**4.1 Redesign**

Variants of problems must be handled through logical steps to solve a problem in terminology as an Algorithm, can no longer be solved with classical patterns, currently the world is faced with very fast changes accompanied by speed, humans must be able to adapt by making transformations, including patterns business carried out

by the bottom line of society to be able to take advantage of and enter into a digital ecosystem that aims to encourage the use of digitalization, considering that the world is currently borderless and is in a digital transformation phase.

Digital transformation requires the speed of adaptation of business actors in coastal areas in facing increasingly bigger challenges with programs that are structured to encourage human resource capacity building. , no function is disturbed, blood circulation pumped by the heart radiates to all organs. Economic activity through business processes (production – distribution – consumption) is born through a complete agile process within an institutional framework that promotes a series of collegial-based work practices, which are loaded with the value of awareness to be agile which really needs a change in mindset and behavior that need to be applied in carrying out an activity or work.

The concept of business development in the rural sector in coastal areas with logical steps is actually to give birth to a form of ultra-micro-industry-based business with optimization of the use or utilization of local resources supported by environmentally friendly production technology by prioritizing local knowledge supported by awareness as a fundamental thing, and that what can change life is the best effort, as Islam says "Indeed, God does not change the state of things so that they change the circumstances that exist in themselves."

The strategy that must be built in the rural sector is to develop the Ultra Micro Business Algorithm business, where the business is built with a sequence of operations that are arranged logically and systematically to solve one problem to produce a certain output and have analytical skills so that the business system includes the availability of modern traditional markets (not eliminating the traditional side) but puts forward the modern side.

The government, especially local governments, must have the courage to carry out a review of the existing planning of coastal areas through spatial planning and environmental protection efforts, including local economic development strategies from various sub-sectors that support community income and contribute to the income obtained by the region, therefore to anticipate the occurrence of problems that not only affect the form and function but must maintain interconnectiveness between land and ocean areas.

Talking about the methodological approach to building a grand design is to organize coastal areas that must pay attention to biophysical or ecological-based, industrial settlement development, tourism and must prepare appropriate community development programs with new strategies due to environmental changes. , because coastal areas in tropical areas such as in Indonesia are ecological and economic assets and store a lot of very high history and culture, but are prone to disturbances both received through natural and man-made changes.

### **5. Power of community**

Knowledge and wisdom grows unbalanced and very selective, not evenly distributed between communities and between nations, so it is important to respond to the crisis by redesigning society for the future.

In his book [13] "Social Sustainability, Past and Future: Undoing Unintended Consequences for the Earth's Survival," calls the six points of "odd" perceptions that shape sustainability. Its complexity is also the cause of single sciences failing to understand the phenomenon, among others, due to "the curse of dimensionality."

The realization that science is only a perception of facts and not fact itself requires a reinterpretation of what is called right or wrong. Transdisciplinarity can be the path to that reinterpretation. But transdisciplinary developments have also faltered, for example, by the question of "intellectual fusion." The ability to think plurally and the result of a comfortable institutional grip on the view of one's own knowledge. Symbiotic is the process of giving and accepting each other to the existence of ideas, beliefs, or other physical cultures that occur between two or more societies to encourage the occurrence of convergence as one of the conditions of the concentrated meeting point.

Communities are not only being fed with various forms of loans by financial institutions, because the main thing is the Government's inclusion program in the form of infrastructure provision including the provision of equipment with various training supports, loans are the last option, it can also be through the development of information systems, developing management and supervision plans, strengthening institutions with disaster management programs, coastal area plans and management, and education, including adaptation to climate change.

The main problems faced by coastal communities are poverty levels, damage to coastal resources, low independence of village social organizations, as well as lack of infrastructure and environmental health in settlements, The COVID-19 pandemic has increased the unemployment rate, which ultimately increases pressure on natural resources (extractive activities) and anthropogenic pressures and thus exacerbates the impacts of climate change.

Government policy greatly affects the balance of implementation of regional development programs that must pay attention to social, economic, and environmental aspects in the aim of minimizing negative impacts so that the landscape planning approach, how development strategies and outputs and outcomes with alternative scenarios are fundamental in the development and utilization of coastal areas that contribute to rural communities, especially fishing communities, availability of fishing areas, recreational and tourist areas including infrastructure including fishing ports, fish auction sites which is a place for fisherman sell their catch from the sea.

#### **5.1 Integrated coastal management**

There are principles in the management of coastal and marine areas. As stipulated in Agenda 21 Chapter 17 Program (a), the Government of Indonesia in 1995 has prepared Agenda 21-Indonesia, and in Chapter 18 on Integrated Management of Coastal and Marine Areas. It is stated that the development orientation and management of coastal and marine areas is a development priority, especially those that include the aspects of integration and institutional authority, so it is hoped that the resources in this region can become superior products in the development of the Indonesian nation in the next century, including conservation areas with 3 (three) categories, namely Parks, Sanctuaries, and Maritime Conservation Areas. The designation of marine conservation areas with the category of parks is carried out for the purpose of protecting, preserving, and utilizing biodiversity or fish resources4 .

Managed conservation areas will be able to have an impact on the economy of coastal areas through fisheries management, tourism, protection of nutfah plasma parts of plants, animals, and microorganisms that have the function and ability to pass on properties, in addition to being useful for assembling superior varieties of a species so that they can be susceptible to disease or have high productivity and will be able to pass on the quality of traits from generation to generation.

The other sides is an important things to do is should focus on coastal areas with the availability of waste management including landfills, pollution strategies that will occur in coastal areas, avoiding the construction of buildings that are not too close to the coastal.

#### **5.2 Social networks analysis**

Strategy in facing the challenges of economic development for coastal communities is important for academia to exist as a problem solver in solving governmentowned problems and to approach with social network techniques, coastal area planning involves multi-stakeholders through a community-based approach strategy, the important role of multi-stakeholders in the preparation of coastal area management plans with various issues and challenges and affected by the dark period for the past two years of the pandemic of Covid 19.

The issue of coastal management through a triangle approach (three lines of defense) by social networks analysis is related to the role of a special envoy in managing a thriving and sustainable ecosystem.

Kazienko et al., [14] said that a social network is a description of connectivity between individuals (actors) and groups, which is illustrated by a point connected to links (ties) (**Figure 5**).

**Figure 5.** *Social network scheme.*

Based on the SNA model, which is often used in measuring a relationship and describing some information, it is defined as a description of the interactions and relationships that always occurs between one another in an organization or work environment and company, the form of this interaction can vary, according to the concept and results to be achieved.

Academia exists in society as a problem solver, namely providing consulting services to the object of the problems encountered, academics act as a driver and become a facilitator who connects various actors in searching for issues and phenomena and returns by providing solutions in terms of answering problems, especially in coastal areas. It is a paradox if there is a diction that says that there is poverty in areas of material surplus of natural resources or biodiversity, but the fact that cannot be avoided is structural and cultural poverty. Nurmalasari (2013) in [15] defines community-based management can be carried out in two ways, namely structural and subjective approaches, and institutional approaches through the human aspects.
