Abstract

Composting is a natural microbial process involving organic residues. At the end of this process, the low-value organic residues are consequently converted into higher-value products. It has become more widely accepted among those interested in organic farming, since the process is also considered as a practical alternative for use in the management of organic residues. However, the use of compost as organic fertilisers is invariably associated with the constraint in their production. The Aspergillus terreus SUK-1 is known to produce large amounts of enzyme ß-glucosidase, and thus could be effective for the degradation of cellulose. EM4 is an inoculant comprising 90% of the bacteria involved in fermentation and in lactic acid production. In this study, Aspergillus terreus SUK-1 and EM4, together with chicken dung as control, were used to determine and compare their effects on the composting of oil palm fruit fibres. The experiment design was randomized completed design with three treatments, namely Control (with chicken manure), Aspergillus terreus SUK-1 and EM4. Each treatment is replicated five times. The parameter observed was temperature, pH, humidity, carbon contents, nitrogen contents and C/N ratio. the result of this study showed that EM4 is more than effective compare to another for composting of oil palm fruit fibres. The pH, carbon contents, nitrogen contents and C/N ratio values of EM4 treatment at the end of composting were 7.53, 20.54, 2.94, 7.02, respectivel and EM4 give ideal temprature for compos process campare to Aspergillus terreus and control. Based on analyses of variance, EM4 showed significant differences with Aspergillus in temperature, nitrogen and carbon contents, while control in all parameters. for commercially purpose, EM4 is more recommended to use in composting of oil palm fruit fibres because of it is cheaper, easy to obtain in the market and high quality of composting.

Abstract

The objective of this research is to be able to observe the results of the integration as well as the expression of the desaturase gene in the antisense conformation. The selection of an appropriate tissue culture media is required for a faster growth, development and regeneration of the explant. PCR analysis shows that the putative transgenes were successfully inserted into the target tissue. They were then analysed via gas chromatography to detect its effect on the fatty acid profile. As a result, it was discovered that the three plants contained a higher level of saturated fatty acids (C:12 – C:18), as well as a reduced level of unsaturated fatty acids (C18:1 – C18:3). This probably shows that the stearoyl-ACP desaturase gene might be able to block or reduce the levels of unsaturated fatty acid while increasing the levels of saturated fatty acid. As this are preliminary results further work needs to be carried out to verify this observation.

Abstract

Giam Siak Kecil Biosphere-Bukit Batu (GSK-BB) is Riau  peatlands area which is largest composed by lowland peat swamp forest ecosystem. Seeing peatland ecosystem getting extreme, there will be small possibility that soil microbes are able to breed optimally, but microbes in tropical land has not been explored. However, the high content of organic matter, allowing soil microbial activity in the organic matter recycle that essential to life such as nitrogen cycle. Non-symbiotic nitrogen fixing bacteria is a free-living bacteria and plays a role in the supply of N in the soil. The results of the isolated and characterization of single bacterial isolates obtained 31 non-symbiotic N fixing of GSK-BB peat Biosphere which allegedly largest to genus Azotobacter, Azospirillium and Clostridium pasteurianum as well as the results of clear zone isolates on the medium modification, from the single isolates contained 14 isolate that potentially in a non-symbiotic N with the largest ratio of clear zone obtained HTA1 10-4 NS-2, HTA1 10-4 NS-1, HTA 4 10-4 NA-1 dan HTA5 10-4 NS-2.

Abstract

One of the problem of Eurycoma longifolia Jack propagation was low germination percentage due to recalcitrant seeds and slow growth of seedling from cutting propagation. To overcome this problem is required propagation of Eurycoma longifolia via in vitro culture. The objective of this research was to know the effect of Auxin (2,4-D and NAA) and Cytokines (BAP and Kinetin)  on Eurycoma longifolia callus induction via leaf and petiole explants. In this study, we used plant growth regulator of 2,4 D, NAA, BAP and Kinetin in several levels.  The observed variables were appearing callus time, callus color and callus texture. The results of this study showed that MS medium supplemented with 1 ppm NAA+ 1 ppm BAP was able to induce callus formation in leaf explant for 6 months after culture. While MS medium supplemented with 1 ppm 2,4-D, 1 ppm BAP, combination of 2,4-D and Kinetin and combination of 2,4-D and BAP can induce callus formation from petiole. All the callus formation has yellow color and yellow brown color. The petiole explant that is grown in MS medium supplemented with 1 ppm BAP induced of callus in short time (18 days after culture).
