ABSTRACT A major volcanic eruption in May 2006 near a gas drilling site in Sidoarjo,
Indonesia, continued to emit toxic substances, including the dangerous chemical phenol.
Phenols, which are found in oil and gas, pharmaceuticals, paint, and electronics, can cause
human skin, eye, and mucous membrane irritation if exposed. The impact of the Lapindo
mudflow has been detrimental to the economy, society, and ecology, including damage to
agricultural land, disruption of livelihoods, and business closures. This research aims to
identify effective disaster recovery and mitigation strategies in dealing with toxic
mudflows. Authorities have planned to divert mud into the Porong River, convert the
affected area into a tourist attraction, and use control pumps to deal with flooding.
However, the collapse of the mud embankment caused public concern about flooding and
loss of life. This study uses snowball sampling and phenomenology methods, focusing on
residents around the Lapindo embankment area in Gempolsari Village. Data was collected
through interviews, observation, and photo documentation. The research results show the
importance of mitigation strategies that involve village halls to provide information and
build residents' confidence in facing disasters. It is hoped that these findings will provide
insights for the development of more effective disaster mitigation systems.

1. INTRODUCTION
The 2006 Sidoarjo mudflow disaster, commonly
referred to as the Lapindo mudflow, remains one of
Indonesia's most catastrophic environmental crises
(Eggers, 2020; Khalaf & Hamad, 2023; Rubonis, 1991a) .
Originating near a gas drilling site, the eruption has
continued to release toxic substances (Ekawati,
2021; Flanagan, 2020a; Palupi, 2021), including
phenols, which are known for their hazardous
effects on human health and the environment.
Phenols, ubiquitous in various industrial
14

applications such as oil and gas, pharmaceuticals, and
electronics (Hao, 2020a; Ramadan, 2024; Zandalinas,
2021), can cause severe irritation to the skin, eyes,
and mucous membranes upon exposure (Al-Taee &
Kashkooul, 2023). The long-term discharge of these
chemicals has led to significant socio-economic and
ecological damage (Ekawati, 2020; Flanagan, 2020b;
Mujahidin et al., 2023), necessitating comprehensive
disaster recovery and mitigation strategies.
Alhabow / Internal Audit and its role

Empirical studies have documented the extensive
impact of the Lapindo mudflow on the local
economy and society (Hao, 2020b; Nalarsih, 2024).
For example, research conducted by Davies et al.
(2007) highlighted the extensive damage to
agricultural land and the subsequent disruption of
livelihoods. Business closures and the displacement
of communities have further compounded the
economic strain on the region. Additionally,
environmental studies have underscored the
adverse effects on local ecosystems, with significant
alterations in soil composition and water quality
reported by Mazzini et al. (2009).
The Lapindo mudflow disaster, also known as the
LUSI (Lumpur Sidoarjo) mudflow (Hendarto & Hiat,
2024), remains one of Indonesia's most significant
environmental calamities. Despite various efforts
over the past 17 years (Kouadio, 2012; North, 2013;
Whittaker, 2015a), the toxic mudflow continues to
pose severe threats to the local population,
economy, and environment. Previous research has
highlighted multiple challenges in managing such
large-scale disasters, including the complexity of
coordinating effective recovery strategies, the
technical difficulties in controlling the continuous
flow of toxic substances, and the socio-economic
impact on affected communities.
Empirical
evidence
from
earlier
studies
underscores the critical need for innovative and
sustainable disaster recovery and mitigation
strategies (Bonanno, 2010a; Faturechi, 2015;
Whittaker, 2015b). For example, a study by Davies
et al. (2007) illustrated the
long-term
environmental degradation caused by mudflow and
its adverse effects on human health due to
prolonged exposure to hazardous chemicals like
phenol. Additionally, the socio-economic impact, as
documented by Susilo (2010), reveals that
thousands of residents have experienced
displacement, loss of livelihood, and psychological
distress. These findings emphasize the necessity for
comprehensive research that not only addresses
immediate recovery but also ensures long-term
resilience and safety for the affected communities.
The current research aims to bridge these gaps by
focusing on a holistic approach to disaster recovery
and mitigation. By employing snowball sampling
and phenomenology methods, this study delves into
the lived experiences of residents in Gempolsari
Village, an area severely impacted by the Lapindo
mudflow (Bonanno, 2010b; Gabaix, 2012). Data
collection through interviews, observations, and
photo documentation provides a robust framework
for understanding the community's needs and
concerns. This research aspires to offer actionable
insights and recommend effective strategies that

