Abstract

agar extraction

micro and macromineral

growth hormones

solid waste

The identification and characterization of chemical composition of solid agar extracted solid waste were carried out. The method used was to take samples randomly in several seaweed processing industries to analyze their chemical composition. The parameters tested included the micro-nutrient and macro-nutrient content, growth-stimulating hormone level, and ash contents. The results showed that solid waste from agar extraction consist of micronutrients such as: Cu (4.80 ppm), Fe (0.24 ppm), Zn (8.42 ppm), Mn (57.58 ppm), B (32.32 ppm) as well as the macronutrients such as: N (0.20%), P (0.12%), K (0.17%), C-organic (10.96%), Na (0.66%), Ca (0.61%), Mg (0.09%), CEC (13.5 me/100g), and N/C ratio of 54:7. Growth hormones auxins (191 ppm), gibberellin / GA3 (509.5 ppm), cytokinin-kinetin (244.5 ppm) and cytokinin-zeatin (70.5 ppm). The ash content was 60.19%, a slightly acidic pH of 6.3, diluted in cold water (11.67%) and hot water (23.17%) as well as in 1% sodium hydroxide solution (35.32%). Based on the results of identification and characterization, the solid waste of agar extraction was useful as a raw material for plant fertilizer.
