Abstract A coagulant is a chemical needed by water to help settle small particles that cannot settle on their own. Meanwhile, total suspended solids (TSS) result from filter dissolved solids by gravity deposition, usually in chloride particles, and indicate the sedimentation rate. This study aimed to determine the effectiveness of bio coagulants to reduce levels of total suspended solids (TSS) in liquid tofu waste to find out which one is more effective as a bio coagulant in liquid tofu waste. This research is experimental, consisting of 2 stages: the manufacture of charcoal from bio coagulants and the measurement of total suspended solids (TSS) levels. The data collected were tabulated and then analyzed descriptively. Three types of bio coagulants used were tamarind seeds, coffee husks, and cocoa pods. The results showed that there was a decrease in the TSS value before and after coagulation was given. The highest TSS reduction was obtained from bio coagulant charcoal from cocoa pods which reached 54.28% for a coagulant dose of 2 mg/l, while for a coagulant dose of 5 mg/l it could reduce TSS by 70.71%. It means the cocoa pods waste have a potential to use as coagulant to control sedimentation in the environment.

Waste of heavy metal lead (Pb) in waters needs to be addressed through phytoremediation because it is toxic to the environment. The purpose of this study is to determine the effect of water hyacinth (Eichhornia crassipes) ability in water to absorb heavy metal Pb and its effects to total dissolved solids (TDS) of groundwater during the phytoremediation process. Using E. crassipes, groundwater samples and Pb(NO3)2 as a source of Pb, the initial characterization of the two samples was previously carried out. Created four treatments of ground water, i.e.:  P1 contains 2 ppm Pb with E. crassipes, P2 contains 4 ppm Pb with E. crassipes, P3 contains 2 ppm Pb without E. crassipes, and P4 contains 4 ppm Pb without E. crassipes. Observation of Pb by method of atomic absorption spectrometry (AAS) and determination of TDS by gravimetric method, each carried out on days 0, 4, 8, and 12. The results show the treatment of 2 ppm Pb, E. crassipes is more effective at absorbing Pb which is 96.0% compared to treatment 4 ppm Pb which is 90.0%. While 2 ppm Pb and 4 ppm Pb as control only 18.5% and 17.5%. Treatment of 2 ppm Pb which uses E. crassipes shows better water quality than concentration TDS 62.55 ppm compared to treatment of 4 ppm Pb with TDS 70.50 ppm while 2 ppm Pb and 4 ppm Pb as a control does not significantly affect to water quality.

Water hyacinth (Eichhornia crassipes) is a plant species commonly used for phytoremediation to reduce high chromium content in tannery liquid waste in Garut, West Java. Water hyacinth materials harvested from the phytoremediation can be used for the anaerobic digestion process to produce biogas and bio-slurry. This study aimed to determine the reduction of chromium content found in water hyacinths due to the anaerobic digestion process, and utilization of bio-slurry from the anaerobic digestion process as a biocomposite material. The anaerobic digestion process was carried out for 33 d using biodigesters and the composition of the biodigesters were varied into 100% dried water hyacinths and 80% water hyacinths with the addition of 20% cow dung. The bio-slurry from the anaerobic digestion process was then used for making biocomposites with 3 different compositions, i.e., 75 and 25%; 50 and 50%; and 25 and 75% of cement and bio-slurry, respectively. The average chromium content found in water hyacinths from the phytoremediation process without anaerobic digestion process was 41.964 mg/l. The results show a reduction in the amount of chromium after the anaerobic digestion process was found in each composition of bio-slurry, which were 15.979 mg/l (100% water hyacinth) and 14.861 mg/l (80% water hyacinth + 20% cow dung). Biodigester with a composition of 80% water hyacinth + 20% cow dung produced the highest average volume of biogas which was 0.424 l. The biocomposite of 75% cement and 25% bio-slurry had the highest compressive strength value of 30.598 MPa and water absorption capacity of 37.25%. It can be concluded that biocomposite with the composition of 75% cement and 25% water hyacinth bio-slurry is promising to be used as an alternative material for buildings.

Abstract The current development of aquaculture raises problems in the form of pollution of liquid waste generated during the production process. Aquaculture wastewater contains very high concentrations of inorganic nutrient. This study aims to determine the effectiveness of Sargassum polycystum density as a biofilter to reduce nitrate and phosphate in whiteleg shrimp pond. The study was conducted experimentally at indoor tank culture using a Completely Randomized Design (CRD) consisting of 3 density treatments with 3 replications, which were 1 gL−1, 2 gL−1, and 3 gL−1. The parameters observed were water quality such as nitrate, phosphate, temperature, salinity, pH, DO (Dissolved Oxygen), TSS (Total Suspended Solid), and TDS (Total Dissolved Solid); and also Saragassum’s growth. The results showed that the density of 3 gL−1 able to reduce nitrate 80% and phosphate 86,30%. The growth of S. polycystum for the three treatments decreased due to several factors, such as low nitrogen availability, environmental conditions, predators, and differences in stocking density. The average water quality measured during the study was temperature 27.84 °C; salinity 31.31 ppt; DO 4.72 mgL−1; pH 7.69; TDS 34.94 mgL−1; and TSS 4807.63 mgL−1. S. polycystum has the ability as biofilter for white shrimp culture because able to reduce nitrate and phosphate concentration. S. polycystum has potential benefits as alternative comodity candidate for polyculture and Integrated Multi Throphic Aquaculture (IMTA).
