Abstrak. Artikel ini mengkaji toponimi di kawasan karst Kecamatan Giritontro, Kabupaten Wonogiri, Jawa Tengah. Penelitian ini berfokus pada bagaimana proses penamaan tempat di wilayah karst mencerminkan karakteristik geografi, sejarah, dan budaya masyarakat setempat. Toponimi tidak hanya berfungsi sebagai penanda geografis tetapi juga sebagai cerminan interaksi manusia dengan lingkungannya. Metode penelitian yang digunakan adalah deskriptif kualitatif dengan pengumpulan data melalui observasi lapangan, dan wawancara mendalam. Data yang dikumpulkan mencakup nama-nama objek alam seperti bukit, gua, dan mata air, serta nama-nama buatan manusia. Hasil penelitian menunjukkan bahwa penamaan tempat di kawasan karst Giritontro banyak dipengaruhi oleh karakteristik morfologi dan hidrologi karst. Misalnya, istilah seperti "giri" dan "gunung" digunakan untuk menyebut perbukitan dan kubah karst, sedangkan "luweng" dan "telaga" digunakan untuk menamai doline atau lubang runtuh. Selain itu, istilah penamaan hidrologi juga digunakan seperti istilah “Teleng”, “Sumber/Mber”, “Dung” dan “Kali”. Proses morfologi kata seperti blending, coinage, dan compounding ditemukan dalam pembentukan toponim di wilayah ini. Penelitian ini menyoroti pentingnya pemahaman tentang sejarah dan kearifan lokal dalam konservasi lanskap karst, yang unik karena struktur hidrologi dan morfologinya. Hasil kajian ini juga menunjukkan bahwa toponimi dapat menjadi alat penting untuk memahami dan mendokumentasikan perubahan lanskap dan penggunaan lahan di kawasan karst, serta dapat menginspirasi masyarakat untuk menjaga warisan geologi dan budaya mereka. Abstract. This study explores toponymy in the karst region of Giritontro District, Wonogiri Regency, Central Java, focusing on how place-naming processes reflect the local community's geographical, historical, and cultural characteristics. Toponymy acts as both a geographical marker and a representation of human-environment interaction. The research employs a qualitative descriptive approach, with data collected through field observations and in-depth interviews. The data includes names of natural features, such as hills, caves, springs, and man-made locations. Findings reveal that the naming of places in the Giritontro karst region is strongly influenced by its unique morphological and hydrological characteristics. For instance, terms like "giri" and "gunung" refer to hills and karst domes, while "luweng" and "telaga" denote dolines or sinkholes. Hydrological terms such as "Teleng," "Sumber/Mber," "Dung," and "Kali" are also commonly used. Additionally, word formation processes such as blending, coinage, and compounding play a significant role in toponym creation. This study underscores the importance of understanding local history and wisdom in conserving karst landscapes, renowned for their unique hydrological and morphological features. Furthermore, it demonstrates that toponymy is a valuable tool for documenting and understanding landscape changes and land use while inspiring communities to safeguard their geological and cultural heritage.

Landslides are natural events that can be worsened by human activities, leading to significant destruction of life and property. In Tawangmangu District, situated on the slopes of Mount Lawu, the landslide risk is amplified due to factors such as volcanic soil, steep terrain, and high rainfall. This research seeks to map landslide hazards in the area by utilizing a Geographic Information System (GIS) and the Analytical Hierarchy Process (AHP), combining both static and dynamic factors contributing to landslide occurrences. The study considers seven critical factors: slope, distance from roads, geology, land use, soil type, rainfall, and proximity to geological faults. Expert opinions are used to assign weights to these factors, which are then integrated into a GIS model to assess susceptibility to landslides. The area is classified into five risk zones. The results show that 21.97% of the region faces high and very high risks, while 39.57% is moderately vulnerable. The highest-risk areas are those with steep slopes and significant human activity, such as road construction and land-use changes for tourism. Model validation, comparing the predicted landslide zones with actual landslide locations, shows that over 75% of landslides occurred in high and very high-risk areas, confirming the model's accuracy. This study underscores the importance of sustainable land use planning, effective infrastructure management, and vegetation preservation in reducing landslide risks. Future mitigation efforts should focus on monitoring land use changes, strengthening vulnerable infrastructure, and enhancing early warning systems to minimize further landslide damage in the region.

This study investigates the spatial dynamics of Karst Rock Desertification in the tropical karst region of Tepus District, Gunungkidul Regency, using Sentinel-2A imagery and remote sensing indices including NDVI, NDRI, FVC, and Fr. Although various studies have examined KRD in different karst regions using NDVI or NDRI individually, few have integrated multiple indices to capture both vegetation degradation and rock exposure simultaneously. Moreover, most previous studies rely on medium-resolution imagery like Landsat, which limits spatial detail, and rarely focus on the tropical karst of Indonesia. KRD, characterized by soil degradation and vegetation loss in karst landscapes, poses significant ecological threats due to its rapid and often irreversible impacts. The research employed a quantitative descriptive method combined with spatial-temporal analysis using Google Earth Engine and ArcGIS to assess land cover changes between 2019 and 2024. The analysis focused on identifying rock desertification by utilizing NDVI with FVC and the NDRI with FR. Field observations validated these findings, showing clear distinctions in soil depth and vegetation between degradation levels. The results showed significant changes in vegetation cover and rock exposure between 2019 and 2024. The Non-Rocky Desertification area decreased from 25.65% to 9.39%, while the Potential Rocky Desertification zone increased from 73.75% to 90.12%. In terms of vegetation, the “Nothing” category rose from 6.42% to 2.51%, while Moderate vegetation cover declined from 23.20% to 23.51%, and Extremely Severe decreased from 9.68% to 19.11%. These findings indicate that approximately 40% of the study area is now affected by moderate to severe desertification, emphasizing the urgent need for conservation and sustainable land management. The study highlights the critical role of vegetation management and sustainable land use to curb the advancement of desertification. These findings contribute to understanding karst ecosystem vulnerability and inform future ecological restoration strategies.
