2 METHODOLOGY
The research was conducted at Sungai Suci Farmers Group, Central
Bengkulu Regency, in September 2022. This group was formed in
2008, consisting of 20 farmers who live in Hamlet III Pasar Pedati
Village, Pondok Kelapa District. Members of farmer groups cultivate
cassava on dry land covering an area of approximately 65 ha. Farmers
grow cassava in monoculture with a planting time setting that ensures
the availability of fresh cassava raw materials continuously throughout
the year for the manufacture of chips, mocaf flour, and rengginang
mocaf.
The data collected in this study are data on processing and costs
(input) and results (output) of the processing business of three
processed cassava products, namely chips, mocaf flour, and
rengginang mocaf. Data was collected through focus group interviews
or Focus Group Discussions (FGD) and participating observations.
The FGD involved 6 respondents, five cassava processing farmers,
and one agricultural instructor. The researcher acted as a discussion
facilitator by using an interview guide. Meanwhile, participating
observations were carried out by observing the process of making
processed cassava products.
The data obtained were analyzed descriptively using two methods of
analysis. The first analysis method uses MBCR (Marginal Benefit Cost
Ratio) to see the additional profit as an indicator of economic feasibility
due to an additional variable cost [1], formulated as Equation (1),
where: Bn is the n-th income, and Cn is the n-th variable cost.
B(n + 1) – Bn (1)
=
C(n + 1) – Cn
The second analysis is the added value analysis using the Hayami
Method to describe the difference between the product value and the
cost of raw materials and other inputs but does not include labor [4].
The components of calculating the added value using the Hayami
Method are shown in Table. 1.
