Abstract

Research aimed to evaluate the ability of kalbar biofertilizer to improve productivity of soybean. Experiment was conducted in the field experimental plot of Cibinong Science Centre. Soybean (Glycine max) var Baluran was treated with a series of fertilizer i.e.: compost containing Nitrogen fixing microbes, compost containing Phosphate solubilizing microbes, compost containing lignocelullosic degrading fungus, Kalbar biofertilizer (compost containing Nitrogen fixing, Phosphate solubilizing and lignocellulosic degrading microbes), chemist fertilizer, compost and control. The height of plant, fresh weight of biomass, number of leaves, pod number, and weight of seed were observed. The Nitrogen, Phosphate and Carbon which exist on the soil observed before planting, while flowering and while harvesting. The result was the application of kalbar biofertilizer able to increase the Carbon (C), Nitrogen (N) and Phosphor (P) content in the soil. This treatment also increased the fresh weight of biomass (22%), the number of pods (11, 11%) and the weight of seed (12,22%).

Abstract

A study on the effect of Marasmius  pulcheripes J8 and soil fungi interaction on the activity and ability of laccase to degrade palm oil mill effluent (POME) was previously conducted, and some Basidiomycetes fungi were identified capable. Therefore, the aim of this study was to determine the ability of Marasmius pulcheripes J8 to degrade POME in the presence of inducers, and interactions with soil fungi. Furthermore, 3 types of inducers were applied to elevate its laccase activity, which include CuSO4, sucrose and Ammonium tartrate. In addition, M. pulcheripes J8 was grown together with soil fungi, encompassing Aspergilus niger NK and Penicillium sp R 75, in order to boost the action. The results showed the highest laccase activity was in M. pulcheripes J8 pure culture on a PDB medium of 3566.04 U / mL.  Moreover, the POME decolorization was up to 74.25% after 20 days of incubation, and reduced COD level was 81%. Meanwhile, the addition of an inducer has never been performed before, and the outcome of this investigation showed the ability of M. pulcheripes J8 to degrade POME, and decrease environmental pollution. POME waste treatment using fungi is more affordable than other methods.

Abstract

Some species of Basidiomycetes, specifically white rot groups, produce three ligninolytic enzymes, namely, Lignin Peroxidase (LiP), Manganese Peroxidase (MnP) and Laccase (Lac), which have low activity in degrading Palm Oil Mill Effluent (POME). The research objective was to obtain the data on the ability of the Coltricia cinnamomea to produce LiP, MnP, and Lac enzymes to degrade POME. This research also studied the effect of sucrose, alcohol, veratryl alcohol, CuSO4 and ZnSO4,as inducers. Isolates of Coltricia cinnamomea, which were stored in a PDA media at -20℃ were obtained from the Microbiology section of the Research Center for Biology (LIPI). Furthermore, the growth media used were DM, Bean sprout Extract (TE) and PDB. The result indicated that PDB is the most suitable growth media for the production of ligninolytic enzymes, because in this medium these enzymes showed the highest activity. It was also observed that sucrose increased the laccase activity by 40.80%. Furthermore, Coltricia cinnamomea was able to reduce the concentration of Poly R-478 by 60.74%, after the addition of ZnSO4. In addition, it degraded and decreased the color and COD of POME, by 72.63% and 91.19% respectively, after the addition of veratryl alcohol, and incubation for 10 days. Therefore, this fungus can be used to degrade POME in order to prevent environmental pollution. Coltricia cinnamomea has not been used for POME degradation. By using Coltricia cinnamomea, we  obtained new data regarding the activity of laccase and its ability to degrade POME.

Abstract

The presence of local floral resources as forage is essential, especially for the farm survival in anticipaty the impact of the global climate change. The availability of forage in the dry land ecosystems depends on water supply. However, the climate change has caused the change on rainfall pattern including the initiation of the dry season. The problem should be anticipated by the local farmers’ readiness in providing sufficient feed and their ability in performing the excellent management during all seasons. In some areas of East Bali and Nusa Tenggara (West andEast), dry climate crisis 2004 led to feed scarcity. Therefore, this study was conducted in order to identify the potential forage resources in the arid land. The discussion is focused on the results of survey and secondary data collection. Based on the results, there were 22 plants that could be used as forage which were abundant during rainy season, whereas 15 others were able to be forage and silage during the transitional season and along the dry season. The results also showed that the introduction of silage fermentation technique was required as the way to preserve feed for the supply during the dry season. In this study the role of polymer compounds hydrolyzing microbes and the fermentation process by the GRAS (Generally Recognized as Safe) microbes preceeded the role of Lactobacillus plantarum were observed. The results of this study may become a reference in anticipating the global climate change impacts in dry land areas by the application of functional microbial technology in small local farms’ feed management activities.(Key words: Local floral resources, Dry land climate, Fermented feed, Lactobacillus plantarum)
