Abstract

Efisiensi pemakaian pupuk kimia dapat didefinisikan berdasarkan aspek agronomi. Secara umum, semakin banyak hara yang diserap tanaman untuk meningkatkan hasil panen, maka tingkat efisiensi semakin tinggi. Pelacakan jumlah hara yang dapat diserap tanaman dalam meningkatkan produksi adalah komponen kunci untuk mengukur efisiensi hara. Percobaan lapangan dilakukan untuk menilai peranan rizobakteri dan fungi mikoriza arbuskular (FMA) pada berbagai konsentrasi pupuk kimia pada budidaya sorgum manis (Sorghum bicolor L. Moench). Dua galur rizobakteri (Mycobacterium senegalense 73LR dan Bacillus firmus 80JR) serta dua galur FMA (Gigaspora sp. 40MDL dan Glomus sp. 38MDL) digunakan sebagai inokulan dengan penambahan beberapa variasi konsentrasi pupuk kimia. Bobot biomasa, kandungan gula, serapan fosfor, kalium dan nitrogen dianalisis. Inokulasi rizobakteri mampu meningkatkan tinggi tanaman dan kandungan P pada taraf p<0.01, sedangkan bobot biomassa, kandungan gula, serapan P dan K pada taraf p<0.05. Inokulasi FMA saja berpengaruh nyata terhadap bobot biomassa dan kandungan N pada taraf p<0.01, sedangkan kandungan gula pada taraf p<0.05. Sementara itu, interaksi rizobakteri dan FMA mampu meningkatkan bobot biomassa, kandungan dan serapan K, serta efisiensi penyerapan hara N. Secara keseluruhan pengaruh inokulasi rizobakteri, FMA dan pupuk kimia serta interaksi faktor-faktor tersebut dapat meningkatkan bobot biomasa, kandungan gula, serapan P dan K, serta efisiensi penyerapan hara N oleh tanaman sorgum manis. Dengan demikian, pemakaian rizobakteri dan FMA berpotensi meningkatkan efisiensi penggunaan pupuk kimia, sehingga diharapkan dapat mengurangi biaya produksi budidaya sorgum manis.

Abstract

In this work we have investigated mixing in a modified orbiting screw mixer  (MOSM)  designed  for  solid-solid mixing.  Mixing  was  carried  out  using urea powder and natural zeolite powder (UZ) of three varying particle sizes (50-60, 60-80 and 80 mesh). Power consumption was calculated from the measured torque of orbit and screw, obtained from computerized records. It was found that the  mixing  process  in  the  modified  orbiting  screw  mixer  with  air  injection required a lower power consumption for each particle-size group when compared to mixing without air injection. With UZ mixing in MOSM with  air injection, the lowest E was obtained for  the 60-80 mesh particle-size group  (4,297 Joule/kg-1),whereas when mixing without  air injection, the value was  10,296 J/kg. The best mixing  operation in this experiment was achieved at NFr  =  1.18x10-3 and in the range  of  values  NRe≈  8.77x107 to  2.63x108.  Moreover,  in this  study,  we  have developed  an  equation  to  estimate the  power  consumption required  for  mixing and determined its correlation with dimensionless numbers.

Abstract

Basal stem rot caused by Ganoderma boninense is the most serious disease of oil palm (Elaeis guineensis) in Indonesia and it has caused major loss in palm oil production. Mycorrhizosphere bacteria offer possible advantages as biocontrol agents as they live and proliferate together with arbuscular mycorrhizal fungi, which have an ability to increase plant resistance against pathogens. A study was conducted to isolate mycorrhizosphere bacteria from spores of arbuscular mycorrhizal fungi and test their antagonistic effects against G. boninense in vitro. All bacterial isolates were identified based on 16S rDNA analysis and it revealed that eleven out of twenty mycorrhizosphere bacteria isolated were related to Bacillus with similarity ranging from 97 to 100%, whereas other isolates were identified as Pseudomonas, Streptomyces, Kocuria, Enterobacter, Brevundimonas, and Alcaligenes with similarities ranging from 96 to 100%. Fourteen out of twenty mycorrhizosphere bacteria showed a varying degree of inhibition towards the growth of G. boninense in vitro. Of these, isolate B10 (closely related to Bacillus subtilis ZJ06) showed the highest inhibitory effect followed by B17 (closely related to Bacillus subtilis N43). Therefore, these bacteria have a potential to be used as biocontrol agents to control basal stem rot disease caused by G. boninense in oil palm.

