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.

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}

A study regarding the different culture methods on the growth performance of K. striatum in Pelakak Village waters, Lingga District, Riau Islands has never been reported. This study aimed to determine the effect of different culture methods on the growth performance of Kappaphycus striatum seaweed. This study used a completely randomized block design with three treatments and three replications, namely bottom method (P1), off-bottom (P2), and longline method (P3). There were 351 seaweed seeds with 100 g weight per each seed, that are placed in nine culture plots. The culture plot was constructed as a 4 m × 1.5 m square with wooden stakes at both ends and polyethylene ropes installed at a distance of 0.5 m. Each rope stretch was tied at 0.3 m distance for seed planting. Parameters observed in this study were absolute growth rate, specific growth rate, and production rate of the seaweed. The results showed that the absolute growth rate, specific growth rate, and production rate were affected by the culture method (p<0.05). The seaweed group reared in a longline method (P3) obtained the best results, compared to other methods, at 2.34% per day for specific growth rate and 245.7 g/m 2 for production rate.

From this problem, the condition of the border area can harm the site, one of which is people smuggling. So, from this, the researcher aims to examine the problem of handling people smuggling crimes in the border area of the Batam City case study. The research method carried out is descriptive qualitative. Researchers also obtained primary data from various interviews with related agencies and different secondary data in addition to completing this study. The interim result of this study is the problem of transnational crime. This study’s provisional result is that international crime is crossing the boundaries of a country whose actions have detrimental and dangerous effects. One of the ways to overcome this problem is the United Nations Convention Against Transnational Organized Crime (UNTOC), which aims to eradicate transnational organized crime, one of which is related to people smuggling. In Indonesia, there is Law No. 6 of 2011 concerning Immigration, which also regulates people smuggling crimes in Indonesian territory, including Batam City. This law is one of the efforts to prevent people smuggling crimes. The border area as the front guard in maintaining the stability of the Republic of Indonesia must be maintained and supported.

With the classic processing of deep-fried nuggets, there is a rather large loss of product mass, and when using bad oil, the taste of the product is lost. Therefore, it is necessary to consider other types of heat treatment of this product to reduce production costs. The authors of the article conducted an experiment on alternative processing of nuggets in such equipment as a combi steamer and oven. The purpose of the experiment is to establish the weight loss of the product when using these types of heat treatment and to conduct an organoleptic evaluation of the resulting product. Raw materials were used from the manufacturer Meat Master LLC. The study was carried out according to 2 approved technologies on different equipment. The total weight loss of nuggets during processing in a combi steamer averaged 18%, and in an oven 13%. At the same time, processing in a combi steamer, in comparison with an oven, made it possible to better preserve the organoleptic properties of the nuggets. Also, thanks to the experiment, it was revealed that it takes time to bring the nuggets to culinary readiness, since during the experiment, the internal temperature of the product was recorded at intervals of 30 seconds. The product was prepared not by time, but by reaching a temperature in the depth of the product up to 800C. It was found that the average cooking time for nuggets in a combi oven is 6 minutes, and in an oven about 10 minutes. The results were the achievement of the goal of the experiment and the solution of related problems. The simulated cooking model made it possible to identify the time to bring to culinary readiness, the mass of losses and the organoleptic properties of nuggets cooked in a combi steamer and oven.","PeriodicalId":8805,"journal":{"name":"BIO Web of Conferences","volume":"22 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":"135549677","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}
