Waterfront Public Space Planning on Krueng Aceh River in Banda Aceh-Indonesia

Urban waterfront development had been a global trend in many cities around the world, not only in big cities but also in medium-sized cities, and even small towns. They have improved their waterfront area with good utilization in order to create attractive public spaces. Located on the most western tip of Sumatera Island in Indonesia, the riverbank area along Krueng Aceh River in Banda Aceh is undergoing to waterfront oriented and has enormous potential to be developed as waterfront public space. But in its implementation, there is still less waterfront utilization so which affects the lack of urban public space quality improvement along the riverbank. This paper presents the waterfront planning on Krueng Aceh River in Banda Aceh, Indonesia, and provides a strategic plan as a new waterfront concept in terms of urban public space quality improvement that can be applied immediately.


Introduction
Waterfront has an important role for the people live and it will be continuous all the time. Urban waterfront development had been a global trend in many cities around the world, not only in big cities but also in medium-sized cities, and even small towns, they have begun to develop their waterfronts into open public spaces in order to improve urban space quality. As stated by Erkök (2009), many cities around the world are creating ambitious waterfront projects, trying to solve their problems related to environmental preservation and combining them with improved public spaces.
London's waterfront has transformed from exploited river that people used for trade through water and not livable into first class waterfront where people enjoy life and created a great dockland which is the largest port in the world (Global Waterfront Talk, 2016). In Australia, Sydney's Darling Harbor has been transformed from the once derelict docklands into a city display and tourism center, and the urban waterfront in Melbourne has been redeveloping to represent the city's globally oriented, economically focused, consumption-based urban strategy (Davidson, 2009). By faced urban problems from declining of industrial area, emerging of slum area and environmental problems, Zanzibar's Stone Town waterfront in Tanzania was given spatial restructuring included the relocation of port industry, preservation of ferry and passenger facilities, opening public spaces and retail facilities, reintegration and restoration of the Culture Center (Pramesti, 2017).
Waterfront development provides various opportunities such as sustainable development, ecological environment, and ecosystem protection. Urban waterfronts can help restore or enhance the vitality of urban developments, improve local environments, seize development opportunities, and reshape regional characteristics and image (Wu et al., 2019). By good utilization of waterfront area in urban space, the city and its people can achieve some advantages such as aesthetic image and recreational opportunities, better community life, improved public space, increased land values and supported economic development. As stated by Breen et al. (1994), the need to improve environmental quality, the availability of abandoned waterfront sites, the pressure upon urban space and infrastructure brought about by urbanization have led the waterfront redevelopment as a fitting solution (Pramesti, 2017).
For example, Shanghai is one of big cities in the world and one of famous cities in China that has an excellent waterfront development along Huangpu River. The river has changed dramatically and grew into a waterfront that is parallel to some famous global waterfronts around the world. Through urban regeneration, from the largest China's riverside industrial development, Huangpu Riverside has transferred from industrial basis of shipping and manufacturing to a place with finance, trade, and tourism at the core of its development. The river affords its high quality improvement waterfront urban spaces under the theme of innovation expo, culture experience and ecological entertainment. Transformation of waterfront space in Shanghai points out that the urban waterfronts with geographical advantages and historical values have the potential to provide a powerful impetus to the economic and social development of the city (Chen, 2009).
Located on the most western tip of Sumatera Island in Indonesia, the riverbank area along Krueng Aceh River in Banda Aceh is undergoing to waterfront oriented and has enormous potential to be developed as waterfront public space.
But in its implementation, there is still less waterfront utilization such as inactive and abandoned area, rarely visited by local community, no greenway, and less planning strategy is expected to be able to give effort reflecting city's identity of Banda Aceh, although it is not a popular city but its waterfront have own characteristics as well as big cities.

The Beginning of Waterfront Planning on Krueng Aceh River
Banda Aceh is located on the most western tip of Sumatra Island in Indonesia.
Geographically Krueng Aceh River is one of the rivers in Aceh Province which has approximately 145 km length and several tributaries flow into the river body. The beginning of waterfront planning along Kreung Aceh River in Banda Aceh was carried out in 1990s, when the river is still used as landfill. At that time, the Government of Banda Aceh under Public Works and Spatial Planning Agency began to work on developing the riverbank area. Hence, there has been made some planning for waterfront development continuously until now. With the ability of the budget, the riverbank area of Krueng Aceh River is slowly already organized, start not backing up, and aware of the river environment.
In 26th December 2004, Indian Ocean Earthquake and Tsunami disaster occurred and destroyed most part of Banda Aceh. The coastal area at the river mouth was one of the worst affected areas that many buildings, social-economic facilities, urban utility, and transportation route completely destroyed to the ground, besides around 70.000 fatalities. Krueng Aceh River was also affected by the disaster that swept water up some 40 km of the river. After disaster, government endeavour to rebuild some urban facilities and utilities in order to rehabilitation and redevelopment especially in the worst affected area. Literally, the development of both riverbanks along Krueng Aceh River is included the first priority in the implementation of strategic area as waterfront development.

