Abstract

Tujuan dari penelitian ini adalah untuk mengetahui analisis framing (bingkai) berita politik portal media online Beritasatu Indonesia mengenai Tagar #Moeldokosavedemokrat. Dalam menjawab permasalahan tersebut, penulis menggunakan pendekatan konstruktivisme, yaitu analisis yang melihat wacana sebagai hasil dari konstruksi realitas sosial. Penelitian ini merupakan studi kepustakaan (library research) yakni sebuah penelitian yang dilakukan dengan teknik pengumpulan data, literatur atau sumber lain yang berkaitan dengan permasalahan yang akan dikaji dalam studi ini. Pembahasan analisis framing mengenai Tagar #Moeldokosavedemokrat dengan menggunakan metode Zhongdang Pan dan Gerald. M. Kosicki. Penulis menemukan, dari sisi perangkat framing (sintaksis, skrip, tematik dan retoris), Beritasatu Indonesia dalam mengkonstruksi realitas sosial, terutama berita tentang Tagar #Moeldokosavedemokrat ada keberpihakan media atas berita yang menjadi tranding topic.

Abstract

Water consumption is very high in industrial pulp and paper. In addition, water also ranked at third for the world wide used. Low COD ratio (0.3) and biodegradability around 0.5 in wasted is considered ideal. One of the alternative way which is Advanced Oxidation Process (AOP) able to degrade harmful organism who less active in the normal degradation process. Active radicals in AOP act produced as oxidizing agents to mineralize complex chemical substances in waste. One of the active radicals, which is sulfate radical (SO42-) has a high oxidation potential of 2.5 to 3.1 V. Several studies showed that radical sulfates can be produced by catalytic oxidation process, such as combination of Peroxymonosulfate with homogeneous metal ion catalyst (Fe2+, Mn2+, Ni2+, Co2+, Cd2+, Cu2+, Ag+1, Cr3+, Zn2+). In this study, AOP method Peroxymonosulfate which was activated with the catalyst α-Mn2O3@α-MnO2-500 were used to treat COD content in organic waste water from pulp and paper industry. The α-Mn2O3@α-MnO2-500 catalyst was produced from 1:3 molar potassium permanganate and maleic acid that calcined at 500 ºC. These catalysis were characterized by XRD, BET and FESEM. From the XRD analysis obtained a combined peak between α-MnO2 and α-Mn2O3 are comparable with JCPDS standard. From the FESEM analysis, the crystal size of the nanorod obtained is around 18-60 nm in width and 47-185 nm in length. In BET analysis, the surface area is 3.765 m2/g. The degradation of COD content, appear in 50ºC, at retention time of 240 minute, with concentrations of 0.4 g/L catalyst dose and 1.6 g/L Peroxymonosulfate (67,52%).Key word: AOP, COD, Peroxymonosulfate, Waste water, Catalyst

Abstract

Let G=(V,E) be a connected graph and c be a proper vertex coloring using t colors. Vertex coloring on the graph G is a function c:V(G)→{1,2,…,t}, such that c(u)≠c(v) if u and v are two vertices that adjacent to each other. If a graph can be colored with t colors, then the smallest number used on the graph G is referred as a chromatic number, denoted by χ(G). While, the number of distinct ways to color the vertices of G with t colors is called as chromatic polynomial, denoted by P_G (t). In this paper, through axiomatic deductive and pattern detection methods, we propose the chromatic polynomials of complete tripartite graph, denoted by K_((l,m,n) ) for l,m ∈{1,2} and l≤m≤n.Keywords: Chromatic Number, Chromatic Polynomial, Complete Tripartite Graph, Vertex Coloring.  AbstrakMisalkan G=(V,E) adalah graf terhubung dan c adalah pewarnaan titik dengan t warna. Pewarnaan titik pada graf G adalah fungsi c:V(G)→{1,2,…,t}, sedemikian sehingga c(u)≠c(v) jika u dan v merupakan dua titik yang bertetangga. Apabila suatu graf dapat diwarnai sejumlah t warna, maka paling sedikit warna yang digunakan pada graf G disebut sebagai bilangan kromatik dan dinotasikan dengan χ(G). Sedangkan, banyaknya cara yang dapat digunakan untuk mewarnai titik pada graf G dengan t warna yang disediakan disebut sebagai polinomial kromatik dan dinotasikan dengan PG(t). Pada artikel ini, dengan metode pendeteksian pola dan deduktif aksiomatik dirumuskan polinomial kromatik dari graf tripartit lengkap, yang dinotasikan dengan Kk,l,m dengan l,m ∈ {1,2} dan l≤m≤n.
