Semarang City is one of the most densely populated cities in Central Java Province, which has experienced land conversion due to increased development. The purpose of this study is to analyze the relationship and influence of urban development on temperature in the urban area of Semarang from 1980 to 2020. Population data, land use changes, temperature change data from 1980 to 2020, and remote sensing images were used.The influence of city development and temperature used inferential statistics, which is a method related to data analysis for forecasting or drawing conclusions about the overall data. Regression analysis is one part of inferential statistics that is widely used in the decision-making process. Semarang is experiencing development, both in terms of physical appearance and population growth. The population continues to increase until it almost doubles over a period of 40 years, which is directly proportional to the increase in temperature in the city of Semarang. The results of the analysis show that the development of the city seen from changes in population and changes in built-up land has an effect on temperature changes in the city of Semarang by up to 69.9%. The spatial distribution of temperature changes shows the direction of the center of Semarang City activities in the Districts of Central Semarang, North Semarang, East Semarang, South Semarang, and Gajah Mungkur, which is also in accordance with the condition of the area, which is also a residential area and the city center.

Abstrak: Ekosistem mangrove memiliki peran penting dalam menjaga stabilitas pesisir dan meredam abrasi pantai. Namun, tekanan antropogenik yang meningkat menyebabkan degradasi mangrove di berbagai wilayah pesisir, termasuk Babulu Laut, Kabupaten Penajam Paser Utara, Kalimantan Timur. Penelitian ini bertujuan untuk menganalisis perubahan tutupan mangrove secara multitemporal serta mengkaji pengaruhnya terhadap dinamika abrasi pantai. Metode penelitian menggunakan pendekatan kuantitatif deskriptif berbasis penginderaan jauh dan Sistem Informasi Geografis (SIG) dengan memanfaatkan citra Landsat Collection 2 Level-2 tahun 2006, 2016, dan 2026. Analisis dilakukan menggunakan Normalized Difference Vegetation Index (NDVI) untuk mengidentifikasi perubahan tutupan mangrove dan Modified Normalized Difference Water Index (MNDWI) untuk menganalisis dinamika perairan pesisir. Hasil penelitian menunjukkan bahwa luas tutupan mangrove mengalami penurunan signifikan dari ±435,1 ha pada tahun 2006 menjadi ±320,9 ha pada tahun 2026, atau berkurang sekitar 26,2%. Penurunan tutupan mangrove tersebut diikuti oleh peningkatan luasan badan air pada periode akhir pengamatan, yang mengindikasikan meningkatnya abrasi pantai. Temuan ini menegaskan bahwa degradasi mangrove berkontribusi terhadap peningkatan kerentanan pesisir terhadap abrasi, sehingga diperlukan pengelolaan pesisir terpadu berbasis pemantauan multitemporal. Abstract: Mangrove ecosystems play an important role in maintaining coastal stability and mitigating beach erosion. However, increasing anthropogenic pressure has led to the degradation of mangroves in various coastal areas, including Babulu Laut, Penajam Paser Utara Regency, East Kalimantan. This study aims to analyze changes in mangrove cover over time and examine its impact on coastal erosion dynamics. The research method uses a descriptive quantitative approach based on remote sensing and Geographic Information System (GIS) by utilizing Landsat Collection 2 Level-2 images from the years 2006, 2016, and 2026. Analysis was conducted using the Normalized Difference Vegetation Index (NDVI) to identify changes in mangrove cover and the Modified Normalized Difference Water Index (MNDWI) to analyze coastal water dynamics. The research results show that the area of mangrove cover experienced a significant decrease from ±435.1 ha in 2006 to ±320.9 ha in 2026, or a reduction of about 26.2%. The decrease in mangrove cover was followed by an increase in water body area in the later observation period, indicating increased coastal abrasion. These findings confirm that mangrove degradation contributes to increased coastal vulnerability to abrasion, necessitating integrated coastal management based on multitemporal monitoring.

The damage to road infrastructure in East Kutai Regency, particularly in Long Pejeng Village, indicates a gap between the region's economic potential and the low quality of basic infrastructure, impacting community mobility and socio-economic activities. However, the current approach to infrastructure development tends to be top- down and often ignores local perspectives, even though the experiences of the community as the primary users are a crucial source of information for understanding the causes of damage. This study aims to analyze community perceptions of the determinants of road damage and identify the dominant factors that emerge in the narratives of residents' experiences. The method used is a qualitative descriptive approach through in-depth interviews, observation, and documentation of 10 key informants. The results show that road damage is influenced by several main determinants, namely: (1) low material quality due to limited village budget; (2) construction that does not meet technical standards such as material composition and layer thickness; (3) vehicle load pressure that exceeds road capacity; and (4) environmental factors such as rainfall, waterlogging, and topographic conditions that accelerate degradation. These findings indicate that material and budget factors are the most dominant determinants, which are then reinforced by technical and environmental factors, forming a recurring cycle of damage. This situation has resulted in increased transportation costs, disrupted community mobility, and reduced regional connectivity. The study concluded that road damage is multidimensional, necessitating integrated development policies that adapt to local conditions and are supported by improved technical quality, strengthened budgets, and community participation in development planning.

