Abstract

Nowadays, in the Danau Bangkau swamp, there is a tendency that some types of fish are increasingly difficult to find and the size of the fish that are still available is relatively small, and the catch of fishermen has decreased. Utilization of fishery potential of Danau Bangkau swamp through the development of aquaculture business is an alternative option that must be implemented. This research was conducted to be able to see the feasibility of the water quality in the Danau Bangkau swamp so that hope it can be basic information for the development of aquaculture in that area. The results showed that the temperature range in the waters of the Danau Bangkau swamp was 28.3-32.4 oC, the brightness was 72-95 cm, degree of acidity (pH) is 6.01-7.2, dissolved oxygen (DO) 1.2-4.3 mg/l, nitrate 0.7-9.8 mg/l, phosphate 0.2-3.31 mg/l and total suspended solids 7-48 mg/l. In general, the value of water quality parameters fulfill the quality standards, except for dissolved oxygen and phosphate parameters. The low levels of dissolved oxygen and high levels of phosphate indicated that there has been pollution in the Danau Bangkau swamp waters so it is not suitable for the cultivation activities.

Abstract

The fish diversity in Barito River is determined by diversity of zooplankton, in relation to the grazing food chain’s concept. One of the problems that occur is the quality of several key parameters in waters are no longer suitable for zooplankton and fish life. The purpose of this research were: (a) analyze the key parameters of water quality at the sampling location (b) determine the relationship between key water quality parameters and zooplankton diversity at the Barito River sampling location. The method used was a purposive sampling survey method and the shanon-wiener method. The results showed that the key parameters that met the PP No. 22/2021 Water Quality Standard for Class 2 River Water Quality.

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.
