One of the industrial activities that produces a lot of liquid waste is the tofu industry. Most of the liquid waste from industry flows directly into the sewer without prior treatment. This research aimed to determine the best plant biomass for reducing contaminants in tofu liquid waste. This research used an experimental method with a completely randomized design with 4 treatments and 3 replications, namely A (without addition of Azolla), B (addition of Azolla 250 grams), C (addition of Azolla 3000 grams), and D (addition of Azolla 350 grams). Tofu waste samples were obtained from the Cheese Tofu Factory located in the Cibuntu Tofu Industrial Center, Bandung City. The results of research for 15 days showed that the addition of Azolla microphylla could reduce the levels of contaminants in tofu liquid waste. The addition of 300 grams of Azolla microphylla plants to the phytoremediation process provided the best reduction in contaminants in tofu liquid waste by reducing BOD concentrations by 61%, nitrate by 77.49%, and phosphate by 68.44%.Keywords: Azolla microphylla, phytoremediation, tofu industry.

Kepulauan seribu archipelago is home to Kelapa Dua Island, a potential marine tourism destination and habitat for diverse marine life. The survival of marine biota hinges on suitable physical and chemical water parameters, encompassing temperature, pH, salinity, and dissolved oxygen (DO). This study aims to evaluate water quality and litter distribution on Kelapa Dua Island within Kepualauan Seribu National Park. Results reveal that the water quality largely aligns with established standards; however, specific points surpass limits, notably lower salinity at stasion 3 (26%o), and higher pH at station 2 (9.35). Despite meeting quality standards, the island's status as a populated area and tourist destination raises concerns about potential alterations to water quality. Furthermore, observations on litter distribution indicate a status categorized as B (0-4/m) and C (4-10/m), highlighting a relatively low level of litter presence. The interaction of human activities, both as inhabitants and visitors, may contribute to fluctuations in water quality. Understanding these dynamics is crucial for sustainable management, ensuring the preservation of Pulau Kelapa's ecological integrity as a cherished marine environment and tourist attraction. This study provides insights into the delicate balance between human interactions and environmental preservation in the context of Pulau Kelapa, Kepualauan Seribu.Keywords:Water qualityLitter DistributionKelapa Dua IslandKepulauan Seribu

This study aimed to evaluate the effectiveness of an aquarium-based Integrated Multi-Trophic Aquaculture (IMTA) system compared to a monoculture system. The research was conducted from November to December 2024 at the Aquaculture Laboratory, Faculty of Fisheries and Marine Sciences, Universitas Padjadjaran. The experimental design used was a Completely Randomized Design (CRD) with five treatments and three replications, involving combinations of guppy fish (Poecilia reticulata), Egeria densa aquatic plants, Ramshorn snails (Planorbella duryi), and Orange Rili shrimp (Neocaridina davidi). Parameters observed included water quality (pH, DO, nitrate, phosphate, turbidity, temperature), organism growth, benefit-cost ratio (BCR), and aesthetic value using a 1–5 scale. The results showed that Treatment E (combining fish, plants, snails, and shrimp) provided the best performance, with the most stable water quality, highest organism growth, highest BCR, and an average aesthetic score of 4.89. The IMTA system was shown to improve resource efficiency, reduce biological waste, and enhance the visual appeal of aquarium-based aquaculture. These findings support the application of aquarium-scale IMTA as a sustainable aquaculture model that is ecologically, economically, and aesthetically adaptive.

The problems of shrimp farming with semi-intensive systems are leftover feed, organic matter, and toxic compounds that can reduce water quality. Shrimp pond wastewater treatment can be done through several technologies, such as chemical, physical, and biological treatment. One of biological treatment that widely used for wastewater treatment is bioremediation. Bioremediation is a biological process that utilizes microorganisms to decompose waste in aquaculture ponds into compounds that are not harmful to aquatic biota. Therefore, this researchaims to determine the effect of effective microorganism-4 (EM4) in reducing ammonia compounds and BOD levels in shrimp pond wastewater. The research method used is a laboratory-scale experimental method. A total of6aquariums were used for 3 different treatments with two replications, control, adding EM4 2.5% and EM4 3% into 5 L of wastewater. Thewater quality parameters observed were dissolved oxygen, temperature, pH, ammonia, and BOD. Theone-wayANOVA test was used in this study. The results showed that there was a decrease in ammonia and BOD levels. The highest reduction of ammonia was found in the treatment with the addition of EM4 2.5%.The decrease in BOD with the highest effectiveness was found in the control treatment (37.73%)with the initial BOD value 5.3to3.3. mg/l, which fulfilled the allowed maximum level ofstandard of Ministerial Decree No. KKP. KEP.28/MEN/2004 concerning General Guidelines for Shrimp Cultivation in Ponds. In conclusion, the small dosage addition of EM4 did not have a significant effect on decreasing levels of ammonia and BOD.

Cisanti Lake, the strategic zero point of the Citarum River, faces the threat of cadmium (Cd) pollution from surrounding agricultural activities. Conducted during the dry season of 2024, this pioneering study assesses the Cd pollution status using a multicompartment approach (water, sediment, and bioindicator organism Sinanodonta pacifica, Heude 1878). Samples from the three stations were analyzed using Atomic Absorption Spectrophotometry (AAS). The concentration of Cd in water was very low (0.0012–0.0030 mg/L), but it accumulated significantly in sediment (0.37–0.65 mg/kg) and mussel tissue (0.20–0.30 mg/kg). Although the concentration in water and biota was below quality standards, ecological risk analysis revealed that the sediment has moderate contamination (Contamination Factor: 1.25–2.15) and acts as a long-term pollutant sink. S. pacifica proved effective in accumulating Cd from the water column, demonstrated by a high Bioconcentration Factor from water to biota (BCF b-w >75), making it a reliable bioindicator of Cd pollution. This study provides crucial baseline data on environmental management in the upstream Citarum and establishes sediment monitoring as a vital early warning tool for future pollution risks.
