This research focused on the application of the design science research approach in terms of developing GeoLab's mobile learning application for Geography Education in the context of higher education in Indonesia. GeoLab facilitates learning in the field of Geography Education on mobile devices. This application supports learning that can be accessed anywhere in higher education. Even this application provides interactive learning media with a 360-degree video display using Virtual Reality, Augmented Reality, and Mixed Reality features. The first part of this paper describes the analysis, design, and implementation of activities related to GeoLab's development. In addition, this study discussed the characteristics and scope of GeoLab's compliance with the nature and ideas of design science research. We evaluated GeoLab' in real learning, and an experiment was conducted with 126 second-year undergraduate students at a university in Indonesia. This study evaluates the feasibility, effectiveness, and ability of GeoLab' in Geography Education. We conducted a Usability Testing test on GeoLab applications'. The purpose of this Usability Testing is to assess the capabilities of GeoLab applications. Testing using Usability Testing, one of the Usability measurement tools, is the USE Questionnaire, which is divided into three main parameters, namely Usefulness, Satisfaction, and Ease of Use. The results of this study show that the GeoLab application can be considered easy to use by users in Geography learning based on the results of Usability Testing using the USE Questionnaire measurement device. This research offers suggestions on how to implement mobile learning that supports learning in the Geography Education curriculum.

Urban areas tend to have significant temperature differences with the surrounding area. The city of Bandung is surrounded by mountains and forms the Bandung Basin. Land cover differences between Bandung City and surrounding area caused a temperature differences that can identified with remote sensing imagery. The aim of this research are to analyse the change of land surface temperature and the vegetation greenness level in Bandung Basin using Landsat multi-temporal image also to identify correlation between surface temperature change with greenness level in Bandung Basin. In Bandung Basin, there is an increase in temperature in various land covers (Vegetation in flat areas, Vegetation in steep and high altitude areas, Water, Built-up area, and Open Land area) from 1990-2018. Meanwhile, there is less green vegetation in Bandung Basin from 1990-2018. The results of the analysis show a better correlation between Land Surface Tempertare (LST) and Simple Ratio Index (SRI) than the correlation between Land Surface Tempertare (LST) and Normalized Difference Vegetation Index (NDVI). The conclution of this research that preservation of vegetated areas can be done in Bandung Basin to address the increasing of Land Surface Temperature.

This study aims to produce a mobile GIS application as a spatial data-based information media for the geopark area at UNESCO Global Geopark Ciletuh Palabuhanratu in a more exciting and informative way. The development process is by Analysis, Design, Development, Implementation, Evaluation (ADDIE). This application offers navigation, interpretive information, digital maps, offers guide route selection for users, geopark areas, geographical diversity, biodiversity, cultural diversity, tourist destinations, and tourist itineraries. In testing using a drawn questionnaire, the system conclusions made by users are asked to be interested in the application.

This study aims to model the development of edutourism at the UNESCO Global Geopark (UGG) Ciletuh Palabuhanratu, Sukabumi Regency. The sample of the study area was Ciemas Subdistrict, Waluran Subdistrict, and Ciracap Subdistrict. Human samples of this study were divided into two groups, namely inhabitants and communities. The number of respondents involved was 126 people (inhabitants) and 3 people (representatives from three communities). There are three variables studied, that is: (1) inhabitants and community involvement in the development of the UGG Ciletuh Palabuhanratu; (2) inhabitants and community support for UGG Ciletuh Palabuhanratu edutourism activities; and (3) the role of inhabitants and community in the development of the UGG Ciletuh Palabuhanratu. Data collection techniques are interviews and questionnaires. Data obtained were analyzed quantitatively descriptive based on research variables. The results obtained are a model for the development of edutourism in the UGG Ciletuh Palabuhanratu which focuses on the role of the inhabitants and the community, increasing social capital, and patterns of regional development. The model will be used as a basis in the process of developing edutourism initiated by the community and supported by the community. The implementation of this model is expected to increase the independence of the community in managing the geopark area as a tourist destination.

Langsa City is a city on the east coast of Aceh that has the fastest growth compared to the surrounding area. However, this has a significant impact on land conversion which reduces environmental quality. Analysis of changes in land use in Langsa City needs to be carried out as a basis for determining development policies. This study aims to analyze changes in land use in Langsa City from 2013 – 2021. The data used in this study are Landsat 8 OLI-TIRS imagery in 2013, 2017, and 2021. These images were analyzed using a supervised classification technique based on band combinations for each land use. The classified land uses are settlements, paddy fields, ponds, mangrove forests, and mixed vegetation. The results showed that there was a significant increase in the settlement area in the center of Langsa City. Meanwhile, other land uses have changed but not consistently. This study concludes that a significant increase in settlement area is due to rapid population growth. The increase in settlement area also has an impact on changes in other types of land use. The researcher recommends that a population growth study be carried out as a basis for determining regional spatial planning.
