I. Introduction
The civilization of a nation can be seen from the level of human education. An educated nation will bring prosperity to all walks of life. The education sector is an important field in developing a country, a developed country can be assured of having a quality education system, this is because the education sector is closely related to human resource development.
The achievement of educational goals alone is inseparable from how a country can organize an educational measurement instrument so that the educational achievement can be known for its results. Various assessment instruments in education are carried out in a country.
Indonesia is a country whose educational assessment instruments are structured from the lowest education units to higher education. Educational assessment instruments in Indonesia in the form of student learning outcomes assessment conducted by the education unit and carried out by the government through the education department and related ministries.
Physical education as with other subjects also conducts evaluation activities. One of the problems related to physical education teacher competencies is the ability of teachers to carry out learning evaluations. Learning evaluation activities become important all subjects are no exception physical education because with the evaluation the teacher can know the extent of the success of the learning he did. However, the reality on the ground is that we often encounter learning evaluations conducted by physical education teachers that are still not by the principles of good evaluation, there are still teachers who give evaluation scores only because they know students only without based on clear evaluation/assessment instruments.
Difficulties in assessing skills cannot be separated from the competence of the physical education teacher itself. The inability of teachers to develop a valid instrument becomes an unsolved problem. Also, limited infrastructure is an obstacle in implementing an ideal physical education assessment. The high cost or difficulty of obtaining learning support facilities becomes a complex problem in physical education.
Speaking about practice tests, which one of the aims is to find out the students' skills, of course, they will not be separated from the assessment instruments carried out, including physical education subjects. Problems that are often encountered in the field, the weakness of assessment instruments to carry out practical tests becomes an interesting problem to be explored. We still often meet in the field of physical education subject practice tests only as a formality of the process that must be carried out without regard to quality. Assessment in education in Indonesia includes 4 competencies, namely spiritual, social, knowledge and skills competencies. Physical education is a subject that is one of the dominant indicators of success in the realm of skills. Therefore, practice exams become very important to be carried out.
Large ball game skills are one of the realms of learning in physical education lessons, where one of the learning media can use volleyball games. Volleyball is a big ball game where one of the playing techniques is service. Services that are taught to 6th-grade students can be divided into two, namely lower service and upper service.
Problems that arise, physical education teachers are not able to carry out a good assessment of the learning process. Therefore, it is necessary to develop an instrument to assess learning outcomes. Focus of Research: First, this research focuses to find out the instrument model for the assessment of low service skills and top service for 6th-grade students in elementary school. Secondly, this research focuses on determining the arrangement of norms and valid and reliable values that will be obtained after making an assessment. Research Object: First, develop an instrument model for assessing lower and upper service skills for 6th-grade students in elementary school. Secondly, determine the arrangement of norms and valid and reliable values that will be obtained after making an assessment.

II. Research Method
Development in research means developing a research product to solve a problem that occurs. The development in this research seeks to solve problems in the world of education, namely the weak implementation of skills tests in physical education. The implementation of skills exams in various schools is still limited, so it is necessary to improve the process of assessing. This is inseparable from the many things that cause all this to happen, teacher competence and the availability of facilities and infrastructure are the main factors in implementing the process.
The purpose of this study was to create a product development instrument for assessing lower service skills and top service in volleyball games for grade 6 students in primary school. Where this type of research is development research is a research approach that has the main goal to solve problems with product development.
The research and development approach in this study uses an educational research and development model. According to Borg and Gall (1983: 772), "Educational research and development (R&D) is a process used to develop and validate educational production".
According to Borg and Gall research and development has 10 stages that must be carried out: (1) research and information collecting, (2) planning, (3)developing preliminary forms of product, (4) preliminary field testing, (5) main product revision, (6) main field testing, (7) operational product revision, (8) operational field testing, (9) final product revision, (10) dissemination and implementation. (Borg & Gall, 1983) In simple terms, this development research is divided into 3 parts: (1) a preliminary study (pre-survey), this section is a research and collecting data activity that has two main activities, namely literature study (literature review and previous research) and field studies. The results of this activity are the implementation of the practical test implementation used by the teacher in physical education learning. (2) the development of the model, the next part is the development of the model, in this section it is an amalgamation of the planning and development of the preliminary form of product in its activities, namely, setting goals, determining the qualifications of the parties involved in research and development, namely the teacher and student. (3) model validation, the last part of this study is simply the model validation done using experimental design (Creswell, 1994: 130-134).

