Retrospective analysis of the problem of introducing convicts to the values of art
Authors:   FSI “Research Institute of the Federal Penitentiary Service of Russia”, Vologda, Zautorova Elvira V.
Published: January 2022

The problem of socialization of the individual in the contradictory conditions of the country is one of the most urgent for modern Russia. The socio-cultural crisis has affected all the main spheres of our existence, led to the loss of many values, and affected the spiritual and moral sphere. In these conditions, it is important to know which deep regulators, that is, the motives of human actions – goals, traditions, emotions, needs and values drive the behavior of the individual. It seems to us that the active introduction of convicts to various types of art in the correctional and educational process will help to form positive value orientations of offenders, will contribute to their more successful moral correction. Meanwhile, the analysis of penitentiary practice reveals contradictions between the spiritual and moral potential of art and its lack of demand in the correctional process of penitentiary institutions, the presence of rich experience in moral and aesthetic education of the individual and the lack of technology for its implementation in places of deprivation of liberty, the insufficiency of modern professional training of specialists for the penal system. Therefore, problems related to the study, identification, description and understanding of general and specific ways, adequate methodological techniques that contribute to the formation of moral value orientations of convicts by means of art are relevant for science and practice. Works of art are not mechanically transformed into human actions, but undergo rethinking and selection in his moral experience, filling it with socially valuable content, contribute to the versatile development of personality, develop an aesthetic attitude to reality. A retrospective analysis of the introduction of convicts to the values of art will contribute to search new ways to correct the personality based on the principles of humanism and democracy.
Positive-functional potential of public organizations in the emerging network society (a conflictological aspect)
Authors:   Russian Academy of national economy and public administration under the President of the Russian Federation, Nikovskaya Larisa I.
Published: January 2022

The article shows that in the context of the formation of a digitalnetwork society, the phenomenon of polysubject is growing, which leads to the transition to the model of public administration through communities based on the management dilemma “leadership-acceptance”, which limits the possibilities of the hierarchical-bureaucratic rule and turns out to be more effective. All these reasons are due to qualitative changes in the system of civil society: the sharply increasing emancipation of the individual from the state, the reduction of the space of direct command influence of the latter, the vigorous development and complication of horizontal social ties and the plexus of diverse civil institutions and movements into a holistic network. For public policy, the task of optimizing the interaction of the authorities and representatives of civil associations, strengthened by digital network capabilities that allow the formation of centers of social force through the consolidation of interest groups and public opinion, becomes important. The search for "consent zones," based on building and creating a balance of public interests, calls for conflictual diagnostic tools and the resolution of problematic points of interaction. A satisfactory and comprehensive solution to the problem requires a wide range of conflict actions - from negotiation and mediation, legislative initiatives and public hearings, expertise and monitoring, to lawsuits and proceedings, and sometimes acts of civil disobedience. All these actions require a conflictological competence, which accustoms representatives of the public sector to greater professionalism, culture of interaction with state bodies, providing a comprehensive diagnosis of the conflict situation and a wide range of technologies to influence its solution, and state representatives focus on recognizing alternative positions, respectful dialogue with the public and developing an appropriate legal framework for a long partnership with the nonprofit sector. These trends in the style of public policy have been demonstrated on the strategy of behavior of the women's public organization “Petersburg Egida” in solving the conflict situation related to non-payment of maternity funds for pregnant women, as well as for the care of young children.
Comparative analysis of speech etiquette in modern Russian and Chinese
Authors:   Southwest university in Chongqing, Wang Liancen
Published: January 2022

