Abstract

PT X is a company that works in the plantation sector, one of which is an orange plantation. In the process of harvesting lime leaves, there are 3 workstations and 4 work activities. Most of the work is done manually with a high workload and repetitive movements, causing musculoskeletal complaints. Workers complain of musculoskeletal disorders while working. During initial observation, there were complaints of pain in the neck, shoulders, arms, waist, thighs, and knees. Based on these problems, this study aims to analyze the factors that cause musculoskeletal disorders in the orange harvesting process. The method used to solve problems with partners is by using an ergonomic checklist and the PATH method to analyze three physical risk factors in the workplace. Based on the results of data processing using the PATH method, it was found that the biggest risk factors for injury were 45.53% soil hoeing, 42.39% harvesting and 12.08% grass cutting. The proposed improvements given after being analyzed using ergonomic checkpoints are: (1) reducing bending or squatting postures; and (2) providing protectors and covers for lawn mowers and handcarts and handles for tools for harvesting oranges. This proposed improvement is in accordance with Sustainable Development Goals number 3, namely Good Health and Wellbeing for all.

Abstract

PT. XYZ is one of some cigarette companies in Indonesia. In producing cigarette, the firm requires a material named “etiket” which is produced by printing division for internal consumers of PT. XYZ. merupakan salah satu dari beberapa produsen rokok di Indonesia yang telah dikenal masyarakat. In order to produce “etiket”, there are some wastes occurred. One of wastes occurred in printing division is product defects. This paper attempts to identify wastes in the division of printing using Lean Manufacturing approach by applying Value Stream Mapping (VSM) method. The results from Cause Root analysis found that the problems caused the defects in production process. It shows that the most wastes occurs in the printing division are product defect and waiting time. The product defects are caused because there is no standard applied in processing the product and poor inspections by management, while the causes of waiting time wastes is because of lack of carrier and no standard in each process. The recommendation can be suggested to the company are adding some carrier (product’s transporter), creating process standard in each process. Keywords : Lean Manufacturing, Value Stream Mapping, Value Stream Analysis.

Abstract

Penjadwalan bagi perusahaan adalah aspek yang sangat penting, karena penjadwalan merupakan salah satu elemen perencanaan dan pengendalian produksi, sehingga perusahaan dapat mengirim barang sesuai dengan waktu yang telah ditentukan, agar diperoleh waktu total penyelesaian yang minimum. Dalam penelitian ini, penjadwalan menggunakan metode Simulated Annealing (SA) dengan bantuan Matlab diharapkan dapat menghasilkan waktu total penyelesaian (makespan) lebih cepat dari penjadwalan yang ada pada perusahaan. Metode SA mensimulasikan proses annealing pada pembuatan materi yang terdiri dari butiran Kristal atau logam. Tujuan dari proses ini adalah menghasilkan struktur kristal yang baik dengan menggunakan energi seminimal mungkin. Permasalahan yang dihadapi oleh perusahaan adalah perusahaan belum mempertimbangkan makespan dalam penyelesaian produk dan penjadwalan produksi untuk produk paket satu rumah kos-kosan. Hal ini berdasarkan data produksi yang terjadi keterlambatan dilihat dari waktu penyelesaian (makespan) produksi, sehingga perusahaan harus menambah 2-5 hari lagi untuk bisa menyelesaikan keseluruhan produk. Dengan menggunakan metode SA menghasilkan makespan 23 jam, lebih cepat 2 jam dari pada penjadwalan awal. Kata kunci : penjadwalan, job shop, simulated annealing, idle time, makespan.
