INTRODUCTION
As time goes by, the development of science and technology (Science and Technology) is increasingly unstoppable every day.There were many effects of these developments that trigger changes in life.In the past, people used to buy and sell by directly looking for goods to be bought at the market or the nearest shops.However, in this day and age, internet technology has penetrated into the social system of society so that the way people do buying and selling also changed a lot.So far, many buying and selling activities are carried out through online media, for example on social networks Facebook, Twitter and Instagram.In social networks, especially Facebook, people who have similar interests or hobbies will usually form a community, including the buying and selling community.Within the community, they will create their own language variations to facilitate interaction with one another.

Based on this, the present researchers are interested in examining the variations in the language of registers in the online buying and selling group on social media Facebook.Therefore, this research is entitled "Register Buy and Sell Online in the Facebook Group Buy-Sell Any Area Cilegon Serang Banten".The study examines the morphological process.Ramlan (2009, p.21) "morphology studies the intricacies of words as well as the functions of changes in the form of words.In the process of morphology there is the affixing process, the repetition process, the compounding process, and abreviation or abbreviations."Yet, in this study, the researchers only focus on the process of abbreviation.According to Kridalaksana (2010), abbreviation is shortening, while the results of the process are called short.In addition to the morphological process of abbreviation, another thing that was studied was the function of the register language."Function" refers to whatever purpose the language is used (Aslinda and Syafyahya, 2014, p. 89).
The results of this study can be beneficial for high school teachers as they may be interested adapting the result of this study into their teaching material construction.This study brings the analysis of the form of abbreviation and language functions related to online buying and selling trends so that it can be used in learning language, specifically negotiating texts.This study analyses how online trading registers on the Facebook group "Buy and Sell Any Cilegon Serang Banten Region".The present researchers need appropriate and relevant theory in order to respond the research questions and the objectives of this study.The previous researches which likely discuss similar topic can give clear picture of the distinguished difference of the present study can contribute to the field of register language knowledge.Broadly speaking, this research refers to the concept of using register language.As stated by Halliday and Hasan (1992, p.56) registers can be defined as a "variety of languages based on their usage."In other words, the register is the language used today, depending on what is being done and the nature of its activities.In line with this opinion, according to Wardhaugh (cited in Ardi, 2013) the register refers to the use of a specific set of vocabulary related to a particular work or social group.
Furthermore, according to Pateda (Wijayanti. 2016: 40) register is the use of language related to one's work.Register as a form of language variation due to the specific nature of the needs of the user.Responding the problem in this study, the theory that will be used is the theory of abbreviation proposed by Kridalaksana (2010), abbreviation is the dating of one or several parts of a lexeme or a combination of lexemes so that a new form takes the form of words.Another term for abbreviation is shortening, while the result of the process is called shortening.Furthermore, Kridalaksana (2010, p. 162) classified short form of register into: a) Abbreviation, which is one of the results of a shortening process in the form of letters or a combination of letters, both spelled letter by letter or not.
b) Acronyms and contractions, which are shortening processes that combine letters or syllables, or other parts written and pronounced.In other words, if all the short abbreviations are written or pronounced as fair words, they are an acronym.c) Fragment, which is the shortening process that perpetuates one part of the lexeme.d) Symbols, which are shortening processes that produce one or more letters that describe the basic concepts of quantity, units or elements.
With regard to the above theory, the researchers see the function of language correspond to the research problems of this study.As explained by Halliday (cited in Aslinda and Syafyahya, 2014, p. 91), there are seven language functions, namely interactional, personal, regulatory, instrumental, representational, imaginative, and heuristic functions.In summary, the description of the seven functions is as follows: a) The instrumental function aims to manipulate the environment producing certain conditions so as to cause an event to occur.In short, language is used to do things.The orientation of this function rests on the speech partners only.According to Sudaryanto (cited in Aslinda and Syafyahya, 2014) This last function orientation is focused on the speaker himself.
f) The heuristic function is called the participant which functions to gain knowledge.The function of this language is used when asking questions, finding facts and explaining facts, and looking for reality.
g) Imaginative functions function as creators of imaginative systems, ideas or stories.

RESEARCH METHOD
Methods are indispensable to guide researchers from the beginning to the end of their research, from data collection to data analysis.Given the importance of a method, Sudaryato (2018) explains that the method is a way of working by a researcher to achieve the expected goals.In this research, the method used is descriptive research method.Getting to know more about descriptive research methods, Djajasudarma (2010: 9) elucidates that descriptive research methods are methods that aim at making descriptions; the intention is to make a picture, a systematic, factual, and accurate picture of the data, the characteristics and the relationship of the phenomena under study.In addition, the approach taken by researchers is a qualitative approach.Bogdan and Taylor (2015) define qualitative methods as research procedures that produce descriptive data in the form of written or oral words from people and observed behavior.
In a study, especially language research, research techniques are one element that cannot be abandoned.Therefore it is necessary to use techniques in accordance with the objectives to be achieved.
The data collection techniques that the researchers use are literature study techniques; consider techniques, and documentation techniques.In addition, the data analysis method used in this study is the equivalent method and the method of distribution.According to Sudaryanto (2018), the matching method, the determining device is outside, detached, and does not become part of the language (langue) concerned.The padan method is related to the assumption that the language under study already has a relationship with things that are outside the language in question (Sudaryanto, 2018; Aryanti & Zulaeha, 2017).This padan used by the present researchers to analyze the function of the register language found in the Facebook group "Buy and Sell Anything in the Region of Cilegon Serang Banten".
Different from the equivalent method; the method was the deciding tool is precisely part of the language in question itself (Sudaryanto, 2018).This method is used to analyze the form of register language abbreviation found on Facebook groups.The data analysis technique used is the BUL technique or the technique for direct elements.In the BUL technique the method used in the initial work of analysis is to divide the lingual unit of data into several parts or elements (Sudaryanto, 2018).The initial workings of the analysis in this study, dividing each element of the data obtained into lingual units in the form of words.
