Abstract

Abstract Civic Education (PKn) plays a crucial role in shaping the nation's character, especially in facing the challenges and opportunities presented by the digital era. PKn aims to equip students with an understanding of their rights and duties as citizens, as well as instill national values based on Pancasila and the 1945 Constitution. In the digital era, technological advancements provide easier access to information but also pose a challenge in preserving national values often eroded by the global information flow. Therefore, civic education must be adjusted to technological developments, accompanied by the enhancement of critical thinking and empathy skills. Technology-based learning strategies, such as the use of digital media and social platforms, can make the learning process more engaging and relevant to the younger generation. This study aims to examine the role of PKn in building the nation's character in the digital age and strategies that can be implemented to optimize PKn learning.

Abstract

  Water quality management in public waters is a crucial aspect of maintaining ecosystem balance and the sustainability of aquatic resources. This study examines key water quality parameters such as temperature, pH, dissolved oxygen, and organic matter content, as well as their impact on aquatic life. Data were collected through field surveys and laboratory analyses at various public water locations. Results indicated significant variations in water quality, largely influenced by anthropogenic activities such as agriculture and industry. The study recommends sustainable management strategies to preserve water quality and support aquatic ecosystem conservation.

Abstract

Estuaries are transitional ecosystems between freshwater and marine environments, characterized by high productivity and complex biodiversity. This study aims to analyze the physical, chemical, and biological characteristics of estuarine ecosystems and identify the impact of anthropogenic activities on environmental quality and community structure. A descriptive quantitative method was applied through field observations and laboratory analysis across three estuarine zones (upstream, middle, and downstream). The results show environmental gradients, with increasing salinity and nutrient levels from upstream to downstream. Communities of phytoplankton, zooplankton, macrozoobenthos, and fish displayed distribution patterns influenced by local environmental conditions. Decreasing dissolved oxygen and rising nitrate and phosphate concentrations indicate anthropogenic pressures that may degrade ecosystem quality. Therefore, sustainable estuarine management is necessary to maintain ecological balance and ecosystem services.
