This study aims to evaluate public policy in the implementation of the Blue Economy concept in Indonesia to anticipate disasters. The research method used is qualitative with literature study as the main approach. The research findings show that existing policies related to the Blue Economy concept and disaster anticipation in Indonesia still need to be improved and strengthened in terms of application and coordination between sectors. The policy cycle in the Blue Economy concept is needed to formulate agendas, policy formulation, policy adoption and legitimacy, and policy assessment and evaluation. Challenges faced in the Blue Economy concept include the application of ecosystem principles, the development of environmentally friendly technology, increasing community involvement, and aligning government policies. In planning and implementing public policies in the Blue Economy concept, collaboration is needed between government, community, private sector, and academic institutions. Thus, synergy is created in building environmentally friendly economic sustainability and reducing disaster risks that impact human life and the surrounding environment.","PeriodicalId":8805,"journal":{"name":"BIO Web of Conferences","volume":"143 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135447634","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The magnetite (Fe 3 O 4 ) was synthesized using iron precursor from the zircon mining magnetic waste. The MIL-100(Fe) was composited with magnetite using a room-temperature in situ synthesis method. The MIL-100(Fe)@Fe 3 O 4 composite obtained was then characterized using the Fourier transform infrared spectroscopy and X-ray diffraction. The synthesized MIL-100(Fe) and MIL-100(Fe)@Fe 3 O 4 were then used to adsorb methylene blue dye from aqueous phase. The maximum methylene blue removal from both adsorbents was obtained at pH of 9. The adsorption kinetics showed that the adsorption followed a pseudo second-order kinetics model with the rate constant values for MIL-100(Fe) and MIL-100(Fe)@Fe 3 O 4 were 1.012 x 10-2 and 3.963 x 10-2 g/mg.menit, respectively. The results also showed that the adsorption isotherm of MIL-100(Fe) and MIL-100(Fe)@Fe 3 O 4 follows the Langmuir isotherm for adsorption capacities were 137.70 and 151.47 mg/g, respectively. The results indicate that the iron content in the zircon mining magnetic waste as precursor for synthesis MIL-100(Fe)@Fe3O4 composite can be employed as an excellent adsorbent for removal of methylene blue dye from aqueous phase.","PeriodicalId":8805,"journal":{"name":"BIO Web of Conferences","volume":"257 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135447942","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To control parasite attacks, safe and easy control measures need to be taken, one of which is the application of turmeric juice to soak fish infected with leeches. Therefore, research must be conducted to test the most effective concentration and soaking time of turmeric ( Curcuma domestica ) juice to reduce the intensity of sea leech attacks on hybrid grouper fish. This study was to test differences in turmeric juice concentration using a completely randomized factorial design consisting of 2 factors, namely the turmeric juice concentration factor (0 mL/L, 0.6 mL/L, 0.9 mL/L and 1.2 mL/L seawater) and immersion time factor (30 and 60 minutes) with eight treatments and three replications. The research results showed that the most effective reduction in intensity after soaking with turmeric juice was at a concentration of 1.2 mL/L of seawater for 60 minutes at 24.00%. The interaction between the concentration and soaking time of turmeric juice reduced the intensity of parasites but did not affect the behaviour and survival of the fish. Turmeric juice has the potential as an anti-leech and can be applied in grouper cultivation to reduce the intensity of leech infections.","PeriodicalId":8805,"journal":{"name":"BIO Web of Conferences","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135448486","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, it is imperative to seek out natural products that are safe for combating fish diseases. This research aims to assess the antibacterial properties of an extract derived from Muntingia calabura against various bacteria, including A. hydrophila, A. salmonicida, E. ictaluri, P. aeruginosa, E. tarda, and V. alginolyticus. M. calabura extract was obtained by soaking with ethanol solvent. This extract has been tested for phytochemical content and characterized by FT-IR. The antibacterial activity of the M. calabura extract was evaluated using the agar diffusion method, employing concentrations of 100, 200, 300, 400, and 500 mg mL-1. The phytochemical analysis of the M. calabura extract revealed the presence of flavonoids, phenolic compounds, saponins, and terpenoids. The results of the FT-IR characterization of M. calabura extract contained O-H, C=O, C=C aliphatic, C=C aromatic and C-O groups. The inhibition tests demonstrated that the M. calabura extract effectively hindered the growth of A. hydrophila bacteria by a range of 8.1 mm to 14.2 mm, A. salmonicida by 9.2 mm to 10.9 mm, E. ictaluri by 8.8 mm to 11.5 mm, P. aeruginosa by 8.1 mm to 12.1 mm, E. tarda by 9.6 mm to 11.4 mm, and V. alginolyticus by 8.2 mm to 12.2 mm. In summary, the extract from M. calabura has the potential to effectively on paper plates and incubated at 30°C for 24 hours.","PeriodicalId":8805,"journal":{"name":"BIO Web of Conferences","volume":"297 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135448729","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional fishing communities on Riau Island have thrived for generations, drawing on ancestral wisdom and local expertise. However, the swift rise of digitalization and modernization has triggered a transformative shift in their learning methods and adaptation strategies. This study focuses on: identifying methods of knowledge acquisition, investigating adaptive strategies, unveiling challenges, and exploring knowledge preservation techniques. Through in-depth interviews with more than two decades of experienced fishermen, qualitative data was gathered and meticulously analyzed using NVivo 12 software. The result found that traditional fishermen employ diverse strategies, integrating technology, continuous learning, and data-driven decision-making. They face challenges like limited internet access, cultural traditions, and safety concerns. Yet they preserve wisdom through oral traditions, apprenticeships, and modern tools, ensuring a vibrant fishing legacy. Their resilience highlights the urgent need for digital adaptation and intergenerational dialogue to shape sustainable and innovative fishing communities. Hence, this study recommend to develop sustainable training initiatives, establish community platforms, formulate policies to enhance digital accessibility, and encourage meaningful conversations across generations within traditional fishing communities.","PeriodicalId":8805,"journal":{"name":"BIO Web of Conferences","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135448861","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The mangrove sylvo-ecotourism area in Tanjungpiayu Village, Batam City, is part of the forest and land rehabilitation program carried out by BPDAS Sei Jang Duriangkang in the Riau Islands region. In an effort to provide data and information regarding the potential for carbon absorption in mangrove forest ecosystems resulting from the rehabilitation program, it is necessary to calculate the stored carbon stock as a reference for monitoring in subsequent years. The research was carried out from August to September 2023. The method used was the roaming method without harvesting using an allometric model. Data analysis was carried out by calculating the value of biomass, carbon stock and CO2 absorption. The analysis results show that the average total mangrove biomass at the top surface (ABG) and below the surface (BGB) is 420.50 tons/Ha with a biomass composition of AGB of 265.23 tons/Ha, and BGB of 155.27 tons/Ha.
