|
Infrastructure development
in Lampung, especially toll roads, is urgently needed to support mobility,
increase the distribution of goods and services, especially in areas with
high levels of devel-opment and it can reduce
congestion on a number of Trans-Sumatra Roads in Lampung, there some points
or areas are the main routes, which is able to support the economy
constrained by traffic jams and inadequate roads. This study aims to examine
whether the construction of the toll road has had the expected im-pact and achieved the above goals. A number of sectors
are used as the main study in this research, namely Population, Employ-ment and Unemployment; Industrial and Commercial; Retail;
Housing area; and Business Operational Efficiency. This study us-es empirical studies, which use field data as the main
source, such as the results of interviews and observations. The results of
the study show that the positive impact of infrastructure development in the
short term has been felt by the community, especially in terms of business and
retail operational efficiency. However, vari-ous
studies have stated that the biggest impact on infrastructure development is
in the future, especially with massive population growth which will certainly
increase the capacity of the economic ecosystem, even forming a new economic
ecosystem |

INTRODUCTION
Infrastructure
development in Lampung, especially toll roads, is very necessary to support job
mobility, increase the distribution of goods and services, especially in areas
with a high level of development and reduce congestion on a number of Sumatra
Cross Road Routes in Lampung, where a number of points or areas that are the
main routes that are able to support the economy are constrained by congestion
and unfit roads. Toll road infrastructure has a very important role in
supporting the economy, social, culture, unity and unity of the community in
terms of interacting, binding and connecting between regions in Indonesia. Toll
road infrastructure is also a facility that connects production sources,
markets and consumers. Lampung Province is one of the areas affected by toll
road construction. The construction of the toll road will undeniably have an impact
on the socio-economic conditions that exist in the future in the area around
the toll road. One of them is Lampung Province, as one of the areas affected by
development.
Economically,
it has an impact on changes in labor patterns, business opportunities, and
industrial growth that cannot be avoided. The conversion of land from community
housing and agriculture to toll roads has made investors enter into businesses
in the industrial sector, so as to change the livelihoods of people who were
previously farming into factory workers or small and medium enterprises (SMEs).
In line with that, industrial development tends to be followed by property
investment in the form of housing for workers. The impact of development in the
economic sector will be utilized in the future by the people in Lampung
Province.
Policy
impact analysis is included in the objectives and scope of the evaluation
study, as revealed by (Weiss, 2022), (Wibawa et al., 2014) and (Anggara, 2014). (William, 2013), stated
that the purpose of evaluation analysis is more about measuring the effects and
impact of a program/policy on society. Measuring the effect of a policy on
people's lives is to compare the conditions between before and after the
policy. Soemarwoto in (Giroth, 2004) said that
impact is a change that occurs as a result of an activity. Soemarwoto
further explained that "these activities can be natural, in the form of
chemistry, physical and biological, can also be carried out by humans in the
form of analysis of environmental impacts, development, and planning. These
impacts can be biophysical, social, economic and cultural". Meanwhile,
according to (Anggara, 2014), impact is a
change in physical or social conditions as a result of policy output. The
effect produced by an intervention program on the target group and the extent
to which the effect is capable of giving rise to new patterns of behavior in
the target group (impact). The results produced by program interventions in the
target group, both expected and incapable of giving rise to new behaviors in
the target group (effect). Dye, Anderson, Lester and Stewart in (Winarno, 2017) and (Anggara, 2014) reveal that
basically the impact of a public policy has several dimensions that must be
taken into account in the discussion of evaluation. There are five dimensions
of policy impact according to Dye in (Anggara, 2014), namely:
1. The impact
of policies on public affairs and the impact of policies on the people
involved. Thus, the goals in public policy that are expected to be influenced
by the policy should be limited, and the expected impact of the policy should
be determined from the outset of the public policy.
2. Such
policies may impact circumstances or groups beyond the policy goals or
objectives of the policymaker previously thought. Policies can have an impact
on current and future conditions that will affect both target and out-of-target
groups.
The impact
of toll road infrastructure development policies, related to the process, will
not only have an impact on changes in natural conditions, but will also have an
impact on the socio-economic conditions of the surrounding community. According
to (Salim & Cooksey, 2019) the development
process gives rise to mobility so that one community group is connected,
sometimes it can even collide with other groups, and also collide social values
with each other. Large projects have the ability to cause shocks and imbalances
in the social environment. Both the development with great leaps and the
construction of large projects equally affect the social environment.
