Relationship Between Knowledge and Attitude of the Community with Blood Clam Processing Behavior in Rusun UPRS Blok G Muara Angke Jakarta in 2025
AI summary Read the abstract
A study of 117 coastal residents in Jakarta found that attitudes, not knowledge, significantly predict safe blood clam processing behavior, with only 64% showing good practices despite 76% having high awareness of microplastic risks. This gap between knowing and doing underscores the need for behavior-focused interventions in communities where microplastic-contaminated seafood is a daily dietary staple.
Blood clams are a seafood widely consumed by coastal communities, including in Muara Angke, Jakarta. However, blood clams are susceptible to microplastic contamination due to marine pollution. Consumption of seafood contaminated with microplastics can cause health impacts, such as organ and hormonal disorders. This study aims to determine the relationship between community knowledge and attitudes with blood clam processing behavior in Rusun UPRS Blok G Muara Angke. This study used a quantitative approach with a cross-sectional design. The sample consisted of 117 respondents from RT 10, RT 11, and RT 12, selected proportionally. The instrument was a questionnaire that had been tested for validity and reliability. The results showed that 76.1% of respondents had high knowledge, 56.4% had a positive attitude, and 64.1% showed good consumption behavior. The chi-square test showed no significant relationship between knowledge and consumption behavior (p = 0.074), but there was a significant relationship between attitude and consumption behavior (p = 0.014). These results indicate that attitude has a greater influence on safe processing behavior than knowledge. Further education is needed for the community regarding the dangers of microplastics and safe seafood processing methods.

Community knowledge, attitudes, and practices towards plastic pollution in Pujada Bay, Philippines: Relevance for UNESCO world heritage site nomination
AI summary Read the abstract
A survey of 366 residents near Pujada Bay in the Philippines found high awareness of plastic pollution's environmental and health impacts but moderate understanding of microplastic sources and a significant knowledge-behavior gap in waste management practices. Bridging this gap through targeted education is crucial for protecting this UNESCO World Heritage candidate site from ongoing plastic contamination threatening marine biodiversity.
Spatial Distribution of Microplastic Contamination in Blood Clams (anadara Granosa) on the Jeneponto Coast, South Sulawesi
AI summary Read the abstract
Researchers mapped the distribution of microplastic contamination inside blood clams (Anadara granosa) harvested along the Jeneponto coast of South Sulawesi, Indonesia. The highest microplastic levels were found in clams from mangrove ecosystems and residential waterways, while river areas showed the lowest contamination. Because blood clams are widely eaten as a daily food source, these findings raise direct concerns about microplastic ingestion by local populations.
Plastic waste characteristics and community responses in mangrove-influenced coastal villages of Kampung Laut, Cilacap, Indonesia
AI summary Read the abstract
This study characterized plastic waste composition and community responses in three mangrove-influenced Indonesian coastal villages using field surveys and a Knowledge-Attitude-Practice framework. Single-use polypropylene and polyethylene dominated the waste, and while knowledge influenced attitudes, sociodemographic constraints limited the translation of awareness into pro-environmental behavior.
Keberadaan mikroplastik pada kerang darah (Anadara granosa) dari TPI Tambak Lorok, Semarang
AI summary Read the abstract
Researchers in Semarang, Indonesia, found microplastics in blood cockles (Anadara granosa) sold at a local fish market, with fibers and fragments being the most common types identified under microscopy. The study also tested whether washing the shellfish before analysis affected results, finding contamination was present regardless. Because blood cockles are a widely consumed seafood in the region and are filter feeders that concentrate particles from the water column, this finding signals a direct route for microplastic ingestion by local populations.