The Potential of Krueng Aceh River as Waterfront Public Space
The riverbank area along Krueng Aceh River in Banda Aceh has enormous potential to be developed as waterfront public space. The potentials are highlighted 2) The role of protected and strategic area Krueng Aceh River has two important roles at once, based on the policy and development strategy of urban space pattern of Banda Aceh, Krueng Aceh River is included into two categories at once (Figure 1). 1) Protected area aims to provide protection against environmental sustainability that includes natural resources and artificial resources, to maintain water supply (hydrological function), and is expected to preserve the macro climate environment (Ministry of Public Works and People's Housing of Indonesia, 2011). The river is strived for maintaining environmental protection in term of urban sustainable development in long-term period. 2) Strategic area aims to develop and to improve urban economic growth that productive, efficient, and able to compete in regional and national level; cultural and historical preservation; and encouragement of new urban development in the future (Government of Banda Aceh City, 2009a).
The river is directed for waterfront revitalization as public space in order to encourage new urban development to improve urban space quality along the riverbank.

4) Islamic City
The waterfront development in Banda Aceh is more preferred in the city center area where is located on Old Town area and closed to Baiturrahman Grand Mosque which is an iconic building and the landmark of Aceh Province. The existence of Baiturrahman Grand Mosque is a city's identity of Islamic City and its function as cultural center with great historical value and has upgraded into religious tourism object.

5) Central Business area
Trade and commercial activities in the city center have grown since the early development of the city during Sultanate era in 13th century so there has high economic value and has economic growth potential. The area also was planned to support urban development of Banda Aceh Central Business (as known as Central Business District) in the future.

Strategic Plan for Waterfront Public Space on Krueng Aceh River
The strategic plan aims to generate new opportunity as a development guided in order to realize urban public space quality improvement on riverside area related to ecology, lifestyle and aesthetic image to maintain river environment, to be better community life, and to encourage recreational opportunities. So that, based on the identified potentials previously, the strategic plan for waterfront's public space of Krueng Aceh River can be generated to be applied as follow:

1) Planning Target
As a historical area of Aceh Sultanate and Islamic civilization center in ancient time, and still played a role in supporting community activities of the city, Krueng Aceh River can be considered to become Aceh Islamic Riverside that can be transformed into an attractive public space as the center of Acehnese Culture, Islamic City, Local Economic Development, and Water Transportation System.

2) Function Layout
According to physical zone division of urban space utilization, strategic area of Banda Aceh, and current situation of Krueng Aceh River, the main area of Krueng Aceh River and its function layout can be identified as shown on Table 1 and Figure 2.

3) Development Concept
In order to improve public space quality, the strategic plan for waterfront space on Krueng Aceh River can be guided by the development concept of "Islamic-based, Cultural-enriched, and River-oriented". It aims to endeavor strengthening the city's identity of Banda Aceh as Islamic City, to highlight the local wisdom of Acehnese Culture, and to realize waterfront public space not only as attractive view of the city but also for public interest to be actively used by citizen. Therefore, the strategic plan for waterfront's public space on Krueng Aceh River can be applied as shown on Table 2.

Cultural-enriched
Aesthetic Image -Realizing the city with a high cultural value.
-Promoting the characteristic of Acehnese Culture to attract visitors and tourists.
Local Product Economic Development -Developing micro economy to increase local community income.
-Supporting craft industry to improve creativity and to enhance business opportunity independently for local community.
-Increasing economic growth from local to global.

River-oriented
Waterfront's Public Space -Arranging a continuous waterfront and connected with urban activities.
-Providing comfortable public space for community activities.
-Easily accessed for people to enjoy the river view.

Attractive Ecological Entertainment
-Creating natural experience to maintain and to preserve environment.
-Encouraging community for walking and cycling on the riverside.
-Bringing up recreational facilities to be used by public.
Water Transportation System -Supporting the water network as a waterway along the river.
-Making a new tourist destination as water tourism in the future.

Conclusion
Based on its role in supporting community activities since the early development of the city and the existence of Baiturrahman Grand Mosque as a landmark of the city, there has great historical value to strengthen the city's identity of Banda Aceh as Islamic City and enriched by the characteristics of Acehnese Culture on to support water transportation system in line with its utilization for Waterfront City (WFC) development and also expected to be a Central Business area in the future. So that, Krueng Aceh River has appropriateness to become an attractive waterfront as public space.
Compiling a comprehensive strategic plan can generate new opportunities as a conceptual urban design in the field that can be discussed for further research.
In the implementation, it may take several years to obtain the successful development of urban waterfront. It needs to learn more from the experienced cities to explore the way of new generation on their waterfront redevelopment. By good improvement on riverside area, it can achieve some advantages such as better river environment, be the center of community activity, natural outdoor leisure and beautiful scenic spot of the city.