This study aims to analyze the social dynamics of residents in the new housing complex of Gria Mahakam City, Samarinda. The focus of this study is on how social interaction, social participation, social capital, and social barriers are formed within a modern housing environment. To address this issue, the study draws upon Blumer’s theory of symbolic interactionism, Putnam’s theory of social capital, and Giddens’ theory of modernity. Data were collected through in-depth interviews, participant observation, and documentation from 30 informants selected through purposive sampling, and were then analyzed qualitatively through data reduction, presentation, and drawing of conclusions. This study concludes that the social dynamics of residents are in a transitional phase toward more stable social cohesion, where social interaction remains limited, participation is fluctuating, and social capital is beginning to develop but is not yet evenly distributed. Social barriers are influenced by individual and structural factors, while contextually, these dynamics are linked to Samarinda’s position as a developing city and a buffer zone for the Nusantara Capital City, meaning that community formation occurs gradually and is influenced by residents’ characteristics as well as regional development.

Ekosistem mangrove memiliki peranan krusial dalam menjaga kestabilan kawasan pesisir, mendukung keberagaman spesies, serta melindungi pantai dari erosi. Namun, peningkatan aktivitas manusia seperti pengembangan budidaya perairan dan perubahan penggunaan lahan pesisir telah menyebabkan penurunan kualitas mangrove di berbagai daerah pesisir. Penelitian ini bertujuan untuk mengeksplorasi penurunan dan pemisahan ekosistem mangrove di Babulu Laut, Kalimantan Timur, dalam rentang waktu 2006 hingga 2026 dengan memanfaatkan teknik penginderaan jauh multitemporal. Citra satelit Landsat dianalisis menggunakan Indeks Vegetasi Diferensial Normal (NDVI) untuk memperkirakan kepadatan vegetasi mangrove dan Indeks Air Diferensial Normal yang Dimodifikasi (MNDWI) untuk menemukan badan air. Hasilnya menunjukkan bahwa luas mangrove menyusut dari sekitar 435,1 ha pada tahun 2006 menjadi 320,9 ha pada tahun 2026, dengan kehilangan sekitar 114,2 ha, atau 26,2% dari total area mangrove yang ada. Analisis MNDWI menunjukkan adanya peningkatan area badan air yang sejalan dengan berkurangnya hutan mangrove. Temuan ini menekankan pentingnya pengelolaan yang berkelanjutan terhadap hutan mangrove dan pemantauan yang terus menerus menggunakan penginderaan jauh dan Sistem Informasi Geografis untuk mendorong perlindungan ekosistem pesisir.

Tropical rivers play an essential role in maintaining biodiversity, providing ecosystem services, and supporting local livelihoods. However, river pollution caused by household waste, market waste, plastic packaging, disposable diapers, organic debris, detergent foam, and riparian degradation accompanied by localized sedimentation has become a major environmental challenge, particularly in Samarinda City, East Kalimantan. This study investigates community-based river conservation initiatives implemented by the Gerakan Memungut Sehelai Sampah Sungai Karang Mumus (GMSS–SKM) and explores the contribution of drone-assisted spatial observation to river conservation. The study employed a qualitative method combined with a spatial approach. Data were collected through in-depth interviews with the head of GMSS–SKM, field observations, documentation, literature review, and visual interpretation of drone aerial imagery. Data credibility was strengthened through source, method, and theory triangulation, while the findings were interpreted using a geographical perspective, particularly the regional-complex approach. The findings indicate that inorganic waste, particularly plastic packaging, disposable diapers, bottles, and food containers, predominated during the dry season, whereas the rainy season increased the accumulation of organic debris, wood fragments, mixed domestic waste, and sediment transported from upstream areas. Drone observations identified waste accumulation hotspots, degraded riparian vegetation, drainage outlets, localized sediment deposits, and river segments with limited ground accessibility. These spatial observations supported the prioritization of river clean-up, riparian greening, environmental education, and future river monitoring. The integration of community participation, local knowledge, and drone-assisted observation provides an effective decision-support approach for community-based river conservation.

This study aims to analyze the effect of using interactive map media on students' spatial literacy skills. The research employed a quantitative approach with a quasi-experimental design in the form of a nonequivalent control group design. The sample consisted of two groups: an experimental class using interactive map media and a control class using conventional learning methods. The instrument used was a spatial literacy test administered through pretest and posttest. Data were analyzed using descriptive statistics and an independent sample t-test. The results showed an increase in the average score of the experimental class; however indicating that the use of interactive map media did not have a significant effect on students' spatial literacy skills. Nevertheless, interactive map media has the potential to enhance students' understanding of spatial concepts when implemented optimally in geography learning.
