Abstract

Perubahan tata guna lahan dapat memberikan manfaat, namun dapat juga berakibat buruk bagi lingkungan, seperti pembakaran dan penebangan terhadap vegetasi/hutan di lahan gambut, hal ini menyebabkan air di lahan gambut berkurang secara berlebihan sehingga menyebabkan lahan gambut menjadi kering dan mudah terbakar. Perhitungan neraca air lahan gambut sangat penting dilakukan untuk mengetahui kondisi distribusi air. Penelitian ini bertujuan untuk mengetahui kondisi neraca air dan pengaruh perubahan tata guna lahan terhadap kondisi neraca air pada KHG Pulau Tebing Tinggi berdasarkan tata guna lahan tahun 2010 dan 2019. Pemodelan hidrologi dilakukan menggunakan model TMWB (Thornthwaite Mather Water Balance berdasarkan data curah hujan, klimatologi, tata guna lahan dan tekstur tanah. Hasil analisis tata guna lahan tahun 2010 dan 2019 terdapat perubahan luasan hutan menjadi lahan pertanian dan perkebunan. Perubahan tata guna lahan menjadi lahan pertanian dan perkebunan dapat menyebabkan air hujan yang seharusnya meresap ke dalam tanah, berubah menjadi limpasan aliran permukaan yang umumnya mengalir ke sungai/kanal, sehingga dapat mempengaruhi keseimbangan air dan lingkungan disekitarnya. Hasil perhitungan neraca air tiap Sub KHG Pulau Tebing Tinggi periode tahun 2010 dan 2019, menunjukkan bahwa tahun 2019 kondisi limpasan air (runoff) lebih besar dibandingkan tahun 2010, sehingga ada kecenderungan disebabkan oleh perubahan tata guna lahan.

Abstract

This study presents a bibliometric analysis of the scientific literature on "Teacher Readiness in Response to Educational Transformation," using the Scopus database to examine trends, collaborations, and key research themes. The analysis reveals a significant increase in publications since 2018, with a notable peak in 2021, likely due to the impact of the COVID-19 pandemic on education systems worldwide. Central themes include teacher readiness for integrating digital technologies, STEM education, and the challenges of online teaching. The keyword co-occurrence network highlights the close connections between teacher readiness and topics such as ICT, professional development, and early childhood education. Additionally, the country collaboration network shows strong contributions from the United States, Australia, China, and Hong Kong, although global cooperation remains limited. The study also identifies the most active journals, with the Australian Journal of Teacher Education and Journal of Research on Technology in Education being prominent platforms. The findings underscore the growing need for research on teacher preparedness to address the challenges of an evolving educational landscape. Future research should focus on emerging technologies like AI and VR in education, while expanding cross-country studies to ensure a more inclusive understanding of teacher readiness across diverse contexts.

Abstract

Fishermen in the waters of Sadai Village mostly use the Bagan tancap by catching using different colors of lights. The study aimed to determine the effect of light colors (white, red, yellow, green, and blue) on the Bagan tancap fishing gear on catches in the waters of Sadai Village, South Bangka Regency. This research was conducted on April 28 - May 28 2022 in the waters of Sadai Village, South Bangka Regency. The method used is an experimental method using a randomized block design (RBD) and Duncan's further test. The data collected includes the type of catch, the total weight of the catch, the number of catches, and environmental parameters. The results showed that the treatment of different light colors affected the number (fish) and weight (kg) of the catches on the Bagan tancap. The composition of the catch on the Bagan tancap for the species caught is squid (Loligo sp) and Curvespine cuttlefish (Sepia recurvirostra) which are the main catch (HTU) while Starry triggerfish (Abalistes stellaris), mackerel (Rastrelliger brachysoma), Yellowtail scad (Atule mate), and Doublewhip threadfin bream (Nemipterus nematophorus) are by-catch. Based on the results, it can be concluded that blue light is a good color for catches in the form of number (fish) and weight (kg) on ​​the Bagan tancap fishing gear.
