Abstract

Microplastic pollution in coastal areas has become a serious concern due to its impact on marine environments and human health. This study examined the presence of microplastics in the digestive tracts of the tongkol fish (Euthynnus affinis) collected from two locations in Kupang Bay, namely PPI Oeba and Pasar Oesapa. A total of 16 fish samples were analyzed visually using a microscope, followed by polymer identification using Fourier Transform Infrared Spectroscopy (FTIR). Results showed that fish from PPI Oeba contained 25 microplastic particles, while those from Pasar Oesapa had 20 particles. Film-type microplastics dominated, accounting for 68% in PPI Oeba and 75% in Pasar Oesapa, followed by fibers (20% and 25%, respectively), and fragments were only found in PPI Oeba (12%). Detected polymers included polyethylene (PE), polypropylene (PP), and polyvinyl chloride (PVC). This study confirms that tongkol fish can serve as effective bioindicators for monitoring microplastic pollution in the coastal waters of Kupang City.

Abstract

This community service activity aims to enhance students' and community members' knowledge, awareness, and participation in climate change mitigation efforts through socialization and mangrove seedling planting. The selection of mangrove seedling planting locations is based on observations of degrading mangrove forests that still have the potential for natural regeneration. In addition, the location is prioritized in areas experiencing anthropogenic pressure, coastal erosion, and excessive sedimentation. Socio-economic considerations are also a key factor. The planting location is close to residential areas to encourage public participation and environmental awareness. This activity is carried out in the mangrove forest tourism area, Oesapa village, Kelapa Lima sub-district, Kupang City, over a period of 2 months, namely November – December. The method for implementing the activity consists of three stages: socializing students about the role of mangrove forests; cleaning the area with the surrounding community; planting mangrove seedlings; and initial maintenance and monitoring. In addition to increasing knowledge and awareness of mangrove forests' functions, this activity also contributes to the rehabilitation of mangrove areas. It strengthens collaboration among students, the community, the government, and academics in the effort to preserve mangrove forests.
