Abstract

Pandemi Covid-19 yang terjadi pada tahun 2020 memukul perekonomian banyak orang, khususnya UKM di wilayah Kecamatan Gatak, Kabupaten Sukoharjo. Masalah yang dihadapi para pelaku UKM adalah menurunnya penghasilan mereka di masa pandemi ini. Tujuan pengabdian dengan topik optimalisasi pemasaran usaha mikro kecil di masa pandemic covid 19 adalah untuk meningkatkan pendapatan para pelaku UKM dengan menerapkan protocol Kesehatan. Metode pengabdian dilakukan dengan melakukan pelatihan memasarkan produk lewat social media dan pendampingan secara berkala. Dalam pemasaran online, media online memiliki beberapa peran penting termasuk branding, promosi yang efektif. Pendampingan diharapkan dapat memberikan kontribusi positif dalam pemasaran produk UKM. Hasil pendampingan tersebut adalah pertama, para pelaku UKM dalam menjual produknya menerapkan protocol Kesehatan sehingga para konsumen merasa nyaman dan aman, hasil pengabdian kedua adalah para pelaku UKM  bisa memasarkan produknya lewat social media, sehingga produknya lebih di ketahui masyarakat luas.

Abstract

A distance vertex irregular total k-labeling of a simple undirected graph G = G(V, E), is a function f : V(G)∪E(G)→{1, 2, …, k} such that for every pair vertices u, v ∈ V(G) and u ≠ v, the weights of u and v are distinct. The weight of vertex v ∈ V(G) is defined to be the sum of the label of vertices in neighborhood of v and the label of all incident edges to v. The total distance vertex irregularity strength of G (denoted by tdis(G)) is the minimum of k for which G has a distance vertex irregular total k-labeling. In this paper, we present several results of the total distance vertex irregularity strength of some corona product graphs.

Abstract

Let H= (T,S), be a finite simple graph, T(H)= T and S(H)= S, respectively, are the sets of vertices and edges on H. Let σ:T∪S→1,2,· · · ,k, be a total k-labeling on H and wσ(x), be a weight of x∈T while using σ labeling, which is evaluated based on the total number of all vertices labels in the neighborhood x and its incident edges. If every x∈T has a different weight, then σ is a distance vertex irregular total k-labeling (DVITL). Total distance vertex irregularity strength of H (tdis(H) is defined as the least k for which H has a DVITL. Our research investigates the DVITL of the path (Pr) and cycle (Cr) graphs. We establish a lower bound and then calculate the precise value of tdis(Pr) and tdis(Cr).

Abstract

Problem-solving can be understood as a cognitive process in which students know facts, processes, concepts, and procedures and then apply the knowledge to solve problems in real situations. Indonesia’s national average achievement of numeracy skills in 2021, the cognitive process of competence reasoning is higher than the competencies of knowing and applying. This study aims to analyze students' cognitive processes in solving numeration problems related to the algebraic domain. The algebraic domain in this study is limited to competencies in making generalizations from patterns in number sequences and object configuration sequences. This research was conducted qualitatively with a phenomenological design using three high-category and three low-category students to achieve data saturation. The supporting instruments are students' answers and interview results related to the algebraic domain. This study concluded that students' cognitive processes in solving numeracy problems associated with the algebraic domain in the high and low categories have different descriptions. This difference in intelligence has an impact when solving math problems. This research can help enrich the understanding of students' cognitive processes and contribute to the development of better mathematics learning strategies and curricula.

Abstract

Assume G is a graph that is simple, undirected, and connected. If every edge label is a positive integer in the range 1 to ke, and every vertex label is a non-negative even number from 0 to 2kv, then a graph G is considered to have an edge irregular reflexive k-labeling, where k is defined as the maximum of ke and 2kv. The edge weight wt(ab) in the graph G, for the labeling λ, is defined as the function wt applied to the edge ab. The symbol res(G) denotes the reflexive edge strength, which is the largest label of the smallest k. The results of this research are as follows: res(SLm) for m≥2 is ⌈(3m−3)/3⌉ for 3m−3 ≢ 2, 3 (mod 6), and ⌈(3m−3)/3⌉+1 for 3m−3 ≡ 2, 3 (mod 6). res(Cpn ⊙ Nm) for n≥2, m≥1 is ⌈(2nm+2n−1)/3⌉ for 2nm+2n−1 ≢ 2, 3 (mod 6), and ⌈(2nm+2n−1)/3⌉+1 for 2nm+2n−1 ≡ 2, 3 (mod 6).

