Lighting in the bedroom is important in maintaining the quality of children's sleep. At the age of 0-5 years, a child has a sleep duration of around 11-18 hours, so it is necessary to pay attention to the lighting in the bedroom so that children have quality sleep time. This study aims to determine the effect of lighting in the bedroom on the sleep quality of children aged 0-5 years. Samples were taken randomly with the age range of children 0-5 years with the criteria of children accustomed to sleeping with the lights off as many as 6 samples. The number of samples was adjusted to the availability of samples around the research site in Tinjomoyo village. Data collection techniques were observation and questionnaires. The parents of the sample filled out the observation sheets and questionnaires. The duration of data collection depends on how many times each sample wakes up during sleep at night, starting when the child falls asleep until 03.00 AM. The results showed that there was an effect of bedroom lighting on the sleep quality of children aged 0-5 years as indicated by a change in the child's total awakening, which is an average of 2 fewer awakenings during sleep from the lights on to the lights off.

The atmosphere is rich in positive ions, rendering it electrically more positive than the Earth's surface. This characteristic presents the atmosphere as a potential source of renewable energy through ion harvesting. This study harnesses the electrical properties by optimizing ion harvesting electrodes using pristine graphene and graphene-Au thin films to generate clean electricity. Research methods included Raman Spectroscopy and Cyclic Voltammetry (CV) to assess the surface characteristics and capacitance of the graphene samples, along with laboratory-scale ion harvesting simulations to evaluate the energy data produced in the ion harvesting process. The samples used in this study were identified as bilayer graphene, as confirmed by Raman Spectroscopy. CV testing yielded capacitance values of 0.40288 F for pristine graphene and 0.44879 F for graphene-Au samples. According to ion harvesting simulations, graphene-Au generated approximately 6.8 times more energy than pristine graphene and five times more energy than copper alone. The respective energy outputs for graphene-Au, pristine graphene, and pure copper were 1.376 mW, 1.157 mW, and 0.374 mW. These results demonstrate that adding a graphene layer to the atmospheric ion-harvesting electrode can optimize the electricity generation process.

Entering the digital era, the culture of human life is increasingly inseparable from the use of electromagnetic waves which are very useful in supporting human life, but in the other side, it also has negative impacts in the form of radiation that threatens human health. Only few people realize that ornamental plants have many benefits other than as a decoration inside or outside the room. Several types of ornamental plants have the ability to absorb electromagnetic radiation emitted by electronic equipment. In this simple physics research, measurements were made to compare the absorption of several types of ornamental plants to electromagnetic wave radiation, those are karet kebo, betel, succulent, ivy plant, and snake plant. The research results show that snake plant’s ability to absorb electromagnetic wave radiation is the greatest than others. Research conducted on ivy shows that the absorption of ornamental plants to electromagnetic wave radiation is influenced by the distance of the plant to the radiation source, where the closer the distance between the ornamental plants to the source of electromagnetic wave radiation is, the greater the absorption of radiation occurs, resulting in a decrease in the intensity of electromagnetic radiation also getting bigger. The trend of changes in the absorption of electromagnetic wave radiation shows a decrease in each increase in distance according to the exponential graph.

A coupled spring-pendulum system in a conservative field was studied where the equation of motion of the system using Lagrangian and Hamiltonian equation were obtained. The equation of motion represented by a second-order differential equation from the three generalized coordinate were used. The potential energy equal to zero when the system is in its equilibrium position. The generalized coordinate that being used were the angle of the first pendulum θ_1, the angle of the second pendulum θ_2, and the increase in the length of the spring x. The resulting equation of motion can be used to determine the dynamics behavior of the system at any time. Students' understanding is expected to be more complete by providing a procedure to derive the Lagrangian equation of motion.

The concept inventory instrument is one of the test tools presented online which is used to measure students' conceptual understanding. The research model used is Borg and Gall. The instrument developed were validated by expert judgment. The results of the validation assessment are in the form of qualitative and quantitative content validity. The results of qualitative validity can be seen in terms of materials obtained on an average of 99.2%, construction is averaged 93.3%, and language is averaged 97.4%. While the quantitative analysis of validity is done using Aiken's v equations obtained an average of 0.841 of valored 0.841 is so high, it is worth being used to measure understanding the conception of learners.
