This study aims to determine the quality figures of 21st century-based multi-representation assessments on linear motion material. Type of this research is Research & Development (R&D). Data were analyzed using an assessment validity test by an expert and empirical assessment quality test to obtain quality figures in the form of validity, reliability, level of difficulty, and discrimination power. The results of the preliminary field testing analysis showed 58.33% items were declared valid and 41.67% items were declared invalid. Test items have very high reliability with a value of 0.877. The proportion of the level of difficulty is not ideal, that is equal to 58.33% of questions categorized as difficult and 41.67% of questions categorized as sufficient. The discrimination power of the questions is 8.34% of the questions in a good category, 22.22% are sufficient, 58.33% are bad, and 11.11% are very bad. The result of main field testing, 69.44% items were declared valid and 30.56% items were declared invalid. Test items have high reliability with a value of 0.879. The proportion of the level of difficulty obtained in the main field testing is also not ideal, which is 56% of the difficult category and 44% of the sufficient category. The discrimination power consist of 32% good, 40% were sufficient, and 28% were poor.

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.

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.

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.

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.
