Abstract

PT. Karya Gemilang Indonusa is a manufacturing company manufacturer of all kinds of safety seals in Indonesia, one of which is Double Lock 300 plastic seal. A unix plastic seal is a safety seal or a security tool called security seals. The problem that occurs is when in the process of making there are defects in the product because at the time of production in PT. Karya Gemilang Indonusa still has products that have not met the standards that have been determined, it requires proper quality control analysis. The purpose of this study is to analyze how to reduce defective products in Double Lock 300 plastic seal products in PT. Karya Gemilang Indonusa. Using define, measure, analyze, improve, control (DMAIC) methods. At the Define stage, CTQ (Critical to Quality) made in Double Lock 300 plastic seal products obtained as many as 3 pieces. At the Measure stage DPMO measurements were taken and the average DPMO on Double Lock 300 plastic seal products was 25483 and a SQL (Sigma Quality Level) value of 3.6 sigma was obtained. Then the calculation of Yield and obtained the average percentage of Yield is 93%. At the Analyze stage, data processing is done using pareto diagrams, and it is known that there are 3 types of defects, namely sonic damaged defect type with a percentage defect of 62.5%. In the second order there is a defect type Logo Truncated with a percentage of 22.5%. In the third order is the type of imperfect printing defect with a percentage of 15%. Based on the research that has been done, it can be drawn conclusions that the type of defect Sonic Damaged which is the dominant defect with a percentage of 62.5%, then look for the factors that cause the defect using Fishbone diagram. Once known the cause of defect, improved stage using Failure Mode Effect and Analysis (FMEA), obtained the highest Risk Priority Number (RPN) value of 360 in ultrasonic machine element is less than maximum during sonic process. and recommended action given in the form of proposals for the creation of checksheets specifically for machine control. The next stage is the Control stage, at this stage quality control is carried out in the form of a proposal in the form of checking the oldest machine on ultrasonic machines, more routinely conducting regular maintenance of machines, providing training to workers to improve work skills. Keywords : DMAIC, Double lock 300, Quality Control PT. Karya Gemilang Indonusa adalah sebuah perusahaan manufaktur produsen segala jenis segel pengaman diindonesia salah satunya segel plastik Double Lock 300. Segel plastik unix adalah segel pengaman atau sebuah alat keamanan yang disebut dengan security seals. Masalah yang terjadi adalah ketika dalam proses pembuatannya terdapat produk yang mengalami defect karena pada saat Produksi di PT. Karya Gemilang Indonusa masih terdapat produk yang belum sesuai standar yang telah ditentukan, maka dibutuhkan analisa pengendalian kualitas yang tepat. Tujuan penelitian ini adalah untuk menganalisa bagaimana cara mengurangi produk cacat pada produk segel plastik Double Lock 300 di PT. Karya Gemilang Indonusa. Dengan menggunakan metode Define, Measure, Analyze, Improve, Control (DMAIC). Pada tahap Define dilakukan pembuatan CTQ (Critical to Quality) yang terdapat pada produk segel plastik Double Lock 300 diperoleh sebanyak 3 buah. Pada tahap Measure dilakukan pengukuran DPMO dan didapatlah rata-rata DPMO pada produk segel plastik Double Lock 300 sebesar 25483 dan didapatlah nilai SQL (Sigma Quality Level) sebesar 3,6 sigma. Kemudian dilakukan perhitungan Yield dan didapatlah rata-rata persentase Yield yaitu sebesar 93%. Pada tahap Analyze dilakukan pengolahan data menggunakan diagram pareto, dan diketahui terdapat 3 jenis defect yaitu jenis defect Sonic Rusak dengan presentase defect 62.5%. Pada urutan kedua terdapat jenis defect Logo Terpotong dengan presentase 22.5%. Pada urutan ketiga yaitu jenis defect Printing Tidak Sempurna dengan presentase 15%. Berdasarkan peneleitian yang sudah dilakukan maka dapat ditarik kesimpulan yaitu jenis defect Sonic Rusak yang merupakan defect dominan dengan persentase 62,5%, lalu dicarilah faktor-faktor penyebab defect tersebut menggunakan Fishbone diagram. Setelah diketahui penyebab terjadinya defect, dilakukan tahap Improve dengan menggunakan Failure Mode Effect and Analysis (FMEA), didapatlah nilai Risk Priority Number (RPN) yang paling tinggi yaitu sebesar 360 pada Element mesin Ultrasonic kurang maksimal pada saat proses Sonic. dan recommended action yang diberikan berupa usulan untuk pembuatan checksheet khusus untuk pengontrolan mesin. Tahap selanjutnya adalah tahap Control, pada tahap ini dilakukan pengendalian kualitas dalam bentuk pemberian usulan berupa pengecekan mesin tertuama pada mesin Ultrasonic, lebih rutin melakukan perawatan mesin secara berkala, memberikan pelatihan kepada pekerja untuk meningkatkan ketrampilan berkerja. Kata Kunci : DMAIC, Double lock 300, Pengendalian Kualitas
