Potency of Plant Bioactive Compounds from the Genus PhyllanthusÂ as Hepatitis B Virus Replication InhibitorIn this research, simulations of molecular docking of Phyllanthus bioactive compounds were performed into the core protein of HBV. This simulation aimed to predict the interaction between compounds with virus core protein causing disruption of capsid formation and inhibiting its replication. The docking simulation was completed by Molegro Virtual Docker 6.0. The 3D stable conformation of molecule structures were docked into HBV core protein downloaded from Protein Data Bank, then the results were analyzed to view the minimum energy and interactions that occurred. The coordinate docking was done at the same coordinate as the previously docked reference ligand position and was validated. From the results it was known that repandusinic acid formed the most stable affinity bond with amino acid residues of viral core proteins. Interaction of B chain forming hydrogen bonds with the amino acid residues of Thr 33, Trp 102, Phe 23, Leu 140, Tyr 118 and Ser 141, and C chain with Thr 128, Val 124 and Glu 117.These compounds can be used as marker for anti HBV.Keyword: Bioactive compounds, core protein, HBV , molecular docking, PhyllanthusÂ ABSTRAKPada penelitian ini dilakukan simulasi penambatan molekul senyawa-senyawa bioaktif Phyllanthus ke dalam protein inti virus hepatitis B.

In Vitro Propagation of Kepok Banana var. Unti Sayang Resistant to Blood Disease through Shoot ProliferationABSTRACTKepok is a popular banana variety but sensitive to blood disease caused by Ralstonia solanacearum (Smith). The discovery of a natural mutant of Kepok banana var. Unti Sayang from Sulawesi which male bud falls naturally, is a shortcut to bypass the chains of the spread of blood disease, since the disease is transmitted by insects through the wounds of the male buds. The superior mutant needs to be mass propagated and disseminated to endemic areas to inhibit the spread of blood disease. To achieve that goal, an efficient and effective techniques of in vitro shoot proliferation needs to be developed. Shoot proliferation was performed by addition of BAP, thidiazuron and adenine sulphate. The results showed that the best medium for shoot multiplication was B2T5A (MS+2 mg/L BAP+0,5 mg/L TDZ+20 mg/L adenine sulphate), and for shoot growth was B4A (MS+4 mg/L BAP+20 mg/L adenine sulphate). Rooting was induced on MS medium without hormones. Acclimatization of plantlets on mixed soil, compost and husks with a ratio of 1:1:1 resulted in 92,35% survival rate.Keywords: blood disease, in vitro shoot, Â male budless, natural mutant, var.

Decolorization of Sumifix Blue and Reactive Red 2 Textile Dyes by Microbes Isolated from Textile Waste WaterAzo dyes represent the most commonly used group of dyes in textile industry and discharged into industrial effluents worldwide. Aims of this study are to isolate microbe from textile waste water and to determine their ability to decolorize Sumifix Blue and Reactive Red 2 textile dyes. Microbe was isolated from textile effluent of PT Timatex, Salatiga. The activity for decolorization was assayed by inoculating microbial isolates into dye containing medium. Living and nonliving cell were incubated in dye containing medium in order to determine if microbial cells involved in decolorizing dye. Five different microbial isolates have been isolated from textile waste water.Â Isolates IBLTT_1 and IBLTT_5 showed the highest activity to decolorize Sumifix Blue, and only isolate IBLTT_1 showed the highest capability in decolorizing Reactive Red 2. Both isolates indicated positive potential towards biotreatment of textile waste water. Further results confirmed that decolorization was due to biodegradation, rather than physical adsorption by inactive cells.Keywords: decolorization, microbial isolation, Reactive Red 2, Sumifix Blue, textile effluentÂ ABSTRAKPewarna azo mewakili kelompok pewarna yang umum digunakan pada industri tekstil dan banyak dijumpai di buangan limbah industri tekstil. Tujuan dari penelitian ini adalah untuk mendapatkan isolat dari limbah tekstil dan untuk mengetahui kemampuannya dalam mendekolorisasi pewarna tekstil Sumifix Blue dan Reactive Red 2. Sampel diperoleh dari limbah industri tekstil PT Timatex, Salatiga. Uji kemampuan dekolorisasi dilakukan dengan menginokulasikan isolat mikroba ke dalam medium Nutrient Broth yang mengandung pewarna. Untuk mengetahui apakah sel mikroba terlibat dalam dekolorisasi pewarna, maka sel hidup dan mati diinokulasi pada medium tersebut. Lima isolat yang berbeda diperoleh dalam penelitian ini. Isolat IBLTT_1 dan IBLTT_5 merupakan isolat dengan kemampuan dekolorisasi Sumifix Blue tertinggi. Isolat IBLTT_1 juga merupakan isolat dengan kemampuan dekolorisasi Reactive Red 2 tertinggi. Kedua isolat tersebut menunjukkan potensi positif terhadap pengolahan limbah tekstil. Hasil lebih lanjut menegaskan bahwa dekolorisasi Sumifix Blue dan Reactive Red 2 disebabkan oleh proses biodegradasi, bukan diadsorpsi oleh sel yang mati.Kata kunci: dekolorisasi, isolat mikroba, limbah tekstil, Reactive Red 2, Sumifix Blue

Ability of Active Compound Extract of Endophytic Bacteria to Inhibit the Growth of Fusarium oxysporum f.sp. in Oil PalmÂ ABSTRACTWilt vessels disease in oil palm plants is caused by Fusarium oxysporum f.sp. This disease is very harmful because of its ability to kill the infected oil palm plant in less than a year. Endophytic bacteria are likely to be biological controllers for the disease because of their ability to produce bioactive antifungal compounds. Isolation of endophytic bacteria from oil palm plant and activity test of their active compounds against F. oxysporum f.sp. in vitro had been done. Antagonistic test of endophytic bacterial isolates against F. oxysporum f.sp. was carried out using a double culture method. The potential endophytic bacterial isolates were extracted using ethyl acetate solvent for their active compounds, which were then tested for its activity in inhibiting the growth of F. oxysporum f.sp. The results showed that the active compound extract of B11 endophytic bacteria with the incubation time of 24 and 54 hours gave the growth inhibition of F. oxysporum f.sp. at the level of 29.23% and 43.85%, respectively.Keywords: antagonistic test, bioactive compound, endophytic bacteria, F. oxysporum f.sp., oil palmÂ ABSTRAKPenyakit layu pembuluh pada tanaman kelapa sawit disebabkan oleh Fusarium oxysporum f.sp.
