“…The value of the degree of acidity (pH) shows the acidity or alkalinity of the water (Salim, 2021). Changes in pH affect the growth of microorganisms because most microorganisms cannot tolerate pH levels < 4.0 or pH > 9.5 (Al Kholif et al, 2020). pH value in the FWSCW system is expected to be neutral or close to neutral because, in that condition, the oxygen requirement and production in the plant's root zone for photosynthesis, respiration, and decomposition processes can be optimum.…”

Brantas River is a raw clean water sources that flow through Malang City. The Brantas River water is polluted due to discharging of untreated wastewater, causing a decrease in river water quality. According to these problems, exploring water resources through Brantas River water treatment is essential using Free Water Surface Constructed Wetland (FWSCW) which aims to analyze the performance and improve the water quality of the Brantas River using these wetlands. The research was conducted on a laboratory scale with control treatment and FWSCW with aquatic plants such as Pistia stratiotes, Echinodorus palaefolius, and Heliconia psittacorum. The results showed that pH and temperature were stable, with values between 7.63 to 8.53 and 23°C to 27°C. The removal efficiency of FWSCW and control in reducing turbidity was 99.53% and 98.55%, respectively, and TDS reduction was 0.56% and 2.84%, respectively, for control and FWSCW. The water quality has met the 2nd class of the water quality standards based on Government Regulation of the Republic of Indonesia No. 82 of 2001. At the same time, the efficiency of reducing BOD concentration was 89%. The results show that the FWSCW system can be used as a secondary treatment system to produce clean water.

The effluent of tofu’s anaerobic digester contains organic matter and require further treatment. Constructed wetland (CW) using forage grass plant is one of the alternatives. The study is aimed to observe the effect of CW’s stage variation and planting duration on TSS and COD effluent. Plant growth also observed duringoperation. Two CWs horizontal subsurface tank of dimension 100 cm x 50 cm x 50 cm were arranged in series as stage 1 and 2. Tank was planted with Pennisetum purpureum c.v Mott at spacing of 25 cm, tank without plants as control, and operated at hydraulic loading rate of 0.1 m3/m2.day. Temperature, pH and plant height was measured every 2 days, TSS and COD every 1-2 week. The study showed, there was relatively no temperature difference between control and planted CW. The pH effluent increased with the pH of stage II being higher than stage IThe TSS and COD removal efficiency in planted CW was 61-90 % and 27-85 %, while for control was 8-85 % and 13-79 %, respectively. Plant can grow, indicated by the addition of plant height and plant weight during harvesting. In conclusion, CW stage and planting duration had effect on TSS and COD effluent.

Cyanide is one of the toxic materials in the environment and is included as a hazardous waste. One agro-industrial wastewater containing cyanide is from tapioca industry. Various methods, including constructed wetlands, can reduce cyanide compounds in wastewater. Some plants used in wetlands technology include Pistia stratiotes and C. zizanioides, L. This study aimed to analyse the effect of Pistia stratiotes and C. zizanioides, L and media height on cyanide reduction for 15 days. The highest cyanide reduction rate was in the treatment of Pistia stratiotes and C. zizanioides, L with a media ratio of 1:1 and a cyanide concentration of 1 mg/L and in vetiver grass plants with a media ratio of 1:1, 3:1 and 1:3 with cyanide concentration 1 mg/L was 0.1698 mg/L while the lowest rate of cyanide reduction was in the treatment of Pistia stratiotes and vetiver grass and a cyanide concentration of 0.2 mg/L was 0.0627 mg/L.
