Vehicle Routing Problem (VRP) is the problem for finding optimal routes in the distribution system, and this problem needs attention because it can improve distribution performance. One of the problems in VRP is the Vehicle Routing Problem for Perishable Goods (VRPfPG). This issue addresses VRP for products that are rapidly losing quality and perishable. This paper attempts to review the Vehicle Routing Problem for Perishable Goods (VRPfPG). A systematic review has been carried out on fifty-nine (59) published papers from 2001 to March 2020. The optimization methods in this review were classified into single and multi-objective problems. In addition, the review was also conducted based on the objective function. The results show the metaheuristic algorithm to be a popular optimization method for solving single and multi-objective problems. Further, the results also show that minimizing the total cost distribution to be the objective function that was often used by researchers. Finally, future studies are suggested to explore a more comprehensive investigation in the VRPfPG.

PendahuluanErgonomi didefinisikan sebagai studi tentang aspek manusia dalam lingkungan kerjanya yang ditinjau secara anatomi, fisiologi, psikologi, engineering, manajemen dan perancangan dan desain. Ergonomi berkenaan pula dengan optimasi, efisiensi, kesehatan, keselamatan dan kenyamanan manusia di tempat kerja, di rumah, dan tempat rekreasi [1]. Musculoskeletal Disorders merupakan salah satu cedera yang sering dialami pekerja dalam melakukan kegiatan Manual Material Handling (MMH) yaitu cedera pada otot, urat syaraf, urat daging, tulang, persendian tulang, tulang rawan yang disebabkan oleh aktivitas kerja. Ketika seseorang bekerja pada posisi berdiri atau duduk, pergerakan bagian tulang belakang, terutama bagian pinggang yang rentan dengan gerakan ekstrim yang dapat menyebabkan cedera [2].Susihono [3] menjelaskan bahwa postur tubuh merupakan titik penentu dalam menganalisa keefektifan dari suatu pekerjaan. Apabila postur tubuh dalam bekerja
