Abstract

Physics is a scientific field that studies a lot of abstract concepts which in the learning process demands a lot of ability to do mental depictions of something being studied. This study aims to describe the cognitive learning outcomes of students who apply PhET virtual laboratory and Real Laboratory on elasticity and Hooke's law. The subjects of this study were two classes totaling 70 students of class XI MIPA SMA Negeri 2 Pekanbaru. This research uses quasi-experimental research with a quantitative approach and tests (pre-test and post-test) as data collection methods. To analyze the data, several analyzes were used, namely descriptive analysis (Absorption Power, Learning Effectiveness and Normal Gain Test) and Inferential analysis (t-test). The results showed that the average value of the pre-test class that implemented the PhET virtual laboratory was 44.40 and the post-test score was 76.20, while the average value of the pre-test class that implemented the Real Laboratory was 43.80 and the score was 43.80, post-test was 84.20. The absorption category achieved by the two classes is in the same category, namely good and the effectiveness of the learning used is in the effective category. This shows that the learning outcomes of the two classes have increased with the average gain test being classified in the moderate criteria, namely 0.54 and 0.70. In summary, the use of PhET Virtual Laboratory and Real Laboratory has a significant effect on students' cognitive physics learning outcomes. PhET Virtual Laboratory and Real Laboratory are effective for teaching Elasticity and Hooke's Law as an alternative to physics experimental activities.

Abstract

The effect of dispersion will interfere with the signal transmission. Several ways can be done in compensating the dispersion such as by utilizing dispersion compensator fiber (DCF) or chirp fiber Bragg grating (CFBG). The dispersion compensation schemes with DCF are expensive and it also causes nonlinear optical effects, meanwhile, the CFBG can reduce costs and promise better results. In this study, an Apodization Chirped Fiber Bragg Grating (ACFBG) has been developed as a dispersion compensator with Optisystem with non-return to zero (NRZ) 20 Gbps. It is found that the Gaussian Cubic-CFBG apodization with a size of 90 mm had the highest Q-factor evaluation of  20,776 dB for a 250 km dispersion compensation scheme. this result is much larger than the previous CFBG dispersion compensation scheme. This study also confirmed that the Gaussian Apodization was the best profile compared to Tanh Apodization, from the evaluation of the Q-factor, Tanh cubic-CFBG only obtained a Q-factor of 9.6 dB. Certainly, the high performance of ACFBG as a dispersion compensator is very useful to support optical communication systems

Abstract

The purpose of this study was to analyze the social competence of science teachers. It was conducted in 22 SMP Negeri Dumai City with a population of 86 science teachers in public junior high schools. The research sample was 71 science teachers calculated using the Slovin formula at an error rate of 0.05%. The instrument used in data collection was a questionnaire that was pre-tested to 30 science teachers (15 science teachers at SMPN Dumai City and 15 science teachers at SMPN Duri). From the 30 items of the questionnaire statement that were tested, the validity of each item was calculated with the product moment correlation with the help of the SPSS version 23, 29 valid items were obtained. Calculation of instrument reliability using the Cronbach Alpha formula was obtained 0.931 very reliable category. Furthermore, the social competence questionnaire instrument for science teachers who had met the validity and reliability requirements was used to collect data for the research sample of 71 science teachers at public junior high schools in the city of Dumai. The results of descriptive data analysis showed that the social competence of science teachers at the Dumai City Junior High School was 54.90% (39 science teachers) in the medium category, 25.30% (18 science teachers) who had high category competence and 19.70% (14 science teachers) out of 71 science teachers in the low category. Thus, the social competence of science teachers in Dumai City Junior High School is mostly in the medium category.

Abstract

Fiber Bragg grating (FBG) sensors have limitations in measuring high and extreme temperatures because in general FBG sensors are made of silica fiber, which at high temperatures can interfere with the mechanical performance of the materials. In this paper, we propose an S-FBG (Sapphire Fiber Bragg Grating) sensor which is resistant to extreme environmental influences and high temperatures. By developing S-FBG to measure high temperatures, it is found that S-FBG has high sensitivity, every 10C change is obtained and the Bragg wavelength shifts as far as 30.24 nm, this result is greatly influenced by the thermo-optic coefficient, and the coefficient of expansion-thermal. The design also evaluates the Gaussian apodization profile to improve sensor accuracy in monitoring temperature.

Abstract

We have observed a numerical simulation of the PCF-SPR sensor detecting alcohol concentration at low temperatures. The investigation was carried out using the finite element method on the PCF-SPR geometric structure. We use a simple geometry structure of the sensor by using fused silica and gold as the sensor’s core and plasmonic material. Observations were made in the alcohol concentration range of 15%, 40%, 60%, and 70%. In the literature, we find the refractive index of each alcohol concentration and input its value into the proposed sensor. The proposed sensor shows that the sensor has a sensitivity in detecting alcohol concentrations at low temperatures of 91 nm/%. In the end, we obtained the optimal sensor components and the sensor can detect the alcohol concentration at low temperatures
