Abstract

Mathematics plays a fundamental role in developing students' logical, analytical, critical, and problem-solving skills. However, many senior high school students perceive mathematics as difficult and uninteresting due to teacher-centered instruction that provides limited opportunities for active engagement and authentic learning experiences. This community service program aimed to enhance students' mathematical understanding through an Experiential Learning-based FunMath Camp conducted collaboratively by the Mathematics Study Program of the University of Mataram and Universiti Teknologi MARA (UiTM), Malaysia. The program was held over two days, 27–28 June 2026, at Gunung Jae Nature Tourism Park, West Lombok, involving 20 selected senior high school students from across Lombok Island. The activities followed four stages of Experiential Learning: concrete experience, reflective observation, abstract conceptualization, and active experimentation. Activities included interactive lectures, Treasure Map Games, a Mini Mathematics Quiz Competition, and collaborative outdoor learning. Program effectiveness was evaluated using pre-test and post-test scores. As the data were not normally distributed based on the Shapiro–Wilk test, the Wilcoxon Signed-Rank Test was employed. The results showed a statistically significant improvement in students' mathematical understanding, with the mean score increasing from 6.85 to 7.80 (p = 0.012). Although the average N-Gain score was 0.19 (low category), students demonstrated greater engagement, collaboration, and confidence in solving mathematical problems. These findings indicate that the Experiential Learning-based FunMath Camp provides an engaging and meaningful learning environment that supports mathematical understanding and active learning.

Abstract

Prime submodule is the abstraction to module theory of prime ideal in ring theory.  A proper submodule N of an R-module M is called prime submodule if for all r in R and m in M such that rm in N implies r in (N:M) or m in N.  Prime submodule also generalized into weakly prime submodule and almost prime submodule.  This study deal with particular cases of both of them in Z-module M_2x2(Z_9), the three submodules are equivalent in case of non-zero submodule.

Abstract

Unit graph is the intersection of graph theory and algebraic structure, which can be seen from the unit graph representing the ring modulo n in graph form. Let R be a ring with nonzero identity. The unit graph of R, denoted by G(R), has its set of vertices equal to the set of all elements of R; distinct vertices x and y are adjacent if and only if x + y is a unit of R. In this study, the unit graph, which is in the ring of integers modulo n, denoted by G(Zn). It turns out when n is 2^k, G(Zn) forms a complete bipartite graph for k∈N, whereas when n is prime, G(Zn) forms a complete (n+1)/2-partites graph. Additionally, the numerical invariants of the graph G(Zn), such as degree, chromatic number, clique number, radius, diameter, domination number, and independence number complement the characteristics of G(Zn) for further research.

Abstract

The non-coprime graph of the integer modulo group is a graph whose vertices represent the elements of the integer modulo group, excluding the identity element. Two distinct vertices are adjacent if and only if their orders are not relatively prime. This study explores two topological indices, the Hyper-Wiener index and the Szeged index, in the non-coprime graph of the integer modulo-n group. The results reveal that these indices are equal when the order is a prime power but differ when the order is the product of two distinct prime numbers. This research provides new insights into the patterns and characteristics of these indices, contributing to a broader understanding of the application of graph theory to abstract group structures.
