<p>This study aims to produce free fall practicum tools by utilizing phototransistor sensors to record the travel time of objects that fall from the starting point to the end point. Dealing with free falling equipment (GJB), equipment in schools is generally still very simple that is using a stopwatch. This type of research is a research and development using 4-d model (define, design, develop and disseminate), which is limited to the stage of development to practicalization activities. Data were collected through validation and responses toward administered questionnaires. Data analysis were conducted by analyzing validation sheet and quantitative response questionnaire by finding percentage of each item on the validation sheet. Then the data validation results are analyzed by descriptive technique to describe the quality of the developed product. The result of calibration of free fall practicum by using phototransistor sensor at 40 cm, 50 cm, and 70 cm distance obtained the average travel time of each object is 0.28 s, 0.32 s, and 0.37 s. These results indicate that the practicum tool has been calibrated. Validation of practicum tool is 72,39% and validation of questionnaire response of practican is 75%, indicating tool categorized valid. Furthermore, this tool is tested in class X.MIA and XI.MIA MAN 3 Payakumbuh which consisted 23 students in the science laboratory of MAN 3 Payakumbuh with the questionnaire response practicality are 87.75% and 84.41% respectively which are categorized very practical.</p>

This study was conducted because of the need to develop students’ spiritual potential in the learning process conducted by teachers of Islamic Education at SMP N 29 Padang. The purpose of this study is to determine the efforts undertaken by teachers of Islamic Religious Education to develop the spiritual potential of students in improving the learning process.In this research, teacher effort in developing potencial student has not been maximal yet. Aamong the indication is that students have not showed their religious attitude to students either through attitude, behavior, speech or association because the learning model created in the learning process has not given opportunity for students to do so. So that the learning has not given meaning to the students themselves which resulted the ungrowth of the students’ awareness.

<p>Research on identification of honey bee using Computed Radiography has been done. The testing was carried out by providing digital radiograph of the three types of honey bee. The voltage of the x-ray generator was varied at 50 kV, 60 kV and 70 kV, while filament current was set at 100 mA and exposure time was at 5 ms. Honey bee was identified based on the image line profile that indicated the distribution of linear absorption coefficient (µ) for each sample. The analyses on the image line profile showed that at the voltage of 50 kV and 70 kV the three kinds of the honey bee can be distinguished. However, at the voltage of 60 kV the difference among honey bee was unable to be identified.</p>

Debating is also assumed as a valuable learning activity for teaching critical thinking and improving communication skills. Debating is an effective pedagogical way because of the level of responsibility for learning and active involvement required by all student debaters. Many teachers realize that the best strategy for motivating the students to communicate in English is by changing the situation in the class. By creating an interesting and motivating environment, the students are expected to be immersed in the activities given by the teachers. Moreover, an ideal teacher should provide opportunities for students to talk by using group work or pair work, and limiting teacher talk. Therefore, the teacher should keep encouraging the students to get involved during the process of learning in the class most of the time.</em></p></div>
