Abstract: Fulfillment of fish demand in the world is generally obtained by capturing fish in the sea or on land, as well
as fish farming (aquaculture). Recently, fish production using aquaculture cultivation has rapidly increased
either on land or inshore and been expected to be able to exceed the amount of capture fish production in the
future. This will become a great potential that should be developed in Indonesia, as an archipelago.
However, offshore aquaculture in Indonesia is kind of new and becomes a pilot project adopted from a
similar program carried out by Norway. To identify the readiness of this program becoming sustainable to
be applied on the south coast of Malang, there is a need to research and conduct social mapping in order to
view and analyze socio-culture, economy, environment aspects linking with community engagement. Social
mapping is conducted qualitatively and quantitatively by collecting and analyzing demographic, geographic,
sociological data, then transferring into the framework and conceptual model. The framework of social
mapping will become an input for a sustainable community-based offshore-aquaculture model, which can
be simulated to forecast how sustainable the program is in the future.
1 INTRODUCTION
Aquaculture or fish cultivation is specifically
defined according to the law of the Republic of
Indonesia No. 31 of 2004 as an activity to maintain,
to grow, and/or to breed fish and to harvest the
results in a controlled environment, including
activities that use ships to load, transport, store, cool,
handle, process and/or preserve it. Aquaculture
cultivation continues to develop rapidly and is
widely carried out in open waters, such as rivers,
reservoirs, lakes, and coasts. Aquaculture has
increased and is very important in recent decades
throughout the world due to the escalation of
demand for fish and stagnation in capture fishery
supply (FAO, 2013). In the next few years, demand
for fishery products in developing countries is
estimated to rise because people are encouraged to
adopt healthier diets and to have the mindset that
fishery products are as healthy foods. For capture
fisheries, China was quantitatively the top-ranking
fishing country followed by Indonesia, India, the
United States of America, and the Russian
Federation. Nineteen countries caught more than one
million tonnes each for fishery products in 2017,
calculating for more than 72% of global catches. On
the other hand, fishery production from aquaculture
in the world has increased steadily to an average of
4.8% during 2011-2017 (FAO, 2019).
Additionally, as aquaculture cultivation
gradually develops, the need for suitable space in
fish farming has been followed by the development
of a sustainable, cost-efficient, and effective
environmental methodology as well as offshore
aquaculture (Maricchiolo et al., 2011). There are
also possibilities that bound the expansion on land
and inshore coastal areas, and improvement of
operational technology in fish farming studies, have
led to broadening the worldwide interest of offshore
aquaculture (Ferreira et al., 2012). Offshore
aquaculture has some great advantages over inshore
aquaculture, such as to prevent possible conflicts
between environmental effects in coastal areas and
commercial aquaculture technology (Benetti et al.,
2010), to allow a wide and rapid dispersal of
dissolved waste products as well as the higher flush

