Abstract

Surakarta is one of the cities in Central Java which is known as the city of batik and a tourist destination area which is supported by tourist attractions in the form of various historical sites that have integrated with the culture of the local community. The arrival of tourists to various tourist destinations in Surakarta in addition to enjoying existing tourist objects is also to get souvenirs that have local uniqueness. Apart from hunting batik for souvenirs, many also hunt for distinctive T-shirts, especially for young tourists, because they are inspired like traveling to Bali and Jogja. To provide a new alternative in the form of t-shirts with designs that have local uniqueness, it is planned to partner with CV. Asta Saka Semesta which produces t-shirts, convection, and merchandising. Service methods in the form of training and assistance in making innovative designs for tourist souvenirs; lectures to increase knowledge about survival strategies in business; expansion of marketing through participation in exhibitions; documentation of product samples and procurement of shelves for product documentation that has been produced. The results are 5 innovative designs, namely the design of a tourist attraction patterned t-shirt combined with classic batik motifs, as well as the production process for tourist souvenirs, 2 t-shirt designers have increased their knowledge and skills in making designs to meet the needs of tourists.

Abstract

Dalam artikel ini dipelajari aljabar Lie affine Frobenius aff(2, R) berdimensi 6. Aljabar Lie aff(2, R) dapat didekomposisi menggunakan dekomposisi Levi menjadi aljabar Lie linear khusus semisederhana sl(2, R) berdimensi 3, subaljabar Lie komutatif R ⊂ R2 berdimensi 2, dan split torus T berdimensi 1 sedemikian sehingga aff(2, R) = sl(2, R) ⊕ R ⊕ T. Karena aljabar Lie sl(2, R) semisederhana maka bracket Lie-nya dapat dinyatakan sebagai [sl(2, R), sl(2, R)] = sl(2, R). Selanjutnya, misalkan g = R⊕T sehingga aff(2, R) = sl(2, R) ⊕ g. Diperoleh bahwa [sl(2, R), g] ⊆ g dan [g, g] ⊆ g. Dalam hal ini, g adalah solvable radical dari aff(2, R).Kata Kunci: Aljabar Lie affine, Aljabar Lie Semisederhana, Dekomposisi Levi

Abstract

In this paper, we study symplectic form on low dimensional real Lie algebra. A symplectic form is very important in classifying of Lie algebra types. Based on their dimension and certain conditions, there are two types of Lie algebras. A lie algebra with odd dimension endowed with one-form such that is called a contact Lie algebra, while a Lie algebra whose dimension is even and it is endowed with zero index is called a Frobenius Lie algebra. The research aimed to give explicit formula of a symplectic form of low dimensional contact Lie algebras and Frobenius Lie algebras. We established that a one-form associated to simplectic form determine a type of a Lie algebra whether a contact or a Frobenius Lie algebras.To clearer the main results, we give some examples of one-form and symplectic form of Frobenius and contact Lie algebras.

Abstract

The service partner is Mr. Aris Supriyadi's Batik Kartika Business, located in Bugel Hamlet, Tirtomoyo Village, Tirtomoyo District, Wonogiri Regency, which is facing the main problems of: 1) Low product innovation due to the lack of maximum development of batik designs that can contribute to competitiveness among similar products, 2) Lack of complete equipment that supports increasing the quantity and quality of production. The implementation of this activity program, using a mentoring and training approach; In this context, the training in question is to provide some knowledge of the batik production process, the development of designs that have local distinctiveness for seven tourist attractions, and transfer of experience in exhibiting regional superior products, especially batik as a promotional event and marketing improvement. The results of the activity are an increase in knowledge about design as one of the determinants of product competitiveness, and crafters have improved skills in making designs with local potential sources of ideas. Partners have been given additional equipment in the form of stoves for stamped batik, stamp tables, and equipment for boiling/removing wax in the form of kenceng. Improved marketing through assistance in the Wonogiren Batik Festival to commemorate the 82nd Anniversary of Wonogiri Square.

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).

Abstract

Family business has a key role in economic growth and labor. Entrepreneurship education(EE) is any activity that aims to inculcate the mindset or mindset about entrepreneurship, fostering the intention, attitude and competence of a person in developing his potential by realizing creative and innovative behavior. Objectives to be achieved in research are (1)to analyze the influence of family background variables on entrepreneurship intention. (2)Analyze the influence of entrepreneurship education from variable to entrepreneurship intention. (3) Analyze the influence of creativity variable on entrepreneurship intention. (4)To analyze the effect of family background variables, entrepreneurship education and creativity together on the intention of entrepreneurship. This research is a descriptive research using quantitative approach. The location of this research is at Sahid University of Surakarta with total of 100 respondents. Data collection used in this research is questionnaire, observation and literature. The results obtained that the three independent variables are family background, entrepreneurship education and creativity positively influences entrepreneurship intention. Hypothesis testing using t test shows that all independent variables have significant less than 0.05. Then through the F test known that the three independent variables proved to have a significant influence together on entrepreneurship intention. The authors suggest that future research is needed approaches in Entrepreneurship education for others college students or university.

Abstract

In this paper, we study notion of the Lie algebra  of dimension 6. The finite dimensional Lie algebra can be expressed in terms of decomposition between Levi subalgebra and the maximal solvable ideal. This form of decomposition is called Levi decomposition. The work aims to obtain Levi decomposition of Frobenius Lie algebra of dimension 6. To achieve this aim, we compute Levi subalgebra and the maximal solvable ideal (radical) of  with respect to its basis. To obtain Levi subalgebra and the maximal solvable ideal, we apply literature reviews about Lie algebra and decomposition Levi in Dagli result. For future research, decomposition Levi for higher dimension of Frobenius Lie algebra  is still an open problem.

Abstract

Corn farming on the island of Java plays a crucial role in meeting the nation's food needs. However, variations in land conditions across provinces in Java result in differing production levels. This disparity affects the supply of corn in the market, and the selling price often does not align with farmers' expectations. Therefore, this article aims to determine the optimal timing for distributing corn, particularly on the island of Java, using the Euclidean algorithm. The Euclidean algorithm is used to calculate the greatest common divisor (gcd), which in turn is applied to determine the least common multiple (lcm). The lcm results can serve as a reference for identifying the best time to sell corn to prevent price declines. Additionally, a comparison of production levels across provinces is presented to help corn farmers understand when and where to distribute their produce to achieve maximum profit.
