| Summary: | Primary industries in Indonesia steadily consume more wood each year, but within
legal bounds, it is impossible for the wood production to meet this demand. Increase of
production Hutan Tanaman Industri (HTI) is required to equalize consumption. Fertilizer
used in planting holds a great influence on HTI growth. Accuracy and consistency of
fertilizer dosage plays an important role of ensuring optimal production and production
speed. Fertilizing mechanization becomes one of the solution alternatives as current process
is done manually. Sinarmas Forestry (SMF) propose to collaborate with ITB to design a
fertilizer distributor system (fertilizer applicator) which capable to give fertilizer with
accurate and variable dosage. Automation of the applicator is designed in this study, while
mechanical design is done in related study.
The designed applicator uses auger feeder concept, mass distribution is done by a
combination of controlled auger movement and mass metering system. Mass measurement
is done by measuring strain of cantilever shaft using strain gauges.
Analysis result shows largest theoretical mass error is ±0,846gram with applicable
dosage variation 30-85gram. Working procedures of the applicator and the electrical wiring
diagram is explained in the text. |
