Abstract

Air quality is a crucial parameter in human life. One air quality indicator can be observed through Aerosol Optical Depth (AOD). If these substances are pollutants such as particulate matter, aerosols, and ozone, it is confident that air quality will deteriorate, threatening human health and causing climate change. AOD monitoring can be used as a basis for policymakers and related parties to maintain the stability of air quality in the atmosphere. Many ground observation stations monitor air quality by obtaining data on PM2.5 and PM10 aerosol particles. However, the number of ground stations is limited, resulting in incomplete data. Fortunately, remote sensing satellites have the advantage of covering large areas and providing continuous observations, with the ability to gather information on large-scale aerosol and obtain spatiotemporal distribution. Therefore, this research aims to obtain AOD through Himawari-8 and analyze the spatiotemporal air quality in urban areas of West Java based on AOD. The research methodology used in this study is descriptive analysis with an empirical research approach. Assisted by remote sensing technology and Geographic Information Systems, this research generates AOD data extraction that can be obtained from the new generation satellite of Himawari-8. The distribution of AOD levels and spatiotemporal monitoring in urban areas of West Java is very dynamic depending on anthropogenic activity in a particular area and time. Keywords: Aerosol Optical Depth (AOD), Air Quality, Himawari-8

Abstract

Environmental literacy is considered an achievement of environmental education. Preservice teachers with good environmental literacy knowledge are more likely to align their actions with their understanding. Preservice teachers have two roles: as behavioural models for their students and as members of society. This research is a descriptive study that utilizes the survey method. The subjects of this research are 50 students from the Mathematics Education, Geography Education, and Technology and Informatics Education programs at STKIP Pesisir Selatan, West Sumatera-Indonesia. The data collection instrument in this research is a questionnaire. The data analysis technique used to process knowledge data utilizes the NELA score. This research indicates that students from all three programs have moderate environmental knowledge. The environmental literacy of Geography Education students has a minor standard deviation, showing relatively low variation in the scores. On the other hand, students in the Mathematics Education and Technology and Informatics Education programs have a higher standard deviation, indicating a more significant variation in their science literacy scores. Geography Education students have higher knowledge of ecology and pollution than students from the other two programs. Meanwhile, mathematics education students have the highest scores in environmental problem-solving skills. Keywords: Analysis, Environmental Literacy, Preservice Teacher

Abstract

Tsunamis are natural hazards that have the potential to cause significant damage and losses to the South Coast of Java. As the initial foundation for local spatial planning and risk reduction, preparing a tsunami susceptibility mapping is imperative to minimize the disaster's impact. This study aims to identify the spatial distribution of tsunami susceptibility in Watukarung Village, Pacitan Regency, using the Spatial Multi-Criteria Evaluation (SMCE) method. The variables involved in the modeling include landform, elevation, slope, distance from the shoreline, and distance from the river. The value and weight of each factor were determined using the pairwise technique in the SMCE framework. The research results indicated that the tsunami susceptibility in Watukarung comprises four classes: safe (598.40 ha), low (9.68 ha), moderate (23.92 ha), and high (25.13 ha). The areas most prone to tsunamis are generally identified in the southern part of Watukarung, which is generally associated with beach or alluvial plain landforms, very close to shore, and low land elevation. Ironically, human settlements and coastal tourism are overgrowing in the tsunami-prone zone, highlighting that risk reduction measures must be implemented optimally to anticipate tsunami hazards. As a recommendation, further research must be carried out to comprehensively represent the tsunami risk in the Watukarung coastal region. Keyword: Tsunami, Susceptibility, Spatial Multi-Criteria Evaluation, Watukarung, Pacitan

Abstract

Using a survey method, this study aimed to examine the characteristics of the land and the direction of land usage for cultivating coconuts. The land's features are described in a land map created from the overlapping findings of each land map unit, which serves as a foundation for additional study to fit the environment for growing coconut plants. According to the results of the analytics and planning of the land conservation of coconut crops in Gayo Luwes, for the crops to survive, it is vital to pay attention to soil characteristics such as temperature, rainfall, soil type, and the number of wet months. Gayo Luwes District is a coconut region in the centre of the country. Not only were the results of matching for the coconut commodity in each SST obtained by using map-based planning geographic information systems, but it was also discovered that rainfall ranged from 3100 mm/year, temperatures went from 23oC to 24oC, base saturation was in the very low to low category (3.91% -35.16%), pH H2O is classified as acidic (4.6-4.9), drainage is slightly obstructed, relatively fast and good, slopes are sloping to steep (12%-26 ) and textures with values little fine, smooth and rather rough are the limiting factors dominant. Other findings also suggest that applying organic material in garbage and compost to Red Yellow Podzolic soil in Batanghari, Jambi, increases Ca-dd and base saturation, and liming is done to raise the pH of H2O in soil units. Moderate to high levels of management can improve the slope limiting factor, such as delaying erosion, establishing a terrace, planting according to the contour, and growing covering plants. Irrigation and irrigation systems can assist in increasing the factors that limit rainfall. Keywords: Development, Coconut, Land Suitability, Gayo Lues

Abstract

The availability of tourist maps so far has experienced limitations in presenting attribute data in the form of non-spatial characteristics. Tourism is called quality if it can convey the information the community needs. Among them are location attributes, land use, natural and cultural phenomena history, and interrelationships between spaces. Geographical and cultural features are essential to be used in realizing quality tourism through the availability of information on tourism space areas, such as visualization of landscapes and depth of local cultural knowledge. This study used a qualitative method with data collection techniques carried out through interviews, focus group discussions, landscape documentation, surveys, and observations to determine the geographical position of spatial elements. The results of the study produced Itinerary Maps and geosite distribution, including the Saddang River, Buntu Lindo Batu, Lo'ko Malillin, Buntu Lingkobo, Mount Benteng Alla’, Buntu Karua, and Kalosi Arabica Coffee Cultivation. The row of geosites has a chronology and chronology of formation and is related to the social culture of the people in the Fort Alla’ area. The findings from this study are expected to provide exposure to the public, tourists, and the government to preserve natural and cultural heritage to become a reference in implementing sustainable tourism development in Enrekang Regency. It is necessary to develop a digital-based information system that presents spatial attribute data and ethnographic records that can be accessed online. Keyword: Tourism Geography, Ethnography, Benteng Alla’, GIS

