Abstract

This study is aim to establish the efficacy of mobile application based on android for learning vocabulary to the
ten level learners. In this point, the product is a mobile application, students’ book and the teacher’s book. The
researchist applies Research and Development (R & D) pattern adapt from Sugiyono (2016). The pattern in
this study research and development (R and D) The subject of this research was 20 students of a random school
from SMAN 1 Kademangan and SMAN 1 Blitar also five teachers for a random school inBlitar Regency. The
results of the first step prove that problem solving and problem-solving abilities are obtained by analyzing
policy research, conducting monitoring, questioning and answering, and questionnaires. The result of creating
problem abilities and solution which become an obstacle in learning vocabulary is the lack of interest in reading
students so that their vocabulary mastery was not much. They have a lot of difficulty remembering foreign
words, if they have difficulty in mastering or mastering the meaning of foreign words. The result of the design
and development shows that the Mobile Application was valid. In general, of the three module validators, 84%
and the three media validators are 86, 9%. The results of the product experiment prove that this form is
appropriate to be applied to students in vocabulary upgrading and is claimed to be sourced in general. While
the result of product test showed the modelwith total student respond 81,43% and with total teacher respond
absolutely agree 88,25%. The research was carried out on five tenth grade English teachers of MA and SMA,
and students from several tenth grade of Senior High School. The product has an important effect on the

1. INTRODUCTION

Vocabulary is one of the most important parts of teaching English, along with other components such as
structure, pronounciation and intonation. If a student is weak in vocabulary mastery, he cannot communicate
his or her thoughts and ideas clearly both oral and written. Likewise, listening and reading skills will be
constrained by limited abilities. Jeremy Harmer (1991) said that if language is the body, then form is the bone
that makes the framework, whereas vocabulary or speech is the flesh that makes the body form. That way a
person will not be able to speak in the target language if his code ability does not meet. From the above
description can be concluded the inability of most high school students to communicate in English one factor
is due to lack of vocabulary mastery.

Those issues of vocabulary should be solved; as a result, it will be difficulties for the student to continue
consecutive level or grade. Not only that, students have little encouragement in practicing English as a result
they feel English is a burden. Moreover, the student can have dissatisfaction in form. One of the ways in which
to teaching methods that may create students motivated to find out English is sing the acceptable strategy,
like mobile game based on android.

From those issues higher than, the researcher resumes that the teacher desires an answer to resolve the student
issues by developing mobile application supported for learning vocabulary. The name of game is VocApp.
VocApp could is anapplication for the full category that give a support student to analysing their lexicon words.
There are several arguments why I select VocApp because of the media to boost their vocabulary mastery. First,
VocApp may help the students to analysing their lexicon throughout the class. It will enchant the students
concern and their complicity within the teaching and learning method. Second, students will learn the way to
understand one another. Third, VocApp will produce pleasing surroundings. Students will get pleasure from fun
and joyful learning. Fourth, VocApp will facilitate students correct and remember their lexicon one thing that
happened within the application. It should facilitate students keep in mind the language related with it. So,
the students can improve the vocabulary.

2. RESEARCH METODE

The objective of this research is to develop a mobile application for learning vocabulary to the ten level students.
The pattern in this study is research and development (R and D). It discusses the study and development method
which covers approach and research design, research framework and procedures, plan of product design
(analysis, design and product development, hypothetical product and product specification), validations of
design product, trial product (the design of the research, population and sample, data collection technique,
research instrument, data analysis technique) product evaluation, product improvement, and publication.

Based on the research finding that has clarified by the study above and based on three research problems in
chapter I. There could be shown as follows.The development process of VocApp as a learning media through
several stages, as follows: (1) Analyzing potential and Problem, (2) Data Collection, (3) Product Design, (4)
Students and Teacher Response, (5) Product Revision, (6) Product Validation, (7) Product Revision, (8) Final
Product. The development of the VocApp was used to teach tenth-grade vocabularies. The manufacturing
process was carried out in stages and to produce learning media that was suitable for use in the vocabulary
learning, a series of validation processes were carried out with media experts, material experts, and teachers’
and students’ responses.
