1. Introduction
Transportation has a very important role in achieving the goals of economic
development in a country. The importance of transportation for the people of
Indonesia is influenced by the geographical condition of Indonesia which consists
of thousands of islands. The need for transportation in an area is caused by the
461
interaction between social and economic activities in the area, the human desire to
travel is never ending and the many needs that cause displacement from one place
to another (Mahmudi, 2009).
The success of development is strongly influenced by the role of
transportation as the lifeblood of development. The availability of public
transportation in an area is very necessary in order to meet the transportation
needs of the community, with this public transportation it can balance the density
on roads caused by the high volume of vehicles on the road (Vian, 2017).
According to Ardiyansyah (2015), passenger public transportation is passenger
transportation carried out using a rental or payment system, such as city
transportation (buses, mini buses, etc.), trains, water transportation, and air
transportation. The main purpose of the existence of this passenger public
transport (AUP) is to provide good and proper transportation services for the
community.
The integration of intermodal transportation services plays an important role
in realizing an effective and efficient integrated public transport service.
connected and smooth or unimpeded during its journey (Listantari., et el 2021).
According to National Transportation System (2005), the purpose of the
integration of intermodal transportation services is to eliminate non-physical
barriers such as service tariffs, information systems for transportation operational
schedules, ticket payment systems and others. The integration of intermodal
transportation not only facilitates passengers to connect to the wider transportation
network but also with safe, comfortable and efficient transfers between the
various modes of transportation that serve them (Vespemann and Andrew, 2011).
It is important to improve the quality of transit services in order to attract
intermodal users (Vuchic 1999).
South Sumatra with a population of more than 1.8 million people (in 2018)
has been clarified as a Mentropolitan City. Therefore, the development of mass
transportation must be realized. In accordance with the definition in Law 26 of
2007 concerning spatial planning, the Palembang Raya metropolitan area has
fulfilled the requirements for clarification of a metropolitan area, namely the
existence of functional relationships and an integrated regional infrastructure
network system with a total population of at least 1,000,000 (one million). soul. In
this case, the core urban area (Palembang City) with the surrounding urban area
(part of the Banyuasin district and Ogan Ilir district) has functionally formed an
462
integrated urban area including the provision of regional infrastructure networks
(transportation, energy, drinking water, etc.).
Currently, the public transportation system in South Sumatra has been
served by 8 Trans Musi corridors, 7 conventional bus routes, 5 angkot routes and
5 taxi companies. However, the role of the road-based public transportation mode
has not been able to overcome the increasingly evenly distributed congestion in
the symbol city in the past few years. This prompted the emergence of proposals
for the development of a light rail-based mass transportation system
(monorail/LRT) in South Sumatra.
Studies to prepare for the development of the mass transportation system in
South Sumatra have been initiated by several parties previously. The LRT
connects SMB II Airport with OPI Mall with a total route of 23.5 km from
northwest to southeast of Palembang City which is supported by 13 stations and 3
train cars. When using a 3 carriage train formation, the 4 person/m2 train can
accommodate 424 passengers.
This research was conducted with the aim of describing and analyzing the
performance of the Light Rapid Transit (LRT) transportation integration case
study of the South Sumatra LRT. Determination of problem boundaries in this
research is done so that the research becomes clearer and more specific. Based on
the research title, the limitation of this research is the performance of the Light
Rapid Transit (LRT) transportation integration, the South Sumatra LRT case
study as a form of implementing multimodal transportation in South Sumatra.
2. Theoretical Framework
Along with the development of time technology is developing very rapidly,
therefore it is necessary to repair and rejuvenate the urban public transportation
system, both facilities and infrastructure with various policies. According to
Hazian (2008), in general the form of human intervention for the improvement of
the transportation system is possible by 1) changing transportation technology; 2)
changing information technology; 3) changing vehicle features; 4) changing the
characteristics of the road segment; 5) changing transport network configuration;
6) changing operational and organizational policies; 7) changing institutional
