Abstract

This study investigates the alignment between current land use and the official spatial pattern plan (RTRW) of South Lampung Regency, concentrating on Kalianda District, a region characterized by significant economic activity and environmental sensitivity. The study addresses the deficiency in empirical assessments of land use compliance in coastal areas susceptible to land conversion and disaster risks. A Geographic Information System (GIS)-based overlay analysis was applied to compare 2024 satellite-derived land use maps with the RTRW 2011–2031 spatial pattern. The results show that 75.99% (13,301.57 ha) of the district follows the spatial plan, while 24.01% (4,202.65 ha) does not. The biggest difference is that dryland agriculture has been turned into paddy fields, which make up 1,538.17 ha (8.79%). These mismatches are driven by population growth, economic expansion, and limited public awareness of spatial policy. The study contributes to urban and regional planning by demonstrating the need for adaptive RTRW revisions, integrated spatial monitoring systems, and participatory governance to balance development with environmental protection. Findings provide practical input for policy refinement, particularly in aligning spatial plans with dynamic socio-economic and environmental realities.

Abstract

Water is a natural resource that has a vital role and function to fulfill the basic needs of all living things, especially humans, which need to be maintained. Korpri Jaya Village, Sukarame Sub-District, Bandar Lampung City is an area affected by the development of higher education institutions, namely UIN Raden Intan and the Sumatra Institute of Technology, which is characterized by a growing population and housing needs. There is a potential imbalance between water demand and water availability. Water demand is increasing due to population growth, while water availability is decreasing due to changes in land use and a lack of green open spaces. Even Bandar Lampung City has been identified as being in a state of water deficit based on the Strategic Environmental Assessment (KLHS). Therefore, it is necessary to identify the carrying capacity of water in Korpri Jaya Village. The analysis methods used in this study include a grid system approach and calculations of the environmental service index (IJLH) for water providers, which refer to surface water discharge to determine water carrying capacity. The results showed that Korpri Jaya Village has a water carrying capacity of 465,467 m³/year. Water carrying capacity is used as a reference point in spatial planning to anticipate potential water deficits in the future, along with increasing population and land use changes.

Abstract

This study examines land-use suitability and tsunami disaster mitigation in Rajabasa District, one of the areas most severely affected by the 2018 Sunda Strait tsunami. Indonesia’s high coastal disaster exposure underscores the urgency of integrating spatial planning with risk reduction. Using a quantitative-descriptive spatial approach, this research assesses the conformity between existing land use and the spatial allocation defined in the Regional Spatial Plan (RTRW) of South Lampung Regency. Land-use mapping, RTRW extraction, and spatial overlay were conducted using QGIS, complemented by field observations of evacuation routes, signage, assembly points, and coastal protection structures. Results indicate that 74.77% (3,998.50 ha) of land use aligns with RTRW, while 25.23% (1,349.38 ha) shows nonconformity, mainly due to changes in agricultural and forest areas. In terms of tsunami mitigation, Rajabasa has breakwaters, evacuation paths, and temporary assembly points; however, the distribution remains uneven and no vertical evacuation shelters exist. A 1,300-meter buffer analysis reveals that several settlements lie outside effective evacuation coverage. All analytical outputs were integrated into an interactive WebGIS platform developed using QGIS, qgis2web, GitHub, and Netlify. This platform enhances data transparency and supports evidence-based decision-making related to land suitability, hazard exposure, and mitigation infrastructure. The study concludes that strengthening spatial-plan enforcement, improving mitigation facilities, and enhancing community preparedness are essential for building coastal resilience aligned with disaster risk reduction principles and the Sustainable Development Goals.
