The aim of this study was to determine the influence of guided inquiry learning model toward the improvement of students"s scientific literacy in integrated science learning on environmental conservation concept based on local wisdom of Baduy"s society. This study used Research and Development method through pretest and posttest test before and after the guided inquiry learning was done. The objects of this study were 31 students who were following the integrated science lecture in 5 th semester which is prospective science teacher. The results showed that there was an improvement in students' scientific literacy after guided inquiry learning (was applied) as shown with a gain value of 0.16 (N-Gain = 0.16) which was included in the medium category. Based on this result, it can be concluded that there is the influence of guided inquiry learning model toward the improvement of students"s scientific literacy in integrated science learning on environmental conservation concept based on local wisdom of Baduy"s society.

With the development of mobile technology is not only used as a telephone and sms only, but also can be used as a device to control a robot, as well as Android smartphones are already embedded computer features. Robot technology so can be controlled remotely and the desired user. Robot technology is also one that is able to assist the work of humans, such as the draining of human work, as well as having a high risk. Robot function which was made to minimize the risk associated with large heavy physical tasks, positioning an object, and to move goods from one place to another. Therefore designed a robot movers using a servo motor output arm movement, microcontroller as the brain, Bluetooth as a communication medium to send a data or input from the Android application that acts as a device for controlling a robot remotely.

This research aims to investigate the influence of Project-Based Learning (PjBL)- Science, Technology, Engineering, and Mathematics (STEM) on Students' Creative Thinking Skills. The research method was quasi-experiment using a nonequivalent control group design. Samples were taken using purposive sampling technique from two of 11^th-grade science classes as an experimental and a control groups. This study used a test instrument of creative thinking skills. Research data were analyzed using SPSS and Microsoft Excel software. Hypothetical test results were assessed using independent sample t-test, obtained sig value (2-tailed) = 0.01 indicating sig value < 0.05. According to statistical analysis, there is a significant difference between the control class and the experiment class. The n-gain value was obtained with a score of 0.59 (a medium category). This result shows that the application of PJBL-STEM can improve students' creative thinking skills in the static fluid topic (Pascal law).

This study determines the improvement of students' creative thinking using problem-based learning models assisted by interactive multimedia on the concept of substance pressure. Research conducted at SMP 2 Mandalawangi, using one-sample classes, class VIII the second semester of 2017/2018 academic year, was held in May 2018. The method used is quantitative research, while the type used is quasi-experimental research, using a one-group pretest-posttest design research design. The instrument used was a test instrument for creative thinking skills in the form of elaboration questions on the concept of pressure. The analyzing data using paired sample t-test or paired sample t-test analysis to see the effect of PBL on creative thinking skills, and n-gain to see an improvement in creative thinking skills. The study gives an increase in students' creative thinking skills. The average value of 41 to 81 with an n-gain of 0.68 or an improved of 68%, which included the medium criteria. Paired sample t-test results indicate that there is an influence of the use of problem-based learning models assisted by interactive multimedia on students' creative thinking skills on the concept of substance pressure.

A weather monitoring station that is simple and able to take the data of weather conditions parameters can be used to determine the local weather conditions at a point place. The process of data transmission between monitoring station weather conditions can be done by utilizing a wireless communication (wireless) network or the Internet. using DHT11 sensor, BMP180 and LDR to measure weather parameters, among which temperature, humidity, light intensity, air pressure and altitude. With Prototype research methods can provide ideas for the maker and potential users on how the system will function in full shape. The concept of Embedded Systems is growing very rapidly with the number of devices that carry the concept. Embedded System is a computer system with a specific purpose, which is entirely incorporated into the device you want to control. One development tool that brings this concept is Arduino Yun. Arduino that has been equipped with an Atheros AR9331 support for troubleshooting Ethernet networks. In Atheros AR9331 processor has been equipped with Linino OS (based on OpenWRT Linux) to assist in data communications in WiFi or Wire. Embedded systems Yun Arduino microcontroller can be connected with a local WiFi network. With its ability Arduino Yun can send output to the internet via social networks like Facebook. Through Temboo can easily send outputs on Facebook, using Facebook Library which had been prepared by a special Temboo for Arduino Yun and APIs (Application Programming Interfaces). The result is a prototype weather station that can be viewed directly on Facebook as a status within one hour.
