Abstract

Oscillatory motions are an essential part of our physical world. These motions need to be studied and learned by students. However, complicated oscillatory motions, e.g.: spring coupled pendulum, are rarely taught to students because their analytical solutions (if they exist) are complicated Here, we use the Tracker software to bridge between the actual coupled pendulum oscillation and its analytical solution. This study aimed to determine the period and frequency of Tracker software-assisted spring coupled pendulum oscillations. The displacement of the pendulum is divided into in-phase and out-of-phase motions. Data collection was carried out by recording the oscillatory motions up to 10 oscillations. The data were obtained from the pendulum position with respect to time. The data analysis techniques in this study used two methods, namely: i) Tracker software and ii) analytical calculations. The results showed that the period and frequency obtained via the Tracker software were in accordance with the analytical calculations. The periods of the in-phase motion and analytical calculation were 1.42 s and 1.54 s, respectively. The periods of the out-of-phase motions and analytical calculation were 0.7 s and 0.55 s, respectively. The frequencies of the in-phase motion and analytical calculation were 0.70 Hz and 0.65 Hz, respectively. The frequencies of the out-of-phase motions and analytical calculation were 1.50 Hz and 1.83 Hz, respectively. The uncertainty values of the results were 7% to 22%. Hence, the spring coupled pendulum oscillations became tractable and can be compared to the analytical solution.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh lingkungan kerja dan efikasi diri terhadap kinerja pegawai pada Kantor Dinas Pendidikan Deli Serdang. Teknik pengambilan sampel menggunakan sampel jenuh berjumlah 76 orang. Metode pengumpulan data menggunakan kuesioner. Dari persamaan regresi Y = 5,550 + 0,452X1 + 0,715X2 + e. Pada uji hipotesis parsial (Uji t) variabel lingkungan kerja berpengaruh positif dan signifikan terhadap kinerja pegawai dengan nilai t hitung > t tabel (6,536 > 1,665) dan nilai signifikan 0,000 < 0,05 dan efikasi diri berpengaruh positif dan signifikan terhadap kinerja pegawai dengan nilai t hitung > t tabel (8,190 > 1,665) dan nilai signifikan 0,000 < 0,05. Hasil uji hipotesis secara simultan (Uji F) variabel lingkungan kerja dan efikasi diri berpengaruh positif dan signifikan terhadap kinerja pegawai dengan nilai F hitung > F tabel (74,620 > 3,12) dan nilai signifikan 0,000 < 0,05. Hasil uji determinasi diperoleh nilai R Square sebesar 0,672, artinya variabel kinerja pegawai dapat dijelaskan sebesar 67,2% oleh lingkungan kerja dan efikasi diri, sementara sisanya 32,8% dijelaskan oleh variabel lain yang tidak dimasukkan dalam penelitian ini.

Abstract

Indonesia is a tropical archipelago located along the equator, where air temperature patterns exhibit seasonal trends and unstable fluctuations. This instability can impact several sectors, including agriculture—making it difficult for farmers to determine planting and harvesting times—electricity demand, which increases during hotter periods, and public health, as erratic weather may reduce productivity and elevate the risk of diseases such as dehydration, asthma, and respiratory infections. This study aims to evaluate the performance of the Trigonometric, Box-Cox Transformation, ARMA Errors, Trend, and Seasonal (TBATS) model and the Seasonal Autoregressive Integrated Moving Average (SARIMA) model in forecasting air temperature in Indonesia. The dataset used comprises 2-meter air temperature records in Indonesia from January 1940 to August 2024, obtained from ECMWF. The evaluation method applied is cross-validation with a rolling basis. The results show that the RMSE for the TBATS model is 21.3843%, while the SARIMA model has an RMSE of 21.2958%. These results indicate that SARIMA has a slightly better performance than TBATS. However, both methods perform well in forecasting air temperature in Indonesia, as their RMSE percentages are within an acceptable range. This research is expected to contribute to the scientific literature on air temperature forecasting in Indonesia and encourage further studies on hybrid models that integrate TBATS and SARIMA. Additionally, it may support efforts to mitigate the adverse impacts of air temperature changes in the country.

Abstract

This research aimed to improve students' graphical representation using the guided inquiry learning model assisted by the Tracker software. The method used in this research was a pre-experimental study with a one-group pretest-posttest design. The data collection techniques used were observation, interview, and tests. The sample for this research was students of science class X at Public Senior High School. The analysis techniques were carried out using Wilcoxon and N-Gain test calculations. The results of the research showed that the Wilcoxon test produced a significance, which means that there were differences in the guided inquiry learning model assisted by Tracker software to improve the graphical representation abilities of high school students on the Work and Energy topic. The N-Gain test indicated that more than half of the students achieved a high category, while only a small number obtained the low category. Moreover, the N-Gain results for the two-question item indicators showed that most students were in the medium and high categories. Thus, students' graphical representation abilities can be improved using the guided inquiry learning model assisted by the Tracker software.

Abstract

Integrating Socio Scientific Issues (SSI) in physics learning encourage students to actively discuss a problem, understand the nature of science, consider the controversies and their influence on the world both physically and socially. This research aims to produce an e-book on Static Fluid topic based on SSI assisted by Heyzine Flipbook, which is suitable for use to improve students' critical thinking and collaboration skills and determining its effectiveness. This method used in this study is research and development (R&D) with the define, design, develop, and disseminate (4D) model. The define stage aims to determine what is needed in the e-book development. The design stage is designing the e-book based on a certain format. The develop stage involves making the products, namely the e-book and instruments. The disseminate stage involves widespread distribution of the e-book that has been developed. The research result shows that the e-book based on SSI assisted by Heyzine Flipbook is valid based on the evaluation of physics experts and teachers, as well stated valid with very good category by the students’ responses. The e-book helps students to increase their abilities to think critically and collaborate in the classroom.
