Abstract

This  research was conducted in North Sumatra, namely at Iskandar Muda, Malikussaleh and Deli Serdang stations in the period 1885 to 2019. The purpose of the study was to analyze seasonal and interannual rainfall patterns. The method used is Fast Fourier Transform (FFT) and correlation between rainfall, sea surface temperature and wind. The results of the study showed that the rainfall pattern at Iskandar Muda, Malikussaleh and Deli Serdang stations had two peaks of rainfall. The peak rainfall of the three stations occurs in May and the second peak has differences between Deli Serdang and Iskandar Muda and Malikussaleh stations. Where the peaks of high periodization are only in the 6-month and 12-month periods. There is also a peak periodogram from each station seen in 18-30 months. Rainfall periodogram analysis shows the magnitude of data frequency for each phase cycle and its frequency. The correlation between rainfall, wind and sea surface temperature (SST) at the three stations has a different pattern. At Deli Serdang station, there is an influence of ENSO and IOD, while at Iskandar Muda and Malikussaleh stations there is no influence of ENSO and IOD. Then in the September, October, November (SON) season at the three stations there is no visible influence of ENSO and IOD.

Abstract

This study aims to analyze the trend of extreme temperatures in Kalimantan over the past few decades. The data used are daily temperatures from meteorological stations in West Kalimantan, Central Kalimantan, and South Kalimantan, with an observation period of January 1985 to December 2022. The research methodology involves four main stages: data collection, extreme temperature index calculation, trend detection, and correlation analysis with ENSO and IOD. The results showed an increasing trend in extreme temperatures (warming). The increase in mean annual maximum temperature (TXmean) ranged from 0.03°C to 2°C per century, while the mean annual minimum temperature increased from 0.2°C to 0.5°C per century. Monthly maximum value of daily max temperature (TXx) the increasing trend ranged from 0.19°C to 1.7°C, monthly maximum value of daily min temperature (TNx) increased from 0.1°C to 0.5°C. The monthly mean difference between daily max and min temperature (DTR) also shows an increase of 0.5°C to 1.7°C. This trend indicates that daytime (TXmean, TXx) and nighttime (TNmean, TNx) conditions in Kalimantan, especially in West, Central, and South Kalimantan, are getting hotter, with the daytime experiencing a more significant increase in temperature. The correlation between the extreme temperature index and ENSO and IOD is negative and positive, indicating that ENSO and IOD do not fully influence the increase in extreme temperatures. These findings have important implications for disaster mitigation planning and adaptation to climate change in the Kalimantan region.

Abstract

The rapid advancement of digital technologies has fundamentally transformed educational practices, particularly in Islamic Religious Education (PAI), where technology integration must balance pedagogical innovation with moral and spiritual values. This study explores digital transformation in PAI learning by reviewing and synthesizing relevant scholarly literature published between 2020 and 2025. Drawing on peer-reviewed journal articles, conference proceedings, and academic publications sourced from Google Scholar and nationally accredited journals, the review focuses on themes of digital pedagogy, teacher competence, ethical considerations, and the application of the TPACK framework in value-based education. The synthesis highlights three key dimensions: (1) opportunities, where technology enhances learning accessibility, student engagement, and instructional personalization through interactive media and digital platforms; (2) challenges, including infrastructural limitations, varying levels of teacher digital competence, and ethical concerns regarding content authenticity and data privacy in religious contexts; and (3) strategic solutions, emphasizing continuous TPACK-based professional development, the creation of religiously aligned digital content, and supportive institutional policies. This review contributes a conceptual understanding of how digital transformation can be sustainably integrated into PAI, underscoring that successful implementation requires holistic alignment of technology, pedagogical competence, ethical governance, and systemic support. The findings offer practical recommendations for educators
