Degradation of fishing grounds in North Waters of Banten Province, Indonesia
Summary
This Indonesian study assessed fishing ground degradation in the northern waters of Banten Province through water quality analysis, fishing intensity surveys, and remote sensing. Degraded coastal water quality — including from plastic pollution — affects the health of fishing grounds and the fish stocks that coastal communities depend on.
The high level of fishing activity with small fishing vessels has resulted in relatively high utilization of marine space in coastal areas, manifesting changes in fishing grounds. Thus, this research aimed to analyze water quality, fishing intensity and to determine the level of degradation of fishing grounds in the northern waters of Banten Province. This research was conducted from June to August 2023 in the northern waters of Banten Province. Data collection was carried out using survey, remote sensing, and interview methods. Water quality data consisting of sea surface temperature, brightness, salinity, light attenuation coefficient, total suspended solids, and chlorophyll-a were analyzed descriptively. Eco-friendly capture fisheries data were taken directly from 120 fishermen and analyzed based on the CCRF criteria. Degradation status was determined by combining weight of water quality conditions and eco-friendly capture fisheries. Based on the research results, the northern waters of Banten Province is in good condition for biota life. Fishing equipment is dominated by eco-friendly fishing gear. Nevertheless, several parts of northern waters in Banten Province have experienced light degradation of fishing areas (18.28%) and the heavy degradation (7.71%). The use of marine space for capture fisheries in the northern waters of Banten Province is relatively high, around 50 units of fishing gear for 1 hectare of water.Keywords:EnvironmentFishing intensityFishing gearSpatial mappingWater quality

Water Pollution Index and Microplastic Ecological Risk in The North Coastal Area of Situbondo
Researchers assessed water quality and microplastic ecological risk across 15 locations along the northern coast of Situbondo, Indonesia, and found mild water pollution throughout the study area. Microplastics were found at all sampling sites, with industrial-adjacent areas and estuaries showing higher ecological risk than natural river locations. The study provides baseline data on the extent of microplastic contamination in an Indonesian coastal region and highlights the need for monitoring near industrial zones.

Researchers assessed microplastic accumulation in marine fish from coastal waters of Baru and Trisik Beaches in Yogyakarta, Indonesia, finding microplastics in fish digestive tracts and surface waters, with river outflow serving as a major dispersal pathway for plastic pollution.
Abundance and Characteristics of Microplastics in Surface Waters of Banten Bay, Serang, Indonesia
Researchers measured microplastic concentrations in surface waters of Banten Bay, Indonesia, across five sampling sites representing different human activities. They found concentrations ranging from 0.12 to 1.03 particles per liter, with fragments and fibers being the most common types, primarily made of polypropylene and polyethylene. The study links microplastic prevalence to domestic waste and human activities in the surrounding area.
Analysis of abundance of microplastic in fish caught in Percut Waters
Researchers analyzed the abundance of microplastics in fish caught in Percut Waters along the coast of North Sumatra, finding that microplastics have accumulated in fish tissues as a result of anthropogenic activities in the area. The study contributes to understanding the extent of microplastic contamination in coastal fisheries of Indonesia.
