Abstract

This study aims to develop an Android-based Al-Qur'an integrated physics learning media to improve preservice physics teachers' higher-order thinking skills and spiritual attitudes. The development of learning media uses the ADDIE model. Media and material experts assessed the feasibility of learning media through a validation questionnaire. The trial was carried out on 40 preservice physics teacher students. The validation results were analyzed using a descriptive technique. The analysis results show that the learning media developed is suitable for improving Higher Order Thinking Skills and the Spiritual Attitude of Preservice Physics Teachers. So, the Android-based physics learning media integrated with the Quran can be implemented for preservice physics teachers.

Abstract

CaCO3-doped Li4Ti5O12 was synthesized by solid-state method with sintering temperatures at 750 °C, 800 °C, and 850 °C. The source of CaCO3 was used from blood clam shells (Anadara granosa) with a content of 97.67%. The influence of sintering temperature on crystal structure and conductivity of CaCO3-doped Li4Ti5O12 are extensively studied. XRD results show there is no CaCO3 phase found, which indicates that the doping of Li4Ti5O12 with CaCO3 has been successful. The smallest crystallite size was obtained at a sintering temperature of 800 °C, which is 46.49 nm, which is beneficial for shortening diffusion length and facilitating the electron and ion transport, causing an increase in anode conductivity. The most optimal conductivity was obtained in samples with a sintering temperature of 800 °C with a conductivity of 2.46 x 10-4 S/cm. When the sintering temperature is increased to 850 °C, the particles tend to agglomerate and deteriorate the electrochemical properties.

Abstract

The performance of a thin layer of Cu/Ni as a cryogenic sensor is produced by electroplating at various angles with the aid of a 200G parallel magnetic field. Liquid nitrogen (LN2) is a low-temperature medium with temperatures varying from 0oC to -200oC. The characterization includes the sensor voltage range, sensor resistance, and sensor sensitivity. Thermocouple TCA-BTA -200oC to 1400oC is used as a temperature calibrator. The results showed that all sensors could measure the LN2 temperature in the range of 20oC to -200oC corresponds to the thermocouple's ability to measure up to -200oC. Each sensor has its advantages, but the sensor produced from coating each 3 minutes sample with an angle of 90o has the largest output voltage range up to 0.058 V, and the coating at an angle of 0o with the sensitivity level as a function of T is S(T) = 0.0051 - 0.002T, while the 3 minutes coating sensor with an angle of 60o has the smallest voltage range of 0.0439 V and sensitivity (1.88 ± 0.05) V/oC.

Abstract

This study aims to develop a photoelectric effect learning media based on Arduino Uno. The subjects in this study were students who took Modern Physics courses. The media development procedure uses the Borg and Gall model, which is limited to seven stages. The feasibility of the developed media refers to the results of the media expert's assessment, the level of practicality, and the effectiveness of the media. The test results show that the product's Planck constant of 6.62 × 10-34 J.s corresponds to the theoretical value. Three experts concluded that the learning media had a good level of feasibility to be used as an experimental tool. The level of practicality and effectiveness of the media showed good results. That is, practical and effective media to be used in experiments. So, it can be concluded that the Arduino Uno-based photoelectric effect learning media that has been developed is suitable for use in learning.

Abstract

Global warming is a phenomenon where the earth's temperature rises drastically. The temperature increase causes negative impacts on the environment globally. Bengkulu City, Indonesia, is situated with a growing population and land-use change that may cause temperature rise. This research aimed to analyze the temperature change in the land and sea area of Bengkulu City. To understand the local or global factors influencing temperature changes in Bengkulu City, we also studied the correlation between land and sea temperatures. The temperature data were obtained from BMKG and NOAA PSL. Firstly, we analyzed the temperature trendlines for the last 36 years. Then we evaluated the coefficient determination (R2) value to determine the correlation between sea and land temperatures. The results show that during the last 36 years, the sea temperature is increased by 0.40 °C, while the land temperature is increased by 1.07 °C. Moreover, we found a relatively weak correlation between sea and land temperature, with a 10.7% correlation. We argued that the increased temperature in Bengkulu City land is associated with land change use and rising population in the last few decades, which means the local factor affected the land temperature changes. On the other hand, global phenomena (IOD and ENSO) influenced sea temperature changes, which means the global factor affected the sea temperature changes. The rising land temperature is relatively high; hence it is necessary to understand better what parameters are causing temperature changes that may affect the physical environment in Bengkulu, Indonesia.
