No full textRoad Transportation Development and Land Use Changes in Semarang City, Central Java, Indonesia
No full textThis research aims to make a historical mapping of the development of road infrastructure and the impact on land use changes. A historical analysis was conducted based on the documents and reports of transportation development, road construction, and urban planning in Semarang City, the capital city of Central Java, Indonesia. From a historical perspective, the transportation development and the land use change of Semarang City were determined by economic activities from the early period of colonialism, especially when this city was devoted as a port city in Java with massive coastal inhabitants. Along with this economic activity, ports and roads were built, accelerating the city’s development until the mid of 20th century. Road construction generated urban problems such as rapid urbanization, and environmental problems. Meanwhile, the road construction also accelerated the city agglomeration, connecting Semarang City with other cities on the Java North Coast. However, in the 1990s the symptom of the use of private transportation occurred in Semarang which became the most critical issue in the later periods

Employing technology capable of delivering comprehensive landscape information is crucial for effective environmental education. Utilizing Unmanned Aerial Vehicles (UAVs) and 360-degree panoramic cameras represents a judicious technological choice, which can be seamlessly integrated into virtual tours. This research aims to develop a Mobile Virtual Tour (Movie-Tour) as a medium to support learning, especially for materials regarding environmental geography. The research and development (RnD) method is used in research with the ADDIE model (Analysis, Design, Development, Implementation and Evaluation). Data collection for the development of the product involved conducting a need assessment, performing validation tests and conducting trials with students. To gather field data for creating environmental geography materials for the Movie-Tour product, we utilized an Unmanned Aerial Vehicle (UAV) and a 360-degree stereoscopic camera. The results demonstrate that Movie- Tour is an educational medium capable of delivering an immersive learning experience and comprehensive materials, allowing for the virtual visualization of real-world conditions in the field. This capability enhances students’ engagement in exploring physical geography conditions, fosters independent knowledge acquisition, and nurtures their innate curiosity. Movie-Tour stands as a potent and practical educational tool, offering an effective and secure learning experience for students, eliminating the need for direct field visits
Surface Runoff Analysis for Infiltration Well to Maintain Groundwater Availability
No full textRapidly increasing housing demand has led to significant land-use changes, even in rural areas like Pakintelan Village. One major consequence of these changes is increased surface runoff, which can contribute to environmental issues. This study aims to analyze the surface runoff in Pakintelan Village and estimate the number and placement of infiltration wells needed to effectively manage the runoff. Using a combination of arithmetic methods based on rational equations and Geographic Information System (GIS) tools, the research identified the main catchment areas in Pakintelan Village. The GIS data used in the analysis had a vertical accuracy of 50 cm and a horizontal accuracy of 7 cm. The results show that the village produces approximately 3.89 m3/sec of runoff, with the majority originating from mixed garden areas. To mitigate this, infiltration wells should be placed at the lowest location in these mixed gardens to reduce surface runoff. This study provides a novel assessment of runoff and water absorption strategies in Pakintelan Village, offering practical insights for future land and water resource management in similar settings
GIS-MULTI CRITERIA ANALYSIS TO ENHANCE PLANNING JUDGEMENT FOR NEW TOWNSHIP DEVELOPMENT
No full textUrban development is increasingly encroaching on hillsides, negatively impacting agriculture, particularly in developing countries like Malaysia, where flat land is scarce. To address this, the study aims to develop a GIS-based land suitability model that considers accessibility, environmental threats, and economic factors for optimal hillside development locations. Using multi-criteria decision analysis (MCDA) and the analytic hierarchy process (AHP) through Expert Choice software, key factors like accessibility, topography, land cover, and economics were analyzed. The study identifies Township 1, located 4.23 km northwest of UiTM, as the most suitable site for new development, considering current land use and proximity to key institutions. This model provides a framework for hillside development in Malaysia and other developing countries
The Relationship between Population Dynamic and Garang River Upstream Environment in Central Java, Indonesia
