Abstract: The purpose of this study is to map out the value chain of cassava (Manihot esculeta) and to measure the
extent to which the cassava commodity in Toba Samosir District could affect the economics of the relevant
stakeholders. The method used in this research is descriptive-explorative with value chain mapping analysis
as the main problem solving tool. The sample population used in this study are all stakeholders along the
cassava supply chain in Toba Samosir Regency. From the study, we obtain three models of supply chain of
cassava, namely: (i) supply chain where cassava is consumed without processing, (ii) food supply chain
model, and (iii) cassava supply chain is processed into grade B tapioca flour. Afterward, a value chain
mapping was conducted to determine the margins of each node in the supply chain. The value chain map
reveals that the value engineering of cassava commodities is not yet optimal, where the final product produced
from the supply chain is still far below the potential possible value. Therefore, from this research
recommended some value-added improvement strategy, for example, diversify the product of cassava
derivative that is more valuable that is grade A tapioca flour and mokaf flour.
1 INTRODUCTION
Production of cassava (Manihot esculeta) in Toba
Samosir Regency occupies the sixth position in North
Sumatera Province. However, Toba Samosir
Regency still has great potential to develop cassava
commodity, because the area of land that is not
cultivated in Toba Samosir Samosir is bigger than
land area which is already managed. At this time the
area of land that is not managed in the District reached
33.392 Ha. From the demand side, in Toba Samosir
Regency there is a tapioca flour mill with 10ton / hour
capability. Total demand for tapioca flour at PT
Hutahaean is about 1000-1200 tons / month or
equivalent to cassava supply of 4000-4800 tons /
month. However, due to supply constraints, PT
Hutahaean is only able to get the supply of cassava as
much as 3400 tons / month.
Along with the development of cassava based
processing industry in Toba Samosir regency in
recent years, people's desire in producing cassava as
one of agriculture commodity also increases. This is
reflecting by the increase of the cassava production in
last 3 years (BPS, 2015). However, there is currently
no systematic study that maps the value chain and
measures the extent to which this sector affects the
economies of the respective stakeholders. Therefore a
research that can describe and analyze the
performance of supply chain and value chain of
cassava commodity in Toba Samosir regency is
needed. This study aims to determine the role and the
importance of each stakeholder in the cassava
industry and create a value chain of cassava that can
provide added value for the stakeholders.
2 METHODOLOGY
The method used in this research is descriptive-
explorative, research with problem solving which is
explored widely about things that influence the
happening of something based on the fact that
happened in the field. The research technique used in
this research is survey, which is direct observation to
know the actual condition of research object. In
addition to the survey also conducted interviews,
which are direct questions and answers to relevant
agencies such as agriculture and farmer groups and

