Abstract

One of the student-centered learning methods which is able to improve the students? learning outcomes is Problem-Based Learning (PBL). This study examined (1) the difference in the learning results of students using PBL and Direct Teaching (DT) with high and low learning motivation and creativity, (2) the influence of learning methods with motivation and creativity toward learning outcomes, and (3) the difference in the learning results of students using PBL and DT in terms of learning motivation and creativity. The subject consisted of students of Vocational High Schools or Sekolah Menengah Kejuruan N 1 Ngawen. The data analysis used an ANOVA test and a T-test. The results revealed (1) insignificantly different  learning outcomes between the use of PBL and DT, (2) insignificantly different learning outcomes with the significance of 0.652 between students with high and low motivation, (3) significantly different learning outcomes with the significance of 0.039 between students with high and low creativity, (4) influence of the interaction between learning methods with learning motivation to the  learning outcomes, (5) influence of the interaction between learning methods with creativity to the learning outcomes, (6) insignificantly different  learning outcomes between students using PBL and DT in terms of learning motivation, and (7) insignificantly different learning outcomes between students using PBL and DT in terms of creativity.

Abstract

This study analysed the implementation of the Indonesian Qualification Framework based vocational curriculum in the three years program of an electronics engineering, Faculty of Engineering, Universitas Negeri Jakarta. The analysis was focused on lecturers and students? views. This evaluation used the model of Context, Input, Process, Product by involving 49 students in the 3rd  semester, 6 lecturers, and administration staff. The findings showed that the implemented learning activities using the new curriculum paradigm are reliable. The context analysis indicated the correlation between lecturers? competence and qualification and the goals of the study program. The input analysis showed that the lecturer's assignment was appropriate and correspond with lecturers? subject and education background. The process analysis revealed that the learning process was in accordance with the lectures? planning. In addition, the practicum activities were reportedly consistent with the academic calendar. The product analysis, in the form of courses distribution each semester, suggested that the needs for improvement to fit the new curriculum paradigm design.

Abstract

This study presents comparison methods in the conversion of a spindle plant in order to obtain an accurate discrete system when compared to a continuous system of spindle.  The accurate conversion results of the continuous system into discrete form are required for implementing the control system of spindle. Comparison methods that will be conducted to convert  the  continuous system of spindle plant into discrete system through zero-order hold (ZOH), first-order hold (FOH), impulse invariant dicretisation, tustin (bilinear), and pole-zero matching methods. The performances of each method in the conversion process have been presented. Conversion performances of continous spindle plant into discrete form using FOH method, showed more accurate compared to other methods. Performances of the conversion accuracy of FOH method have been evaluated in terms of transient responses analysis that closed similar results with a continuous system of spindle plant. At the closed similar transient responses for the discrete system using FOH method show the final value, time to peak, percertages overshoot and setlling time are 0.863 v, 0.910 s, 0 % and 0.550 s respectively.

Abstract

A Raspberry Pi Trainer is a tool which is able to support and facilitate the learning process of the subject of microprocessors and microcontrollers.  The objective of this study was to find out the process and the results of the implementation of a Raspberry Pi Trainer for the subject of microprocessors and microcontrollers in the expertise program of industrial electronics in vocational high schools. This study used a qualitative method. The descriptive data were resulted from the observed students? behavior in the form of the research informants? activities covering the domains of cognitive, psychomotor, and affective. There were 20 informants divided into two classes, 10 in class XII A and 10 in class XII B. Each class consisted of 2 males and 8 females. The results showed the Raspberry Pi Trainer was well applied in practical learning activities. The average abilities of class XII B and class XII A for the domains of cognitive, psychomotor and affective were categorized as very good, good and moderate respectively.

Abstract

Control system on the recycle process of markers ink aims to control charging ink on the recycle process of whiteboard markers ink. The process of opening the lid will automatically proceed with the charging process of whiteboard ink. The objectives of this tool are to control the time of ink charging using the solenoid. Solenoid control using the minimum system of microcontroller. The hardware consists of a circuit of microcontroller of ATmega16, driver of solenoid valve using L298 IC, push button, power supply and mechanics for opening and closing markers. It is expected this system can help the process of ink recharging automatically on the whiteboard markers. The performances of lever cap on the recycle process of markers ink show proper performance. The system can fill ink to the markers accordance with the planning. The volume of the markers ink with capacities of up to 25% with the ink discharge of 0,003 liters / second. The system has an average of percentage error of less than 2% of the measured voltage.

Abstract

A very challenging problem in mobile robot systems is mostly in obstacle avoidance strategies. This study aims to describe how the obstacle avoidance system on mobile robots works. This system is designed automatically using fuzzy logic control (FLC) developed using Matlab to help the mobile robots to avoid a head-on collision. The FLC designs were simulated on the mobile robot system. The simulation was conducted by comparing FLC performance to the proportional integral derivative (PID) controller. The simulation results indicate that FLC works better with lower settling time performance. To validate the results, FLC was used in a mobile robot system. It shows that FLC can control the velocity by braking or accelerating according to the sensor input installed in front of the mobile robot. The FLC control system functions as ultrasonic sensor input or a distance sensor. The input voltage was simulated with the potentiometer, whereas the output was shown by the velocity of DC motor. This study employed the simulation work in Simulink and Matlab, while the experimental work used laboratory scale of mobile robots. The results show that the velocity control of DC motors with FLC produces accurate data, so the robot could avoid the existing obstacles. The findings indicate that the simulation and the experimental work of FLC for mobile robot in obstacle avoidance are very close.
