Authors: Ruy Dambroz Felipe , Teoldo Israel , Prímola-Gomes Thales Nicolau
Published: February 2021

Soccer is a sport practiced in an open environment and is under the interference of the local environmental conditions of the game. Different environmental conditions, such as heat, relative humidity, cold and altitude can cause changes in the players’ body homeostasis. Thus, this study aimed to verify the effect of different ambient temperature on the tactical, technical and physical performances of national teams in World Cup. The sample was composed by FIFA World Cup games played in Brazil/2014 (n=64; 24.98±4.51°C), and South Africa/2010 (n=61; 14.69±4.70°C). The data were obtained from FIFA website. Temperature was categorized in four ranges: ≤10°C; 11–20°C; 21–30°C; ≥31°C. The tactical (% ball possession time in each sector of the field), technical (% successful conclusions, % successful short, medium, long and total passes) and physical (distance covered) performances of the teams were compared based on temperature ranges. Kolmogorov-Smirnov test, ANOVA One-Way and Kruskal-Wallis (p<0,05) were used to compare the averages by temperature range, in addition to the Tukey and Mann-Whitney tests (post-hoc). The results showed that the ambient temperature had an influence on the time of possession of the ball in the defensive (p<0.001), midfield (p<0.004) and offensive (p <0.001). In addition, in relation to technical performance, warmer temperatures positively influenced the percentage of correct passes for short (p<0.028), medium (p <0.014), long (p<0.001) and total (p<0.001), in addition to the percentage of correct shots on goal (p<0.001). On the other hand, with regard to physical performance, warmer temperatures negatively influenced the total distance covered (p<0.001). The ambient temperature influenced the tactical, technical and physical performance of the national teams. In the World Cup, in matches played in warmer temperature ranges, the teams suffered a change in tactical performance, showed improvement in technical performance, and losses in relation to physical performance.

Published: February 2021

This paper considers comparative evaluation of recent methods for grip point determination for manipulations with objects in the scene. This research is aimed to compare and evaluate the modern approaches of grip point determination, when this process is aided by computer vision. The methods of object gripping, considered in this paper, are employed in connection with depth map composition, backed by neural network model ResNet-50, which allowed to omit application of specific depth sensors in the course of experiments. This research shows dependencies of successful grip probability from the things being manipulated. Probability scores, averaged over different types of objects for the methods GPD, 6-DOF GraspNet, VPG, were, accordingly, 0.690, 0.741, 0.613. The paper also considers dependencies of successful grip probability from object sizes, distances from the capturing camera and target objects in the scene, luminosity levels, as well from the angles of scene inspection along the vertical axis. In terms of the considered methods GPD, 6-DOF GraspNet, VPG, non-linear increasing dependencies are revealed for object type-averaged probabilities of successful grip from luminosity level of the scene. It was also discovered, that the dependencies of successful grip for all the other parameters are non-linear and non-monotonic. The ranges of the values for scene parameters under consideration are defined in this paper, which ensure the highest probability values for object grip in these approaches. Upon the results of the performed experimental evaluation, the 6-DOF GraspNet solution showed the best performance for the vast majority of the considered parameters of the scene. The approach, presented in this paper, is the preferable way for solution of grip point problem, in context of methods, which assume depth map reconstruction without specific equipment.
Roots of Incivility: How Personality, Media Use, and Online Experiences Shape Uncivil Participation
Authors: Frischlich Lena , Schatto-Eckrodt Tim , Boberg Svenja , Wintterlin Florian
Published: February 2021

Online media offer unprecedented access to digital public spheres, largely enhancing users’ opportunities for participation and providing new means for strengthening democratic discourse. At the same time, the last decades have demonstrated that online discourses are often characterised by so-called ‘dark participation’ the spreading of lies and incivility. Using ‘problematic behaviour theory’ as framework and focusing on incivility as a specific form of dark participation, this article investigates the role of users’ personal characteristics, media use, and online experiences in relation to offensive and hateful online behaviour. Using a random-quota survey of the German population, we explored how dark personality traits, political attitudes and emotions, the frequency and spaces of online-media use, and users’ experiences with both civil and uncivil online discourses predicted participants own uncivil behaviour, such as posting, sharing, or liking uncivil content. We found that 46% of the participants who had witnessed incivility in the last three months also engaged in uncivil participation. A hierarchical logistic regression analysis showed that incivility was associated with manipulative personality traits as measured by the dark triad, right-wing populist voting intentions, and frequent social-media use. Experiences with both civil comments and hate speech predicted higher levels of uncivil participation. The strongest predictor was participants’ personal experiences with online victimisation. Overall, the results confirmed that dark participation in the sense of uncivil engagement results from the interplay of personality traits, an online environment that allows for deviant engagement, and, most importantly, participants’ experiences in said environment.
From Insult to Hate Speech: Mapping Offensive Language in German User Comments on Immigration
Authors: Paasch-Colberg Sünje , Strippel Christian , Trebbe Joachim , Emmer Martin
Published: February 2021

