The experiment supports the STEM approach based on real experiments and especially if it is low-cost equipment. In this study, a preliminary study was conducted on the proton precession magnetometer (PPM) design, which will be used as a teaching aid for STEM learning to explore the atomic nucleus and as a magnetometer to determine the strength of the earth's magnetic field accurately. The PPM signal is susceptible to changes in the external magnetic field so that external magnetic disturbances such as electric currents and ferromagnetic materials in the building produce noise. So the measurements are carried out outside the building. The sensor uses two coils that are polarized opposite each other to eliminate the noise from the outside. In addition, analog filtering is also designed in a bandpass filter only to pass the desired frequency range. Since the PPM signal is tiny, the coil is coupled with a suitable capacitor to amplify the signal radiated by the protons through an inductor-capacitor resonance effect at the desired target frequency. Signal PPM measurement results in the time domain can be displayed, although visually, it is difficult to recognize because it is immersed in noise. However, when heard with the human ear, the distinctive sound of the PPM signal will be clear for about 3 seconds after applying polarizing current to the coil. Waves in the time domain can be converted into the frequency domain using audacity 3.0.2 software. The peak frequency obtained is 1914 Hz. Based on the values of these frequencies, based on the Larmor formula, the value of the earth's magnetic field obtained is 44.97 uT.","PeriodicalId":405480,"journal":{"name":"2021 2nd SEA-STEM International Conference (SEA-STEM)","volume":"156 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122614651","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We conducted a quantitative study with a cross-sectional survey design. Data were collected from 232 secondary school teachers and analyzed by ANOVA. This study suggests that, to some extent, demographic variables do not play a significant role in teachers' level of teachers' digital literacy. It was found that, among demographic background variables examined in this study, only teachers' levels of education have a significant role in the level of digital literacy. It indicates that researchers and practitioners should take teachers' education level into account when they design and implement professional development on digital literacy.","PeriodicalId":405480,"journal":{"name":"2021 2nd SEA-STEM International Conference (SEA-STEM)","volume":"238 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123883317","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The simulated models can be used to understand the pre-eruption of volcanic behavior based on the change of resistivity responses measured on an active volcano. Four resistivity models of conduit states have been modeled using REBOCC MT forward modeling code. The models include a conduit with empty magma, the magma starts to accumulate in the conduit, the magma rises, and the conduit full of magma. The resistivity value of the empty conduit and the magma material was 10 Ohm-m and 50.000 Ohm-m, respectively. While the conduit is located within a volcano composed of three resistivity layers, i.e., 100 Ohm-m, 400 Ohm-m, and 1000 Ohm-m from the top to the bottom. The synthetic data responses generated by each model were used to analyze each state. The calculated transfer function of magnetotelluric data includes apparent resistivity and phase for TE-mode. Each data set were calculated in range of period 0.001, 0.01, 0.1, 10, 100, 1000 s. The results showed that apparent resistivity responses increase with increasing the magma height in the conduit. The simulated models can be used to predict the height of the magma before it would be reached the surface as a precursor of a volcanic eruption.","PeriodicalId":405480,"journal":{"name":"2021 2nd SEA-STEM International Conference (SEA-STEM)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116814125","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