Furthermore,
(Salim & Cooksey, 2019) argued that
the nature of development also aims to cause diversity and diversification in
community economic activities such as agricultural development, industry,
mining, services and others. But it is impossible to forget about the balance
of the environment. There are several problems that can be identified:
1. Toll road
infrastructure development cannot always be enjoyed by all stakeholders, but
there are often widening socioeconomic gaps.
2. Infrastructure
development policies on the one hand cause diversity in the economic
diversification of the community, but on the other hand also cause
environmental degradation that is not conducive.
3. The
development process gives rise to mobility so that one group of people is
interconnected, sometimes even clashing with other groups, which can cause
shock and imbalance in the social environment.
4. The Policy
Strategy for infrastructure development is more viewed from the physical
environmental impact, while the socioeconomic environmental impact is much more
complex and long-term.
Theoretical
Framework
This section
provides a brief review of various economic theories about the role of public
infrastructure, in particular its relationship to output or growth. It also
serves as a background for building an economic model and choosing an empirical
approach to use in this research. Empirical models with infrastructure capital
are derived based on reviews.
Growth
Theory
In
traditional macroeconomic neoclassical growth theory, economic growth is driven
by exogenous factors, namely population dynamics and technological
processes. A strong analysis of how
corporate behavior and government policy actions can affect long-term growth
through the impact of technological advances
certainly cannot be done well. In
fact, the role of government in the growth process is often not looked at in
economic theory (Kuipers et al., 2018). However,
as will be studied, that new theory of growth gives a much greater role to
public infrastructure, namely to development.
Growth PathThrough Infrastructure
At a
theoretical level, infrastructure can be modeled to have an effect on each
output measure through two paths; directly as the third input in the production
function and indirectly by influencing the total productivity of factors (Agénor & Moreno-Dodson, 2006).
Direct
Effects
In standard
production functions where factors are gross complement, an increase in
infrastructure capital will have a direct impact on increasing the productivity
of other factors. This is especially clear if we examine in cases with a very
influential agenda (Kremer, 2013), for
example, if roads or bridges provide access to previously inaccessible areas,
which then allows productive investment there, or if the repair of electrical
or telecommunications networks so that it is possible some type of machine or
other more advanced equipment. But since infrastructure capital is also
believed to produce important externalities in various economic activities, its
net effect may be greater than expected from the effects of accumulating simple
factors. The relation to such indirect effects will be explained next.
Indirect
Effects
The
first indirect y ang effect relates to
maintenance, the durability of private capital, and the cost of
adjustment. Today, there is growing
evidence that infrastructure policies are biased towards the realization of new
investments by neglecting maintenance on existing infrastructure. The main
reason seems to be the reason for political economy (Maskin & Tirole, 2018), as well as (Dewatripont & Seabright, 2016).
Consequently, the service life of the infrastructure stock itself and the
private capital that utilizes it is reduced, such as trucks operating on broken
roads or machines connected to unstable voltage lines, so operating costs
increase (Engel et al., 2019). The case of
palliative private investment for devices such as electric generators.
Second,
infrastructure seems to have a microeconomic impact through a number of
channels, including increased labor productivity resulting from improved
infrastructure and information technology, reduced time wasted on work and
stress, as well as improved health and education, and so on . In addition, such improvements
are likely to encourage additional investment in human capital in the medium
and long term (Straub, 2018). Finally,
infrastructure can be a source of scale and scope of the economy across all
sectors of the economy. For example, as roads and railroads improve, transportation
costs decline, private companies benefit from economies of scale and more
efficient inventory management.
Gap Analysis
(Madden & Savage, 2018) found that
infrastructure improvements helped increase the national growth rate.
Infrastructure development helps to change the entire scenario of economic
activity in the country and this leads to an increase in GDP. (Sahoo et al., 2012) study the
effect of physical infrastructure on economic growth in the People's Republic
of China during the period 1975 – 2007. In their study, they calculated the
index of physical infrastructure with six sub-headings namely as follows: power
consumption, roads, energy consumption, telephone lines, railway lines, the
number of people using airways. In accordance with the findings, it can be seen
that infrastructure development has a tremendous influence on growth.
Infrastructure investment has a greater impact than public and private sector
investment. There is a one-way causality relationship from infrastructure
stocks to growth and a two-way causality relationship from infrastructure
stocks to public-private sector investments.
