Abstract—The graph operation is one method to construct a new graph by applying the operation to two or more graph. One of graph operation is amalgamation, let {Hi} be a finite collection of nontrivial, simple and undirected graphs and let each Hi has a fixed vertex vj called a terminal. The terminal of graph operation is formed by taking all the Hi’s and identifying their terminal. When Hi are all isomorphic graphs, for any positif integer n, we denote such amalgamation by G = Amal(H, v, n), where n denotes the number of copies of H and v is the terminal. The graph G is said to be an (a, d)-H-antimagic total graph if there exist a bijective function f : V (G) ∪ E(G) → {1, 2, . . . , |V (G)| + |E(G)|} such that for all subgraphs isomorphic to H, the total H-weights W(H) = ∑v∈V (H) f(v) + ∑e∈E(H) f(e) form an arithmetic sequence {a, a + d, a + 2d, ..., a + (n − 1)d}, where a and d are positive integers and n is the number of all subgraphs isomorphic to H. An (a, d)-H-antimagic total labeling f is called super if the smallest labels appear in the vertices. In this paper, we study a super (a, d)-H antimagic total labeling of connected of graph G = Amal(H, Ps+2, n) by uses a partition technique with cancelation number. The result is graph G = Amal(H, Ps+2, n) admits a super(a, d)-H antimagic total labeling for almost feasible difference d.

Abstrak: Satu tahun lebih dunia pendidikan menghadapi tantangan yang cukup besar ditengah mewabahnya virus Covid-19. Pembelajaran yang seharusnya dilaksanakan secara tatap muka tidak bisa lagi dilaksanakan karena bisa memicu proses penyebaran virus Covid-19 yang semakin luas. Hal ini menyebabkan pembelajaran online menjadi satu-satunya alternatif model pembelajaran di masa pandemi Covid-19. Sebagai sesuatu yang baru, tentunya pendidik serta peserta didik harus bisa beradaptasi dengan keadaan tersebut. Kemampuan penguasan teknologi pendidik dalam masa adaptasi kebiasan baru sangat diperlukan. Sehingga, tim pengabdian masyarakat melaksanakan kegiatan pendampingan pendampingan pendidik dalam pegembangan media pembelajaran berupa E-Comic tematik berbasis augmented reality terintegrasi dengan ICT di KKG Gugus 01 Desa Panti Kecamatan Panti Kabupaten Jember. Hasil dari pengabdian ini adalah pendidik mampu mengembangkan media pembelajaran berupa E-comic yang terintegrasi dengan ICT. E-comic yang terintegrasi dengan ICT dapat memudahkan mahasiswa dalam memahami materi yang disampaikan oleh pendidik. Hal ini merupakan salah satu upaya dalam mempertahankan kualitas penyampaian materi pelajaran di masa pandemi Covid-19. Hasil kuesioner dari pelaksanaan kegiatan pendampingan pendidik dalam pegembangan E-Comic tematik berbasis augmented reality terintegrasi dengan ICT adalah 35,5% cukup mahir, 38,7% mahir, dan 25,8% sangat mahir dalam membuat media pembelajaran interaktif berupa E-comic dengan aplikasi online maupun offline.Abstract: For more than a year, the considerable challenges as the effect of the Covid-19 outbreak virus has been faced by the education system. Learning process which normally should be carried out face-to-face can no longer be carried out because it can trigger the process of spreading the Covid-19 virus getting wider. For avoiding the spreading of Covid 19, online learning can be applied as the alternative of learning model during the Covid-19 pandemic. As something new, of course, educators and students must be able to adapt to these conditions. The ability of mastering the technology for educators in the adaptation period as a new habits is very important. Thus, the community service team carried out mentoring activities for mentoring educators in the development of learning media in the form of augmented reality-based thematic E-Comic integrated with ICT in KKG Gugus 01 Panti Village, Panti District, Jember Regency. Hopefully, the result of this program can guide the teachers developed a learning media in the form of E-comic integrated with ICT. E-comic integrated with ICT can make students easier to understand the material presented by educators. This is one of the efforts to maintain the quality education during the Covid-19 pandemic. The results of the questionnaire from the implementation of mentoring activities for educators in the development of thematic E-Comic based on augmented reality integrated with ICT are 35.5% quite proficient, 38.7% proficient, and 25.8% very proficient in making interactive learning media in the form of E-comic with online and offline applications.

