Cognitive Improvement in Thermodynamic Functions With Calculus Chain Rule

Sumihar Simangunsong — 2024-02-17

This research was motivated by the low ability of students to apply mathematical solution methods to thermodynamic functions. Thermodynamic functions are functions that consist of pressure, temperature, volume and enthalpy functions where changes in one function can occur due to changes in other functions. The aim of this research was to show the implementation of chain rules in thermodynamic function problems by relying on a process technique to improve students' cognitive awareness of thermodynamic functions. The place of this research was at the TD Pardede Institute of Science and Technology. The process of understanding chain rules is very impactful for understanding thermodynamic state functions. Differential decomposition of functions within functions is also described in the chain rule method. Thermodynamic functions which consist of pressure, temperature, volume and enthalpy functions can depend on each other so that the chain rule analysis method can be clearly used. With this method students will also be given the opportunity to connect one concept with other thermodynamic concepts. Apart from that, this method can be used anywhere. This shows a cognitive increase in terms of cognitive elements, cognitive structure and cognitive function.

Climate Diplomacy: Efforts to save the earth from the climate crisis?

Adi Subiyanto — 2024-02-01

Various human activities have caused the concentration of greenhouse gases (GHG) such as CO₂, CH₄, and N₂O in the earth's atmosphere to increase, which has an impact on increasing global temperatures and has led to the climate crisis. To reduce GHG emissions, countries that ratified the Paris Agreement set targets to be achieved as Nationally Determined Contributions (NDC). The Paris Agreement must be integrated into diplomatic practice as climate diplomacy. The method used in this research is qualitative-descriptive analysis. The data used were reports from the Intergovernmental Panel on Climate Change (IPCC) and Indonesia's contribution to the NDC document. The research results showed that 1) Global warming had caused a climate crisis so that it has become a threat to the survival of life; 2) Indonesia's contribution in reducing the rate of global warming through NDC had not been able to reach the target of 29% with its own efforts or 41% with assistance and cooperation; and 3) Climate diplomacy, which is expected as an effort to reduce the climate crisis, was not easy to carry out. The obstacle to implementing climate diplomacy is that each country has its own interests.

Deka Hermiati — 2024-02-01

This research aimed to provide a general overview of students' learning motivation in science at the junior high school level and to compare the level of learning motivation among students from three different schools: SMPN 27 Kerinci, MTsN 1 Sungai Penuh, and MTsS Siulak in the 2023/2024 Academic Year. The sample for this research consisted of 72 students, with 24 students from each school. The research utilized descriptive and comparative methods. Data on students' learning motivation were collected through the Students' Adaptive Learning Engagement in Science Questionnaire and analyzed descriptively and comparatively using the Kruskal-Wallis test. The results indicate that, overall, students exhibit high motivation to learn science, scoring 4.10 on a scale of 5.00. Additionally, students from the three different schools also demonstrated high average learning motivation, with scores of 4.26 (SMP N 27 Kerinci), 4.15 (MTsS Siulak), and 4.01 (MTsN 1 Sungai Penuh). Despite these differences, the Kruskal-Wallis statistical test revealed that the variations were not statistically significant (ρ=0.09). Furthermore, when examining each indicator separately, only one indicator, namely self-regulation (ρ=0.008), showed a significant difference. This distinction in self-regulation was influenced by students' perceptions regarding tasks in science learning, including their views on effort, persistence, punctuality, and a lack of discrimination regarding the form of tasks to be completed.