The article is devoted to a comparative analysis of speech etiquette in the modern Russian and Chinese languages; it is noted that an important feature of speech etiquette is a reflection of the national culture and national specifics of speech behavior. Speech etiquette includes communicatively significant meanings: social, international, emotional and evaluative, and identifying and understanding these meanings is impossible without taking into account the national specifics of etiquette rules. The article examines in detail the formulas of speech etiquette related to the situations of address, gratitude, apology and request in Russian and Chinese, analyzes the system of kinship terms in Chinese, which is more detailed compared to the Russian language, provides the results of analyzing the use of proper names in speech formulas. The article considers the choice of lexical means in address, request and gratitude, depending on the characteristics of the communicative situation (the relationship between the addressee and the addressant, the communicative situation, the method and purpose of communication, the tone of communication, etc.). The author gives examples of various speech scenarios in Chinese communication, analyzes the tendency to euphemizing speech in Chinese etiquette formulas, and concludes that a comparative analysis of speech etiquette in modern Russian and Chinese helps to increase cultural awareness in the use of language and understanding that the peculiarities of speech interaction of the communicants require attention not only to the linguistic structures themselves, but also to the specifics of speech behavior and the associated pragmatics of communication.
Russian and Chinese proverbs: linguocultural aspect of commercial relations
Authors:   Siberian federal university, Krasnoyarsk, Lesinskaya Anastasiya K.
Published: January 2022

The article is devoted to representing trade and monetary relations in the Russian and Chinese proverbs. The structural components that make up the frame scenario of the concept “trade” are identified in these texts. Its value component characterizes the participants in the trade situation and the subjects of market relations. The comparison of the two linguocultures allows us to describe common semantic groups and those specific to Russian proverbs, such as Profit, Loss and Spending. The article demonstrates that the scenario of the concept “trade” in Russian and Chinese proverbs and sayings is presented as a multicomponent situation, denoted by the lexemes trade and bargaining in Russian and 买卖 mǎimai, 生意 shēngyi, 生意经 shēngyìjīng in Chinese. The Chinese texts are dominated by the nominative lexical expression of the participants in the situation, while the Russian paremics are dominated by the predicate: the four nominations of the seller, three nominations of the buyer and seven verbs in the Chinese paremics are contrasted with two nominations of the seller and twelve verbs in the Russian texts. The article concludes that a comparison of the seller's images in the two linguistic cultures shows a different degree of detailing their ethical characteristic – honesty. The Russian texts contain the ugly recommendation to “trade in truth”, while the Chinese texts contain a figurative recommendation to trade honestly, expressed in a negative construction (“one should not trade dishonestly”), and directly and figuratively indicating the cunning, deceitful nature of the seller, the image of the buyer in Russian texts is endowed with predominantly negative connotations. In Chinese proverbs, on the contrary, the buyer is an equal participant in the buying and selling situation, defending the favorable conditions of the deal.

Organization of flash mobs and mass holidays: socio-pedagogical aspect
Authors:   Kokshetau University named after A. Myrzakhmetov, Teslenko Aleksandr N.
Published: January 2022

The article is devoted to the analysis of peculiarities of cultural and leisure activity of rural youth. The need for a scientific analysis of the phenomenon of a youth holiday and especially its modern forms, for example, such as a flash mob, concerns the importance of festive culture in its modern forms for the cultural socialization of youth and the spiritual development of society. In the conditions of public consciousness modernization, the holiday as a form of cultural and leisure activity has a special functional burden in the system of free time for young people, primarily in line with the pedagogization of youth culture. However, this problem in modern socio-pedagogical literature is not deeply disclosed. The article justifies the author's position considering youth as an object of cultural and leisure influence from the point of view of its value-orientation attitude to leisure. Young people as an object of cultural and leisure influence are considered from the point of view of their value-orientation attitude to leisure. The analysis of the socio-cultural situation in the field of youth leisure of rural youth shows the transformation of traditional forms of leisure and the emergence of new – innovative technologies for youth leisure. The empirical material shows the educational potential of such an innovative technology for organizing youth leisure as a flash mob. Flash mob – a pre-planned mass action in which a large group of people appears in a public place, performs previously agreed actions according to the scenario and then breaks up. The most promising ones in educational practice are collective flash mobs, primarily song and dance, which do not take much time, in rare cases require large-scale training and can be used to work with almost all educational tasks. The author describes in detail the technological process of preparing and holding a flash mob as a mass youth holiday. The pedagogical effect of the mass youth holiday is proved, which is manifested in the development of group interaction skills and the self-organization of the youth association. Flash mob actions contribute to the development of active recreation, the manifestation of emotions in activities, the improvement of communication skills (due to involvement in the joint activity), self-approval in a socially approved type of activity.
Histórias entrelaçadas