Pandemi Covid-19 telah mengubah pola pembelajaran secara masif. Proses pembelajaran yang mestinya dilaksanakan secara tatap muka sekarang berubah menjadi sistem pembelajaran jarak jauh atau daring. Penggunaan teknologi dalam pembelajaraan menjadi bagian penting yang harus dikembangkan oleh guru untuk menghadapi generasi Z. Kecanggihan teknologi yang ada saat ini seharusnya menjadi senjata dan media bagi pendidik dalam menyiapkan generasi masa depan sehingga bisa melahirkan anak-anak yang dapat beradaptasi dengan perkembangan zaman, sekaligus tetap menjaga nilai-nilai moral yang luhur di masyarakat. Permasalahn pokok saat ini yang nyata terjadi di lapangan, khususnya di sekolah yang terletak di desa Pakis, Panti, Kabupaten Jember, masih banyak guru-guru yang minim pengetahuan mengenai pemanfaatan teknologi dalam pembelajaran, khususnya dalam hal melaksanakan evaluasi pembelajaran secara online. Evaluasi merupakan komponen yang sangat penting dalam penyelenggaraan pendidikan. Dengan sistem evaluasi yang baik maka kualitas pembelajaran diharapkan akan meningkat. Pembelajaran secara daring yang ada di Kecamatan Panti hanya dikemas secara konvensional, dimana guru hanya memberi tugas via aplikasi whatssapp. Evaluasi pembelajaran yang dilaksanakan kurang optimal. Oleh karena itu, diperlukan suatu pendampingan, sosialisasi dan inovasi baru dalam pelakasanaan evaluasi pembelajaran agar tujuan pembelajaran bisa dievaluasi dengan baik, serta meningkatkan performa sekolah dalam memberikan layanan yang terbaik kepada siswa.

Let a simple and connected graph $G=(V,E)$ with the vertex set $V(G)$ and the edge set E(G). If there is a mapping $f$: $V(G)$ $\rightarrow$ ${0,2,…,2k_v}$ and $f$: $E(G)$ $\rightarrow$ ${1,2,…,k_e}$ as a function of vertex and edge irregularities labeling with $k=max$ ${2k_v,k_e}$ for $k_v$ and $k_e$ natural numbers and the associated weight of vertex $u,v \in V(G)$ under $f$ is $w(u)=f(u)+\sum_{u,v\in E(G)}f(uv)$. Then the function $f$ is called a local vertex irregular reflexive labeling if every adjacent vertices has distinct vertex weight. When each vertex of graph $G$ is colored with a vertex weight $w(u,v)$, then graph $G$ is said to have a local vertex irregular reflexive coloring. Minimum number of vertex weight is needed to color the vertices in graf $G$ such that any adjacent vertices are not have the same color is called a local vertex irregular reflexive chromatic number, denoted by $\chi_{(lrvs)}(G)$. The minimum $k$ required such that $\chi_{(lrvs)}(G)=\chi(G)$ where $\chi(G)$ is chromatic number of proper coloring on G is called local reflexive vertex color strength, denoted by $lrvcs(G)$. In this paper, we will examine the local reflexive vertex color strength of local vertex irregular reflexive coloring on the family of ladder graph.

There are variant of the metric dimensions in graph theory, one of them is a local adjacency metric dimension. Let $W\subset V(G)$ with $W=\{w_1,w_2,\dots,w_k\}$, the representation of the vertex $V\in V(G)$, $r_A(v|W)=(d_A(v,w_1),d_A(v,w_2),\dots,d_A(v,w_k))$ with $ d_ {A} (v, w) $= $ 0 $ if $ v = w $, $ d_ {A} (v, w) $= $ 1 $ if $ v$ adjacent to $w $, and $ d_ {A} (v, w) $ =$ 2 $ if $ v $ does not adjacent to $ w $. If every two adjacent vertices $ v_1 $, $ v_2 \in V (G) $, $ r_ {A} (v_1 | W) \neq r_ {A} (v_2 | W) $, then $W$ is the minimum cardinality of the local adjacency metric dimension. The minimum cardinality of $W$ is called the local adjacency metric dimension number, denoted by $ \dim_{(A, l)} (G) $. In this paper, we have found the local adjacency metric dimension of corona product of special graphs, namely the $ L_n \odot {P_3} $ graph, $ S_n \odot {P_3} $ graph, $ C_n \odot {P_3} $ graph, $ P_n \odot {S_4} $ graph, and the graph $ L_n \odot {S_4} $.

The local antimagic total vertex labeling of graph G is a labeling that every vertices and edges label by natural number from 1 to such that every two adjacent vertices has different weights, where is The sum of a vertex label and the labels of all edges that incident to the vertex. If the labeling start the smallest label from the vertex then the edge so that kind of coloring is called the local super antimagic total vertex labeling. That local super antimagic total vertex labeling induces vertex coloring of graph G where for vertex v, the weight w(v) is the color of v. The minimum number of colors that obtained by coloring that induces by local super antimagic total vertex labeling of G called the chromatic number of local super antimagic total vertex coloring of G, denoted by χlsat(G). In this paper, we consider the chromatic number of local super antimagic total vertex coloring of Generalized Petersen Graph P(n,k) for k=1, 2.

All graph in this paper are connected graph and simple graph. Let G = (V,E)be a connected graph. Rainbow vertex connection is the assignment of G that has interior vertices with different colors. The minimum number of colors from the rainbow vertex coloring in graph G is called rainbow vertex connection number. If wf(u) ̸= wf(v) for two different vertext u, v ∈ V (G) then f is called antimagic labeling for graph G. Rainbow vertex antimagic coloring is a combination between rainbow coloring and antimagic labeling. Graph G is called rainbow vertex antimagic coloring 2-connection if G has at least 2 rainbow paths from u − v. Rainbow vertex antimagic coloring 2-connection to denoted as rvac2(G). In this paper, we will study rainbow vertex antimagic coloring 2-connection on a family of graphs ladder that includes H-graph Hn for n ≥ 2, slide ladder graph SLn for n ≥ 2, and graph Octa-Chain OCn for n ≥ 2.
