Lahan pasir pantai memiliki potensi untuk budidaya tanaman hortikultura, termasuk kubis
(Brassica oleracea L.), meskipun menghadapi kendala seperti salinitas udara dan rendahnya
kesuburan tanah. Penelitian ini bertujuan untuk mengkaji pengaruh salinitas udara dan volume
pembilasan terhadap pertumbuhan, fisiologi, dan hasil tanaman kubis di media tanah pasir pantai.
Penelitian dilaksanakan di screen house Fakultas Pertanian Unsoed menggunakan Rancangan
Acak Kelompok Lengkap (RAKL) dua faktor dengan tiga taraf salinitas udara (0, 12, dan 24
mS/cm) dan tiga taraf volume pembilasan (0, 3,5, dan 7,0 mm), menghasilkan 9 kombinasi
perlakuan. Hasil menunjukkan bahwa salinitas udara menurunkan tinggi tanaman, jumlah daun,
dan kadar klorofil vegetatif secara signifikan. Volume pembilasan mempengaruhi kadar prolin
vegetatif dan bukaan stomata generatif. Interaksi kedua perlakuan berpengaruh nyata hanya pada
nilai kehijauan daun vegetatif. Temuan ini menunjukkan kemampuan adaptif tanaman kubis
terhadap stres salinitas melalui mekanisme fisiologis internal.

Coastal sandy land in Indonesia offer potential for horticultural crop cultivation, including
cabbage (Brassica oleracea L.), but face limitations such as air salinity and poor soil fertility.
This study aimed to examine the effects of air salinity and water flushing volumes on cabbage
growth, physiology, and yield in coastal sandy media. The experiment was conducted in a screen
house at the Faculty of Agriculture, Universitas Jenderal Soedirman, using a Completely
Randomized Block Design with two factors: three air salinity levels (0, 12, and 24 mS/cm) and
three water flushing volumes (0, 3.5, and 7 mm), resulting in 9 treatment combinations. Results
showed that increased air salinity significantly reduced plant height, leaf number, and vegetative
chlorophyll content. Water flushing significantly influenced vegetative proline accumulation and
generative stomatal aperture. Interaction between the treatments significantly affected only
vegetative leaf greenness. These findings suggest that cabbage plants can maintain productivity
under saline stress through internal physiological adjustments.