can be implemented by local authorities and
stakeholders to enhance disaster preparedness and
recovery efforts in Indonesia.
Given the complexity and severity of the situation,
this research aims to identify and evaluate effective
disaster recovery and mitigation strategies for
managing toxic mudflows (Nursaid, 2024). Current
efforts by authorities to divert the mud into the
Porong River, transform the affected area into a
tourist attraction, and implement control pumps to
manage flooding have faced considerable challenges,
including the failure of mud embankments, which
heightened public concerns about additional flooding
and potential loss of life. By employing snowball
sampling and phenomenology methods, this study
focuses on the lived experiences of residents in
Gempolsari Village, near the Lapindo embankment.
Data collection through interviews, observations, and
photo documentation aims to provide a nuanced
understanding of the efficacy of current mitigation
strategies and highlight the critical role of community
engagement and information dissemination through
village halls in building resilience against future
disasters.
In conclusion, this research not only aims to offer a
comprehensive analysis of the current disaster
mitigation efforts but also seeks to amplify the voices
of the affected residents, ensuring their experiences
and insights contribute to more effective and
sustainable disaster management strategies. By
emphasizing community engagement and thorough
data collection, the study strives to present a detailed
picture of the challenges and opportunities in
disaster recovery. Ultimately, the goal is to foster a
more resilient and prepared community in
Gempolsari Village and similar areas across
Indonesia, ensuring that future mitigation efforts are
informed by those who have lived through these
devastating events.

2. METHODS
This research employs a mixed-method approach,
integrating both qualitative and quantitative data
collection and analysis techniques. The main
methodologies utilized are snowball sampling and
phenomenology, which are particularly effective in
understanding the lived experiences and perspectives
of the affected community members.

Empirical Evidence from Previous Studies
Previous studies on disaster recovery and mitigation
have highlighted the effectiveness of community
involvement and local knowledge in developing
resilient strategies. For instance, a study by (Gandy,
2008) found that community-based disaster risk
reduction (CBDRR) significantly enhances the capacity
of local communities to manage and mitigate disaster
risks. Similarly, research by Wisner et al. (2012)
emphasized the importance of integrating local
knowledge and practices into formal disaster
management frameworks to ensure sustainability and
effectiveness.
In this research, the use of snowball sampling ensures
that a diverse range of perspectives is captured, while
phenomenology provides a deep understanding of the
individual and collective experiences of affected
residents. The combination of these methods facilitates
a comprehensive analysis of the challenges and
potential solutions for overcoming the toxic mudflow
disaster in Sidoarjo.

significant financial losses for farmers who
depended on their crops for income. Previous
studies, such as those by Sutikno (2008), highlight
that the immediate economic impact included a
sharp decline in agricultural productivity and a
surge in unemployment rates. To counteract these
effects, recovery strategies have been proposed
(Sudiantini et al., 2023), including financial
compensation for affected families and the creation
of alternative employment opportunities through
government-funded programs (Dahliani et al.,
2024). The introduction of microfinance initiatives
LUSI Burst: Overcoming … / Retno Tri Nalarsih

has shown promise in helping local businesses
regain stability and foster economic resilience.
3.1.1 Economic Impact
The LUSI mudflow has rendered thousands of
hectares of fertile land unusable, crippling the
agrarian economy of the region (Sungkawati et al.,
2023). According to a study by Kartomo et al.
(2010), the mudflow displaced over 13,000
families and led to the closure of more than 20
small and medium enterprises (SMEs). This
displacement also caused a significant drop in the
regional GDP, estimated at around 5% in the first
year alone (Sutikno, 2008). The agricultural sector,
which was the backbone of Sidoarjo's economy,
experienced the most severe blow, with rice and
sugarcane plantations being the worst hit.
3.1.2 Recovery Strategies
To mitigate these economic impacts, several
recovery strategies have been implemented and
proposed. One of the primary measures is the
provision of financial compensation to affected
families. A report by the Ministry of Social Affairs
in 2009 indicated that over IDR 1.5 trillion was
allocated for compensation, although the
distribution process faced numerous bureaucratic
hurdles. Additionally, the government introduced
livelihood programs aimed at creating alternative
employment opportunities. For instance, the
"Rebuild Sidoarjo" initiative focused on skill
development and vocational training, enabling
displaced farmers and workers to transition into
new trades.

