UJI PERFORMANSI GETARAN MEKANIS DAN KEBISINGAN MIST BLOWER YANMAR MK 150-B
Abstract: Mist blower is one
of the mechanization tool of agriculture considered as a tool that can assist
humans in fertilizer and pesticides spreading activities. Levels of motor speed
in the used mist blower were 1915, 4009, and 7227 rpm. Vibration measurements
were conducted on the engine and handlebar control mist blower with the
three-dimensional axes namely X, Y, and Z. Mist blower noise measurements were
performed on the engine, operator's right ear and left ear. Based on the
analysis of vibration and noise from the mist blower of type MK 150-B was
obtained the safe limit values from the
use of these tools. The safe limit of the use of mist blower in motor rotation
speed of 1915, 4009, and 7227 rpm after being compared with the vibration and
noise were 1 hour, 1 hour and 24 minutes respectively. The farther the distance
from noise source, the lower the noise level too. Moreover objectivity study of
operator was conducted. The first farmer was tired faster than the second
farmer. In terms of age of farmer, the second farmer (60 years) older than the
first farmers (40 years), but this should not affect significantly. Activity on
the previous day greatly affects the level of fatigue when operating the mist
blower. This was because the first farmers did more activities and had rest
periods that less than second farmer.
