INTRODUCTION
Education is a forum that serves to prepare human resources who have competence in carrying out the functions of life.
The education system should not be separated from the changes that occur in various fields as a result of globalization.
The rapid development of science and technology today can have a significant influence on the world of education.
All components of education are expected to be able to adapt so as not to experience gaps in facing the progress of the times.
In an effort to educate the nation's life, improving the quality of education is very important for sustainable development in all aspects of human life.
The national education system continues to be developed in accordance with local, national and global needs and developments (Mulyasa, 2.
For some materials, mathematics is presented in real-life-oriented daily problems.
It aims to make mathematical material easier to understand.
Students are required to be able to solve real-life-oriented math problems.
There are several factors associated with low mathematical problem solving ability.

Development of Media Interactive Problem Based Learning Android-Assisted to Improve Student at SMA Negeri 10 Medan application of conventional learning models, namely lectures, questions and answers, and giving assignments or homework.
Ay Based on observations made in class XI IPA-I SMA Negeri 10 Medan, it shows that conventional learning methods with lectures and question and answer activities .
eachercentered approache.
are dominantly used in learning mathematics.
The problems obtained from the observations are:
The mathematics learning system in class is saturatesd and monotonous.
Students do not carry out interactive activities in following the learning process in class.
The learning system in schools is still limited to conventional learning .
ot using learning There is still a lack of use of media that functions as a student learning companion that can support learning so that it is necessary to have student assistance in the learning process on the material on derivative.
The following results were obtained based on interviews with the Mathematics teacher of class XI IPA-I SMA Negeri 10 Medan.
The obstacle experienced by the teacher lies in the students.
Students tend to be less active in asking and answering during the learning process.
Teachers use lectures, questions and answers, discussions, and assignments in learning.
Most students still find it difficult to understand the subject matter, primarily material that is not easy to learn.
The ability of students to solve real-live .
problems is still in low category because students find it difficult to interpret story questions such as which statements and which questions are in the question.

Hal 383-396 The low score of students' mathematics occurs because during the learning process there are always obstacles for students to understand it.
Such as the lack of mastery of the material by students so that it has an impact on low learning outcomes.
This is also in accordance with the results of an interview with UmmiAulia.
Pd as a mathematics teacher, that in learning mathematics, due to the limited media available in schools, teachers mostly explain the material from the textbooks provided and do not use learning media.
The lecture method is one of the learning models that is often used by teachers, the use of this method causes students to have low learning desires and students feel bored quickly and the lack of practice questions given to students makes students less active in participating in learning.
in class and it tends to be difficult to get the KKM standard score set by the school.
Development through innovation of teaching media for mathematics textbooks is required by using e-learning/mobile android media which can improve the quality of education in an application called Android Studio.
Based on this description, researchers are interested in conducting research and trying to develop learning modules in learning mathematics.
The development of mathematics learning modules is very important in order to motivate and increase student achievement to learn and make students active in the teaching and learning process and will help students to learn mathematics easily.
Therefore, it is necessary to conduct a research entitled development of media interactive learning problem based learning androidassisted to improve student outcomes and motivation at SMA Negeri 10 Medan.

-Evaluation The results of several evaluations from each stagefound that the SMA N 10 MEDAN level required the delivery of varied learning materials, so researchers developed learning media using Android Studio.
Evaluation results were obtained from expert advice and teachers during mediatrials, sothatfromthis evaluationstage revised.
Based on the results of theimplementation that was carried out by 35 students, the percentage of results was91.
8% with the criteria of "Very EffectiveAy.
-Discussion This research was conducted at SMA N 10 MEDAN class XI IPA-I.
This research was conducted to determine the validity, practicality and effectiveness of learning media using Android Studio.
This research uses the ADDIE development model which consists of 5 stages, namely analysis, design, development, implementation and evaluation.
At the analysis stage, interviews were conducted with the school so that through interviews and initial observations it was concluded that the school needed learning media.
The needs analysis aims to find out the problems that exist in schools so that learning media can be developed using Android Studio.
The second step is the selection of materials.
The material chosen for developing Android Studio learning media is the Derivative topic.
The researcher chose the topic Derivatives.
The curriculum currently used is the 2013 Curriculum.
In the Core Competencies there are several basic competencies that students must achieve, including: .
concepts and definitions of derivatives, basic derivative formulas, and operational functions.
This analysis was carried out to find out what subtopics should be included in learning media using Android Studio.
After the analysis stage, the design stage includes searching for reference books for material derived from algebraic functions, example questions, mathematical terms in English as well as reference practice questions and answers contained in learning media using Android Studio and product design.
Next is the development stage.
The development stage is the stage of creating learning media using Android Studio.
Making this learning media starts from the book cover along with the title, introduction, table of contents, materials, sample questions, student activities and closing.
After the learning media using Android Studio is created, an evaluation is then carried out using a modified assessment questionnaire with a Likert scale of 1 to 4.
