I. Introduction
Vocabulary is one of the essential language components in studying English. It is necessary in the sense that words are the basic building blocks of language, the unit of meaning from which larger structures such as sentences, paragraphs and whole texts are formed (Read, 2000 : 1). If people have less vocabulary, they not only cannot understand others saying, but also cannot make sentences to transfer their messages to the other people.
Thus, they will understand English expressions if they have enough vocabularies. "If you spend most of your time studying grammar, your English will not improve very much. You will see most improvement, if you learn more words and expressions. You can say very little with grammar, but you can say almost anything with words!" (Thornburry; 2002: 13). So, vocabulary is an important thing to learn English without understands grammar deeply meanwhile sometimes the teachers still find out any problems in students vocabulary.
In the fact at SMPN 18 MATARAM there are several problems was faced, there are: The students" enthusiasm and active learning are still not visible, the students still lack on vocabulary, They still lack facilities to improve their English learning.

Game is an alternative way to teach. One of the alternative games is charades game. So, based on it the aim of this study is to investigate the effect of charades game toward student's vocabulary. This study was conduct at the first grade students of SMPN 18 Mataram in academic year 2017/2018. This study used quasi experimental design that is used pre-test and post-test control group design. The population of study involved 40 students from two classes SMPN 18 Mataram in academic year 2017/2018.The writer took all of the students as a sample, they are 20 students belong to the experimental group and 20 students in control group. In this study, the writer used vocabulary test consist of 20 items multiple choice covered with indicator of vocabulary consist of spelling, pronunciation and meaning. The result of this study, the students could understand about spelling, pronunciation and meaning and they could answer the test vocabulary easily through charades game. In this data, pre-test and post-test as the research technique of data collection, then followed by analyzing the data using t-test formula. The level of significant is at 0, 05%, ttest = 2,99 and t-table= 2,02, Alternative Hypothesis (Ha) was accepted and Null Hypothesis (Ho) was rejected. It means that there was significant different between the students pre-test and post-test scores. Thus, the writer concludes that charades game on the student's vocabulary has effect.
. The writer believes that the game can be the way to minimize the student's boredom in learning vocabulary.

A. Research Design
The method that used in this research was Quasi Experimental with the Non equivalent Control Group Design. According to Nunan (1992) Quasi Experimental is giving pre-test and post-test, using control group and there is no determination of subject randomly. In this study, the writer was used quasi experimental because the writer believe quasi experimental helped the writer to investigated that charades game has effect in teaching vocabulary at the first grade students of SMPN 18 MATARAM. There are some procedures that used in this research as like the researcher divide the group into two group namely experimental group and control group first group call experimental group was treated by using Charades game, while second group call control group was not used charades game.

B. Population and sample
Population is object or subject which has quality and characteristic used by the writer to study then made the conclusion (Sugiyono, 2014: 80). The total of population in this study at the first grade students of SMPN 18 MATARAM in academic year 2017/2018 were 40 students which divided into two classes, they were VII A 20 students, VII B 20 students. Setyosari (2015: 220) states that sample is a group of objects, people, events, and so on which is a representation of the whole. Simply Ary, Jacobs, and Sorensen (2010) A sample in a research study is the group on which information is obtained. Arikunto (2002:134) states that if the subject of population less than 100, its better to take all of them.
Based on the statements above, in this research the writer was applied purposive sampling. This population is less than 100 people and in this research the writertook all of the students as a sample they were VII A 20 students as the experimental group and VII B 20 students as the control group

C. Research instruments
In this study, the writer used a test vocabulary as an instrument. In this study, the writer gave vocabulary test for the students before and after giving treatment. The test in the form at multiple choice consist of 20 items that covered with indicator of vocabulary consist of; pronunciation, spelling and meaning. The sources of instrument taken from the When English Rings a Bell book.Score is the result of work gives the figures obtained by adding up the numbers for each items in the correctly test while the value is a number (can also letter) which is the result of change score Sudijono (2007:309). The correct answer weights does not necessarily have a score of 1 but also can have1 " , 2 " , 5 and so on. In this research the writer gave score 5 if correct answer and gave 0 if incorrect.

D. Data Collection
The writers collected the data from pre test and post test of the students score experimental group and control group. There are steps of collecting data as follows:

Pre-test
This is the first step in gathering the data,the writer gave the students pre test in the first meeting in the classroom. That pre test aimed to know underlying knowledge of the students in vocabulary. The kind test is multiple choices the topic is "things and animals" with 20 questions.

The student's correct answer and duration of the time is about 60 minutes. The test is same as the one is given in pre test.

E. Data Analysis
The writers used experimental research that describes a quantitative degree. The data collected from the result of pre-test and post-test. In calculating the students mean score of experimental group and control group, the researcher used the following formula: a. To find the students mean score of experimental and control group, used the following formula:

My = !
Where: Mx: the mean score of experimental group My: the mean score of control group X: the total score for experimental group Y: the total score for control group N: the number of sample a. To find out the standard deviation of experimental group and control group. The formula of standard devotion as follow: 1. Find out the standard deviation of experimental group. The formula as follows:

"
-" Where: X :The students standard deviation for experimental N: Number of sample 2. Find out the standard deviation of control group, the formula as follow:

A. Data Findings
In this chapter, the writer focus on the statistical analysis of data obtained from the pre-test and post-test of experimental and control group. The design was select two classes as experimental and control group. The total population were 40 students consisted of two classes that were class VI1 A 20 students, V1I B 20 students and the writer was took all of the students.

A. Computation of mean score
The student's individual score for both experimental and control groups can be seen on the following tables: To get mean score of two groups in this investigation, the writer applied the following formula: From the table, to get mean score of two groups in these investigations, the researcher applied the following formula:  Based on the data above, it showed that the students post-test higher than pre-test with score (900/20) = 45 and (1395/20) = 69,75 It means that there was significant difference between before and after treatment students were taught by charades game.
In hypothesis the writer used t-test formula. The level of significant is 0,05%, t-test = 2,99 and t-table= 2,02. From analysis, the Alternative Hypothesis (Ha) was accepted and Null Hypothesis (Ho) was rejected. It means that there was significant different between the students pre-test and post-test scores. Thus, the writer concludes that charades game at the first grade students of SMPN 18 Mataram has effect on the student's vocabulary.
