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.

Urban Form has become necessary for city planning management to see the sustainability of a city. A better understanding of different urban forms is imperative to facilitate the evolution of cities towards a more sustainable urban development trajectory in the future. The study aims to analyze the dynamics of urban form and the changes in land cover within the peri-urban area of Surakarta City, which is directly influenced by the development of Surakarta City. The analysis was conducted from a landscape ecology perspective, employing a spatial metrics approach at the landscape level to assess the dynamics of urban form using quantitative descriptive, including a spatial approach. A similar approach was adopted at the class level in order to examine the dynamics of land cover changes. The results of the image analysis were validated using the Kappa index, yielding an image accuracy level of 0.86 (86%). The results of this study show that the urban form in the peri-urban area of Surakarta City tends to move towards a compact urban form. Meanwhile, each land cover, vegetation, and water body become increasingly fragmented, with areas becoming narrower as time passes. Built-up and agricultural land are becoming more compact and concentrated along with development. In conclusion, the dynamics of urban form in the peri-urban area of Surakarta City tends to lead to compact urban form.

Urbanisasi yang masif di Kota Surakarta telah mendorong peningkatan area terbangun dan alih fungsi lahan di Daerah Aliran Sungai (DAS) Kali Boro, memicu eskalasi masalah genangan akibat sistem drainase eksisting yang inadekuat. Meskipun banyak studi drainase perkotaan modern mengadopsi model numerik canggih dan solusi berbasis alam, studi ini secara strategis memilih pendekatan hidrologi-hidraulika klasik (Log Pearson Tipe III, Mononobe, Rasional, Manning) untuk mengatasi keterbatasan data spesifik dan sumber daya di tingkat mikro perkotaan tropis, sekaligus menawarkan solusi yang relevan dan aplikatif bagi Pemerintah Kota Surakarta. Pendekatan ini mengisi kekosongan literatur terkait implementasi master plan drainase mikro komprehensif di kota tropis yang masih mengandalkan data primer dan metode yang terjangkau. Penelitian ini bertujuan untuk menganalisis kondisi drainase mikro eksisting, menghitung debit banjir rencana (T = 2, 5, 10 tahun), mengidentifikasi akar permasalahan, dan menyusun master plan drainase mikro di DAS Kali Boro. Hasil analisis menunjukkan bahwa kapasitas saluran drainase eksisting hanya mampu menampung sekitar 72,5% dari debit banjir rencana untuk kala ulang 5 tahun, diperparah oleh penyempitan, sedimentasi, dan penumpukan sampah. Implementasi master plan yang diusulkan, meliputi normalisasi, peningkatan dimensi saluran, perbaikan gorong-gorong, pengelolaan sedimen dan sampah, pembangunan sumur resapan, serta adopsi drainase berwawasan lingkungan, diproyeksikan mampu mengurangi luasan genangan hingga lebih dari 50% di area prioritas. Studi ini menegaskan relevansi pendekatan konvensional yang terjustifikasi dalam konteks lokal, memberikan kontribusi signifikan dalam perencanaan ketahanan banjir di DAS mikro perkotaan tropis, dan dapat menjadi acuan kebijakan adaptasi iklim Kota Surakarta.

