Abstract

This research focuses on analyzing the particle size of a thin Cu/Ni layer produced through electroplating by varying the input voltage. The Williamson-Hall method is used to determine the particle size of the layer, and an X-ray diffractometer is used to characterize the layer. The study finds that the particle size of Cu and Ni layers with different applied voltages has different values due to various factors. The optimum voltage for the Ni layer is found to be 7.5 volts, and its overall particle size is 4.13 × 10^(-10) nm, while the particle size of Cu is 5.00 × 10^(-9) nm. The applied voltage affects the particle size produced, and the research identifies an optimum voltage at 7.5 volts.

Abstract

The value of gravitational acceleration (g) varies across different locations depending on the distance from the surface to the Earth's center of mass. Additionally, the value of ggg is influenced by the data processing method employed. This study aims to determine the Earth's gravitational acceleration in the Banten region using a pendulum assisted by the Phet pendulum-lab simulation. The experiment was conducted using two methods: the average technique and the weighted average technique. For the average technique, the period was measured 10 times for a string length of 80 cm. For the weighted average technique, the period of the pendulum swing was measured at varying string lengths from 80 to 100 cm, with five variations, each measured 10 times. The results of the study showed that the gravitational acceleration determined using the average technique was 9.72 ± 0.28 m/s², while the weighted average technique yielded 9.78 ± 0.08 m/s². With the reference value of gravitational acceleration being 9.80 m/s², the weighted average technique successfully corrected the relative error from 0.82% to none. Moreover, the determination of gravitational acceleration using the weighted average technique produced more accurate results compared to the average technique. This study also confirms that the PhET simulation is an effective and reliable tool for measuring gravitational acceleration, particularly when physical experimental conditions are less than ideal. The weighted average technique significantly contributes to improving measurement precision, making it valuable for both physics research and education

Abstract

A simulation on the effect of probe deviation on sheet resistivity value (Rs) of Cu/Ni thin film was carried out in a home-made four-point probe (HM-FPP) type. This began by solving the Rs formula for normal probes, and then for wobbly probe when it was either A, or both A and B. The formula was implemented on a thin layer of Cu/Ni, which was a low temperature sensor material obtained from electrodeposition for 60s assisted by a 200G magnetic field at a current density of 0.07A/mm2. An electric current of 0.20118A was flown from probe A to D in order to produce a potential difference between probe C and D of 0.0005 volts. Furthermore, the distance between the probes was 5 mm and the deviation of each probe A and B were simulated from -0.5 mm to 0.5 mm. The maximum allowable limit for the relative error of Rs or SRs is 5%. The results showed that the ideal Rs value was 0.113 ohm/sq. Furthermore, for HM-FPP in which the wobbly probe only A, there is no problem encountered with the variation of the deviation because all SRs are less than 5%. For wobbly probes A and B, if they are on the same side of the center point of each probe, the maximum allowable deviation is 0.3 mm. The SRs for this case were 4.6%. However, if they are on different sides of the center point of each probe, the maximum allowable deviation is 0.1 mm with SRs of 2.9%. With these results, HM-FPP craftsmen must be more careful in making the size of the probe hole.

Abstract

The COVID-19 pandemic has forced us to transform traditional learning methods into online or distance learning. This shift has affected not only students but also teachers and parents. Face-to-face learning was replaced by the use of platforms such as Google Classroom, WhatsApp groups, and others. Students, who previously interacted directly with teachers, had to adapt to learning through Google Classroom or WhatsApp groups. This transition required students to develop their own learning patterns and self-regulated learning (SRL). By combining simple online learning via WhatsApp groups or Google Classroom with more interactive learning methods, students' SRL can be enhanced. Observations from teachers and responses from students indicate that blended learning has a positive impact on SRL among vocational high school students.

