Let G = (V,E) be a connected graph with |V|=n and |E|=m. A bijection f: V(G) U E(G) → {1,2,3, …,n + m} is called local antimagic vertex total coloring if for any two adjacent vertices u and v, wt(u)≠ wt(v), where wt(u) = ∑e∈E(u)
f(e) + f(u), and E (u) is a set of edges incident to u. Thus any local antimagic vertex total labeling induces a proper vertex coloring of G where the vertex v is assigned the color wt (v). The local antimagic vertex total chromatic number χ1να
t(G) is the minimum number of colors taken over all colorings induced by local antimagic vertex total. In this paper we investigate local antimagic vertex total coloring on fan graph (Fn) and graph resulting from comb product operation of Fn
and F3
which denoted by Fnt> F3. We get two theorems related to the local antimagic vertex total chromatic number. First, χ1να
t(Fn) = 3 where n> 3. Second, 3 < χ1ναt(Fn > F3) < 5 where n > 3.
Abstract. Ukm is very influental on the economy of sosials, the economy of the people in bulengan branta before covid19 was clssified as normal, but since the existence of covid19, the communitys economny has decreased, the refore training is made to make hell chips with flavor varians for the communitys as a solution to increase peoples in come, with more pricec and packing. Affordable compared to the direct sale (cassave/singkong mentah) not production proccess with less results the economy of the residents of bulengan branta before the existence of covid19 was high quite, namely 50% after the covid19 decreased to 15%, this happened because of reduced in come and not maximal the use of cassava, with this there will be training in community economy development by making hell chips. Whit this training, it is proven to increase the in come of the residents by 30%.Keywords: economic community, new normal, kripik neraka (chip hell)Abstrak. Ukm sangatlah berpengaruh pada perekonomian masyarakat. Ekonomi masyarakat dibulangan branta sebelum covid 19 tergolong normal, namun semenjak keberadaan covid 19, ekonomi masyarakat semakin menurun, oleh karena itu dibuatlah pelatihan pembuatan kripik neraka dengan varian rasa kepada masyarakat sebagai salah satu solusi menambah pendapatan warga, dengan harga dan kemasan yang lebih terjangkau dibandingkan dengan dijual langsung (singkong mentah) tanpa proses produksi yang hasilnya lebih minim. , ekonomi warga bulangan branta sebelum adanya covid-19 terbilang cukup tinggi yaitu sebesar 50 %, setelah adanya covid menurun menjadi 15 %,hal tersebut terjadi karena berkurangnya pendapatan warga serta tidak bisa memaksimalkan pemanfaatan singkong, dengan adanya hal tersebut maka diadakan pelatihan pengembangan ekonomi masyarakat dengan pembuatan keripik neraka. Dengan adanya pelatihan tersebut terbukti menambah penghasilan warga sebanyak 35%Kata kunci: ekonomi masyarakat, new normal, keripik neraka
This study aims to investigate the properties of cartesian multiplication operations on fuzzy graphs. The properties investigated are cartesian multiplication on complete fuzzy graph, effective fuzzy graph and complement fuzzy graph. The method used in this study is a theoretical research method. The results showed that the Cartesian multiplication of two complete fuzzy graphs is not a complete fuzzy graph. The Cartesian multiplication of the two effective fuzzy graphs is the effective fuzzy graph, while for the Cartesian multiplication of the two fuzzy complement graphs, it is not the same as the Cartesian multiplication of the two effective fuzzy graphs.
