Material law of conservation of energy and momentum is abstract material. Practical tools are needed in learning to prove the law so that it can foster real learning for students. This research method is an experimental method that aims to find out how to test the energy conservation and momentum law practicum kit. The practicum kit consists of wheeled objects as loads, precision rails as slippery trajectories, and infrared sensor devices to detect the speed of motion of objects. The kits that have been compiled are then validated by experts before use. Kit validation results are valid. In the implementation of the kit testing the independent variables selected are object mass and slope height. The test results obtained that the kit equipped with infrared sensors is quite accurate in explaining the law of conservation of energy which is evidenced by the relative error that occurs is quite small, namely 1%. In testing the law of conservation of momentum obtained the result that the momentum value of the two objects before the collision approaches the momentum value after the collision. The kit testing results become a solution and innovation as a practical tool to help with more tangible learning.

The purpose of this study was to determine the quality of learning of the CPS learning model on the ability to solve math problems in fifth-grade students and describe the patterns of students' mathematical problem-solving abilities in terms of learning styles. This research is a qualitative descriptive study with the subject of fifth-grade students at Public Elementary School 1 Kalibawang, Wonosobo consisting of 18 students. The instruments used in this study were test and interview instruments. Data analysis includes reduction, presentation of data, and conclusion. The results showed the quality of learning with the CPS learning model on the ability to solve mathematical problems in both categories. It is shown with the results of the validation of proper learning tools, good quality learning, and the average score of students completing. Students with convergent learning styles can solve problems until the stage of re-checking, but at the stage of planning problem-solving lacks detail. Students with divergent learning styles can solve problems up to the stage of checking back, and can solve them well. Students with an assimilation learning style can solve problem until the re-checking stage, but at the planning stage of problem-solving are not perfect. Students with accommodation learning style can solve problem until re-checking stage, but at the stage of carrying out problem solving are not complete.

Multilayer porous composite have been produced through the heating process at temperature T=700oC for 2.5 h. Single layered porous composite was made with a varied mass percentage of from PEG polymer Â 1% to 10%. Double-layered porous composite were made by the arrangement of porosity (4:3)%, (4:2)% and (3:2)%, while the three-layers porous composite have an arrangement (4:3:2)%. Performance of multilayer porous composite for water filtration with pollutants of methylene blue 100 ppm was estimated from the absorbance spectrum. Rejection of methylene blue pollutants from single layered porous composite increases when the fraction of PEG polymer tend to be smaller in the matrix. Meanwhile, the double layered porous composite has a degradation of methylene blue pollutants are better than one layer. Triple layered porous composite have good performance for the water filtration where all the pollutants of methylene blue be able to be filtered.Â Â Komposit pori berlapis telah dihasilkan dengan proses pemanasan pada temperatur T=700oC selama 2.5 jam. Komposit pori satu lapis dibuat dengan variasi persen massa polimer PEG 1% hingga 10%. Komposit pori dua lapis dibuat dengan susunan porositas (4:3)%, (4:2)% dan (3:2)%, sedangkan komposit pori tiga lapis memiliki susunan porositas (4:3:2)%. Kinerja komposit pori berlapis untuk filter air dengan polutan methylene blue 100 ppm diestimasi dari spektrum absorbansi. Rejeksi polutan methylene blue dari komposit pori satu lapis meningkat saat fraksi polimer PEG cenderung lebih kecil dalam matrik komposit. Sedangkan, komposit pori dua lapis memiliki kemampuan untuk degradasi polutan methylene blue yang lebih baik dari satu lapis. Komposit pori tiga lapis memiliki kinerja yang baik untuk filter air dimana seluruh polutan methylene blue mampu disaring.Â

Komposit berpori dengan bahan dasar limbah kaca dan Polyethylen GlycolÂ (PEG) telah dihasilkan dengan metode pencampuran sederhana. Pori pada komposit terbentuk akibat PEG yang menguap ketika dipanaskan pada temperature 700oC selama 2,5 jam. Variasi pori dihasilkan dengan mengatur komposisi PEG yaitu 2%, 3%, 4%, 5%, 6%, 7%, 8%, dan 9%. Komposit berpori memiliki nilai porositas yang bertambah dengan kenaikan komposisi PEG. Komposit berpori memiliki porositas pada rentang 1% hingga 5% dan nilai permeabilitas komposit berpori yaitu (0.3-25)x10-15 m2. Potensi komposit berpori sebagai filter air diujicobakan dengan mengalirkan limbah air sungai. Hasil pengujian diperoleh air dengan sifat fisis air bening dan tidak berbau, sehingga komposit berpori dari limbah kaca dapat menyaring air limbah.

Telah dapat ditumbuhkan film tipis Ga2O3:ZnO di atas substrat silikonmenggunakan dc magnetron sputtering (home made). Parameter deposisi yangdivariasikan dalam pembuatan film tipis Ga2O3:ZnO adalah daya plasma. Prosespenumbuhan dilakukan selama 3 jam. Struktur film dipelajari dengan menggunakandifraksi sinar X (XRD) dan SEM. Hasil difraktogram XRD dibandingkan dengandata JCPDS untuk mengidentifikasi struktur kristal yang tumbuh. Film tipis yangditumbuhkan dengan daya plasma 20,15 W dan 24,10 W teramati puncak difraksibersesuaian dengan orientasi bidang (201) yang menunjukkan lapisan tipisGa2O3:ZnO memiliki struktur monoklinik dan intensitas tertinggi bersesuaian denganorientasi bidang (400) pada fase kubik. Pada citra SEM dengan perbesaran 10.000kali teramati bahwa film yang ditumbuhkan dengan daya plasma 20,15 Wmempunyai morfologi yang lebih rata. Kondisi tersebut dikarenakan atom-atom yangmenempel pada substrat ada yang terlepas terlebih dahulu sebelum datang atom-atomyang tersputter dari target. Hal ini sebagai konsekuensi laju atom yang menujusubstrat relatif rendah karena ditumbuhkan pada daya plasma yang juga relatifrendah.Kata kunci: Ga2O3:ZnO, daya plasma, XRD, SEM, dc magnetron sputtering.
