Abstract

The urban areas of Yogyakarta and its surroundings have experienced highly dynamic growth. Therefore, research is needed to analyze urban development, starting with land cover and land use analysis using Landsat TM and Landsat 8 OLI imagery. Random Forest (RF) classification, a machine learning-based method, was employed to accelerate the land cover and land use classification process. This study combines the Random Forest and Landscape Expansion Index (LEI) methods to analyze land use changes and urban growth patterns. LEI was utilized to identify urban development types, such as outlying (diffusion), edge expansion, and infilling.  The study highlights the roles of RF and Google Earth Engine (GEE) in land cover and land use classification. The results show that Yogyakarta and its surrounding urban areas are predominantly expanding outward, following an edge expansion pattern, especially toward Sleman and Bantul regencies. Additionally, infilling growth is observed in Gondomanan and Gondokusuman sub-districts, which are already densely populated areas. Outlying development patterns were found in Sleman and Bantul regencies, occurring far from the Yogyakarta city center.  This study underscores that the combination of RF, GEE, and LEI is an effective method for analyzing urban growth patterns.

Abstract

This research is a research and development that produces learning media based on the media feasibility and effectiveness. The resulting product is a web-based map learning media on the material of Geographic Information Systems at Grade XII. This research used the ADDIE development model (Analysis, Design, Development, Implementation, & Evaluation). The instrument used was a questionnaire for validators, teachers, and students. The results of the validation test were 89.56% with valid criteria, which means a trial can be carried out. The results of the student trial obtained a score of 86.58%, while the average student learning outcome was 83.75% and the results of the teacher's trial obtained a score of 95%. The results were categorized into effective criteria. Thus, the media can be used properly.

Abstract

This study aims to improve the accuracy of Manado weather radar data by filtering ground clutter interference originating from reflections of surface objects such as mountains and buildings. The scope of the study includes the analysis of Manado weather radar reflectivity data in 2024, focusing on the North Sulawesi region. The methods used include thresholding techniques to separate weather signals from ground clutter, data processing using the Python programming and the wradlib module, and validation based on Himawari-9 satellite imagery and Automatic Weather Station (AWS) data. Radar data in VOL format is converted to geospatial projections to produce CMAX (Column Maximum Reflectivity) products and integrated with SRTM30 topographic data. The results show that thresholding is effective in reducing ground clutter, with a correlation value between radar rainfall estimates and AWS observations reaching 0.859 (MAE: 0.306 mm/10 minutes; RMSE: 1.283 mm/10 minutes). Mapping the results via Web GIS facilitates visualization of corrected data. The study's conclusion states that this method improves the accuracy of radar interpretation and rainfall estimates. This study provides operational contributions to weather information-based disaster mitigation in the Manado region.

Abstract

Edelweis (Anaphalis longifolia) is one of Indonesia's mountain vegetation that grows at an altitude of 1,000–2,000 meters above sea level and plays a role as a pioneer plant in volcanic soils. Anaphalis longifolia is one of the places in Kelimutu National Park, which spans altitudes of 1,000–1,731 meters above sea level. Using Landsat satellite imagery, the research aims to identify environmental factors influencing edelweis distribution. Data collection was conducted across six tracking routes: Moni, Wologai-Protelindo, Dedumudi, Niowula, Ratebeke, and Saga-Bukit Sokoria, combining field observations with the analysis of Landsat 8 imagery, elevation SHP, rock type SHP, and NDVI values. The results of the study show that the distribution of edelweis is most commonly found at an altitude of 1471-1599 meters above sea level. Meanwhile, the distribution of edelweis is at least at an altitude of 1114-1200 meters above sea level. The types of rocks in the Kelimutu National Park area are young volcanic rocks and the distribution of edelweis tends to be more abundant in areas with moderate NDVI values (0.25-0.35). Environmental factors such as temperature, humidity, sunlight intensity, soil pH, and wind speed play a role in the spread of Edelweis in Kelimutu National Park.

Abstract

Spatial thinking ability in the 21st century is crucial for students to respond to challenges and global competition. While each student possesses different spatial thinking abilities, these abilities are also vulnerable to decline due to the uncertain global conditions. This study aims to analyze spatial thinking abilities based on students' gender through the Spatial Thinking Ability Test (STAT). The research employs a comparative method with quantitative data analysis using a two-sample t-test. The subjects of this study were male and female students at Muhammadiyah Senior High School 1 Karanganyar. Data collection was carried out using a test. The results showed that the average spatial thinking ability score for male students was 181.45, while female students scored 139.10. The Asymp. Sig. (2-tailed) value of 0.000, with a significance value (sig.) < 0.05, indicates that the alternative hypothesis (Ha) is accepted, while the null hypothesis (H0) is rejected. In conclusion, there is a significant difference in spatial thinking abilities, suggesting that male students at Muhammadiyah Senior High School 1 Karanganyar tend to have higher spatial thinking abilities than female students.

The research involved 31 respondents from Welu and Kaisanti tourist attractions. The findings revealed that the existence of tourist attractions in Woloan Satu Utara and Woloan Dua sub-districts influences job transition, with 68% of respondents switching jobs. Forty-eight percent of casual daily laborers, including motorbike taxis, drivers, and construction workers, chose to become tourism entrepreneurs. Sixty-seven percent of respondents switched jobs to earn more income. The study also found that tourist attractions positively impact the surrounding community by providing employment opportunities and promoting various businesses, contributing to the economic development of the area..

Abstract

The Covid-19 pandemic has significantly impacted the management of Pantai Siuri in Toinasa Village, Poso Regency. This research employs a qualitative method, utilizing data collection through observation, interviews, and documentation to analyze the effects on visitor numbers, tourism management, and the role of the government. The study reveals a decrease in income and reservation cancellations due to the Covid-19 pandemic, along with the obligation for tourists to adhere to health protocols. Despite facing losses, the management still keeps the tourist site open to meet daily needs. The government implements health protocols for the safety of tourists, while the village government focuses on cleanliness, beauty, and pollution prevention.

Abstract

The purpose of this study was to evaluate the environmental impact of sea sand mining in Sathean village, Kei Kecil sub-district, Southeast Maluku district. This study focuses on the state of the environment around marine sand mining and the impacts of these activities. Qualitative research is the chosen research method. The results show that marine sand mining damages the biological quality of marine and coastal waters through increased abrasion. Economic income for miners and mining workers increases as a result of social conditions caused by sea sand mining, but decreases for fishing communities due to reduced fish catches and pearl cultivators because pearl growth is not optimal due to damage to the aquatic environment.
