I. Introduction
Efforts to improve learning outcomes continue to be carried out including improving aspects related to learning activities including developing teaching materials carried out to respond to students to be more interested in learning that will be associated with current technological developments.One product of technology that can be used to develop teaching materials for the learning process is interactive multimedia which is a combination of various media in the form of text, graphics, audio, and interactions that are used to convey information messages from sender to receiver equipped with a controller which can be operated by the user.Efforts can be made to make learning effective one of which is the use of multimedia in interactive learning.Learning by using multimedia will be more interesting, more effective, efficient learning time, improve the quality of learning so that the objectives of a learning activity can be achieved.Munadi (2013: 152) states that the advantages possessed by interactive multimedia as learning media include: (1) students are involved auditively, visually, and kinetically; (2) provide an individual climate of affection; (3) Increase learning motivation; (4) Provide feedback; and (5) the use control is entirely with the user.
Tritech Vocational School which will be the target of research is Information Technology Vocational High School.This school has implemented a learning system that utilizes technology as a medium and aids in learning activities, but not all subject teachers apply the same thing.Indonesian language learning in particular still uses teaching books as a guide and the only source of learning.This is one of the causes of learning activities in Indonesian language subjects tend to be monotonous and boring, because learning activities are still teacher-centered, so there is no interaction with students.The teaching materials that have been available so far are considered not to vary, relying solely on textbooks, newspapers or magazines so as to trigger communication that tends to be in the same direction that makes students inactive and not even critical.This was also explained by Indonesian language subject teachers at Tritech Informatika Vocational School Medan when researchers conducted interviews with Indonesian language subject teachers named Ernatati, S.Pd., and Jayanti Maharani, S.Pd, that the teaching materials used were only books text published by the Ministry of Education and Culture.
The development of science and technology that has been utilized is considered to provide the possibility to develop teaching materials.This teaching material will be a tool or learning aid that is more effective in delivering material and efficient in the use of time and energy.Some of the reasons for the use of interactive multimedia-based teaching materials can improve the effectiveness of the learning process, namely: 1) allowing direct interaction between students and subject matter, (2) the learning process can take place individually according to students' learning abilities, (3) able audio visual to increase interest in learning, (4) able to create a continuous learning process.

The Nature of Teaching Materials
Teaching materials are all forms of material used to help teachers or instructors in carrying out teaching and learning activities in the classroom.The material in question can be written or unwritten material.Ministry of National Education (2008: 6) states, "Teaching materials are all forms of material used to help teachers / instructors in carrying out teaching and learning activities.With teaching materials, it allows students to learn a competency or basic competency in a coherent and systematic manner so that accumulatively able to master all competencies as a whole and integrated (Majid, 2012: 173).Prastowo (2013: 297), revealed that teaching materials are a set of materials that are systematically arranged, both written and not so as to create an environment or atmosphere that allows students to learn.There are also those who argue that teaching materials are information, tools and texts needed by the teacher or instructor for planning and reviewing the implementation of learning.
Teaching materials are a set of learning tools or tools that contain learning materials, methods, boundaries, and ways of evaluating systematically and interestingly designed in order to achieve the expected goals, namely achieving competence or sub-competence in all its complexity (Widodo and Jasmadi in Lestari, 2013: 1).Another opinion describing the material or learning material is basically the "content" of the curriculum, which is in the form of subjects or fields of study with topics / subtopics and details (Ruhimat, 2011: 152) Based on some understanding of teaching materials can be concluded that teaching materials are a set subject matter or a set of tools and materials systematically compiled by the teacher and used in learning activities so as to create an environment or atmosphere that allows students to learn and be able to achieve predetermined goals.

Definition of Media
The word media comes from Latin medius which literally means 'middle', 'intermediary' or 'introduction'.In Arabic the media is an intermediary or delivery message from the sender to the recipient of the message.Gerlach & Ely (1971) in Azhar Arsyad (2015) said that media when understood broadly is human, material, or event that builds conditions that make students able to obtain knowledge, skills, or attitudes.Teachers, textbooks, and school environments are media.More specifically, the notion of media in the teaching and learning process tends to be interpreted as graphical, photographic, or electronic tools to capture, process, and reconstruct visual or verbal information.
Learning media is everything that can be used to convey messages or information in the teaching and learning process so that it can stimulate the attention and interest of students in learning.Learning technologies are studies and ethical practices to facilitate learning and improve performance by creating, using, and managing appropriate technological processes and resources.Learning resources are understood as devices, materials, equipment, arrangements, and people where learners can interact with the surrounding environment which aims to facilitate learning and improve performance (Januszeswki and Molenda, in Azhar Arsyad: 2015).

