Abstract

Flood disasters, stemming from both natural and human factors, present a significant threat to communities. Consider the case of Rapak Dalam Subdistrict in Samarinda City, where rapid development and improper land use have led to devastating flooding. The transformation of natural landscapes into residential areas, along with land excavation and mining, has disrupted the area's natural functions, resulting in increased runoff. In addition to human factors, natural elements such as rainfall and the lowland topography contribute to the frequent flooding. In 2018, a major flood forced around 10,000 people to evacuate due to prolonged rainfall, highlighting the urgent need for effective mitigation strategies. The overburdened Rapak Dalam Watershed was unable to contain the runoff, resulting in widespread devastation. Despite less intense rainfall, the frequency of flood incidents has risen, making it crucial to address these issues amidst ongoing land-use changes. To combat these challenges, hydrological modeling is essential in predicting and managing flood events caused by land-use changes. By calculating flood discharge, this approach enables the development of optimal mitigation strategies. It is imperative to take decisive action in the face of these escalating flood risks to safeguard communities and ensure sustainable development.

Abstract

North Balikpapan District faces significant challenges in housing planning due to population growth and the announcement of the new capital city (IKN) development in East Kalimantan. Achieving optimal housing provision requires synchronization between community preferences and stakeholder perceptions. This study aims to identify the priority gaps between both parties in housing selection. The Analytical Hierarchy Process (AHP) method was used to analyze community preferences, and interviews were conducted with four key stakeholders: the government, subsidized housing developers, commercial housing developers, and the housing developer association. Secondary data were sourced from a previous study that involved a community questionnaire. The results reveal significant differences in priorities: the community prioritizes availability of facilities and infrastructure, accessibility, and environmental comfort, while stakeholders emphasize financing and house design and quality. These misalignments may affect community satisfaction regarding their living environment and access to public facilities. The implications of this study highlight the importance of policy synchronization between the government and developers to bridge this gap, ensuring more inclusive and sustainable housing development in line with the evolving needs of the community. The model derived from this study can be applied to regions experiencing rapid growth, where the majority of the population is of productive age and falls into the middle-income category, to better meet the needs of the growing population.
