Abstract

Nutrients (C, N, and P) can affect the growth and biochemical content of Arthrospira platensis. Ethanol can be a potential carbon source compared to glucose and acetic acid. Glycerol is also potential as a carbon source for the growth of Arthrospira platensis. This research was carried out from June to July 2021 at the Aquaculture Laboratory and Experimental Pond Laboratory of the Aquaculture Study Program, Sriwijaya University. The research method used Completely Randomized Design (CRD) factorial with 2 factors consisting of the first factor with 3 treatments and the second factor with 2 treatments and 3 replications. The inoculant was cultured in liquid fertilizer technical F/2 media for culture stock as initial inoculum with a density of ± 1.0 g L-ˡ. Parameters observed were the density, the specific growth rate, and water quality. The results showed that M1S3 treatment had the highest density with a value reaching 4.95 g L-1 and the highest specific growth rate of 0,33% per day. ANOVA test result showed that the addition of carbon sources in the culture media of fertilizer and technical waste had a significant effect (P<0.05) on the growth rate of Arthrospira platensis. The water quality parameters of each treatment were suitable for Arthrospira platensis culture.

Abstract

Today eco-friendly rice farming system becomes interesting agribusiness among farmers, traders and regulators. The use of organic fertilizers as one of eco-friendly components in rice farming system is still low. In some rice production center the farmers of organic rice farming system looks higher than non-organic farmers. The question is: is there any difference among farmers whom use organic, semi-organic and inorganic fertilizers statistically? This research aims to know the difference of rice farmer income (organic and inorganic fertilizer) in East Ogan Komering Ulu (EastOKU), South Sumatra. The method used in this research is comparative analysis (independent t-test). The sample farmers are classified into the three clusters. The research shows that the contribution fertilizer cost from semi-organic farming is higher than full organic and inorganic farming. On the other side, t-test result shows that there is no different income among three kinds of using fertilizer.

Abstract

Lotus is a wild plant in wetlands that have not been widely used but has great potential to be developed as compost tea. Therefore, this research aims to evaluate the content of compost tea made from wild lotus found in wetlands, which has not been sufficiently used but has great potential to be developed as compost tea. It was conducted by testing several methods and compositions of compost immersion, namely A1, A2, A3, and A4 at Aeration 1:5, Aeration 1:10, Non-aeration 1:5, and Non-aeration 1:10, respectively. The results show that the pH value increased until day 8 of immersion and then decreased on days 9 and 10, with a range of 8.0-8.44, in the recommended range. Furthermore, the total dissolved solids in the 1:5 water ratio were lower than the 1:10 of compost and water. The content of nutrients (C-organic, N-total, and P-available), bacteria population, actinomycetes, fungi, and humic acid concentration were higher in aeration treatments for both 1:5 and 1:10 compost and water ratios. In addition, humic acid functional groups in compost tea for all treatments were detected, including OH-phenolic, C=C, C=C, COOH, CH3, secondary amides, and tertiary amides with different wavelengths. Based on these results, it can be concluded that aeration treatment provides better results for the observed variables than non-aeration. Keywords: Compost tea, humid acid, liquid organic fertilizer, lotus, nutrient content.

Abstract

Increasing of Rice Yield by Using Growth Promoting Endophytic Bacteria from Swamp Land (SNA Fitri and N Gofar):  Swamp land has can be used as a paddy field that will be potential as a rice source However, this land has some limiting factors such as low fertility. On the other hand, continous used of inorganic fertilizer to improve soil fertility will also have some disadvantages. Therefore,  an alternative method as  fertilizers complement is needed.  Biofertilizer  is potential to be developed.  Previous research had succeeded to explore and selected some bacteria from rice tissues grown on swamp land.  That research had found two bacteria Consortium were named as Growth Promoting Endophytic Bacterial Consortium (GPEBC).  The aims of this research were (1) to evaluate the effect of a GPEBC population density and a level of N fertilizer on plant N absorption, and rice yield in the swamp soil, and (2) to find out the optimal population density of GPEBC and optimal dosage of N fertilizer on plant N absorption and rice yields in the swamp soil.  The research used a factorial completely randomized design with 3 factors and 3 replicates.  The first factor was a kind of GPEBC which consisted of Consortium A and consortium B.  The second factors was population density of GPEBC which consisted of 0 CFU mL-1, 107 cfu mL-1, 109 cfu mL-1, and 1011 cfu mL-1.  The third factor was N-fertilizer dosages which consisted of 50% of plant nitrogen necessity (equivalent to 57.50 kg N ha-1), 75% of plant nitrogen necessity (equivalent to 86.25 kg N ha-1), and 100 % of plant N necessity (equivalent to 115 kg N ha-1).  The research showed that GPEBC of the Consortium B had a better effect on rice yiels than Consortium A.  The population density of 107 cfu mL-1 of GPEBC increased the growth and the yield of rice grown on swamp soil. Treatment combination of 75% of plant N necessity, and 107 cfu mL-1 of population density produced the best production of Consortium B  (GPEBC) for rice grown on swamp soil.