Abstract

This study explores the influence of numerical literacy, verbal ability, learning motivation in science, and self-regulation on academic achievement among high school students. In today's dynamic educational landscape, success requires more than academic knowledge—it also demands motivation and self-directed learning strategies. This research aimed to examine how these four factors interrelate to predict learning outcomes. Employing an ex-post facto quantitative design, data were collected from 119 high school students across four schools using validated questionnaires and learning outcome assessments. The variables included numerical literacy, verbal ability, and science learning motivation as independent variables, self-regulation as a mediating variable, and academic achievement as the dependent variable. The data were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM). The results showed that all three independent variables significantly and positively affected self-regulation: numerical literacy (β = 0.410, p < 0.001), verbal ability (β = 0.291, p < 0.01), and science learning motivation (β = 0.215, p < 0.05). Furthermore, self-regulation positively influenced academic achievement (β = 0.405, p < 0.001). These findings underscore the critical role of self-regulation as a bridge between cognitive skills and academic performance. By strengthening students’ ability to manage their own learning, educators can enhance academic success, especially in numeracy and science-based learning environments.

Abstract

The Cu/Ni layer is a layer that can be used as a material for low temperature sensors. The coating can be made by means of electroplating. Electroplating has limitations in controlling the number and size of metal particles. Therefore, the purpose of this study was to determine the grain size of Cu and Ni in electroplated Cu/Ni layers at varying voltages from 6 to 8 volts using the modified Scherrer method and to analyze the effect of stress on grain size. The method used in this research is descriptive method using a quantitative approach. The results showed that the grain size of the Cu substrate was D= (0.5071 ± 0.06) nm. As for the Ni layer, stress affects grain size. A voltage of 7 volts can produce the largest grain size of 0.776059 nm.

Abstract

Coating of Cu/Ni with nitrocellulose (NC) has been carried out with the aim of determining the effect of using NC as a protective film on the sensitivity and activation energy of the sensor. The samples used were Cu/Ni and Cu/Ni/Cu where the NC coating on Cu/Ni was carried out using a spray method with a pressure of 1.2 Mpa. Both sensor samples were used to measure the temperature of liquid nitrogen (liquid N2) which was varied from -160C - 0C. In addition to temperature, voltage and current were also measured. The sensitivity value was obtained from the slope of the resistance curve against temperature, while the activation energy was obtained from the slope of the logarithm of conductivity against one per absolute temperature. From the sensitivity test, it is known that both sensors have a tendency to be more sensitive when the temperature is lowered, but the presence of the NC layer causes a decrease in sensitivity of up to 18.9%, namely from 3.95 /C to 3.18 /C at a temperature of -160C following the equation S(T)=0.10e-0.012T. The use of NC protective layer can also increase the activation energy by 1.3%, namely from (4.29  0.01)x10-9 eV to (4.35  0.01)x10-9 eV. These results can be used as a consideration for temperature sensor manufacturers that the use of NC protective layer is important but can reduce sensor sensitivity.

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

Penelitian ini bertujuan untuk menentukan kepekaan sensor sebagai sensor gas dari substrat Cu yang dilapisi SnO2 melalui proses elektroplating dengan variasi suhu larutan elektrolit dan oksidasi termal. Parameter deposisi ditetapkan yaitu larutan elektrolit dengan melarutkan SnCl2 pada aquades, tegangan 4,5 V, jarak elektroda 3 cm, dan waktu elektroplating selama 3 menit. Pada uji kepekaan sensor dilakukan dengan mengamati proses pembusukan makanan dengan meletakkan makanan yang diamati dan sensor pada kontiner uji. Akuisisi data suhu, kelembapan, kadar CO2, dan hambatan sensor dilakukan dengan bantuan transduser dan software Logger Pro. Berdasarkan hasil penelitian, sampel sensor dengan suhu elektrolit 600C (sampel B) pada proses elektroplating menunjukkan hasil yang lebih baik dari sampel sensor dengan suhu elektrolit 300C (sampel A).  Sampel B mampu membaca perubahan suhu lebih baik dengan nilai koefisien determinasi R2 = 0,66943. Sampel B juga mampu membaca perubahan kadar CO2 dengan lebih baik dengan R2 = 0,98225. Hal ini dikarenakan proses elektroplating yang lebih efektif dilihat dari perubahan massa dan tebal lapisan SnO2. Kepekaan sampel B dengan nilai kepekaan S([CO2]) = 9.42E-5 - 1.17E-9[CO2] lebih baik daripada sampel A dengan nilai kepekaan S([CO2]) = -2.34E-4 + 4.25E-9[CO2] ditunjukkan oleh grafik. Sampel B menunjukkan kurva linier negatif dengan kemiringan yang landai. Kondisi tersebut menunjukkan sensor gas yang stabil.