impact in open water (Holmer, 2010; Troell et al,
2009), and to reduce associated benthic stress and
local pollution (Naylor and Burke, 2005). Therefore,
it seems that offshore aquaculture will be the
solution for increasing seafood demand (Wheeler,
2013).
However, the aquaculture cultivation system is
strongly interrelated to three aspects of
sustainability: its technology, socio-economic, and
environmental and climate changes (Trapani et al.,
2014). There are some potential risks, such as few
conflicts between offshore aquaculture and its
activities in regards to recreation, tourism, or coastal
esthetics (Teitelbaum, 2011). Moreover, some
challenges of aquaculture are related to socio-
economic issues and ecological impacts (Suryanata
and Umemoto, 2005) as well as the optimal siting,
which is a trade-off between factors, such as depth
and distance to port (Kapetsky et al., 2013). In order
to know further these challenges, there are some
research which overcome that challenges, such as
the perceived impact of this aquaculture area on
small-scale fisheries had been researched using
Fuzzy Logic model (Ramos et al., 2015) and using
Bayesian approach regarding stakeholder’s
conceptualization (Ramos et al., 2017), integrated
modeling approach in providing the effects of both
inshore and offshore aquaculture production and
environment in a coast (Ferreira et al., 2014), as well
as stakeholder-driven future scenarios for offshore
aquaculture development & potential effects on
fishermen (Tiller et al., 2013).
In Indonesia, the successful development of the
aquaculture cultivation has also been proven to play
an important role in increasing national fish
production. Aquaculture has some positive impacts
which are environmentally friendly and more
sustainable. Thus, aquaculture cultivation is needed
to meet the national fish consumption needs that
increase annually. Besides that, this aquaculture
method provides a multiplier effect on employment,
both directly and indirectly, and from upstream to
downstream. Indonesia’s fishery production from
aquaculture had gradually reached a 16% average
increase during 2006-2016 (BPS, 2019). This
certainly illustrates that national fishery production
with aquaculture is in great demand in almost all
parts of Indonesia. Fish farming using aquaculture is
not a new thing for Indonesian people, especially for
inland aquaculture, and more recently is inshore
aquaculture. Nevertheless, fish farming using the
offshore aquaculture method is very new, and the
Ministry of Maritime Affairs and Fisheries of
Republic of Indonesia made a breakthrough to
conduct a pilot project of three Offshore
Aquaculture units in 2018.
Furthermore, according to the determined
research object on the south coast of Malang, East
Java Province, even though there was a significant
decrease in 2016, aquaculture production had risen
to 57% of the average increase during 2011 2015
(BPS, 2019). This definitely raises questions related
to the decline in aquaculture production in East Java.
In addition to that, fish farming using the onshore
aquaculture in East Java only produced 271 tons in
2017 (BPS, 2019). The value of production in East
Java was relatively small compared to other
provinces in Indonesia, such as Kep. Riau, North
Sumatra, Maluku, and North Sulawesi, which were
ranked top in the national fisheries production using
aquaculture.
Driven to the aforementioned concerns,
observations have been made on the South Coast of
Malang. Based on observations that have been
carried out for fishermen in 2018, it can be
concluded that the fishermen's knowledge is very
poor regarding aquaculture cultivation, especially
offshore aquaculture. With the existence of offshore
aquaculture, it will give some positive impacts, such
as the community can work for hatcheries, fish
farming, loading and unloading workers,
transportation workers, harvest workers, to offshore
aquaculture stall owners. The fisheries sector plays
an important role in Indonesia's economy through
the supply of fishery animal proteins, livelihood
diversification, revenue generation, and foreign
exchange earnings (Tran et al., 2017).
Therefore, it is very necessary to increase
fishermen's knowledge in the form of training and
assistance on the management of aquaculture
operations, especially offshore aquaculture for
fishermen in the South Coast of Malang, especially
Sidoasri Villagers, and surrounding areas. To
achieve the success of this pilot project of offshore
aquaculture, a social mapping study is needed to
observe the community of Sidoasri Village and
surrounding areas. This study aims to provide a
comprehensive picture of Sidoasri Village and its
community in the form of both potential and
challenges. This social mapping can be conducted in
identifying the form of mapped locations, including
actors who play a role in the process of social
relations, social networks, strengths, and interests of
each actor in community life, especially in
improvement of people's living conditions, existing
social problems including the presence of vulnerable
groups, and the available potential, both natural,
human, financial, infrastructure as well as social