policies; 8) changing travel behavior; and 9) changing activity options.
The National Transportation System Service in Ilham and Komalasari
(2017) is the creation of an effective transportation operation in the sense of safe,
high accessibility, integrated, sufficient capacity, organized, smooth, fast, easy,
463
timely, comfortable and affordable rates. Integrated in the sense of realizing inter-
and intra-modal integration in the infrastructure and service network which
includes development, guidance and implementation so that it is more effective
and efficient. In supporting reliable transportation services, optimal transportation
performance support is needed.
Transportation performance is the ability or potential of public
transportation to serve the needs of movement in an area, both in the form of
transportation of goods and transportation of people. Performance is also the level
of achievement or work result of the company from the targets that must be
achieved or tasks that must be carried out within a certain period of time (Hazian,
2008). To minimize obstacles during intermodal transfers, the integration of
intermodal transport services is one of the key success factors in its
implementation. The integration here aims to coordinate and promote hassle-free
and convenient services of high quality (Listantari et el 2021).
According to the Guidelines for Multimodal Integration (2019), the
objectives of transportation integration include 1) faster, cut waiting time and
transfer time; 2) easier, shorten walking distance, clarify information and provide
convenience in one system; and 3) more affordable, cost-effective with integrated
tariffs and payments.
Good integration between modes of transportation will make it easier for
people to use public transportation, it is hoped that if it is managed properly it will
increase public interest in using public transportation. The increasing needs of the
community have led to higher road access to support smooth movement from one
place to another (Cahiril, 2017).
3. Methods
The paradigm used in this research is constructivism
paradigm.Constructivism paradigm is a paradigm that puts observation and
objectivity in finding a reality or science. This paradigm views science as a
systematic analysis of meaningful action through direct and detailed observations
of the actors concerned.In this research, the researcher has determined the
research focus which can be described 1) Implementation of the Policy regarding
the activities carried out by the Provincial Government of South Sumatra in an
effort to realize the Light Rapid Transit (LRT) development program in South
Sumatra; 2) the development of integrated infrastructure is an effort by the
government to realize the concept of multimodal transportation by emphasizing
464
the synergy of each mode; 3) types of Benefits It is hoped that the integration of
Light Rapid Transit (LRT) transportation with other modes will provide benefits
to the community and support the multimodal concept where there is no
discontinuity of transportation modes; and 4) the degree of change that is expected
is that the Light Rapid Transit (LRT) transportation integration development
program that is set will trigger behavioral changes in residents to switch from
using private vehicles to mass transportation. Changes that occur will parse the
existing congestion level.
This research is a qualitative type of research which is stated by Bogdan and
Taylor (1993) as a research procedure that produces descriptive data in the form
of written or spoken words from people and observable behavior. Qualitative
research basically has a number of characteristics that distinguish it from other
types of research (Guba and Lincoln, 1985). Qualitative research is carried out in
an independent and free natural setting or in the context of a purity or wholeness
(entity), so that wholeness must appear as it is and there is no influence or
particular interest Moleong (2000).
In this study, the research instrument is the researcher himself (the author)
who is directly involved in the research. The researcher as the main instrument is
the researcher who plans, collects, and interprets the data. Determination of
informants in this study is based on the parties who master the problem, have data,
and are willing to provide data, besides that the determination is also based on the
criteria of objectives and benefits. Determination of informants in this study using
a purposive technique, where only certain people or parties will be used as
research objectives as a source of information. According to Sugiyono in
qualitative research, the concept of population and sample is not known. Sources
of information for qualitative research are informants or resource persons related
to research problems and by researchers are considered capable of providing
information and data (Sugiyono, 2007; Bungin, 2008).
4. Results and Discussion
The integration of the South Sumatra LRT has been carried out, namely
with Damri and Bus Rapid Transit (BRT) with the total number of passengers
integrating from 2019 to 2021, which can be seen in Figure 1.

