Abstract

Tebu (Saccharum officinarum) merupakan bahan baku penghasil gula digunakan sebagai konsumsi, industri serta sebagai komoditas yang dapat mewujudkan ketahanan pangan di Indonesia. Kebutuhan gula secara nasional mengalami peningkatan, namun tidak diimbangi dengan peningkatan hasil produksi gula secara nasional. Demi mempertahankan dan juga meningkatkan produksi tersebut, diperlukan strategi dalam mengoptimalkan kondisi lahan suboptimal yang dipengaruhi oleh cekaman abiotik salah satunya adalah kadar garam yang tinggi yang biasa disebut salinitas. Efek merusak dari salinitas adalah mengurangi pertumbuhan dan optimalisasi fisiologisnya sehingga mengakibatkan stres pada tanaman. Pada kondisi  tersebut salinitas berdampak pada pertumbuhan dan perkembangan serta bertanggung jawab pada penurunan potensi produksi tanaman. Produksi tebu tergantung pada panjang dan diameter atau dimensi tubuhnya. Salinitas dapat menyebabkan kerugian akibat perubahan dimensi. Salinitas menyebabkan penurunan potensial air dan meningkatkan tekanan osmotik pada tanah sehingga dapat memperlambat tanaman untuk menyerap air dari, akibatnya akan mempengaruhi morfologis dan fisiologis serta biokimia.  Studi pengaruh cekaman stres pada beberapa spesies tanaman dan teknik budidaya pada tebu ini merupakan informasi dasar bertujuan untuk mengetahui serta mengkasji proses penting dalam salinitas sebagai stimultan kondisi garam tinggi, sehingga dapat dijadikan evaluasi dampak morfologi dan fisiologi pada tebu. Studi ini diharapkan dapat memberikan informasi bagi kemajuan riset peningkatan produksi tebu terhadap cekaman garam.

Sugarcane (Saccharum officinarum) is a raw material for producing sugar used for consumption, industry and as a commodity that can achieve food security in Indonesia. National demand for sugar has increased, but is not matched by an increase in national sugar production. In order to maintain and also increase production, a strategy is needed to optimize suboptimal land conditions which are influenced by abiotic streses, one of which is high salt content which is commonly known as salinity. The damaging effect of salinity is to reduce growth and optimize its physiology, resulting in stres on plants. In these conditions salinity has an impact on growth and development and is responsible for reducing the potential for plant production. Sugarcane production depends on the length and diameter or dimensions of the body. Salinity can cause losses due to dimensional changes. Salinity causes a decrease in water potential and increases osmotic pressure in the soil so that it can slow down plants to absorb water from, consequently will affect morphological and physiological as well as biochemical. This study of the effect of stres stres on several plant species and cultivation techniques on sugarcane is basic information aimed at identifying and assessing important processes in salinity as a stimulant for high salt conditions, so that it can be used as an evaluation of the morphological and physiological impacts on sugarcane. This study is expected to provide information for the progress of research on increasing sugarcane production against salt stres.