Sebanyak 80% masyarakat Desa Dersono, Kecamatan Pringkuku, Kabupaten Pacitan berprofesi sebagai petani. Desa Dersono secara geologis berada dikawasan Karst Gunungsewu. Kawasan karst identik sebagai kawasan yang kering dan tandus dikarenakan didominasi pelorongan batuan karbonat sehingga air hujan yang jatuh kepermukaan mudah diloloskan kelapisan bawah lebih dari 50 meter. Sehingga mengakibatkan hasil pertanian disana kurang optimal. Meskipun kawasan karst identic kering dan tandus, perannya sebagai pengatur iklim dengan fungsi penyerapan karbon dioksida atmosfer dan keindahan morfologinya menjadi keunggulan yang tidak ditemukan pada kawasan lain. Salah satu potensi keindahan morfologi kawasan karst di Desa Dersono ialah keberadaan Sungai Maron yang dijadikan sebagai objek pariwisata sehingga dapat meningkatkan pendapatan masyarakat selain dari hasil pertanian. Namun disatu sisi, pemanfaatan kawasan karst untuk aktivitas pertanian maupun pariwisata berpeluang merusak ekosistem kawasan karst, sehingga fungsi vital maupun keindahannya terganggu. Perlu dilakukan pengelolaan kawasan karst berkelanjutan sehingga kegiatan pariwisata yang menunjang perekonomian masyarakat dapat dijalankan dan kelestarian lingkungan juga tetap terjaga. Pemahaman mengenai pengelolaan pariwisata kawasan karst yang berkelanjutan dilakukan melalui Focus Group Discussion (FGD) bersama Pokdarwis Sungai Maron dan perangkat Desa Dersono. FGD diawali dengan pemberian materi terkait ekosistem kawasan karst dan pengelolaan pariwisata alam berkelanjutan. Kemudian dilanjutkan diskusi dengan anggota Pokdarwis dan perangkat desa yang hadirGuna mengukur ketercapaian dilakukan pre test dan post test berkaitan dengan pemahaman pengelolaan kawasan karst. Anggota Pokdarwis dikategorikan kedalam kelas pamahaman sangat rendah, rendah, cukup, tinggi dan sangat tinggi. Hasil pre test menunjukkan 3% termasuk kategori sangat rendah, 13% rendah, 22% cukup, tinggi 25% dan sangat tinggi 37%. Kemudian dari hasil post test menunjukkan tidak ada anggota Pokdarwis yang masuk kategori sangat rendah dan rendah, kategori cukup berkurang menjadi 7.5%, kategori tinggi naik menjadi 30% dan kategori sangat tinggi naik menjadi 62.5. Sehingga dapat disimpulkan bahwa Pokdarwis Sungai Maron sudah meningkat pemahamannya mengenai pengelolaan pariwisata kawasan karst bekelanjutan As many as 80% of Dersono Village, Pringkuku District, and Pacitan Regency work as farmers. Dersono Village is located in the Gunungsewu Karst area. Karst areas are identified as dry and barren because carbonate rock tunnels dominate them, so rainwater that falls on the surface can easily escape to the lower layers of more than 50 meters. This results in agricultural yields that need to be more optimal. Even though karst areas are identified as dry and barren, their role as climate regulators with the function of absorbing atmospheric carbon dioxide and their morphological beauty are advantages that are not found in other areas. One potential beauty of the morphology of the Dersono Village karst area is the Maron River, which is used as a tourism object to increase people's income apart from agricultural products. However, on the one hand, using karst areas for agricultural and tourism activities can damage the ecosystem of the karst area so that its vital functions and beauty are disrupted. It is necessary to carry out sustainable management of karst areas so that tourism activities supporting the community's economy can be carried out and environmental sustainability is maintained. Understanding sustainable tourism management in karst areas was carried out through Focus Group Discussions (FGD) with Pokdarwis Sungai Maron and Dersono Village officials. The FGD began by providing material related to karst area ecosystems and sustainable natural tourism management. They then continued discussions with Pokdarwis members and village officials who were present. Pre-tests and post-tests related to understanding karst area management were carried out to measure achievements. Pokdarwis members are categorized into very low, low, moderate, high, and high understanding classes. The pre-test results showed that 3% was in the very low category, 13% was low, 22% was sufficient, 25% was high, and 37% was very high. Then, the post-test results showed no Pokdarwis members in the low and low categories; the moderate category decreased to 7.5%, the high category increased to 30%, and the high category increased to 62.5. So, the Maron River Pokdarwis has improved its understanding of sustainable tourism management in karst areas.

Program Satuan Pendidikan Aman Bencana atau SPAB merupakan usaha preventif dan pengurangan dampak bencana yang berlandaskan hukum pada peraturan Kepala BNPB Nomor 4 Tahun 2012 tentang Pedoman Penerapan Sekolah/Madrasah Aman Bencana. Kecamatan Ngargoyoso merupakan wilayah rawan bencana. Data terbaru menunjukkan sebanyak 72 bencana longsor di Kabupaten Karanganyar per tahun 2023 didominasi oleh Kecamatan Ngargoyoso. Bencana longsor ini turut menimpa SDN 01 Berjo hingga menimbulkan kerusakan dua bangunan ruang kelas pada tahun 2021. Tentunya hal ini menjadikan program SPAB sangat penting untuk diterapkan utamanya kepada siswa Sekolah Dasar yang merupakan kelompok masyarakat yang masih sangat memerlukan bimbingan dari gurunya. Berdasarkan permasalahan yang ada Grup Riset Geografi Terapan Pendidikan Geografi FKIP UNS bekerjasama dengan UPT Pendidikan Kecamatan Ngargoyoso untuk melakukan Sosialisasi Satuan Pendidikan Aman Bencana (SPAB) dan Simulasi Mitigasi Bencana. Kegiatan ini bertujuan untuk meningkatkan kapasitas guru Sekolah Dasar mengenai SPAB. Metode yang digunakan adalah ceramah, simulasi mitigasi bencana dan melakukan pre-test dan post-test. Hasil menunjukkan terjadi peningkatan signifikan pemahaman guru SD terkait SPAB.
