Abstract

The slope stability angle of the surface landslide stability depends on the friction coefficient between the rock particles in the area. Measurement of slope stability is very useful for the safety of miners in mining areas. Measurement of slope stability is based on the friction coefficient. Measurements are made with a friction coefficient measuring instrument that has been designed and tested. Rock samples were taken at 3 rock mines around Mount Pengsong in West Lombok Regency. The measurement of the friction coefficient was carried out at the Physics Laboratory of the University of Mataram. The measurement results of the friction coefficient are then converted into slope stability angles. The results show that the slope stability angle in the mountains around the rock quarry around Mount Pengsong has a maximum value 5,71 degree of dry sample and 81,0 degree of moisture sample.

Abstract

This study aims to identify the misconception profile of prospective physics teachers (respondents) on the material of temperature and heat. This research is quantitative descriptive research. As many as 25 prospective physics teachers as respondents in this study. The research data was taken using a three-tier test instrument in the form of multiple choice questions with open reasons. The results showed that as many as 58.73% of respondents experienced misconceptions and only 30.82% of respondents understood the concept. Most of the misconceptions occur in the concept of thermal equilibrium. As many as 61.90% of respondents experienced misconceptions about this concept. In addition, many misconceptions occur in differentiating the concepts of temperature, heat, and thermal energy. A total of 59.53% of respondents experienced misconceptions about this concept. the average respondent has not understood the substance of the difference between the concepts of temperature, heat, and thermal energy. Many of them equate to the concept of heat and thermal energy of an object. respondents also do not seem to be very able to distinguish the boundaries between the concept of temperature and the concept of thermal energy.

Abstract

A tensimeter is an instrument works with concept of physics used to measure blood pressure. The measured blood pressure is the relative pressure between the pressure inside the blood vessels compared to the pressure of the atmosphere. Blood pressure measurements using a digital tensimeter are much more acurate than measurements using a aneroid tensimeter. Measurements with an aneroid sphygmomanometer at a hospital in the city of Mataram showed a measurement error up to 20 mmHg compared to a digital sphygmomanometer. Source of error consist of two main factors ie. Instrument error and human error. From this research it was found that measurements using a digital sphygmo-manometer are more accurate, so the use of this type of sphygmomanometer is highly recommended for clinical measurements in hospitals and health hospitals.