stakeholders such as farmers, collectors, retailers,
cassava processing industries, distributors, retailers
and consumers about the situation or reality that
occurred in the field, the more the number of
respondents then the data obtained will be more valid
a. Sampling method
The sampling method was done by snowball
sampling, the sampling was done gradually, the
first thing to do was to determine the key
informant in the cassava farmer who can give
information and this person also used as informant
to identify other person as sample which is
considered can give information. Based on
snowball sampling method obtained 48
respondents which consist of 30 farmers, 10
middlemen, 7 retail traders and 1 tapioca industry.
b. Data analysis
Value chain analysis refers to a series of activities
required to present a product or service starting
from a conceptual stage, followed by several
stages of production, to delivery to end-
consumers and destruction after their use
(Kaplinsky & Morris, 2000).
c. Value chain mapping
Identify each part of the production process and
identify where steps can be eliminated or
improved. Improvements made aim to cut
production costs or increase productivity (Porter,
1985).
d. Value chain analysis
This analysis aims to identify opportunities for
value enhancement on the value chain map.
Improved value chains can be performed on
various sides such as processes, products,
resources and functions. Value chain
improvements aim to improve efficiency, product
diversification, resource optimization and
establish the most important activities in the value
chain.
3 RESULT AND DISCUSSION
3.1 General Overview of the Study
1. Location and geographical state
Toba Samosir is a regency in North Sumatra
Province with Balige as its capital. Toba Samosir
Regency consists of 16 districts and 244 sub-
districts. Toba Samosir Regency covers an area of
2,021.80 km
2
and is located between 2°03' and
2°40' North latitude and between 98°56' and
99°40' East longitude.
2. Social economic and environmental policies
According to Toba Samosir's central statistics
agency in 2014, over the past three years
economic growth in Toba Samosir has always
been positive. In 2013 the amount of GDP per
capita Toba Samosir district reached Rp 28.24
million with an increase rate of 12.36%. Tobacco
PDRB contributes 1.24% to the formation of
GRDP of North Sumatra. The large population of
Toba Samosir Regency depends on the
agricultural sector. Agriculture becomes the
mainstay sector for Toba Samosir Regency in
moving the local economy. In 2016 this sector
contributed significantly in the formation of
GRDP Regency Toba Samosir, which is about
34.93%. Toba Samosir regency is one of
producing centers of rice, corn, cassava, and
andaliman in North Sumatra.
3. Production and productivity of cassava in Toba
Samosir district
Production of cassava in Toba Samosir Regency
fluctuated where there is a decrease or increase in
the number of production each year. Based on
data obtained from BPS in 2005-2016 shows that
the production of cassava in Toba Samosir
Regency has a positive trend and move
exponentially. The exponential movement means
that cassava production will increase
continuously. In 2010-2012 a significant increase
in cassava occurred due to the presence of a
tapioca starch factory in Toba Samosir Regency,
PT Hutahaean. However, in 2012-2014 cassava
production has decreased very sharply. This
happens because of the prolonged dry season that
occurred in 2013-2014. While the productivity of
cassava in Toba Samosir Regency has a positive
trend and experienced a linear growth, this means
that cassava productivity will increase in the long
term. Increased productivity of cassava in Toba
Samosir District is caused by several factors
among others the use of superior seeds and the
increasing ability of the community in processing
cassava farming.
3.2 Supply Chain Mapping
According to (Chopra & Meindl, 2001) the supply
chain consists of all parties involved, directly or
indirectly, to meet customer demand. Based on data
that have been collected from the interview and
observation obtained 3 models of supply chain of
cassava commodity in Toba Samosir Regency (Fig.
1).

Figure 1: Cassava supply chain mapping
The description of the three models of supply chain is
as follows:
4 Model of cassava supply chain without processing
The simplest supply chain model is the
unprocessed cassava supply chain, in this chain
there are only 3 actors namely farmers, small
traders and consumers. Small traders act as
intermediaries between farmers and consumers.
The economic value of cassava in this supply
chain model is low, this is because cassava does
not undergo processing. Estimated around 2%
supply of cassava in Toba Samosir Regency goes
into this model.
5 Model of processed food supply chain of cassava
This supply chain model consists of five actors,
namely farmers as suppliers of raw materials,
middlemen as cassava collectors from various
farmers, food industry that acts to process cassava
so as to have a higher economic value, retailers act
as distributors of processed products of cassava to
consumers and consumers act as end-product
users. In this supply chain there is an increase in
the economic value of cassava, as it has
undergone processing. Examples of processed
products of cassava contained in Toba Samosir
Regency are crisps and wet cakes. It is estimated
around 6% supply of cassava in Toba Samosir
regency goes into this model.
6 Tapioca supply chain model
This supply chain is the most complex chain. It
can be seen from the number of actors who play a
role and the production process of its products. In
this supply chain there are 8 actors, namely
farmers, middlemen, tapioca factories,
distributors, industries with tapioca flour raw
materials, retailers and consumers. In this supply
chain model the economic value is higher than in
the previous supply chain model. In this model
cassava will be processed by PT Hutahaean into
tapioca flour with a large scale of 800-850 tons /
month. The products produced will be distributed
by the distributors to other places and tapioca
flour based industries. It is estimated around 92%
supply of cassava in Toba Samosir Regency goes
into this model.
3.3 Value Chain Mapping
Based on the above supply chain map, we get a
value chain for each model of supply chain of
cassava commodity in Toba Samosir Samosir
(Fig. 2)

