Abstract

The degradation of coral reefs and threats to turtle populations due to anthropogenic activities in Pante Paku Village, Jangka Sub-District, Bireuen District, have prompted the implementation of a community-based marine ecosystem conservation program. This program aims to conserve coral reefs and protect turtles through a participatory approach. A qualitative descriptive method was adopted, involving initial surveys, program socialization, community training, and ecosystem monitoring. The implementation of these activities coincided with the Student Organization Capacity Building Program (PPK Ormawa). The establishment of a Tourism Awareness Group (POKDARWIS) was also carried out within this program, making it a key strategy in increasing community participation in the sustainable management of coastal resources. Training activities focused on coral reef conservation through transplantation methods using rafts or concrete substrates, and turtle habitat protection through beach cleaning and the construction of semi-natural hatcheries. Monitoring activities, conducted from August to October 2024, used the Line Intercept Transect (LIT) method to evaluate coral reef conditions and collect turtle population data. The results of the program implementation indicate that this approach is effective in increasing public literacy and awareness regarding the importance of maintaining the sustainability of marine ecosystems. In conclusion, this program not only contributes to the preservation of marine biodiversity but also strengthens the socio-economic aspects of coastal communities through the sustainable utilization of resources.

Abstract

Geomembranes are thin geosynthetic materials composed of polymeric layers that function as barriers in direct contact with soil. The properties of HDPE geomembranes suitable for application as vannamei shrimp (Litopenaeus vannamei) aquaculture. HDPE geomembranes applied in vannamei shrimp aquaculture are subjected to thermal loads (UV radiation), oxidative agents, and mechanical force such as interfacial friction and tensile loading in surface wear.  This study aims to improve the mechanical properties of the material by incorporating natural fibers as reinforcement into HDPE–ramie fiber biocomposite. The process of making HDPE–ramie fiber biocomposite uses an single screw extruder with a temperature of 170 oC, a rotation of 20 rpm with a ratio of HDPE waste and ramie fiber of 97.5:2.5, 95:5, and 92.5:7.5. The results of tensile and impact tests show the highest strength and toughness are shown in the HDPE sample and ramie fiber 92.5:7.5 with a value of 5.23 MPa and 96.17 kJ/m2. The highest material ductility was demonstrated in the HDPE and ramie fiber composite 97.5:2.5 with a value of 1.32%. In addition, the highest stiffness was demonstrated in the HDPE and ramie fiber composite 95:5 with a value of 845.40 MPa. The results of the morphological investigation showed that the bond between the matrix and filler was partially formed and the smallest fiber diameter was 4 µm.Keywords: HDPE, Ramie, Composite, Geomembrane, Vanamei