O artigo tem por objetivo apresentar um panorama histórico das exposições de arte africana realizadas no MASP bem como tecer algumas considerações sobre as coleções africanas presentes em seu acervo. Apesar de o Museu de Arte de São Paulo ser reconhecido por sua coleção de arte europeia, essa instituição sediou e também organizou exposições de arte africana, além de ter constituído coleções. As exposições de arte africana realizadas no MASP podem ser entendidas basicamente, mas não exclusivamente, a partir de três perspectivas distintas: aquelas que respondiam a interesses privados, como é o caso da mostra Arte Negra (1953) e também daquela que exibiu a coleção africana do Bank Boston em 1976; as relacionadas à política de aproximação entre Brasil e África durante a ditadura militar no país, como é o caso de Arte Tradicional da Costa do Marfim (1974) e Arte Contemporânea do Senegal (1981); aquelas que exploravam a herança dos africanos no Brasil e estavam apoiadas na tese de fluxo e refluxo do tráfico de escravos, de autoria de Pierre Verger, cuja maior representante é África Negra (1988).

Forecasting the Oil Volatility Index Using Factors of Uncertainty
Authors: Delis Panagiotis , Degiannakis Stavros , Giannopoulos Konstantinos
Published: January 2022

The oil volatility index (OVX) has attracted the attention of investors, as oil prices have been subject to high degrees of variation in the last few decades, and investors would therefore benefit from obtaining accurate forecasts of OVX. In this paper, we aim to develop models that can accurately generate OVX forecasts. The contribution of our study to the literature lies in the incorporation of different factors that reflect uncertainty as potential drivers of OVX. For example, implied volatility (IV) indices, such as the VIX and GVZ are examined. Apart from the inclusion of IV indices, we investigate whether other uncertainty indicators play a significant role in generating OVX forecasts. Our results show that the predictive ability of the models is not enhanced by the inclusion of most of the aforementioned factors of uncertainty, with the single exception of the U.S. economic policy uncertainty index, which seems to improve the forecasting ability of a simple model that focuses on the OVX as a target variable.

Authors: Moonma Jitlada , Kaweera Chittima
Published: January 2022

The present study aims to explore critical thinking from EFL Thai students’ perspectives in collaborative writing activity. The subjects were 32 second-year English major students composing paragraph writing in the Writing II course. They were divided into three groups based on their English proficiency: advanced, intermediate, and novice, and data was collected using quantitative and qualitative approaches. The critical thinking skills questionnaire was utilized to collect quantitative data, and the results were analyzed using Mean and Standard deviation. For qualitative data, an interview was used to collect critical thinking skills practice of six students randomly selected. The quantitative results revealed that the highest critical thinking skills practice was found in analyzing (Mean=3.47, SD=1.15), followed by evaluating (Mean=3.44, SD=1.27), and creating (Mean=3.34, SD=.03), respectively. For qualitative results, it was found that the students in the high level of English proficiency group reported they practiced critical thinking by analyzing, evaluating, and creating. They produced a new sentence and a paragraph, selected the best ideas, and categorized the supporting details based on information and ideas from peers. Regarding intermediate and novice level groups, they reported identically that they frequently practiced analyzing and evaluating. Analyzing and assessing were two critical thinking abilities that were commonly utilized. They have to do with comparing and choosing content, as well as elements of arguments and supporting statements. As a result, collaborative writing appeared to promote pupils to use critical thinking skills when writing.
Old but Gold: Secondary School Students’ Communication Attitude Scale
Authors: BOYRAZ Serkan
Published: January 2022

