This research was conducted from December 2021 to February 2022 in Balunijuk Village, Merawang District, Bangka Regency, Bangka Belitung Islands Province. The method used primary and secondary data which was analyzed with a qualitative descriptive approach to policy and vaname shrimp culture. The results showed that designing sustainable development must follow the vision, mission, goals, policies, strategies, programs, to the implementation of activities. One of the priority policies related to food and nutrition action plans or food security was by utilizing marine resources. Food security by utilizing resources from the sea was known as the blue economy concept. Sustainable marine development policies required political effectiveness for the benefit of communities and ecosystems. The application of the blue economy concept with vaname shrimp cultivation in biofloc tarpaulin ponds technically required the measurement of standard parameters such as dissolved oxygen (DO), ammonia (NH3), nitrite (NO2), nitrate (NO3), phosphate (PO4), TDS, brightness, depth, water temperature, salinity, and water pH. Water quality data showed that it could still be tolerated, did not exceed its carrying capacity, and was still in standard water conditions for aquaculture. The implementation of vaname shrimp cultivation in biofloc tarpaulin ponds could increase economic benefits in a sustainable manner, increase healthy products with environmentally friendly technological innovations using Probio_FmUBB probiotics, provide access to small-scale artisanal fisheries, and open market access.

This study aimed to synthesize calcium phosphate loaded with silver nanoparticles and evaluate its antibacterial activity. We used cockle shells waste as raw material to prepare calcium phosphate. X-ray diffraction analysis showed that the constituent phases of calcium phosphate consist of hydroxyapatite (HA) and β-tricalcium phosphate (β-TCP). The incorporation process of silver nanoparticles on calcium phosphate was carried out in colloidal silver nanoparticles via the green-synthesis method using Citrus x microcarpa Bunge peel extract. The presence of colloidal silver nanoparticles through the green synthesis method was identified using UV-Vis spectrophotometer by the peak of the absorption band that occurred at 468 nm. The incorporation of silver nanoparticles into calcium phosphate did not significantly change the crystalline properties of HA and β-TCP. Evaluation of the antibacterial activity showed the silver nanoparticles had a strong antibacterial effect against Staphylococcus aureus, which also occurs in calcium phosphate loaded by silver nanoparticles. After being incorporated with silver nanoparticles, Calcium phosphate generally has no antibacterial effect. After being incorporated with silver nanoparticles, an inhibition zone with a diameter of about 9.8 mm can form. These results indicated that the method proposed in this study could be an alternative for developing calcium phosphate, which requires self-sterilization properties.

The ecological impacts of tin mining activities in the Bangka island is the presence of heavy metal contamination that accumulated in the environment. One of the heavy metals that was often found in post-tin mining areas is lead (Pb). Mycoremediation is a method that can be used to reduce lead pollution in post-tin mining areas. This study aimedto isolate, resistance test and identify to Pb-resistant soil fungi (rhizosphere) in the post-tin area of Bangka. The research methods included isolation, test of fungal resistance to Pb metal (Control, 150ppm, 250ppm, 350ppm, 500ppm, 1,000ppm, 5,000ppm and 10,000ppm), macroscopic and microscopic identification. The results showed that 9 isolates tested, there were 6 isolates that were resistant to Pb up to the concentration of 5,000 ppm, namely isolates I1(Rhizoctonia), I2(Penicilllium sp1), I5(Papulaspora), I6(Penicillium sp2), I7(Penicillium sp3) and I9 (Sclerotium). Three isolates of soil fungus were not resistant to Pb up to a concentration of 5,000 ppm, namely isolates I4 (Sclerotium), I8(Microsporum), and I10(Cladosporium). All isolates did not grow anymore at a concentration of 10,000 ppm of Pb.