No full textThe interaction of the human population with nature can cause environmental damage such as the degradation of the watershed carrying capacity. Therefore, this study aimed to analyze the relationship between population dynamic and the upstream environment alongside Garang River using four villages including Munding, Lerep, Kalirejo, and Pakintelan. Data were collected from several stakeholders including selected heads of households supported by key informants such as community leaders and the river care communities using field observation, a household survey through questionnaires, in-depth interviews, and documentation. The households used as samples were selected through proportional random sampling and the data retrieved were analyzed through a descriptive quantitative method which involved the cross-tabulation of household data on economic activities and environmental management practices. It was discovered that 1) the population of the Garang River’s upstream was very dynamic with growth rates varying from 1.05% to 3.93%, 2) the main livelihood of the population and dominant land use was the agricultural sector, 3) the community realized that the harmonic relationship with the environment was a critical condition to support farming activities and fulfil daily necessities, and 4) the society kept maintaining the river through different activities such as "bersih sungai" or river cleaning and "sedekah bumi" or thank-giving to the environment. Moreover, the harmonic relationship between the people and the river environment is in form of several activities. These included waste management, cleaning rivers, maintaining clean waterways, actions to create a clean and healthy environment, and joining the efforts to care for the environment. The harmony was observed to have been realized through the integration of diversity, interdependence, unity, and the value of providing care
Rural–Urban Transformation and Landuse Dynamics in Gunungpati on the Northern Flank of Mt. Ungaran, Semarang, Indonesia
No full textMost of the northern flank of Mt. Ungaran is subject to intensive land occupation that makes landuse change inevitable. The research objectives of this study were to examine the spatial patterns of land-use dynamics from 1997 to 2018 and to analyze their impact on the rural–urban structure of Gunungpati sub-district using on-screen digitation. Rural–urban structure was analyzed based on landuse composition by area in each village. This research revealed that forest areas and paddy fields were decreasing year by year. Over the study period of 21 years, Gunungpati experienced deforestation of 1,777 ha and increase in built-up area of 1,295 ha, forcing shifting in rural structure. Most villages that were categorized as rural frame zones in 1997 had changed into urban–rural frame zones by 2018. This situation must be controlled, since much of Gunungpati territory plays a significant role as a groundwater recharge zone for the Semarang lowland area.
The Study of Anthropogenic Disturbance on Geopedogenetic Process at the Lower Slope of Mt. Ungaran, Indonesia; Estudo da Perturbação Antropogênica na Vertente Inferior do Mt. Ungaran, Indonésia
No full textVolcanic rocks mining activity will undoubtedly remove vegetation cover and cause the physical environment changes. Revegetation effort as part of land rehabilitation program then often found many obstacles because it was mostly conducted without adequate knowledge of detailed morphology and soil characteristics at the post-mining area. This study investigates the geopedogenetic changes, including land surface morphology, recent geomorphic processes, and soil properties caused by andesite rocks exploitation at the northern flank of Mt. Ungaran, Central Java Province of Indonesia. A digital terrain model was firstly generated from small format aerial photography acquired by an unmanned aerial vehicle (UAV) to identify the surface morphology changes due to the mining. Soil observation on field and laboratory tests were conducted from samples at the affected and unaffected mining areas to analyze the changes in physicochemical properties. This research exhibits that the mining activities have altered a single 60 m convex hill into a complex land surface morphology consisting of the sloping zone, basins, and flat area. Human disturbance on the pedogenetic process at the mining area is in the form of parent material alteration that makes them return to the early stage of soil development and topsoil reduction that modifies its genetic horizons. In addition, the changes in surface morphology and the absence of vegetation cover right after the mining ends also triggered new geomorphic processes in the form of incision and deposition on slopes and basins respectively. The finer deposit layers then become a new parent material at the basin zone. Soil laboratory data demonstrate that the affected soils tend to have a high level of base saturation for more than 10, but lower C-organic ca. 0.71 on Horizon A and 0.08 on Horizon B and N-total levels ca. 0.15 on Horizon A and 0.12 in Horizon B, which result in a less favorable environment for supporting vegetation growth. A precise surface morphology design, extra soil surface protection, and organic matter enhancement could be wise recommendations for land managers to control soil incision and support vegetation growth at the andesite post-mining area. © 2022 Uniao Brasileira de Geomorfologia.
