Abstract

Penelitian ini bertujuan menghasilkan prototype media pembelajaran fisika berbasis micro controller NodeMCU. Prototype media pembelajaran fisika tentang Hukum II Newton telah dikembangkan dengan mengkombinasikan sensor IR obstacle, NodeMCU, dan sketch program Arduino IDE sebagai counter waktu dan papan track, kubus berlubang, katrol, benang, dan kepingan logam sebagai perangkat pendukung. Hasil eksperimen telah memperlihatkan nilai percepatan benda pada bidang licin lebih besar daripada bidang kasar. Hasil analisis grafik hubungan percepatan vs resultan gaya eksternal menunjukkkan berbanding lurus dan grafik hubungan percepatan vs massa benda menunjukkan berbanding terbalik. Dengan demikian dapat disimpulkan media pembelajaran fisika berbasis NodeMCU mampu memvisualisasikan, menjelaskan dan membuktikan Hukum II Newton. This research is aimed to develop a prototype of physics instructional media based on micro controller. Physics learning media about Newton’s second law prototype has been developed by combining IR sensor obstacle, NodeMCU, and sketch program the Arduino IDE as counter time, and tracking, block, pulley, rope and metal strip as support device. The experimental results show that the value of acceleration of the object on a slippery plane is larger than the rough plane. The results of the analysis of the acceleration and the resultant graph shows that the external force is directly proportional and a graph showing the acceleration vs the objects mass is inversely proportional. Thus we can conclude that Physics learning media based on NodeMCU is valid in explaining and proving Newtons II.

Abstract

This study is a literature review. The flipped classroom is the latest pedagogical model that has the potential to change the current traditional way of teaching. Flipped classroom emphasizes on learning activities that promote critical thinking and motivation among the students with the assistance of technology. The flipped classroom allows educators to move from ‘the sage on the stage’ to ‘the guide on the side. The basic and simplest form of flipped classroom is students are expected to watch digital resources prior to class. The students are then required to come prepared for class and perform hands-on activities that are related to the digital resources. The digital resources can be in any form such as video, audio or the internet. This allows teachers to spend more time with their students to carry out in class activities and allow immediate response to students’ needs. Student feedback on this pedagogy was generally very positive with many respondents considering it effective and helpful for learning. One of the biggest advantages mentioned by students is that they had the option to watch each video lecture as many times as required to be prepared for class.

Abstract

The C-RTD (Coil-Resistance Temperature Detector) output signal is an analog signal in the form of a direct voltage. This value changes with changes in RTD temperature. This analog signal can be read by users using a multimeter or similar device but does not directly indicate the RTD temperature. In order to obtain RTD temperature values, an additional device is required. In order to have a useful value and practicality, a device that can convert analog signals into values can be read directly by the user. The microcontroller was chosen as a used device. The selected microcontroller system is Arduino Uno because has been coupled with input and output ports so users only need to enter programs related to the system being created. In the other hand Arduino Uno by considering the low cost and practical. For the measurement system, the RTD output signal must be conditioned into a digital signal using the ADC so that it can be processed by the microcontroller. From testing instrument obtained that the system has been able to convert analog RTD signals into digital signals. The range of measurement is -176°C to  0°C with an accuracy of ± 0.20 / mV.

Abstract

This study aimed to determine the volume of traditional eucalyptus oil from distillation with variations in fluid flow velocity. The method of distillation was distillation with water (water distillation). The material was eucalyptus leaves. To determine the volume of eucalyptus oil produced by distillation, the distillation device was set at the height of the condenser to the source of flow fluid, which was at an altitude of 15 cm, 25 cm, 35 cm, 45 cm, and 55 cm. Variation in the height of the condenser would affect the fluid flow rate. The faster the fluid flow rate, the greater the convection coefficient so that it increased the heat transfer rate. This results in greater volume (capacity) of oil produced. From these experimental results, most volumes of eucalyptus oil obtained from the distillation was obtained at 55 cm of the height of condenser with 3.6 mLof oil volume.

Abstract

Abstrak- The study about fill factor and efficiency solar cell have been done with an automatic drive machine that rotates the surface of the solar cell following the movement of the light source from 0° up to 90° compared without automatic drive.  The test results are then implemented to determine the fill factor and efficiency in variations in light intensity. In this study, polycrystalline solar cell type (99 × 69) mm2, the Philips 100W/220V light bulb at a distance of 18 cm and the driving machine is controlled through an Arduino Uno R3 microcontroller. Data acquisition of current and voltage is carried out with the help of DCP-BTA current and VP-BTA voltage probes that are connected to the mini labquest transducer and displayed to a computer through loggerpro software. The result show that it has been successfully designed an automatic driver of a solar panel (99 × 69) mm2  with an Arduino Uno R3 microcontroller and a logger pro software as data acquisition software. The using solar cell automatically driven can improve the accuracy and precision of current and voltage readings so the fill factor might be increased up to 10% while the efficiency of solar cells does not change. Variations in light intensity can increase the fill factor and efficiency of solar cells. Fill factor and efficiency have an exponentially relationship to light intensity.

Abstract

The purpose of this research is to make the Cu/Ni thin layer as an alternative to basic RTD materials through electroplating methods assisted by magnetic fields. Electroplating was carried out with variation in deposition voltage ranging from 1 to 5 V. The results of this study indicate that the deposition voltage applied to the coating affects the thickness, sheet resistivity, and microstructure of the coating. Thickness increases with increasing deposition voltage. The diffraction intensity and crystal size tend to increase with increasing deposition voltage. The distance between Bragg planes after the coating is almost equal for all samples. The highest sheet resistivity was obtained in the coating sample with a 4-volt deposition voltage.

Abstract

The magnitude of the damping force of the mathematical pendulum swinging on a medium is usually proportional to the speed of the pendulum. In this research, the pendulum oscillation parameters oscillating on an air medium under the influence of a magnetic field of 1.8 G will be investigated. In the initial stage, the effect of the magnetic force on the damping coefficient of ferrite pendulum oscillations with an initial deviation of 15 degrees observed. Furthermore, the study continued with varying the angle of deviation from 5 degrees to 25 degrees. The results of the data fitting amplitude (xi) at various swing times (ti) are using to analyze the effect of the angle of deviation on the maximum amplitude. The results showed that for the deviation angle of 15o the coefficient of damping of the medium affected by the magnetic force was 0,0022 greater than the coefficient of air damping 0,00006. It affects the amplitude, which decreases faster than the pendulum amplitude without the influence of magnetic force. Variation in the angle of deviation also affects the amplitude of the pendulum. In the deviation angle below 10, the pendulum motion is more influenced by the magnetic force, whereas in the deviation above 10, the pendulum motion is more dominated by gravity.
