INGGRIS: This study discusses the design of intelligent mobile manipulator using fuzzy logic as a driver of mobile robot and ANFIS method as the driving arm. Mobile robot used is wheeled car, with arm type 1 DOF. The working principle of mobile robot is moving to avoid obstacles recorded by ultrasonic sensors, then the data is processed using fuzzy distance resulting in a movement of a mobile robot to avoid obstacles. The working principle is to take the arm objects located on the x and y coordinates recorded by the camera, and then the data is processed using ANFIS resulting servo motion toward the object coordinates. Runge-Kutta method 4 as a settlement order differential equations of motion of the mobile robot is used to describe the motion of the robot trajectory by varying the motor speed right and left motor speed. On fuzzy, this study uses three inputs, where each input has three categories, resulting in a 27 mobile robot motion logics. Testing the validity of the logic of the PWM output value to produce a perfect validity, that is 100%. Arm manipulator can move toward the coordinates of objects that were detected by the camera using the two methods, the ANFIS and inverse kinematics. However, the results showed that ANFIS method is more effective than the inverse kinematics, by comparison of the results of ANFIS and training data that is close to perfect, that is 99%.

Intensity level as sustainable energy: Analysis of the conversion of energy stored on cicadas sound waves

In this study, the researchers measured cicadas' sound waves, considering that cicadas are mostly found in rural areas. The intensity level meter (AMTAST AMF003) was used with time variations (9:00 JST; 12:00 JST; and 15:00 JST). Measurements of air temperature differences (Krisbow Temperature Humidity Data Logger) were also carried out, and weather conditions were also considered in data collection using satellite data from Himawari, Japan. The interpretation results of intensity level's trend measured at 3:00 pm JST were decreased concerning the changes in days. Meanwhile, the measurement at 09:00 am and 12:00 pm JST did not show a decrement concerning the changes in days (31 days in total). These results show that temperature changes (towards autumn) can affect the intensity level of sound waves. In addition, slightly different intensity levels can affect large changes in acoustic power or the produced sound

Management System of Education: Conceptual Similarity (Integration) between Japanese Learning System and Islamic Learning System in Indonesia

The changing times that followed the development of technology made the education system management must be updated to suit the needs and conditions of the environment. In this article, we look for information about the education system in two different countries, namely Japan and Indonesia. The purpose of this research is to find out the integration between the two countries that have different education management systems. The research method used is a descriptive qualitative method. In this research also, the research method is based on the philosophy of postpositivism, using natural conditions or objects. The instrument used to find out information on the education system in each school uses 10 questions and looks for curriculum information data in general in each country. The findings in this study found that, although the management of the education systems of the two countries was slightly different, Indonesian students could compete to continue their tertiary education to developed countries. Besides, the education system in Japan does not make students from Indonesia experience difficulties

Determining the arm's motion angle using inverse kinematics models and adaptive neuro-fuzzy interface system

Robotics technology is known as a great technology demand to be developed continuesly. One of the important things that need to be considered is the control of the motion of the robot. Movement predictions can be modeled in mathematical equations. Prediction based on learning logic is also very supportive of motion control systems, especially arm motion. In this study, the authors combined the two methods as the main study. The working principle of the arm is to take colored objects detected by the camera. In this study, we made arm four DOFs (Degree of Freedom), but only one DOF is controlled by ANFIS because the other three DOFs only move at two fixed angles. Two methods of determining the arm angle of motion used are inverse kinematics and ANFIS methods. The angle of motion and the position of the red object can be observed in real-time on the monitor with the interface in the MATLAB GUI. The angular output that appears in the MATLAB GUI is sent to Arduino in the form of characters, then, Arduino translates it into servo motion to the coordinates of the object detected by the camera. The results showed that the ANFIS method was more effective than the inverse kinematics model

Islamic Education in Supply Chain System by Prioritizing Manners as a Success Factor of Millennial Generation on Socializing

Abstract-The progress of Science, Technology, Engineering and Mathematics (STEM) in the Era of the Industrial Revolution 4.0 requires that learning systems in schools must be developed by considering the supply chain. Since June 2006 the Tebuireng Islamic Boarding School has been developing an education system based on the supply chain strategy. In this development, the Tebuireng Islamic Boarding School begins with a religious-based education or theology that prioritizes manners in supply chain. In this case, we analyzed learning success factors based on Law Auguste Comte as the objective in this study. The study aimed to investigate the relationship between anticipation ability, supply chain, ability to accommodate and integration of education system with the mediation effect of self-organizing skills. In addition, a collaboration of 3 countries was also carried out to seek integration of schools in developed countries such as Japan and Turkey as a reinforcing factor for the success of the education system for the millennial generation in socializing. The results of the study provide very strong information and compatibility in the success of student learning, attitudes, and behavior as a millennial generation in the Industrial Revolution Era 4.0. The most dominant success factor in learning success based on the results of school integration in Japan, Turkey, and the TebuirengPesantren is the respect for others based on the formation of good characters, such as tolerance, respect, polite in speaking, and polite in acting. Besides, learning models such as Innovative learning are the most suitable models in the Industrial Revolution Era 4.0, because at this time almost all learning is based on the Internet of Things (IoT) as a very good learning media.KemajuanScience, Technology, Engineering and Mathematics (STEM) pada Era RevolusiIndustri 4.0
