DEVELOPMENT OF BOOKLET BASED SCIENCE LEARNING MEDIA FOR JUNIOR HIGH SCHOOL

This research is motivated by the low interest in student learning in science subjects, especially class VII Biology material which assumes that Biology material is identical to a lot of writing in books and contains a lot of memorization, educators have not used school facilities to develop learning media and minimal teaching materials are only in the form of worksheets. Students are not interested in learning science. The school is a pesantrenbased school, where students only get information from the LKS and the material delivered by the teacher. One of the interesting learning media is the booklet- based science learning media. This study aims to determine the validity of booklet media and student responses to booklet media. The type of research used is Research and Development which refers to the 4D development model (Define, Design, Development, and Dissemination) from S. Thiangarajan (1974) which has been modified into 3D. The results showed that the results of the material expert validation obtained a percentage of 92%; media experts obtained a percentage of 97.77%; by science teachers obtained a percentage of 100%. Small-scale trials obtained a percentage of 91.06% and large-scale trials obtained a percentage of 92.72%. This it can be concluded that the booklet- based science learning media on the material of the interaction of living things with their environment is valid to be used as a media for learning science biology in class VII MTs / SM

MONO-ENERGETIC BEAMS FROM LASER PLASMA INTERACTIONS*

Abstract A laser driven wakefield accelerator has been tuned to produce high energy electron bunches with low emittance and energy spread by extending the interaction length using a plasma channel. Wakefield accelerators support gradients thousands of times those achievable in RF accelerators, but short acceleration distance, limited by diffraction, has resulted in low energy beams with 100% electron energy spread. In the present experiments on the L'OASIS laser, the relativistically intense drive pulse was guided over 10 diffraction ranges by a plasma channel. At a drive pulse power of 9 TW, electrons were trapped from the plasma and beams of percent energy spread containing >200 pC charge above 80 MeV and with normalized emittance estimated at < 2 -mm-mrad were produced. Data and simulations (VORPAL code) show the high quality bunch was formed when beam loading turned off injection after initial trapping, and when the particles were extracted as they dephased from the wake. Up to 4 TW was guided without trapping, potentially providing a platform for controlled injection. The plasma channel technique forms the basis of a new class of accelerators, with high gradients and high beam quality