In recent debates on offensive language in participatory online spaces, the term ‘hate speech’ has become especially prominent. Originating from a legal context, the term usually refers to violent threats or expressions of prejudice against particular groups on the basis of race, religion, or sexual orientation. However, due to its explicit reference to the emotion of hate, it is also used more colloquially as a general label for any kind of negative expression. This ambiguity leads to misunderstandings in discussions about hate speech and challenges its identification. To meet this challenge, this article provides a modularized framework to differentiate various forms of hate speech and offensive language. On the basis of this framework, we present a text annotation study of 5,031 user comments on the topic of immigration and refuge posted in March 2019 on three German news sites, four Facebook pages, 13 YouTube channels, and one right-wing blog. An in-depth analysis of these comments identifies various types of hate speech and offensive language targeting immigrants and refugees. By exploring typical combinations of labeled attributes, we empirically map the variety of offensive language in the subject area ranging from insults to calls for hate crimes, going beyond the common ‘hate/no-hate’ dichotomy found in similar studies. The results are discussed with a focus on the grey area between hate speech and offensive language.
Digital Civic Participation and Misinformation during the 2020 Taiwanese Presidential Election
Authors: Chang Ho-Chun Herbert , Haider Samar , Ferrara Emilio
Published: February 2021

From fact-checking chatbots to community-maintained misinformation databases, Taiwan has emerged as a critical case-study for citizen participation in politics online. Due to Taiwan’s geopolitical history with China, the recent 2020 Taiwanese Presidential Election brought fierce levels of online engagement led by citizens from both sides of the strait. In this article, we study misinformation and digital participation on three platforms, namely Line, Twitter, and Taiwan’s Professional Technology Temple (PTT, Taiwan’s equivalent of Reddit). Each of these platforms presents a different facet of the elections. Results reveal that the greatest level of disagreement occurs in discussion about incumbent president Tsai. Chinese users demonstrate emergent coordination and selective discussion around topics like China, Hong Kong, and President Tsai, whereas topics like Covid-19 are avoided. We discover an imbalance of the political presence of Tsai on Twitter, which suggests partisan practices in disinformation regulation. The cases of Taiwan and China point toward a growing trend where regular citizens, enabled by new media, can both exacerbate and hinder the flow of misinformation. The study highlights an overlooked aspect of misinformation studies, beyond the veracity of information itself, that is the clash of ideologies, practices, and cultural history that matter to democratic ideals.

Published: February 2021

The aim of this paper is to present the estimation procedure for the step-stress partially accelerated life test model under the generalized progressive hybrid censoring scheme. The uncertainties are assumed to be governed by Lindley distribution. The problem with point and interval estimation of the parameters as well as the acceleration factor using maximum likelihood approach for the step-stress partially accelerated life test model has been considered. A simulation study is conducted to monitor the performance of the estimators on the basis of the mean squared error under the considered censoring scheme. The expected total time of the test under an accelerated condition is computed to examine the effects of the parameters on the duration of the test. In addition, a graph of the expected total time of the test under accelerated and un-accelerated conditions is provided to highlight the effect due to acceleration. One real data set has been analyzed for illustrative purposes.
Robust Estimation for a Generalised Ratio Model
Authors: Wada Kazumi , Sakashita Keiichiro , Tsubaki Hiroe
Published: February 2021

