One of the interesting physical phenomenon to be studied is about eccentricity of the Moon's orbit on the movement of the Earth and the Moon as explained in Kepler's Law. In order to explain the phenomenon,several research has been done to determine the measurement accuracy of Moon disk diameter using Trackers and to know the result of the eccentricity value in the application of Kepler's Law. This research can produce eccentricity values accordance with the application of Kepler’sLaw. The research method used is Image Analysis Techniqueassisted with Tracker. The result of this research shows that the eccentricity value obtained is 0.07 ± 0.01. This is in accordance with Kepler's first Law which stated that orbits of each planet and satellite is an ellipse and has an eccentricity value of 0

The aim of this research is to develop Atwood machine propswith sensor-based PIR (Passive Infrared) to determine the acceleration value of earth gravity. This type of research is an experiment conducted in the physics laboratory of Universitas Indraprasta PGRI. Atwood machine was developed by using PIR (Passive Infrared) sensors to detect the movement of the objects used. Based on the trialof the result of the data analysis experiment tool, the acceleration of gravity was obtained (9.87 ± 0.08) m/s2. Whereas the value of acceleration of gravity in the literature is 9,80665 m/s2. The obtained results shows that the acceleration of gravity obtained in this research is not much different from the acceleration value of gravity  found in the literature so that Atwood machine tool that is developed by using PIR sensor is recommended to be one alternative tool in determining the acceleration of earth gravity.

The physics problem solving is needed students to overcome the phenomenon of physics. The development of technology in physics learning is able to explain the concept of abstract physics. This study aims to know effect of use interactive learning media based Microsoft Excel on the physics problem solving. The subject on this media is Heat and Temperature. The research method used is pretest-postest controlled group design. The analysis technique is used t-test with SPSS 16.0 with a margin of error of 5%. The results of this study showed that the mean scores of post-test treatment class students significantly better than the average score post-test control class indicated by the average score of students' post-test treatment class at 80.26 and scores the average post-test control class at 68.00 and with SPSS analyze sig value is 0.000. While the average score gain results-physics students learn physics class treatment significantly better than the average score gain results Physics students learn physics-control class indicated by the average score of physics problem solving gain of 0.77 and the treatment class the average score gain control class student physics problem solving of 0.63.

Learning achievement is the result achieved by someone after doing the learning process. One of the factors that influence learning achievement is the use of the learning model. This study aims to know the differences in achievement of students learning to use problem-based blended learningmodels and traditional blendedlearning. This study uses a quasi-experimental method of "non-equivalent pretest-posttest control group design." The study population is all class X IPA with a total of 6 classes or 210 people. The sample consists of 3 classes or 107 people.Student learning achievement data were analyzed by descriptive analysis and ANOVA one-way (α= 0.05). The results of this study reveal that there are differences in student achievement due to the learning model. Higher learning achievement was achieved by problem-based blended learningmodels (F = 264.307; α<0.05). The LSD test results showed that the learning achievement of students in the MBLBM group was higher than MBL, the learning achievement of the MBLBM group was higher than that of MPK, and the learning achievement of the MBLBM group was higher than that of MPK.

The use of a smartphone as a mobile learning tool in schools is controversial. On the one hand, the teacher prohibits it because it would interfere with the learning process in the classroom; and on the other hand, the teacher saw a lot of potentials can be used from mobile technology. The goal of this study is to describe how the development of secondary schools in Indonesia can facilitate students through the use of mobile learning with the hope that it can be taken at the school level policies to strengthen the existing learning system so that students can achieve optimal learning competencies. This research used descriptive qualitative evaluations to make observations on the application of mobile learning in several secondary schools in several regions in Indonesia during 2015. The results of this study indicate that some of the schools that have implemented mobile learning have a tendency that mobile learning was not planned and structured as a school program; so that the advantages of mobile technology has not been effectively used. Two important things to solve this condition are the availability of government policy and improving teachers literacy in managing mobile learning application.
