Abstract

The geological conditions around Bantarujeg District exhibit diverse and intriguing features, especially in the area north to northwest of Cikidang village, characterized by elongated hills and steep slopes bordering the Ciwaru River to the east. Landslide potential in this region is influenced by various factors such as soil types, rock formations, subsurface materials, water saturation, slip planes, and gravity. This research aimed to mitigate landslide risks by analyzing subsurface geological conditions and structures to identify slope slip areas and predict the depth and type of layers beneath the northwest slope of Cikidang village using the Wenner-Schlumberger 2D geoelectric method. Measurements were taken along two lines: the mainline trending NW-SE and the crossline trending NE-SW. On the mainline, the topsoil layer (5.54 - 237 Ωm) is predicted to be less than 7 meters deep, with volcanic fragments (237 - 2,893 Ωm) at depths of 7 – 9.5 meters. Layers deeper than 9.5 meters exhibit resistivity values exceeding 2,893 Ωm. On the crossline, the topsoil layer (6.40 - 261 Ωm) is also less than 7 meters deep, with volcanic breccia (261 - 1,152 Ωm) at depths of 7 – 9.5 meters. Layers deeper than 9.5 meters have resistivity values exceeding 1,152 Ωm, indicating the presence of basaltic breccia in the lower layers.

Abstract

esa Ciwaruga berada di wilayah suburban yang berpotensi mengakibatkan perubahan penggunaan dan kepemilikan tanah kawasan permukiman secara cepat. Kondisi ini berdampak pada upaya pemantauan kepemilikan bidang tanah permukiman yang perlu dilakukan pembaruan data bidang tanah. Proses untuk memetakan dan mengetahui letak, batas, dan luas suatu bidang tanah kawasan permukiman di atas peta tidak terlepas dari beberapa kendala. Khususnya pemetaan dengan metode direct techniques seperti terestrial ataupun survei satelit memiliki keterbatasan dan kendala dari segi teknis, waktu, biaya, dan sumber daya manusia. Kendala tersebut dapat diatasi dengan metode pemetaan indirect techniques dengan data foto udara. Metode ini dapat memetakan dan memperbarui data bidang tanah dengan lebih cepat untuk cakupan wilayah yang lebih luas. Terdapat dua metode untuk pemetaan bidang tanah menggunakan data foto udara yaitu metode digitasi on-screen dan metode object-based image analysis (OBIA). Melalui penelitian ini, akan dikaji analisis efektivitas kedua metode dalam memetakan bidang tanah kawasan permukiman menggunakan data foto udara. Analisis ini menggunakan pengujian toleransi ketelitian planimetrik luas dan jarak berdasarkan peraturan Badan Pertanahan Nasional. Toleransi kesalahan luas adalah +- 0.5  luas sebenarnya, dan toleransi kesalahan jarak adalah <= 0.3 mm pada skala peta. Berdasarkan pengujian dan perbandingan ketelitian luas dan jarak, jumlah bidang, dan bentuk bidang yang dihasilkan, dapat dikatakan bahwa pemetaan dengan metode digitasi on-screen lebih unggul dari metode object-based image analysis (OBIA). Dari penelitian ini dapat disimpulkan bahwa peta bidang tanah hasil digitasi on-screen dapat dipertimbangkan menjadi peta bidang dalam sertifikat tanah, karena memenuhi toleransi kesalahan planimetrik luas dan jarak berdasarkan peraturan Badan Pertanahan Nasional.

Abstract

This systematic literature review examines the use of ArcGIS StoryMaps in the context of high school geography education, with a particular focus on the methods of implementation, the resulting impact, and the benefits derived from their use. ArcGIS StoryMaps provides an innovative platform for the creation of interactive and engaging geographic content, given the increasing influence of digital tools in the educational landscape. The findings of the eleven studies selected from the 290 articles are presented in this review. The studies highlight the ways in which ArcGIS StoryMaps enhances student engagement, spatial thinking, and comprehension of geographic concepts. The tool is compatible with a variety of learning approaches, including project-based, inquiry-based, and case-based learning. Furthermore, it facilitates digital learning environments through immersive and dynamic presentations. The findings indicate that ArcGIS StoryMaps not only facilitates students' comprehension and creative capabilities but also assists educators in enhancing their pedagogical approaches and geographic expertise. However, the limitations of the study, such as the focus on positive effects, may affect the generalizability of the findings. It would be beneficial for future research to address these limitations by examining potential implementation challenges. In conclusion, ArcGIS StoryMaps has the potential to revolutionize geography education by enhancing the learning process in both engagement and efficiency.
