Abstract

Dalam dunia industri banyak persaingan yang terjadi untuk memenuhi kebutuhan konsumen. Persaingan tersebut meliputi produk, proses produksi maupun kinerja dari industri. Produk yang dimaksud adalah hasil dari produksi dimana ada atau tidaknya cacat. Untuk proses produksi dapat dilihat dari peralatan yang digunakan, waste yang dihasilkan, serta waktu tunggu antar proses. Kinerja industri dilihat dari jam kerja, kedisiplinan pekerja, serta keahlian pekerja. Adapun yang menjadi perumusan masalah pada penelitian ini adalah menganalisa dan meminimalkan waste pada proses produksi U-ditch dengan pendekatan Lean Manufacturing. Waste sendiri didefinisikan sebagai segala aktivitas kerja yang tidak memberikan nilai tambah dalam proses transformasi input menjadi output sepanjang value stream. Berdasarkan hasil penelitian, didapatkan jenis pemborosan yang paling sering terjadi adalah waiting (21.30%), defective parts (18.34%), dan movement (17.75%). Mapping tools yang digunakan berdasarkan hasil konversi skor kuisioner ke dalam matriks VALSAT adalah Process Activity Mapping (42.00%) dan Supply Chain Response Matrix (20.21%). Dari process activity mapping dapat diketahui bahwa proporsi waktu aktivitas tranportation sebesar 26.84 %, aktivitas ini termasuk aktivitas necessary non added value. Setelah perbaikan, dilakukan proporsi waktu aktivitas tranportation menjadi 11.58 %. Untuk nilai Value Added Ratio (VAR) sebelum perbaikan sebesar 49.13% setelah penerapan perbaikan nilai VAR menjadi 52.87%. ============================================================ In the industrial world a lot of competition occur to meet the needs of consumers. The competition includes the products, production processes and the performance of the industry. The product is the result of a production in defects of product. For the production process can be seen from the equipment used, waste produced, and the waiting time between processes. Industry performance can be seen from hours worked, labor discipline, and the expertise of workers. The problems in this research are to analyze and minimize waste in production processes U-ditch using Lean Manufacturing approach. Waste is defined as any work activities that do not provide value added in the process of transforming inputs into outputs throughout the value stream. Based on this research, they were found that the most frequent types of waste occurs is waiting (21.30%), defective parts (18.34%), and movement (17.75%). Mapping tools used by the results of the questionnaire scores conversion into VALSAT matrix is Process Activity Mapping (42.00%) and Supply Chain Response Matrix (20.21%). From process mapping activity can be seen that the proportion of time of 26.84 % transportation activity, this activity includes necessary non-added value activities. After the repair, do the proportion of time transportation activity becomes 11.58 %. For Value Added Ratio (VAR) before an improvement of 49.13% after the application of the VAR value improvement to 52.87%.
