Operator Workload Analysis on Trailer Operation Using Two Wheel Tractor With Cage Wheel in Palm Oil Soil

Abstract

The operation of the pivot trailer on flat land is more ergonomic than conventional trailers, but on sloping land it has never been tested. The operation of the two-wheeled tractor carried out by the operator on uneven land has problems with the steering handlebar which goes up and down following the movement of the tractor body, thus affecting the increase in workload. To reduce the excessive workload, it is necessary to design a trailer that can be controlled easily. The purpose of this study was to analyze ergonomics, especially the operator's workload when operating a pivot trailer and conventional trailer on a two-wheel tractor using cage wheels. The trailer is towed on a tractor with treatment on sloping land and flat land with several turns, and data collection of the operator's workload uses the heart rate method. The results showed that the operation of the pivot trailer for sloping land (0°, 10°, and 30°) respectively showed IRHR values of 1.13, 1.15, and 1.46 or work levels of "Light", "Light”, and “Medium”. When using a conventional trailer, the IRHR values are 1.12, 1.12, and 1.39 or work levels of “Light”, “Light” and “Medium”. The average energy consumption rate for operating a pivot type trailer is 2.80 kcal/hour.kg-bb (kilocalories per hour per operator weight), while using a conventional trailer is 2.75 kcal/hour.kg-bb. The level of operator workload is also influenced by skills in driving.

Workload analysis on the operation of a type II pivot trailer on a hand tractor using tire wheels in oil palm plantations

“…When compared with the research of Idkham et.al. [5] in the operation of the pivot type trailer before modification in oil palm using cage wheels, it was found that the WEC values were 1.55, 1.57, and 2.03 kcal/minute for land slope 0º, 10º, and 30º, respectively. The level of qualitative workload is indicated by the IRHR value, which indicates how heavy or light a job is felt by a person.…”

Analisis beban kerja operator pada pengoperasian trailer pivot II menggunakan traktor roda dua dengan roda besi termodifikasi di lahan miring

“…Pengujian sistem penggandengan trailer pivot pada traktor roda dua di lahan miring perkebunan kelapa sawit ini masih memiliki beberapa kelemahan, diantaranya yaitu tempat duduk operator yang belum bisa menyesuaikan dengan setiap operator dan tidak ada sistem pengereman yang akan mengakibatkan trailer tidak dapat berbelok dengan sempurna pada saat pengoperasian di lahan miring, begitu pula dengan penggunaan roda traktor yang dapat menyesuaikan dengan berbagai lahan miring dan tidak menyebabkan kesulitan pada saat penggangkutan hasil panen Tandan Buah Segar (TBS) [5].…”

“…Gambar 4. Grafik TEC dan TEC' [4] Jika dibandingkan dengan penelitian Idkham, et al [5], mengenai analisis beban kerja operator pada pengoperasian trailer pivot menggunakan traktor dengan roda sangkar. Hasil analisis kualitatif dan kuantitatif diperoleh ketika pengoperasian rata-rata nilai IRHR di lahan datar adalah 1,13, pada lahan miring 10° diperoleh nilai 1,15, dan pada lahan miring 30° nilai rata-rata yaitu 1,46, sehingga dengan dilihat pada acuan tabel kategori pekerjaan di lahan datar dan miring 10° adalah "Ringan", dan pada lahan miring 30° yaitu "Sedang".…”
