The Decision Support System For The Acceptance of Pencak Silat Athletes in Pra-PON and PUSLATDA Team Selection Using Technique For Other Preference By Similarity To Ideal Solution Method

Pencak Silat is one of the traditional martial arts that originated from Indonesia. The parent of Pencak Silat organization in Indonesia is INDONESIAN PENCAK SILAT ASSOCIATION (IPSI). Pencak Silat is one of the most reliable sports branches at the International-scale Olympics. Proven at the ASEAN GAMES 2018 Olympics and then the Pencak Silat Sports Branch is one of the sports branch of the most gold medal with a total of 14 medals. With the increasingly tight competition of Pencak Silat Sports, the trainer desperately needs athletes who fit certain criteria in order to be reliable in a tournament. In this study aims to assist the trainer in selecting athletes that correspond to the criteria. Therefore, a decision support system is required to assist the trainer in selecting qualified athletes. In this research, using the Technique for Other Preference by Similarity To Ideal Solution method is used to advise athletes who are eligible to be contested according to the calculation result. Result system of decision support system with Topsis method of this research has been tested by Pencak Silat Trainer and produce the results of the selection that is expected by the trainer.


Background
Pencak Silat is one of the traditional martial arts originating from Indonesia. The parent organization of Pencak Silat in Indonesia is IKATAN PENCAK SILAT INDONESIA (IPSI). Pencak Silat is one of the most reliable sports in the International Olympics. Proven at the 2018 ASEAN GAMES Olympics, The Pencak Silat Sport is one of the most gold medal contributor sports with a total of 14 medals. With the increasingly tight competition of Pencak Silat Sports, coaches desperately need athletes who fit certain criteria in order to be relied upon in a tournament. The most important thing for athletes to have is to have hard power, strong physique, high mentality and many more factors that must have fighters who will compete.
Currently coaches still use Microsoft Excel to determine which athletes are eligible to be contested. The effectiveness and effectiveness of the system used is not maximal, Data redudnation often occurs, the calculation of each variable to accept athletes is unfounded. All of these problems resulted in decisions being taken uncertainly on target.
In this study, the authors wanted to create a Decision Support System to make it easier for coaches to select athletes who fit the criteria set by the trainer. Decision Support System is a computer-based system intended to help make decisions by utilizing certain data and models to solve problems that are not structured and influenced by many factors from human and non-human.
The method used is Technique For Other Preference by Similarity To Ideal Solution (TOPSIS). The TOPSIS method has the ability to provide solutions in determining the best decisions, since this method provides an alternative by determining the shortest distance of positive ideal solutions and the longest distance of negative ideal solutions.

Problem Limitation

Literature Studies
In this chapter discusses the study of the library and the basis of the theory used to support the writing of the thesis on The Decision Support System for Acceptance of Athletes Pencak Silat in The Selection of Pra-PON and Puslatda Team Using TOPSIS Method (Technique For Other Preference by Similarity To Ideal Solution). Some of the basic theories in question are Decision Support System (SPK), Pencak Silat, Pra-PON, Puslatda, Technique For Other Preference by Similarity To Ideal Solution (TOPSIS).
In the research on Decision Support System in the application of Topis(Technique For Other Preference by Similarity To Ideal Solution) method,in the journal "Decision Support System for Scholarship Recipients at Saniah Aek Songsongan Private Junior High School with Technique For Other Preference by Similarity To Ideal Solution (TOPSIS) Method" There is an equation of calculation because after the calculation in determining the outstanding and poor students by determining the shortest distance on poverty scholarships and determining the best assessment on the determination of outstanding scholarships.
While in the study "System Supporting The Selection of Athletes Who Deserve to Enter THE TEAM Pencak Silat With Simple Additive Weighting (SAW)Method " has the same topic but differs in the selection of methods. The method used in this research is Simple Additive Weighting (SAW). In this study also discussed about the selection of athletes who are eligible to enter the Pencak Silat team, but in this study only achieved an accuracy rate of 85%. (L;, P;and Mahmudy, 2014) Then in the next journal reference entitled "Best Employee Determination Decision Support System Using TOPSIS Method" has an equation in the calculation using TOPSIS Method. In a company employees are very important assets in the progress of a company. (Knowledge and Computers, 2018)

