Abstract

Incinerator is a device designed and used for burning non-metal solid waste using certain technology at high temperatures. Corrosion is damage or destruction of materials due to chemical reactions in the surrounding environment. High temperature and usage time in incinerators made from ASTM A36 is one of the factors for corrosion. The purpose of the research is to determine the effect of combustion time on corrosion value and the effect of high temperature combustion temperature on corrosion value. The research method carried out is an experimental approach by putting the ASTM A36 steel plate into the oven with the temperature to be used, namely 600 0C, 650 0C, and 700 0C with the heating time to be used for 3 hours, 5 hours, and 7 hours. The corrosion process is carried out by leaving it in the open air for 7 days and after that data collection and calculation of corrosion values are carried out. From the calculation results at a temperature of 600 0C and a heating time of 3 hours, the lowest corrosion value is 0.42020 mm/year and the highest occurs at a temperature of 700 OC and a heating time of 7 hours of 1.77629 mm/year.

Abstract

This research aims to determine the application of the flipped classroom learning model in improving the economic learning outcomes of students in class XI IPS I Islamic High School Bawari Pontianak. This research uses a quasi-experimental method on international cooperation material. In the learning process, researchers applied a learning model involving 25 students. Based on data analysis, it was concluded that: 1) The results of the research showed that the implementation of the flipped classroom learning model in class Pretest results/before students learn using the flipped classroom model 21.2. Meanwhile, the results of the posttest/after using the flipped classroom learning model were 76.4, so it can be stated that the flipped classroom learning model can improve student learning outcomes. 3) Based on the t-test, the pretest and posttest data show a significant effect of 0.000 ˂α 0.05 , which means that there are differences in learning outcomes before and after learning using the flipped classroom learning model. The effectiveness of the flipped classroom learning model has been proven to have a positive influence on student learning outcomes so that these results can be used as a reference for researchers or other teachers to be implemented and developed in their respective educational units.
