Abstract

Graphs were first introduced by Leonard Euler through the Königsberg Bridge problem in 1736. Let $G$ be a connected graph with vertex set $V(G)$ and edge set $E(G)$. The concept of distance in graphs leads to the notions of metric dimension and local metric dimension. Let $W \subset V(G)$ with $W = \{w_1, w_2, \dots, w_n\}$. The representation of a vertex $x \in V(G)$ with respect to $W$ is defined by $r(x \mid W) = (d(x, w_1), d(x, w_2), \dots, d(x, w_n)).$ The set $W$ is called a local resolving set of $G$ if for every pair of adjacent vertices $u, v \in V(G)$, $r(u \mid W) \ne r(v \mid W)$. The minimum cardinality of such a set is called the local metric dimension of $G$ and is denoted by $\dim_{\ell}(G)$. This research aims to determine the metric dimension and local metric dimension of the triangular snake graph $T_n$, as well as graphs obtained from the corona operation between $T_n$ and a path graph of order two. The method used is a literature study with an analysis of graph structure and vertex distances. The results show that both the metric dimension and the local metric dimension of the triangular snake graph are equal to $2$. Moreover, the local metric dimension of $T_n \odot P_2$ is $2n+1$, while that of $P_2 \odot T_n$ is $n+3$ for odd $n$ and $n+2$ for even $n$.

Abstract

This community service program aims to improve the digital readiness of 12th-grade students at SMA Negeri 1 Karangnongko in preparation for the Computer-Based National Selection Test (SNBT). Initial observations indicated that assessment activities were still conducted using paper-based methods, limiting students’ exposure to digital examinations. To address this issue, a Computer-Based Test (CBT) system was implemented through socialisation, guided practice, and technical assistance during a try-out session. The program involved 172 students, all of whom successfully accessed and completed the CBT simulation. In addition, 118 students provided feedback through questionnaires, indicating positive responses toward system usability and examination experience. Most students reported that the CBT system was easy to use, helped reduce anxiety, and improved familiarity with computer-based examinations. These results indicate an improvement in students’ digital readiness, particularly in operational skills and examination navigation. Furthermore, the implemented CBT system can be reused independently by the school, providing sustainable benefits for future digital assessment activities.