Abstract

Mathematical literacy or numeracy has gained more attention in the education world in Indonesia. This can be seen through various efforts by the Ministry of Education to continually improve it. The research aims to provide an overview of the implementation of mathematics learning in junior high schools in Surakarta, resulting in the numeracy outcomes of students. This study adopts a qualitative approach with a case study strategy. The research data includes the implementation of numeracy, teacher activities, student activities, school environment, and documents. Data sources come from informants, including teachers and students. Data collection techniques involve interviews and documentation. The research findings reveal that the implementation of mathematics learning that strengthens numeracy at SMP Negeri 11 Surakarta and SMP Muhammadiyah Special Program Surakarta is in the stages of habituation and development. Mathematics teachers play roles as motivators, guides, and facilitators. Activities undertaken include providing books, familiarizing students with solving numeracy problems, assigning tasks, motivating students, organizing activities related to numeracy improvement, imparting knowledge, and allowing students to conduct studies.

Abstract

Let G be an undirected, connected, and simple graph with edges set E(G)and vertex set V(G). An edge irregular reflexive k-labeling f is one in which the label for each edge is an integer number {1,2,…, k_e} and the label for each vertex is an even integer number {0,2,4,…,2k_v}, k = max{ k_e,2k_v}. This type of labeling results in distinct weights for each edge. The weight of an edge xy in a graph G with labeling f, indicated by wt (xy), is the total of the labels on the vertex that are incident to the edge as well as the edge label. The minimum value k of the largest label in the graph G is referred to as res (G), which stands for the reflexive edge strength of the graph G. The topic of edge irregular reflexive k-labeling for mongolian tent graph (M_(m,n)) and double quadrilateral snake graph (D(Q_n )) will be discussed in this paper. The res (M_(m,n)),m≥2,n=3 has been obtained that is ⌈(5m-1)/3⌉ for 5m-1≢2,3 (mod 6) and ⌈(5m-1)/3⌉+1 for 5m-1≡2,3 (mod 6). Also the res (D(Q_n )),n≥2 has been obtained that is ⌈(7n-7)/3⌉ for 7n-7≢2,3 (mod 6) and ⌈(5m-1)/3⌉+1 for 7n-7≡2,3 (mod 6).

Abstract

Let G in this paper be a connected and simple graph with set V(G) which is called a vertex and E(G) which is called an edge. The edge irregular reflexive k-labeling f on G consist of integers {1,2,3,...,k_e} as edge labels and even integers {0,2,4,...,2k_v} as the label of vertices, k=max{k_e,2k_v}, all edge weights are different. The weight of an edge xy in G represented by wt(xy) is defined as wt(xy)= f (x)+ f (xy)+ f (y). The smallest k of graph G has an edge irregular reflexive k-labeling is called the reflexive edge strength, symbolized by res (G). In article, we discuss about edge irregular reflexive k-labeling of alternate triangular snake A(T_n ) and the double alternate quadrilateral snake DA(Q_n ). In this paper, the res of alternate triangular snake A(T_n ) , n≥3 has been obtained. That is ⌈(2n-1)/3⌉ for n even,2n-1≢2,3 (mod 6),⌈(2n-1)/3⌉+1 for n even,2n-1=2,3 (mod 6),⌈(2n-2)/3⌉ for n odd,2n-2≢2,3 (mod 6), and ⌈(2n-2)/3⌉+1 for n odd,2n-2=2,3 (mod 6). Then, the reflexive edge strength of double alternate quadrilateral snake DA (Q_n) ⌈ (4n-1 )/3⌉for n even, 4n - 1 ≠2,3 (mod 6), ⌈ (4n-1 )/3⌉+1 for n even, 4n - 1 = 2,3 (mod 6), ⌈ (4n-4)/3⌉ for n odd, 4n - 4 ≠2,3 (mod 6), and ⌈ (4n-4 )/3⌉+1 for n odd, 4n - 4 = 2,3 (mod 6).