It is known that data such as business sales and household income need data transformation prior to regression estimate as the data has a homoscedastic error. However, data transformations make the estimation of mean and total unstable. Therefore, the ratio model is often used for imputation in the field of official statistics to avoid the problem.
Our study aims to robustify the estimator following the ratio model by means of M-estimation. Reformulation of the conventional ratio model with homoscedastic quasi-error term provides quasi-residuals which can be used as a measure of outlyingness as same as a linear regression model. A generalisation of the model, which accommodates varied error terms with different heteroscedasticity, is also proposed.
Functions for robustified estimators of the generalised ratio model are implemented by the iterative re-weighted least squares algorithm in R environment and illustrated using random datasets. Monte Carlo simulation confirms accuracy of the proposed estimators, as well as their computational efficiency. A comparison of the scale parameters between the average absolute deviation (AAD) and median absolute deviation (MAD) is made regarding Tukey's biweight function. The results with Huber's weight function are also provided for reference.
The proposed robust estimator of the generalised ratio model is used for imputation of major corporate accounting items of the 2016 Economic Census for Business Activity in Japan.
Estimation of Velocity Structures in the Grenoble Basin, France, Using Pseudo Earthquake Horizontal-to-Vertical Spectral Ratio from Microtremors
Authors: Ito Eri , Cornou Cécile , Nagashima Fumiaki , Kawase Hiroshi
Published: February 2021

Based on the diffuse field concept for a horizontal-to-vertical spectral ratio of earthquakes (eHVSR), the effectiveness of eHVSRs to invert P- and S-wave velocity structures down to the seismological bedrock (with the S-wave velocity of 3  km/s or higher) has been shown in several published works. An empirical method to correct the difference between eHVSR and a horizontal-to-vertical ratio of microtremors (mHVSR), which is called earthquake-to-microtremor ratio (EMR), has also been proposed for strong-motion sites in Japan. However, the applicability of EMR outside of Japan may not be warranted. We test EMR applicability for the Grenoble basin in France with plentiful microtremor data together with observed weak-motion recordings at five sites. We thereby establish a systematic procedure to estimate the velocity structure from microtremors and delineate the fundamental characteristics of the velocity structures. We first calculate the EMR specific for the Grenoble basin (EMRG) and calculate pseudo eHVSR (pHVSR) from EMRG and mHVSR. We compare the pHVSRs with the eHVSRs at five sites and find sufficient similarity to each other. Then, we invert velocity structures from eHVSRs, pHVSRs, and mHVSRs. The velocity structures from eHVSRs are much closer to those from pHVSRs than those from mHVSRs. We need to introduce a number of layers with gradually increasing S-wave velocities below the geological basin boundary from a previous gravity study because the theoretical eHVSR of the model with a large velocity contrast has larger peak amplitudes than the observed. The depth of the S-wave velocity of 1.3  km/s (Z1.3) shows a strong, linear correlation with the geological boundary depth. Finally, we apply our validated methodology and invert velocity structures using pHVSRs at 14 sites where there are no observed earthquakes. The overall picture of Z1.3 at a cross section in the northeastern part of the basin corresponds to the geological boundary.

Professionalization in Socialism : Architects and Architecture after 1945 in Hungary
Authors: Keller Márkus
Published: February 2021

In my study, I investigate architects’ search for their place in the new society and the history of their profession after 1945 in Hungary with the help of professionalization theories. Through statistics, memoirs, interviews, archival documents, laws and decrees, I seek to discover what kind of role architecture and architects played in the dictatorship of the 1950s and how that role changed in the Kádár system. In addition to external analysis, I place particular emphasis on how this change of role is reflected in the lifestory interviews and in the identity of the architects of the era.
Confidence Interventions: Do They Work?
Authors: Williams Ryan Thomas
Published: February 2021

The purpose of the present study was to investigate the effectiveness of different confidence enhancing techniques (Positive Self-Talk, Imagery, and Confidence Profiling) in amateur track and field athletes. Fifteen participants volunteered to take part in the study, five in each intervention group. A baseline measure using TSCI and SSCI has administrated prior to the intervention. Each athlete then completed a four-week intervention, completing the TSCI and SSCI again post-intervention. Results from a mixed model ANOVA yielded a significant difference in pre scores to post in each intervention, p < 0.05. Although no significant difference was found between groups, p > 0.05, meaning all groups were of equal effect. Despite not being statistically different, imagery improved scores the most. These results provide a protocol structure for psychologists and coaches to follow.

Authors: Kusma Verônica Venturini , Chiroli Daiane Maria de Genaro
Published: February 2021

The aim of this paper is to discuss and present definitions, benefits and changes of positions, which are related to the fourth industrial revolution era, 4.0 industry. The industry 4.0 concept is based on the integration of several innovative technologies which have been revolutionizing the way processes are performed in organizations. As in the industrial revolutions that occurred throughout history, 4.0 industry has caused impacts and changes in the current production model and work dynamics, as well as adaptations in labor systems. With the development of the fourth industrial revolution we have a new productive reality where everything within an industry will be connected to make the best decision regarding production, cost and safety. However, this transition from the current working model will require a great deal of learning and rapid worker training. Different types of jobs will be specifically impacted because of their nature, and these impacts depend on categories and the industrial sector itself. It is essential that we make an evaluation of the impacts that the 4.0 industry will have on work dynamics.

