Design of Digital Based Volley Ball Basic Techniques Test Instrument

The development of digital technology has penetrated all aspects of life, including the education aspect. The rapid development of technology in the era of the industrial revolution 4.0 is very influential on the methodlearning in various schools and colleges. In learning in the era of digital technology, skills and competencies are the main things that need to be considered. Because in the era of the industrial revolution 4.0, the integration of the use of technology and the internet is so sophisticated and massive. Several challenges arise in facing the industrial era in universities in Indonesia. This challenge is not an obstacle but a driving force for digital use. Universities in Indonesia have developed many learning tools that use digital media. In this digital era the development of technology is developing very rapidly. This is because the world entered industry 4.0 where technology became the most basic thing in it. When the world undergoes a changing era, there are many things that also follow it or in other words, changes occur in several sectors of life. However, it is not just the changes that occur but the challenges go along with it. Angela Merkel (2014) argues that Industry 4.0 is a comprehensive transformation of all aspects of production in the industry through the merger of digital technology and the internet with conventional industries. It can be said that the 4.0 industrial revolution is based on digital. The development of technology and information has brought the current generation into the world of digital literacy. The digital age has become one with the current condition of society. This condition has caused Abstract

many people to be easier, faster and have greater opportunities in finding various information. In addition, one of the benefits of information technology is being able to overcome the limitations of space and time. Workers in all fields during the Industrial Revolution 4.0 era are required to have digital skills, such as in the fields of development, economics and in education. In the field of education for example, an educator must understand digital mastery. Various kinds of technology should be applied in teaching in the classroom. (Sagita and Khairunisa, 2020) Likewise, the State University of Medan (Unimed) feels a positive impact in this digital era. This encourages Unimed to implement an innovative learning system in a network called an Online Information System (SIPDA). This e-learning system is adapted to the latest technological developments. Its use aims to speed up the learning process. Unimed continues to encourage lecturers to use the latest learning in accordance with the latest technological developments. This is to answer the needs of the digital community that is all practical and easy to access information. Furthermore, lecturers at Unimed, including Lecturers at the Faculty of Sports Science (FIK) have made many developments in terms of learning methods, teaching materials that refer to digital learning. However, it has not been widely used for evaluating student learning. Edy (2017:28) emphasizes the importance of learning evaluation by stating that evaluation can be done to determine student learning outcomes, the effectiveness of educational programs, and the internal conditions of universities (self-evaluation).
The distribution of courses in the FIK curriculum consists of theoretical and practical courses in sports. One of the practice courses in sports, including the volleyball course. Volleyball is a compulsory subject for three study programs, namely Physical Education, Health and Recreation (PJKR), Sports Coaching Education (PKO), and Sports Science (IKOR) at the Faculty of Sports Science (FIK) Medan State University (Unimed). Practical lectures are given for mastery basic movements and basic technical skills in volleyball games. The basic movements of the volleyball game include locomotor, non-locomotor movements and their combinations both with and without the ball. The basic techniques in the volleyball game include the underhand passing technique and the service fload, the overhand technique, the smash technique, the block technique, the underhand service technique and the service technique.
The competency standards of volleyball courses are: Students are able to master and practice basic skills in volleyball games properly and correctly, namely: 1) Students are able to master and practice basic movements in volleyball games, 2) Students are able to master and practice basic techniques in volleyball games ( covering the technique of passing down receive service fload, technique of passing over, technique of smash, technique of block, technique of underhand service and technique of tennis service). This is in line with Harini, et al (2018: 125) that mastering basic techniques is the basis for improving skills in playing volleyball well.
The achievement of competency standards in this course is carried out through an assessment process. Assessment and evaluation is the most important part in learning, especially in basic volleyball technical material. Furthermore, some basic volleyball techniques are proposed by Ahmadi (2007:20) namely serve, passing, block, and smash. Through assessment and evaluation, accurate information can be obtained about the implementation of the learning process and the learning success of students, lecturers, and the learning process itself. For this reason, lecturers should have the ability to carry out learning evaluations as well as be able to develop evaluation tools in the form of good tests in measuring the achievement of learning objectives in volleyball subjects.
