Abstrak. Wheelbarrow adalah salah satu alat angkut material yaitu gerobak sorong, wheelbarrow pada awalnya merupakan alat angkut yang sangat berguna bagi masyarakat yang melakukan aktivitas pengangkutan hasil perkebunan ataupun juga barang-barang bangunan yang lain sebagainya, jika dilihat dari definisinya wheelbarrow adalah alat angkut yang didorong dengan tangan, memiliki 1 buah roda, dan didorong oleh satu orang operator melalui handle. Sejalan dengan hal tersebut telah banyak pengembangan-pengembangan yang dilakukan terhadap sistem dan metode penunjang untuk mempermudah semua aktivitas tersebut. Salah satunya alat bantu angkut meterial yaitu gerobak sorong (wheelbarrow). Gerobak sorong atau wheelbarrow pada awalnya merupakan alat angkut yang sangat berguna bagi masyarakat untuk melakukan aktivitas pengangkutan hasil perkebunan ataupun juga barang-barang bangunan dan lain sebagainya,  Hasil perhitungan persentil yang dilakukan didapat panjang 29,02 cm dengan pembulatan menjadi 30 cm. jadi, panjang hendle perancangan yang ergonomis berdasarkan antropometri pekerja kebun kelapa sawit adalah sebesar 30 cm, dihitung dari titik las, diameter handle wheelbarrow sebesar 3,03 cm, dan lebar hendle 9,04 cm dengan pembulatan menjadi 9 cm. Hasil penelitian setelah dilakukan perancangan ulang Wheelbarrow yang berbasis Quality Function Deployment (QFD) adalah memiliki aspek-aspek quality, ergonomi yang lengkap yaitu efektif, nyaman, aman, sehat, dan efisien (ENASE). Keluhan muskuloskeletal karyawan Perkebunan mengalami penurunan sebesar  31,79%. Design Handle Wheelbarrow to Reduce Musculoskeletal Complaints Method Using Quality Function Deployment (QFD) in Oil Palm Plantation Bagan Jaya District, Indragiri Hilir, RiauAbstract. Wheelbarrow is one means of conveyance of material, namely a wheelbarrow, wheelbarrow initially a conveyance which is very useful for people who transport activity plantation crops or also goods buildings, etc., when seen from the definition wheelbarrow is a means of transport that is driven by hand , has 1 piece wheels, and driven by an operator through the handle. In line with this has been a lot of developments done on the system and methods of support to facilitate all those activities. One of these tools is the wheelbarrow transport meterial (wheelbarrow). Handcart or wheelbarrow to haul awalnyamerupakan a very useful tool for people to do activities or also the transportation of farm goods and other buildings, performed percentile calculation result obtained by rounding length of 29.02 cm to 30 cm. so long hendle ergonomic design based anthropometric oil palm plantation workers is 30 cm, calculated from the point of welding, wheelbarrow hendle diameter of 3.03 cm, and width hendle 9, 04 cm with rounding to 9 cm. Results of the study after the redesign Wheelbarrow based Quality Function Deployment (QFD) is to have the aspects of quality, ergonomics complete that is effective, convenient, safe, healthy, and efficient (ENASE). Musculoskeletal complaints plantation employees decreased by 31.79%.

Basal stem rot, one of the most important diseases of oil palm in Southeast Asia, has also been identified in Colombia. The increase in disease incidence in the last decade has attracted the attention of producers and researchers. In the search for a procedure that allows for the early identification of diseased palm, Cenipalma evaluated the use of electrical impedance tomography to identify the different stages of development of basal stem rot. The tomograms were compared with transversal sections of healthy and diseased oil palm trees. Following Cenipalma’s preliminary studies on early diagnosis of basal stem rot with tomography, the present study improved upon the technique by analyzing the tomograms of 209 diseased palm trees (confirmed by symptomatology), 346 asymptomatic palm trees, and 132 healthy palm trees. The minimum and maximum electric impedance values as well as the ratio between these values was recorded. The range of 1 to 95 Ω was used to represent the internal damage. The ratios averaged 5.1 for diseased, 1.9 for asymptomatic, and 1.5 for healthy palm trees. With the range and the ratio criteria established, it was possible to identify the disease in 100% of asymptomatic sampled palm trees. This study demonstrated that electrical impedance tomography is a powerful tool for early detection of basal stem rot, which can be used to establish an early disease management program.
