Abstract

The landscape appearance of Srigonco Village is unique. This uniqueness can be used as a means of learning geography. This study aims to analyze the tourism potential and landscape appearance of Srigonco Village as a means of supporting geography learning. The method used is a field survey by making a working map which is then used to identify tourism potential and landscape appearances. Analysis of natural tourism potential was carried out using neighborhood analysis and analysis of landscape appearance using qualitative descriptive. The study's findings indicate that the tourism potential of Srigonco village is dispersed, with clusters of caves and ponor in the center, an elongated area to the south with beaches, and scattered springs around the community. In addition, the research location has fluvial, karst, and marine landscape elements such as caves, rivers, beaches, waterfalls, and biodiversity preservation, can also be utilised for natural tourism. Srigonco Village's topography can be utilized to teach geography, particularly in the study of geomorphology, hydrology, biogeography, disasters, tourism, and socio-culture. The application of geography learning can be carried out through field activities, research, or project-based learning to provide students with the opportunity to learn directly from the environment.

Abstract

Students should be the primary beneficiaries of teachers' TPACK proficiency. This study aimed to investigate the proficiency of pre-service geography teachers in Technological Pedagogical Content Knowledge (TPACK) through the lens of student perceptions. TPACK, a framework that integrates technological, pedagogical, and content knowledge, is crucial for effective teaching in the digital age. By understanding students' perceptions, this research sought to identify areas where pre-service teachers excel and where they might need further development. The respondents of this research were public high school (Sekolah Menengah Atas Negeri/SMAN) students from Langsa City, Aceh Province. The number of respondents involved was 184 students. They came from SMAN 2 Langsa, SMAN 4 Langsa, and SMAN 5 Langsa where the pre-service teacher was placed during their teaching practice. The research method used is quantitative descriptive based on a questionnaire which aims to measure TPACK proficiency in pre-service geography teachers according to student perception. The results of the study showed that pre-service teachers' TPACK proficiency was very good based on the respondents' perspectives, especially in the aspects of pedagogy and geography content knowledge. However, technological knowledge has results at the good level, which is lower than the other two aspects. Based on these results, the recommendation offered is that the technological capabilities of pre-service geography teachers should to be improved to provide a better learning experience for students.

Abstract

The coastal areas of Semarang City have experienced land conversion due to development activities that threaten mangrove sustainability in recent years. The urgency of this research is the need to monitor mangrove density levels to be used as input in its management. The purpose of this study is to analyze changes in mangrove density levels and the occurrence of abrasion in time series using the Google Earth Engine cloud computing model. The research method used visual interpretation and spectral transformation of NDVI and MNDWI to identify spatial distribution, mangrove density and abrasion. The results showed that there was a significant decrease in mangrove area in 2019-2023 with an area of 111.74 hectares. Furthermore, the level of mangrove density is quite dynamic, especially for high density with a decrease in area from 2019 - 2023 with an area of 260.25 hectares, besides that the decline in high density mangroves also occurred in 2015 - 2023 with a decrease in area of 38.73 hectares. Abrasion in the research location was identified in 2 coastal villages, namely Mangunharjo Village with abrasion along 0.88 km (2015 - 2023) and Tugurejo Village with abrasion along 1.04 km, where both areas also experienced a decrease in mangrove area at a high-density level. In conlusion, there has been a decrease in the area and density of mangroves in the study site, one of which has an impact on abrasion.

Abstract

Providing open space in densely populated settlements is challenging due to the lack of open land. In contrast, open space is essential in these settlements as a place for social interaction in highly communal settlements. In addition to these challenges in riverbank settlements, planning open space is also necessary, considering the landscape's characteristics and the settlement's unique culture. This study investigates the potential of alternative spaces as a solution for providing open space. The study began by observing the population's activities to be mapped according to age group and gender. Data were collected in settlements along the banks of the Musi River in Palembang. Identification began by mapping open space on a spatial map showing the location and distribution and the type of open space in the settlement area. Open space is formed informally in various spaces in the settlement. Multiple demographic groups generally use six types of open space. Furthermore, the data was processed using contingency and distribution analysis to see the size of the group in activities in the open space, the activities carried out, and the location of the open space. The results of the analysis show that different needs and patterns of involvement in groups of adults, adolescents, and children must be considered in planning and design. This study concludes that optimizing open spaces according to residents' activity patterns can solve the limitations. Riverbanks have the potential to serve as open spaces, requiring further longitudinal and qualitative research to understand usage patterns and community perceptions.