Communication as a skill is not something new; however, it has become much more important than ever before as the way and with whom we communicate have changed. That is why educators need to have valid and reliable tools to understand how this skill is perceived by students. This study aims to provide a valid and reliable secondary school students’ communication attitude scale (SSSCAS). A draft form for the scale was prepared with 32 items depending on the relevant literature and reviewed by experts in the field. The revised form was applied to 397 students at a state secondary school in Aksaray city of Turkey in the 2020-2021 academic year. First, explanatory factor analysis that tests construct validity was carried out and three items were extracted from further analysis due to insufficient factor loadings. The remaining 29 items are placed under four sub-dimensions called openness to communication, body language and preferences, self-confidence, and obstacles. The structure was tested through confirmatory factor analysis and the validity of the scale with the four sub-dimensions was found to be appropriate. The Cronbach’s alpha values of all sub-dimensions and the scale were above the required level. As a result, the developed scale is a valid and reliable scale to assess communication attitudes of secondary school students.

Published: January 2022

Daily exposure to a number of xenobiotics is the major contributing factor to liver injury. The present study investigated the mechanism of hepatoprotection by glycyrrhizin, curcumin and cinnamon in two distinct models of hepatotoxicity i.e., by using Concanavalin-A (ConA) and Acetaminophen (APAP). For this evaluation, balb/c mice were pretreated with glycyrrhizin (200 mg/kg i.g.), curcumin (100 mg/kg i.g.) and cinnamon (200 mg/kg i.g.) extracts for 14 days followed by administration of ConA (15 mg/kg i.v.) and APAP (200 mg/kg i.p.) for 8 hours. At the end of the experiment, mice were dissected and blood and liver samples were collected for biochemical and histopathological analysis. Statistical analysis by using one-way ANOVA followed by DMR test was performed for the significance of results. The results showed that pre-treatment of glycyrrhizin, curcumin and cinnamon ameliorated the damaging effects of ConA and APAP on the liver as indicated by the serum transaminase enzymes and total protein levels. In addition, ConA and APAP exerted severe damage on liver tissues as confirmed from the histopathological analysis. However, glycyrrhizin, curcumin and cinnamon prevented liver injury, possibly through antioxidant mechanism. In conclusion, glycyrrhizin, curcumin and cinnamon possessed antioxidant properties with therapeutic potential in liver injury related to oxidative stress.

The Impact of Total Bank Assets, Income Diversification, and Financial Inclusion on the Stability of Islamic Commercial Banks in Indonesia With a Moderating Variable for the 2014-2019 Capital Buffer
Authors: Putrie Baby Ayu Bellya , Mappanyukki Ratna
Published: January 2022

For the five-year period 2014-2019, to determine and empirically demonstrate the influence of total bank assets on the stability of Islamic commercial banks in Indonesia, with the moderating variable of capital buffer. Sample size was determined using a purposive sampling approach, which included eight Islamic Commercial Banks. Using Moderated Regression Analysis to test hypotheses (MRA). As a result of these findings, it can be concluded that Islamic commercial banks in Indonesia are more stable if they have more diverse sources of income and greater financial inclusion. Islamic commercial banks in Indonesia's capital buffer can moderate the impact of income diversification on stability with the type of moderation generated by pure moderator, which indicates that stability can be improved. This is despite the fact that Islamic Commercial Banks' capital buffers are unable to counteract the negative effects of total assets and financial inclusion on their stability.

