Abstract
Departemen GLS (General Lighting Services) PT. Philips Lighting Surabaya merupakan produsen lampu pijar. Pada pelaksanaan proses produksinya, perusahaan menemui beberapa kendala yang terkait dengan waste. Analisis lean six sigma dengan menggunakan value stream mapping menunjukkan terjadi defect di mesin finishing dan waiting di mesin mounting. EHS waste juga muncul yang mengindikasikan adanya dampak terhadap lingkungan dan kesehatan serta keselamatan pekerja. Pencarian akar permasalahan dilakukan dengan menggunakan tools RCA (5 whys) dan FMEA hingga memunculkan 15 penyebab utama terjadinya ketiga waste tersebut. Pembentukan tim Total productive maintenance, penelitian perbaikan kualitas bulb dan flare, serta eksperimen pengurangan jumlah jenis coil menjadi usulan alternatif yang bisa dilakukan perusahaan. Dengan menggunakan konsep value management didapatkan alternatif terbaik dengan melakukan pembentukan dan pelatihan tim Total productive maintenance. Alternatif ini meningkatkan nilai sigma defect dari 2,92 menjadi 3,08 dan sigma waiting dari 2,83 menjadi 2,89. Indikator dampak lingkungan juga mengindikasikan penurunan yang sejalan.
