Abstract

Edupark is a park with a variety of rides and ecosystems that can be used as a learning tool. Ngarai Sianok, Bukittinggi is a national Geopark area that has a nature tourism vehicle and Minang Fantasy (MiFan) Padang Panjang Water Park is an artificial tourist game vehicle. In general, visitors to attractions only take advantage of the natural landscape or a vehicle to take photos, sports such as jogging, hiking, camping, family gathering or low impact outbound. Without them knowing it, there are many physics concepts in both natural and artificial games that can be used as learning resources by integrating into high school physics learning in the form of physics teaching materials or integrated in learning models. However, there are actually educa-tional values, especially the physical concepts contained in the game. The purpose of this study is to integrate Edupark Ngarai Sianok and MiFan Water Park because it remembers so many Physics concepts found in natural or artificial tourism. The process of collecting data through observation and study of literature. The results showed that Edupark physics could be integrated in learning physics according to the 2013 curriculum

Abstract

Students' critical thinking skills are still not optimal. One of the reasons is the use of teaching materials in the form of student worksheets that are not yet in line with the good student worksheet structure, do not yet contain the STEM approach, and critical thinking indicators have not been clearly illustrated in the student worksheet. The purpose of this study is to determine the validity of the LKPD, determine the practicality and effectiveness of using student worksheet Physics based on the STEM approach that can improve students' critical thinking. This type of research is research and development (R&D) using the Borg & Gall model which consists of the initial research and information gathering stage, planning, developing the initial product format, and initial trials. As the object of research is the Physics student worksheet based on the STEM approach. Data collection instruments used were expert validation sheets, practicality test sheets, and effectiveness test sheets. The effectiveness test uses an assessment sheet of learning outcomes tests and observation sheets of students' critical thinking. The data analysis technique used is the analysis of the validity of the Physics student worksheet, the practicality analysis of the use of the Physics student worksheet, and the effectiveness analysis of the use of the Physics student worksheet. Based on the analysis of the data that has been done, two research results can be put forward. First, the average value of the validity of the Physics student worksheet based on the STEM approach is 0.88 and this value is included in the valid category. Second, the average value of the practicality test for the use of Physics student worksheet by teachers and students respectively 91.44 and 84.14. This value shows the Physics student worksheet is in the category of very practical. Besides that, the use of Physics student worksheet based on the STEM approach is effective to improve students' critical thinking

Abstract

In general, the population in Indonesia is a farmer. This causes farmers to need information about the weather to carry out agricultural activities. One way to obtain information about the weather is to use the Rain Gauge instrument. In this study, the Rain Gauge instrument at LAPAN Kototabang from 2020 to 2021 was compared with the Optical Rain Gauge instrument. This research uses descriptive research with secondary data in the form of rainfall intensity data that has been measured on the Rain Gauge and Optical Rain Gauge from LAPAN Kototabang. This research was conducted to analyze the output data from the Rain Gauge and Optical Rain Gauge in the form of rainfall intensity, rainfall accumulation, and time. From the data analysis, two results can be stated from this research. First, the analysis of the rainfall parameter data that has been processed shows that the rainfall in Kototabang in January - October 2020 and 2021 has a high rainfall value. This causes the intensity of rainfall in Kototabang to be categorized as heavy rain. The two accumulations of rainfall in 2020 and 2021 in the Kototabang area are 497.031 mm and 0.602 mm using the Rain Gauge. While the measurement using Optical Rain Gauge rainfall intensity is 0.207 mm and 0.221 mm. This proves that the intensity of rainfall in 2020 is greater than the intensity of rainfall in 2021.
