Abstract

Biduri fiber (Calotropis gigantea) is a natural hollow fiber with hydrophobic and oleophilic properties potentially used as oil spilled sorbent from seawater. This study aims to determine the absorption capacity and efficiency of the Biduri fiber and membrane to fuel oil. Measurement of oil absorption to seawater was carried out at various fiber weights (0.5-1.5 g), fiber composition (50-95%), contact time (10-90 minutes), temperature (30 and 50°C), and compared with commercial products. The results showed that the fiber weight variation of 0.5-1.5 g has an average absorption efficiency of 96.67%, and the highest absorption was obtained in a weight of 0.5 g, a density of 0.0143 g/cm3, 43.79 g/g. In the membrane composition of 50-95%, the absorption efficiency of 96.98%, and the highest absorption capacity of the membranes was 95%, density of 0.0259 g/cm3 and 44.62 g/g. The absorption capacity and efficiency of Biduri fiber and membrane are higher than commercial products.

Abstract

Biduri (Calotropis gigantea) was a plant with several benefits, namely as a medicinal plant and textile material. Biduri was a wild plant that could grow in various types of soil conditions. The existence of biduri was still not fully utilized by many people. So it was necessary to develop the cultivation technology of Biduri to take advantage of this plant. This research was conducted at the field laboratory of Jumantono, Faculty of Agriculture, Universitas Sebelas Maret, Karanganyar, and used a factorial Randomized Complete Block Design (RCBD), which consisted of 2 factors, namely organic liquid fertilizer from livestock waste and mycorrhizae. Livestock waste liquid fertilizer consists of 40ml/kg soil cow urine, 40ml/kg soil goat urine, 40ml/kg soil rabbit urine, and 40ml/kg soil fish waste. Mycorrhizae consisted of 0 grams/plant, 5 grams/plant, 10gram/plant, and 15gram/plant. There were 20 treatment combinations repeated 3 times, so the total was 60 treatment combinations. The interaction between livestock waste liquid fertilizer and mycorrhizae did not significantly affect all the physiological observation variables. The results showed that the application of livestock waste liquid fertilizer had no significant effect on all observations of physiological variables. Giving mycorrhizae shows that it can increase the number of stomata and the width of stomata aperture.
