Abstract

Many games are related to Maths, such as bridge card games, dominoes, chess, NIM, and many others. For example, the NIM game is a strategy game played by two players or two teams in which each player or team takes turns taking at least one object with certain rules. Winning the game depends on how many objects are available and who plays first. In this article, we will present the NIM Maxima game. In this NIM game, the concept of Mathematics that will be used is number theory to determine a strategy to win the game.

Abstract

This research aims to identify the algebraic properties of the Chinese Remainder Theorem or CRT. Chinese Remainder Theorem is an ancient mathematical theorem that allows the solution of a system of simultaneous equations with different modules and allows the reconstruction of integers within a certain range of remainders modulo to relatively prime modulo. The method used in this research is literature study. This theorem allows for efficient processing and manipulation of integers with very large sizes. The proof of the theorems in Chinese Remainder Theorem is also presented in this research.

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

In this paper, we study the five-dimensional nonstandard Filiform Lie algebra and their basis elements representations. The aim of this research is to determine the basis elements of five-dimensional nonstandard Filiform Lie algebras representation in the form of  real matrices. The method used in this study is by following Ceballos, Núñez, and Tenorio’s work. The results of this study are five real matrices  as the realization of the basis elements of the five-dimensional nonstandard Filiform Lie algebra. We also discuss some results relate to five-dimensional nonstandard Filiform Lie algebra’s properties. The five-dimensional nonstandard Filiform Lie algebra is always nilpotent. For further research, it can be extended to five classes of Filiform Lie algebra, both standard and nonstandard with six dimensions. Moreover, it can be computed their split torus such that their direct sums are Frobenius Lie algebras.

Abstract

Peanut production on alluvial soil faced challenges due to low soil fertility. The application of soil amendments such as bioactive compost charcoal (BCC) was necessary to improve alluvial soil fertility. The aim of the study was to assess the effect of rice husk BCC application on the agronomic characteristics of peanut in alluvial soil. The research was conducted using a Completely Randomized Design (CRD) and analyzed using the F-test and Tukey's test at 5% significance level. The study design included 4 samples and 6 treatment levels: d1 (20 g/polybag), d2 (40 g/polybag), d3 (60 g/polybag), d4 (80 g/polybag), d5 (100 g/polybag), and d6 (120 g/polybag). The observation variables included plant height, number of branches, number of pods, pod wet weight per plant, and pod dry weight per plant. The data analysis results showed that the application of BCC had a significant effect on the agronomic characteristics of the peanut plants. The application of BCC at a dose of 120 g/polybag showed the best results and was recommended for use on alluvial soil with crop yield of of 31.72 g fresh pod or 24.86 g dry pod weight. Keywords: Agronomic characteristics, Alluvial soil, Bioactive compost charcoal, Peanut, Rice husk.

Abstract

Aljabar Lie su(N) mempunyai kompleksifikasi sl(N,C). Dengan kata lain, suNC≅sl(N,C). Dalam artikel ini, dipelajari representasi aljabar Lie su(N) dan sl(N,C) khususnya untuk N=2 yang direalisasikan pada ruang vektor polinom homogen kompleks dua variabel berderajat dua. Tujuannya adalah untuk mengkonstruksi representasi sl(2,C) dari representasi su(2) dan  membuktikan bahwa representasi yang diperoleh bersifat unitar dan tak tereduksi. Selanjutnya, karena grup Lie dari  su(2) bersifat simply connected maka representasi su(2) dapat dikonstruksi dari grup Lie-nya. Di sisi lain, karena su2C≅sl(2,C) maka representasi dari sl(2,C) dapat dikonstruksi melalui perluasan linear-kompleks dari representasi su(2) dan hasilnya dapat dinyatakan dalam bentuk operator linear.

Abstract

In this paper, we study low-dimensional Filiform Lie algebras. Specifically, three-dimensional standard Filiform Lie algebras and five-dimensional non-standard Filiform Lie algebras. The classification method was given in the following stage. For given a low-dimensional Filiform Lie algebra, we compute its second centre. We showed that three-dimensional Filiform Lie algebra-called Heisenberg Lie algebra-is type ???? and ????+ as well. On the other hand, for ????≥3, the standard Filiform Lie algebras are type ???? but not type ????+. In this case, we give a concrete example of case five-dimensional Heisenberg Lie algebra. Moreover, we proved that five-dimensional non-standard Filiform Lie algebra is type ???? but not type ????+. It is still an open problem to classify types ???? and ????+ for the general case of non-standard Filiform Lie algebra of dimension ≥6.

Abstract

In the present paper, we study some properties of the Heisenberg Lie algebra of dimension . The main purpose of this research is to construct a real Frobenius Lie algebra from the Heisenberg Lie algebra of dimension . To achieve this, we exhibit  how to compute the derivation of the Heisenberg Lie algebra by following Oom’s result. In this research, we use a literature review method to some related papers corresponding to a derivation of a Lie algebra, Frobenius Lie algebras, and Plancherel measure. Determining a conjecture of a real Frobenius Lie algebra is obtained. As the main result, we prove that conjecture. Namely, for the given the Heisenberg Lie algebra, there exists a commutative subalgebra of dimension one such that its semi direct sum is a real Frobenius Lie algebra of dimension . Futhermore, in the notion of the Lie group of the Heisenberg Lie algebra which is called the Heisenberg Lie group, we compute the generalized character of its group  and we determine the Plancherel measure of the unitary dual of the Heisenberg Lie group. As our contributions, we complete some examples of Frobenius Lie algebras obtained from a nilpotent Lie algebra and we also give alternative computations to find the Plancherel measure of the Heisenberg Lie group.

Abstract

This community service program aims to address the problems faced by Kenayyu Small and Medium Enterprises (SMEs) in Sragen Regency, particularly in the areas of financial management, accounting practices, design innovation, production capacity, and marketing. The urgency of this activity arises from the limited availability of production equipment, unstructured financial recording systems, and lack of marketing strategies, which hinder the competitiveness and sustainability of hand-printed batik businesses. To overcome these issues, the program was implemented through five main stages: (a) socialization, (b) training, (c) technology application, (d) mentoring and evaluation, and (e) program sustainability. The socialization stage built awareness and commitment among partners, while the training improved skills in financial recording, accounting applications, and batik motif design. The application of technology was carried out through the use of dynamo-powered equipment to enhance production efficiency. Mentoring and evaluation ensured continuous improvement and problem-solving, and the sustainability stage encouraged partners to maintain progress after the program ended. These activities have produced significant outcomes, including increased financial literacy, better product design innovation, improved production efficiency, and expanded digital marketing through marketplaces, leading to higher competitiveness and turnover for partner SMEs.