(Bougheas & Downward, 2020) study the
significant positive relationship between infrastructure and specialization
level and also state a strong non-monotonic relationship between infrastructure
and growth using the OLS regression model. The results of the study show that
economic growth initially accelerated due to infrastructure improvements and when
it reached its peak, economic growth also touched its highest point and after
that began to decline when additional infrastructure was installed. Researchers
are confident in this result because the phenomenon can occur, namely when
excess infrastructure creates problems to deal with it and its maintenance and
waste become a permanent source of economic problems. (Straub, 2018) used
physical indicators for four different sectors (telecommunications,
electricity, roads, and water) and applied two different approaches (growth
regression and growth accounting) to analyze the relationship between
infrastructure, growth, and productivity in Asian developing countries during
the period 1971 – 2006, with the interim conclusion that there was a
relationship between the three.
(Hong et al., 2011) studied the
relationship between transport infrastructure and regional economic development
comprising 31 regions in China in 1998-2007. In accordance with the results of
studies using the panel data method, it can be seen that toll road
infrastructure and drinking water have a significant effect on growth. In
addition, there is a positive effect on growth even in areas with low toll road
infrastructure. Meanwhile, water infrastructure contributes positively to growth
only when a number of investments are actualized. A study by (Fedderke & Bogetić, 2009) using panel
data for South African manufacturing during the period 1970-2000, and a series
of 19 measures of infrastructure, isolated the impact of endogenicity.
This paper develops instrumentation strategies that can be generalized to other
contexts. In their study, controlling the possibility of endogenicity
in infrastructure measures made the capital impact of physical infrastructure
not only positive, but also a large and economically meaningful impact.
As explained
above, researchers tried to examine the impact of infrastructure development on
economic growth, where the context studied was the construction of the BAKTER (Bakauheni-Terbanggi Besar) toll
road. In the study on gap analysis,
previous researchers examined economic growth in infrastructure development in general in qualitative and quantitative approaches,
while in this study the researcher will
examine economic growth in each sector
to detail the impact of toll road
development, so that it can be known which sector gets the most impact, and if
there are sectors that do not get the impact of infrastructure development, it
will be immediately identified. The sectors to be discussed are, Population,
Employment and Unemployment; Industrial and Commercial; Retail; Housing; and
Business Operational Efficiency. The data presented
is based on field data which is then
summarized in the form of graphs to make it easier for readers.
State of Art
Previous
research discussing the construction of toll roads related to improving the
economy of the people of Lampung has never been done before. The research
conducted by Muhammad Alfayyad Ryandika
entitled "Legal Protection for the Community against the Impact of Land
Acquisition of Toll Road Sections Divided by Large Pematang
Panggang" only discusses the general positive
and negative impacts on the community's economy with a focus on legal
protection of the rights of related communities (Ryandika, 2022). Research
conducted by the Magelang City Research and
Development Agency discusses strategies that need to be applied to empower the
community's economy, especially in the people of Magelang
City (Oerbawati,
et al, 2021). The research conducted by Uswatun Khasanah contains a
description of the positive and negative impacts of toll road construction for
the people of Kasreman Village, Geneng
District, Ngawi Regency, which is then associated
with an Environmental Impact Assessment (AMDAL) (Khasanah, 2017). Research by
Hayakawa and Tsubota found that toll road
construction can increase transportation speed so as to facilitate economic
activities and effectively affect the price of a good or service, one of which
is the price of butter in Japan (Hayakawa
& Tsubota, 2022). Research by
Xiaofeng on the impact of toll road construction on
socioeconomic and environmental in China (Xiaofeng, Siwei, Yue, 2021). Compared to
some of the previous studies above, the author's research here shows updates
related to how toll road construction affects people's economic growth based on
field data obtained from the research site and effectiveness related to toll
road construction policies in Terbanggi Besar, Lampung.
RESEARCH
METHOD
This study uses empirical studies, which use field data
as the main source, such as interviews and observations. Analysis through
empirical studies reviews patterns and behaviors that occur in the community.
Researchers use this method to see the process of community development and
growth from the economic side after the con-struction
of the Bakauheni-Terbanggi Besar
toll road (Sunggono, 2003).
While the re-search approach uses a qualitative approach, the analysis process
with the results of analytical descriptive data expressed in written or oral
form by accounting for the quality of sources and data (Fajar & Achmad, 2010).
