Specifically, Kappaphycus striatum has recently been cultured for the last three culture periods. This condition causes the seaweed culturists have no appropriate data associated with a proper culture method, following the water characteristics around the culture area. 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. Therefore, the longline method can be applied in the Pelakak Village waters, Lingga District.","PeriodicalId":8805,"journal":{"name":"BIO Web of Conferences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135448934","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}

Batam is one of the areas included in the Riau Islands and is directly adjacent to neighboring Malaysia and Singapore. The border area owned by Batam has strategic problems to be studied. 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. Because people smuggling has very potential as a gateway in and out of international criminal acts such as narcotics, human trafficking.","PeriodicalId":8805,"journal":{"name":"BIO Web of Conferences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135449567","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}

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":null,"pages":null},"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}

It has been established that the group hydrocarbon composition of the liquid oxycracking catalyzate is significantly affected by the process parameters. When considering the influence of the process temperature, it was found that the concentration of C 5 -C 9 and C 10+ alkanes has an opposite temperature dependence: the C 5 -C 9 yield passes through a maximum at a temperature of 500°C, while for C 10+ it is a minimum temperature; there is a linear relationship between the temperature and the yield of unsaturated; the yield of naphthenes gradually decreases with increasing temperature; elevated temperatures contribute to an increase in the total yield of aromatic hydrocarbons. When varying the duration of the process, it was revealed: within 900 seconds from the beginning of the process, the most significant decrease in concentration was noted for aromatic hydrocarbons. The low oxidation state of 0.5% contributes to the intensive conversion of high molecular weight alkanes and aromatic hydrocarbons with long side chains; the concentration of oxygen-containing compounds raises with an increase in the degree of oxidation to 1%, passing through a maximum. The contact time with the catalyst had a complex effect on the hydrocarbon composition of the liquid products of vacuum gas oil oxycracking: a short contact time contributes to a decrease in the concentration of high molecular weight paraffinic and naphthenic hydrocarbons and an increase in aromatic hydrocarbons; with a subsequent increase to 2 s, it drops sharply. The obtained data made it possible to establish the fundamental distinguishing features of the catalytic oxycracking of vacuum gas oil from the traditional catalytic and noncatalytic oxidative ones, and also to propose a list of reactions occurring during the catalytic oxycracking of vacuum gas oil.","PeriodicalId":8805,"journal":{"name":"BIO Web of Conferences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135550006","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 main physiological and biochemical characteristics associated not only with the functionality of plants, but also involved in the formation of the plant's response to stress are involved for evaluation. It is shown that species differ in their physiological and biochemical characteristics and different reactions are observed in species to anthropogenic stressors. A significantly lower number of all groups of photosynthetic pigments was observed in species A. negundo and A. saccharinum, A. negundo it also differs in low indicators of the specific surface area of the sheet. In all five maple species in the urban environment, there was a significant increase in the total fund of green and yellow pigments compared to the background; there is an increase in the ratio Σchl / Σcar by 1.1-1.7 times, mainly due to a decrease in the level of chlorophylls and an increase in the proportion of carotenoids. A. negundo has significantly lower water deficiency and water loss by leaf tissues. The highest values of ascorbic acid were noted in the species A. saccharinum . To interpret the responses of species to the stressors of an urbanized area, cluster analysis was used, which divided the species into two clusters; at the same time, common mechanisms of responses were identified in maples that are introduced from different habitats.","PeriodicalId":8805,"journal":{"name":"BIO Web of Conferences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135550036","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}

In this study, oil-containing wastes were considered as substrates - waste frying sunflower oil and petroleum-contaminated soil. At the first stage of research, we screened native waste microorganisms capable of synthesizing biosurfactants. As a result of the study, strains with the ability to form biosurfactants were isolated. Six strains (A, B, C, D, E, F) were isolated from waste frying sunflower oil, two strains (A1, B1) were isolated from petroleum-contaminated soil. The highest yield of biosurfactants is typical for strains A and A1 - 0.429 and 0.502 mg ml -1 , while the best ratio of biosurfactant mass to cell biomass is typical for strains A1 and E - 0.9 and 0.6.

The bird taken for the experiment was bred in “itself” for a long time and did not give splitting in plumage color. The aim of the work was to find methods for separating guinea fowls by sex at an early age, based on the use of marker genes and their modifiers. It has been established that gray-speckled, blue and Zagorsk white-breasted guinea fowls belong to the eumelanin phenotype in terms of plumage color. The deposition of eumelanin pigment in down and feathers of guinea fowls is controlled by the gene alleles of the E/e locus. Limitation of pigment deposition in feathers, certain parts of the body, Zagorsk white-breasted guinea fowls is determined by the action of the Zn/zn (Zonal) gene, the manifestation of pearl spots is determined by the action of the Sp/sp gene, the autosomal gene Bl (Blokator) determines the saturation of eumelanin colors, and Ig (Inhibitor) blocks the deposition of the pheomelanin pigment. According to the color of the plumage, cream guinea fowls belong to the pheomelanin phenotype and are distinguished by the white-cream color of the plumage. The presence in the plumage of pheomelanin controlled by the genes for silverness “S” and goldenness “s” and the presence of the Ig (Inhibitor) gene blocking the deposition of the pigment pheomelanin in the down and re-determines the autosex color of the plumage. Based on this, the work concluded that cream guinea fowls are promising in creating an autosex cross on their basis.","PeriodicalId":8805,"journal":{"name":"BIO Web of Conferences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135504657","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}
