Abstract

An exessive use of inorganic fertilizers in agriculture cultivation system causes many disadventages, such as increase cost production, reduce farmer’s income and soil fertility, and harm our environment. Therefore, it is needed to find out raw materials for development of organic biostimulant and biofertilizer inducing essential element absorption, growth and yield of plants, which are adaptive to our environment as well. Previous researchres reported that seaweed contained plant growth hormones and essential elements in liquid and solid extracts respectively. This article reports effect of solid and liquid extracts of Sargassum cristafolium on growth and yield of rice plants. The extracts were extracted according to modified procedure.. Solid extract (350 gr) of Sargassum cristafolium was mixed with soil (6650 gr) to become 7 kg soil media. Moreover, liquid extract (10%) of Sargassum cristafolium was sprayed to rice plants once a week during vegetative growth. The results shown that addition of 350 gr of solid extract to soil media increased growth (plant high, tiller number, shoot dry weight and root dry weight) and yield (penicle number and grain weight per plants) significantly compared with those of plants which were not supplied with solid extract. However, spraying liquid extract of Sargassum cristafolium did not affet significantly growth and yield of rice plants, even small change happen in growth and yield parameters of the rice plants supplied with solid extract. This indicates that solid extract is a potential source for development of biofertilizer which is adaptive to our environment to support sustainable agriculture system.

Abstract

Rumput laut yang dikenal dengan nama ilmiah makroalga merupakan salah satu komoditi bernilai ekonomi tinggi karena kandungan senyawa hidrokoloid seperti karaginan dan agar. Rendahnya kadar senyawa hidrokoloid yang dihasilkan rumput laut menyebabkan rendahnya harga jual komoditi tersebut. Sistim teknologi budidaya yang digunakan menentukan kualitas rumput laut yang dihasilkan. Artikel ini melaporkan diseminasi teknologi budidaya Eucheuma cottonii dan Eucheuma striatum sistim rakit apung dan long line kepada pembudidaya rumput laut di Teluk Ekas Lombok Timur untuk memacu peningkatan hasil rumput laut baik secara kuantitas maupun kualitas. Diseminasi teknologi dengan dua metode tanam, rakit apung dan long line, dilakukan bersama pembudidaya rumput laut di Teluk Ekas. Diseminasi teknologi yang dibarengi dengan praktek langsung, dapat melihat langsung hasil yang diperoleh dengan penerapan telnologi tersebut, yang pada akhirnya pembudidaya rumput laut mudah memahami dan secara sadar dapat meniru teknologi budidaya tersebut pada musim tanam berikutnya. Dengan demikian, diseminasi teknologi tersebut dapat meningkatkan mutu hasil, harga jual, yang pada akhirnya meningkatkan pendapatan pembudidaya
