Efesiensi Teknis Usaha Tani Kentang di Kabupaten Lumajang

Abstract

Potatoes has important role in food security. It can substitute main food crop as rice.
Lumajang Regency is one of main potato producers in East Java, Indonesia. Therefore, potato is
expected to make high contribution toward regional GDP. However, the annual productivity of
potato in Lumajang has been below national level. There was a productivity gap as well as 3-5
tones per hectares towards national level in the last years. This study was aimed to determine: 1)
technical efficiency achievement among potato farmers, 2) technical efficiency determinant in
potato farming. This study was conducted in Argosari village, Senduro District, Lumajang
Regency. Sixty farmers was randomly selected and structurally interviewed by questionnaire.
Stochastic frontier analysis was employed to determine the objective. The result showed that: 1) the
average technical efficiency which was achieved by sampling farmers is 0.59 or 59%. It means that
potato farmers can produce 59% from their maximum production. For about 67% of sampling
farmers ran their potato farming under inefficient condition. 2) There are two factors which have
significant effect toward technical efficiency: household size and crop system. Household has
opposite effect toward technical efficiency. Mixed cropping system is more efficient than sole
cropping one.
