Tasikmadu Plantation is one of producer national superior fruit
comodities that known as the Tasikmadu Starfruit. This plantation is
always working to improve its productivity due to cost savings and
increasing revenues. The main focus on the observation of this research
is in nurturing and harvesting process.
This research uses Lean Sigma paradigm by means of combining
between Lean Thinking and Six Sigma methods that is intended to
improve productivity especially in nurturing and harvesting process,
where the indicator used is the productivity index. The means of
improvement is made to increase the productivity that selected based
on sustainable agriculture indicator in order to support the
sustainability of agriculture.
Based on the results of this research, two critical waste which is
made the focus of research was not utilizing resources and defect where
defect waste has a sub-critical waste such as natural devective and
chafed devective, whereas not utilizing resources waste has a subcritical
waste form of the excess use of pesticides and excess use of
fertilizer that use in the spraying and fertilization process. Based on the
calculation before improvement, the productivity index is at value of
73.37%. The best Alternatives that selected based on highest value and
highest increase of productivity index was the combination of the use of
alternative organic fertilizer and organic pesticide use (which has been
equipped with information systems dose). The value of productivity
index after the improvement was 74,74% or increased by 1,37% from
the productivity index before improvement.