Published: February 2021

The purpose of this study is to investigate the best suitable pan sharpening method for CARTOSAT-2E satellite launched by ISRO (Indian Space Research Organisation). This satellite provides high resolution images that are being used for many urban applications such as mapping, feature extraction, facility management etc. The synthesized image using pan sharpening method enables users to take the combined advantage of the best available spatial and spectral resolutions. In this paper, various pan sharpening methods based on component substitution (CS) and Multi Resolution Analysis (MRA) are applied on the CARTOSAT-2E images and the resultant images are tested for their qualitative and quantitative performance. Qualitative analysis is carried out based on image blur and spectral distortion and quantitative evaluation is performed using image metrics by comparing the synthesized image with the original image. The results show that the High-Pass Filter (HPF) method offers the good spectral fidelity. However, due to its inherent stair-casing effect in the resultant image; modified-IHS followed by PRACS method is found to be preferable for automatic urban feature extraction from CARTOSAT-2E images.

Published: February 2021

Line to Ground (LG) and Line to Line (LL) faults are the two most frequently encountered faults in any power system network. For the purpose of designing advanced protection systems, detection of the location as well as the identification of the type of fault, from a remote location is of paramount importance. In this paper a Discrete Wavelet Transform based statistical analysis has been carried out to detect the fault type and location of LG and LL faults. IEEE standard 9 bus system has been considered for this purpose. Faults are made to occur in the load buses and outgoing currents from the generator buses are analyzed by Discrete Wavelet Transform (DWT) as these current waveforms are non-stationary in nature. Statistical parameters are calculated from the approximate and detail coefficients which have been derived from the DWT. Based upon these parameters, a rule set has also been made. Simulation work is performed with the help of MATLAB. Methods proposed here can be helpful for designing better protection schemes.

The main objective of this work is the application of a new architecture of genetic algorithms to the induction machine design in order to improve their performance. The latter is proposed by our research team based on modified crossing and mutation operators who have fixed values for conventional genetic algorithms. In addition, this version is characterized by a double loop and a random crossover. Firstly, to demonstrate the ability to locate the global optimum with this version algorithm a mathematical function was used. Then we approached the second phase which its application in real time to the induction motor optimized design problem. Knowing that, the machine is a highly coupled with multivariable system and constraints. Finally, the results obtained have been analyzed where we have found that satisfactory and can be declared that adaptation algorithm is effective in locating rapidly the region in which the global optimum exists in relation to the classical genetic algorithm.

Published: February 2021

The aim of this study is to evaluate the influence of the position of a DC/DC static converter between a source and a load with regard to the conducted EMC emissions measured on the source. An experimental model was established through the analysis of relevant stresses, such as the variation in the lengths of the source-converter, converter-load cables and the impact of the shield connection. Through this study, it was observed that the circuit was sensitive to too large variations in the capacities of common mode and of the link, and the results obtained make it possible to confirm the reality of the electromagnetic pollution of the static DC/DC converter "Buck" as a function of connections. The results of this research can be used in DC/DC network designs based on buck converters.

The purpose of this study is to improve the control performance of a Doubly Fed Induction Generator (DFIG) in a Wind Energy Conversion System (WECS) by using both of the conventional Proportional-Integral (PI) controllers and an Artificial Neural Network (ANN) based controllers. The rotor-side converter (RSC) voltages are controlled using a stator flux oriented control (FOC) to achieve an independent control of the active and reactive powers, exchanged between the stator of the DFIG and the power grid. Afterward, the PI controllers of the FOC are replaced with two ANN based controllers. A Maximum Power Point Tracking (MPPT) control strategy is necessary in order to extract the maximum power from the of wind energy system. A simulation model was carried out in MATLAB environment under different scenarios. The obtained results demonstrate the efficiency of the proposed ANN control strategy.

