Physics is an integral part of natural science. Basically physics is the study of natural phenomena in the form of facts, concepts and laws that have been tested by a series of studies. This study aims to describe the implementation of reasoning learning by teachers in public high school students in the city of Palembang. This type of research is descriptive qualitative research. The research was conducted in seven Palembang City State Senior High Schools on Momentum and Impulse material. Subjects in this study consisted of seven teachers and 231 students from seven public high schools in the city of Palembang. Research subjects were determined through purposive sampling technique. The results showed that the implementation of reasoning learning activities was not optimal. Learning the reasoning done by the teacher is limited to reasoning activities which is the final conclusion of the thinking process without observing, asking questions and trying. The final conclusions made by students are only based on the teacher's explanation of the one-way learning process. This can be seen from the percentage of the implementation of reasoning activities on the scientific approach that gets a percentage of 39.04% and is included in the medium category.

Teaching physics by utilizing technology becomes a necessity for high school physics teachers to master. DIGICOM is an innovation in teaching physics that utilizes multi-technology. Interface-connected camera technology can help explain microscopic phenomena observed through a microscope. A total of 19 physics teachers in Batang Regency, Central Java received training on DIGICOM-based science learning. From the preliminary data it is known that almost all teachers have never carried out learning using multi-technology and only 50% of teachers or schools have digital microscopes and digital cameras in their schools. But after getting DIGICOM training in physics learning, teachers already have sufficient knowledge and they have the confidence to be able to implement the results of this training in learning physics in their classrooms.

Performance characterization of simple and low cost Mach Zehnder interferometer (MZI) using step index plastic optical fiber (SI-POF) to temperature variation is presented. The sensor consists of two tapers at several distance forming interferometer. The first taper was designed to be steep to allow excitation of cladding modes, while the second taper was gradual to supress power loss. Characterizations were done in terms of sensitivity, hysteresis and repeatability by analysing the output spectrums recorded by spectrometer at various environment temperature which are 35oC to 85oC with increment of 10oC. The results showed that the sensor has sensitivity of 0.0431 nm/oC and correlation coefficient of 0.9965. Hysteresis of 6.9×10-3was observed. In terms of repeatability, the sensor shows maximum deviation of ±3oC which was mainly resulted from fluctuation of oven temperature. Despite its high deviation, the sensor has advantages of simple fabrication process, low cost, robust and low power loss which make it as a good candidate for temperature sensor.