Figure 1. Design and development steps
The subjects in this study were 6th-grade elementary school students consisting of 2 study groups with each group of 28 students in the Creative Elementary School Sidoarjo, East Java, Indonesia area. Subjects were taken randomly by paying attention to the sex of the students concerned. Before determining the sample, obtaining permission to the school institution as well as permission to the parents of students used as research subjects. This research starts from pre-survey activities, limited trials, wider trials and model validity.
Instruments and data collection in this study began with the development of research instruments which include the development of test instruments and the development of assessment scales. Next is the instrument validation to ensure that the instrument to be used meets the requirements.

III. Discussion
In the process of making appraisal instruments, a needs analysis is needed to find out whether the instruments to be compiled by researchers are needed. The results of a preliminary study of 10 physical education teachers were conducted by giving a questionnaire about the importance of service in volleyball as follows: From the results of the preliminary study, it was found that 10 teachers stated the need for instruments in evaluating volleyball service skills. Furthermore, based on literature review, needs analysis and relevant research, an initial draft of the technical service assessment instrument for lower and upper service is compiled in volleyball games containing: (1) identifying aspects of the process being assessed, (2) arrangement of the grid based on indicators, (3) guidelines for assessment and observation, (4) preparing assignment sheets and instructions for student implementation, observation, and scoring.

The draft that was compiled then tested its validity to five experts with the results as in the following From the results of the assessment conducted by the experts, then the content validity calculation is performed using the formula CVR = (2 Mp / M) -1, with the statement that MP is the number of experts who give good grades or with an assessment of 3-4, M is the number Budapest International Research and Critics in Linguistics and Education (BirLE) Journal Volume 2, No 4, November 2019, Page: 634-641 e-ISSN: 2655-1470(Online), p-ISSN: 2655-2647 www. bircu-journal.com/index.php/birle emails: birle.journal@gmail.com birle.journal.qa@gmail.com of experts. The results of the validation carried out by experts give good marks to the draft assessment instruments developed. After the assessment instruments were approved by the experts, the next step was to conduct a small-scale trial of 3 male students and 3 female students in grade 6 at SD Insan Rabbani. From the results of a small scale trial using the Cronbach Alpha statistical test, the results are as follows: Based on table 2, we can conclude that the bottom service and top service techniques. By using the Interclass correlation coefficient (ICC), the value of the inter-brother reliability coefficient is high. Therefore, based on a small scale reliability test, it can then be used for large scale trials.
Implementation of large-scale trials using test-retest to test the validity of the assessment instruments obtained as in the following table: From this table, it can be concluded that the results of the validity of the instrument valuation instruments under service and top service have high validity results. So that the development of lower service volleyball and upper service volleyball technical skills assessment instruments have high scores. It can be concluded that the result of statistical calculation of the instrument of service assessment of lower service and upper service has a high coefficient value, so that it can be used as a standard assessment service technique of lower and upper service in volleyball game grade 6 in elementary school.
Data from the five raters were analyzed for their complete reliability. The results of inter-brother reliability of the instrument of performance evaluation of lower and upper service are broad as in the following table:  Students take positions in the service line in volleyball games 2 If there is a signal that the student is serving for 60 seconds 3 Each student serves up to the opposing area by targeting the back of the field 4 If you hear the second whistle the lower service activity is stopped In ball score 1 2 3 The final product in this research and development is in the form of an instrument to assess the service skills of lower and upper service in volleyball games in grade 6 elementary school students in which there are instructions for use, student assignments sheets, assessment guidelines, assessment rubrics, and scoring tables.

IV. Conclusion
First, the results of this study are arranged components in the implementation of the assessment of lower and upper service techniques in volleyball games on the assessment of grade 6 skills of elementary schools. Second, the assessment components consist of initial attitude, implementation, and final attitude. Third, an instrument of assessment of service skills for upper and lower service is arranged on the 6th-grade students of valid and reliable elementary school. Fourth, effective and low service skills assessment instruments have been developed. Students, feel happy and more motivated to be more active in learning physical education. This happens because they feel the positive impact of the learning process, in particular, the existence of clear instruments in the assessment of learning.