capital. Furthermore, another aim of this social
mapping is to identify the readiness of offshore
aquaculture becoming more sustainable to be
applied based on the community in the South Coast
of Malang.
2 METHODOLOGY
The methodology of this research combined social
mapping activities and System Dynamics modeling.
The main research stage of this study is mainly
carried out with two stages: (1) preliminary studies
of the research area in the case study in order to
draw a framework of social mapping and (2)
developing the System Dynamics model using
Causal Loop Diagram as a mental and conceptual
model. In attaining the research objectives, this
study shows the existing condition of the system
observed and combines the framework with the
Causal Loop Diagram, then to perform
interdependencies within variables and to show the
closed feedback loops formed by variables
relationships (Vanany et al., 2019). Firstly, we
gathered secondary data and did visualization using
a geographic map. Secondly, modeling sustainable
community based offshore aquaculture using System
Dynamics approach was conducted. Before
conducting the main research stage, the
understanding of the study area as a research object,
and how data to be gathered should be accompanied.
The following below is the description of the
preliminary studies of the area.
Moreover, relevant data were gathered from two
types of data sources, such as primary data
conducting direct observation, including in-depth
interviews and surveys with relevant stakeholders as
well as secondary data –using literature review (BPS
reports and some journals & articles). The
stakeholders analyzed in this study were selected by
the recommendation of the previous study in the
same area through Enabling Community Action
(ENACT) (Riniwati et al., 2014). These collected
data were identified and were processed then in
order to get the relevant variables in the observed
system within the chosen variables. It is essential to
conduct in order to build the conceptual model.
Nonetheless, some corrections of the model were
often conducted in creating model conceptual until
the model was assuredly valid and representative.
The validation method was performed by using
Boundary Adequacy Test and Structure Verification
Test (Barlas, 1996). Boundary Adequacy Test takes
into account key structural relationships, which are
significantly necessary to fulfill the model’s
objectives. In addition to that, the Structure
Verification Test was carried out by directly
checking and ensuring model structures with the real
system structure.
2.1 Preliminary Study of Area
In the first stage, conducting a preliminary study of
the research area is needed. The area observed in
this study is exactly Perawan Beach, in the South
Coast of Malang. Perawan Beach is administratively
located in Sidoasri Village, Sumbermanjing Wetan
District, Malang Regency (Figure 1). This village is
the result of the division of Tambakasri Village and
is about 60 km to the south of Malang City (see
Figure 1). The beach is still very beautiful, not yet
widely known, even by the majority of Malang
residents themselves. Since this beach has not been
managed as a tourist attraction, so it is still very rare
to know the existence of the beach. This is very
different from Sendang Biru Beach, which is a
Fishery Port or Tiga Warna Beach, which is already
well-known by the community as a tourism
destination. Some people call this beach as Sidoasri
Beach because it is located in Sidoasri Village or
Tambakasri Beach because it used to be in the
Tambakasri Village area. Therefore, Perawan Beach
has a great potential to be developed more in terms
or offshore aquaculture, which will deliver positive
impacts for tourism, economy, and socio-culture of
villagers.

Malang (source: google map)
Besides that, from the topography point of view,
Sidoasri Village is in the form of lowlands, which is
around 0-100 meters above sea level with a slope of
15o and has fertile brown soil for agricultural land.
This village has some land with different functions,
such as forest (mangrove around the shore), paddy

152
fields, plantation, settlements, and fishpond which
are respectively 60%, 16%, 12%, 11%, and 1% of
total land (BPS of Malang Regency, 2018). Due to
its geography and topography condition, the
profession of the villagers is highly dominated by
farmers in a paddy field or plantation, and some of
them as fishermen with small proportions. However,
many villagers have multiple professions, which
means that they will be farmers while the harvest
time comes. Otherwise, while the weather is suitable
for sailing, then they will be fishermen in order to
generate revenue for their lives. Based on
demography, the total number of Sidoasri Villagers
is around 5000 people who are divided into the same
proportion of gender, with 50% of women and 50%
of men. Regarding the main natural resource
products of Sidoasri, there are various fish products,
such as lobsters, shrimps, squids, kerapu fish,
stingray, and other types of fish as well as
agricultural products, such as paddy, coffee, banana,
and cloves.
3 DISCUSSION
In this part, there will be sub-topics that will be
discussed regarding the objective of the study, which
is to create a social mapping framework for
sustainable community based offshore aquaculture
and to model this aquaculture in terms of a
conceptual model.
3.1 Framework of Social Mapping
Social mapping aims to provide a comprehensive
picture of mapped locations, including actors who
play a role in the process of social relations, social
networks, the strengths and interests of each actor in
community life, especially in improving people's
living conditions, existing social problems including
the presence of vulnerable groups, and available
potential, both natural, human, financial, and
infrastructure as well as social capital.
Based on this study, the following data will be
obtained, such as:
1) Village profiles which includes: (a)
Demographics, statistics on population composition
(sex, employment, poverty level, education level,
welfare level, etc.), (b) Socio-economic, cultural,
community norms and values, community structure,
social relations, social mobility, community
leadership, customs and habits, (c) Geographic,
including location of the community, location of
facilities, access roads, land use, and other
geographical aspects.
2) The mapping of social networks includes
Relations between actors (stakeholders), both
individuals and institutions, and the nature of the
relationship. Forums that are used by the community
to discuss public interests. Potential in the
community which may be developed: natural
potential, human resource potential, financial
potential, physical/infrastructure potential, and
social capital potential. In this study, there are some
stakeholders involved, namely village government
(Village Council-BPD, Village Community
Empowerment Organization-LPMD, Family
Welfare Programme-PKK), fishermen and farmers
community, youth organization (Karang Taruna),
church and mosque community, saving and loan
cooperatives, Fostering Community Monitoring
Group (POKMASWAS), and Women’s cooperative
(KOPWAN). These stakeholders provide close
engagement with the villagers and social networks
among them.
3) Social problems which become obstacles or
often arise so that they become obstacles to the
development of society.
Furthermore, the social mapping framework had
been designed in order to enable and to facilitate the
overall mapping activities in the observed
community in regard to operating sustainable
offshore aquaculture. This framework can be seen in
Figure 2.

