INTRODUCTION
Education has a strategic role to prepare the young generation who meet qualifications appropriate to the challenges of the 21st century, which includes skills that focus on the skills of learning innovation (1) critical thinking and problem solving; (2) communication and collaboration; and (3) creativity and invention (Trilling, 2009: 49).In the meantime, based on English Skills Report (2010: 37) States that team

RESEARCH METHODS
This research is a research and development by implementing 4 d models in accordance with Thiagarajan & Semmel (1974:5-9).

Time and place of Research
The research was carried out in December 2016-April 2017.Field trials in April 2017 in SMP N 1 clove cigarettes.

Target/Subject
Subjects in the study were 27 learners classes VII B SMP N 1 clove cigarettes.

Analysis Of Learner Response Against LKPD IPA
The results were analyzed with learner response calculation of average score each aspect of the assessment are then converted in accordance with table 1.

The Analysis Of Collaborative Skills Learners
An analysis of skills of collaboration with the calculation of the average of the data sheet observations, self-assessment, and the judgment antarteman the percentage calculation is then converted according the table 2. Then test with a significance test, Mann-Whitney U with a hypothesis: H0 = there is no difference before and after collaboration skills using LKPD H0 = there is no difference before and after collaboration skills using LKPD As for the decision criteria used is if the value of Asymp.SIG (2-tailed)< 0,05 maka H0 ditolak, Jika nilai Asymp.0,05="" maka="" h0="" ditolak,="" jika="" nilai=""></ 0,05 maka H0 ditolak, Jika nilai Asymp.>SIG (2-tailed) > 0.05 then H0 are received.

Analysis Of Communication Skills
Analysis of communication skills with the calculation of the percentages was converted in accordance table 2 calculation and gain score with the conversion of the qualitative data fit score being table 3. Next U-Mann Whitney test with a hypothesis: H0 = there is no difference in communication skills before and after using LKPD H0 = there is no difference in communication skills before and after using LKPD As for the criteria for the decision are the same skills analysis collaboration.

Collaboration Skills Improvement
The results increased collaboration skills learners in mind based on the results of the initial assessment before using LKPD and final assessment after using LKPD shown in table 4.

Improved Communication Skills
Results improved communication skills are presented in table 5.
skills and communication skills (collaboration) rated be the skills most needed in the world of work.Therefore, the necessary communication and collaboration skills are grown early on.World Education contributes in generating qualified workforce of the 21st century, so that it can link and match with the real needs of the business world and the job market.Demikin however, at the moment a lot of practice learning the IPA lacking build skills needed in the workforce, especially the skills of communication and collaboration.Based on early observations conducted in SMP N 1 clove cigarettes obtained problems: (1) the collaborative skills of learners is still low, indicated by the absence of a clear division of tasks at the moment are working together in groups and lack of sense of value the between group members; (2) communication skills also are still characterized by low skills speaking learners is not good; (3) teachers very rarely use the learning materials in the form of science student worksheet and if using only refers to the text book and there is no development of teachers.These problems indicate that there are still learning in learners a less controlled collaboration and communication skills.One of the reasons, is due to the inaccuracy of the learning model applied and lack of learning materials.Then, as the solution of learning need to apply the model of project based learning (the execution) which has a stage able to guide learners to develop both of these skills by facilitating learners to berinvestigasi, solve problems, are studentcentered, and produce real results of projects (Yuni Wibowo, et al, 2015: 49) as Matthew Widodo Wibowo (2014) which suggests that the execution is one of the models that are able to achieve menjembantani 4Cs Skills such as collaboration and communication skills.According to Santyasa in (Melda Ariyanti, 2017:3) that "in project based learning, collaborative dilkukan project and innovative, unique, focused on solving problems related to the lives of the learners".In addition, he had to do the development of learning materials in the form of the development of Learner Worksheets (LKPD).The determination of that constituted this LKPD the kinds of learning materials, LKPD is the most variable in accordance with the research.Based on the thinking that has been outlined above, then it's very important research done by title: "The development of Learner Worksheets IPA-based Project Based Learning to Increase the skills of collaboration and communication skills Learners Class VII".
in research-based science student worksheet the execution is to increase collaboration and communication skills learners Class VII.Procedure This research consists of four stages, namely the stage define, design, develop, and disseminate.Stage define consists of the initial analysis, analysis of the learners, analysis tasks, concepts, analysis and formulation of learning objectives.Stage design consists of a drafting instrument, selection of media or materials, choice of format, and the initial draft.Develop phase consists of validation by expert lecturers and teachers of the IPA, and then conducted trials of development.Disseminate stage done in limited spread to the teacher in junior high school N 1 clove cigarettes.Data, Instruments, and Data collection Techniques The instruments used in this research in the form of sheets, science student worksheet question form validation response learners against science student worksheet, observation sheets keterlaksanaan learning, collaboration skills selfassessment question form, the now antarteman assessment skills of collaboration, collaborative skills, observation sheets and sheets of observation skills of communication.Data Analysis Techniques Technique of data analysis used in this study are as follows.1. Analysis of The Results of The Validation Science Student Worksheet Data obtained from the results of the validation are analyzed to find out the feasibility of LKPD IPA with based on table 1.
is ideally Byway Maximal ideal score = grain criteria x highest score Maximal ideal score = grain criteria x highest score Then reliability and validation expert lecturers and teachers IPA can be set with the formula The results of the validation LKPD IPA reliability if it has reliability above 75%.
Validation LKPD IPA LKPD IPA developed rated by expert lecturers and teachers of the IPA.Validation is performed against the component that includes LKPD (title, basic competencies, lesson learned, feasibility feasibility include LKPD content, linguistic, presentation, and kegrafisan.Based on the assessment of expert lecturers and teachers of SCIENCE, overall LKPD stated worth with excellent category (A).Reliability analysis based on the results obtained and 93.72% percentage of 99.25% on validation and feasibility component against LKPD IPA. 2. Learner Response Dididk participant response against LKPD IPA review of eligibility and Execution-based LKPD LKPD on sub aspects of the sentence and the linguistic clarity of presentation, questions, kemenarikan appearance LKPD, and consistency of the writing obtained an A category very well.
