Based on the results of the analysis of the expert test evaluation of the 100 meter short distance running instrument, it is declared valid and reliable, so that it can be used as research material for students of Penjaskesrek, Riau Islamic University.


INTRODUCTION
Branch of athletics is the oldest sport, which has been done by humans since ancient times until today. Basically, almost all sports that are games contain athletic elements such as running, throwing, refusing, jumping and so on. So, it is not wrong if athletics is said to be the parent of all sports. Athletics has several numbers including walking, running, throwing and jumping. Running numbers consist of short distance running, medium distance running, long distance running and marathon. Short distance running has a running number including running 60 meters, 100 meters, 200 meters and 400 meters.
Short distance running is an ability characterized by the process of rapidly moving the body from one place to another. Thus, to produce a fast run, the things that need to be considered are: the posture of the body is leaning forward, the Nova Risma, Kamarudin, Raffly Henjilito, (2021) Construction Of 100 Meters Short Distance Test In Penjaskesrek Students Islamic University Of Riau 156 | Halaman Olahraga Nusantara copyright@Nova Risma footsteps must be longer, the swing of the hand must be in accordance with the movement of the leg and the movement of the arm where the fingers are clenched or opened tightly and relaxed. This is so that the maximum speed can be achieved up to the line finish.
The success of the implementation of the 100-meter short distance running technique can be seen from three phases, namely at the start (willing, ready, yes), the movement sprint (when running, namely swinging hands, footsteps and togok position), finish. As stated by (Mackala et al., 2015) Sprint 100 Meters can be divided into 3 different phases: The block starts with acceleration, velocity maximum, and maintain speed until the line finish.
So that to determine the ability to run a short distance of 100 meters, a standard test instrument is also needed. The current 100 meter short sprint test instrument is that when the starter raises the sign start , the stopwatch is turned on by the timer and the runner runs as fast as possible to the line finish.
Measurements are made, namely the travel time of the runners from start to finish.
When the limb crosses the line finish the stopwatch is turned off. The value of the teste is that the teste does the movement 2 times, the best result is taken which is the data. Values are measured in seconds.
The aim of this research is to make improvements in the 100 meter short sprint test. The components that are repaired are only in the process of running from the of the start to the line finish. Usually the run test uses only the best time taken by the timer. To find out the quality of the 100-meter short distance running students of the Riau Islamic University Penjaskesrek, of course there must be a test instrument and test norms for these athletes. Based on the above background, it is important for this research to be carried out in order to create a standard 100 meter sprint test instrument that complies with the latest IAAF regulations.
Short distance running is a running number that is in great demand by runners, but not all runners can do a short distance run, because it requires high speed from the start to the line finish. According to Dimyati (2017) saying that running is a movement of moving forward or moving forward that is done quickly, because of the thrust of the hind legs on the ground which is done by scavenging, so that both feet can float in the air while running.
Running is a forward motion to move the body as quickly as possible, both feet are present when floating and not attached to the ground or floor (Sukirno, 2012). According to Schmidt et al., (2016) running leads to shorter contact times and increases peak acceleration and strength. Athletes must be able to produce high strength in a very short time. Running a short distance or sprinting is a run that really requires good reaction speed, coordination and acceleration. Sprinting is an number explosive, therefore a runner must warm up sufficiently before doing a training session (Sahadi, 2011). Likewise, according to Teguh (2016) stating that short distance running is often called a sprint, the distance covered can vary, ranging from 100 meters and 200 meters to 400 meters.