Abstract

Bali has become Indonesia's leading destination in the global tourism industry, attracting a growing number of investors and privatization efforts. Nusa Dua has been designated as a site for implementing contemporary tourism concepts in Bali, prompting repurposing several areas for new commercial initiatives. The transition has resulted in conflicts among stakeholders over the decades. This study aims to examine methods for addressing conflicts that occur due to Nusa Dua’s spatial changes by identifying the key stakeholders of spatial planning with various interests. The analysis of stakeholders uses qualitative methods that include content analysis, stakeholder analysis, and literature review. DANA software version 1.3.3 is a semi-quantitative analysis used to determine the root cause of the conflicts. The result shows that conflicts over land use decisions are the most contentious in Nusa Dua’s spatial planning policies. This conflict arises due to misunderstanding and misalignment in spatial planning, leading to policy implementation challenges. This study suggests resolving conflicts and enforcing spatial policies by improving stakeholder understanding and communication. A stronger legislative framework for tourism-related development, enhancing stakeholder cooperation schemes, and encouraging sustainable growth are recommended.

Abstract

Tidal marshes play a vital role in coastal ecosystems, functioning in climate change mitigation, water filtration, and protection from coastal erosion. However, mapping and monitoring of these ecosystems is often hampered by difficult accessibility and dynamic environmental conditions. This research aims to improve tidal marsh classification accuracy by applying a Random Forest (RF) algorithm supported by Sentinel-2A satellite imagery. This image provides various spectral parameters and vegetation indices, including B1, GNDVI, BSI, and NDWI. Three RF models with varying parameters were tested to determine their effectiveness in tidal marsh classification. The model with 26 parameters (Model 3) performed best, with the lowest RMSE value of 0.22, the highest AUC of 0.87, and the highest overall accuracy of 95%. These results show that combining critical spectral parameters in the RF model can significantly improve the classification accuracy and biomass estimation in tidal marshes. This study also confirmed the effectiveness of Random Forest in addressing the challenges of high-accuracy mapping and monitoring. These findings provide a solid foundation for tidal marsh ecosystem conservation and management applications and support the application of machine learning in coastal ecosystem mapping for better and more accurate results.

Abstract

Bantul is one of the regencies in the Special Region of Yogyakarta that was affected by the damage, losses, and casualties due to the Yogyakarta earthquake disaster in 2006. The current condition with the potential for a Megathrust earthquake in the South of Java Island is a special concern in determining the resilience of an area, determining what needs to be improved in preparedness, and providing alternative non-structural mitigation that can be carried out in dealing with earthquakes. This study was conducted to determine the resilience index in social and economic aspects which were then described into six derivative variables. The method used in this study uses literature studies and sequential data analysis. Secondary data is used to calculate the resilience index with predetermined weightings. The results showed that the resilience index in 2021, 2022, and 2023 in the social aspects of 0.985, 0.981, and 0.979 and economic aspects of 1.05, 1.08, and 1.06. During these three years, the index resilience of the social aspect has decreased so mitigation was needed to increase social aspect resilience and prepare the community to face earthquake disasters. One of the non-structural mitigation efforts that can be done is by providing education or training. The economic aspect also needs to be improved with several non-structural mitigation alternatives such as increasing and creating jobs and developing micro, small, and medium enterprises by maximizing the potential of local resources.

