Title

KAJIAN SIFAT MAGNETIK SEDIMEN TELUK KATURAI PULAU SIBERUT KEPULAUAN MENTAWAI HARIS, VENNY; Rifai, Hamdi

This study aimed to examine the magnetic properties of sediments from Teluk Katurai Siberut island Mentawai islands. The study on sediment samples from Teluk Katurai had been carried out by using three methods, i.e., measurements of AMS (Anisotropy of Magnetic Susceptibility) to determine the anisotropy shape of magnetic susceptibility, IRM (Isothermal Remanent Magnetization) to identify the their magnetic minerals contains based on the saturation curve, and AAS (Anisotropy of Anhysteretic Susceptibility) that produce anhisteritik susceptibility. From the stereonet plot and other anisotropy parameters were obtained that ellipsoid susceptibility form is oblate. It was also obtained that the type of magnetic mineral is magnetite based on magnetic saturation curves. Meanwhile the identification of grain size distribution was obtained by plotting the value of AMS versus AAS. The plots showed the magnetic grains of sediment was approximately 0.2 µm to 0.1µm.Key words: magnetic susceptibility, anisotropy, anhisteritic susceptibility

This study aims to determine the design specifications set tool-making experiments to determine the kinetic coefficients and a coefficient of restitution of the collision of two objects using laser diode and sensor based LDR arduino uno. Results of the study is the design tool set of experiments could measure the kinetic coefficient between the glass material with glass with a relative error of 2.5%, wood with wood with a relative error of 1%, and steel materials with wood with a relative error of 0.5%. The coefficient of restitution is obtained for glass with glass material is 0.062, wood with wood is 0:49, and steel materials with wood is 0:22.Key words: kinestetic cooficient, restitution, sensor, laser dioda, LDR, arduino uno

This study is conducted to identify changes in the magnetic properties of agricultural land due to the use of chemical fertilizers such as urea. Soil profile sampled in this study came from Tarab River District Tanah Datar West Sumatra. Soil sampled from the ground which has not been used as agricultural land and agricultural land that has been using chemical fertilizers. For the initial stage , the identification of changes in the magnetic properties of magnetic susceptibility measurements performed through. Measurements were performed by using two mass -specific frequencies of low and high frequencies of magnetic susceptibility ( ?LF and ?HF ). Measurement of low frequency magnetic susceptibility ( ?LF ) for soil samples that have not been used as agricultural land ranges in the range of 923.8 x 10-8 m3/kg to 1239.8 x 10-8 m3/kg. While the magnetic susceptibility values for soil samples ranged former agricultural land in the range of 546.6 10-8 m3/kg to 848.9 10-8 m3/kg. Based on the results of magnetic susceptibility measurements, its seen a decline in the value of magnetic susceptibility on former farmland soil using chemical fertilizers. Soil samples in this study is dominated by independent frequency SSD and MD grains based on the value of frequency -dependent magnetic susceptibility, c FD ( % ) were < 3 % .Key words: magnetic susceptibility, farmland, chemical fertilizers, frequency dependent magnetic susceptibility, cFD (%)

Mostly, teaching materials merely focus on formulas and theories, yet there has not been found any teaching materials oriented to Qur'an. Due to that reason, it is significant to provide materials enabling students to learn independently, especially, those correlating the physics materials with Qur'an. Therefore, this study aimed to produce students' worksheets of physics, known as LKPD, correlating Qur?an with Guided Inquiry to achieve the students? competencies, particularly, in the topic of equilibrium and rotational dynamics. This study employed the Research and Development design with the 4-D research model consisting of four stages, namely defining, designing, developing, and disseminating. This LKPD also contains six stages of Guided Inquiry, namely orientation, formulating problems, formulating hypotheses, collecting data, testing hypotheses, and formulating conclusions. Every stage of Guided Inquiry engages the Qur?an verses with the material. The findings showed the validity of LKPD was at 88% categorized as very valid. The questionnaires resulted 88% of teachers and 70.3% of students categorized as very practical and practical. The average post-test score for students? competence (82.45) is higher than the average pre-test score (49.64) and N-gain of 0.77 considered high and effective. In conclusion, the physics students' worksheet or LKPD which employed Guided Inquiry corresponding with Qur?an is considered valid, practical, and effective to promote students in learning physics.