From figure 1 the realization of passengers integrating has decreased
significantly due to the covid-19 pandemic with travel restrictions, although not as
much as at the beginning of 2020 in 2021, passengers who integrate have
increased. In 2019 the stations with the most passenger integration were at DJKA
and Bumi Sriwijaya stations, in 2020 the most were at DJKA and Ampera
stations, while in 2021 the most were at DJKA and Ampera stations (Ministerial
Regulation No. 119 Years 2018). The South Sumatra LRT integration stop facility
is approximately 5 to 25 meters from the station and is equipped with ramp
facilities and guiding blocks on sidewalk access as shown in Figure 2.

In order to improve integration services, one of the latest South Sumatra
LRT integration programs is BTS (Buy The Service) which is a form of
integration service between South Sumatra LRT and Teman Bus, aimed at
facilitating the mobility of the people of South Sumatra in transportation with the
routes in Table 1 (Presidential Regulation Number 116 of 2015).

Besides being integrated, the South Sumatra LRT is also friendly to service
users for vulnerable groups by providing special and easily accessible facilities.
According to Law No. 25 of 2009, vulnerable groups are the elderly, children,
breastfeeding mothers, pregnant women, disabilities, and victims of natural/social
disasters. A number of facilities and infrastructure that must be met in the
implementation of disability-friendly public services such as the provision of
wheelchairs/sticks/cracks, easily accessible entrances, ramps with vines, special
lifts for vulnerable groups equipped with braille letters, hallways that connect all
rooms, toilets special for vulnerable groups, special counters for vulnerable
groups, special waiting rooms for vulnerable groups, special guidance blocks for
vulnerable groups, special parking for vulnerable groups that are easily accessible,
assistive devices for the blind, hearing aids, children's play areas and
lactation/breastfeeding rooms (Amin, 2008).
5. Conclusion
From the discussion of theoretical discussions with experts/stakeholders, the
conclusions in this study are 1) the realization of the integration performance of
Light Rapid Transit (LRT) with Damri and Bus Rapid Transit (BRT) has
decreased significantly due to the COVID-19 pandemic; 2) in 2019, the largest
Light Rapid Transit (LRT) passenger integration performance at DJKA and Bumi

This study aims to look at the trend of Light Rail Transit (LRT) mass transportation during the covid-19 pandemic as a lesson for multimodal transportation courses. The type of qualitative research that becomes a research instrument is the researcher himself (the author) who is directly involved in the research. The determination of informants in this study uses purposive techniques where only certain people or parties will be used as research objectives as a source of information, namely Informant I: Head of the Section on the Utilization of Facilities and Infrastructure, Informant II: Officials making committees of public service agencies, Informant III: Managers of Passenger Numbers and Revenues, Informant IV: Train Travel Organizers. The results of the study are expected to be able to measure the level of understanding of cadets in the Multiomoda Transportation course. Through the pre-test as the average basis for cadets' knowledge of the Multimodal Transportation course of 87.00, then an intervention was carried out through education and material training based on the results of a research study of light rail transit (LRT) mass transportation trends before and after the Covid-19 Pandemic and a reassessment was carried out to obtain the average post-test results and the results changed to 91.86. Through the Paired Sample T-Test test, the significance value of the pre-test and post-test can be tested, a significance value of 0.000 is obtained, which means that there is a significant difference between the pre-test and post-test values. Furthermore, it can be seen the Correlation value of 0.525 which shows the strength of the relationship of the 2 variables tested, namely pre-test and post-test.

The twenty-first century finds civiliation heavily based in cities that have grown into large metropolitan areas. Many of these focal points of human activity face problems of economic inefficiency, environmental deterioration, and an unsatisfactory quality of life—problems that go far in determining whether a city is "livable." A large share of these problems stems from the inefficiencies and other impacts of urban transportation systems. The era of projects aimed at maximiing vehicular travel is being replaced by the broader goal of achieving livable cities: economically efficient, socially sound, and environmentally friendly. This book explores the complex relationship between transportation and the character of cities and metropolitan regions. Vukan Vuchic applies his experience in urban transportation systems and policies to present a systematic review of transportation modes and their characteristics. Transportation for Livable Cities dispels the myths and emotional advocacies for or against freeways, rail transit, bicycles, and other modes of transportation. The author discusses the consequences of excessive automobile dependence and shows that the most livable cities worldwide have intermodal systems that balance highway and public transit modes while providing for pedestrians, bicyclists, and paratransit. Vuchic defines the policies necessary for achieving livable cities: the effective implementation of integrated intermodal transportation systems.