The location of data collection is carried out in Lampung Province, where the
toll road was built. Research data is ob-tained from
behaviors or phenomena that exist around society that are seen through research
research. Parties engaged in the business field are
the main source of this re-search, while the general public as a source of
additional information (Soekanto, 1986).
Secondary sources in this study are books, journals, statistical data and other
references related to the study of infrastructure development as a support for
the community's economy. The collected data were obtained from the observation
process, interview and documentation process (Narbuko,
2005; Masri, 2008; Achmadi
& Nar-buko, 2005).
Furthermore, in the research conducted by Luo Xiaofeng, Liu Siwei & Yuan
Yue (2020) gave a conclusion that In
short is, highways have a huge driving effect on the economy and society, and
also have an important impact on the ecological environ-ment
from various aspects. It can be seen from the literature that domestic and
foreign studies are currently relatively weak in quantification, mainly due to
the lack of de-tailed data support. Therefore, systematic assessment of the
impact of roads on the economic, social, and ecological environment needs to be
carried out by collecting raw data and conducting scientific analysis, as well
as being the basis for realizing road planning involving sensitive protected
areas.
RESULT
AND DISCUSSION
Spatial policy is the
domain of the government, but community participation cannot be ruled out (Denhard & Denhart, 2003; Musso & Frederickson, 1999). This is because the community is the recipient
of the impact and at the same time as a driver for the country's economy. Integrated development is highly expected in
multi-sectoral development (Widodo, 2013). Such as the construction of the Bakauheni-Terbanggi Besar toll
road, which has been the hope of the community for a long time as a need for mobilization. The following are the results of developments
after the construction of the Bakauheni-Terbanggi Besar toll road.
Population, Employment
and Unemployment
Case studies shed light on how toll road projects impact population,
employment, or unemployment levels recorded. This is not to say that there are
necessarily effects on labor or migration but the study of those effects would
be too difficult and extensive if it examined at the aggregate data level. With this case study, it can be proven that with the improvement of infrastructure through the procurement of toll roads,
the employment trend has increased markedly after this road investment wasinaugurated, So it is concluded that there is a
possibility of impact on a sub-regional scale.
Here's a presentation of related data:
Figure
1 Population Growth
Source: BPS, 2022.
From the data above, it can be seen that the construction of the toll
road has an impact on increasing the population drastically, right after the
inauguration of the Bakauheni-Terbanggi Besar toll road. Then for employment growth can be seen
below:
Figure
2 Number of Large and Medium Industrial Labor
Source: BPS, 2022
Figure
3 Number of Large and Medium Industrial Labor
Source: BPS, 2022.
Based on data showing that employment is not affected by the construction
of toll roads, even in the previous year there were other variables and factors
that influenced the increase and decrease that steep on the graph of employment
development in Lampung. As for the open
unemployment chart, it can be seen as follows:
Figure
4 Open Unemployment Rate
Source: BPS, 2022.
From the chart, it is known that the infrastructure development carried
out does not affect the unemployment rate in Lampung. However, at the end of 2022, it began to
decline, it's just that it is not yet known whether there will be a significant
decline and whether the construction of the Bakauheni-Terbanggi
toll road is a factor, while this can only be a recommendation.
The problems of ppulation, employment and
unemployment however to some extent remain detrimental, the presence or absence
of toll construction. Therefore, the conclusion that the absence of investment
in the construction of toll roads or other adequate roads will hinder the
development of regions is certainly irresistible. However, the conclusion of
this infrastructure development needs to be held, both for short-term and
long-term investment, whether it has an instant or slow impact.
However, if we consider this series of cases carefully, the overall
conclusion is that the impact of road investment on the associated
order in the case study project is not
large enough to be able to see the impact above the level of
other factors. In short, the impact of road investment is not enough to bring
about noticeable changes to economic performance in the regions, particularly
in Employment and Unemployment. The complexity of the assessment is illustrated
by the case of the completion of road construction followed by a marked
increase in employment growth, but with
relatively slow growth it is necessary to conduct in-depth studies for its
long-term impact. For studies on other sektor can be
seen in the next discussion.
Industrial
and Commercial Development
There is much clearer evidence that road investment can have a major
impact on the development of industrial and commercial sites, as well as on the
location of economic activity. In the details of the data in the case study, it
is considered to have strong evidence that the use of space in
industrial/commercial sites is strongly influenced by the construction of toll
roads. These impacts are expected to have an effect on some site decisions at
the local level, i.e. attracting some businesses to the area and some points
related to development. In the third case it is thought that there is a
possibility but a more limited impact.
