Abstract

The tidal dynamics of water affect not only the layers on the surface of the seas but also the entire water mass. The Tabanio River is a tidal-influenced water area with the highest utilisation level in Tanah Laut. Water quality at the estuaries of Tabanio and Panjaratan River is affected by various human activities, such as fishing, plantations, transportation, and waste disposal. This study aims to compare water quality at high and low tides and test the relationship between tidal changes and fluctuations in water quality parameters in both locations. The data used are the results of measurements on July 3 and July 22, 2024, during high and low tide conditions. The relationship between water quality values and tides was analyzed descriptively, then compared with water quality standards according to Government Regulation of the Republic of Indonesia Number 22 of 2021 class 1 and continued with the ANOVA test. Low tide conditions bring to increase in the parameters of conductivity, current, temperature, pH, salinity, and TDS at all locations, while turbidity is only in the estuary. Tidal conditions influence oxygen deficits in all sites, while nitrite and nitrate tend to increase. TSS parameters exceed quality standards in Panjaratan, while Cu and COD exceed quality standards in Tabanio.

Abstract

Situ Cilodong is located in Kalibaru, Cilodong, Depok. Situ Cilodong served as a beautiful, strategic area and thus served as a local water tourism. However, the presence of a human activity causes it to contain household wastes and other fillings that leak into the body of the water. The study was intended to determine the quality of the water and was held by storet methods. Storets method work by comparing data on water quality with water quality adjusted to it in order to determine water quality status. The parameters used in this study are the physical parameters in the form of temperature and brightness, also chemical in the form of pH and DO, all parameters was measure insitu in the morning. We also do identyfication of plankton. Data retrieval times occurred periodically each week of November 2021. Based on its designation, Situ Cilodong is included in class 2. The sampling station point being used is at the inlet station, center and outlet. The result of research is that the waters at Situ Cilodong was classified as a light polluted lake based on stroret's methods score on the inlet -10 station, -8 and -10 outlets. The most frequently identified type of planton species is from the phytoplanton group.
