The design of this study was pre-experimental design with One Group Pretest-Posttest Design. This research was conducted in Mojokerto, East Java, Indonesia. Thirty five 11th grade high school students and one teacher participated in this study. This study applied the certainty of response index (CRI) with Two-tier Diagnostic Test to determine students’ misconception. An analysis of differences in the average of misconception between pretest and posttest and also normalized gain analysis had been performed to find out the effectiveness of guided discovery learning implemetation towards students’ misconception reduction. The treatment was declared effective if the average of misconception in pretest was greater than the postest and the normalized gain was negative, which meant there was a decrease in misconception minimum in the moderate category (<g> ⩽ -0,3). The results showed that in the initial tests the 3 highest students’ misconceptions occured on the concepts: wavelength, wave velocity and the nature of the wave. But the implementation of guided discovery learning was able to reduce students’ misconceptions significantly. Based on the statistical analysis of T test, it was found that tcount > ttable with α = 0.05 with 1.96 > 1.71. This meant that there were significant differences in average misconception. Through gain analysis, it is also known that <g> = -1,13 where the average misconception at pretest is 53,33% to 19,55% for posttest. This decrease was included in the high category. According to these analysis results, the application of the Guided Discovery Learning model using Virtual Lab. PhET was able to reduce students’ misconceptions.

Published: December 2019

Abstract
Providing STEM (Science Technology Engineering Mathematics) education and apply it in learning is influenced by teacher‘s knowledge and attitude towards The purpose of this study is to determine the teachers and lecturers’ attitudes, knowledge, and application of STEM education. Data were collected from the responds of science lecturers and teacher toward a set of STEM instuments. The results point out that respondents strongly agreed to apply STEM education in learning and are sure that students would get added value when applying STEM education. Regarding aspect of knowledge, more than 50% of the respondents have adequate knowledge of the term STEM although more than 50% of the respondents do not grasp the idea of weaknesses and advantages of implementing integrated STEM. Furthermore, 76.2% of respondents tried to implement integrated STEM when teaching with a percentage between 26%-75%. The application of integrated STEM involving the discipline of engineering has a lower percentage of application than integration with other disciplines. The findings also report that obstacles to the implementation of integrated STEM are the ability to apply the mathematics concepts, technological tools available, the duration of learning time, and the process of connecting between disciplines in STEM. This research implies that there is a need to increase the understanding the interrelationships between aspects of STEM, and need to develop STEM-based learning models to support the application of integrated STEM in Science learning.

Published: December 2019

Abstract
Gamma energy spectrum is a way to confirm the type and content of radioactive nuclides in substances. In order to obtain effective data of gamma spectrum, it is necessary to analyze the data of gamma spectrum obtained by the detector. Nevertheless, due to the influence of statistical fluctuation and gamma generated by the environment itself during the measurement of gamma spectrum, the obtained gamma spectrum is not accurate enough as a result of needing spectral analysis of gamma spectrum, and noise reduction can make the spectral data smoother. Therefore, this paper studies the noise reduction algorithm for gamma spectrum analysis, analyzes the design and application of different algorithms in the process of noise reduction, and summarizes the advantages and disadvantages of this algorithm and others.

Published: December 2019

Abstract
In order to select a more suitable anesthetic for the breeding and transportation of Sinogastromyzon szechuanensis, we used different concentrations of anesthetic eugenol (0, 6,12,18,24,30 mg•L−1) to test the effects of the respiratory and metabolic on Sinogastromyzon szechuanensis with an average mass of (2.029±0.26) g under the water temperature (18±0.5) °C. Based on regression analysis method, the regression equations of oxygen consumption rate, ammonia removal rate and temperature were calculated. (R2> 0.99). Oxygen consumption rate and ammonia removal rate were calculated and compared by One-Way ANOVA (Turkey method) using SPSS 25.0 software. The multiple comparison results revealed that when the mass concentration of eugenol reached 24 mg•L−1, it could significantly reduce the oxygen consumption rate and ammonia excretion rate (p<0.05). With the increase of eugenol concentration, the oxygen consumption rate and ammonia excretion rate of the Sinogastromyzon szechuanensis first increased and then decreased. Under the influence of eugenol, the oxygen consumption rate and ammonia excretion rate of Sinogastromyzon szechuanensis were increased with the increase of temperature (p<0.01). When the water temperature is 14-26°C, the oxygen-nitrogen ratio is 8.0-19.4, and the temperature is positively correlated with the oxygen-nitrogen ratio. It is concluded that eugenol with a mass concentration of 24 mg•L−1 can make Sinogastromyzon szechuanensis enter the stage of anaesthesia II (sedation), so this concentration is recommended as the anesthetic dosage for transportation, and the anesthetic effect at low temperature is more obvious.

Published: December 2019

Abstract
In order to improve the radon adsorption efficiency of activated carbon and provide a reference for reducing the cost of radon purification, the radon adsorption experiment of activated carbon under different gas superficial velocities under the active adsorption mode was studied to measure the radon adsorption quantity of activated carbon. The radon adsorption quantity of apricot shell activated carbon and coal-based activated carbon did not change significantly with the increase of the gas superficial velocity. When the gas superficial velocity increased from 0.9cm/s to 2.0cm/s in turn, the radon adsorption quantity of coconut shell activated carbon did not change significantly. The radon adsorption quantity of coconut shell activated carbon increased first and then decreased when the gas superficial velocity increased from 2.0cm/s to 3.1cm/s. When the gas superficial velocity was about 2.7cm/s, the radon adsorption quantity of coconut shell activated carbon reached its peak value. 2.7cm/s can be selected as the optimum gas superficial velocity for the radon adsorption of coconut shell activated carbon.