Based on the results of observations in the assessment process of basic volleyball techniques, the assessments carried out by the lecturers in the three study programs still use assessments based on standard test references for volleyball basic techniques b. The implementation of the test assessment is carried out on the results of skill achievement. Furthermore, assessment measuring tools tend to use norm references. The assessment carried out ignores the mastery of the correct technique. This is contrary to the competency standards that have been determined previously.
Assessment should be used as an attempt to improve an appearance. Therefore, good information is needed and must be valid and reliable, because of the success of student learning in achieving predetermined competency standards. Responding to the development of digital technology, it is better if the assessment of basic volleyball techniques is carried out using digital technology.
Furthermore, a survey was conducted on a sample of students who took volleyball courses in the three study programs at FIK. As for the survey results, 80% of students stated that they were not satisfied with the assessment using the norm reference. 90% stated that they did not know what motion processes needed to be improved on the basic technical assessment carried out by the lecturer. And 100% stated that they accepted that the assessment was done digitally because it would provide easy access to the results of the assessment.
To overcome these problems, it is necessary to find solutions with innovative breakthrough instruments that can provide accurate data on the implementation of basic volleyball technical tests. The use of digital media on the basic technical instrument of volleyball as an instrument to facilitate lecturers in processing grades, because it can be corrected in calculations directly while students immediately get feedback from the results of the tests carried out. For this reason, a digital-based volleyball basic technique test instrument was designed. . Digital-based is the use of technology in the field of sports, in this case the researcher uses a smartphone as a tool to assess through test instruments that have been inputted into the smartphone. A smartphone is a multifunctional cell phone that combines several functions of a PDA, such as a personal scheduler, calendar and phone book. A smartphone is equipped with the ability to access the internet, chat, instant messenger, social networking applications, GPS, e-mail, play online games, play music, videos, take pictures, record sound, to write and edit spreadsheet documents such as word files, powerpoint , pdf and excel. Chuzaimah, et al 2010:315) states that smartphones are designed and work through an operating system, where users can freely add applications, add functions or change according to the user's wishes like a computer in the hand. Smartphone is a mobile phone technology that has continued to develop since its inception and will continue to experience various innovations to meet communication needs. Smartphone is an android operating system that provides open source (open source). According to Nasruddin (2012: 1) Android is an operating system on mobile phones that is open and based on the Linux operating system. Android can be used by anyone who wants to use it on their device. This is because people's consumption patterns at this time always want an ease of communication that can support their daily activities both at work and in other matters. Communication needs, access to information and entertainment are met with an Android-based smartphone. This is in accordance with the opinion of Burnette (2009: 12) Android is a new open source software toolkit for future mobile devices, Android itself was created by the Google company in collaboration with the Open Handset Alliance.
The development of a digital-based volleyball basic technical skill instrument is carried out in several stages. This is in accordance with the opinion of Hadjar (1996:1) Several stages must be passed, namely 1) defining variables, 2) describing variables into more detailed indicators, 3) compiling items, 4) conducting trials, 5) analyzing validity. (validity) and reliability (reliability). The stages of instrument development are also stated by According to Arifin (2012) in general the test can be developed through the following stages: 1) determining the purpose of the assessment, 2) compiling a grid, 3) developing a draft instrument, 4) testing and analyzing questions, and 5) revision and assembling questions (new instruments). Another opinion was expressed by Sugiyono (2008:95) that the instrument is a tool used to measure the observed natural and social phenomena. Furthermore, the test that will be developed in this study is a test of the basic technical skills of volleyball games in the form of observation. Furthermore, Riduwan (2011) observation or observation is a technique or method of collecting data by observing ongoing activities. The skill test instrument developed requires internet access to open the instrument through the android system, Turban, Rainer, Potter (2006;69) "The Internet is a global system of computer networks, a network for various networks; cooperative and selfsustaining public facilities accessible to hundreds of millions of people around the world.
Based on the opinions of the experts above, it can be concluded that the steps of instrument development basically include planning, preparation, theoretical testing, instrument revision, empirical testing and assessment of measurement results. The use of this instrument makes it easy for lecturers, because it is applied via mobile phones so it is easy to carry anywhere. In addition, the use of technology through Android in measuring basic volleyball technical skills tests is expected to be able to answer challenges in the era of the industrial revolution 4.0.
