SISTEM MONITORING GAS OKSIGEN DAN KARBONDIOKSIDA PADA RUANG PENYIMPANAN SISTEM UDARA TERKONTROL
Abstract: One of way in
pickling process of main food material of vegetable and fruits is storage. In principle metabolism
storage, like respiration,
transpiration, infection plant
diseases and lengthen more
durable. Purpose of
storage of fruit
and vegetable to
lengthen product usefulness, controls
request of market
and increases advantage.
At research before
all, the system controlled
atmosphere storage still be done in manual either from within observation of composition
and operation of gas in it. Therefore, need to be done modification of
equipment with addition of monitoring system and gas control automatically, so
that change of gas volume in storage space of CAS can be detected. Equipment
applied in this research is microcontroller AT89S51 and
its arrangement system
by using computer.
With existence of
communications between
microcontroller system with
personal computer through
IC RS 232.
At this research happened change of oxygen gas
concentration from 21% to 2% and increase of percentage of carbondioxide from
0.03% to 2.5% for temperature 26oC. this matter is according to
boundariset wanted for condition of apple atmosphere Rome Beauty.
