Perubahan Iklim Global juga dirasakan di Indonesia. Berdasarkan data curah hujanantara 1978-2005 telah terjadi kecenderungan penurunan curah hujan denganpeningkatan suhu sebesar 0,04 – 0,047° C/tahun. Karst Wonogiri yang terletak diKabupaten Wonogiri selalu mengalami masalah tahunan berupa kekeringan di musimkemarau. Penelitian ini berjudul Dampak Perubahan Iklim terhadap Neraca Air SecaraMeteorologi dengan Metode Thornthwaite-Mather untuk Analisis Kekritisan Air di KarstWonogiri. Tujuan penelitian ini adalah: 1). mengetahui kondisi curah hujan tahunanselama perubahan iklim di Karst Wonogiri, 2). mengetahui nilai kemampuan menahanair/Water Holding Capacity (WHC) di Karst Wonogiri, dan 3). menganalisis neraca airsecara meteorologis berdasarkan metode Thornthwhite Matter di Karst Wonogiri.Metode analisis imbangan air yang digunakan adalah Thorthwaite Mather untukmenentukan ketersediaan air. Hasil penelitian yang diperoleh adalah: (1) Kondisi curahhujan tahunan di Karst Wonogiri masih termasuk kategori sedang, dengan tebal hujantahunan bisa mencapai 2000 mm. Fluktuasi curah hujan tahunan tidak terlalu tinggi (200-500 mm per tahun); (2) Perhitungan nilai WHC sebesar 112,92 menunjukkan bahwakemampuan lahan di wilayah penelitian untuk menyimpan dan mengikat air termasukrendah yang disebabkan oleh jenis tanah yang ada memiliki solum tanah dangkal hinggasedang serta struktur tanah kersai dan pasiran. Jenis vegetasi penutup yang berupapalawija dengan zone parakaran dangkal juga mempengaruhi besarnya nilai WHC; (3)Analisis neraca air secara meteorologis dapat disimpulkan bahwa ketersediaan air daricurah hujan di wilayah ini termasuk cukup tinggi dengan 7-8 bulan yang surplus. (4)Indeks kekritisan air sebesar 0,56 termasuk dalam kategori mendekati kritisKata kunci: Perubahan iklim, imbangan air
Petanahan sub-district has three villages directly adjacent to the sea: Karangrejo Village, Karanggadung Village, and Tegalretno Village. This study aims to analyze the level of tsunami susceptibility in the coastal area of Petanahan District in the Kebumen Regency. Analysis of the level of tsunami susceptibility using assessment methods, weighting, and map overlays using tsunami hazard parameters, including elevation, slope, land use, distance from the shoreline, and distance from rivers. Then the Weighting of the Tsunami Vulnerability Level uses the formula N = Bi X Si, where Bi is the weight on each criterion, and Si is a score on each criterion. The weighting results are then divided into five classes, very low, low, medium, high, and very high. The results of this study indicate that the tsunami hazard in a coastal area of Petanahan Regency consists of a very high class (93.904 ha/8.33%), a high class (567.804/50.35%), and a medium class of (465.962 ha/41.32%). The results of this research on the vulnerability to tsunamis can be used by the community, especially in the research area, to increase preparedness in dealing with tsunami disasters. At the same time, the Government can take policies in carrying out disaster risk reduction activities of a tsunami, especially in the research area.

<p><em>The area of Ngargoyoso Subdistrict, Karanganyar Regency, has geosphere conditions that have the potential to be developed for agribusiness crops, but are prone to landslides. In it’s development, it is necessary to integrate considerations of productivity and land sustainability by considering the carrying capacity of the land through the identification of landslide vulnerabilities. The objectives of this research are: (1) To determine the vulnerability of landslides in the Ngargoyoso District, (2) To determine the direction of land conservation for sustainable agricultural land development in Ngargoyoso District. The unit of analysis is in the form of land unit which is the result of overlapping between rock, soil, slope and land use units. The method of determining landslide vulnerability uses the scoring method of landslide determining parameters. The results of the research were (1) high landslide susceptibility area of 4,797.25 hectares (78.13%), moderate landslide susceptibility area of 1,343.26 hectares (21.87%), and (2) conservation directions in the form of zoning for seasonal agricultural land and manufacturing. terracing by paying attention to the slope and depth of the solum.<strong></strong></em></p>
<em>This study aims to perceptions and responses to flood disaster risk reduction social media in Pasar Kliwon District, Surakarta City, 2020. Utilization of whatsapp social media as a means of delivering information to the public in an effort to reduce disaster risk flooding in Pasar Kliwon Subdistrict, Surakarta City, 2020. the impact of the use of whatsapp social media as a means of delivering information on community efforts to reduce the risk of flood disasters in Pasar Kliwon District, Surakarta.The results of the study are as follows: Perception of flood disaster in Pasar Kliwon Subdistrict, if viewed from the potential of the disaster, it can be categorized as very large. For flood disaster vulnerability is also categorized as flood disaster prone. And disaster mitigation is carried out in the form of responsiveness and preparedness from stakeholders. Here the use of social media as a means of delivering flood disaster information.</em>
<p><em>Tingginya tingkat kerawanan bencana mendorong perlunya membentuk masyarakat yang resilien. Resiliensi masyarakat memberikan kesiapsiagaan bagi masyarakat, menentukan bagaimana cara merespon, dan bagaimana melakukan recovery dalam menghadapi bencana tsunami. Berdasarkan hal tersebut penelitian ini bertujuan untuk mengetahui tingkat resiliensi masyarakat terhadap bencana tsunami di pesisir Kecamatan Petanahan, Kabupaten Kebumen tahun 2020. Penelitian ini menggunakan metode deskriptif kualitatif. Tingkat resiliensi masyarakat terhadap bencana tsunami di pesisir Kecamatan Petanahan tahun 2020 berada pada tingkat resiliensi tinggi (high resilience) dengan tiga indikator tertinggi adalah coastal resource management dengan nilai 99,75%, risk knowledge dengan nilai 83,74% dan warning & evacuation dengan nilai 90,91 %.

Practicum Geographical information systems and remote sensing have become one of the basic competencies in the realm of skills in the geography learning process at the high school level The purpose of this study is to identify problems or obstacles faced by geography teachers in carrying out geographic information systems and remote sensing practicum activities in high schools in Wonogiri Regency this is a qualitative descriptive study with the use of random sampling. Data collection uses a questionnaire about the implementation of geographic information system practice and remote sensing to the teacher. This study uses descriptive statistical analysis techniques to analyze the factors that become obstacles in the application of geographic information system practice and remote sensing in high school. The result is the obstacles factor of geographic information system and remote sensing practicum in in high schools in Wonogiri is (1). Hardware devices that have not been installed software specifically for geography information systems and remote sensing The teacher has a low ability in the geography and remote sensing information system practicum skills and does not coordinate with the teacher or laboratory assistant for Information and Communication Technology (ICT) subjects (3) Insufficient time allocation for practicum and absence of geographic information system and remote sensing practice tests as evaluations
