PENINGKATAN PRODUKTIVITAS PADA PERTANIAN MELALUI PENDEKATAN LEAN SIX SIGMA DENGANMEMPERTIMBANGKAN INDIKATOR SUSTAINABLE AGRICULTURE DI PERKEBUNAN BELIMBING TASIKMADU

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.
