Abstract

Shrimp aquaculture wastewater after the end of the rearing period has a high total organic matter (TOM) content of up to 87.74 mg/L. If the wastewater is disposed of directly without any efforts to reduce or treatment, it will disturb public waters ecosystem because of the high organic matter. The aim of this study was to determine the rate of reduce of organic matter in pond aquaculture waste. The study was carried out in January 2021. Pond wastewater samples were taken from the Tambak at the end of the maintenance period (120 days of maintenance). The trademarks of the bacterial consortium are EM4, Bio HS, BIO Prisma, Starbio plus, BIO2000, and Biolet. The experimental research was arranged in a completely randomized design with 6 treatments and 4 replications. Each treatment was filled with 2 liters of wastewater plus 6 ml of a liquid bacterial consortium. As for the solid bacterial consortium, 1 gram/L was added. Measurements of total organic matter, temperature, pH, dissolved oxygen, salinity and carbon dioxide were carried out every 24 hours for 72 hours of observation. The results showed that during 72 hours of immersion the highest percent reduction in organic matter was in treatment E (BIO 2000) of 95% (87.74 mg/L to 4.11 mg/L). The lowest percentage decrease was in treatment D (Starbio plus) of 83.4% (87.74 mg/L to 14.54 mg/L). However, in general 6 types of bacterial consortium trademarks can degrade organic matter. The levels of temperature, pH, dissolved oxygen and salinity are in optimum conditions, while carbon dioxide exceeds the threshold caused by the high activity of overhauling organic matter by bacteria. The conclusion was obtained that the trademark of the bacterial consortium BIO2000 was the most effective in reducing organic matter for 72 hours.Keyword : Shirmp wastewater, Tambak, Bioremediation, Organic Matter, Microorganis

Abstract

Clarias and Nile tilapia ponds contain high organic matter levels which will be decomposed by bacteria. It also produces carbon dioxide, which can be utilized by phytoplankton for photosynthesis process. This research aimed to compare the types of phytoplankton and zooplankton in Clarias and Nila tilapia ponds for eutrophication and water quality control. The research was conducted in August-September 2020. The water samples were taken using plankton net to become 35 ml from Clarias and Nile tilapia ponds. Analysis of plankton abudance, diversity, Evenness and Dominance Index was carried out in the Laboratorium Hidrobiologi. The analysis result of the average abundance of phytoplankton in the Clarias ponds was 71.026 cell/mL (11 genera), and zooplankton was 93 ind/mL (4 genera). Meanwhile in Nile tilapia ponds was 1.503 cell/mL (9 genera), and zooplankton was 91 ind/mL (1 genus). The average of zooplankton in Nile tilapia pond was higher than in catfish ponds; since Clarias are carnivores while Tilapia are omnivores. The plankton diversity index of catfish pond was average 0.817, while in Nile Tilapia was average 0.553. The evenness ndex of catfish pond was average 0.5, while in Nile Tilapia was average 0,4. The dominance index of catfish pond was average 0.59, while in Nile Tilapia was average 0.77. The conclusion obtained is the type of phytoplankton in Catfish pond consisted of 11 genera (99.62%) and zooplankton of 4 genera (0.38%), while in Nile Tilapia pond the type of phytoplankton consisted of 9 genera (97.85%) and zooplankton of 1 genera (2.15%).

Abstract

Comparison of the length, weight and condition factor of Nila Tilapia (Oreochromis niloticus) was studied on oligotrophic waters (Wonorejo Reservoir) conducted from July to August 2018 and eutrophic waters (Selorejo Reservoir) on February to March 2019. All of the reservoir are in the East Java, Indonesia. The total sample from Wonorejo Reservoir about 79 fish from 3 times sampling (every two weeks), but the fish Sample from Selorejo Reservoir are 35 from 4 times sampling every week. The Nila Tilapia from Wonorejo Reservoir are 15.3 ± 2.5 cm (length) and 74.6 ± 38.6 grams (weight) but fish from Selorejo are 17.8 ± 2.2 cm average length and 114 ± 35 grams for the weight. The condition factor of Nila Tilapia in both reservoirs was relatively the same, with an average value was 1.01. The Nila Tilapia caught from Selorejo Reservoir (eutrophic) is relatively heavier and bigger than in the Wonorejo Reservoir (oligotrophic) even though the hook size is smaller. Fish from the Selorejo Reservoir (eutrophic) is easier to get food so that the average fish is larger.

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

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
