Abstract

One of the areas that has become a historical tourist attraction in Klaten Regency is Prambanan District. Prambanan District in the south is directly adjacent to Kapanewon Prambanan which has an Opak Fault. This study aims to microzonate earthquake-prone areas based on microseismic parameters using a portable seismograph at 27 measurement points. Data analysis was performed using the Horizontal to Vertical Spectral Ratio (HVSR) method and the ellipticity curve with the help of Geopsy and Dinver software. The results showed that the range of f0 values was between 0.9 and 18 Hz, which was predominantly included in the Type I classification. The A0 values were in the range of 1.2-4 with the size of the distribution of A0 being dominantly low. The value of Kg in this area is classified as low category with a range of 0.1-14. Prambanan District has vs30 values ranging from 234–1260 m/s which are classified into 3 sites namely B, C, and D. The results of this study indicate that Prambanan District has soil with a thick layer of sediment based on information on the distribution of shear wave velocity values to depth 30 meter. These results are relevant as an effort to mitigate earthquake disasters, especially in vulnerable areas such as Prambanan which has a history of seismic activity due to the presence of the Opak Fault.

Abstract

Yogyakarta is a province in the southern part of Java Island which is close to volcanoes. In this area there are sedimentary materials, such as silt, sand, tuff, breccia, agglomerate and conglomerate so that they are at risk of being affected by local site effects when an earthquake occurs. This study aims to determine earthquake vulnerable zones in several areas in Sleman Regency, including Berbah, Kalasan and Prambanan Districts based on site effect analysis with dominant frequency parameters (f0), amplification factor (A0) and seismic vulnerability index (Kg) using micro seismic data with data of 27 points which are then processed using the Horizontal to Vertical Spectral Ratio (HVSR) method and micro zonation using Geographic Information System (GIS). The results of data processing show that the site class in Sleman Regency is divided into 3, namely SD (Medium Soil), SC (Very Dense Soil) and SB (Rock). Areas with rock formations with soft soil structures are the most vulnerable areas to earthquakes. The lowest

Abstract

Kalasan District and Ngemplak District, located in Sleman Regency, Yogyakarta, are areas with significant seismic risk due to the subduction of the Indo-Australian and Eurasian plates south of Java Island. To support disaster mitigation and land-use planning, it is essential to understand the local geological structure and soil dynamic response. This study aims to evaluate the seismic vulnerability and soil classification using the Horizontal to Vertical Spectral Ratio (HVSR) method and Rayleigh wave ellipticity inversion modeling. Microtremor measurements were conducted at 27 points distributed across both districts. The HVSR method was used to obtain the dominant frequency and amplification values, while the ellipticity inversion of Rayleigh waves was employed to estimate the shear-wave velocity profile and calculate Vs₃₀ values. The results show that the dominant frequency ranges from 0.713 Hz to 18.006 Hz, amplification values range from 0.569 to 4.193, and the seismic vulnerability index ranges from 0.010 to 12.060. Based on these parameters, Sleman Regency is generally categorized as having low to moderate seismic damage potential due to the relatively low amplification and vulnerability index. The Vs₃₀ values indicate a variation in soil site classes, namely medium-density soil (SD) and very dense soil (SC). These findings provide essential data for seismic microzonation, contributing to more resilient urban development strategies.

Abstract

The Afara Field is located around the South Sumatra Basin, which is estimated to contain oil and gas hydrocarbon deposits. The method that can be used for hydrocarbon reserve exploration is the seismic method. Interpretation analysis is carried out by analyzing seismic attributes to determine the amplitude value, shape, and position of seismic waves to identify depositional environments, fluvial or channels, carbonate buildups, to detect fractures and faults, and to provide a direct hydrocarbon indicator (DHI). In this study, the seismic attributes used are the envelope and sweetness attributes to identify the presence of reservoirs, and the ant-tracking attribute is used to identify fault structures around the study area. The results obtained from the analysis carried out on the envelope attribute are the presence of hydrocarbon deposit areas seen from the bright-spot which indicates that the resulting amplitude value is high. The amplitude value has a range of values ​​around 280,000 ms to 440,000 ms located around the UPI-40 and UPI-60 wells. This is validated by the sweetness attribute, which is characterized by the presence of a sweet spot with a value ranging from 60,000 ms to 80,000 ms. The results of the geometric attribute analysis revealed the presence of faults in the study area.

Abstract

This study investigates the long-term impact of climate change on the agricultural sector and land suitability in Central Java—Indonesia’s third-largest rice producer. To project future atmospheric, oceanic, and land dynamics, the research utilizes the Global Climate Model (GCM) under the CMIP6 (Coupled Model Intercomparison Project Phase 6) framework. These models integrate socioeconomic factors through three specific Shared Socioeconomic Pathways: SSP2-4.5, SSP3-7.0, and SSP5-8.5, downscaled to a 25 km resolution. The analysis utilizes historical rainfall and temperature data (1991–2014) as a baseline to evaluate two future windows: the near-future (2027–2050) and the far-future (2077–2100). Employing linear regression and agro-climatic land suitability calculations for rice, the results indicate that while climate change impacts remain relatively stable in the near-term, there is a significant risk for the far-future. Specifically, agro-climatic land suitability is projected to decline in the far-future period, driven primarily by a consistent rise in average annual temperatures across Central Java. These findings serve as a critical evidence-based recommendation for regional agricultural planning and adaptation strategies.   Keywords: Central Java, Agroclimate Land Suitability, Climate Change, Shared Socioeconomic Pathways

Abstract

This study analyzes the impact of forest and land fires on Aerosol Optical Depth (AOD) and fine particulate matter (PM₂.₅) concentrations using in-situ AERONET observations, PM₂.₅ measurements from the Sultan Thaha Meteorological Station in Jambi (2020–2023), and satellite-based AOD data from the Geostationary Environment Monitoring Spectrometer (GEMS). Linear regression and Pearson correlation analyses were applied to establish the empirical relationship between AOD and PM₂.₅, with validation against ground-based observations. The results indicate a strong correlation between AOD and PM₂.₅, with the highest values observed at 340 nm from AERONET (r = 0.7824; R² = 61.21%) and 354 nm from GEMS (r = 0.7802; R² = 60.88%). The derived regression equation was then used to convert satellite AOD into spatial estimates of PM₂.₅. The resulting distribution maps show widespread pollution, with PM₂.₅ concentrations exceeding 80 µg/m³ during the peak fire period in September 2023. This increase coincided with a rise in hotspot activity and low rainfall, while PM₂.₅ concentrations decreased following precipitation events. These findings demonstrate that satellite-derived AOD can be used to estimate PM₂.₅ concentrations and capture the temporal and spatial patterns of air pollution during fire episodes in Jambi Province.   Keywords: Aerosol Optical Depth (AOD); Forest Fire; Air Quality; PM₂.₅; Remote Sensing
