Abstract

The thermoacoustic refrigerator is an innovative alternative and did not use substances that had a negative impact on the environment such as freon, but using air as the working substance. The materials used the refrigerator were easily obtained and the construction components were simple so that made this refrigerator was cheap, easy to make and easy to maintain. Stack was used in the thermoacoustic refrigerator system used PVC (Polyvinyl chloride) which is parallel cylindrical shape and diameter (1.50 ± 0.05) mm and length of 8 cm. Variations of loudspeaker input power that used were 20 watt, 30 watt, 40 watt, 50 watt and 60 watt. Variations of the input power that used to determine the effect of loudspeaker input power to decreasing temperature in the operating of the thermoacoustic refrigerator system using  PVC stack. From the result, loudspeaker input power influenced on the decreasing temperature that was 6.0 °C for 20 watts, 6.7 °C for 30 watts, 7.2 °C for 40 watts, 8.0 °C for 50 watts and 9.0 °C for 60 watts. From these results indicated optimum decreasing temperature depended on the amount of loudspeaker power that was directly proportional to the decreasing temperature obtained.

Abstract

Hamiltonian a known system in many matters does not guarantee that the equation can be resolved, e.g. due to minor disturbances such as electric fields or magnetic fields that can lead to slight changes in energy and its particle functions, for such issues it should be used disorder theory (perturbation theory). The perturbation theory can determine how much the result of the presence of disruption to energy levels and Eigen's functions. The energy possessed by particles in addition to being influenced by quantum numbers (nx, ny and nz) and the size of the potential box are also influenced by interference in the form of magnetic energy produced due to the motion of particles (electrons) in the core intrinsic magnetic field (proton) which affects the energy value does not appear due to the value of this magnetic energy disorder is very small, while for interference that is an extrinsic magnetic energy has shown a 10 (Tesla). The wider the size of the box then the energy that the particles have is smaller so that the energy level and the particle energy spectrum in the potential box will appear continuous. It can be concluded that the particle energy level relies on the length of the potential box, the quantum number of particles, and also the interference that particles have.

Abstract

Research on environmentally friendly thermo-acoustic coolants uses a heat exchanger from the cable sheath material. The resonator tube used in the thermoelectric cooler is a 5.25 cm diameter PVC (polyvinyl chloride) tube with a length of 87 cm. Variations in stack lengths of 4cm, 5cm, 6cm, 7cm, and 8cm were performed to obtain results on thermoelectric coolers. Results are available on the use of stack length 4 cm high temperature 21.6 oC from the initial temperature), the stack length 5 cm high temperature 21.1 oC from the initial temperature (room temperature), the stack length of 6 cm resulted in a maximum temperature drop of 22.6 oC from the initial temperature (room temperature), the stack length of 7 cm resulted in a maximum temperature drop of 22.0 oC from the initial temperature (room temperature), while the stack length of 8 cm resulted in a decrease in temperature maximum of 23.3 oC from the initial temperature (room temperature). Keywords: Thermoacoustic, stack, temperature changes.

Abstract

The issue of science knowledge comprehension among early childhood children is a complex matter that requires serious attention in many countries, including Indonesia. Several studies indicate that the understanding of science knowledge among early childhood children in Indonesia is still relatively low. One of the efforts to provide a solution to these issues is the development of electronic book (e-book) instructional media. This development research employs the ADDIE model. The ADDIE model's developmental stages include analysis, design, development, implementation, and evaluation. The target audience is Kindergarten Group B children aged 5-6 years from TK Lab.School IKIP PGRI Jember. The instruments used for this research are expert media review, expert design review, expert content review, responses from small and large focus groups. Based on the response results, the understanding of participants reached 90,6%, the appeal was rated at 90,4%, with an overall average of 90,5%. The e-book's development results, based on the participants' responses, indicate that the usage of the e-book is highly suitable and effective in enhancing the understanding of science among children aged 5-6 years.

Abstract

This study investigates the effectiveness of Android-based Augmented Reality (AR) in enhancing students' learning motivation in science. Using a quasi-experimental design, two groups were involved: a control group, which was taught using conventional methods, and an experimental group, which used AR media. The research sample consisted of 42 high school students, divided into two groups of 21 each. Data were collected through pretests and posttests, as well as a motivation questionnaire adapted from the ARCS model (Attention, Relevance, Confidence, Satisfaction). The results revealed a significant difference in motivation between the two groups, with the experimental group showing an average posttest score of 84.11, compared to 61.72 in the control group. The t-test showed a significant difference (p = 0.001), and N-gain analysis demonstrated that the experimental group had a higher N-gain (77.59%) compared to the control group (56.56%), indicating the effectiveness of AR. Additionally, the experimental group showed significant improvements in attention and satisfaction. This study concludes that Android-based AR is an effective tool for increasing student motivation in science, and recommends further research on its use in other subjects with larger samples.

Abstract

This study aims to enhance the self-confidence of early childhood students through the implementation of role-playing methods at RA Miftahul Hidayah, Panti District, Jember Regency. The research method used is Classroom Action Research (CAR), conducted in two cycles, each consisting of planning, implementation, observation, and reflection phases. The research subjects were 20 children aged 4-5 years. Results in Cycle I indicated that 55% of the children showed increased self-confidence, but this result did not meet the target of 75% success. In Cycle II, improvements were made through individualized guidance and more varied role-playing scenarios. As a result, 75% of the children showed significant self-confidence enhancement. Thus, role-playing methods have proven effective in supporting the socio-emotional development of children and can be widely implemented in early childhood education settings.