Impact Category
Agricultural Loss
Business Closures

Comparing the LUSI mudflow disaster recovery with
other international cases provides valuable insights.
In the aftermath of the 2011 Tōhoku earthquake and
tsunami in Japan, the Japanese government
implemented extensive economic recovery plans,
including direct financial aid, tax breaks, and
infrastructure rehabilitation (Mimura et al., 2011).
Similarly, the response to Hurricane Katrina in the
United States involved federal assistance through
the Federal Emergency Management Agency
(FEMA), which focused on rebuilding infrastructure
and providing financial aid to affected businesses
(Baker, 2006).
Empirical evidence supports the efficacy of these
strategies in fostering economic resilience
(Hendarto et al., 2024). A longitudinal study by
Yulianti (2012) on the microfinance initiatives in
Sidoarjo found that small loans significantly helped
local businesses to restart and grow, reducing
unemployment by 15% over two years.
Additionally, the introduction of vocational training
programs has enabled nearly 30% of displaced
workers to secure new jobs in different sectors
(Sugiono, 2011).
In conclusion, effective disaster recovery and
mitigation strategies are crucial for economic
resilience in the face of catastrophic events like the
LUSI mudflow (Rubonis, 1991b). By learning from
both local and international experiences, and
through the implementation of well-planned
economic recovery initiatives, it is possible to
restore livelihoods and promote sustainable
economic development in disaster-affected regions.

living conditions and future prospects. These
psychological effects are compounded by the
disruption of social networks and community
structures, which are vital for emotional and practical
support.

Mitigation strategies must address these social
dimensions by incorporating psychological support
and ensuring transparent communication from
authorities. According to a study conducted by the
International Federation of Red Cross and Red
Crescent Societies (IFRC, 2014), effective disaster
response includes psychological first aid and
ongoing mental health support to help individuals
cope with the aftermath of such traumatic events.
Establishing village halls as information centers can
serve as a pivotal strategy in this regard. These
centers can distribute accurate information, provide
a platform for community support, and build
residents' confidence in disaster management
efforts. For instance, the integration of mental
health professionals and trained volunteers in these
centers can offer immediate psychological
assistance, while regular community meetings can
keep residents informed and involved in recovery
plans.

the efficacy of these approaches. Research conducted
by Norris et al. (2002) on disaster mental health
services highlighted the importance of communitybased interventions in mitigating the psychological
impact of disasters. Similarly, a comparative analysis
of disaster recovery efforts in Japan and the United
States by Uchida et al. (2011) demonstrated that
communities with robust communication channels
and mental health support systems exhibited better
psychological resilience and quicker recovery.
In conclusion, addressing the social and psychological
impact of the Lapindo mudflow requires a
comprehensive approach that includes psychological
support,
transparent
communication,
and
community engagement. By leveraging the
experiences and best practices from other disaster
recovery efforts globally, authorities can develop
effective strategies to mitigate the adverse effects on
residents, thereby fostering a more resilient and
informed community.

Village can be significantly improved, ensuring that
the residents are better equipped to face future
disasters with confidence and resilience.
3.3 Environmental
Measures

Degradation

and

Control

The environmental damage caused by the toxic
mudflows in Sidoarjo has been extensive, adversely
affecting soil quality, water sources, and overall
biodiversity. Phenol contamination, in particular,
poses a long-term threat to the ecosystem. According
to Lestari et al. (2011), phenol contamination has
significantly reduced biodiversity in the region,
impacting both plant and animal life. The toxic
substances present in the mud, such as phenol, can
persist in the environment, leading to prolonged
ecological damage if not properly managed.
3.3.1 Bioremediation Techniques
Bioremediation has emerged as a promising control
measure to mitigate the environmental impact of the
toxic mudflows. This technique involves the use of
microorganisms to break down harmful substances
into less toxic or non-toxic compounds. Studies
conducted in various countries, such as the United
18

