aquatic organisms in the dry season or the rainy season. Regarding the water quality status in Pasuruan sea waters, it can be concluded that the heavy metal contents exceeded the quality standard set by the government. Therefore, improved management is required to prevent the deterioration of the pollution status in Pasuruan sea waters

Abstract

Produksi limbah Industri dan juga buangan limbah rumah tangga yang semakin meningkat dan terjadi terus-menerus, menjadikan sungai tempat pembuangan terakhir sehingga dapat mencemari biota yang berada disekitaran sungai tersebut. Masyarakat di Desa Kupang memanfaatkan aliran sungai tersebut sebagai sumber air untuk budidaya rumput laut Gracilaria sp. Salah satu untuk mengetahui cemaran logam berat pada perairan tersebut dengan mengecek keberadaan kadar Metallothionein pada rumput laut, karena sifat Metallothionein adalah protein yang dapat mengikat logam esensial maupun non esensial. Penelitian ini bertujuan untuk mengetahui kadar Metallothionein pada Gracilaria sp. yang terekspresi pada bagian pangkal dan ujung rumput laut Gracilaria sp. Metode yang digunakan adalah metode deskriptif. Analisis pengujian kadar Metallothionein menggunakan Eliza rider. Hasil penelitian ini bahwa kondisi perairan budidaya tambak Gracilaria sp. untuk parameter suhu, pH, DO sesuai dengan kondisi perairan tambak, tetapi pada parameter salinitas tidak sesuai yaitu melebihi SNI 40 ppt, karena penguapan yang tinggi pada saat musim kemarau, sehingga kadar garamnya tinggi. Kualitas perairan sangat berpengaruh dengan keberadaan Enzim Metallothionein pada pangkal dan ujung rumput laut, Kadar enzim Metallothionein tertinggi terdapat pada bagian ujung Gracilaria sp. yaitu berkisar antara 2.026-2.734 mg/mL. Terjadinya penyerapan yang tinggi karena pada bagian ujung terdapat banyak percabangan kecil dan masih muda sehingga proses penyerapannya masih kuat, sedangkan pada bagian pangkal terdiri dari sel-sel yang sudah tua dengan percabangan yang sedikit dan jumlahnya juga sedikit.
