Abstract

Cellulose is one of abundance natural biopolymer with limited usage. The common found waste cellulose are waste straw, sawdust, and pineapple pit. Rigidoporus microporus is a white root fungi groups that often attack the roots of plants that rot and die. This study was conducted to assess the ability of white root fungi (R. microporus) to degrade waste cellulose, according to cellulolitic activity index of potential R. microporus isolate. The medium used was Carboxy Methyl Cellulose (CMC) with dye Congo Red (0,1%). The results obtained that R. microporus has cellulotic index 3,23 which indicated as potential cellulose degrade.

Abstract

This study aims to see the effectiveness  of essential oils of leaves, rhizomes and fraction of wild ginger Ellettariopsis slahmong CK Lim against the pathogenic fungus Sclerotium rolfsii which causes rot disease of the stem base of peanut plants an in vitro.The study consisted of two sub activities: (a) inhibited of colony diameter using Patato Dextrosa Agar (PDA) medium and (b) inhibited of colony biomass using Potato dextrose Broth (PDB) medium, the treatments tested were leaf essential oil and rhizome of wild ginger and fractions A1, B2, C3 and D4, with concentration levels (0, 100, 250 and 500 ppm). Experiments (a) and (b) were arranged in the form of a Completely Randomized Design (CRD) in factorial each with 4 replications. The results showed that the leaf essential oil and rhizome of wild ginger and its fractions had the potential to be used as a vegetable fungicide. The A1 fraction has the best antifungal effectiveness compared to the B2 fraction, leaf oil, rhizomes and other fractions, with the highest inhibition of diameter and biomass of S rolfsii colony the 49.47% and 51.46%. Essential oils of leaves and rhizome oil are not statistically significantly different, but in numerically leaf oil are better than rhizome oil. The C3 fraction showed the lowest colony diameter inhibition and biomass of 34.70% and 36.95%. The best concentration level in inhibition the growth of S rolfsii mushroom is 500 ppm, with inhibition of the diameter and biomass of the colony by 81.74% and 84.25%.

Abstract

Dairy manure that functioned as organic fertilizer has potential impact as environmental destructive waste because the absorption of inorganic nutrients in the fertilizer. On the other hand, microalgae growth is hindered by the high cost of culture, whereas organic and inorganic nutrient requirements. Dairy manure have the potential for microalgae nutrients, but are hindered by turbidity levels. Its has been tested for dilution dairy manure and treatments on fluorescence and sunlight sources and the addition of urea commercial fertilizer to absorbs organic and inorganic nutrients. Its prove the integration of bioremediation of dairy manure and microalgae cultivation Chlorella pyrenoidosa and Chlorella vulgaris can be performed and also serves as a source of caratenoid (chlorophyll)
