Abstract

The main objective of this study is to identify and reduce product defects occurring during the production process. Data was collected from January to December 2023, with an initial defect rate of 8.65%, equivalent to 86,500 defects per million opportunities (DPMO). Through the application of the Lean Six Sigma method, the defect rate was successfully reduced to 6.16%, or 61,600 DPMO. The initial Sigma level was 3.82 and increased to 4.10 after improvements. This approach involves several key stages: Define, Measure, Analyze, Improve, and Control (DMAIC). In the Define stage, the problem is clearly defined, including identifying the most frequent types of defects such as cracks, surface blemishes, and size variations. In the Measure stage, data is collected and analyzed to identify problematic areas, using statistical tools like histograms, Pareto charts, and control charts. In the Analyze stage, an in-depth analysis is conducted to find the root causes of defects through methods like the 5 Why's and fishbone diagram. In the Improve stage, solutions are implemented to address the root causes, such as adjusting machine parameters, retraining employees, and enhancing raw material quality. In the Control stage, steps are taken to ensure that the improvements made can be sustained in the long term by implementing regular monitoring procedures and quality audits. Keywords : Lean Six Sigma, Product Defect, Production Process, Quality Product, DMAIC, Floor Tile.

Abstract

In line with technological advancements and increased consumer expectations, quality has become a key factor in the service industry. PT. XYZ, which operates in the aircraft maintenance field, faces the challenge of reducing defects in the aircraft painting touch-up process. This research aims to reduce these defects using the DMAIC method. The DMAIC phases include define, measure, analyze, improve, and control. In the define phase, it was found that dust defects were the most dominant. Initial measurements showed an average DPMO (defects per million opportunities) of 12,129 and a sigma of 3.773. Analysis using the Ishikawa diagram identified the root causes of the problem, and FMEA helped determine the priority root causes that needed immediate improvement. The main causes of the aircraft paint touch-up defects were material cleaning that left fibers on the surface to be painted, and the spray gun being in an un optimized condition for use. Suggested improvements included procuring the appropriate cleaning materials and implementing a preventive maintenance checklist for the spray gun. The implementation of these improvements showed a reduction in dust defects, with the DPMO dropping to 3,477 and sigma increasing to 4.209. These results demonstrate that the improvements made were effective in reducing defects and enhancing painting quality.Keywords: DPMO, sigma, DMAIC, dust defects, aircraft painting.

Abstract

Sistem Informasi Pengelolaan Sampah Nasional (SIPSN) limbah yang paling banyak di Indonesia adalah limbah makanan sebesar 40,1 %. Upaya pemerintah dalam menangani food waste sudah dilakukan seperti membuat peraturan mengenai sistem pengelolaan pangan dan edukasi agar masyarakat mengonsumsi pangan sesuai yang dibutuhkan dan lain-lain. Salah satu cara mengelola food waste dapat dimanfaatkan menjadi pakan ternak. Forum Kolaborasi & Komunitas Peduli Sampah (FOKKALIS) merupakan organisasi yang terbentuk dari masyarakat yang peduli mengenai sisa makanan. Fokkalis mengelola food waste untuk dijadikan pakan ternak, biogas dan pupuk. Alur pengolahan sisa makanan yang sudah terintegrasi dengan baik namun fokkalis terdapat beberapa menjadi kendala seperti belum memiliki database untuk penerimaan sisa makanan dan produk mereka yang diproduksi belum dapat dijual secara bebas. Sistem informasi diharapkan dapat membantu fokkalis dalam mengelola data dari penerimaan hingga data donatur. Perancangan sistem ini menggunakan metode Design Thinking, yang memiliki tahap Empathize, Define, Ideate, Prototype dan Testing. Pada tahap testing, penelitian ini menggunakan pengujian usability testing dengan perhitungan system usability scale (SUS) untuk menguji kegunaan prototipe. Hasil pengujian usability testing, pengguna dapat menggunakan dengan waktu rata-rata yaitu 10 menit 27 detik. Skor SUS dari pengujian ini sebesar 69,5 dimana skor ini masuk ke grade “C” dengan tingkat penerimaan tinggi.

Abstract

Penelitian ini bertujuan untuk mengoptimalkan pengelolaan persediaan bahan baku kulit pada proses produksi sepatu safety di PT. XYZ menggunakan metode Economic Order Quantity (EOQ). Permasalahan yang dihadapi perusahaan adalah ketidaktepatan dalam jumlah dan frekuensi pemesanan bahan baku yang menyebabkan tingginya biaya persediaan dan risiko kekurangan stok. Dengan menggunakan data kebutuhan tahunan sebesar 2.015.853 Ft², biaya pemesanan, serta biaya penyimpanan tahunan, dilakukan perhitungan EOQ untuk menentukan jumlah pemesanan optimal. Hasil analisis menunjukkan bahwa jumlah pemesanan yang efisien adalah sebesar 63.496 Ft² per order dengan frekuensi pemesanan sebanyak 32 kali dalam setahun. Total biaya persediaan (Total Inventory Cost) dapat ditekan hingga Rp 95.244.780. Selain itu, perhitungan Safety Stock sebesar 7.995 Ft² dan Reorder Point sebesar 38.160 Ft² disusun untuk mengantisipasi ketidakpastian permintaan dan waktu tunggu pengadaan. Penelitian ini menyimpulkan bahwa metode EOQ efektif dalam meningkatkan efisiensi pengelolaan persediaan bahan baku serta menjaga kesinambungan produksi. Kata kunci: Economic Order Quantity, persediaan, bahan baku kulit, safety stock, reorder point