Abstract

Detailed information regarding tidal characteristics in Indonesian waters is not yet available evenly, including in the southern waters of Java. Tides are one of the most essential hydro-oceanographic parameters in water dynamics. Therefore, this study aims to analyze the characteristics of the tides in the southern waters of Java, starting from Banten Regency in West Java to Malang Regency in East Java. Tidal data with measurement intervals every one hour were collected from December 23, 2022, to January 20, 2023, from ten tide stations with details: 1 station each in Banten and Central Java, three stations each in West Java and East Java, as well as two stations in Yogyakarta. Data from each station is then processed using the Admiralty method to obtain tidal harmonic constant and Formzahl values. Based on the tidal harmonic constants' amplitude and the Formzahl values (F), the tidal type in the southern waters of Java is a mixed tide prevailing semi-diurnal (F ranged from 0.64 - 1.34). The tidal range in the southern waters of Java ranges from 178 - 332 cm. In more detail, Banten and Pelabuhan Ratu waters are classified as micro tides (the tidal range is 178 and 182 cm, respectively). At the same time, the rest are categorized as meso tides (tide range between 200 - 400 cm).Keywords: Tidal Type, Admiralty, Formzahl, Tidal Range, Indian Ocean

Abstract

Visualization of volcanic landforms with digital elevation model (DEM) data on the GIS desktop computer has limitations regarding access to the software display function and its use outside the room. This obstacle can be overcome by combining GIS and mobile augmented Reality. However, using digital elevation model data and satellite imagery in augmented reality software has not been widely explored. This study shows a practical way of integrating geospatial data with mobile augmented reality software. This research aims to create an augmented reality prototype to visualize virtual volcano objects. DEM data and satellite imagery create 3-dimensional (3D) objects and provide texture characteristics of volcanic landform objects. Visualization of volcanic landforms is done through an augmented reality (AR) application prototype on an Android smartphone. The experimental results show that augmented reality technology effortlessly combines DEM data and land features from satellite imagery. Evaluation of a smartphone device's manufacturing and installation stages shows results with a "successful" status. Through follow-up testing nine times, the AR prototype showed positive performance in all aspects of distance, angle, and lighting. The final test scenario in the form of responses regarding the application from other users obtained an average value of the "Good" category of 92.8%. In conclusion, these results indicate that the system built can be used in learning. However, further research requires more diverse test scenarios to see how far this application prototype can be used in various conditions. Keywords: Digital Elevation Model, GIS, Augmented Realit, 3D Visualization

Abstract

Bali and Nusa Tenggara are regions where monsoonal wind changes and strange interactions between the ocean and atmosphere influence rainfall. The purpose of this research is to evaluate Integrated Multi-Satellite Retrievals for GPM (IMERG) rainfall data using in-situ observations from Bali and Nusa Tenggara, Indonesia, while considering seasonal variations and the El Nino-Southern Oscillation (ENSO) phenomenon. The study combines rainfall data from synoptic stations with rain gauge measurements over ten years, from January 2012 to December 2021, to obtain more accurate verification results. The study's findings indicate that, apart from the transitional seasons, IMERG data provides substantial estimates of monthly rainfall accumulation with low error values for both light and heavy rainfall. The study also reveals that the islands' complexity and topography can impact each province's validation values. The verification results show excellent accuracy in flat terrain areas and moderate elevations, while performance decreases in regions with high altitudes. These findings are significant because IMERG data can estimate rainfall for regions lacking monitoring stations during specific seasons and active ENSO conditions. Thus, this information can serve as a valuable tool to address the issue of data unavailability in hard-to-access areas and contribute to optimizing water resource management and weather-related disaster mitigation. Keywords: Validation, Rainfall, IMERG, ENSO

Abstract

Sukoharjo District has the highest rice productivity in Central Java. Sukoharjo has a strategic location. It makes this area prone to land use changes. It makes a severe impact on Paddy's productivity. This condition needs to be monitored continually. Remote sensing can provide an efficient and accurate method to solve this condition. Using the NDVI from Landsat 8 imagery and ubinan data, the model can be built to calculate and analyze paddy’s productivity. The steps were 1) interpretation of paddy fields area; 2) calculation of NDVI’s mean values a month before harvesting; 3) interpretation accuracy test; 4) correlation value between NDVI and ubinan data in 2022; 5) calculation of paddy productivity; and 6) analysis. Within a decade (2013-2023), there was a reduction in paddy's yield area for 981.90 Ha. During that period, there was an increase in paddy's productivity, around 38.2 x 103 tons. Almost all sub-districts in Sukoharjo’s yield had been reduced except for Tawangsari and Weru. Kartasura and Grogol have experienced an intensive change in paddy yields to non-paddy yields. Intensive land use changes affected paddy’s productivity. Multi-temporal imagery combined with ubinan data can be used to monitor paddy’s productivity. Forty-one points were calculated for the y (productivity) and x (NDVI value) equation. The equation resulting from this method (y=6.2212x+6.7444) can be used as a reference for calculating productivity in Sukoharjo District in different periods. From different calculations, the accuracy obtained from this method was 86%.Keywords: Landsat 8; NDVI; Paddy’s Productivity; Sukoharjo; Ubinan data