Abstract

Global trends indicate that both natural and man-made disasters are on the increase and more people are being affected. This study assessed the trend and monthly distribution of fire disasters in the Sokoto metropolis. Data on monthly records were collected from the Sokoto State Fire Service Department for 2000-2023. Monthly meteorological data for wind speed, sunshine maximum and minimum temperature were collected from the Nigerian Meteorological Agency (NIMET) spanning the period of 2000-2023. Trends were calculated using the Mann-Kendall test. Also, multiple linear regression was used to examine the contribution of weather variables to fire disasters. Results revealed and upward trend. The fire frequency is surging on a trend with positive both monthly and annually. The magnitude of the trend produced statistical P-values of 0.000 for January, February and March while  P-values of <0.0001 were observed on an annual basis. The findings revealed that the critical time for fire incidences are afternoon  hours. The result indicates that February March, January and December constitute the fire disaster-prone period and correspond to the cold dry and hot dry months in the area. Also, maximum temperature accounts for (R2 =0.049), minimum temperature (R2= 0.103), wind speed (R2= 0.004) and Sunshine hours accounted for about (R2= 0.017). There is a need to educate and sensitise the residents through mobile telephony, radio and television broadcasts on the high-risk months identified. Additional fire stations in cluster patterns of distribution should be set up and more fire-fighting personnel should be recruited.

Abstract

Disaster management is mostly done through a technological approach. In addition to the technological approach, disaster management needs to use a cultural, non-technological approach. This study focuses on school-based disaster education as one of the cultural approaches in the area affected by the eruption of Mount Semeru, Lumajang. The purpose of this study was to analyze the implementation of the disaster education model for high school level based on Disaster Safe Schools in the area affected by the eruption of Mount Semeru, Lumajang. The research method used is descriptive statistics to see students' perceptions of 3 aspects of disaster-safe schools consisting of the availability of disaster-safe school facilities and infrastructure, disaster management for disaster-safe schools and disaster risk reduction education for disaster-safe schools. Through Focus Group Discussion (FGD) of social studies teachers, the importance of implementing school-based disaster education was analyzed which includes three aspects of disaster-safe schools. The results in the first aspect regarding the availability of disaster-safe school facilities and infrastructure, on average students have adequate knowledge about disaster-safe school facilities and infrastructure. In the second aspect of disaster management for disaster-safe schools, students view that schools have not fully implemented disaster management and in the third aspect, namely disaster risk reduction education for disaster safety, students consider that it has not been carried out optimally. Meanwhile, for the implementation of disaster education, they prefer a curricular education model by integrating it into relevant social studies subjects. The results of the FGD with teachers revealed that in the first aspect, the four schools did not have adequate facilities and infrastructure. In the second aspect, only 2 schools carried out adequate disaster management, the other two schools were not optimal. In the third aspect of disaster risk reduction education, teachers chose to integrate it into relevant subjects. The conclusion of this study reveals that the school-based disaster education model has not been implemented by all schools in the areas affected by the eruption of Mount Semeru.

Abstract

The delineation of catchment areas plays a crucial role in hydrological modeling, influencing water resource management and flood analysis. However, differences in Digital Elevation Model (DEM) resolutions and processing methods can significantly affect the accuracy of delineation results. This study aims to evaluate the differences in catchment area delineation using Hydrologic Engineering Center-Hydrologic Modeling System (HEC-HMS) 4.12 and Watershed Modeling System (WMS) TOPAZ across three DEM resolutions: DEMNAS (8.29 m), ASTER (30 m), and SRTM (90 m). The methodology involves processing DEM data using both software tools, comparing catchment area, main river length, and basin length derived from each resolution. The analysis reveals that higher DEM resolution results in greater similarity between the two methods. At an SRTM resolution of 90 m, the delineated catchment area is 1474.41 km² (WMS) and 1468.03 km² (HEC-HMS), whereas at an 8.29 m DEMNAS resolution, it is 1462.64 km² (WMS) and 1462.91 km² (HEC-HMS). Additionally, significant differences are observed in the main river length, with 44,368.54 m (WMS) and 34,960.17 m (HEC-HMS) at 90 m resolution, and 58,195.71 m (WMS) and 42,537.38 m (HEC-HMS) at 8.29 m resolution. These findings highlight the importance of selecting an appropriate DEM resolution to ensure accurate and consistent hydrological delineation.
