ABSTRAK

Sektor industri kecil dan menengah (IKM) berkontribusi cukup besar dalam perkembangan perekonomian Indonesia. Salah satu IKM yang bergerak di sektor ini adalah usaha circuit breaker. Mereka memiliki permasalahan defect produk. Lean sixsigma dipakai sebagai pendekatan improvement yang bertujuan untuk meningkatkan kualitas dengan cara mengurangi variasi produk. Tiga alternatif solusi, yaitu pelatihan staff, pengadaan fasilitas, dan modifikasi fasilitas. Alternatif perbaikan yang paling optimal untuk setiap proses adalah pelatihan untuk karyawan blanking dan pelatihan untuk karyawan electroplating. Alternatif perbaikan yang dipilih selanjutna diterapkan dengan tujuan meningkatkan sigma level dan mengurangi biaya kualitas. Penerapan alternatif menunjukkan kenaikan nilai sigma untuk proses blanking dari 3.96 sigma menjadi 4.05 sigma. Sedangkan untuk proses electroplating terjadi kenaikan nilai sigma dari 3.20 sigma menjadi 3.51 sigma.

Kata kunci: lean, waste, Sixsigma, defect, RCA, FMEA

 

ABSTRACT

The industrial sectors of small and medium enterprises (SMEs) have a considerable contribution to economic development in Indonesia. One SMEs engaged in the business sector is the circuit breaker. The main problem occurs the defected product is quite high and needs improvement, to increase product quality. Lean six sigma is used as improvement approach aimed at improving quality by reducing the variety of products. There are three alternative solutions, namely the training of staff, the purchase of the facility, and modification of the facility. The most optimal alternative for each process is blanking worker training and electroplating worker training. Training in both processes, then applied to increase sigma levels and reduce quality costs. Alternative implementations showed an increasing sigma value for blanking process from 3.96 sigma becomes 4.05 sigma. As for the electroplating process an increasing rate from 3.20 sigma becomes 3.51 sigma.
