<![CDATA[Hasil observasi awal dari penelitian ini adalah hasil wawancara pengetahuan yang diperoleh peserta didik dalam kelas hanya bertahan sesaat dalam kelas dan tidak mampu menghubungkan materi pelajaran dengan kehidupan nyata diperkuat juga dengan hasil ulangan yang rendah dimana hanya ada 7 orang (19,4%) yang tuntas dari 36 peserta didik dan ada 29 orang (80,5%) tidak tuntas. Prosedur penelitian tindakan kelas ini menggunakan 2 siklus dan akhir setiap siklus dilakukan ulangan harian untuk melihat peningkatan motivasi dan hasil belajar. Rata-rata ulangan harian pada siklus I adalah 65,11 kategorinya cukup, 14 peserta didik tuntas (38,88%) dan 22 peserta didik belum tuntas (61,11%) dan pada siklus II adalah 78,47 kategori baik 33 peserta didik tuntas (91,7%) dan 3 peserta didik belum tuntas (8,3%).

<![CDATA[The most commonly used method for measuring the density of liquids is based on Archimedes' law. Lubricating oil generally has a defined density standard to show the quality of the oil. The purpose of this study is to determine oil density simply by applying Archimedes' law. This research was conducted in three steps. First, the measurement of the empty pycnometer. Second, the measurement of the pycnometer mass containing distilled water and oil. Third, measurement of copper mass in the medium of air, distilled water and oil. From the results of measurements and calculations, the obtained density of distilled water is (0.995 ± 3,582 x 10-4) gr/cm3 whose value is very close to the value of 1 gr/cm3 so that the distilled water used in this study is suitable as a reference/standard in finding volume copper; oil density is (0.868 ± 2.14 x 10-3) gr/cm3 whose value is very close to the value of oil density measured and calculated with a pycnometer of (0.875 ± 4.637 x 10-4) gr/cm3.]]>

<![CDATA[This study aims to examine the effect of experimental method on student learning motivation and student learning outcomes on rectilinear motion material in grade X at MAN Kendal. This is a quantitative research with a sample of 34 students of class X MIPA 4 as an experimental group and 32 students of class X MIPA 2 as a control group. Data collection techniques using test, questionare, observation, interview, and documentation. The experimental class is given learning using experimental methods and control classes using conventional methods. The hypothesis was tested using t test and simple linear regression. The results of hypothesis test show that learning motivation of the experimental class students is higher than the control class and learning outcomes of the experimental class are better than the control class. Based on the results of data analysis, it was concluded that there was a correlation between the experimental method of student motivation and learning outcomes.]]>

<![CDATA[Research has been conducted aiming to determine the distribution of coal below the surface in Tulungagung Regency. The survey conducted in this study used a Wenner configuration resistivity geoelectric survey. Retrieval of geolithic resistivity data in the field of four trajectories. The results of data collection in the field oneach track are processed using 2D modeling in Res2dinv software. The results of the processing of the two-dimensional modeling are then interpreted. The structure of rock layers containing coal is shown by a yellow, red to dark purple scheme with a resistivity value of 75-350 ohm meters on the inside varying from 0 meters to 6.91 meters below the surface, spreading erratically and patching on each track.]]>

<![CDATA[Telah dilakukan penelitian dengan menggunakan metode gayaberat untuk mengidentifikasi struktur bawah permukaan di Kawasan Kota Lama Semarang sebagai survei awal untuk keperluan mitigasi bencana. Pengolahan data gayaberat untuk mengidentifikasi struktur bawah permukaan dilakukan melalui beberapa tahapan. Tahap awal dilakukan dengan koreksi awal berupa koreksi pasang surut dan koreksi apungan, kemudian dilakukan koreksi lanjut hingga didapat kontur anomali Bouguer lengkap. Melalui anomali Bouguer lengkap dapat dipisahkan anomali gaya berat regional dan residual. Pemisahan anomali regional dari anomali Bouguer dalam penelitian ini menggunakan metode moving average (perata-rataan bergerak) sedangkan anomali residual didapatkan dengan cara mengurangkan anomali Bouguer dengan anomali regional. Pemisahan anomali regional dan residual penting untuk dilakukan pada penelitian identifikasi struktur bawah permukaan untuk menginterpretasikan struktur geologi dan mendapatkan target yang dicari. Nilai anomali regional di Kawasan Kota Lama Semarang antara 28.0 mGal ? 28.4 mGal sedangkan untuk anomali residual memiliki antara 31.6 mGal ? 32.8 mGal.]]>

<![CDATA[Technology that is increasingly developing produces equipments in the form of information, communication, production, transportation and entertainment facilities. Most of the equipments produce noises. Noise can be reduced by using acoustic dampers. This study aims to determine the potential for sound absorption from rice husks and straw as natural acoustic materials. Materials used include rice husks, rice straw, and resin. 12 cylindrical samples were made. Samples that have been made are tested using a sound absorption measuring instrument that is the impedance tube to measure the value of the sample sound absorption coefficient. The test results show the value of the sound absorption coefficient (?) can be influenced by the thickness. At a frequency of 500 Hz the value of the sound absorption coefficient (?) for each sample is 0.034dB; 0.030dB; 0.030dB; 0.027dB; 0.026dB; 0.027dB; 0.025dB; 0.025dB; 0.025dB; 0.024dB; 0.024dB; 0.023dB; 0.023dB. The sample material is good in research on materials 1 and 2 which have a sound absorption of 0.034 dB and 0.030 dB.]]>