Figure 2: Cassava value chain mapping
In the value chain of cassava in Toba Samosir
Regency, there are several actors ranging from
farmers, cassava processing industry to retail traders
(retailers). Farmers in this value chain function as the
party that produces cassava. In general, farmers grow
cassava for additional income, this is due to the low
economic value of cassava compared to other crops
such as rice, corn and coffee. However, since the
establishment of PT Hutahaean in Toba Samosir
Regency can increase the desire of the community in
planting cassava. The second perpetrator is the
collector, in the cassava value chain, the middleman
or the collector acts as an intermediary between the
farmer and the industry or the farmer with the
consumer. The middlemen will generally collect the
cassava directly to the location where the farmers will
then sell it to consumers or industries with higher
selling prices.
One of the actors who play an important role in
the cassava value chain is the cassava processing
industry. Industry plays a significant role in absorbing
cassava produced by farmers and processed into
products with higher economic value. Furthermore,
products processed by the industry will be distributed
through distributors to the next industry or to retailers.
And the next actor retailers or retail traders, retail
traders are traders who conduct buying and selling
activities directly to consumers. In addition to the
actors directly involved in the cassava value chain
there are some actors who are not directly involved
but have a role in supporting the improvement of the
cassava value chain that is the government. The
government through the agricultural service strongly
supports the development of cassava agriculture with
the provision of superior seeds and agricultural
equipment and agricultural machinery. The
agricultural service through farmer groups scattered
in each village became a place of farmers in
channeling the aspirations of farmers and farmers to
obtain agricultural knowledge through extension
activities.
3.4 Value Added Calculation
The concept of added value is one of value
development that occurs because of inputs that are
treated on one commodity (Agni, 2013). Value added
is calculated from value added during the production
process and marketing process (Hayami, et al., 1986).
Based on the results of interviews conducted on
actors contained in the value chain regarding the costs
required in the process of cassava production and the
profits derived from the sale of cassava products, it
can be calculated the value added obtained by each
supply chain actor in the cassava commodity value
chain system.

Based on the results of interviews at the study site, it
is known that cassava does not have a stable price, the
price is determined through negotiation between the
seller and the buyer. In addition, the price of cassava
also depends on its quality. Based on the analysis
(table) that the added value in each supply chain in
the value chain system is different.
3.5 Challenges for Development and
Commercialization of Value Chain of
Cassava in Toba Samosir Regency
a. Market opportunities and access to market
The destruction of infrastructure in areas far from
urban areas makes the actors in the value chain not
optimal in developing cassava commodities. This
is due to the difficult access to agricultural areas
and the high cost of transportation
b. Low diversification of cassava
In general, cassava in Toba Samosir Regency is
only used as animal feed, direct consumption and
raw material of tapioca flour. Whereas cassava is
a commodity that has many derived products, so
that will produce a high value product if
experiencing proper processing.
c. Lack of community awareness in managing
cassava farming
In general, cassava farming areas in Toba Samosir
district are poorly maintained, this is due to the
low level of awareness and ability of farmers to
cultivate cassava farming.
3.6 Recommendations for Increasing
Value Added Strategies for
Stakeholders
1. Facilitate the access of farmers to the market, this
is realized through the government by improving
the infrastructure of remote areas such as
Amborgang villages.
2. To diversify the products of cassava, cassava is
processed into high-value products such as
improving the quality of tapioca flour that is
currently into grade A, cassava processing into
mocaf meal
3. Increase the ability of each actor in the chain,
such as giving superior seeds to farmers and

providing agricultural extension and the use of
new technology in industrial processes.
4. Establishment of village-owned small-size
enterprise so as to increase people's creativity in
processing cassava.
4 CONCLUSION
Based on the analysis of value chain of cassava
commodity in Toba Samosir Regency is divided into
3 parts namely supply chain mapping, value chain
mapping and value added calculation. Mapping of
supply chain of cassava in Toba Samosir Regency,
there are 3 model that is, cassava supply chain model
without processing process, food supply chain model
and tapioca flour supply chain model. Actors
involved in the supply chain model include farmers,
middlemen, retailers, industry, retailers, and
distributors. However, the effort to develop the added
value of cassava commodity in Toba Samosir
Regency has not been optimal yet. From the results of
value-added analysis conducted can be seen that
farmers get the lowest added value and retail traders
get the highest added value. To be able to increase the
value in the value chain can be done on the side of the
process, products and functions. On the side of the
process can be done with the use of technology in
processing, improving on the product side can be
done with diversification while on the side of the
function can be done to produce a positive impact for
value chain actors.
