The Samin watershed which is located in the Mount Lawu area is vulnerable to flood disasters due to human activities. This research was carried out by inventorying parameter data to create a flood disaster vulnerability map using a GIS-based multi-criteria spatial approach. The seven parameters used in flood disaster analysis are Elevation, Slope, Distance from River, Drainage density, Topographic Wetness Index (TWI), Landuse, Rainfall, Type of Soil, Geology. The weight of each parameter is determined using the Analytical Hierarchy Process (AHP) which has the driving factors for flood disasters. The flood hazard map was obtained using a weighted overlay method and grouped into five classes, namely very low, low, medium, high and very high. The results of the analysis show that 11.36% of the study area has a very low hazard, 27.10% has a low hazard, 39.57% has a medium hazard, 20.43% has a high hazard and 1.54% has a very high hazard.

Distance learning that occurred during the Covid-19 period caused problems. Learning geography, which should provide a good quality of spatial thinking, finally gets a problem. Multimedia learning is a representation tool needed in online learning. These conditions improve students' spatial thinking skills by applying Geographic Information Systems (GIS). The development of the learning multimedia uses a 4-D (Four-D) product development model consisting of the phases: define, design, development, and dissemination. Assessment parameter evaluation improves students' spatial thinking skills, considering comparing values between the experimental and control classes using the Independent Sample T-test = 0.05. The results of this study are that GIS-based learning multimedia is feasible to use with the validity test and trial being a score of 4 or is effectively used to improve students' spatial thinking skills with the result = 5,850 > T-table (2,035).

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.

Pedagogy plays an essential role in the learning process. Ecopedagogy and digital pedagogy are two of its derivatives. This study focuses on the combination of the two pedagogical models, namely Eco-Digital Pedagogy (EDY). It proposes to reveal the effectiveness of the implementation of the EDY model on the readiness of prospective 21st century teachers. This study's population was Geography students at Semarang State University (UNNES) in Indonesia. The data obtained were tested by paired t-test and strengthened by the N-Gain test. The results show that the implementation of the EDY model has proven effective in increasing the ability of prospective teachers, namely in: 1) showing the leadership skills, 2) creating an environment that respects the diversity of students, 3) understanding every content they deliver, 4) facilitating learning to their students, and 5) reflecting on their teaching practices. This positive result indicates that the EDY model can be used to further develop the abilities of prospective teachers to generate better outputs in the learning process.

Indonesia's geographical positioning along the 'Ring of Fire' exposes it to frequent seismic activities, making effective disaster mitigation education crucial. Current educational strategies may not adequately foster the necessary empathy and understanding among students regarding the socio-environmental impacts of disasters. This study aims to develop and evaluate a digital learning platform designed to enhance GeoCapabilities in students, particularly focusing on the social-environmental empathy dimension. The objective is to improve students' empathetic responses to disaster scenarios through integrated disaster mitigation pedagogy. Utilizing the design-based research method, this research involved a systematic blend of iterative development and evaluation phases to refine educational interventions. Data collection was achieved through a combination of qualitative feedback from students and quantitative pre-and post-test measures to assess empathy levels. Data analysis involved statistical testing to determine the effectiveness of the digital learning platform in enhancing empathetic capabilities among learners. The research reveals that the digital learning platform (D-Learning), significantly improves students' empathy towards disaster impacts. Students demonstrated a deeper understanding and emotional engagement with the content, highlighting an increase in their ability to empathize with affected communities. The findings suggest that the scalability of D-Learning can be tailored to different regions, providing a valuable tool for enhancing disaster preparedness worldwide. The integration of technology and empathy-focused pedagogy in disaster education could serve as a model for developing similar educational programs globally, aiming to foster a more resilient and empathetic future generation.

This study was conducted to find out: (1) the agrarian history as a milestone of the agrarian policy in Indonesia; (2) the dynamics of agrarian policy as a driving factor for the agrarian reform; (3) agrarian policy as a means of transforming the agrarian reform in Indonesia. This study is a normative juridical legal research with a historical approach, in addition to use conjunctural approach to examine the complex, historically specific, of various agrarian policies. The study concludes that: (1) Agrarian history is an important part of the agrarian policy realization, beginning from Dutch colonialism along with the dominated agrarian resources and the raise of peasant resistance against imperialism, this condition gave rise to the spirit of national movements and the birth of Law Number 5 of 1960 on The Agrarian Basic Law (hereinafter abbreviated to UUPA) as the basis for agrarian policy in Indonesia; (2) Not all the agrarian policies are oriented towards the objectives of the UUPA, often time they cause problems in their application, among others its irrelevant to principles of justice and people's welfare, land tenure disintegration, lack of certainty over the land rights, stand for the capital owners, opening up of foreign investors controlling agrarian sources, the designation of forest areas on people’s lands, nationalization of the plantations, repressive resolution of agrarian conflicts, and land certification which legalizes inequality land tenure structures; (3) agrarian policy is an important part of the process of realizing the agrarian reform, especially in the context of agrarian transformation towards the formation of a 'agrarian' society structure integrated into economic pillars to improve people’s welfare.
