Abstract

Mercury is used as a gold binder and released into the aquatic environment that causes pollution. The concentration of mercury in gold washing wastes must be minimized so that it is not harmful to the waters. One way is to precipitate waste. This study aims to detect mercury concentrations and water quality in each reservoir pool before waste is discharged into the water. The waste pool is six pools (P1, P2, P3, P4, P5, P6) with one pool of clean water (P0). Mercury was detected using Atomic Absorption Spectrophotometry (AAS), the water quality measured was temperature, pH, and color of wastewater. The research data were analyzed descriptively. The concentration of mercury in all settling ponds was between 0.021 ± 0.002 mg / L to 0.051 ± 0.005 mg / L). The decrease in the average mercury concentration from pond P1 to P6 is 16.7%. The concentration of mercury has exceeded the maximum allowed for mercury in water. The temperature in each pond has decreased from pond P1 to P6, but pH has increased.

Abstract

Plankton merupakan salah satu jenis pakan alami yang berperan penting untuk pertumbuhan organisme akuatik terutama ikan. Tujuan dari penelitian ini adalah untuk mengetahui jenis-jenis plankton beserta kelimpahannya di perairan dan di lambung ikan nila yang tertangkap di Waduk Wonorejo, beserta aktivitas enzimatis lambung ikan nila tersebut. Penelitian ini bertempat di Waduk Wonorejo, Tulungagung, Jawa Timur dengan metode survei. Sampel diambil dari 2 stasiun, yaitu stasiun pertama di daerah wisata Waduk Wonorejo, sedangkan stasiun 2 berada di wilayah pemancingan umum Waduk Wonorejo. Plankton di perairan Waduk Wonorejo ditemukan 17 genus fitoplankton, dan 5 genus zooplankton, sedangkan di lambung ikan nila ditemukan 30 genus fitoplankton dan 2 genus zooplankton. Genus Spirogyra sp. merupakan genus yang paling tinggi kehadirannya baik di lambung maupun perairan Waduk Wonorejo. Kelimpahan plankton di perairan waduk dapat digolongkan oligotrofik dengan nilai kelimpahan plankton sebesar 1487 ind/ml di stasiun 1 dengan keanekaragaman tinggi dan 746 ind/ml di stasiun 2 dengan keanekaragaman sedang, serta tidak ada jenis plankton tertentu yang mendominasi di kedua stasiun tersebut. Analisis aktivitas enzim lambung ikan nila menunjukkan aktivitas enzim protease sebesar 0,84 ± 0,02 µmol tirosin/g enzim menit; enzim amilase 14,59 ± 1,07 µmol glukosa/g enzim menit; enzim lipase 17,83 ± 0,14 µmol asam lemak/g enzim menit. Kualitas air di Waduk Wonorejo tergolong baik dengan suhu berkisar 26,3-27,3 oC, pH 7, DO 7,1-8,4 mg/L, Kecerahan 110-154 cm, TOM 19-30,3 mg/L. Maka dari itu upaya untuk mempertahankan kondisi Waduk Wonorejo agar tetap oligotrofik perlu dilakukan.

Abstract: Daerah muara sebagian besar dimanfaatkan oleh masyarakat pesisir untuk kegiatan budidaya perikanan seperti tambak. Limbah yang dihasilkan oleh tambak langsung dibuang ke sungai tanpa diolah terlebih dahulu. Secara umum petambak tidak menyadari bahwa limbah yang terbuang itu menambah beban organik perairan, apalagi bahan organik tersebut tidak segera terurai menjadi bahan an organik. Pada daerah pesisir ditumbuhi beragam tanaman mangrove tetapi tanaman tersebut tidak dapat manfaatkan bahan organik bahkan bahan organik dapat menghambat pertumbuhannya. Di sisi lain mangrove merupakan ekosistem pesisir yang berguna untuk melindungi pantai, kerusakan mangrove akan berakibat bencana bagi daratan di belakangnya. Maka dari itu perlu adanya upaya untuk menginformasikan masyarakat menegnai cara menurunkan bahan organik dari limbah usaha budidaya agar perairan pesisir tidak tercemar dan tumbuhan dapat tumbuh dengan baik dan sehat sesuai fungsinya. Wilayah pesisir memerlukan perlindungan agar tidak terjadi abrasi atau pengikisan tepain pantai. jika terjadi pengikisan ini maka lama kelamaan pesisir pantai tersebut akan terkikis. Perlindungan pesisir bisa dilakukan dengan menanam mangrove maupun dengan menanam pohon pelindung pantai. maka dari itu, penyuluhan ini diperlukan agar masyarakat di sekitar pesisir pantai. Keywords: Kerang Kijing; mangrove; tambak; limbah, muara

