Abstract

This article presents a comprehensive literature review on the impact of physical of ponds on the growth and survival of dumbo catfish (Clarias gariepinus). By analyzing various studies and scientific articles, this research summarizes information on the optimal range as well as the negative effects of temperature, pH, turbidity, and dissolved oxygen (DO) levels on the physiology and growth performance of dumbo catfish. The sources studied consistently emphasized the importance of maintaining the stability of physical variables within the limits acceptable to this species to improve efficiency in aquaculture. The synthesis also points out knowledge gaps and areas of research needed to better understand the complex interactions between the physical variables of pond waters and the biological reactions of dumbo catfish. The conclusion of this review emphasizes that proper management of the physical variables of pond waters is a key factor for success and sustainability in dumbo catfish aquaculture.

Abstract

Estuary waters are transitional ecosystems between marine and terrestrial environments that are highly productive but vulnerable to environmental degradation. productive but vulnerable to environmental damage, especially due to nutrient pollution from human activities. Literature studies in the last five years the last five years have shown that key nutrient elements such as nitrate, phosphate and ammonium play an important role in estuary ecosystem dynamics. High concentrations of nitrate and phosphate concentrations are associated with an increase in phytoplankton, but can also lead to potential eutrophication. can lead to potential eutrophication, Changes in currents due to nutrient inputs affect the composition of the plankton community in the estuary, river flows carry high nutrient loads from the land which accelerates the eutrophication process as well as changes in the trophic status of the waters. changes in the trophic status of the waters. This article aims to assess the influence of nutrients on estuary waters based on a literature review, and provide recommendations for sustainable ecosystem-based management.

Abstract

In a democratic system, every individual has the right to voice their opinions and ideas, which become the foundation for the formation of public policies that are fair and in favor of the common interest. However, this right is also accompanied by the obligation to actively participate in democratic processes, whether in elections, public discussion forums, or in running the government. Democracy is not only about freedom of speech, but also about active contribution in determining the direction of the nation. This article examines the relationship between individual and collective rights and obligations in realizing quality democracy, as well as the challenges faced by society in implementing both. This discussion aims to strengthen the understanding that democracy is achieved when every citizen not only knows his or her true rights, but also carries out his or her obligation to participate in the political process constructively.