Malang, Indonesia

community engagement.
3.2 Conceptual Model of System
Dynamics
In the second stage, system modeling related to the
research object is conducted to comprehend the key
leverage elements that contributed to system
improvement. Furthermore, understanding the
elements of the system can be performed by
firsthand identifying relevant variables related to the
community based offshore aquaculture system in
Indonesia generally and in the South Coast of
Malang particularly. Afterward, a system dynamics
model is conceptually created using a conceptual
model based on the social mapping results of
offshore aquaculture cultivation for the community.
This mapping framework is used to understand in
identifying the main variables in the system easily.
A model represents the basis of experimental
investigations, which has some advantages, such as
relatively inexpensive and time-efficient rather than
conducting an experiment in a real system
(Forrester, 1968). In this case, the conceptual model
of sustainable community based offshore
aquaculture was designed using a causal loops
diagram (CLD).
In addition to that, the causal loops diagram is
essentially built to correlate the main variables that
will be depicted in the model. By using causal loops,
it is able to easily understand the causal relationship
between variables and how far the influence of
variables on system behavior is as well as how the
impacts of each variable to the others area (Sterman,
2000), such as community-based mangrove
cultivation policy (Maftuhah, 2013). In developing
the system dynamics model, there are some elements
of the causal loop diagram, which are represented as
a set of variables, arrows/links, feedback, and
feedback loops. The variables of CLD indicate
sequences of cause and effect, as well as arrows,
represent which variables affect other variables.
Moreover, feedbacks indicate positive/negative
polarity of the influential relationships, as well as the
feedback loops, represent loop types (both in the
clockwise direction) - reinforcing loop (R) and
balancing loop (B).

Furthermore, reinforcing loops (R) can be
defined as a positive loop; otherwise, balancing loop
(B) is a negative loop. Each identified variable in the
proposed system dynamic model was defined. The
model of the system was divided into five sub-
systems, namely socio-culture, offshore–aquaculture
cultivation, economy and infrastructure,
environment, tourism impact, and stakeholders,
which can be seen in Figure 3. Then, the main
variables within sub-systems were identified for
each variable.

4 CONCLUSIONS
In general, the aims of the study had been achieved
in order to make a social mapping framework as an
input for modeling sustainable community based
offshore aquaculture in Perawan Beach, South Coast
of Malang. In doing social mapping study,
preparation of survey had also been conducted by
making questionnaires which involves sustainability
aspects, demography, and etc. These questionnaires
were distributed to many respondents of villagers as
samples, and afterward, the results were processed
using statistical analysis. This survey was confirmed
with Focus Group Discussion as feedback of survey
results. The analysis of survey and Focus Group
Discussion shows many critical and potential
variables which can be encouraged into better
condition, such as villager's perceptiveness of
offshore aquaculture, economic and environmental
aspects, socio-cultural aspect, and stakeholders
involvement which provide social engagement
among villagers and them. The result of social
mapping is essential for modeling input and
completely depends on the direct observation and
social network analysis, which has been described in
the discussion.
Furthermore, the conceptual model of this study
had been created, as well. This model is derived
from the results of the social mapping framework
with Causal Loop Diagram's rule. Regarding the
next research, this conceptual model is for input to
do further analysis, such as creating a simulation
model and determining the best policy scenarios. By
the time the simulation model has been created,
there will be a prediction of preparedness of
community in implementing offshore aquaculture in