Based on the above opinion, it can be concluded that short distance running is the ability to move the limbs, legs, arms and the static parts of the body and even the entire body with the greatest speed so that it can move the body as quickly as possible and both legs are when floating and not sticking to the ground.  (Harrison, 2010) says biomechanics sprint and exercises sprint of various biomechanical models considered in connection with the initial phase, acceleration and speed maintenance sprint 100 meters to enter the finish line. In line with (Sulastio, 2016) said that in order to achieve the right running results, of course there are also several things that must be supported by: good running speed, leg movements, arm movements, posture and strength as well as methods taught by trainers for endurance training. and speed.
The role of physical ability in supporting the achievement of 100 meters is very important, so that athletes who have good physical abilities will certainly have more opportunities to excel. Lactic acid levels also play a big role. (Harliawan and Darminto, 2020).
According to Eddy (2011) states that starting is an initial preparation for a runner to perform a running motion. At the start, it is marked with a line starting starting for the position before the run starts. Start by its usefulness is divided into three kinds of start in start standing /standing start, start floating/flying start, and start squatting /crouching start which is used for short-distance running(sprints).The techniques for starting short distance running are a) Cue "willing", b) Cue "ready", c) Cue "yak" or the sound of a gun (Sahadi, 2011).
Then also explained by Anggara & Saudi (2017) that a good start has several characteristics: 1. Has full concentration, does not think about anything else when the signal is "ready" 2. Puts oneself on the "ready" signal 3. Both feet make explosive movements on the block at an optimal angle at start.
When running fast, the runner is on the toes with the body leaning forward.
Bend your arms 90 degrees at the elbows and swing in the direction of running.
The hands and facial muscles are relaxed, each leg is fully straightened out and the thighs of the leading leg are lifted horizontally, the hips remain at the same height. Entering the line finish is the most important thing in running and determines whether a runner loses or wins. There are several techniques to enter the line finish that can be used by runners, namely: running continuously without changing the running attitude, chest forward or head lowered, both hands straight back and one shoulder advancing forward.
Running a short distance of 100 meters is part of the anaerobic energy system. The anaerobic metabolic system is a series of chemical reactions that do not require oxygen. The anaerobic energy metabolism system is divided into two systems, namely (1) alactic anaerobes and (2) lactic anaerobes (Sukadiyanto & Dangsina, 2011).
The difference between the two energy systems is the presence or absence of oxygen (O 2 ) during the process of meeting energy needs. The anaerobic system, during its energy fulfillment process, does not require the help of oxygen (O 2 ), but uses the energy stored in the muscles, namely ATP and PC. As stated by (Ross & Leveritt 2012) that sprint training adaptation clearly depends on sprint duration, recovery between repetitions, total volume and frequency during training. Kadir (2010) states that the test is a form of evaluation tool to measure how far the teaching objectives have been achieved. Based on the above opinion, it can be concluded that the notion of a test is a measuring tool that has various meanings, one of which is a test that is a measuring tool to measure a person's ability. Likewise in the case of this study, in making the test instrument, it was meant to measure psychomotor ability, especially measuring the psychomotor ability of the slightly modified 100 meter short sprint skill. A good test must meet several requirements, namely; it must be efficient, it must be standard, have norms, be objective, valid (valid), and reliable (reliable).
According to the opinion Fenanlampir, A., & Faruq (2015) Measurement is the process of collecting data or information objectively. Thus it can be said that the measurement can be carried out if an instrument has been implemented then the scores are given with the raw score. Measurements must be carried out in Evaluation is always carried out by referring to the objectives to be achieved in an activity. According to Widoyo (2012) defines that "evaluation is a process or activity of selecting, collecting, analyzing and presenting information that can be used as a basis for decision making and for the preparation of further programs".

