Abstract

Scientific literacy can prepare quality human resources who can develop the ability to think logically and creatively, solve problems, be critical, master technology and be adaptive in the face of change and face the times. A vital component to improving students' scientific literacy is understanding the Nature of Science (NoS), which must be emphasized in science learning. The purpose of this study is to obtain a comparison of content and explain aspects of NoS in science textbooks in Indonesia and Singapore. The research approach used is descriptive qualitative with content analysis design. This research focuses on science books for Junior High School Class IX Semester 1 Curriculum 2013 Revised Edition 2018, Integrated Science Books for Junior High School Class IX Curriculum 2013 Revised Edition 2018, and Lower Secondary Science Matters Textbook Volume B 2nd Edition 2013. The data collection techniques are by reviewing documents with non-test instruments in the form of observation guidelines for assessing textbooks based on the NoS aspect developed by Abd-El-Khalick et al., (2008). The data analysis technique uses the fixed comparison method by Moleong (2014). The results obtained are that the textbooks from the two countries have represented several relevant aspects of NoS. Still, the theoretically-driven elements have not been found in the three books, and the existing components have not been well described. Science textbooks in Singapore get a higher score than science textbooks in Indonesia. Still, the availability of the NoS aspect of science textbooks in Indonesia is more than that of science textbooks in Singapore.

Abstract

The landslide disaster that killed people occurred due to public ignorance of the type of soil prone to landslides. Several efforts have been made to create prototype tools for soil movement detection. However, researchers using the Internet of Things (IoT) technology are still limited. The IoT allows for the transmission of data over an internet connection, is always connected, offers remote control capabilities, and data sharing. All of this served as the prototype design of foundation for the soil movement detection. A light-based proximity sensor is used in system, and its output is represented as a movement of the soil on an inclined plane. F furthermore, the data used as input for the NodeMCU ESP8266 microcontroller is linked to the internet. The output is an HMI in the form of an LCD monitor that displays the soil movement measurement. The simulation of disturbances in an inclined plane is done differently depending on the frequency and duration. Moreover, monitoring is carried out by transferring processed data to the Blynk platform, which is subsequently shown in real time via the Blynk Android application. The test results of the tool used three distinct samples, as well as varied disturbance frequencies and durations. With the soil samples, the biggest movement data was 5cm achieved at a disturbance frequency of 5Hz and 40 seconds duration. The largest movement data for sand samples was 11cm at a disturbance frequency of 3Hz and 50 seconds duration, followed by largest movement data for sand soil mixture samples was 8cm at a disturbance frequency of 5Hz and 50 seconds duration. People should not reside on slopes, especially if the soil's primary component is sand.
