Abstract

Penjadwalan tenaga kerja merupakan salah satu permasalahan yang sering dihadapi oleh manajer operasional. Ketidaksesuan dalam penjadwalan tenaga kerja dapat berdampak negatif pada produktivitas, kepuasan pelanggan dan biaya. Hingga sekarang, penelitian berkaitan dengan penjadwalan tenaga kerja telah diteliti secara luas. Sebagian besar penelitian fokus pada beberapa faktor seperti ketersediaan tenaga kerja, kualifikasi pekerja, peramalan permintaan dan biaya, namun sedikit yang mempertimbangkan faktor ergonomi. Oleh karena itu, penelitian ini bertujuan untuk memodelkan penjadwalan tenaga kerja dengan mempertimbangkan faktor-faktor ergonomi, seperti faktor manusia, batasan lingkungan, dan karakteristik tugas kerja. Pertimbangan terhadap ketiga faktor tersebut, dapat berdampak pada peningkatan performansi bisnis keseluruhan serta kesejahteraan pekerja. Penelitian lebih difokuskan pada pekerjaan monoton dan berulang, dimana aktivitas kerja tersebut memiliki risiko stress, kelelahan, kejenuhan, cedera dan dapat berdampak pada performansi pekerja. Penelitian dilakukan melalui tiga tahap utama, (1) identifikasi faktor ergonomi, (2) pembuatan model matematis, dan (3) pengujian numerik. Mixed integer linear programming digunakan untuk menyelesaikan penjadwalan rotasi kerja dengan mempertimbangkan produktivitas sebagai fungsi tujuan. Model akan mempertimbangkan faktor manusia (variabilitas skill, produktivitas, beban kerja dan kelelahan), bahaya lingkungan (kebisingan dan temperatur) dan karakteristik tugas kerja (risiko tugas kerja). Hasil pengujian numerik menunjukkan bahwa penjadwalan tenaga kerja dengan pertimbangan terhadap faktor ergonomi memberikan hasil yang lebih baik, dilihat dari segi kesejahteraan tenaga kerja dan produktivitas pekerja. ============================================================ Workforce scheduling is one problem that have been faced by many operation managers. Inappropriate workforce scheduling could negatively impact productivity, customer satisfaction and cost. Until recently, large number of research has been done to deal this issue. Most of research focused on factors such as workforce availability, qualification, demand forecasting and cost, but limited on on Ergonomics-related-factors. This paper, therefore, aim to model the workforce scheduling problem which incorporating Ergonomics factors including human factor, environmental limitation and job charactheristic. By considering these three factors could potentialy improve business operation performance as well as increase human well-being. This paper will mainly focus on monotonous and repetitive job where worker stress, fatigue, boredom and occupational injuries increase due to the job characteristic and could impact worker performance. This research is conducted through three main stages, (1) identification of ergonomic factors, (2) mathematical modelling and (3) numerical testing. A mixed integer linear programming model is presented to determine job rotation schedules which considers productivity as a objective function. The model will consider human factors (i.e.skill variability, productivity, workload and fatigue), environmental hazards (i.e. noise and temperature) and job characteristic (i.e. the risk of task). The result of numerical testing indicate that workforce scheduling that is consider ergonomics factor give better results in terms of worker well-being for and worker productivity.
