This research aims to determine the effectiveness of the self-directed learning model and the discovery learning model assisted by focusky media on the historical analysis abilities and learning outcomes of students in history subjects. This type of research is a quasi-experiment with a sample size of 65 students at SMA Negeri 1 Bangorejo. The results of the t-test of historical analysis ability and learning outcomes, it shows that there is a significant difference with the difference in the average posttest score (...) for historical analysis ability 2.733 and the difference in the average posttest score for learning outcomes 3.059. Then, the historical analysis effectiveness test, it shows a medium category of 0.050, while the learning outcomes show a medium category of 0.053. This shows that experiment class 1 is better than experiment class 2 and the self-directed learning model has proven to be effective in improving historical analysis skills and learning outcomes.

Premature birth or low birth weight (LBW) is predictor of infant morbidity and mortality. Generally, infant with premature birth will be treated on incubator device. Incubator must provide stable levels of temperature, relative humidity and oxygen concentration. Temperature on infant incubator must be maintaned around 36°C-38°C. In order to control that, adaptive Fuzzy- PI controller is proposed and implemented on infant incubator’s prototype. This research use DHT11 sensor as sensing element and the control method are actuated by lightbulbs. The controller (...) used Microcontroller Atmega16 as processor which output determines the amount of power supplied to the lightbulb by employing pulse width modulation and MOSFET triggered circuit. Tests were carried out on temperature references that correspond to the standard incubator temperature range of 36°C to 38°C. References changes (fluctuatif reference) test and disturbances test were also carried out to prove system performance. The tests result on fixed reference temperatures were able to reach a stable setpoint with time rise (tr) around the 200 second with the highest overshoot maximum steady state error below 5%. References change tests and disturbances test successfully proved the controller was able to follow changes in references and overcome the disturbances. (shrink)

Abstract— Unmanned Ground Vehicle (UGV) is a mechanical device that moves on the sky and serves as a means of carrying, transporting something, or mapping the location and controlled remotely. UGV is widely used in a variety of terrain difficult to reach or dangerous for human safety, eg for the location of a natural disaster, radiation, or to defuse the bomb in the military. This research was designed and manufactured human machine interface for remote control system and displayed the UGV (...) movement according to target poin that have been determined. UGV movement data obtained from GPS sensor and encoder. Received data would be showed on computer used visual studio. Measurement data was sent wirelessly from the microcontroller to the computer using the YS-1020UA module. The results showed that the movement of UGV can be displayed on the interface on the laptop. Received Datawas displayed in the form of graphs and data in tables form. UGV can be remotely controlled to move from one target to another, moreover it can also be controlled manually or automatically which can be set throgh the interface. -/- . (shrink)

Abstract—Generator set (genset) is a backup power supply which is used when the PLN supply is off. With such an important function, the generator set maintenance must be taken care of for long life durability. Monitoring activity is usually conducted on a regular basis, but still run manually by relying on operators who go directly to the plant. This research goes over the making of HMI remote control system for generator set in order to produce effective and continuous reporting. HMI (...) is designed by Microsoft Visual Studio 2012 software with C # programming language. The data communication used is serial asynchronous wireless communication using 3DR Telemetry 433MHz. The prototype generator set uses an Atmega16 microcontroller which is programmed by CodeVision AVR 2.05.3. Daily data storage and reports use Microsoft Excel. Based on the tests performed, it can be concluded that the HMI system works well. The HMI monitoring system can accurately monitor the plant on fuel percentage and data difference of 1 celcius degree at temperature. The alarm test works well. The farthest test resulted was 84.6 meters. In testing data storage and daily reports all the required information can be stored properly. (shrink)

Abstract: The development of technology pushes human to increase productivity by changing manual system to automatic system. Modernization affect almost all aspect especially in art. Batik is a ancestor legacy of indonesian people that recogized by UNESCO as culture legacy of Indonesia yet batik industries are not develop as much. Modernization in batik art is expected to optimize its productivity. This research design algorithm and the program in MATLAB that used for controlling movement protype of batik maker 2 dof cartesian (...) robot. The input data is a picture that will be processed to obtain the order of coordinate edge. Then it procesed and sent to plantby using MATLAB based on Graphical User Interface (GUI). The 2 dof Cartesian robot and a pen (end effector) is used to draw a pattern. A servo motor is installed to activate end effector and two stepper motor coupled with thread mechanic that used to move it towards the X and Y axis. Testing is done by sending coordinat orders to the plant or by observing drawing process order. Obtained error from program and algorithm testing is 2,32% . (shrink)