States and Canada, have shown the effectiveness of
bioremediation in dealing with oil spills and other types
of chemical contamination. For instance, a study by
Jones et al. (2010) demonstrated that bioremediation
reduced phenol levels in contaminated soil by more than
70% within six months. Applying similar techniques in
Sidoarjo could help restore soil quality and support the
recovery of local biodiversity.
3.3.2 Diversion of Mud into the Porong River
Another proposed strategy is the diversion of mud into
the Porong River. This method aims to prevent further
land degradation and manage the volume of mud being
produced. However, this approach raises concerns
about potential flooding and water pollution. According
to a study by the Environmental Protection Agency
(EPA) in the United States, diverting contaminated
materials into water bodies must be carefully managed
to avoid secondary pollution. The construction of more
effective embankments and the installation of control
pumps are essential measures to mitigate these risks.
These structures can help control the flow of mud,
prevent flooding, and minimize the spread of toxic
substances.
Empirical evidence from previous studies supports the
effectiveness of these control measures. For example, a
LUSI Burst: Overcoming … / Retno Tri Nalarsih

comparative study by Wang et al. (2012) on flood
control measures in China and the Netherlands found
that well-designed embankments and pumping
systems significantly reduced the risk of flooding in
areas prone to water-related disasters. Additionally, a
study by Smith et al. (2015) on the use of
bioremediation in oil spill sites in Alaska showed that
microbial treatments accelerated the breakdown of
toxic substances, leading to faster ecological recovery.

By drawing on these insights and incorporating proven
strategies, this research aims to contribute to the
development of effective disaster recovery and
mitigation systems for the Lapindo mudflow and
similar environmental crises.
3.4 Infrastructure and Urban Planning
Overview of Infrastructure Integrity and Urban
Planning The failure of mud embankments in Sidoarjo
has underscored the urgent need for robust
infrastructure and strategic urban planning. Effective
urban planning is essential for mitigating risks and
enhancing the resilience of communities against future
disasters. According to Nugroho (2012), integrating
disaster risk assessments into urban planning is
fundamental to strengthening infrastructure and
ensuring community safety. This section delves into
infrastructure and urban planning strategies,
supported by empirical evidence and expert opinions
from various countries, to provide a comprehensive
understanding of best practices in disaster mitigation.
Reinforcement of Embankments and Flood Control
Systems One of the critical infrastructure projects in
mitigating mudflow disasters is the reinforcement of
embankments. Empirical studies, such as those

The environmental degradation caused by the Lapindo
mudflow necessitates the implementation of effective
control measures to mitigate its impact. Bioremediation
techniques and the diversion of mud into the Porong
River, supported by robust embankments and control
pumps, can help manage the ecological damage.
Empirical evidence from previous studies underscores
the potential success of these strategies. By integrating
these approaches, authorities can work towards
restoring the affected areas and preventing future
environmental disasters.

conducted by Setiawan et al. (2015), have shown that
reinforced embankments significantly reduce the risk of
collapse during extreme weather events. In Japan, for
instance, the use of advanced materials and engineering
techniques in embankment construction has proven
effective in preventing flood-related disasters
(Yamamoto, 2018). Similarly, the Netherlands employs
sophisticated flood control systems, including levees
and storm surge barriers, which have been instrumental
in protecting low-lying areas from flooding (de Moel et
al., 2014).
Dual-Purpose Strategy: Economic Recovery and
Disaster Awareness Converting affected areas into
tourist attractions serves a dual-purpose strategy that
promotes economic recovery and raises disaster
preparedness awareness. In New Orleans, postHurricane Katrina recovery efforts included developing
tourism centered around the city's resilience and
recovery. This approach not only rejuvenated the local
economy but also educated visitors on disaster
preparedness and resilience (Smith, 2010). Similarly, in
Iceland, the Eyjafjallajökull eruption site has been
transformed into a tourist destination, providing
economic benefits while highlighting the importance of
disaster mitigation (Gudmundsson, 2016).

