One of the areas that are planning and developing this public space is the Ulee Lheue Beach area. This can be seen from the infrastructure development that the government is trying to make use of the area. This study aims to see the conceptual success of the use of regional space. This research uses the descriptive quantitative deductive method. The scope location of the research object is the Ulee Lheue seaside area. The data obtained for research are questionnaires, interviews, and secondary data. The sample used in this research is a proportional random sampling method. The principle of coastal urban planning is the basis for urban or regional planning, which includes various considerations and planning components for the success of a good city or region. The principle regarding the concept of a recreational waterfront area by the beach of Ulee Lheue which is very successful relates to the interest of the people of Banda Aceh City towards the area by the beach of Ulee Lheue, namely the uniqueness of the area. And what works relates to natural resources, in the form of water quality in the area. While those that are not successful relate to inter-regional integrity within the area.

Small island regions are facing disaster risks due to their exposure to various hazards, e.g. floods, landslide, and earthquake. In order to achieve long-term disaster resilience, one of the significant strategies is applying spatial planning based on disaster risk reduction. Methods for multi-hazard risk assessment and risk analysis have been broadly discussed, nevertheless, its implementation in spatial planning is inadequate. In this study, we conducted a multi-hazard risk mapping of Sangihe Island and reviewed its spatial plan. It is identified that disaster risk analysis hardly meets its standard in consequence of insufficient secondary data availability. Also, the spatial plan merely utilizes hazard maps for consideration, not yet as risk analysis, resulting in allocating vital elements in high-risk areas. Hence, secondary data support is necessary for accordance with the needs of standardized risk analysis and is updated regularly. Furthermore, integration of risk analysis into spatial planning is required to determine the direction of development, which not only reduces exposure to hazards but emphasizes more towards the capacity building to reduce vulnerability.

Riverside landscape design is developed not only to enhance amenity but also to address disaster risks. This study aims to estimate the value of the design of the riverside landscape, in terms of amenity and disaster mitigation. Contingent valuation method (CVM) is used for the valuation of the proposed design of the riverside landscape. The case study was taken place in Yogyakarta City, Indonesia, that has three main rivers flowing through the city; Winongo River, Code River, and Gajahwong River. As the rivers are headed from Merapi volcano, the community that occupied the riverside areas is threatened by the risks of cold pyroclastic debris flow, besides the regular riverine flood. Respondents are family representatives that chosen randomly from the total population of Yogyakarta City. There are 580 samples, consists of 333 samples of Type A and 247 samples of Type B. Visual image with an explanation of amenity obtained higher WTP rather than with explanation of disaster mitigation indicates that the explanation of amenity features of the design is valued higher rather than disaster mitigation features. In addition, the value of extrapolated WTP results in a considerable amount in a monetary term that represents the cost of realization of the design and also serves as the feasibility of the project. However, the visual image contains a mixed value of the design to some extends, and the explanation increases the value of the design, due to the respondents may grasp other aspects than explained by viewing the visual image of the design. Reasons for willing to pay are all positively related to WTP, implies that people behave towards the riverside area is influencing the value, specifically related to their financial state. CVM as a valuation technique for the public good can be used to understand the perception and also to measure the acceptance of the public towards the proposed design.