Abstract

Annonaceous acetogenin was extracted from Annona squamosa (Srikaya) seeds. It has cytotoxic activity against cancer cells and lower toxicity compared to other cancer drugs. Endophyte from Annonaceae is expected to have similar extracted metabolites to the host, thus increasing the economic value. This research is a preliminary study to obtain active compounds with potential as anti-cancer agents from endophytic fungi of Srikaya plants. Four endophytic fungal strains were isolated from Srikaya plants (Annona squamosa) and identified based on 28S rDNA sequence. The isolates are SKY II.3.1, SKY I.1.2, SKY II.3.2, and SKY III.3.1, and have similarity with Fusarium sp Vega760, Fusarium sp NRRL 22354 NRRL223, Nectria rigidiuscula, and Fusarium sp BOL35, respectively. The identified isolates were fermented in liquid media for three weeks. The liquid and mycelium were extracted using ethyl acetate. Whole extract of each fermented isolate was partitioned and evaporated to obtain ethyl acetate extract. Cytotoxicity assay of ethyl acetate extract was carried out at level 100 ppm by Methyl Thyazole Tetrazolium (MTT) viability test towards MCF-7 (breast cancer cell). The result indicated that each ethyl acetate extract could inhibit the viability of cell MCF-7 with 11.34, 99.78, 91.48, and 96.84%, for SKY II.3.1, SKY I.1.2, SKY II.3.2, and SKY III.3.1, respectively. Based on the results of cytotoxicity assay on MCF-7 breast cancer cells, endophytic fungi isolates SKY I.1.2, SKY II.3.2, and SKY III.3.1 are potential as sources of anti-breast cancer compounds.

Abstract

Hydroxyoctadecadienoic acid (HODE) is one of hydroxy fatty acids that has anticancer activity.  HODE was previously produced by chemical synthesis or bioconversion from linoleic acid. This is the first paper reported production of HODE by Curvularia lunata an endophytic fungi of Cibotium barometz. Various carbon and hydrogen sources have been tested for their effects on the production of  HODE by C. lunata. Glucose, lactose, maltose, xylose, and sucrose were used as carbon sources, while yeast extract, monosodium glutamate, urea, and NH4Cl were used as nitrogen sources. Fermentation was done using 100 ml medium in 250 ml Erlenmeyer flask at 150 rpm, 28 oC for 10 days.  HODE products were analyzed by high pressure liquid chromatography using C18 coloumn and eluted by gradient system of acetonitril-water from 15% to 100%. Glucose  and monosodium glutamate were found to be the best carbon and nitrogen source.  The optimum concentration of glucose and monosodium glutamate for the production of HODE were 10 mg L-1 and 12 mg L-1 respectively.

Abstract

Three proteins were discovered, they were: TF2 from fruit, TS3 from seed and TR3 from root of Trichosanthes cucumerina L. var anguina (L.) Haines by extraction with Phosphate Buffer Saline (PBS). The proteins were precipitated using 80% saturated ammonium sulphate and then were dialysed using cellophane. Furthermore, the dialysate was fractionated through gel filtration chromatography. The highest protein yield was 1.109%, resulted from TS3, then 0.356% from TR3, and the lowest was 0.014% from TF2. Characterization of the proteins using SDS-PAGE indicated that all of the protein fractions showed more than one sub unit molecular masses (Mr) in the range of 16 - 29 kDa. The toxicity (LC50) of proteins on brine shrimp lethality test were within range of 19 µg/ml - 25 µg/ml. The cytotoxicities of the TR3 and TS3 proteins on cancer cell line indicated that both of the active proteins inhibit proliferation of HeLa and K-562 cells with IC50 up to 45 µg/ml. Keywords : Trichosanthes cucumerina L. var anguina (L.), plant part, protein, yield, toxicity, cytotoxicity, molecular mass.

Abstract

Slow release fertilizer (SRF) of urea is prepared by using zeolite as the matrix. Mixing of urea and zeolite is carried out in orbiting screw mixer. The effects of rotation speed and orbital speed of the mixer and particle size on power consumption, homogeneity, mixing time and specific energy consumption are evaluated. The experimental results show that higher orbital speed gives higher power consumption. Power consumption is dominated by mixer rotation motion. Smaller particle size needs higher power for mixing process. Nitrogen mass fraction ranges from 0.45 to 0.49 when mixture reaches homogeneity. The mixing time required is about 5 – 12 minutes for particle size of >60 and >80 mesh and 7 – 14 minutes for particle size of >50 mesh. At constant orbit speed, the higher the screw rotation speed, the shorter time needed to reach mixture homogeneity. Specific energy consumption of mixing process increases with decreasing particle size. For the three particle size groups of >80 mesh, >60 mesh and >50 mesh, the lowest specific energy consumption is given by combination of orbital speed of 5 rpm and rotation speed of 50 rpm; while for particle size of >60 mesh and >80 mesh, it can obtained by combination of orbital speed of 5 rpm and rotation speed of 67,5 rpm and orbital speed 5 rpm and rotation speed 30 rpm, respectively. The lowest specific energy consumptions is gained by combination of orbital and rotation speeds of 5 and 50 rpm with particle size of >50 mesh.
