Structure of Koszul Algebra in Lie Algebra M_(3,1) (R)‹Šã –glã —_3 (R)
Abstract
In this research, we study the affine Lie algebra aff(3) of 12 dimension which is the semi-direct sum of the vector space of a matrix of 3x1 and Lie algebra of a matrix of 3x3. The research aims to prove the existence and structure of koszul algebras on the affine Lie algebra aff(3) . Since its Lie algebra is Frobenius then there exists a linear functional whose values in the matrix structure are not equal to zero. Such a linear functional is called a Frobenius functional. Furthermore, in this study, it is also given how to obtain the structure matrix, to calculate its determinants, and to choose the right Frobenius functional. The results obtained in this study are explicit formulas for the structure of the koszul algebra on 12-dimensional Lie affine algebra through induction in the symplectic form of its Frobenius functional. As a discussion material for further research, the results obtained can be developed to determine the structure of koszul algebra in affine Lie algebra of dimension n(n+1)

Analysis of the debate on the concept of the state and citizens in the BPUPK meeting treatise
No full textIn the learning of Pancasila and Civic Education, discussions about BPUPK are often attached to the debates about the formulation of Pancasila as the national principle. In fact, the debates in the BPUPK meeting did not only concern to the national principle, but also about the concept of the state and the citizen. This research aims to analyze how the debate over the concept of the state and citizen is in the treatise of the BPUPK meeting. This research used a qualitative approach with library research methods and qualitative data analysis techniques. The results of this research showed that the debate on the concept of the state was divided into two, namely the debate in the form of the state which is faced with the form of a unitary state, union state and state union, and the debate in the form of government which was faced with the monarchy and republic. Furthermore, the debate about citizens was also divided into two, namely the debate on citizenship for foreign descendants which debates whether or not to make foreign descendants as Indonesian citizens in the Constitution, and the debate on the rights of citizens that debates whether to include or not, the rights of citizens in the Constitution
The narration of religion on television, reconstruction of meaning and diversity
No full textThis paper aims to construct the diversity reality of the society that has been presented in the media reality of television. Television presents symbols that need to be interpreted critically. When humans perform critical interpretation consciously, the meaning of diversity will be comprehensively grasped. On the contrary, when television shows cannot be interpreted in a mature frame of mind, it will become a serious problem for society. One of the serious issues deals with the abundant religious shows in the month of Ramadan. Religious television programs are part of religion commodification. Religion became a cheap trade. Ironically, many people enjoyed the show and served it as a guide. In fact, what is shown on television has largely blinded the reality of humanity and distanced human beings from civilization
The end of print media?
No full textThe publication end of print media certainly remains some serious problems. First, the termination of employment for media workers. The layoff may target the workers who operate machines and or workers at the circulation section. The publication end of Republika print media has caused more than 200 people out of work. Of course, this is not a small number. In fact, the laid-off workers should hold and fulfill their family life needs. This means that there will be an extraordinary upheaval for media workers when the print newspaper edition closes. Second, the end of newspaper print editions causes many newspaper peddlers/sellers to be unemployed. This is a very sorry situation as they belong to low-income people who must lose their job. Their income is highly dependent on how many copies of the newspaper are sold. The sales of print newspapers are not profitable. When fewer print newspapers are in circulation and the people purchasing power is small, the more painful the life of newspaper sellers will be
Development of Adaptive MOOCs to Support Personalized Learning: Mixed Method Analysis
No full textThis study aims to explain the development of adaptive MOOCs that support personalized learning. This study was designed with a mixed method design of sequential explanatory type at the association level. Quantitative analysis used confirmatory factor analysis (CFA) (n = 110) and was deepened with qualitative analysis of the Miles and Huberman model. Quantitatively measured domains include accessibility, learning curriculum, competence, motivation, satisfaction, efficacy, and self-study. The domain was used as a reference for qualitative data mining through focus group discussions (FGD) involving lecturers and doctoral students (n = 25). The analysis results show that the curriculum domain and one of the motivational indicators should be removed because it did not meet the requirements after bootstrapping. The second running algorithm showed all valid and reliable variables. Some domains that significantly affect MOOC user satisfaction are efficacy, competence, and motivation. R square results showed 37% influenced by motivation, accessibility, efficacy, and self-study, and the rest influenced by other variables. In the qualitative analysis, 19 subcodes were found that were included in the three main codes. In conclusion, there is new information in the accessibility domain that expands quantitative data, including information on MOOCs, marketing traps, regulation, and dropouts. Meanwhile, what strengthens and deepens quantitative data is found in the information on metacognitive and personalized coding that strengthens the domain of efficiency, the domain of competence, which is strengthened by content, mentoring collaboration, and motivation reinforced by coding the user\u27s motivations and goals