Published: February 2021

Geostatistics plays an important role for reserve estimation in mining industry. Geostatistical tools became popular because of its high degree of accuracy and time saving process for estimation. The uncertainty of geological deposit can be populated by geo-statistical tools. The limestone ore deposit was studied in this paper. The assay value of individual constituents of limestone ore i.e CaO, SiO2, Al2O3 and Fe2O3 were determined for a block by using Inverse Square Distance Weighting (ISDW) method. The average assay value of those individual constituents were 45.85, 15.94, 1.56 and 0.82 percentage respectively. The assay value of CaO was also estimated by two linear method of estimation i.e ISDW and Ordinary Kriging (OK). The assay value of CaO were determined 45.85 and 44.67 percentage respectively. The assay values were properly validated and concluded accordingly. The application of ISDW and OK were implemented to build the resource model together in order to assess the uncertainty of the deposit. Grade estimation by using different geo-statistical techniques are done by SURPAC mine planning software.

Federal Security Service in the national security system
Authors: Turkaeva Laura
Published: February 2021

In the context of the current political situation in the country, the relevance of scientific research is due to its extreme importance, seen through the prism of the theoretical and practical significance of law enforcement activities of the Federal security service at various historical stages, and its provision of national security. The scientific novelty of this work is formed from a complex of analytical characteristics of the Federal Security Service activi-ties and comes down to the fact that it presents the special aspects of the professional work of the Federal Security Service, in addition, a comparative assessment of legal norms is carried out. Due to the democratization of Russian society, significant changes are taking place in the law enforcement agencies system. The constitutional consolidation of human and civil rights and freedoms as basic values determines their supremacy in relation to public law values. We emphasize that the Federal Security Service is the leading central body in the system of executive power, whose activities to ensure national security are built taking into account the fundamental principles of legality, respect, observance of human and civil rights and freedoms, conspiracy, in a combination of overt and covert methods and means. We indicate our own position in understanding the essence and characteristics of national security.
Balance of private and public interests in the field of entrepreneurial activity during the period of taking measures to ensure the sanitary and epidemiological welfare of the population
Authors: Bibarov-Gosudarev Anton
Published: February 2021

The work is devoted to the issue of determining the balance of interests of the entrepreneurial community, society and state. We conduct a fairly detailed analysis of the reasons for the restrictions imposed due to the spread of new coronavirus infection COVID-19. We work on the concepts of “public interest” and “private interest”, we investigate the limits of restric-tions that the state has the right to impose in terms of entrepreneurial activity regulation. We substantiate the conclusions that the tasks of entrepreneur-ship’s state regulation indicate that state regulation is necessary not only for the state, but also for entrepreneurs themselves. And the introduction of re-strictions, despite all their painfulness, was beneficial in the long term for en-trepreneurs. We also emphasize that these restrictions are not always propor-tionate and adequate to the current conditions. In the course of the study, we conclude that the restrictions should be thoughtful, understandable and justi-fied, while the state should think about counter measures of support, since in fact, in the current situation, the entrepreneurial community shared with the state all the risks and severity of consequences from the complication of the sanitary and epidemiological situation in the country.

Método: Trata-se de um estudo transversal e quantitativo, com abordagem descritiva, realizado entre os meses de março e maio de 2016 com 124 médicos atuantes em uma maternidade pública de ensino do município de Fortaleza, Ceará, Brasil. As informações foram obtidas por meio do survey Hospital Survey on Patient Safety Culture (HSOPSC), Criado pela Agency for Healthcare Research and Quality (AHRQ), que avalia as percepções de profissionais em relação à segurança do paciente em 12 dimensões. Resultados: entre as doze dimensões avaliadas, uma apresentou taxa de resposta positiva acima de 75% (área fortalecida): aprendizado organizacional e melhoria contínua (80,4%), e abaixo de 50% (áreas com potencial de melhoria): as dimensões passagens de plantão/turno, transferências internas (45,96%) e frequência de eventos notificados (39,51%). Quanto a percepção geral sobre a segurança do paciente, necessita de melhorias na visão dos médicos. Conclusão: O estudo demonstrou a existência de uma cultura de segurança na instituição, mas com potencial de melhorias em algumas dimensões o que pode ser alcançado através do desenvolvimento de intervenções mais efetivas. Este tipo de investigação é útil pois serve como instrumento eficaz no planejamento, auxiliando os gestores nesta atividade.