Understanding of Multimedia
Multimedia comes from Latin, which is from the word "multi" which means a lot; various and "medium" which means something that is used to convey or bring something.Some definitions of multimedia according to some experts include: 1.In accordance with the opinion of Vaughan (1994: 4) in Azhar Arsyad (2015: 3) multimedia is "various combinations of text, graphics, sounds, animations, and videos that are conveyed using computers or other electronic devices".2. Multimedia refers to a combination / synchronization of media flow (any synchronized media stream) ".An example of multimedia is moving images that are synchronous with sound (including television broadcasts and modern films) (Green & Brown, 2002: 2) in Azhar Arsyad (2015). 3. Heinich, Molenda, Russell & Smaldino (1999: 229) in Azhar Arsyad (2015) argues, "multimedia refers to various combinations of two or more media formats that are integrated into the form of information or instruction programs".Based on these opinions, it can be concluded that multimedia is a combination of various media in the form of text, graphics, audio, and interaction and is used to convey messages or information from the sender to the recipient of the message or information.

Negotiation Text
Negotiation is a form of social interaction that functions to reach agreement between parties who have different interests.In negotiations, the parties try to resolve the differences with dialogue.Negotiations are carried out because interested parties need to agree on issues that require joint settlement.Another definition of negotiation according to E. Kosasih (2014: 85) is: 1. Negotiation is a process of joint decision-making between several parties that have different interests.2. Negotiation is a way of making decisions that can be agreed upon by two or more parties to satisfy the satisfaction of interested parties.

III. Research Methodology
This type of research is development research (Research and Development) which is a study used to produce certain products and test the effectiveness of these products.This research develops Indonesian language teaching materials in interactive multimedia-based negotiating text material for grade X SMK level.This research and development refers to the theory of teaching material development proposed by Borg and Gall (in Sugiyono, 2015: 35) in the book Research Methods and Development (Research and Development).
Agreeing with Sugiyono, Sukmadinata (2012: 164), reveals that R & D is a strategy or research method that is powerful enough to improve practice and a process or steps to develop a new product or perfect an existing product that can be accounted for.The steps of the research and development process indicate a cycle, which begins with the need, problems that require solving using a particular product.Development research is also widely used to develop teaching materials, learning media and learning management.
This research was conducted at Tritech Informatika Vocational School Medan which was addressed at Jalan Bhayangkara No. 484, Indra Kasih Village, Medan Tembung Subdistrict.The reason for choosing this school is Tritech Informatika Vocational School Medan is one of the technology-based Vocational Schools that has very adequate facilities for conducting research using interactive multimedia as teaching material.Each class is facilitated by one type of LED television monitor unit that can be connected using an HDMI cable for students.Other facilities are a laboratory for multimedia majors and laboratories for computer network engineering majors that can be used as a means of supporting learning.The school program that applies one student one laptop (one student one laptop) is very possible to use interactive multimedia as a learning medium that can support student learning outcomes.As far as the knowledge of researchers is at this school has also not been conducted research on the same problem.This research was conducted from March to April 2018.
The development of interactive multimedia-based teaching materials on negotiating text material has been validated by 2 material experts, namely the lecturer of the Postgraduate of Medan State University and an Indonesian language subject teacher.The purpose of material expert validation is so that the content of the material in the teaching material is in accordance with the students' needs and the clarity of the delivery on the material concept.
The validation stage is carried out by the validator by reviewing the teaching materials that have been designed.Instrument validation sheet for learning material experts consists of indicators of designation, namely the suitability of the material with SK and KI, the accuracy of the material, the updating of the material, and encourage curiosity.The validator scores each indicator, then fills out the improvement notes or general comments to revise the improvement of the teaching material to be tested on the field.
Based on the results assessment of the material expert validation base on the proper aspects of the contents were obtained the result is 98.3% with a very good category for interactive multimedia-based teaching materials on negotiating text material.Based on the results obtained from expert validation, it can be concluded that interactive multimedia-based teaching material on this negotiating text material is "feasible" used in learning Indonesian, especially in negotiating text material.Data from the material validation of the experts on the feasibility aspects are as follows: results of the material expert's assessment it can be concluded that the feasibility aspect of the contents of the topic is very good.Furthermore, the assessment of the material expert validator is related to aspects of language feasibility.The percentage obtained from the results of the material expert's assessment related to the feasibility aspect of the language is 82.9 with a very good category.The following is the presentation of the assessment related to the language feasibility aspects by material experts: can be seen that the average score of each assessment indicator is 93.3 for straightforward language, 100 for communicative language, 90 for dialogical language, 80 for language compatibility with student development, 100 for language compatibility with development, and 100 for the use of terms, symbols or icons.It can be concluded that the aspect of content eligibility based on the results of the assessment by material experts is very good category.
Material experts provide scores in the form of assessment and give advice to researchers.Suggestions given in the form of suggestions submitted directly or delivered in writing, are expected with the advice given can be used as a reference for improvement of interactive multimedia-based negotiating text teaching materials developed.The following is a suggestion from the expert validator that the material will be presented in the following table.