Cryptosporidium parvum is one of the major causes of neonatal calf diarrhoea resulting in reduced farm productivity and compromised animal welfare worldwide. Livestock act as a major reservoir of this parasite, which can be transmitted to humans directly and/or indirectly, posing a public health risk. Research reports on Cryptosporidium prevalence from the east Mediterranean region are scarce with even less originating from Cyprus. This study is the first to explore occurrence of Cryptosporidium spp. in young dairy calves on the island. A total of 242 faecal samples were collected from 10 dairy cattle farms in Cyprus, all of which were screened for Cryptosporidium spp. using nested-PCR amplification targeting the small subunit of the ribosomal RNA (18S rRNA) gene. The 60 kDa glycoprotein (gp60) gene was also sequenced for the samples identified as C. parvum positive to determine the subtypes present. Occurrence of Cryptosporidium was 43.8% (106/242) with at least one positive isolate in each farm sampled. Prevalence per farm ranged from 20¬‒64%, while C. bovis, C. ryanae and C. parvum were the only species identified. Amongst those, the latter was the predominant species, representing 51.8% of all positive samples. Four zoonotic subtypes were identified – IIaA14G1R1, IIaA15G1R1, IIaA15G2R1 and IIaA18G2R1. IIaA14G1R1 was the most abundant; representing 48.2% of all C. parvum positive samples and was also the most widespread. This is the first report of zoonotic subtypes of C. parvum circulating in Cyprus. These results highlight the need for further research into the parasite focusing on its diversity, prevalence, host-range and transmission dynamics on the island.

Liquid biopsies are an integral part of the diagnosis of cancer. Here, we have extended previous validation studies of a new targeted NGS panel to include the detection of copy number amplifications (CNAs), fusions, and exon skipping variants. Detection of these gene classes included specimens from clinical and healthy donors and cell lines (fusions: ROS1, EML4-ALK, NTRK1), (exon skipping: MET exon 14), and (CNAs: HER2, CDK6, EGFR, MYC and MET). The limit of detection (LOD) for fusion/skipping was 42 copies (QC threshold = 3 copies) and was verified using 3 additional fusion/skipping variants. LOD for CNAs was 1.40-fold-change (QC threshold = 1.15-fold change) and was verified with 3 additional CNAs. In precision studies, all fusion/skipping variants were detected in all runs and all days of testing (n=18/18; 100%); average CV for repeatability was 20.5% (range 8.7% - 34.8%), and for reproducibility was 20.8% (range 15.7% - 30.5%). For CNAs, 28/29 (96.6%) copy gains were detected. For CNAs, average CV of 1.85% (range 0% to 5.49%) for repeatability and 6.59% (range 1.65% to 9.22%) for reproducibility. The test panel meets the criteria for being highly sensitive and specific and extends its utility for the detection of clinically relevant variants in cancer.
Influence of Fly Ash Denitrification on Properties of Hybrid Alkali Activated Composites
Authors: Procházka Lukáš , Boháčová Jana , Vojvodíková Barbara
Published: January 2022

This article deals with the possibility of partial replacement of blast furnace slag with fly ash after denitrification by the Selective Non-Catalytic Reduction (SNCR) method in alkali-activated materials. In the experiment, the basic physical-mechanical properties and durability properties were tested, the hydration reaction was monitored in a calorimeter and infrared spectroscopy was performed. Results were compared between mixtures prepared with fly ash without denitrification and also with reference mixture based only on alkali-activated blast furnace slag. The basic result is the finding, that hybrid alkali-systems with fly ash after denitrification show similar trends as hybrid alkali-systems with fly ash without denitrification. The significant effect of fly ash is manifested especially in terms of resistance to freeze-thaw. The reactions in the calorimeter show a slower development of reactions with increasing replacement of slag by fly ash. In the case of testing resistance to leaching in demineralised water, a decrease of flexural strength was found, which corresponds to the conclusions of strength testing, that long-term deposition of bodies in water causes deterioration of mechanical properties.
Generalizations of the R-Matrix Method to the Treatment of the Interaction of Short Pulse Electromagnetic Radiation with Atoms
Authors: Schneider Barry , Hamilton Kathryn R , Bartschat Klaus
Published: January 2022

