ABSTRAK Tujuan dari penelitian ini adalah untuk memetakan fasies Gunungapi Merapi yang terletak di DAS Bedog Propinsi Daerah Istimewa Yogyakarta dan bahaya gunungapi yang diakibatkan oleh erupsi Gunungapi Merapi berdasarkan pada fasies gunungapinya. Pengambilan sampel dilakukan dengan sistematic random sampling. Fasies gunungapi ditentukan berdasarkan ciri-ciri litologi dan klasifikasi fasies gunungapi, sedangkan bahaya gunungapi ditentukan berdasarkan identifikasi bahaya-bahaya gunungapi yang dapat menghasilkan batuan-batuan yang menjadi ciri-ciri dari masing-masing fasies. Hasil penelitian menunjukkan bahwa fasies gunungapi di DAS Bedog dari fasies medial dan fasies distal dari Gunungapi Merapi. Hal ini mengindikasikan bahwa pada masa lampau telah terjadi jatuhan awan panas, hujan abu, dan aliran lahar pada fasies medial serta hujan abu pada fasies distal. Kondisi saat ini di mana letak DAS Bedog berada di bawah DAS Krasak dan DAS Boyong (tidak berhulu di puncak Gunungapi Merapi) serta morfologi dan letak DAS Bedog yang berada di belakang Bukit Turgo menyebabkan aliran lahar sulit terjadi.

This study aims to conduct lahar of Mount Merapi on the Boyong River modeling. In addition, this study also to identificate the affected land use of the model, and analyze the risk of loss which are the focus of this study. Lahar modeling was made by using the LAHARZ application from DEMNAS 2018 data and 3 lahar volume scenarios based on the eruption of Mount Merapi in 1994. Identification of affected land use was carried out by using Sentinel-2B 2018 image interpretation with Maximum Likelihood Area (MLA) method, continued by verification using purposive sampling method in the field. Loss risk analysis was done by determining land use that has an economic value, which followed by classifying the level of damage based on the hazard level of lahar. The results of this study showed the effect of volcanic lahar volume and slope of Mount Merapi on surrounding land use. The generalization process in the DEM data did not have a significant difference to the lahar model. River morphology is very influential in this modeling output. Citra Sentinel-2B is suitable for identifying existing land use with the scale used is 1:10.000. The use of affected land was classified into 6 and 3 of which have economic values, namely settlements, buildings, and rice fields. There are 16 hamlets that are affected by the danger of lahar with residential land use which has the greatest total loss, while the use of wetland areas is the most extensive area of this danger.

The Sayung coast is an area subject to the direct influence of coastal disasters, particularly tidal floods. Tis research aimed to investigate the impact of tidal floods on social and economic aspects in Sayung Subdistrict. In order to achieve the aim, data collection was conducted through a systematic process comprising structured interviews carried out using a questionnaire. The research also implemented a random sampling methodology, comprising a total of 23 informants and in-depth interviews were conducted with key informants to augment its comprehensiveness. Following this, the data processing and analysis followed a mixed-method approach where quantitative and qualitative data were analyzed using the Structural Equation Model (SEM) and grounded theory. The obtained results showed that tidal floods had a significant direct impact is able to influence physical health, employment, and property at 62.32%, 69.59% and and 65.43% respectively. Furthermore indirect impact property is able to influence property value by 62.78%, physical health, property damages and employment can influence mental health by 71.71% and physical health, employment can affect mobility by 66.89%. The finding accounts for a new insight that tidal floods have direct and indirect impacts on the community, as examined using the mixed-method approach. The study of tidal flood impacts on poor households in Sayung Coastal, Demak, offers different findings from previous ones. Some previous studies discuss the general effects of tidal floods while disregarding the framework of the direct and indirect impacts of the floods on poor households

This paper examines the local impacts of the 1257 CE Samalas eruption in the Mataram plain in relation to the hydrogeological conditions. Data from several previous studies in the Mataram plain is summarized and then reinterpreted. Data collected from new fieldwork is also presented. This review summarizes hydrogeological conditions into several categories, i.e. stratigraphy, aquifer formation, groundwater quality, and evolution. Two coring data were evaluated, which showed that Mataram plain has a relatively thick alluvial layer with a dominant material of sand mixed with pumice from the reworked deposit of the 1257 CE Samalas eruption. The sediment from this eruption formed a freshwater aquifer layer up to ~18 m deep. Using resistivity data, the aquifer layers in the studied area were characterized as unconfined aquifer, aquitard, and semi-unconfined aquifer. Seven water samples show that the groundwater in the studied area is in good condition, which indicates the bicarbonate water type. The results of the analysis show that the impact of the 1257 CE Samalas eruption on the hydrogeology of Mataram is considered a positive impact, i.e. forming an unconfined aquifer containing freshwater that is good for domestic uses.

This research addresses a significant gap in understanding the social impacts of three major volcanic eruptions in Indonesia: Samalas in 1257, Tambora in 1815, and Krakatau in 1883. While these events have been widely studied in geological and volcanic contexts, their societal impacts and the associated cascading hazards have not been thoroughly compared. Utilizing historical documents that reflect societal memories, including Babad Lombok, Babad Sembalun, Babad Suwung, Syair Kerajaan Bima, and Syair Lampung Karam alongside records from the Dutch East Indies period, this study investigates the community responses and impacts of these catastrophic events. The findings reveal that all documented social memories articulate the communities' reactions and the resultant consequences of these eruptions. Additionally, geological and volcanological data from prior studies were employed to describe the characteristics of past vulnerabilities. Notably, Samalas exhibited the longest recovery process, whereas Krakatau resulted in the highest number of casualties due to its cascading hazards. All events are categorized within the M4 scale of cascading hazards, emphasizing the complexity of these disasters. This research offers critical insights into Disaster Risk Reduction (DRR) programs, highlighting the necessity of integrating historical social memory into modern risk management strategies. By understanding past community responses, DRR initiatives can better prepare for future volcanic events, ensuring a more resilient society.