In conclusion, the integration of disaster risk
assessments into urban planning is crucial for
enhancing community resilience and infrastructure
integrity. Reinforced embankments and sophisticated
flood control systems (Chen, 2016; Kaplanski, 2010a;
Lesk, 2016), coupled with innovative strategies like
converting disaster-affected areas into tourist
attractions, can significantly mitigate the impact of
toxic mudflows. Empirical evidence from various
countries demonstrates the effectiveness of these
approaches, providing valuable insights for the
development of more robust disaster mitigation
systems in Indonesia.
3.5 Community Engagement and Education
Community involvement is pivotal in disaster recovery
and mitigation. Engaging residents in planning and
decision-making processes can foster a sense of
ownership and cooperation (Gray, 2012a, 2012b; Zhao,
2019a). Educational programs aimed at increasing
awareness about the risks associated with toxic mud
and the importance of disaster preparedness can
empower residents. Studies by Wijaya (2013)
demonstrate that community-driven initiatives have a
higher success rate in disaster recovery. Establishing
regular training sessions and drills can ensure that the
community is well-prepared to handle future
emergencies.
Community engagement and education are effective in
various disaster-affected regions globally. In Japan, for
instance, community-based disaster risk reduction
(CBDRR) has been a cornerstone in managing frequent
natural disasters. According to Shaw (2006),
community participation in disaster drills, evacuation
planning, and hazard mapping significantly reduces
casualties and enhances resilience (Middleton, 2014;
Sprang, 2013; Yuan, 2016). This approach can be
adapted to the situation in Sidoarjo, where residents
can participate in designing evacuation routes,
understanding the health risks of phenol exposure, and
learning about safe practices during mudflow incidents.
Further empirical evidence from the United States
supports the importance of community involvement in
disaster recovery. A study by Paton and Johnston
(2001) in the context of wildfire preparedness
highlighted that communities that actively engage in
educational programs and preparedness activities are
better able to respond to and recover from disasters.
These programs often include workshops, public
meetings, and the distribution of informational
materials, all of which serve to inform and empower the
populace. This participatory approach can be mirrored
in Gempolsari Village (Goldmann, 2014; Smith, 2013a,
2013b), where authorities can collaborate with local
leaders to facilitate knowledge transfer and build a
culture of safety and preparedness.
20

In addition, research conducted in the aftermath of the
2004 Indian Ocean tsunami underscores the value of
local knowledge and community engagement in
recovery efforts. According to Rigg and Law (2005),
communities that leveraged local knowledge and skills in
rebuilding efforts were more successful in long-term
recovery (Loayza, 2012; Moussaïd, 2011). This finding
suggests that in Gempolsari Village, harnessing local
knowledge about traditional land use and water
management could enhance recovery strategies and
ensure they are culturally appropriate and sustainable.
In conclusion, the integration of community engagement
and education into disaster mitigation strategies is
crucial. By involving residents in decision-making,
providing continuous education (Cameron, 2015;
Kaplanski, 2010b; Lurie, 2018), and leveraging local
knowledge, authorities can enhance the resilience and
preparedness of communities facing the ongoing threat
of toxic mud flows. The empirical evidence from various
global contexts underscores that such participatory
approaches are not only effective but also essential for
sustainable disaster management.

4. CONCLUSION
This research concludes that effective mitigation and
recovery strategies are needed to overcome the
impact of the LUSI toxic mudflow in Sidoarjo. The
research found that despite efforts by authorities to
divert mud into the Porong River, turn affected areas
into tourist attractions, and use control pumps to deal
with flooding, challenges remain. One of the major
challenges was the collapse of the mud embankment
which raised public concern about the risk of flooding
and loss of life.
Using snowball sampling and phenomenology
methods, this research collected data from residents
around the Lapindo embankment area in Gempolsari
Village. Data was collected through interviews,
observation and photo documentation. The research
results show the importance of mitigation strategies
that involve village halls to provide information and
build residents' trust in facing disasters. Apart from
that, education and training for residents on how to
deal with emergency situations is also very important
to increase community preparedness.
It is hoped that these findings can provide insight for
the development of more effective disaster mitigation
systems in the future. Collaborative efforts between
government, communities and related organizations
are needed to ensure that mitigation and recovery
strategies can be implemented well and provide
maximum protection for the community.
