TEKNOLOGI HIDROPONIK SISTEM SUMBU PADA PRODUKSI SELADA LOLLO ROSSA (Lactuca sativa L.) DENGAN PENAMBAHAN CaCl2 SEBAGAI NUTRISI HIDROPONIK
ABSTRACT: Calcium in one of
the important minerals that are needed by human body as much as 1200 mg calciums/
day/ person. Every day humans consume calcium as much as 254 mg/ day/ person
and it causes people suffering ostheoporosis and other growth disorders.
Therefore human needs toconsume the source of calcium, one of them is
vegetables. Vegetables in one of the source of calciumthat is cheap, obtainable
and consumable. Lettuce (Lactuca sativa L.) is one of the vegetable with high
caclsium but development of lettuce cultivation is still limited.. The efford
to increase thequantity and quality of lettuce production can be done with
hydroponics technology. Hydroponicstechnology enables efficient lettuce
cultivation. The innovation adding of CaCl2 concentration in hydroponic
nutrients is expected to increase the lettuce production. The purpose of this
research was to determine the concentration of CaCl2 on the hydroponic
nutrients of wick system on the productionof Lollo Rossa lettuce (Lactuca
sativa L.). The research was conducted at the Green House, Faculty of
Agriculture, University of Jember, started in August to Noverber 2016. The
research used Completely Randomized Design (CRD) with single factor, which was concentration
of CaCl2 on thehydroponic nutrients (C) and it be combined with Lollo Rossa
varieties of lettuce (Lactuca sativa L.) (S) with three replications. The best
concentration of CaCl2 for Lollo Rossa production was 650 ppm