Abstract

The research was done to obtain the isolates of soil borne fungi isolated from mangrove rhizosphere which were capable of degrading petroleum hydrocarbon compounds. The soil samples were collected from South Sumatra mangrove forest which was contaminated by petroleum. The isolates obtained were selected based on their ability to survive, to grow and to degrade polycyclic aromatic hydrocarbons in medium containing petroleum residue. There were 3 isolates of soil borne hydrocarbonoclastic fungi which were able to degrade petroleum in vitro. The 3 isolates were identified as Aspergillus fumigates, A. parasiticus, and Chrysonilia sitophila. C. sitophila was the best isolate to decrease total petroleum hydrocarbon (TPH) from medium containing 5-20% petroleum residue.Keywords: Hydrocarbonoclastic fungi, hydrocarbon compounds, mangrove rhizosphere

Abstract

The concept of plants and microbes utilization for remediation measure of pollutant contaminated soil is the newest development in term of petroleum waste management technique. The research objective was to obtain wild grass types and hydrocarbonoclastic bacteria which are capable to synergize in decreasing petroleum concentration within petroleum contaminated soil. This research was conducted by using randomized completely block design. This research was conducted by using randomized completely block design. The first factor treatments were consisted of without plant, Tridax procumbens grass and Lepironia mucronata grass. The second factor treatments were consisted of without bacterium, single bacterium of Alcaligenes faecalis, single bacterium of Pseudomonas alcaligenes, and mixed bacteria of Alcaligenes faecalis with P. alcaligenes. The results showed that mixed bacteria (A.  faecalis and P. alcaligenes) were capable to increase the crown and roots dry weights of these two grasses, bacteria population, percentage of TPH (total petroleum hydrocarbon) decrease as well as TPH decrease and better pH value than that of single bacterium. The highest TPH decrease with magnitude of 70.1% was obtained on treatment of L. mucronata grass in combination with mixed bacteria.[How to Cite: Gofar N. 2013.Synergism of Wild Grass and Hydrocarbonoclastic Bacteria in Petroleum Biodegradation.

Abstract

The research was aimed to study the potency of two leguminous cover crops in enhancing tailing fertility of post tin mining with and without addition of mineral soil  and compost. This pot experiment was carried out in Greenhouse of Soil Science Department, Faculty of Agriculture, Sriwijaya University from November 2011 until March 2012. Design experiment used was a Completly Randomized Design (CRD) factorial with two factors. The first factor was type of cover corps which were Centrosema pubescens and Pueraria javanica. The second factor was plant media composition which were 100% sand tailing, 60% sand tailing + 40%  mineral soil, and  95% sand tailing + 5% compost. The result showed that N content on sand tailing after harvesting applied by compost and mineral soil was not significant by difference. Meanwhile, P content on sand tailing applied by compost was higher than mineral soil application and/or control (100% sand tailing).Keywords: Compost, legominous crop, N and P nutrients, sand tailing [How to Cite: Budianta D, N Gofar and GA Andika. 2013.

Abstract

This study aimed to identify and explore the potential of microalgae from swampland of South Sumatra as nitrogen contributor for rice plants grown on swampland. Determination of sampling points was done by looking at the presence and abundance of microalgae in the sampling locations.  The method used in the sampling is purposive sampling method. The samples were grouped into 3, i.e. culture 1 (B1) derived from rice cultivation area, culture 2 (B2) derived from land that was not cultivated with rice, and culture 3 (B3) derived from swamp water samples. The medium used to culture the microlagae was Johnson's medium. The variables measured were the number of microalgae cells and ammonium concentrations on day 1, 4, 8 and 16 of culturing. Three species of Cyanophyceae class from the swampland were identified, i.e. thread algae, Synedra sp. and Melosira sp. Those microalgae may contribute the maximum amount of available nitrogen of 21.41 ìg mL-1 in the form of ammonium to the rice plants on days 10-12. Microalgae in culture 1 can contribute nitrogen for rice plants in the form of ammonium about 16.23% - 48.71% with the cell density of 7.48 cells mL-1.
