Communal wastewater treatment plant (CWWTP) has been chosen as one system to treat domestic wastewater due to simple technology, flexible management, and cost-effectiveness. There are 376 CWWTP have been recorded by Environmental Agency of Yogyakarta (DLH DIY) that spread in five regencies. Monitoring results on CWWTP effluent showed that some physical and chemical parameters did not meet the domestic wastewater standard. Therefore, evaluation of removal efficiency in terms physical and chemical parameters are necessary. The samples were collected from nine CWWTP in Banguntapan, Bantul and Gamping sub-districts. The physical and chemicals parameters (pH, TSS, BOD, COD, Ammonia, oil, and grease) of influent and effluent from CWWTP are analyzed based on National Standard of Indonesia (SNI) for domestic wastewater. The results show that BOD (>70%) and TSS (>50%) have better removal effectiveness compare with COD, ammonia, oil, and grease (40%). Overall, CWWTP in Banguntapan subdistrict has better performance compare with CWWTP in Bantul subdistrict.

Sea cucumbers are an essential fishery resource. Therefore, effective aquaculture methods should be developed to achieve their optimal production. Sea cucumbers are susceptible to various environmental factors, one of which is water quality. Monitoring water quality based on physical and chemical parameters should be useful to the rearing system in aquaculture. In practical use, farmers usually monitor only temperature, salinity, and pH, neglecting the essential role of chemical parameters. This review focuses on and urges the monitoring of physical and chemical parameters. We explored the water quality parameters that may be crucial to the sea cucumber rearing system, including temperature, salinity, pH, dissolved oxygen, ammonia, turbidity, particulate organic matter, total nitrogen, nitrate, nitrite, ammonium, silicate, and phosphate. Furthermore, this paper presents a practical way to monitor the aquaculture or rearing system of sea cucumbers. It is suggested that temperature and salinity are the crucial physical parameters, while the essential chemical parameters are phosphate, nitrate, and ammonia.

Peat soil is a type of soil that is formed from the accumulation of plant debris which undergoes a decomposition process. This is why peat soil contains high organic matter and is acidic. Peat soils will affect the parameters of a surrounding aquatic ecosystem, such as the Rasau peat swamp ecosystem in the village of Rantau Panjang. Peat swamp water parameters are influenced by substances stored in the peat such as having a low pH, high heavy metal content, and having high TSS, TDS, BOD and COD values. The water parameter of peat swamp with mangrove vegetation is better than that of peat swamp that does not have mangrove vegetation. This can be seen if the peat swamp water parameters are laboratory tested. The physical parameters of water, namely temperature, TDS, DHL, color, and turbidity were lower in the Rasau peat swamp with mangrove vegetation compared to the non-vegetated ones. The chemical parameters of the Rasau peat swamp with high density mangrove vegetation such as higher pH, and lower BOD, COD, and iron (Fe) when compared to peat swamps without mangrove vegetation. However, the physical and chemical parameters of vegetated and non-vegetated peat swamps are still above the PPRI No. 82 of 2001.