Decision Support System
Decision Support System (SPK) or Decision Support System (DSS) is a system that can provide the ability to solve problems in supporting decisions that are difficult to calculate or select manually or the ability to communicate for problems with semi-structured and unstructured conditions. This system is used to assist a person or User in decision making in semi-structured and unstructured situations where no one knows exactly how to make decisions that should be made. (Turban and Aronso, 2001)

Technique For Other Preference by Similarity To Ideal Solution (TOPSIS)
Topsis method is one of the methods that are often used to complete decision making practically. Topsis has a concept where the chosen alternative is the best alternative that has the shortest distance from the ideal positive solution and the furthest distance from the negative ideal solution. The more factors considered in the decision-making process, the more realtive it is also difficult to make decisions on a problem. (Widayanti and Wijaya, 2016) The stages in using TOPSIS include creating a normalized decision matrix, creating a normalized weighted decision matrix, determining the ideal positive solution matrix and the negative ideal solution matrix, determining the distance between the value of each alternative and the ideal positive solution matrix and the negative ideal solution matrix, and determining the preference value for each alternative. (Widayanti and Wijaya, 2016)

TOPSIS Prosedure
TOPSIS requires a working rating on each alternative A1 on each normalized Cj criteria, namely: dengan i=1,2,,m dan j=1,2,..,n (1) Then the ideal positive solution A+ and A-negative ideal solution can be determined from the normalized weight rating (yij) as follows: yij = wirij where y + j = max yij if j is the value attribute =min yij if j is the cost attribute A + = (y + 1.y + 2, … , y + n) where yj = max yij if j if the cost attribute A -= (y -1.y -2, … , yn) = min yij if j is the value attribute (2) After that, the calculation of Di + as an alternative distance from the ideal solution is defined as follows: Di + = √ ∑ (y ij =1 − y + ) 2 with i = 1,2,3,….,m …………(3) And the distance to the negative-ideal solution is defined as Si -: dengan j = 1,2,3,….,m ………… (4) So that alternatives can be determined to find the best alternative based on their relativeproximity to the ideal solution(Ci)which is defined as follows:

Pencak Silat
Pencak Silat is a martial arts sport native to Indonesia. Understanding pencak is a technique of beauty movement by avoiding. Pencak can be contested with the means of achievement, while silat is an element of martial arts techniques to fend off, attack and lock so that opponents can not be demonstrated in public. . The parent organization of Pencak Silat in Indonesia is IKATAN PENCAK SILAT INDONESIA (IPSI).

Selection of Pencak Silat Athletes
In this Decision Support System, the criteria used are based on the results of discussions from team trainers, warriors and KONI East Java Here is the table of criteria that have been prepared by the trainer that can be seen in table 1. :

PHP (Hypertext Preprocessor)
PHP is an Open Source server-side web programming language. PHP is a script that integrates with HTML and is on the server (server side HTML embedded scripting). PHP is a programming language that can be used to form a dynamic website page. Dynamic is the page that will be displayed when the page is requested by the User. This mechanism causes the information received by the User to be up to date. All PHP scripts are executed on the server where the script is run. (Subagja, 2018)

XAMPP
XAMPP is free software that supports many operating systems, is a compilation of several programs whose function is as a stand-alone server (localhost), which consists of apache HTTP Server programs, MySQL Data Base, and language translators written with PHP and Perl programming languages. The name XAMPP stands for X (any four operating systems), Apache, MySQL, PHP, Perl. (Ratnasari, 2018)

Database
In simple language, a database is a structured set of data stored on a computer systematically so that it can be checked using a computer program to obtain information from the database. Database understanding is a data storage system where the stored data has been inputted in a storage system. (Pamungkas, 2017)

