Finding Kicking Range of Sepak Takraw Game: Fuzzy Logic and Dempster-Shafer Theory Approach

Abstract

Sepak takraw is played by two regus, each consisting of three players. One of the three players shall be at the back and he is called a Tekong. The other two players shall be in front, one on the left and the other on the right. Having volley kicked a throw from the net by a team mate, the ball must then travel over the net to begin play. During the service, as soon as the Tekong kicks the ball, all the players are allowed to move about freely in their respective courts. The novel approach is the integration within a Tsukamoto's Fuzzy reasoning and inferences for evidential reasoning based on Dempster-Shafer theory. Sepak takraw is a highly complex net-barrier kicking sport that involves dazzling displays of quick reflexes, acrobatic twists, turns and swerves of the agile human body movement. Because of the human’s involvement in the game, the Fuzzy Logic type reasoning are the most appropriate. The individual rule outputs of Tsukamoto's Fuzzy reasoning scheme are crisp numbers, and therefore, the functional relationship between the input vector and the system output can be relatively easily identified. The result reveals that if Tekong is kick far and front player is kick near then another regu's player is kick far, if Tekong is kick near and front player is kick far then another regu's player is kick near, moreover possibility of kicking range is another regu's player is kick far in kicking range.<br /><br />

Prediction of Layer Chicken Disease using Fuzzy Analytical Hierarcy Process

“…Fuzzy Logic can handle problems with imprecise data and give more accurate results. Professor L. A. Zadeh introduced the concept of Fuzzy Logic [11]- [14]. Fuzzy analytic hierarchy process (AHP) proves to be a very useful methodology for multiple criteria decision-making in fuzzy environments, which has found substantial applications in recent years [15].…”

“…Many factors that cause chickens are often infected by diseases that can even spread to the same poultry, seasonal change factor one of them. The weather is too hot and the place is too humid too not good for chicken health [10] [11].…”

“…Following the statement, several agencies undertook the research and development of the Decision Support System concept. Decision support systems have been used on research relating to sports [5][6][7][8][9][10], the detection of the disease [11 -21] and education [22]. Basically DSS is designed to support all decision-making stages from identifying problems, selecting relevant data, defining approaches used in the decisionmaking process to evaluating alternative selection.…”

“…As an agricultural country, Indonesia has a great opportunity to accelerate the pace of development and economic growth through agriculture [1][2][3]. The livestock sector, which is part of the agriculture, has an important role [4][5][6]. Construction of a close farm is part of the agricultural developments that support the provision of animal origin food that is nutritious and high competitiveness, and create jobs in the field of agribusiness [7][8][9].…”
