Abstract

The climatological pattern of rainfall and the occurrence of extreme drought and extreme wet in Indonesia are influenced by monsoon dynamics, topography, and Sea Surface Temperature Anomalies (SSTA) in the Pacific and Indian Oceans. Although studies on extreme droughts in Indonesia exist, none have quantified the spatial frequency of extreme drought and rainfall events. This study aims to determine the frequency and trend of extreme drought and extreme rain in Indonesia during 1995–2024. Gridded precipitation data from the Global Precipitation Climatology Center (GPCC) with 0.5° resolution were used. Frequencies of extreme drought and extreme wet were calculated using the Standardized Precipitation Index (SPI), while trends were estimated from the Poisson Regression slope. Frequency and trend were computed for the grid to represent spatial distributions. SPI results at 3, 6, and 12-month scales show Sumatra, Kalimantan, and Papua experienced extreme droughts 8–12 times, with varying frequencies. Extreme droughts were widespread in eastern Indonesia during the dry season (JJA and SON), with longer persistence in SPI-6 and SPI-12. In contrast, extreme wet events occurred more frequently in western and central Indonesia, during the rainy season (DJF), when the western monsoon transported moisture from the Indian Ocean.

Abstract

This study aims to develop a critical thinking skills test instrument on the Coulomb's Law material that meets the qualifications including aspects of feasibility validation, validity and reliability. This study is a development research with the ADDIE approach. This study was conducted at SMA Negeri 1 Payaraman with a sample of 30 students in class XII.3. The results showed that the test instrument was declared feasible based on the feasibility validation test, valid based on the validity test and reliable based on the reliability test. The average feasibility validation score was 3.66, with a feasible category. The validity test stated that the r count of all test instruments > r table (0.361) and the reliability value was 0.733.

Abstract

Purpose of the study: This research aims to develop learning media using computer-based collision material in the context of the traditional game of marbles. Methodology: This research is a Research and Development study using the ADDIE research design. The research was conducted at MA Al-Fatah Palembang using instruments in the form of interviews and questionnaires for data collection. Interviews were conducted with physics subject teachers at MA Al-Fatah Palembang. The questionnaire was given to media expert validators, material expert validators, teachers and students to see the validity and practicality of media use. Main Findings: The result of this research is a learning media product using computer-based collision material in the context of the traditional game of marbles which meets the valid and practical criteria. The results of media expert validation that have been carried out show percentages of 91,7% with very valid categories. The material expert validation results show a percentage of 92.8% with a very valid category. The results of the limited trial showed that the percentage of assessments from physics subject teachers was 89,2% in the very practical category and students' responses to the use of learning media showed a percentage of 87.3% in the very practical category. Novelty/Originality of this study: The main novelty of this study lies in utilizing a traditional game as a contextual and engaging framework to teach abstract physics concepts, such as collisions, in a more comprehensible way.