Abstract

Hematological observations of Nile tilapia (Oreochromis niloticus) were carried out in oligotrophic waters (Wonorejo Reservoir) in July-August 2018 and eutrophic waters (Selorejo Reservoir) in March-April 2021. Both reservoirs are located in East Java, Indonesia. The number of fish samples from the Wonorejo Reservoir was 80 fish, while the sample from the Selorejo Reservoir was 108 fish. Sampling was carried out 3 times every 2 weeks. The erythrocyte, hemoglobin, and hematocrit levels of tilapia from Selorejo Reservoir (eutrophic waters) were lower than those from oligotrophic waters. The condition of low levels of erythrocytes, hemoglobin, and hematocrit indicates that fish are under stress. The leukocytes and micronuclei were higher in fish from eutrophic waters which were thought to be less healthy. The hematology of Nile tilapia from the Wonorejo Reservoir (oligotrophic) was in good condition, while the Nile tilapia from the Selorejo Reservoir (eutrophic) was not in good condition, which was thought to be due to the eutrophic condition of the waters there was an imbalance of physico-chemical water, so that the health of the fish was disturbed

Abstract

Wastewater from vaname shrimp culture with a semi biofloc system, was used for milkfish cultivation without additional feed. Fish seeds are stocked 4000 with 18 days of age. The Milkfish pond is 2000 m2, the water level is 0,7 m. Water quality was observed 2 months cultivation. Water samples were taken everyweeks around 9 am, from March to April 2022. During the research, temperature, brightness, pH, dissolved oxygen, CO2 and salinity were relatively stable, except for nitrate and phosphate levels. First observation the levels of nitrate were 0,059 mg/l and phosphate was 0,064 mg/l. When the fish were 2,5 months, nitrate levels increased by 425,4% to 0,31 mg/l and phosphate increased by 479,7% to 0,371 mg/l. This increase is thought the addition of residual water from vannamei shrimp cultivation, so that the pond water level becomes 80 cm. Observation of milkfish at the age of 3 months, nitrate levels decreased 42,6% to 0,178 mg/l and phosphate decreased 8,4% to 0,34 mg/l. This decreasing is thought because nitrate and phosphate are used as a source of nutrients for phytoplankton. The milkfish are 3,5 months, the nitrate level decreases by 58,4% to 0,074 mg/l, but the phosphate level increases by 8,24% to 0,368 mg/l. The increase in phosphate is thought to be from the decomposition of fish feces. And the decreasing of nitrate because used as a source of nutrients for phytoplankton. Water quality monitoring must be carried out regularly, to preserve pond water quality.

Abstract

Vannamei shrimp (Litopenaeus vannamei) is one of the leading commodities in Indonesian aquaculture. The cultivation potential that is developing at this time is with intensive technology. However, along with the development of intensive technology, it experienced problems, namely crop failure caused by a decrease in water quality. This study aims to examine the physical and chemical dynamics of vannamei shrimp pond water cultivated with a semi-biofloc system. This study used a survey method and was statistically analyzed using Ms. Excel and Principal component analysis (PCA). Physical and chemical parameters of water that are measured and observed include Temperature, Brightness, pH, Dissolved Oxygen, Salinity, Carbon Dioxide (CO2), Total Organic Matter, Nitrate (NO3), Phosphate (PO4-) and Ammonia (NH3). The results showed that all the physical and chemical parameters of pond water experienced daily and weekly fluctuations during shrimp rearing. Average temperature fluctuations during the study ranged from 26.7 – 32.5 oC, brightness ranged from 26.5 – 85.0 cm, pH ranged from 7 – 8 tended to be normal, dissolved oxygen ranged from 5.8 – 8.8 mg/L, salinity ranged from 18.3 – 22.8, carbon dioxide (CO2) average values during rearing were 0 mg/L, TOM ranged from 18.42 – 71.80 mg/l, nitrate 0.022 – 0.136 mg/l, phosphate 0.017 – 0.136 mg/L and ammonia ranging from 0.008 – 0.088 mg/l. While, the results of the PCA analysis show that dissolved oxygen and brightness significantly affect the life of the shrimp that are cultivated. So it can be concluded that the dynamics of the physics-chemistry of water measured during the study showed that dissolved oxygen and brightness fluctuated and affected aquaculture activities.

Abstract

Insecticides with the active ingredient methomyl are a class of pesticides used to protect agricultural crops from attack by pests such as insects. The areas that used this insecticide were from the results of previous studies, namely the Musi Rawas Paddy Field Center in South Sumatra and Ngantru District, Tulungagung Regency. However, it is possible that many other areas use it. This study aims to prove that the insecticide with the active ingredient metomyl interferes with the growth and survival of the Jatiumbulan tilapia strain (O. niloticus). The treatment consisted of a control and three exposure concentrations namely 1.8, 4.015 and 6.2 mg/L with 3 repetitions each. Exposure was carried out artificially once in rearing water and observations were made for 4 days (96 hours). In conclusion, the results showed that as the exposure concentration of the insecticide with the active ingredient metomil (Lannate with 25 % methomyl) increased, the stress occurred faster which resulted in decreased growth, survival, time of death, and clinical symptoms. However, the concentration of 6.2 mg/L (treatment C) gave significantly different results in survival parameters compared to the 1.8 and 4.015 mg/L treatment. This is because in treatment C there was stress to death and this condition did not occur in treatment A and B

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.
