Abstract

The effects of carbonized temperature on the briket-based properties of rice husks and coconut shells. This study aims to determine the effects of carbonization on brique-based, rice husk and coconut shell which include water content, ash content, volatile matter content, and calorific value. The research method used in this study is purely experimental within a process of carbonization of rice husk divested by free variables at temperatures of 300°C, 400°C, and 500°C for 30 minutes and carbonized coconut shells with a constant variable temperature of 500°C for 2 hours. Measures of a rice chaff and coconut shell of 200 mesh. Making briquettes with fixed variables, namely the composition of rice husk charcoal: coconut shell charcoal = 1: 3 (5 g:15 g) and printed using a pressure of 99.91 kPa. Then do the testing of water content, ash content, volatile matter and heating value. Test results on each type of briquettes with variations in the temperature of 300°C rice husk carbonization and 500°C coconut shell, 400oC rice husk carbonization temperature and 500°C coconut shell and 500°C rice husk carbonization temperature and 500°C coconut shell temperature were respectively obtained for 0.78% water content , 0.56% and 0.41%, ash content of 42.40%, 35.50% and 32.70%, volatile matter of 26.19%, 24.92% and 24.38%, and calorific value amounted to 3381.70 cal/g, 4261.50 cal/g, and 4621.50 cal/g.

Abstract

This research is an experimental research with the type of Ex Post Facto research, which aims to analyze the effect of learning interest on achievement motivation, learning interest on critical thinking skills, emotional intelligence on achievement motivation, emotional intelligence on critical thinking skills. Using a casual survey method with Path Analysis techniques. Based on the results of expert assessments, it is declared valid and suitable for use. Furthermore, the instrument that was declared valid by the expert was then tested on class XII students, after the instrument was tested and a valid instrument was obtained, then the valid instrument was tested on class XI students. Based on the results of this study, it was obtained that the critical thinking skills of students in Physics were in the moderate category, while Learning Interest, Emotional Intelligence, and Achievement Motivation were in the high category. From the results of the Path Analysis test between variables, it was obtained that there was an insignificant influence of interest in learning Physics on achievement motivation, there was an insignificant influence between interest in learning on critical thinking skills, there was a significant influence between emotional intelligence on achievement motivation, there was an insignificant influence between emotional intelligence on critical thinking skills, there was an insignificant influence between achievement motivation on critical thinking skills.

Abstract

The tipping bucket rain gauge is an automatic rain gauge that can measure rain intensity in mm/hour. Accurate measurement of rain intensity requires calibration of the rain gauge to ensure traceability. Calibration of a tipping bucket rain gauge is related to the volume of water as a calibration medium and time so as to produce a discharge that can be converted into rain intensity. Technological developments can make tipping bucket rain gauge calibration automatic by utilizing an Arduino Mega2560 microcontroller, a load cell and a simple water sensor based on the LM393 comparator IC, and combined with a compact design printed using a three-dimensional printer so that it can be used for ex-situ calibration. The data produced by this tool can be downloaded via the application that was built and produces a file in Excel form.