METHOD
This research method using the method of research and development, or research and development. According to Sugiyono (2010) research and development methods are research methods used to produce certain products and test the effectiveness of these products. In this study, the aim of this research is to develop or modify the existing form of the 100 meter short distance running test instrument and then make a few improvements regarding the running process from start to finish. There are many development research models that can be used, but in this study using the Borg and Gall model development (Haryati, 2012). This Borg and Gall version development research model includes ten activities, namely: (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, operational field testing, (9) final product revision, (10) dissemination and implementation. The flow of this research is taken from the development of the Borg and Gall model.

The targets achieved in this study were students of the Riau Islamic University
Penjaskesrek. This research is located in Marpoyan, Pekanbaru City and will be carried out after the research proposal is received. The population in this study amounted to 50 students of Pendidikan Jasmani Kesehatan Rekreasi Riau Islamic University and a sample of 50 people using purposive sampling technique date september 2020. The data analysis techniques in this study were as follows: (a) validity test using content validity and construct validity. The construct validity test was carried out by analyzing the results of the 100 meter sprint test result. The data obtained from the test were tested for validity using the help of the SPSS computer program. (b) reliability test to describe the consistency of measurement results with the help of the SPSS computer program.

RESULTS AND DISCUSSION
The short distance running test is a measuring tool used to determine and measure the ability to run well in a short distance race, especially in the 100 meter number. Based on the results of observations, the running ability of the students of the Physical Education and Research Center, Riau Islamic University is quite good. But when running a distance of 100 meters, the sample only focuses on running speed using the time from the start to the position crossing the line finish.
Therefore, it is deemed necessary to make a test instrument for a short distance run of 100 meters, which focuses more on the running process starting at the start, while running, and at the finish. So that it will be more accurate when doing the 100 meter run test.
The 100 meter run test only uses the best time taken by the timer, the repair of components in the 100 meter short run test is only in the process of running from the of the start start to the line finish the test instruments are made of. The 100 meter short run test produced in small group trials is the first step before conducting research in large group trials, for that the data generated is the validation of one test and measurement expert and two athletic sports experts.
Based on the test and measurement of the ability to run a short distance of 100 meters on a small-scale trial on the physical health education students, totaling 25 people.
The test is carried out based on the criteria of the item, Score 0 (zero) if the sample fails to perform all movement points, Score 1 (one) if the sample makes 1 (one) point movement that is done correctly, Score 2 (two) if the sample does 2 ( two) point movements that were done correctly, score 3 (three) if the sample made Based on the data above, the 100 meter sprint test instrument developed was correlated with the total score having a validity of 0.55 and 0.55 which was greater than the r table (0.396). While the reliability result is 0.63 greater than r table (0.396). This means that the expert judgment and the measurement of the 100 meter sprint test are valid and reliable, so they can be used as research.
The results of the validity of large group trials using the SPSS application with the results obtained were 0.68, including the medium category. the validity results that have been known are then compared with the r table value according to the number of samples used in the study. The measurement results of the 100meter short-distance running test that developed the large group trial had a reliability value of 0.71. Based on the data analysis, the short distance running skill of 100 meters is the lowest with a score of 84 and the skill of running the short distance is 100 meters which is the highest with a score of 127. While the results of the research by Henjilito, R. (2017) showed that there was a positive influence between the explosive power of the leg muscles, reaction speed and motivation on the speed of running a short distance of 100 meters in athletic athletes in PPLP Pekanbaru. leg muscle explosion, reaction speed and motivation.
The research results were analyzed by (Harliawan and Darminto, 2020) using descriprive and inferential technique, Based on the results of the analysis of the data obtained, the following conclusions are obtained, among others, that the speed of movement, leg reaction, and leg explosive power contribute significantly to the running speed of 100 meters.
Based on the research and development steps to produce a product that has been carried out, the final product is obtained in the form of a 100 meter sprint test instrument. After the production of this 100 meter short distance running test instrument, students had no more trouble finding a test instrument that was feasible and in accordance with the latest PASI regulations.

CONCLUSION
Based on the results of the analysis from the evaluation of three experts, namely one test and measurement expert and two athletic sports experts, especially in the short distance running numbers, the validity is 0.68 and the reliability is 0.71, including the high category. This means that the expert judgment and measurement of the 100-meter short-distance run test are valid and reliable, so they can be used as research for students of Penjaskesrek, Riau Islamic University.
