Abstract

Indonesia is a high tourism sector country which provides opportunities for tour and travel service business. Thereby increasing the growth rate of accidents by 3.3%, one of which was caused by buses. Hafizh 58 Jaya, a company in the field of tourism services, had many complaints against drivers about the problem of muscle disorders due to the lack of ergonomic position of the driver or the seat used which was not suitable with the user or not ergonomic. To analyse this problem, IDEAS framework was applied. This method could describe overall minibus driver movement and produce designs that were appropriate with the level of risk on small musculoskeletal disorders. By normal driving activity, the second driver had the largest PEI parameter index value, 2,186. It was categorized as medium to low-risk musculoskeletal disorders. This meant that the actual chair with normal driving activity was not optimal and not ergonomic. The final design of the redesign chair has given optimal and ergonomic results shown by highest PEI index parameter value of 1,336. This PEI index parameter was categorized at the low risk of musculoskeletal disorders.

Abstract

The development of coffee shop is increasing whether in Europe or Asia. The system in coffee shop are need to be improved as the human mobile are getting higher and people has no more time in waiting. The demand of consumer about coffee shop system is getting wider so that a system in it are need to be discuss. Cognitive Work Analysis (CWA) is expected to outline parts in the system so that it can be extracted to analyze and evaluate the existing system. This tools is a method to analyze industrial complex system which is useful for industrial design. CWA are extracted into five phase which has different aims in each phase. The result of this research are produces seven function and five situation in control task analysis. In collecting the data, this research use brainstorming as qualitative method and found out four categories in WDA, seven categories in CTA, nine categories in WCA. The coffee shop system are need to be improved as the human mobile are getting higher and people has no more time in waiting. The customer demand about coffee shop system is getting vary so that an improvement are need to be discuss. Cognitive Work Analysis is expected to outline parts in the system so that it can be extracted to analyze and evaluate the existing system. This tools is a method to analyze industrial complex system which is useful for industrial design. The result of this research are produces seven function and five situation in control task analysis

Abstract

Industri manufaktur mengolah bahan baku menjadi produk setengah jadi atau jadi. Penelitian ini menyoroti mesin rip kayu yang sering menjadi penyebab kecelakaan kerja. Hasil studi lapangan menunjukkan bahwa banyak karyawan tidak mematuhi SOP, sehingga analisis K3 sangat diperlukan. Penelitian ini menggunakan metode Delphi dan HFACS untuk menentukan potensi bahaya kecelakaan kerja dan usulan perbaikan menggunakan 5W+1H untuk mengetahui penyebab utama terjadinya kecelakaan kerja mesin rip kayu, sehingga dapat melakukan perbaikan yang lebih efektif dan efisien. Hasil menunjukkan dua potensi bahaya utama: kesadaran karyawan yang tidak memilih bahan sesuai dan keluhan kesehatan karyawan. Analisis HFACS menemukan bahwa human factors pada kecelakaan berulang berada pada tahapan organisasi. Kegagalan tertinggi ditemukan pada proses organisasi, seperti visi dan misi, kebijakan, struktur, dan budaya K3 yang tidak efektif. Hasil usulan perbaikan menunjukkan bahwa kegagalan paling berpengaruh melibatkan karyawan, manajer operasional, dan manajer produksi.