Since its initial development in the 1970’s by Phil Burke and his collaborators, the R-matrix theory and associated computer codes have become the de facto approach for the calculation of accurate data for general electron-atom/ion/molecule collision and photoionization processes. The use of a non-orthonormal set of orbitals based on B-splines, now called the B-spline R-matrix (BSR) approach, was pioneered by Zatsarinny. It has considerably extended the flexibility of the approach and improved particularly the treatment of complex many-electron atomic and ionic targets, for which accurate data are needed in many modelling applications for processes involving low-temperature plasmas. Both the original R-matrix approach and the BSR method have been extended to the interaction of short, intense electromagnetic (EM) radiation with atoms and molecules. Here we provide an overview of the theoretical tools that were required to facilitate the extension of the theory to the time domain. As an example of a practical application, we show results for two-photon ionization of argon by intense short-pulse extreme ultraviolet radiation

Teknologi beton selalu mengalami perkembangan yang lebih dinamis, beton ringan memadat mandiri (Light-weight Self Compacting Concrete) adalah salah satu beton yang dikembangkan. Beton ini terbuat dari agregat ringan yang dalam proses pemadatannya tidak membutuhkan alat penggetar (vibrator). Agregat ringan alami yaitu agregat yang diperoleh dari bahan-bahan alami seperti batu apung, skoria, atau tufa dan agregat buatan adalah agregat yang dibuat melalui peroses pemanasan seperti tanah liat, abut terang, abu sabak, dan batu lempung. Untuk meningkatkan workability pada beton ringan ini, maka digunakan penambahan superplasticizer jenis viscocrete sehingga diharapkan beton segar mudah mengalir dan melakukan pemadatan mandiri. Dalam penelitian ini mengamati serapan akibat penambahan kadar viscocrete. Kadar viscocrete yang digunakan ialah 1,5%; 1,75%; 2%; dan 2,25%. Benda uji yang digunakan untuk pengujian serapan adalah silinder berukuran diameter 7,5 cm dan tinggi 15 cm.

Seiring dengan perkembangan zaman, manusia melakukan pergerakan dari satu tempat ke tempat lain untuk memenuhi kebutuhan setiap individu, seperti bekerja, sekolah, belanja, dan masih banyak lagi. Setiap pergerakan yang ditimbulkan menyebabkan kemacetan, kelambatan, kebisingan, serta polusi udara, sehingga dilakukan perencanaan transportasi menggunakan MAT (Matrik Asal Tujuan) dengan pemodelan transportasi. Penelitian ini bertujuan untuk mencari nilai parameter β menggunakan model Gravity dengan metode Entropi Maksimum dan fungsi hambatan Eksponensial Negatif. Penelitian ini dilakukan di Kabupaten Sukoharjo yang dimana termasuk dalam bagian karesidenan Kota Surakarta. Selain itu, pembagian zona dilakukan berdasarkan jumlah kecamatan yaitu 19 zona internal dan 12 zona eksternal. Estimasi MAT ini dilakukan menggunakan model Gravity dan dibantu dengan program EMME/3. Model Gravity ini terdapat nilai parameter β yang berfungsi sebagai penentu besarnya nilai sebaran pada tiap zona. Metode yang digunakan untuk mencari nilai parameter β menggunakan metode kalibrasi Newton-Rapshon. Nilai arus lalu lintas yang dihasilkan akan dibebankan pada pembebanan User Equilibrium yang menghasilkan volume lalu lintas pada tiap ruas jalan, yang selanjutnya digunakan untuk menghitung tingkat validitas menggunakan koefisien determinasi (R2). Hasi dari pemodelan menunjukkan uju validitasnya sangat tinggi yaitu nilai R2 sebesar 0,803 sehingga dinyatakan bahwa arus lalu lintas hasil pemodelan mendekati sama dengan arus lalu lintas hasil traffic count, dan besaran nilai parameter β dari perhitungan Kalibrasi Newton-Raphson sebesar 0,070 yang dihitung menggunakan program Miscrosoft Excel. Sedangkan estimasi pergerakan dengan model Gravitysebesar 16366 smp/jam dengan total pergerakan terbesar diasilkan dari zona eksternal menuju ke zona eksternal sebesar 10909 smp/jam (66,68%).

