Diving ecotourism is a form of adventure tourism that has high economic value in marine ecosystems, especially coral reef ecosystems, contributing at least 4 billion USD annually in the Southeast Asian region. In particular, diving tourism worth more than 150 million USD has contributed significant income and employment to many islands and coastal communities in Southeast Asian countries. Another research have a plan that blue economy become base of scuba diving eco-tourism as economic concern and use community-based ecotourism (CBET) within the developing market dynamics of the blue economy. Many coastal communities around the world are strongly dependent on the need to find a balance between protecting marine biodiversity and maintaining a sustainable and direct access to ecosystem services. Healthy coastal ecosystems support livelihoods and provide protection from natural hazards, coastal erosion and rising sea levels, particularly in small island developing states. The blue economy discourse has made considerable inroads towards bridging the gap between livelihoods and ocean health. Although different actors involved in marine and ocean governance are using the blue economy term in competing and often conflicting ways, the wider consensus is that economies and human wellbeing rely on healthy eco-systems. Scuba diving tourists can help fund marine conservation initiatives and research. Some dive operators, for example, contribute a percentage of their income to marine conservation groups or engage in citizen science pro-grams that collect data on marine ecosystems. Scuba diving tourism can help safeguard marine habitats and encourage sustainable practices by funding research and conservation activities. Overall, scuba diving tourism provides a one-of-a-kind opportunity to enjoy the beauty and diversity of marine ecosystems while also offering considerable economic benefits and aiding marine conservation.

Octopus is a valuable seafood product consumed in many countries worldwide, with a billion-dollar industry and different species and markets in various regions. However, the octopus industry faces challenges related to sustainability, quality control, and food safety. This paper aims to provide an overview of the current state of the octopus industry, highlighting key issues and potential solutions. The sustainability of octopus fisheries is a major concern due to their vulnerability to overfishing and the lack of effective management strategies. Octopus fisheries are often unregulated, and there is a need for effective management strategies that balance conservation and economic interests. This can include implementing measures such as closed seasons, gear restrictions, and size limits to protect the species and ensure the long-term sustainability of octopus fisheries. Overall, the octopus industry has a promising future, but it will require continued innovation and collaboration to overcome the challenges facing the industry and ensure the sustainability and safety of octopus products. Effective management strategies, quality control measures, and food safety protocols must be implemented to maintain the long-term viability of the industry and ensure the health and safety of consumers.

Seaweed has emerged as a promising bioremediation agent for addressing heavy metal contamination in aquatic environments. This study presents a comprehensive review of ten selected references to explore the potential of seaweed-based bioremediation and its implications for environmental sustainability. The findings highlight the significant capacity of seaweed species to accumulate heavy metals, emphasizing the importance of species selection based on their metal uptake capabilities. Seaweed biomass and biochar demonstrate remarkable adsorption properties, providing efficient means of removing heavy metals from contaminated water through physical adsorption and ion exchange processes. Seaweed-based bioremediation techniques offer several advantages over traditional methods. The studies underscore the importance of considering environmental conditions and the presence of coexisting pollutants in designing seaweed-based bioremediation strategies. Optimal light availability, temperature, nutrient levels, and water quality parameters are critical for maximizing seaweed's metal removal efficiency. Overall, seaweed-based bioremediation offers a promising and sustainable approach for addressing heavy metal pollution in aquatic environments. Future research should focus on overcoming challenges related to biomass management, ecological impacts, and scaling up cultivation and processing methods to ensure the widespread implementation of this eco-friendly solution.

The dugong (Dugong dugon) is a large marine mammal belonging to the order Sirenia and is one of four living species of sea cows, along with the manatees. Dugongs are found throughout the Indo-Pacific region, inhabiting shallow coastal waters, estuaries, lagoons, and seagrass beds, making them highly dependent on seagrass ecosystems for their survival. The dugong is classified as vulnerable to extinction by the International Union for Conservation of Nature (IUCN), with population declines attributed to habitat loss, hunting, accidental capture, and climate change. Therefore, conservation efforts are essential to ensure the survival of the dugong and the maintenance of the ecological services provided by seagrass ecosystems. The current state of knowledge on dugongs and their conservation can be synthesized based on the findings of the ten selected references. Overall, these references provide evidence for the importance of seagrass meadows as habitat and food source for dugongs, as well as for the numerous threats facing this species. Overall, the reviewed literature underscores the importance of engaging local com-munities in dugong conservation efforts. Community-based conservation interventions have the potential to reduce hunting pressure on dugongs and promote positive attitudes towards conservation. Furthermore, the recognition of the cultural significance of dugongs can foster greater community involvement and support for conservation initiatives.

Photosynthesis is the process of synthesizing inorganic materials (CO2 and H2O) in pigmented plants with the help of solar energy. CO2 and H2O are substrates in photosynthesis reactions and with the help of sunlight and photosynthetic pigments consisting of chlorophyll and other pigments will produce iron and release oxygen. Basically, sequential reactions can be divided into two main parts, namely the light reaction (receives light) and the dark reaction (does not require light but requires carbon dioxide). Photosynthesis is influenced by many factors, both internal and external factors. Internal factors include the age of the leaves, the state of the stomata, and the type of plant. External factors include CO2 and O2, water availability, humidity and air temperature, light conditions. In the light reaction stage that occurs in the grana, light energy is shown to be energy consisting of NADPH2 and ATP. Then in the dark reaction stage, which is carried out in the stroma, NADPH2 and ATP are used as biochemical reducing agents to convert carbon dioxide into transport. Growing water releases oxygen into the air. The released oxygen will dissolve in the air and form dissolved oxygen. The photosynthesis practicum was carried out at the Microbiology and Molecular Biotechnology Laboratory, FPIK, Padjadjaran University. Performed on hydrilla plants.
