Abstract

Salah satu aktivitas yang dilakukan pada PT. XYZ yaitu pengambilan sampel water treatment sebanyak 25 sample point dengan jarak yang berjauhan serta berat masing-masing sampel 1Kg. Pengambilan sampel dilakukan dengan menggunakan wadah yang diangkat secara manual dengan total berat sampel 25kg. Pekerja kerap mengeluh sakit pada bagian lengan atas sampai bahu. Penelitian ini dilakukan untuk mengetahui batas maksimal beban yang dapat diangkat oleh pekerja dengan melakukan analisis Recommended Weight Limit (RWL) dan Lifting Index (LI) serta memberi solusi agar pekerjaan lebih efisien. Hasil perhitungan diketahui berat beban yang diangkat melebihi batas pengangkatan yang direkomendasikan dikarenakan nilai LI>1 dan dengan bobot RWL maksimal 10.90Kg, aktivitas pekerja tersebut berisiko cidera tulang belakang. Berdasarkan diskusi dengan pihak perusahaan diperlukan alat bantu material handling berupa troli, dimensi troli usulan yaitu (a) lebar alas troli adalah 35 cm; (b) panjang alas troli adalah 80 cm; (c) tinggi troli 54,47 cm; (d) lebar pegangan troli 35,19 cm; (e) tinggi pegangan troli 95,16 cm.

Abstract

PT ISM Tbk. Divisi Bogasari merupakan perusahaan manufaktur makanan yang memproduksi tepung terigu. Salah satu proses produksi perusahaan tersebut yaitu packaging tepung terigu 25 Kg. Dalam proses packaging yang dilakukan terdapat 4 CTQ (Critical To Quality) diantaranya yaitu kondisi label, kondisi jahit, keadaan metal detector, dan berat timbang. Selama periode Agustus-November 2023 proporsi kecacatan produk sebesar 4.01% yang artinya melebihi standar maksimal kecacatan perusahaan sebesar 2.5%. Penelitian ini dilakukan untuk mengurangi kecacatan produksi dengan metode six sigma serta mengetahui solusinya dengan prioritas tindak perbaikan yang dilakukan dengan metode FMEA. Hasil analisis diketahui nilai sigma pada proses packaging sebesar 3.84, cacat jahit merupakan jenis kecacatan yang mendominasi dengan persentase cacat sebesar 52.8%. Faktor utama yang menyebabkan yaitu kelelahan pekerja. Solusi tindak perbaikan yang dapat dilakukan yaitu penyesuaian area kerja agar tidak panas dan bising, melakukan training dan pendampingan bagi operator baru, penyesuian job desk kerja, dan penyesuaian fasilitas kerja selama overtime.

Abstract

Competition in the Temulawak Unowen MSME industry is getting tighter. Many other producers are also trying to enter the market with various new innovations both in terms of taste and packaging. Therefore, it is important for companies to continue to carry out product development in order to remain competitive and maintain their market share. In this study, the Kano and QFD methods were used. The purpose of the Kano Method is to find out what consumers want about cracker production, and QFD is to offer the most important suggestions for improving quality. The results showed that Kano has 12 one-dimensional attributes, 4 Indifferent attributes. On the other hand, the QFD research results show that the validity testing of all three tiers resulted in a calculated R value that is more than R table 0.55, which indicates that the attributes are valid while the reliability test shows that the alpha value of all 3 tiers is 0.663 and the respondents' answers are considered reliable.

Abstract

PT Ravana Jaya is a general contractor that works on steel fabrication and has several partners from small, medium, and large scale companies.  Observations show that errors often occur during the production process, leading to a number of defective products with a defect percentage of 0.12%. The allowable defect percentage ranges between 0.05% and 0.07%, or approximately 1-2 items per month.  Therefore, research should be conducted to look at the human errors that cause defective products during the production process.  This study utilized the Human Error Assessment and Reduction Technique (HEART) and Systematic Error Reduction and Prediction (SHERPA) methods.  According to this study, the highest predicted human error occurred in the welding task with a HEP value of 10.565, and the lowest human error occurred in the welding task with a HEP value of 10.565. To reduce the number of defective products, it is recommended to make improvements, such as conducting strict and regular evaluation and supervision, continuous training, adding dividers between parts, and changes in design.

Abstract

PT. Ravana Jaya is a general contractor working on steel fabrication and has several partners from small, medium, and large scale companies. Observations showed that workers reported complaints related to pain in several parts of the body in the upper neck, lower neck, back, and left and right shoulders with a percentage value of 85% in the location of pain complaints in the upper neck area. This research uses the RULA (Rapid Upper Limb Assessment) and REBA (Rapid Entire Body Assessment) methods. The results of the RULA and REBA scores in the punching process are 7 and 9 with a high risk category so that it is necessary to hold a work posture improvement solution by adjusting the height of the workstation and using an adjustable bench, using ergonomic tools such as drilling machines and material support tools to reduce physical loads, job rotation and regular breaks to prevent muscle fatigue. These improvements are not only beneficial for the health and well-being of workers, but also for the sustainability of company operations.
