Abstract

Cultivating fattening mud crabs (Scylla serrata) usually requires a large area of land, innovation is carried out by making crab apartments. The research was conducted in September – November 2023, crab fattening locations in Pagarawan Village and Takari Beach, Bangka Regency. Location of mud crab morphometric measurements at the Aquatic Resources Management Laboratory, Bangka Belitung University. Test protein content at the DKI Jakarta Regional Health Laboratory. This research aims to examine the morphometrics, protein content and survival of mud crabs in crab apartments in Pagarawan Village and Takari Beach. Experimental research methods and community involvement to measure morphometrics, protein content and crab survival. The results of the research show that the ratio between weight, width and length of mangrove crabs in Pagarawan is 1.6:1.4:1. This shows that mud crabs are fatter. When the crab weighs around 160 grams, it is likely that the carapace width is ±14 cm and the carapace length is ±10 cm, while the crabs in Takari are smaller and thinner. The protein content of mangrove crabs in Pagarawan has an average value of 17.5 gr/100gr and in Takari 15.1 gr/100gr. The survival rate (SR) of mangrove crabs in Pagarawan is 87%. This condition means that crabs are suitable for cultivation in crab apartment boxes with a water source from a recirculation system pond. It is assumed that water pollution due to ammonia will not have much of an impact. The survival rate for mud crabs in Takari shows a zero percentage. The narrow space, food waste, and circulating water with an ammonia content of up to 0.05 mg/l are thought to have contributed to the crab's death. Water quality in both crab rearing areas shows that temperature, pH, salinity, DO, ammonia, nitrate and phosphate are still within the normal range for rearing mud crabs.

Abstract

Batu Belubang Beach has abundant biological resources of Darah Mussels (Anadara granosa) and Kepah Mussels (Meretrix meretrix) in season. On the other hand, Batu Belubang waters are a post-tin mining area, therefore it is a concern for people to consume shellfish from the area. This concern is caused by the results of previous studies that said that post-tin mining areas left heavy metals, one of which was non-essential heavy metals such as Pb and Cu.  Therefore, this study aims to examine the heavy metal content of Cd and Pb in shellfish meat, and determine the condition of gill tissue and meat of Darah Mussels (Anadara granosa) and Kepah Mussels (Meretrix meretrix) from Batu Belubang. This research method is purposive sampling, and several analyses consisting of: analysis of heavy metals in sediment and meat, tissue observation from muscle/meat and gill histology. The results showed that the concentration of heavy metals Cd, Pb in sediment is still below the quality standard, this is due to the sediment texture at Batu Belubang Beach dominant with sand, so it has a low binding power to heavy metals. The concentration of heavy metals in meat is also still below quality standards, so it is still safe for consumption. This condition is also strengthened by the results of tissue observations that show the condition of the flesh and gill tissues has not been damaged. This condition shows that both shells have not experienced tissue disruption because the accumulation of heavy metals is still very low.

Abstract

Developing tourist attractions can encourage increased community participation in managing tourist destinations, especially those based on water resource potential. Local or domestic tourists are the backbone of most tourism destinations. Therefore, challenges, opportunities, and innovation in optimizing the potential of aquatic resources require sharing information based on experience in several regions. The research aims to assess the potential for sustainable water resource-based tourist attractions. This research was conducted from March 2022 to August 2023 in 9 districts/cities with tourist destinations. The method uses qualitative methods through field observations and literature studies. The results show that coastal tourism management must consider tourist attractions, carrying capacity, infrastructure, facilities, and services. Tourist attractions can motivate tourists to visit. Tourists find out about tourist destinations usually based on information from the internet, from friends/relatives, and social media. Clean water facilities at tourist locations are essential, especially during peak season. The sources of income for tourism managers comes from entrance tickets to tourist locations, sponsorships, and rides. The mode of transportation for domestic tourists is dominated by cars and motorbikes. Some examples of tourist attractions visited include tourism educational activities such as salt making, mangrove crab rearing of apartment system, fishing, culinary, sponsorship, lodging, swimming pools, fish therapy, photo boats, viewing panoramic views of beaches, mangroves, swimming, snorkeling and diving on coral reefs. Tourist destinations provide economic benefits and sources of income. Sustainable tourism promotes economic growth, social inclusion, environmental protection, and tourism governance.