Pembangunan infrastruktur di Indonesia saat ini berkembang pesat diikuti dengan meningkatnya kebutuhan beton. Beton merupakan komponen struktur yang dominan dalam konstruksi.Penggunaan beton dalam dunia konstruksi tidak hanya digunakan pada bangunan di darat tetapi juga pada bangunan air. Mutu dan durabilitas beton menjadi faktor penting yang harus diperhatikan. Beton dituntut memiliki kemampuan untuk bertahan pada kondisi dimanapun selama jangka waktu yang telah direncanakan. Jumlah pori pada beton mempengaruhi durabilitas beton. Jumlah pori yang semakin banyak pada beton menyebabkan permeabilitas dan serapan meningkat sehingga menyebabkan kuat tekan dan durabilitas menurun. Beton Bubuk Reaktif adalah beton yang dikembangkan menggunakan teknik perbaikan mikrostruktur dengan menghilangkan agregat kasar, menurunkan rasio air semen dan menambahkan material pozzolan. Silica fume merupakan material pozzolan yang berukuran sangat kecil yang dapat mengisi rongga dalam campuran beton dan akan memperkecil ukuran pori dalam pasta semen, sehingga dapat mengurangi permeabilitas beton. Kajian ini bertujuan untuk mengetahui pengaruh substitusi variasi silica fume 0%; 5%; 10%; 15%; 20% dan 25% pada beton bubuk reaktif terhadap nilai serapan CO2. Metode penelitian yang digunakan adalah metode eksperimental dengan benda uji beton silinder berukuran tinggi 15 cm dan diameter 7,5 cm dan berjumlah 18 buah. Pengujian serapan CO2 dilakukan dengan cara merendam benda uji ke dalam larutan karbonat 4% selama 10+0,5 menit dan 24 jam kemudian menimbang benda uji dalam keadaan SSD dan membandingkan dengan berat kering ovennya. Hasil dari penelitian ini adalah penambahan silica fume dan penggunaan faktor air semen yang rendah menyebabkan permeabilitas menurun sehingga nilai serapan CO2 menurun. Nilai serapan CO2 terendah yaitu pada kadar substitusi silica fume 15%, dimana dapat menurunkan serapan beton hingga 83,57% dalam perendaman selama 10+0,5 menit dan menurunkan serapan beton hingga 71,76% dalam perendaman selama 24 jam.

Penggunaan beton normal memerlukan banyak waktu dan tenaga. Maka dari itu dibuat alternatif pengganti beton normal yaitu beton Self Compacting Concrete (SCC), namun penggunaan beton SCC meningkatkan penggunaan semen yang akan melepaskan CO2 ke udara sehingga dibutuhkan senyawa tambahan untuk mengurangi kadar semen. Berdasarkan hal tersebut digunakanlah fly ash sebagai bahan tambah. Ukuran fly ash sangat kecil sehingga mampu mengurangi ruang antar agregat dan mampu meningkatkan nilai kuat tekan. Beton High Volume Fly Ash Self Compacting Concrete (HVFA-SCC) memiliki kadar fly ash lebih dari 50%. Penelitian ini akan menganalisis nilai kuat tekan, kuat tarik belah, dan modulus elastisitas akibat penambahan kadar fly ash sebesar 50%, 60%, dan 70% pada beton SCC terhadap beton normal. Hasil pengujian yang didapatkan, yaitu nilai kuat tekan beton normal dan beton dengan kadar fly ash 50%, 60%, dan 70% adalah 30,09 MPa, 29,80 MPa, 26,97 MPa, dan 21,69 MPa. Nilai modulus elastisitas yang didapatkan adalah 25100,38 MPa, 25023,94 MPa, 24139,28 MPa, dan 22354,94 MPa, dan Nilai kuat tarik belah yang didapatkan adalah 3,04 Mpa, 2,24 MPa, 1,79 MPa, dan 1,38 MPa.
