data. The steps in collecting the data are start from downloading all the posters of Climate Change series from January till December 2014 in the official website of Greenpeace www.greenpeace.org . Then, every datum or poster is arranged into the list and given number in the folder. They are 42 campaign posters in climate change series that published from January till December 2014. Moreover, there are twelve folders created and each folder contains three and more posters. Then, it is taken one poster for every month by using simple random sampling, so there are 12 campaign posters. After the data are collected, the data are analyzed. The texts and picture elements on the posters will be analyzed using the Triadic concept of Charles Sanders Peirce theory to explain the semiosis process and find out the clear meaning of the signs. The last, the researcher makes conclusion from the data which had analyzed. 8 CHAPTER II THEORETICAL FRAMEWORK

A. Previous Research

The research about semiotics has been done before, such as: Cindyramitha, 2012, in her thesis by the title “Semiotics Analysis of Product Packaging Design of Gulaku Sugar Sticks”, used theory of Ferdinand De Saussure to analyze the signs. She explained all the data descriptively. She aimed to gain knowledge about the process of meaning productions behind each visual elements on product packaging design using semiotics analysis with Saussure‟s dyadic model 7 . Anwar Yasin, 2011, in his thesis under title “A Semiotic Analysis of Education Advertisements on Campus Magaz ine”, tried to find out the sign meaning of the education advertisements by using triangle semiotics concept. However, in his analysis chapter, he did not draw the triangle semiotics of Peirce to show the relation between the object, representamen, and interpretant where the combination of the three signs will deliver a clear meaning of a selected object advertisement.