Published: February 2021

Treatments in the field of facial aesthetic medicine are largely related to the discontinuity of the skin and are performed by both doctors and dentists. In the dentist's office, where such procedures are performed, as in any other therapeutic entity, the patient's rights apply, which are a guarantee of subjective treatment of the patient. They enable the patient in the situation of violation of patient's rights, dissatisfaction with the effects or occurrence of a complication or adverse event to refer the case to the appropriate authorities. The paper presents the basic rights of the patient, expressing the protection of his autonomy (freedom of will, awareness and knowledge) in terms of his own health.
Botulinum toxin and hyaluronic acid — the most common facial aesthetic medicine treatments — the economic aspect in terms of price in 2019 in Poland
Authors: Tomaszewski Mateusz
Published: February 2021

Introduction. The observed intensive quantitative growth of aesthetic medicine clinics on the market may lead to a lowering of the general price level, although nowadays the high quality of services is a factor that determines the choice of a surgery more often than a low price.Aim. Estimate of average prices of selected facial aesthetic medicine’s procedures in Poland in 2019.Material and Methods. 7 types of facial aesthetic medicine treatments with the use of botulinum toxin or fillers that were used in 112 clinics located in Poland in 2019 were taken for the analysis.Results. The highest prices for wrinkle reduction with botulinum toxin were in the Mazowieckie Voivodeship and the lowest in the Podlasie Voivodeship. Treatments with the use of fillers cost the least in Kuyavian-Pomeranian, and the most in Mazowieckie. The most expensive treatment among the examined was the correction of the shape of the lips - 910 PLN and the cheapest was the reduction of wrinkles around the eyes - 460 PLN.Discussion. Higher prices than average can be expected in provincial cities. This is often dictated by the level of service innovation and / or patient wealth. Sometimes offering lower prices than the average can be an effective way to attract customers.Results. Treatments with the use of fillers are more expensive than those with the use of botulinum toxin by almost half. Most surgeries offer services in the field of facial aesthetic medicine using botulinum toxin and / or fillers at comparable prices.

Nilem fish belongs to freshwater fish commodity that has been widely cultivation. Some factors influencing fish cultivation are good quality of feed, quantity, size, and shape. Quality feed works as a primary energy source as well as improves the digestive system of fish, with the expectation that the fish growth and health are optimal. Information concerning health status in cultivation Nilem has been used as a reference for improving cultivation methods and controlling disease attacks. The population and production of fish cultivation is experiencing serious problems due to infection from various types of pathogens. Therefore, a viable alternative is needed to prevent and overcome diseases by utilizing immunostimulant substances derived from synthetic substances that can increase the activity of non-specific immune defenses and stimulate antibiotic-forming organs in fish body. Immunostimulant is a substance that is capable of increasing the mechanism of non-specific immune response of fish one of them is by adding Chlorella vulgaris extract to the feed. This research objective is to determine the influence of Chlorella vulgaris supplementation on total blood albumin in nilem fish. This research was conducted by sampling method consisting of 5 treatments with further 4 replications. The treatments were feed supplementation of 0 g.kg-1, 2 g.kg-1, 3 g.kg-1, 4 g.kg-1, and 6 g.kg-1. Independent and dependent variables were used in this research; the independent variable was the dose of Chlorella vulgaris in the feed and the dependent variable was blood albumin concentration. The measuring of plasma albumin concentration was done using the Dyasis kit method with a spectrophotometer. The obtained data were then analyzed by ANOVA, followed by the Least Significant Difference (LSD) at the 95% confidence level if there is a real difference then followed by Tukey's test at the same confidence level. The results showed that the average value of serum albumin concentration of nilem fish from all treatments was between 4.2761 – 7.1826 g/dL. The normal albumin concentration was found in the treatment 4 g.kg-1 Chlorella vulgaris supplementation which was 4.77 g/dL. Meanwhile, the highest concentration was found from the supplementation of Chlorella vulgaris at 3 g.kg-1 feed which was 6.677 g/dL.

Coastal areas, being vulnerable to environmental problems, have one of the most frequent problems which are the change in the shorelines. Shoreline changes, namely abrasions, can cause problems such as land degradations or loss of land in a coastal zone. This problem occurs in many areas, one of which is Pontang Cape. This study aims to determine the distance and rate of shoreline changes that occured in the Cape and its surroundings, as well as explaining the analysis points based on similar studies that had been conducted. This research used ArcMap software and Digital Shoreline Analysis System (DSAS) toolset to determine the distance and rate of shoreline changes for 19 years (1999-2018). Based on the results, there were two shoreline segments where different phenomena of shoreline change took place, namely Banten Bay (accretion) and Pontang Cape-Lontar (abrasion). The most likely causes of changes in the shorelines are sediment runoffs from rivers that lead to bay and sediment transports that affect Banten Bay accretions, while sea sand mining and conversions of mangrove swamps into fishery ponds are factors affecting abrasions in Pontang Cape.Keywords: Abrasion, Accretion, Pontang Cape, Banten Bay, DSAS