This is not something that is not planned, because basically the
procurement or construction of toll roads is more oriented towards increasing
economic growth and has the principle of paying attention to aspects of
regional potential (Widodo, 2013). The social
functioning of land use succeeds with macroeconomic interests. The construction
of toll road infrastructure requires a very large area of land; The financing
scheme implemented so far involves large-scale investors. Another source of
funding comes from the government through State-Owned Enterprises that are
basically profit-oriented (de Soto, 1989). For details of the industry chart in Lampung,
please see the following:
Figure
5 Large and Medium Industry Graphics
Source: BPS, 2022.
The graph shows that the construction of toll roads did not have a
direct and instant impact, where there was no significant increase after the
inauguration or even a
decrease, the peak of a large
industrial increase and is in
Lampung in 2016. For micro and small
industries can be seen the following:
Figure
5 Micro and Small Industry Graphs
Source: BPS, 2022.
In micro and small
industries also do not get direct and instant influence from
development projects, fortunately micro
and small industry charts show
stability, although of course with A number of
declines that occurred in some years.
Retail
Evidence of influence on retail development is strong, except in the
case of rural areas. The obvious development is that in each rest area within
the toll project environment, the large number of visits in the rest area is
the basis for the community to sell there; Daily necessities, snacks, souvenirs
can be found there. As for retail development, the rest is near the exit gate
of the toll road. However, retail
development, of course, is based on "local" demand and spending.
Therefore, the growth of retail activity in one area will largely replace
activity elsewhere in the sub-region. Therefore, the economic impact created
through the effect on retail development is essentially local. Apart from that, it does not mean dimming the
previous business, because basically the surrounding community will stick to
buying and selling activities as before, especially in big cities.
such as Bandar Lampung and Metro will remain crowded with economic
activity there.
Housing
The case study also provides strong evidence that housing development is
influenced by toll road construction. In this case study of the Bakauheni-Terbanggi Besar toll
road, there is evidence, that the level of construction of houses and housing
increased at locations near the toll road project, just before and after it was
built, such as the construction of a number of houses and
housing near the New Town toll exit. In some cases, these results are
supported by planning policy decisions to provide land on sites near
development projects.
In some cases of routes, there is a shortage of housing development in
contrast to higher levels of activity in more accessible locations. This affectsmostly involves a "shift" in housing
demand, as does the population within the sub-region or local area. Stimulating
housing development can encourage the growth of a particular community or city,
which is then capable of creating a new or larger economic cycle.
Business
Operational Efficiency
The impact of road investment is explored through business surveys.
Companies in areas where roads have been repaired were interviewed about the
quality of the transport network and whether the investment has reduced travel
time/costs, better access to suppliers and customers, better labor access, and
has benefited businesses. In all cases related to the construction of the Bakauheni-Terbanggi Besar expressway, the
majority of companies reported benefits
for business through an overall increase in travel time and costs, the specific
benefits cited varied but included faster business travel, easier movement of
goods, and better access to
customers/suppliers. In this regard, there are a number of statements
from the community.
"With the construction of this toll road, it makes it easier for us
to deliver passengers to their destination faster"
The above statement was taken from several people who work in
inter-provincial passenger transportation, which was then collected and
concluded as quoted above. Other quotes
like the following:
"The construction of this toll road reduces travel time and costs
in shipping goods, and can be comfortable resting if you are tired, although in
some rest areas facilities are not complete"
The quote was inferred from several freight
forwarders in various sectors, the answer shows that the profit is not only
time but also cost. The relationship between impact on site decisions or site
development and overall economic growth is less clear given the evidence
reported above about the absence of impact on data levels. Nonetheless, the
impact of this type of development is generally too limited to be detectable in
aggregated data. So, in the industrial and
service sector, the influence of this
toll road development project as a whole
still cannot be seen in data, but in
fact it has had some direct impacts,
which is expected in the future to have a greater long-termimpact,
namely faster economic growth.
CONCLUSION
From the presentation of the research results,
the conclusion that can be taken is that the positive impact of infrastructure
development for the short term has been felt by the community, especially in
terms of operational efficiency. business and retail. Meanwhile, data still cannot be seen the
impact, except on population growth, which has increased drastically after the
inauguration. However, various studies have stated that the biggest impact on
infrastructure development is in the future, especially with massive population
growth, it will certainly be me. increase the capacity of the eco-nomic ecosystem, and even form a new economic ecosystem.
