Abstract

This development research aims to produce a product in the form of a physics learning device with a problem based learning model on Momentum and Impulse material to improve students' higher-order thinking skills. The type of research is Research and Development (R&D) with a 4D model consisting of Define, Design, Develop, and Disseminate. The products developed are syllabus, online learning implementation plans, student worksheets equipped with PhET simulation instructions, and higher order thinking ability test instruments. Product validity was assessed by five validators with Likert scale analysis. Furthermore, the effectiveness of the device is determined from a limited trial to get the N-gain value. The results of the study based on the validator's assessment showed that the overall device developed had an average value of above 3.00 in the good category, then the average N-gain test results obtained a value of 0.34 in the medium category. Thus, it can be concluded that the development of problem based learning physics learning tools on Momentum and Impulse material is valid, and effective for improving students' higher order thinking skills.

Abstract

Fault is a displacement of the land with a certain direction and shift that triggers an earthquake. The existence of faults that are not visible on the surface can be identified by measuring the gravity anomaly above the earth's surface around the fault zone. This study was conducted with the aim of testing the effectiveness of radial derivatives for identification of fault zones, i.e the presence and positions of faults. Radial derivative is a horizontal derivative of the earth's gravity anomaly value with the radial direction away from a certain point that is considered as the radial center. Gravity anomaly data used in this study is synthetic data from computer calculations using the principle of forward modeling from a fault model. This model is in the form of a displacement of the rocks making up the soil at a depth of 100 m with a vertical shift direction of 4 m with an area of the fault zone 600 m x 600 m or 360,000 m2. This synthetic gravity data is then performed a radial derivative treatment. The results of this study show that radial derivatives are able to identify the presence and position of the fault.

Abstract

The presence of media in the learning process acts as a tool to prevent communication failures between teachers and students. This study aims to determine the effect of Annotated Illustration and PhET media on physics learning achievement on Dynamic Electricity material. The research method used in this study is a quantitative research method. While the type of research is experimental research. In this study, the PhET media was applied to the experimental class, while the Annotated Illustrations media was applied to the control class. The calculation results obtained = 3.836 and = 2.056 at a significant level of 5% and dk = 1 + 2. Therefore > , so that the null hypothesis (H0) is rejected or the alternative hypothesis (Ha) is accepted, which means that there is a difference in the effect of Annotated Illustrations and PhET on physics learning achievement on Dynamic Electricity material.

Abstract

This study aims to create a tool that can explain the event of the photoelectric effect on a laboratory scale. So that the existence of a tool that can explain the photoelectric effect will make it easier for users to study the nature of light as a particle. This tool is designed according to its function which will find out that the photoelectric effect event is not influenced by light intensity but is influenced by the frequency of a light source and the wavelength that illuminates a metal so that electrons will move from a negative source towards a positive voltage source. In the manufacture of these tools, a photodiode is used as a light sensor where when the photodiode is illuminated by light it will cause electrons to move from the cathode to the anode and make an electric current flow. To determine the stopping voltage, a voltage is applied to the cathode where the electrons are ejected. This stopping voltage for each wavelength is different. From the ongoing data retrieval, a graphic relationship is obtained between the ADC value and the Sensor Output Voltage. Thus, it can be concluded that, First, the voltage applied to the photodiode (cathode) is different for each color spectrum. Second, the output voltage obtained for each different wavelength, the less light intensity received by the photodiode, the smaller the output voltage value. The amount of output voltage for each LED color is different because the wavelength of each color is also different so the value is not the same.

Abstract

The impact of high-intensity noise can cause discomfort for crew and ship passengers. The noise is partly caused by the maine engine which is the biggest noise source. So it is necessary to find a solution on how to reduce noise and the impact of the noise. The purpose of this study was to determine the magnitude of the sound intensity and the effect of sound intensity on the comfort of the crew and passengers. The research was conducted using the Sound Level Meter (SLM) application. Measurements made in the passenger compartment and an average of 66.4 dB to 73.6 dB indicate that the ship's engine noise level when operating is included in the strong category according to Suma'mur's study, 2009, but does not cause deafness and hearing damage.
