Forces is a part of vector mechanics. Students’ ability in completing the physics’ questions related to force and motion in general is still low. This research aims to know the influence of student worksheet as a systematic approach to problem solving toward students’ achievement. This research is a Pra-Experimental Design with One-Group Pretest Posttest that engages one class from grade X at SMAN 1 Batusangkar. The research data includes knowledge competence taken by using pretest and posttest, and students’ outcomes when the teaching was running were taken by using student worksheet. The analyzing data is using N-gain test to see the increasing of students’ outcomes in the teaching learning process, and using the relationship of pretest variable (X) and posttest variable (Y) test to see how big its influence toward students outcomes. From the data analysis can be concluded the two outcomes of the research data. The first one is the comparison between the students’ pretest subjection mean with the student worksheetsubjection mean and the posttest subjection mean which have the increasing and decreasing in the teaching learning process. The comparison of the highest subjection mean from the outcome of N-Gain test is the comparison between the subjection of pretest and the subjection of posttest which is 0,58. The second one is the outcome of the relationship between pretest score (X) and posttest score (Y) is 20,43%. It shows that the use of student worksheet in systematic approach to problem solving gives influence toward students’ outcome as big as 20,43%.

Currently theeprogressoof material nanocomposite can be applied for some of electronic device, bio medic, and electronic engineering. This is because nanocomposite has multifunction of magnetic properties. Most of device use nanoparticles was made from ferrite material, such as MnFe2O4 with high electrical performance, high magnetic permeability. And as matrix used PANi with good thermal stability and high conductivity. With this advantages, synthesis both material can be applied for electronic device like magnetic sensor. Synthesis MnFe2O4/PANi nanocomposite material with 30%, 40%, 50%, 60%, and 70% composition variation of MnFe2O4 with Sol-Gel method has been success. MnFe2O4/PANi nanocomposite was prepared by make of Fe2O3 precursor, make MnFe2O4 and PANi solution with sol-gel method, make MnFe2O4/PANi nanocomposite with spin coating, heating, and sintering the nanocomposite. This nanocomposite characterized with XRD, FTIR, and VSM. Magnetic properties nanocomposite were measured withaa Vibrating Sample Magnetometer (VSM). Result of VSM shows value of coercivity (Hc), remanence magnetization (Mr) and saturation magnetization (Ms). Highest value offcoercivity shows in 60% composition variation with score 389,99Oe, from the value of coercivity, we can classified this nanocomposite as a hard magnet. And for the value of saturation magnetization is 1,07 memu and remanence magnetization is 0,35 memu. The applied field of nanocomposite shows in loop hysteresis with range -10000≤ H ≤10000, it show the ferromagnetic behavior.

In the integrated optical system (Integrated Optics), the raised-strip waveguide is part of the photonic divices used as a medium of light propagation. Physical parameters of raised-strip waveguide mode waveguides affects that can be passed on the waveguides. Given the relative complexity of the calculations - calculations in determining the number of waveguide modes, in this research, and numerical analysis made in an application program in order to facilitate the determination of the waveguide mode. Research conducted including descriptive research using a numerical approach. Used numerical approach is the bisection method is an ideal method to find a result with the use of iterative or repetitive calculations. Furthermore, with this method using Matlab software program designed 2007. Were run on the Windows XP operating system based on research conducted in the form of GUI matlab program that displays the dispersion curves. Generated that variations in physical parameters such as refractive index, thickness and wavelength lebal films and give effect to the number of raised-mode strip waveguides of photonic divices. Where the greater the difference in the refractive index is given, the more the mode waveguides can be missed.

Indonesia is one of the archipelago countries rich in the abundant natural resources potential one of them is iron sand. Iron sand can be found in Mount Marapi located in West Sumatera Indonesia.Gunung is classified as the active volcano in Sumatra located in the district Agam. The existence of iron sand is only in the exploitation in the raw state (raw material) so it has a high selling value that is by knowing its characteristics. The characteristics of iron sand based on Crystal structure, the size of crystals and know the magnetite elements of iron sand that exist in the region Agam regency. This research is a type of experimental research conducted in the Materials Laboratory of Physics Department. In this study variations were performed on milling time. X-Ray Diffraction (XRD) is used to identify the phase, structure and size of crystals. X-Ray Fluorescence (XRF) is used to obtain data of magnetite content in iron basest before and after milling. In this study obtained XRD test data that due to increased time milling phase changes from hematite to magnetite. The increasing variation in milling time causes the change of magnetite structure from cubic structure to cubic structure. Increased milling time, magnetite crystal size increases up to a certain milling time and then decreases. As in the magnetite crystals before dimilling, 1.08 nm, after dimilling with 25 hours, 30 hours, 35 hours and 40 hours variations were obtained at 1.14 nm, 1.20 nm, 1.23 nm and 1.61 nm respectively. Furthermore, there was a decrease in the variation of mill-ing time of 45 hours obtained by 1.29 nm
