Abstract

Global warming and associated weather changes, notably the El Niño Southern Oscillation (ENSO), significantly impact marine ecosystems by altering water quality parameters such as chlorophyll-a (Chl-a) and sea surface temperature (SST). These changes are crucial in understanding the biogeochemical and ecological dynamics of marine environments, especially in regions affected by upwelling. This study aims to monitor upwelling events on Satonda Island, a volcanic island with unique central lake and status as a protected area using remote sensing. Utilizing Landsat-8 imagery and machine learning regression techniques—Random Forest (RF), Support Vector Machine (SVM), and Classification and Regression Tree (CART)—this research evaluates the water quality in Satonda waters over a decade (2013– 2023). The RF method emerged as the most accurate in estimating Chl-a and SST, indicating its efficacy in monitoring marine ecosystems with the result (RMSE = 0.309 and 0.274). The analysis reveals seasonal upwelling patterns, characterized by decreased SST and increased Chl-a concentration, with peaks varying annually between June and November. This study highlights the crucial role of remote sensing and machine learning in monitoring the effects of climate change on marine biodiversity. It provides valuable insights into the temporal dynamics of upwelling in the shallow waters of Indonesia.

Abstract

Online learning is a relatively new thing for some teachers in South Kalimantan. It was the first time for these teachers to do online learning since the government took the policy of learning from home due to the disaster emergencies and environmental change. This study aims (1) to determine the perception of geography teachers in South Kalimantan who have just done online learning for the first time, and (2) to determine the quality of online learning that has been implemented based on the mean index value of each factor. The research was designed with a quantitative approach through an online survey of 26 geography teachers who teach 10th grade at the high school level. The sample was selected by Cluster Random Sampling. The questionnaire instrument used a modified the online learning quality index based on teachers and learners’ perceptions (OLQ-TLP). The research time was from December 2020 to February 2021. The results showed that teachers' perceptions of online learning were in a good category. Based on the index value, factors that have good quality are Learner content, Learner interaction, Instruction interaction, Social Presence, and Course design. Other factors still need to be improved, namely the factors of Learner satisfaction, Knowledge acquisition, Learning platform, Instruction, Learning support, and Ability of transfer. Therefore, to improve teachers' expertise in online geography learning on lithosphere material, training with an innovative Digital Education Shifting (DES) approach is needed.

Abstract

The establishment of Kulon Progo as a strategic zone must consider the threat of coastal disasters besides aspiring economic growth and development. By employing Unmanned Aerial Vehicles for data acquisition, this research modeled flood inundation and developed theoretical contributions on tsunami hazard, vulnerability, capacity, and risk, as well as a procedural planning system for reconfiguring land use that emphasized the mitigation aspects. This study found that the tsunami hazard index in Glagah Village was in a low category, dominated by vacant land and sandy land, accounting for up to 25.38% of the total area. Besides, vulnerability and risk in Glagah Village were mostly in a moderate index, while its capacity was categorized as high since the village already had an evacuation route, a notable tsunami early warning system, and was equipped with safety gear. By combining the index values for hazard, vulnerability, and capacity, the tsunami disaster risk in Glagah Village was categorized as moderate. Spatial planning in Glagah Village recommended that the main facilities related to community activities, such as transportation and housing, be located in areas not exposed to the tsunami. This plan allows everyone to evacuate themselves while being reinforced by a security warning system that stays on alert. Furthermore, detailed spatial maps are expected to be useful as instruments for tsunami disaster mitigation at the pre-disaster stage by recommending better land use configurations.

Abstract

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.

Abstract

Erosion was a process that led to decreased land productivity and soil layer depletion. Four factors affected erosion, including erosivity, erodibility, slope and land cover. This study aimed to assess erosion predictions based on the results of field measurements or terrestrial surveys and the RUSLE method. Precet Forest Park was the location of the research facility. Erosion prediction was conducted by measuring slopes using Total Station. The RUSLE technique with five variables was used to calculate erosion values. These factors included the slope factor (LS), plant management index and ground cover vegetation (C), soil erodibility (K), rain erosion (R), and soil conservation measures (P). The calculation results indicated that the erosivity value (R) was 254.5, the K value was 0.46, the average LS value is was 8.39, the C value was 0.1, and the P value  was 0.9. Calculations using the RUSLE method yielded an average value of the amount of eroded soil in Precet Forest Park of 86.37 tons/ha/year with a soil solum depth of >90 cm. Based on the erosion classification, the grade was classified as class II (Medium). In general, erosion was categorized as high to very high in the middle slope areas of the mountain. This was due to land cover characterised by thick vegetation. In addition, the soil management practices also reduced the value of erosion in Precet Forest Park.

Abstract

Effective waste management is one of the key efforts to achieve sustainable tourism development. The purpose of this study was to examine the waste management model in the Bromo Tengger Semeru National Park area, particularly in the Sea of Sand. The results of this study are expected to provide normative benefits to all stakeholders managing Bromo as a tourist destination and serve as evaluation material for addressing waste issues in the Sea of Sand area. The study was conducted in May 2022 using a qualitative method with a descriptive approach. Data collection methods included observation, in-depth interviews, and documentation. The sampling technique used in this research was purposive sampling, or criterion-based selection, considering the validity of information provided by specific respondents with relevant expertise. The primary informants consisted of the management of the Bromo Tengger Semeru National Park, government officials, guides, and the local community. The research findings indicate that waste management in the Bromo destination area is still suboptimal. Existing facilities are insufficiently representative, and utilities related to solid waste need further development. Furthermore, the coordination of waste management efforts has not been effectively implemented. Recommended measures for stakeholders in Bromo Tengger Semeru National Park to improve waste management include: (1) developing waste management systems; (2) restricting the number of visitors to Bromo; (3) enhancing tourism utilities, such as environmentally-conscious signage systems; and (4) developing and maintaining tourist facilities and infrastructure.

Abstract

Flood disasters often result in negative impacts, including damage to property, infrastructure, and loss of human lives. Identifying flood-prone areas and implementing appropriate prevention measures can significantly reduce its adverse effects. Mapping  potential flood  plays a key role in land use planning, early warning systems, emergency response, and flood mitigation efforts. In recent years, the Bedadung Watershed has faced issues of fluctuations in water discharge and it has a potential to cause flooding in Jember regency. This study aims to assess the flood vulnerability level in the Bedadung Watershed using parameter’s scoring and weighting methods, followed by an overlay or merging of each parameter. The research findings indicate that parameters influencing flood potential in the Bedadung Watershed are land use and land cover, slope and elevation area, and soil type. The results showed that the areas which are identified as vulnerable and highly vulnerable are mainly located at low elevations (0-500 m) with tend to be safe from occurring flood even though the level of rainfall is high. On the other side, the vegetation cover areas showed the low vulnerable from flood.