Flowchart
Flowchart is a graphical depiction of the steps and sequence of procedures in the design of a program. Flowchart helps analysts and programmers solve problems into smaller segments and helps in analising other alternatives to operations.
Flowcharts consist of data flowing through the systems and processes that transform that data. Data and processes in flowcharts can be described online or offline. (Nuraini, 2015)

UML (Unified Modeling Langage)
UML is a method of visual modeling as a means of designing and or creating objectoriented software because UML is a visual language for modeling object-oriented languages, so all elements and diagrams based on uml object oriented paradigm also provide writing standards on the system. UML consists of several diagrams namely usecase diagram, class diagram, activity diagram, sequence. (Hendini, 2016)

Black Box Testing
Black Box Testing method is one of the methods that are often applied because only the lower limit and upper limit of the expected data, the estimated amount of test data can be calculated through the number of entry data fields to be tested, the entry rules that must be met and the case of the upper and lower limits that meet. And with this method can receive unexpected data input then cause the stored data is less valid.

Reasearch Method
A research must have a working concept and a research framework in which consists of steps and explanations in order for the research to run well and targeted. In this chapter will explain the Research Methodology, where in this study use Flowchart diagram as a concept and research framework such as figure 3. Following.

Problem Analysis
To be able to understand the problems in the system of supporting the selection decisions of Pencak Silat athletes in the Pra-PON and PUSLATDA Teams. The first step in this stage is to conduct a Literature Study, decipher the problem, identify the problem. Furthermore determine the purpose of research, selection data retrieval and criteria data.

Literature Studies
there are two stages in the Literature Study.the first stage is to do a comparison of each previous research journal and the next stage is collecting data and information on how to make the system. Researchers conducted direct observations at KONI East Java for data collection and reading books as a reference in conducting research and literature that supports the creation of the system.

Determining Goals
At this stage explain the objectives to be achieved in this research. In this study the targets achieved, especially those that can overcome the problems that exist in the selection of athletes Pencak Silat and can facilitate the selection process of athletes who will prove the selection of acceptance in the Pra-PON and PUSTLATDA Teams.

Data Retrieval
In a decision making system, data is needed as input and output parameters in processing data. In the Decision Support System for the selection of Pencak Silat athletes using this TOPSIS Method, researchers conducted external data retrieval, data required include SitUp data, Ankle Flexibility, Sit and Reach Flexibility,3 RM single Leg Squat with dumbbell,Beep Tets (MFT),Abdominal Roll,20 Meter Sprint,Juggling,Triple Jump,Square Jump,Russian Twist,Hamstring,3 RM Clean and Press, Data taken from KONI East Java Coach, data as criteria to meet the needs of Decision Support System and have accuracy in the data. The data used is the data of KONI athletes in East Java, Pencak Silat sports.

Analysis of TOPSIS Method
After the data is collected, data processing will be carried out to adjust the data activities to be processed in the TOPSIS method consisting of several stages, namely defining the problem and determining the criteria of the desired solution, determining the decision matrix, solution matrix, alterative, and reference values with the aim of qualifying the acceptance of Pencak Silat Athletes in the Pra-PON and PUSLATDA Teams.

System Design
At the design stage of the system researchers used design using the Unified Modelling Language (UML) modeling language. In designing this software, UML is defined by Use Case, Activity, Squence, and Class Diagram diagrams.

Software Implementation
At this stage, researchers will do how to create interfaces and design systems for the selection process of Pencak silat athletes in The Pra-PON and PUSLATDA Teams. Researchers use PHP programming language, while for data management using MySQL. Input from the system is data from athlete test results obtained from KONI East Java and Weighting of each criteria. The output of the system is the result of data selection from the highest to lowest rankings in each team.

Testing
Testing stage is the determination stage to find out if the implementation of Decision Support System with TOPSIS method is in accordance with the objectives to be achieved. This test stage uses the Black Box Testing method to identify errors in the system. So it can be known whether the TOPSIS method can be an alternative result of determining the determination of eligible athletes in the Pra-PON or PUSLATDA teams.
