| Summary: | Cassava storage has been done by farmers today can only maintain the
quality of the product for 5-7 days.This study aimed to assess changes in quality
parameters during storage of cassava on a wide variety of pile on the ground,
especially in temperature and humidity.
This research was done by storing cassava with a hole in the ground. The
hole size is 40x40 cm width and 50 cm depth. Variations pile of cassava in the
ground that is 2 stacks with an average total weight is 4.2 kg, 3 stack with a total
average weight is 6.3 kg and 4 stacks with a total average weight was 8.4 kg. Each
stack is coated by a layer of dry sand and straw. Parameters observed in this study
were weight losses, moisture content, texture, chemical composition and physical
appearance of cassava. Collecting data is start on the 18th day of storage. This
data collected every 3 days until 24 days, then collected every 5 days until the last
sample.
Storage cassava in the ground with a pile thickness variation can extend
the shelf life of cassava to 39 days. Storage with 2 stacks have the best value
compared to other treatments. Based on the analysis of data on treatment with 2
stacks variation that has been done can be seen the value of k decreased moisture
content (ka) = 0.0078% / day, weight losses (kb) = 0.0207 g / day and the texture
(kk) = 0,0196 kg / day. Statistical analysis showed that there is not significanly
different between treatment for all parameters. However the result for all variation
that was done was significanly different with the control. Changes in chemical
composition such as carbohydrates, ash, crude fiber, protein, fat and energy tend
to decrease during the storage process.
