Abstract

This research aims to investigate and compare students’ responses in solving physics problems about kinematics concepts. The students’ responses cover the conceptual understanding as overall performance, representational abilities, and students’ response patterns.This research is a non-experimental survey research with thequantitative-descriptive approach. The research samples consisted of 56 students determined by the purposive sampling technique. The research instrument was adapted from the Force Concept Inventory (FCI) in Physport Assessmentwhich has been validated. The students’ responses were analyzedusing descriptive statistics to measure the average and standard deviation. Students’ answers were also grouped according to the type of representation and pattern of presentation in percentages. The results showed a significant difference between the tenth-grade students’ and eleventh-grade students' understanding of the Kinematics concept. Furthermore, the students found it easier to answer mathematical representation questions rather than graphical representation questions.

Abstract

Experiments have been carried out on determining the value of the moment of inertia of a hollow cylinder. This study aims to analyze the value of the moment of inertia with variations in the radius of the hollow cylinder using the Phyphox Application (Physical Phone Experiment). This research is experimental. The tools and material used area 1-meter longboard, three hollow cylinders with different radius sizes but the same mass, smartphone, laptop, caliper, and balance.The experiment of rolling motion on a hollow cylinder on an inclined plane is assisted by data processing in a Phyphoxapplication. From the experiment, the result of the moment of inertia value from data processing is 4.89 x 10-4kg.m2, 9.82 x 10-4kg.m2, 12.4 x10-4kg.m2. This research can be used as a teacher reference in teaching the topic of moments of inertia in physics learning at school. This is highly recommended for distance learning during the pandemic so that mastery of concepts is maximized. Further research is suggested that it can be tried to use other materials with other types of rigid bodies to find the moment of inertia. Further references on digital application media to assist learning are also needed considering the dynamic development of technology.

Abstract

This research investigates the transformation of the seventh-grade students' mental representations of the rectilinear propagation of light. The researcher employed the quasi-experimental method on two groups of students aged 12-13 years. The survey involved 102 students who were divided into two equal groups determined by the stratified sampling technique. The first group participated in a didactic intervention based on the students' representations. The second group of students participated in a traditional school teaching. The Mann–Whitney U test was utilized for calculating the significance of the data. The statistical analysis showed that the pretest and the posttest progress was statistically significant for the first group. It resulted in the mental constitution of a representation that is compatible with the scientific model.The research results allow the design of effective interventions for the teaching of light propagation and geometric optics in general.

Abstract

Research has been conducted using the gravity method in the Wai Selabung area, South Ogan Kemiring Ulu Regency, South Sumatra Province, correlated with geological data, magnetotellurics, and geochemical data. This research aims to get structural patterns, subsurface models and identify the heat source and reservoir areas of the Wai Selabung geothermal system. This study uses the gravity method to model the subsurface, which is correlated with magnetotelluric and geochemical data to identify reservoir prospect areas. The results obtained from this research include residual anomalies in the research area showing the presence of a northwest-southeast trending fault structure by the main fault structure of this area trending northwest-southeast and slightly southwest-northeast. Analysis of the Second Vertical Derivative value of zero indicates the boundaries of the geothermal reservoir in the middle of the research area.  The results of the 3D inversion modeling of the research area show that low density (2 to 2.15 g/cm3) indicates the location of the reservoir, medium-density values (2.2 to 2.4 g/cm3) are tertiary sandstone sedimentary. The high-density distribution value (2.5 to 2.9 g/cm3) indicates a potential heat source. And based on the analysis of the gravity method correlated with geological data, magnetotelluric, and geochemical data, the prospect area for the Wai Selabung geothermal reservoir, is around Teluk Agung, Perekan, and Talang Tebat.

Abstract

In this study, the researchers measured cicadas' sound waves, considering that cicadas are mostly found in rural areas. The intensity level meter (AMTAST AMF003) was used with time variations (9:00 JST; 12:00 JST; and 15:00 JST). Measurements of air temperature differences (Krisbow Temperature & Humidity Data Logger) were also carried out, and weather conditions were also considered in data collection using satellite data from Himawari, Japan. The interpretation results of intensity level's trend measured at 3:00 pm JST were decreased concerning the changes in days. Meanwhile, the measurement at 09:00 am and 12:00 pm JST did not show a decrement concerning the changes in days (31 days in total). These results show that temperature changes (towards autumn) can affect the intensity level of sound waves. In addition, slightly different intensity levels can affect large changes in acoustic power or the produced sound.

Abstract

Several studies have reported that exposure to ELF magnetic fields can increase cell death and inhibit bacterial proliferation. This study aimed to analyze the resistance of soy milk exposed to ELF magnetic fields with 300 μT and 500 μT intensities. The researchers employed a completely randomized design. The soy milk samples were exposed to ELF magnetic fields intensities of 300 μT and 500 μT for 60, 90, and 120 minutes. The variables studied were physical resistance (aroma, color, texture, and clot formation), pH, and density. The physical condition data were analyzed descriptively, while the pH and density data were analyzed using Mann Whitney and Kruskal Wallis statistics. The results showed that the aroma, texture, and clot formation on the surface of the samples exposed to the 500 μT intensity were better than the control group until ten hours after exposure. However, the color was not different from the control group. Therefore, exposure to ELF magnetic fields intensity of 500 μT potentially increased the soy milk resistance. The research results can be used as the basis for developing food security technology with ELFelectromagnetic wave radiation.

Abstract

Based on the amount of discharge or current, the river flows in Central Kalimantan have the potential to produce electrical energy. The purposes of this study were to design an undershot type of floating waterwheel and to test the effective bending angle at the radius of the grasshopper elbow in producing the most optimum power. This research uses experimental methods. The tools used are: mobile phone, multimeter, the gate of light, timer counter, flow rate, and the dimensions of the waterwheel diameter is 6 meters. Grasshopper angles vary from 0°, 30°, 45°, 60o, and 90° with a submerged blade depth of 0.24 m. The results showed that the undershot waterwheel with a flexible pinwheel (like a grasshopper's elbow) produced a faster and more effective rotation than a wheel with a fixed pinwheel and blades. Because the waterwheel has a flexible pinwheel and the butterfly blades experience little resistance when moving in water, the wheel generates more electrical energy than a wheel with fixed pinwheels and blades.At the angle of bending of the radius of the grasshopper blade 30º with the butterfly blade, it produces more optimal electrical energy than angles 0°, 45°, 60o, and 90°. Suggestions for further research are to test the waterwheel in weak and medium current rivers
