Abstract

In this research, the application of Giant Magnetoresistance sensor AB001-02 series for mass measurement using ATMega328p microcontroller has been developed. Characterization is done by bringing a neodymium magnet closer to the GMR sensor. From the tests conducted, it is known that the farthest range detected is 3.5 cm with the optimal sensitivity area in the range of 0 - 1.5 cm. Based on the tests that have been carried out, changes in mass result in spring displacement (∆x). Displacement causes changes in the magnetic field read by the GMR sensor so that the output voltage of the GMR sensor changes. The greater the mass given, the greater the output voltage of the GMR sensor. The results show the sensitivity of the GMR sensor on mass measurement is 0.0816 Volt/Kg and has a measurement range of 0 - 4.3 Kg with a resolution of 100 g.

Abstract

This research aims to determine the sensitivity of the sensor as a low temperature sensor from the Ni-coated Cu coil with electroplating technique. The deposition parameters are set, namely the electrolyte solution by dissolving NiSO4, NiCl2, H3BO4 and distilled water, voltage 4.5V, electrode distance 4 cm, electrolyte temperature 60 ° C for 4 minutes. The sensor sensitivity test was carried out by varying the temperature from 0˚C to -150˚C by inserting the sensor in a liquid nitrogen thermos and lifting it to its original position. Acquisition of temperature and voltage data at any time was carried out with the help of a transducer. Based on the results of the study, the Voltage-Temperature curve shows that the sensitivity value obtained by the Cu coil is S(T) = -1E-06 T - 5E-05 and the Cu/Ni coil S(T) = -4E-06 T - 0.0002. The results of the T=-200 ˚C projection show that the sensitivity value of the Cu/Ni coil has a greater value than the Cu coil. The Cu coil shows a value of 0.00035 while the Cu/Ni coil is 0.0014. So Ni has an effect on increasing the sensitivity of the Cu coil as a low temperature sensor.

Abstract

Viscosity experiment is one of the materials given in the Basic Physics experiment course at FPMIPA UPI which aims to measure the viscosity level of a liquid using the Stokes law method or the ball viscosimetry method. Previously, oil was often used as a test material, but its thick color made observation of the ball in the liquid difficult, especially when using software such as trackers that require visual clarity. The purpose of this study was to examine the alternative of using teepol as a test material. The research method applied is the experimental method of replacing oil with teepol. From the results of experimental data collection using Stokes' law, with 4 balls of different diameters, the viscosity value of teepol ranges from 3.36 to 4.55 kg/ms. The consistent, reliable and valid measurement results show that teepol is reliable for viscosity experiments.  In conclusion, the use of teepol as an alternative material in viscosity experiments offers an innovative solution to the visual challenges faced when using oil.

Abstract

The purpose of this study is to ascertain how changes in the volume proportion of banana stems affect the composite's mechanical characteristics and microscopic structure.  Banana stem fibre served as a natural reinforcement in this investigation together with a polyester matrix.  The selection of banana stem fibre was based on its broad availability and possible mechanism.  The hands lay-up approach is used in this study.  The volume proportion of banana stem fibre was varied from 0% to 25% in order to mould each sample into a composite.  A two-hour alkalisation treatment with 5% NaOH was applied to banana stem fibre. A Universal Testing Machine (UTM) was used to assess the samples' tensile strength, and an optical microscope was used to examine their microstructure.  According to the study's findings, the tensile strength values of composites with volume fractions of 0%, 10%, 15%, 20%, and 25% were 5.9 Mpa, 11.9 Mpa, 8.9 Mpa, and 7.9 Mpa, respectively.  It is evident that the sample with the best tensile stress value, 11.9 Mpa, has a 15% banana stem volume fraction.

Abstract

This study aims to improve the accuracy of resonance analysis in closed pipe resonance through the measurement of quality factor (Q) and effective air column length. The method employed involves an automated system based on Arduino, equipped with an HC-SR04 sensor to measure distance and a KY-037 sensor to detect sound amplitude, integrated with Python-based data analysis for determining the resonance frequency. The measurement results show that the use of effective length with tube radius correction and improved frequency determination methods can reduce error from 1.33% to 0.24%, as well as decrease the standard deviation from 0.45 cm to 0.37 cm. Furthermore, quality factor analysis indicates an increase in the average value from 20 to 31, suggesting that the implemented resonance system and analysis method provide more accurate results, despite increased variability. Overall, the system successfully delivers more precise measurements in the analysis of resonance characteristics in closed organ pipes, particularly in relation to energy dissipation.

Abstract

This study explores the efficiency level of two experimental methods for determining the coefficient of restitution, which have been widely conducted in previous research. Using smartphones as tools in physics experiments, the coefficient of restitution can be determined through visual analysis (camera) and sound sensors to detect collisions. Phyphox is used to record time intervals and the height of the ball after impact based on the sound of the collision with the floor. Additionally, Tracker is employed for visual motion analysis of the object during the collision. The coefficient of restitution calculated using Phyphox yielded a value of 0.894 ± 0.017, while Tracker provided a value of 0.888 ± 0.014. The results indicate by reviewing the percentage error between the two methods (0.715%), Phyphox and Tracker can provide accurate data for determining the coefficient of restitution, making them effective and efficient physics experiment-based learning tools in schools.

Abstract

The need to improve students' argumentation skills through phenomenology learning approaches encourages efforts to map scientific argumentation skills. the research aims to determine students' argumentation skills on static fluid. Qualitative research with survey method using questions about static fluid phenomena in everyday life. random sampling obtained 33 students from one of the State High Schools in Malang Regency as samples in the study. Data were analyzed by mapping the level of scientific argumentation skills. The results showed that students' argumentation skills were spread from level 1 to level 4 with the majority at level 2. At this level, students are generally able to provide claims consisting of data and reasoning. This achievement shows that students' scientific argumentation skills are relatively low. Future research can design innovative models and media to improve students' scientific argumentation skills.
